Any rule that specifies the behaviour of the originating NG-RAN node shall be possible to be verified with information that is visible within the system. The following specification principles have been applied for the procedure text in clause 8: - The procedure text discriminates between: 1) Functionality which "shall" be executed The procedure text indicates that the receiving node "shall" perform a certain function Y under a certain condition. If the receiving node supports procedure X but cannot perform functionality Y requested in the initiating message of a Class 1 EP, the receiving node shall respond with the message used to report unsuccessful outcome for this procedure, containing an appropriate cause value. 2) Functionality which "shall, if supported" be executed The procedure text indicates that the receiving node "shall, if supported," perform a certain function Y under a certain condition. If the receiving node supports procedure X, but does not support functionality Y, the receiving node shall proceed with the execution of the EP, possibly informing the requesting node about the not supported functionality. - Any required inclusion of an optional IE in a response message is explicitly indicated in the procedure text. If the procedure text does not explicitly indicate that an optional IE shall be included in a response message, the optional IE shall not be included. For requirements on including Criticality Diagnostics IE, see section 10. 4.2 Forwards and backwards compatibility The forwards and backwards compatibility of the protocol is assured by a mechanism where all current and future messages, and IEs or groups of related IEs, include ID and criticality fields that are coded in a standard format that will not be changed in the future. These parts can always be decoded regardless of the standard version. 4.3 Specification notations For the purposes of the present document, the following notations apply: Procedure When referring to an elementary procedure in the specification the Procedure Name is written with the first letters in each word in upper case characters followed by the word "procedure", e.g. Handover Preparation procedure. Message When referring to a message in the specification the MESSAGE NAME is written with all letters in upper case characters followed by the word "message", e.g. HANDOVER REQUEST message. IE When referring to an information element (IE) in the specification the Information Element Name is written with the first letters in each word in upper case characters and all letters in Italic font followed by the abbreviation "IE", e.g. PDU Session ID IE. Value of an IE When referring to the value of an information element (IE) in the specification the "Value" is written as it is specified in sub clause 9.2 enclosed by quotation marks, e.g. "Value". 5 XnAP services The present clause describes the services an NG-RAN node offers to its neighbours. 5.1 XnAP procedure modules The Xn interface XnAP procedures are divided into two modules as follows: 1. XnAP Basic Mobility Procedures; 2. XnAP Global Procedures; The XnAP Basic Mobility Procedures module contains procedures used to handle the UE mobility within NG-RAN. The Global Procedures module contains procedures that are not related to a specific UE. The procedures in this module are in contrast to the above module involving two peer NG-RAN nodes. 5.2 Parallel transactions Unless explicitly indicated in the procedure specification, at any instance in time one protocol peer shall have a maximum of one ongoing XnAP procedure related to a certain UE. 6 Services expected from signalling transport The signalling connection shall provide in sequence delivery of XnAP messages. XnAP shall be notified if the signalling connection breaks. Xn signalling transport is specified in TS 38.422 [4]. 7 Functions of XnAP The functions of XnAP are specified in TS 38.420 [3]. 8 XnAP procedures 8.1 Elementary procedures In the following tables, all EPs are divided into Class 1 and Class 2 EPs.

If the procedure concerns a conditional handover, parallel transactions are allowed. Possible parallel requests are identified by the target cell ID when the source UE AP IDs are the same. The procedure uses UE-associated signalling. 8.2.1.2 Successful Operation Figure 8.2.1.2-1: Handover Preparation, successful operation The source NG-RAN node initiates the procedure by sending the HANDOVER REQUEST message to the target NG-RAN node. When the source NG-RAN node sends the HANDOVER REQUEST message, it shall start the timer TXnRELOCprep. If the Conditional Handover Information Request IE is contained in the HANDOVER REQUEST message, the target NG-RAN node shall consider that the request concerns a conditional handover and shall include the Conditional Handover Information Acknowledge IE in the HANDOVER REQUEST ACKNOWLEDGE message. If the Target NG-RAN node UE XnAP ID IE is contained in the Conditional Handover Information Request IE included in the HANDOVER REQUEST message, then the target NG-RAN node shall remove the existing prepared conditional HO identified by the Target NG-RAN node UE XnAP ID IE and the Target Cell Global ID IE. It is up to the implementation of the target NG-RAN node when to remove the HO information. Upon reception of the HANDOVER REQUEST ACKNOWLEDGE message, the source NG-RAN node shall stop the timer TXnRELOCprep and terminate the Handover Preparation procedure. If the procedure was initiated for an immediate handover, the source NG-RAN node shall start the timer TXnRELOCoverall. The source NG-RAN node is then defined to have a Prepared Handover for that Xn UE-associated signalling. For each E-RAB ID IE included in the QoS Flow To Be Setup List IE in the HANDOVER REQUEST message, the target NG-RAN node shall, if supported, store the content of the IE in the UE context and use it for subsequent inter-system handover. If the Masked IMEISV IE is contained in the HANDOVER REQUEST message the target NG-RAN node shall, if supported, use it to determine the characteristics of the UE for subsequent handling. At reception of the HANDOVER REQUEST message the target NG-RAN node shall prepare the configuration of the AS security relation between the UE and the target NG-RAN node by using the information in the UE Security Capabilities IE and the AS Security Information IE in the UE Context Information IE, as specified in TS 33.501 [28]. Upon reception of the PDU Session Resource Setup List IE, contained in the HANDOVER REQUEST message, the target NG-RAN node shall behave the same as specified in TS 38.413 [5] for the PDU Session Resource Setup procedure. The target NG-RAN node shall report in the HANDOVER REQUEST ACKNOWLEDGE message the successful establishment of the result for all the requested PDU session resources. When the target NG-RAN node reports the unsuccessful establishment of a PDU session resource, the cause value should be precise enough to enable the source NG-RAN node to know the reason for the unsuccessful establishment. For each PDU session if the PDU Session Aggregate Maximum Bit Rate IE is included in the PDU Session Resources To Be Setup List IE contained in the HANDOVER REQUEST message, the target NG-RAN node shall store the received PDU Session Aggregate Maximum Bit Rate in the UE context and use it when enforcing traffic policing for Non-GBR QoS flows for the concerned UE as specified in TS 23.501 [7]. For each QoS flow for which the source NG-RAN node proposes to perform forwarding of downlink data, the source NG-RAN node shall include the DL Forwarding IE set to "DL forwarding proposed" within the Data Forwarding and Offloading Info from source NG-RAN node IE in the PDU Session Resources To Be Setup List IE in the HANDOVER REQUEST message. The source NG-RAN node shall include the DL Forwarding IE set to "DL forwarding proposed" for all the QoS flows mapped to a DRB, if it requests a DAPS handover for that DRB. For each PDU session that the target NG-RAN node decides to admit the data forwarding for at least one QoS flow, the target NG-RAN node includes the PDU Session level DL data forwarding GTP-U Tunnel Endpoint IE within the Data Forwarding Info from target NG-RAN node IE in the PDU Session Resource Admitted Info IE contained in the PDU Session Resources Admitted List IE in the HANDOVER REQUEST ACKNOWLEDGE message. For each QoS flow for which the source NG-RAN node has not yet received the SDAP end marker packet if QoS flow re-mapping happened before handover, the source NG-RAN node shall include the UL Forwarding Proposal IE within the Data Forwarding and Offloading Info from source NG-RAN node IE in the HANDOVER REQUEST message, and if the target NG-RAN node decides to admit uplink data forwarding for at least one QoS flow, the target NG-RAN node may include the PDU Session Level UL Data Forwarding UP TNL Information IE in the Data Forwarding Info from target NG-RAN node IE in the PDU Session Resources Admitted Item IE contained in the PDU Session Resources Admitted List IE in the HANDOVER REQUEST ACKNOWLEDGE message to indicate that it accepts the uplink data forwarding. For each PDU session resource successfully setup at the target NG-RAN, the target NG-RAN node may allocate resources for additional Xn-U PDU session resource GTP-U tunnels, indicated in the Secondary Data Forwarding Info from target NG-RAN node List IE. For each PDU session in the HANDOVER REQUEST message, if the Alternative QoS Parameters Set List IE is included in the GBR QoS Flow Information IE in the PDU Session Resources To Be Setup List IE, the target NG-RAN node may accept the setup of the involved QoS flow when notification control has been enabled if the requested QoS parameters set or at least one of the alternative QoS parameters sets can be fulfilled at the time of handover as specified in TS 23.501 [7]. In case the target NG-RAN node accepts the handover fulfilling one of the alternative QoS parameters it shall indicate the alternative QoS parameters set which it can currently fulfil in the Current QoS Parameters Set Index IE within the PDU Session Resources Admitted List IE of the HANDOVER REQUEST ACKNOWLEDGE message while setting the QoS parameters towards the UE according to the requested QoS parameters set as specified in TS 23.501 [7]. For each DRB for which the source NG-RAN node proposes to perform forwarding of downlink data, the source NG-RAN node shall include the DRB ID IE and the mapped QoS Flows List IE within the Source DRB to QoS Flow Mapping List IE contained in the PDU Session Resources To Be Setup List IE in the HANDOVER REQUEST message. The source NG-RAN node may include the QoS Flow Mapping Indication IE in the Source DRB to QoS Flow Mapping List IE to indicate that only the uplink or downlink QoS flow is mapped to the DRB. If the target NG-RAN node decides to use the same DRB configuration and to map the same QoS flows as the source NG-RAN node, the target NG-RAN node includes the DL Forwarding GTP Tunnel Endpoint IE within the Data Forwarding Response DRB List IE in the HANDOVER REQUEST ACKNOWLEDGE message to indicate that it accepts the proposed forwarding of downlink data for this DRB. The target NG-RAN node may additionally include the Redundant DL Forwarding UP TNL Information IE if at least one of the QoS flow mapped to the DRB is eligible to the redundant transmission feature as indicated in the Redundant QoS Flow Indicator IE within the PDU Session Resource To Be Setup List IE received in the HANDOVER REQUEST message for the QoS flow. If the HANDOVER REQUEST ACKNOWLEDGE message contains the UL Forwarding GTP Tunnel Endpoint IE for a given DRB in the Data Forwarding Response DRB List IE within Data Forwarding Info from target NG-RAN node IE in the PDU Session Resources Admitted List IE and the source NG-RAN node accepts the data forwarding proposed by the target NG-RAN node, the source NG-RAN node shall perform forwarding of uplink data for the DRB. If the HANDOVER REQUEST includes PDU session resources for PDU sessions associated to S-NSSAIs not supported by target NG-RAN, the target NG-RAN shall reject such PDU session resources. In this case, and if at least one PDU Session Resource To Be Setup Item IE is admitted, the target NG-RAN shall send the HANDOVER REQUEST ACKNOWLEDGE message including the PDU Session Resources Not Admitted List IE listing corresponding PDU sessions rejected at the target NG-RAN. If the Mobility Restriction List IE is - contained in the HANDOVER REQUEST message, the target NG-RAN node shall - store the information received in the Mobility Restriction List IE in the UE context; - use this information to determine a target for the UE during subsequent mobility action for which the NG-RAN node provides information about the target of the mobility action towards the UE, except when one of the PDU sessions has a particular ARP value (TS 23.501 [7]) in which case the information shall not apply; - use this information to select a proper SCG during dual connectivity operation. - use this information to select proper RNA(s) for the UE when moving the UE to RRC_INACTIVE. - not contained in the HANDOVER REQUEST message, the target NG-RAN node shall - consider that no roaming and no access restriction apply to the UE. If the Trace Activation IE is included in the HANDOVER REQUEST message the target NG-RAN node shall, if supported, initiate the requested trace function as specified in TS 32.422 [23]. If the Index to RAT/Frequency Selection Priority IE is contained in the HANDOVER REQUEST message, the target NG-RAN node shall store this information and use it as defined in TS 23.501 [7]. If the UE Context Reference at the S-NG-RAN IE is contained in the HANDOVER REQUEST message the target NG-RAN node may use it as specified in TS 37.340 [8]. In this case, the source NG-RAN node may expect the target NG-RAN node to include the UE Context Kept Indicator IE set to "True" in the HANDOVER REQUEST ACKNOWLEDGE message, which shall use this information as specified in TS 37.340 [8]. For each PDU session, if the Network Instance IE is included in the PDU Session Resource To Be Setup List IE and the Common Network Instance IE is not present, the target NG-RAN node shall, if supported, use it when selecting transport network resource as specified in TS 23.501 [7]. Redundant transmission: - For each PDU session, if the Redundant UL NG-U UP TNL Information at UPF IE is included in the PDU Session Resource To Be Setup List IE, the target NG-RAN node shall, if supported, use it as the uplink termination point for the user plane data for the redundant transmission for the concerned PDU session. - For each PDU session, if the Additional Redundant UL NG-U UP TNL Information at UPF List IE is included in the PDU Session Resource To Be Setup List IE, the target NG-RAN node shall, if supported, use them as the uplink termination points for the user plane data for the redundant transmission for the concerned PDU session. - For each PDU session, if the Redundant Common Network Instance IE is included in the PDU Session Resource To Be Setup List IE, the target NG-RAN node shall, if supported, use it when selecting transport network resource for the redundant transmission as specified in TS 23.501 [7]. - For each PDU session, if the Redundant PDU Session Information IE is included in the PDU Session Resource To Be Setup List IE contained in the HANDOVER REQUEST message, the target NG-RAN node shall, if supported, store the received information in the UE context and set up the redundant user plane for the concerned PDU session, as specified in TS 23.501 [7]. If the TSC Traffic Characteristics IE is included in the QoS Flows To Be Setup List in the PDU Session Resource To Be Setup List IE, the target NG-RAN node shall, if supported, use it as specified in TS 23.501 [7]. For each PDU session, if the Common Network Instance IE is included in the PDU Session Resource To Be Setup List IE or in the Additional UL NG-U UP TNL Information at UPF List IE, or in the Additional Redundant UL NG-U UP TNL Information at UPF List IE, the target NG-RAN node shall, if supported, use it when selecting transport network resource for the concerned NG-U transport bearer as specified in TS 23.501 [7]. For each PDU session for which the Security Indication IE is included in the PDU Session Resource To Be Setup List IE and the Integrity Protection Indication IE or Confidentiality Protection Indication IE is set to "required", the target NG-RAN node shall perform user plane integrity protection or ciphering, respectively. If the NG-RAN node is not able to perform the user plane integrity protection or ciphering, it shall reject the setup of the PDU Session Resources with an appropriate cause value. If the NG-RAN node is an ng-eNB, it shall reject all PDU sessions for which the Integrity Protection Indication IE is set to "required". For each PDU session for which the Security Indication IE is included in the PDU Session Resource To Be Setup List IE and the Integrity Protection Indication IE or the Confidentiality Protection Indication IE is set to "preferred", the target NG-RAN node should, if supported, perform user plane integrity protection or ciphering, respectively and shall notify the SMF whether it succeeded the user plane integrity protection or ciphering or not for the concerned security policy. For each PDU session for which the Maximum Integrity Protected Data Rate IE is included in the Security Indication IE in the PDU Session Resources To Be Setup List IE, the NG-RAN node shall store the respective information and, if integrity protection is to be performed for the PDU session, it shall enforce the traffic corresponding to the received Maximum Integrity Protected Data Rate IE, for the concerned PDU session and concerned UE, as specified in TS 23.501 [7]. For each PDU session for which the Security Indication IE is included in the PDU Session Resource To Be Setup List IE and the Integrity Protection Indication IE or Confidentiality Protection Indication IE is set to "not needed", the target NG-RAN node shall not perform user plane integrity protection or ciphering, respectively, for the concerned PDU session. For each PDU session, if the Additional UL NG-U UP TNL Information List IE is included in the PDU Session Resources To Be Setup List IE contained in the HANDOVER REQUEST message, the target NG-RAN node may forward the UP transport layer information to the target S-NG-RAN node as the uplink termination point for the user plane data for this PDU session split in different tunnel.

In case that the Xn handover is a DAPS handover, the SN Status Transfer procedure may also be used to transfer the uplink PDCP SN and HFN receiver status, or the downlink PDCP SN and HFN transmitter status for a DRB associated with RLC-UM and configured with DAPS as described in TS 38.300 [9]. If the SN Status Transfer procedure is applied in the course of dual connectivity or RRC connection re-establishment in the subsequent specification text - the behaviour of the NG-RAN node from which the DRB context is transferred, i.e. the NG-RAN node involved in dual connectivity or RRC connection re-establishment, from which data is forwarded, is specified by the behaviour of the "source NG-RAN node", - the behaviour of the NG-RAN node to which the DRB context is transferred, i.e., the NG-RAN node involved in dual connectivity or RRC connection re-establishment, to which data is forwarded, is specified by the behaviour of the "target NG-RAN node". The procedure uses UE-associated signalling. 8.2.2.2 Successful Operation Figure 8.2.2.2-1: SN Status Transfer, successful operation The source NG-RAN node initiates the procedure by stop assigning PDCP SNs to downlink SDUs and stop delivering UL SDUs towards the 5GC and sending the SN STATUS TRANSFER message to the target NG-RAN node at the time point when it considers the transmitter/receiver status to be frozen. The target NG-RAN node using full configuration for this handover as per TS 38.300 [9] or for the MR-DC operations as per TS 37.340 [8] shall ignore the information received in this message. In case of MR-DC, if the target NG-RAN node performs PDCP SN length change or RLC mode change for a DRB as specified in TS 37.340 [8], it shall ignore the information received for that DRB in this message. In case that the Xn handover is a DAPS handover, the source NG-RAN node may continue assigning PDCP SNs to downlink SDUs and delivering uplink SDUs toward the 5GC when initiating this procedure for DRBs not configured with DAPS as in TS 38.300 [9]. For each DRB in the DRBs Subject to Status Transfer List IE, the source NG-RAN node shall include the DRB ID IE, the UL COUNT Value IE and the DL COUNT Value IE. The source NG-RAN node may also include in the SN STATUS TRANSFER message the missing and the received uplink SDUs in the Receive Status of UL PDCP SDUs IE for each DRB for which the source NG-RAN node has accepted the request from the target NG-RAN node for uplink forwarding. For each DRB in the DRBs Subject to Status Transfer List IE, the target NG-RAN node shall not deliver any uplink packet which has a PDCP-SN lower than the value contained within the UL COUNT Value IE. For each DRB in the DRBs Subject to Status Transfer List IE, the target NG-RAN node shall use the value of the PDCP SN contained within the DL COUNT Value IE for the first downlink packet for which there is no PDCP-SN yet assigned. If the Receive Status of UL PDCP SDUs IE is included for at least one DRB in the SN STATUS TRANSFER message, the target NG-RAN node may use it in a Status Report message sent to the UE over the radio interface. If the SN STATUS TRANSFER message contains in the DRBs Subject To Status Transfer List IE the Old QoS Flow List - UL End Marker expected IE, the target NG-RAN shall be prepared to receive the SDAP end marker for the QoS flow via the corresponding DRB, as specified in TS 38.300 [8]. 8.2.2.3 Unsuccessful Operation Not applicable. 8.2.2.4 Abnormal Conditions If the target NG-RAN node receives this message for a UE for which no prepared handover exists at the target NG-RAN node, the target NG-RAN node shall ignore the message. 8.2.3 Handover Cancel 8.2.3.1 General The Handover Cancel procedure is used to enable a source NG-RAN node to cancel an ongoing handover preparation or an already prepared handover.

For dual connectivity, the UE Context Release procedure is initiated by the M-NG-RAN node to initiate the release the UE context at the S-NG-RAN node. For dual connectivity specific mobility scenarios specified in TS 37.340 [8], where SCG radio resources in the S-NG-RAN node are kept, only resources related to the UE-associated signalling connection between the M-NG-RAN node and the S-NG-RAN node are released. For UE context retrieval, the UE Context Release procedure is initiated by the new NG-RAN node to indicate to the old NG-RAN node that radio and control plane resources for the associated UE context are allowed to be released. The procedure uses UE-associated signalling. 8.2.7.2 Successful Operation Figure 8.2.7.2-1: UE Context Release, successful operation for handover Figure 8.2.7.2-2: UE Context Release, successful operation for dual connectivity Figure 8.2.7.2-3: UE Context Release, successful operation for UE context retrieval Handover The UE Context Release procedure is initiated by the target NG-RAN node.

If the initiating NG-RAN node1 does not receive either XN SETUP RESPONSE message or XN SETUP FAILURE message, the NG-RAN node1 may reinitiate the Xn Setup procedure towards the same NG-RAN node, provided that the content of the new XN SETUP REQUEST message is identical to the content of the previously unacknowledged XN SETUP REQUEST message. If the initiating NG-RAN node1 receives an XN SETUP REQUEST message from the peer entity on the same Xn interface: - In case the NG-RAN node1 answers with an XN SETUP RESPONSE message and receives a subsequent Xn SETUP FAILURE message, the NG-RAN node1 shall consider the Xn interface as non operational and the procedure as unsuccessfully terminated according to sub clause 8.4.1.3. - In case the NG-RAN node1 answers with an XN SETUP FAILURE message and receives a subsequent XN SETUP RESPONSE message, the NG-RAN node1 shall ignore the XN SETUP RESPONSE message and consider the Xn interface as non operational. 8.4.2 NG-RAN node Configuration Update 8.4.2.1 General The purpose of the NG-RAN node Configuration Update procedure is to update application level configuration data needed for two NG-RAN nodes to interoperate correctly over the Xn-C interface.

The procedure uses non UE-associated signalling. 8.4.3.2 Successful Operation Figure 8.4.3.2-1: Cell Activation, successful operation The NG-RAN node1 initiates the procedure by sending the CELL ACTIVATION REQUEST message to the peer NG-RAN node2. Upon receipt of this message, the NG-RAN node2 should activate the cell/s indicated in the CELL ACTIVATION REQUEST message and shall indicate in the CELL ACTIVATION RESPONSE message for which cells the request was fulfilled. If case of network sharing with multiple cell ID broadcast with shared Xn-C signalling transport, as specified in TS 38.300 [9], the CELL ACTIVATION REQUEST message and the CELL ACTIVATION RESPONSE message shall include the Interface Instance Indication IE to identify the corresponding interface instance. Interactions with NG-RAN Configuration Update procedure: The NG-RAN node2 shall not send the NG-RAN CONFIGURATION UPDATE message to the NG-RAN node1 just for the reason of the cell/s indicated in the CELL ACTIVATION REQUEST message changing cell activation state, as the receipt of the CELL ACTIVATION RESPONSE message by the NG-RAN node1 is used to update the information about the activation state of NG-RAN node2 cells in the NG-RAN node1. 8.4.3.3 Unsuccessful Operation Figure 8.4.3.3-1: Cell Activation, unsuccessful operation If the NG-RAN node2 cannot activate any of the cells indicated in the CELL ACTIVATION REQUEST message, it shall respond with the CELL ACTIVATION FAILURE message with an appropriate cause value.

The procedure either resets the Xn interface or selected UE contexts. This procedure doesn’t affect the application level configuration data exchanged during, e.g., the Xn Setup procedure. The procedure uses non UE-associated signalling. 8.4.4.2 Successful Operation Figure 8.4.4.2-1: Reset, successful operation The procedure is initiated with the RESET REQUEST message sent from the NG-RAN node1 to the NG-RAN node2. Upon receipt of this message, - if the RESET REQUEST message indicates full reset the NG-RAN node2 shall abort any other ongoing procedures over Xn between the NG-RAN node1 and the NG-RAN node2. The NG-RAN node2 shall delete all the context information related to the NG-RAN node1, except the application level configuration data exchanged during the Xn Setup or the NG-RAN node Configuration Update procedures and release the corresponding resources. After completion of release of the resources, the NG-RAN node2 shall respond with the RESET RESPONSE message. - if the RESET REQUEST message indicates partial reset, the NG-RAN node2 shall abort any other ongoing procedures only for the indicated UE associated signalling connections identified either by the NG-RAN node1 UE XnAP ID IE or the NG-RAN node1 UE XnAP ID IE or both, for which the NG-RAN node2 shall delete all the context information related to the NG-RAN node1 and release the corresponding resources. After completion of release of the resources, the NG-RAN node2 shall respond with the RESET RESPONSE message indicating the UE contexts admitted to be released. The NG-RAN node2 receiving the request for partial reset does not need to wait for the release or reconfiguration of radio resources to be completed before returning the RESET RESPONSE message. The NG-RAN node2 receiving the request for partial reset shall include in the RESET RESPONSE message, for each UE association to be released, the same list of UE-associated logical Xn-connections over Xn. The list shall be in the same order as received in the RESET REQUEST message and shall include also unknown UE-associated logical Xn-connections. If case of network sharing with multiple cell ID broadcast with shared Xn-C signalling transport, as specified in TS 38.300 [9], the RESET REQUEST message and the RESET RESPONSE message shall include the Interface Instance Indication IE to identify the corresponding interface instance. Interactions with other procedures: If the RESET REQUEST message indicates full reset, the NG-RAN node2 shall abort any other ongoing procedure (except for a Reset procedures). If the RESET REQUEST message indicates partial reset, the NG-RAN node2 shall abort any other ongoing procedure (except for a Reset procedures) on the same Xn interface related to a UE associated signalling connection indicated in the RESET REQUEST message. 8.4.4.3 Unsuccessful Operation Void. 8.4.4.4 Abnormal Conditions If the RESET REQUEST message is received, any other ongoing procedure (except another Reset procedure) on the same Xn interface shall be aborted. If the Reset procedure is ongoing and the responding node receives the RESET REQUEST message from the peer entity on the same Xn interface, it shall respond with the RESET RESPONSE message as specified in 8.4.4.2. If the initiating node does not receive the RESET RESPONSE message, the initiating node may reinitiate the Reset procedure towards the same NG-RAN node, provided that the content of the new RESET REQUEST message is identical to the content of the previously unacknowledged RESET REQUEST message. 8.4.5 Error Indication 8.4.5.1 General The Error Indication procedure is initiated by an NG-RAN node to report detected errors in one incoming message, provided they cannot be reported by an appropriate failure message. If the error situation arises due to reception of a message utilising UE associated signalling, then the Error Indication procedure uses UE-associated signalling. Otherwise the procedure uses non UE-associated signalling. 8.4.5.2 Successful Operation Figure 8.4.5.2-1: Error Indication, successful operation. When the conditions defined in clause 10 are fulfilled, the Error Indication procedure is initiated by the ERROR INDICATION message sent from the node detecting the error situation. The ERROR INDICATION message shall contain at least either the Cause IE or the Criticality Diagnostics IE. In case the Error Indication procedure is triggered by UE associated signalling, in the course of handover signalling and signalling for dual connectivity, the Old NG-RAN node UE XnAP ID IE and the New NG-RAN node UE XnAP ID IE shall be included in the ERROR INDICATION message. If any of the Old NG-RAN node UE XnAP ID IE and the New NG-RAN node UE XnAP ID IE is not correct, the cause shall be set to an appropriate value. If case of network sharing with multiple cell ID broadcast with shared Xn-C signalling transport, as specified in TS 38.300 [9], the ERROR INDICATION message shall include the Interface Instance Indication IE to identify the corresponding interface instance. 8.4.5.3 Unsuccessful Operation Not applicable. 8.4.5.4 Abnormal Conditions Void. 8.4.6 Xn Removal 8.4.6.1 General The purpose of the Xn Removal procedure is to remove the interface instance between two NG-RAN nodes in a controlled manner. If successful, this procedure erases any existing application level configuration data in the two nodes. NOTE: In case the signalling transport is shared among several Xn-C interface instances, and the TNL association is still used by one or more Xn-C interface instances, the initiating NG-RAN node should not initiate the removal of the TNL association. The procedure uses non UE-associated signaling. 8.4.6.2 Successful Operation Figure 8.4.6.2-1: Xn Removal, successful operation An NG-RAN node1 initiates the procedure by sending the XN REMOVAL REQUEST message to a candidate NG-RAN node2. Upon reception of the XN REMOVAL REQUEST message the candidate NG-RAN node2 shall reply with the XN REMOVAL RESPONSE message. After receiving the XN REMOVAL RESPONSE message, the initiating NG-RAN node1 shall initiate removal of the TNL association towards NG-RAN node2 and may remove all resources associated with that interface instance. The candidate NG-RAN node2 may then remove all resources associated with that interface instance. If the Xn Removal Threshold IE is included in the XN REMOVAL REQUEST message, the candidate NG-RAN node2 shall, if supported, accept to remove the interface instance with NG-RAN node1 if the Xn Benefit Value of the interface instance determined at the candidate NG-RAN node2 is lower than the value of the Xn Removal Threshold IE. If case of network sharing with multiple cell ID broadcast with shared Xn-C signalling transport, as specified in TS 38.300 [9], the XN REMOVAL REQUEST message and the XN REMOVAL RESPONSE message shall include the Interface Instance Indication IE to identify the corresponding interface instance. 8.4.6.3 Unsuccessful Operation Figure 8.4.6.3-1: Xn Removal, unsuccessful operation If the candidate NG-RAN node2 cannot accept to remove the interface instance with NG-RAN node1 it shall respond with an XN REMOVAL FAILURE message with an appropriate cause value. If case of network sharing with multiple cell ID broadcast with shared Xn-C signalling transport, as specified in TS 38.300 [9], the XN REMOVAL REQUEST message and the XN REMOVAL FAILURE message shall include the Interface Instance Indication IE to identify the corresponding interface instance. 8.4.6.4 Abnormal Conditions Void. 8.4.7 Failure Indication 8.4.7.1 General The purpose of the Failure Indication procedure is to transfer information regarding RRC re-establishment attempts, or received RLF Reports, between NG-RAN nodes. The signalling takes place from the NG-RAN node at which a re-establishment attempt is made, or an RLF Report is received, to an NG-RAN node to which the UE concerned may have previously been attached prior to the connection failure. This may aid the detection of radio link failure, handover failure cases. The procedure uses non UE-associated signalling. 8.4.7.2 Successful Operation Figure 8.4.7.2-1: Failure Indication, successful operation NG-RAN node2 initiates the procedure by sending the FAILURE INDICATION message to NG-RAN node1, following a re-establishment attempt or an RLF Report reception from a UE at NG-RAN node2, when NG-RAN node2 considers that the UE may have previously suffered a connection failure at a cell controlled by NG-RAN node1. If the UE RLF Report Container IE is included in the FAILURE INDICATION message, NG-RAN node1 shall use it to derive failure case information. 8.4.7.3 Unsuccessful Operation Not applicable. 8.4.7.4 Abnormal Conditions Void. 8.4.8 Handover Report 8.4.8.1 General The purpose of the Handover Report procedure is to transfer mobility related information between NG-RAN nodes. The procedure uses non UE-associated signalling. 8.4.8.2 Successful Operation Figure 8.4.8.2-1: Handover Report, successful operation NG-RAN node1 initiates the procedure by sending the HANDOVER REPORT message to NG-RAN node2. When receiving the message NG-RAN node2 shall assume that a mobility-related problem was detected. If the Handover Report Type IE is set to "HO too early" or "HO to wrong cell", then NG-RAN node1 indicates to NG-RAN node2 that, following a successful handover from a cell of NG-RAN node2 to a cell of NG-RAN node1, a radio link failure occurred and the UE attempted RRC Re-establishment or re-connected either at the original cell of NG-RAN node2 (Handover Too Early), or at another cell (Handover to Wrong Cell). The detection of Handover Too Early and Handover to Wrong Cell events is made according to TS 38.300 [9]. The HANDOVER REPORT message may include: - the Mobility Information IE, if the Mobility Information IE was sent for this handover from NG-RAN node2; - the Source cell C-RNTI IE. If received, NG-RAN node2 uses the above information according to TS 38.300 [9]. If the Handover Report Type IE is set to "Inter-system ping-pong", then NG-RAN node2 shall deduce that a completed handover from a cell of NG-RAN node2 to a cell in another system might have resulted in an inter-system ping-pong and the UE was successfully handed over to a cell of NG-RAN node1 (indicated with Target cell CGI IE). Interaction with the Failure Indication procedure: If NG-RAN node1 receives a UE RLF Report from an NG-RAN node via the FAILURE INDICATION message, as described in TS 38.300 [9], NG-RAN node1 may also include it in the UE RLF Report Container IE included in the HANDOVER REPORT message. 8.4.8.3 Unsuccessful Operation Not applicable. 8.4.8.4 Abnormal Conditions Void. 8.4.9 Mobility Settings Change 8.4.9.1 General This procedure enables an NG-RAN node to negotiate the handover trigger settings with a peer NG-RAN node controlling neighbouring cells. The procedure uses non UE-associated signalling. 8.4.9.2 Successful Operation Figure 8.4.9.2-1: Mobility Settings Change, successful operation NG-RAN node1 initiates the procedure by sending the MOBILITY CHANGE REQUEST message to NG-RAN node2. Upon receipt, NG-RAN node2 shall evaluate if the proposed NG-RAN node2 handover trigger modification may be accepted. If NG-RAN node2 is able to successfully complete the request it shall reply with MOBILITY CHANGE ACKNOWLEDGE message. 8.4.9.3 Unsuccessful Operation Figure 8.4.9.3-1: Mobility Settings Change, unsuccessful operation If the requested parameter modification is refused by NG-RAN node2, or if NG-RAN node2 is not able to complete the procedure, NG-RAN node2 shall send the MOBILITY CHANGE FAILURE message with the Cause IE set to an appropriate value. NG-RAN node2 may include the Mobility Parameters Modification Range IE in the MOBILITY CHANGE FAILURE message, for example in cases when the proposed change is out of the permitted range. 8.4.9.4 Abnormal Conditions Void. 8.4.10 Resource Status Reporting Initiation 8.4.10.1 General This procedure is used by an NG-RAN node to request the reporting of load measurements to another NG-RAN node. The procedure uses non UE-associated signalling. 8.4.10.2 Successful Operation Figure 8.4.10.2-1: Resource Status Reporting Initiation, successful operation NG-RAN node1 initiates the procedure by sending the RESOURCE STATUS REQUEST message to NG-RAN node2 to start a measurement, stop a measurement or add cells to report for a measurement. Upon receipt, NG-RAN node2: - shall initiate the requested measurement according to the parameters given in the request in case the Registration Request IE set to "start"; or - shall stop all cells measurements and terminate the reporting in case the Registration Request IE is set to "stop"; or - shall add cells indicated in the Cell To Report List IE to the measurements initiated before for the given measurement IDs, in case the Registration Request IE is set to "add". If measurements are already initiated for a cell indicated in the Cell To Report List IE, this information shall be ignored. If the Registration Request IE is set to "start" in the RESOURCE STATUS REQUEST message and the Report Characteristics IE indicates cell specific measurements, the Cell To Report List IE shall be included. If Registration Request IE is set to "add" in the RESOURCE STATUS REQUEST message, the Cell To Report List IE shall be included. If NG-RAN node2 is capable to provide all requested resource status information, it shall initiate the measurement as requested by NG-RAN node1 and respond with the RESOURCE STATUS RESPONSE message. Interaction with other procedures When starting a measurement, the Report Characteristics IE in the RESOURCE STATUS REQUEST indicates the type of objects NG-RAN node2 shall perform measurements on. For each cell, NG-RAN node2 shall include in the RESOURCE STATUS UPDATE message: - the Radio Resource Status IE, if the first bit, "PRB Periodic" of the Report Characteristics IE included in the RESOURCE STATUS REQUEST message is set to "1". If NG-RAN node2 is a gNB and if the cell for which Radio Resource Status IE is requested to be reported supports more than one SSB, the Radio Resource Status IE for such cell shall include the SSB Area Radio Resource Status Item IE for all SSB areas supported by the cell. If the SSB To Report List IE is included for a cell, the Radio Resource Status IE for such cell shall include the requested SSB Area Radio Resource Status List IE; - the TNL Capacity Indicator IE, if the second bit, "TNL Capacity Ind Periodic" of the Report Characteristics IE included in the RESOURCE STATUS REQUEST message is set to "1". The received TNL Capacity Indicator IE represents the lowest TNL capacity available for the cell. - the Composite Available Capacity Group IE, if the third bit, "Composite Available Capacity Periodic" of the Report Characteristics IE included in the RESOURCE STATUS REQUEST message is set to "1". If the Cell Capacity Class Value IE is included within the Composite Available Capacity Group IE, this IE is used to assign weights to the available capacity indicated in the Capacity Value IE. If NG-RAN node2 is a gNB and if the cell for which Composite Available Capacity Group IE is requested to be reported supports more than one SSB, the Composite Available Capacity Group IE for such cell shall include the SSB Area Capacity Value List for all SSB areas supported by the cell, providing the SSB area capacity with respect to the Cell Capacity Class Value. If the SSB To Report List IE is included for a cell, the Composite Available Capacity Group IE for such cell shall include the requested SSB Area Capacity Value List IE. If the cell for which Composite Available Capacity Group IE is requested to be reported supports more than one slice, and if the Slice To Report List IE is included for a cell, the Slice Available Capacity IE for such cell shall include the requested Slice Available Capacity Value Downlink IE and Slice Available Capacity Value Uplink IE, providing the slice capacity with respect to the Cell Capacity Class Value. - the Number of Active UEs IE, if the fourth bit, "Number of Active UEs" of the Report Characteristics IE included in the RESOURCE STATUS REQUEST message is set to "1"; - the RRC Connections IE, if the fifth bit, "RRC Connections" of the Report Characteristics IE included in the RESOURCE STATUS REQUEST message is set to "1". If the Reporting Periodicity IE in the RESOURCE STATUS REQUEST is present, this indicates the periodicity for the reporting of periodic measurements. the NG-RAN node2 shall report only once, unless otherwise requested within the Reporting Periodicity IE. 8.4.10.3 Unsuccessful Operation Figure 8.4.10.3-1: Resource Status Reporting Initiation, unsuccessful operation If any of the requested measurements cannot be initiated, NG-RAN node2 shall send the RESOURCE STATUS FAILURE message with an appropriate cause value. 8.4.10.4 Abnormal Conditions For the same Measurement ID, if the initiating NG-RAN node1 does not receive either the RESOURCE STATUS RESPONSE message or the RESOURCE STATUS FAILURE message, the NG-RAN node1 may reinitiate the Resource Status Reporting Initiation procedure towards the same NG-RAN node, provided that the content of the new RESOURCE STATUS REQUEST message is identical to the content of the previously unacknowledged RESOURCE STATUS REQUEST message. If the NG-RAN node2 receives a RESOURCE STATUS REQUEST message which includes the Registration Request IE set to "add" or "stop" and if the NG-RAN node2 Measurement ID value received in the RESOURCE STATUS REQUEST message is not used, the NG-RAN node2 shall initiate RESOURCE STATUS FAILURE message with an appropriate cause value. If the Report Characteristics IE bitmap is set to "0" (all bits are set to "0") in the RESOURCE STATUS REQUEST message then NG-RAN node2 shall initiate a RESOURCE STATUS FAILURE message with an appropriate cause value. If the NG-RAN node2 receives a RESOURCE STATUS REQUEST message which includes the Registration Request IE set to "start" and the NG-RAN node1Measurement ID IE corresponding to an existing on-going load measurement reporting, then NG-RAN node2 shall initiate a RESOURCE STATUS FAILURE message with an appropriate cause value. 8.4.11 Resource Status Reporting 8.4.11.1 General This procedure is initiated by an NG-RAN node to report the result of measurements admitted by the NG-RAN node following a successful Resource Status Reporting Initiation procedure. The procedure uses non UE-associated signalling. 8.4.11.2 Successful Operation Figure 8.4.11.2-1: Resource Status Reporting, successful operation NG-RAN node2 shall report the results of the admitted measurements in RESOURCE STATUS UPDATE message. The admitted measurements are the measurements that were successfully initiated during the preceding Resource Status Reporting Initiation procedure. 8.4.11.3 Unsuccessful Operation Not applicable. 8.4.11.4 Abnormal Conditions Void 8.4.12 Access And Mobility Indication 8.4.12.1 General The purpose of the Access and Mobility Indication procedure is to transfer Access and Mobility related information between NG-RAN nodes. 8.4.12.2 Successful Operation Figure 8.2.12.2-1: Access And Mobility Indication.

X.680 [16] and ITU-T Rec. X.681 [17]. Sub clause 9.3 presents the Abstract Syntax of the XnAP protocol with ASN.1. In case there is contradiction between the ASN.1 definition in this sub clause and the tabular format in sub clause 9.1 and 9.2, the ASN.1 shall take precedence, except for the definition of conditions for the presence of conditional elements, in which the tabular format shall take precedence. The ASN.1 definition specifies the structure and content of XnAP messages. XnAP messages can contain any IEs specified in the object set definitions for that message without the order or number of occurrence being restricted by ASN.1. However, for this version of the standard, a sending entity shall construct an XnAP message according to the PDU definitions module and with the following additional rules: - IEs shall be ordered (in an IE container) in the order they appear in object set definitions. - Object set definitions specify how many times IEs may appear. An IE shall appear exactly once if the presence field in an object has value "mandatory". An IE may appear at most once if the presence field in an object has value "optional" or "conditional". If in a tabular format there is multiplicity specified for an IE (i.e. an IE list) then in the corresponding ASN.1 definition the list definition is separated into two parts. The first part defines an IE container list in which the list elements reside. The second part defines list elements. The IE container list appears as an IE of its own. For this version of the standard an IE container list may contain only one kind of list elements. NOTE: In the above, "IE" means an IE in the object set with an explicit ID. If one IE needs to appear more than once in one object set, then the different occurrences have different IE IDs. If an XnAP message that is not constructed as defined above is received, this shall be considered as Abstract Syntax Error, and the message shall be handled as defined for Abstract Syntax Error in clause 10. 9.3.2 Usage of Private Message Mechanism for Non-standard Use The private message mechanism for non-standard use may be used: - for special operator (and/or vendor) specific features considered not to be part of the basic functionality, i.e. the functionality required for a complete and high-quality specification in order to guarantee multivendor inter-operability. - by vendors for research purposes, e.g. to implement and evaluate new algorithms/features before such features are proposed for standardisation. The private message mechanism shall not be used for basic functionality. Such functionality shall be standardised. 9.3.3 Elementary Procedure Definitions -- ASN1START -- ************************************************************** -- -- Elementary Procedure definitions
