Harald Welte 77847ad020 add copyright statement and AGPLv3 headers to source code files 2015-10-06 22:07:04 +02:00
Harald Welte 6286880caa the Context ID is a 24bit number, we cannot use len = 4 bytes! 2015-09-18 01:23:55 +02:00
Harald Welte 1c2ada0e7f ranap: receive/parse DirectTransfer 2015-09-11 20:10:17 +02:00
Harald Welte 80401adcb0 ranap: Parse InitialUE message and hex-print NAS PDU 2015-09-11 19:48:06 +02:00
Harald Welte 0f0ea8112f RUA: hand off RANAP from all PDU types, not just UnitDataTransfer 
Also, we now offer a ranap_tx_dt() message for connection-oriented
RANAP transfers.  A far as I understand the RUA spec, on RUA layer,
all operations are Class 2, i.e. without any response/confirmation.

Harald Welte cc27bebd30 ranap: prepare decoding of InitialUE message 2015-09-11 18:45:39 +02:00

Harald Welte 208b7b0778 iu_helpers: fix encoding of BCD (like IMSI) into OCTET STING 2015-09-11 17:35:52 +02:00
Harald Welte 393f2bd9fb move BCD string encoding/decoding functions to iu_helpers.[ch] 2015-09-11 17:13:51 +02:00
Harald Welte 3af1db87ed hnbap: Print error messages in error cases 2015-09-11 17:03:16 +02:00
Harald Welte 10dfc5a97d respond to HNBAP UE REGISTER REQ withe correspnding ACCEPT 
The Accept incudes the IMSI that the phone presented, but
somehow we fail to encode the Context ID as bitstring,  see
../pcap/20150911-hnbap-ue_register.pcap

Harald Welte 256c67ad81 ue context: fix linked list insert 2015-09-11 01:22:29 +02:00
Harald Welte 6289cc6248 remove obsolete asn1c makefiles in the asn1c/ hierarchy 
we are generating the code locally in src/{ranap,rua,hnbap}
 2015-09-11 00:17:07 +02:00
Harald Welte b534e5c085 introduce ue_context management 
We keep one 'ue_context' structure for every UE that we see
a UE REGISTER REQUEST for.

Harald Welte e2e5d4dd53 Back RUA/RANAP integration until RANAP Reset works for cs+ps 
The hNodeB is now actively transmitting and we are getting up to the
HNBAP UE-REGISTER.req with the IMSI of the MS.
 2015-09-10 23:49:45 +02:00
Harald Welte 350814a5cb first dispatch of RUA into RANAP 
This is becoming more and more of a hack, as asn1c + asn1tostruct.py
don't really deal well with the RANAP syntax :(
 2015-09-10 22:32:15 +02:00
Harald Welte ac9c024432 ranap: Add more manual definitions to RANAP-PDUs 
It seems that individual IEs contain nested containers, and
asn1c is not generating code for that unless we help it by some
hand-crafted additional definitions. *sigh*
 2015-09-10 21:18:16 +02:00
Harald Welte 68fcff219f don't attempt to regenerate ranap-common, it is not auto generated! 2015-09-10 19:35:09 +02:00
Harald Welte 64b4ebe57c rua: dispatch different message types and print context/cause 2015-09-10 19:29:59 +02:00

Harald Welte 84839c04ea asn1tostruct.py: Add support for type prefixing 
If asn1c generates prefixed type names, the asn1tostruct.py of course
also needs to be modified to do so.

Harald Welte 2204f9d43d hnbgw: zero-initialize the output struct before aper_decode() 
asn1c has this strange behavior that the _output_ struct must be
zero-initialized.
 2015-09-07 22:25:35 +02:00
Harald Welte 5c11c94637 hnbgw: Fix SCTP server/receiver 
* we need to swap PPID endianness

Harald Welte 0bdea4da55 Makefile: chrdir to asn1c subdir and build library there 2015-08-30 23:13:06 +02:00
Harald Welte d523a69dbe import ans1c generated C sources for HNBAP 
TODO: split the HNBAP specific code from the core runtime code
and use libosmo-asn1c instead.  This is required as we will be
dealing with multiple ASN.1 data formats from within a single
executable.
