=== Gb/NS configuration
|
|
|
|
This section describes the configuration that libosmogb exposes via the
|
|
VTY and is valid for OsmoSGSN and OsmoGbProxy.
|
|
|
|
==== Gb over Frame Relay over E1/T1
|
|
|
|
The Gb over Frame Relay over E1/T1 requires:
|
|
|
|
* a hdlc interface
|
|
* a frame relay role (fr or frnet)
|
|
* the DLCI
|
|
|
|

==== Gb over IP "ip.access style"
|
|
|
|
The Gb over IP "ip.access style" can be used with a dynamic configuration or with a
|
|
static configuration
|
|
|
|
The static configuration requires to configure all endpoints on the BSS and SGSN.
|
|
In constrast the dynamic configuration allows the SGSN to have only a reduced configuration.
|
|
|
|
===== Gb over IP "ip.access style" dynamic configuration
|
|
|
|
.Example: Gb over IP/UDP ip.access style dynamic configuration (SGSN)
|
|
----
|
|
ns
|
|
bind udp ran1 <1>
|
|
listen 10.100.1.1 23000 <2>
|
|
accept-ipaccess <3>
|
|
----
|
|
<1> create a IP/UDP bind with name ran1
|
|
<2> bind to 10.100.1.1:23000
|
|
<3> accept unknown BSS of ip.access style
|
|
|
|
.Example: Gb over IP/UDP "ip.access style" dynamic configuration (GbProxy as BSS)
|
|
----
|
|
ns
|
|

|
|

<1> create a IP/UDP bind with name ran1
|
|
<2> bind to 10.100.1.1:23000
|
|
<3> accept unknown BSS of ip.access style
|
|
|
|
NOTE: The OsmoPCU supports ip.access style Gb/NS but doesn't support this vty configuration because
|
|
it's receiving the configuration from the BTS/BSC.

|
it's receiving the configuration from the BTS/BSC.

==== Gb over IP 3GPP static configuration
|
|
|
|
A static IP/UDP configuration without SNS as specified by 3GPP 48.016.
|
|
|
|
.Example: Gb over IP/UDP static configuration BSS/SGSN
|

|
|
<3> add NSE 1001 with 2 NSVC
|
|
<4> short configuration with default signalling and data weight of 1
|
|
|
|
==== Gb over IP 3GPP auto configuration as BSS
|
|
|
|
IP/UDP auto-configuration with initial endpoints to an SGSN.
|
|
The auto-configuration will use the first bind to connect to the
|
|
first endpoint. If this fails Osmocom will iterate over all endpoints and binds to find
|
|
a working combination.
|
