SGSN Features in Release 8.0

1-51

In Release 8.0, the SGSN now supports the Gs interface to the MSC/VLR. This interface is 
vital in the call-setup process as these databases provide authentication information about 
MS/UEs attempting to attach.

The Gs Service Configuration Mode has been added to configure and manage the Gs 
interface between the SGSN and the MSC/VLR. This new mode includes the following 
commands:

- associate-sccp-network 
- bssap+ 
- default 
- end
- exit 
- max-retransmission
- non-pool-area
- pool-area
- timeout
- vlr

The new commands will be found the chapter titled Gs Service Configuration Mode 
Commands in the Command Line Interface Reference.

A new command has been created to enable the operator to further control message length 
by configuring the number of 

 sent in each SGSN Init Reset Resource message.

This change will have no impact on current or future configurations as the previously coded 
system value was 250.

Refer to the RNC Configuration Mode chapter of the Command Line Interface Reference for 
additional information.

The operator can configure a cap or limit for the QoS bit rate.

The SGSN can now be configured to cap the QoS bit rate parameter when the subscribed 
QoS provided by the HLR is lower than the locally configured value.

Depending upon the keywords included in the command, the SGSN can: take the QoS 
parameter configuration from the HLR configuration. take the QoS parameter configuration 
from the local settings for use in the APN policy. during session establishment, apply the 
lower of either the HLR subscription or the locally configured values.

Refer to the SGSN APN Policy Configuration Mode chapter of the Command Line Interface 
Reference for the qos command.
