Configuring the SGSN Pooling feature
2G-SGSN pool configuration
Listed below are the pre-requisite CLI configurations that should be enabled to configure a 2G SGSN Pool:
1. 2G SGSN Pooling configuration is done under the GPRS service in the Gb context.
2. The NRI value, NRI length, Null-NRI value and non-broadcast LAC/RAC are configured for the GPRS service.
3. The GPRS service is capable of handling both pooled and non-pooled BSCs.
GPRS Service Configuration:
config
context <context_name>
gprs-service <service_name>
peer-nsei <nse_id> pooled
nri length nri_length { nri-value nri_value | null-nri-value null_nri_value non
broadcast-lac lac_id rac rac_id [ nri-value value ]}
broadcast-lac lac_id rac rac_id [ nri-value value ]}
exit
Notes:
The above configuration must be repeated each time a BSC is added.
The command
peer-nsei
is used to render a BSC as pooled or non-pooled.
