Procedure to Configure MS Offloading
The SGSN
offload
command is used to configure the MS offloading procedure.
The following CLI command (for phase 1 and phase 2 of offloading) is issued for each GPRS/SGSN service:
sgsn offload { gprs-service service_name | sgsn-service service_name } { activating [
imsi imsi | nri-value nri_value | stop [ imsi imsi | nri-value nri_value ] ] | connecting
[ nri-value nri_value | stop [ imsi imsi | nri-value nri_value | target-nri target_nri ]
| t3312-timeout seconds [ nri-value nri_value | target-nri target_nri ] | target-nri
target_nri [ imsi imsi | target-count num_to_offload ] }
imsi imsi | nri-value nri_value | stop [ imsi imsi | nri-value nri_value ] ] | connecting
[ nri-value nri_value | stop [ imsi imsi | nri-value nri_value | target-nri target_nri ]
| t3312-timeout seconds [ nri-value nri_value | target-nri target_nri ] | target-nri
target_nri [ imsi imsi | target-count num_to_offload ] }
Consider and SGSN node which was offloaded due to a maintenance requirement, once this SGSN is again operational
it will not recover the subscribers attached before the maintenance occurred. In due course this SGSN will be leveraged,
with subscribers moved from (partial offload) two or three most loaded SGSNs.
