GGSN Enhancements for 16.0 ▀
Release Change Reference, StarOS Release 16 ▄
149
Below are the set of steps that can be carried out to gracefully clean up VoLTE PDNs on a node:
1. Use call identification configuration to configure the VoLTE APN to do the VoLTE PDN and bearer
identification.
2. Using the new call-policy configuration, configure the node to reject any new calls coming on the node, so that
these new calls get directed to an alternate PDN.
3. Using the
clear subscribers
CLI with
non-volte-call
qualifier in it, initiate the clean up of PDNs that
don’t have any Active Voice bearer.
4. Wait for some time and execute the
clear subscribers
CLI again to clean up any non-active VoLTE PDNs.
Repeat this step until all of the VoLTE PDNs are cleaned up.
Further enhancements are planned for this feature in future releases.
Customer Impact: Several features added for VoLTE in 16.0 will provide a lot of value to Operators; they help
Operator in providing high quality VoLTE service to ensure better user experience for VoLTE service users.
