Feature Description

When the IMS PDN sgw-service and smf-service selected for a subscriber are on the same cluster and same RACK, the following message flow occurs when sgw-service sends a message to smf-service:

  • The message is sent from S5e gtpc-ep interface to network interface.

  • The message returns to the S5 interface from gtpc-ep to smf-service.

For the subscribers that are collocated, the communication happens between the sgw-service and the smf-service. This approach reduces the processing load on the gtpc-ep.

Note

A direct communication between sgw-service and smf-service is not supported to transfer messages on monitor protocol and monitor subscriber.
