SGW Access Peer Profile Configuration Mode Commands
This configuration mode enables operators to configure a peer profile for the Network Triggered Service Restoration
feature.
feature.
MME restoration is a 3GPP specification-based feature designed to gracefully handle the sessions at S-GW once S-GW
detects that the MME has failed or restarted. If the S-GW detects an MME failure based on a different restart counter in
the Recovery IE in any GTP Signaling message or Echo Request / Response, it will terminate sessions and not maintain
any PDN connections.
detects that the MME has failed or restarted. If the S-GW detects an MME failure based on a different restart counter in
the Recovery IE in any GTP Signaling message or Echo Request / Response, it will terminate sessions and not maintain
any PDN connections.
As a part of this feature, if a S-GW detects that a MME or S4-SGSN has restarted, instead of removing all the resources
associated with the peer node, the S-GW shall maintain the PDN connection table data and MM bearer contexts for
some specific S5/S8 bearer contexts eligible for network initiated service restoration, and initiate the deletion of the
resources associated with all the other S5/S8 bearers.
