Notes:
ip_address
is an IPv4 or IPv6 address for the S11 interface of the co-located S-GW.
The S-GW address configured in this command is the one which will always be used by the MME while in PS-
LTE network operation. An MME configured for PS-LTE network operation will not send any DNS queries
for S-GW or P-GW lookups; it will only use the S-GW configured in the CLI command for PS-LTE operation
and the PGW configured in the matching APN profile, regardless of any other configuration present. All intra-
MME S1 and X2 handovers and all TAU Requests with a local GUTI will be serviced by the same S-GW that
is configured for PS-LTE network operation with the P-GW(s) used at the time of the initial Attach or
relocation to the MME in question. S-GW relocation is neither necessary nor supported for intra-MME
handovers or intra-MME TAU Requests.

If this command is issued on an mme-service instance that is currently operating and that did not have PS-LTE
network operation previously configured, any UEs that were previously attached or relocated under normal
LTE network operation will continue to operate using normal LTE network behavior, rather than the PS-LTE
network behavior described in this document. All UEs that attach or relocate to this network after this
command is issued will operate using PS-LTE network behavior with the configured S-GW chosen for all new
calls.

ho-resource-release-timeout
This new command configures the timer that is started when the source MME initiates a handover. This command is
available for all MME services, regardless if the license for PS-LTE functionality is present.
