Limiting 'network-feature-support-ie'
CSCux62899 - MME should not expand 'network-feature-support-ie ims-voice-over-ps'
Previous Behavior:
When the call-control profile's 'network-feature-support-ie ims-voice-over-ps' command was configured,
without including either the 'supported' or 'not-supported' keyword, the 'supported' keyword was appended
automatically. This resulted in the MME indicating network feature support in the Attach Accept sent to the
UE and adding the "Homogenous Support of IMS Voice over PS Sessions" AVP to the S6a
Update-Location-Request and Notify Request messages sent to the HSS, with the value set to "Supported".
This indicated that IMS Voice over PS was supported in all Tracking Areas.

When the call-control profile's 'network-feature-support-ie ims-voice-over-ps' command is configured, without

Paging Pre-Emption
CSCux40546 - MME higher paging precedence does not take over paging in progress
Feature Changes
Previous Behavior: By default, the MME does not support immediate paging pre-emption . The MME waits
until the current paging procedure times out and then picks the new precedence based on the paging precedence
configuration and then immediately sends another Paging Request.

configuration and then immediately sends another Paging Request.
New Behavior: While the default behavior has not changed, a new CLI makes it possible for the operator to
override the default behavior and enable an immediate paging pre-emption causing the MME to stop an
on-going paging procedure for any paging trigger and adopt a newly received paging trigger of higher paging
precedence.
