Release

In MME, handling of Duplicate eNodeB Path support is introduced.

21.28.m0

Feature Changes

Previous Behavior: When a duplicate eNodeB path is detected, mmedemux retains the old stale path and deletes the new path.

New Behavior: Enable the delete-old-on-duplicate-enodeb-detection CLI under mme-service to control the duplicate eNodeB path. When a duplicate eNodeB path is detected, mmedemux deletes the old stale path, and allows the new path to get established.


Note
The delete-old-on-duplicate-enodeb-detection CLI is a critical parameter, which will restart the mme service and remove active sessions.

Command Changes

Use the following commands to configure the MME to delete an old eNodeB path and retain a new eNodeB path while detecting duplicate eNodeB id. 


configure  
   context context_name   
         mme-service service_name    
         [ no ] delete-old-on-duplicate-enodeb-detection 
         exit  
      exit

NOTES:

  • delete-old-on-duplicate-enodeb-detection : The mmedemux deletes the old stale path and establishes a new path. By default it is disabled.


    Note
