Configuration added to configure the MME to send old TAC Id in delete session request for old sessions.

21.28.m7

Feature Changes

Previous Behavior: While processing an Attach Over Attach Request, the MME sends a delete-session-request to the subscriber with the TAC Id received in Attach Request, as opposed to the last visited TAC Id.

New Behavior: A new CLI oldtac-dsr-attach-over-attach under mme-service is added to send old TAC Id in Delete Session Request. The subsequent Create Session Request is sent with the new TAC Id and the Detach Request Delete Session Request is sent with the new TAC Id received in the second attach.


Note

The oldtac-dsr-attach-over-attach CLI will configure the MME to send old TAC Id in delete session request for old sessions in attach over attach scenario.

Command Changes

Use the following commands to configure the MME to send the old TAC Id in Delete Session Request for old sessions in attach over attach scenario. 


configure  
   context context_name   
         mme-service service_name    
         [ no ] oldtac-dsr-attach-over-attach 
         exit  
      exit

NOTES:

  • oldtac-dsr-attach-over-attach : Sends old TAC Id in Delete Session Request for old sessions in attach over attach scenario. By default, it is disabled.

  • no : Disables the CLI oldtac-dsr-attach-over-attach.
