SYSTEM AND METHOD FOR ENABLING SESSION CONTEXT CONTINUITY OF LOCAL SERVICE AVAILABILITY IN LOCAL CELLULAR COVERAGE

摘要

A method for use in a mobility management entity of a network in which simultaneous use of multiple serving gateways is supported, the method comprising: receiving a request for a handover (28-1); sending a request to create a session context to a target serving gateway (28-2); receiving a response that includes information to enable creation of the session context (28-3); sending a request to delete a session context of local connectivity with a local serving gateway (28-4); receiving a response that indicates that the session context of local connectivity has been deleted (28-5); sending a request to forward relocation of one or more PDP contexts or PDN connections to be handed over (28-6).
