Abstract
Embodiments of the present disclosure provide method and apparatus for populating alternative PGW-C/SMF information. A performed by an access and mobility management function (AMF) in a first telecommunication system may include receiving alternative packet data network gateway control plane/Session Management Function (PGW-C/SMF) information from a first PGW-C/SMF or a second SMF. The method may further include sending the alternative PGW-C/SMF information to a mobility management entity, MME in a second telecommunication system.
Claims24
A method performed by an access and mobility management function, AMF, in a first telecommunication system, comprising:
- receiving alternative packet data network gateway control plane/Session Management Function, PGW-C/SMF, information from a first PGW-C/SMF or a second SMF;
- and
- sending the alternative PGW-C/SMF information to a mobility management entity, MME, in a second telecommunication system.
(canceled)
A method performed by a first PGW-C/SMF, comprising:
- establishing a PDU session for a User Equipment, UE;
- and
- sending alternative PGW-C/SMF information to a second SMF for the PDU session anchored at the first SMF+PGW-C or an access and mobility management function, AMF,
- wherein an alternative PGW-C/SMF will be selected based on the alternative PGW-C/SMF information in an event the first PGW-C/SMF has failed.

A first PGW-C/SMF, comprising:
- a processor;
- and
- a memory coupled to the processor, said memory containing instructions executable by said processor, whereby the first PGW-C/SMF is operative to:
- establish a PDU session for a User Equipment, UE;
- and
- send alternative PGW-C/SMF information to a second SMF for the PDU session anchored at the first SMF+PGW-C or an access and mobility management function, AMF;
- wherein an alternative PGW-C/SMF will be selected based on the alternative PGW-C/SMF information in an event the first PGW-C/SMF has failed.
