Abstract
Embodiments of the present disclosure provide methods and apparatus for indirect data forwarding. A method at a mobility management node comprises sending, to a serving gateway entity in the first system, a request for creating an indirect data forwarding tunnel. The request comprises an indication flag for indicating to the serving gateway entity that an indirect data forwarding tunnel is to be created with a user plane function entity in a second system. The method further comprises receiving a response for the request from the serving gateway entity.

A method performed by a mobility management node in a first system, the method comprising:
- sending, to a serving gateway entity in the first system, a request for creating an indirect data forwarding tunnel, wherein the request comprises an indication that an indirect data forwarding tunnel is to be created with a user plane function entity in a second system;
- and
- receiving a response to the request from the serving gateway entity.
A method performed by a serving gateway entity in a first system, comprising:
- receiving, from a mobility management node in the first system, a request for creating an indirect data forwarding tunnel, wherein the request comprises an indication that an indirect data forwarding tunnel is to be created with a user plane function entity in a second system;
- processing the request to generate a response for the request;
- and
- sending, to the mobility management node, the response generated for the request.
A mobility management node in a first system, the mobility management node comprising:
- a processor;
- and
- a memory operably coupled to the processor and containing instructions executable by said processor, whereby said mobility management node is operative to:
- send, to a serving gateway entity in the first system, a request for creating an indirect data forwarding tunnel, where the request comprises an indication that an indirect data forwarding tunnel is to be created with a user plane function entity in a second system;
- and
- receive a response to the request from the serving gateway entity.
