Patent ID: 11553545

Abstract:
A method for session method, a terminal device and a network device are provided. The method includes: sending, by a terminal device, first information to a first network device, wherein the first indication is used for requesting for establishing a packet data network (PDN) connection; receiving, by the terminal device, second information from the network device, wherein the second information indicates that the request, initiated by the terminal device, for establishing the PDN connection is accepted, the second information includes first indication information for indicating whether a protocol data unit (PDU) session corresponding to the PDN connection supports multi-access (MA) after the terminal devices moves from a 4th-generation (4G) network to a 5th-generation (5G) network, and the PDU session, if supporting the MA, is able to implement data transmission with a 3rd generation partnership project (3GPP) network and a non-3GPP network simultaneously.
