Message transmission method and equipment

Abstract

The invention discloses a message transmission method and equipment. The realization of the method comprises the following steps: AMF receives a first message from terminal equipment; the first message carries a second message sending to at least one third-party equipment, the third-party equipment is the network equipment except the terminal equipment and the AMF; the first message carries a first parameter, the second message carries a second parameter, the first parameter is used for identifying the first message, and the second parameter is used for identifying the second message; the second message is sent to the third-party equipment, the second message carries the second parameter. The terminal equipment respectively identifies the first message and the second message by using two layer of parameters; for the AMF and the third-party equipment, the terminal equipment still can distinguish the first message and the second message under the condition of sending multiple messages having the same type of the first message, thereby avoiding disorder.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message transmission method and equipment. Background technique [0002] In order to meet the challenges of wireless broadband technology and maintain the leading edge of the Third Generation Partnership Project (3GPP) network, the 3GPP standard group formulated the next generation mobile communication network architecture (Next Generation System), called the fifth generation mobile Communication technology (5th-Generation, 5G) network architecture. This architecture not only supports the wireless technology defined by the 3GPP standard group to access the 5G Core network (5G Core network), but also supports the non-3GPP (non-3GPP) access technology through the non-3GPP conversion function (non-3GPP Interworking Function, N3IWF) or The next generation access gateway (next Generation packet data Gateway, ngPDG) accesses the 5G core network. The wireless technolo...

Problems solved by technology

[0005] However, the current communication protocol mechanism does not provide a solution for AMF and SMF to distinguish NAS request messages and SM messages respectively, resulting in the case where a terminal device sends multiple NAS request messages, AMF and SMF cannot distinguish these messages; further, AMF After sending a reply message with the SMF, the UE side cannot identify which NAS request message the reply message is for

Therefore, the current communication protocol will cause confusion when the UE sends multiple NAS request messages
