Addressing method, communication device and system

Abstract

Disclosed are an addressing method, a communication device and a system, which relate to the field of communications, and can route an NAS signaling of a terminal device to a local control plane network element, avoid an excessively roundabout signaling transmission path, and reduce the time delay of a local service request flow of the terminal device. The method comprises the following steps: anaccess mobility management function network element receives first information sent by wireless access network equipment from a terminal device; wherein the first information is used for requesting toestablish a session of a local service for the terminal device; an access mobility management function network element determines that the terminal device establishes a local service; and the networkelement with the access mobility management function sends second information to the wireless access network equipment, the second information comprises a first address, and the first address pointsto the first network element.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to an addressing method, a communication device, and a system. Background technique [0002] In the 5G communication system, by deploying a mobile edge computing (MEC) platform close to the user's access point, operators and third parties can achieve efficient service distribution by reducing delay and load. example, such as figure 1 As shown, the session management function (session management function, SMF) network element and the access mobility management function (access and mobility management function, AMF) network element are all deployed in a higher position in the network, and the radio access network (radio Access network (RAN) equipment and user plane function (userplane function, UPF) network elements are deployed locally. refer to figure 1 , when the terminal device initiates a service request process related to the MEC service, the service...

Problems solved by technology

However, since the RAN does not perceive the existence of the local control plane network element, when the RAN receives the non-access stratum (non-access stratum, NAS) signaling from the terminal device, the RAN still routes the NAS signaling to the AMF, so that The signaling transmission path is relatively circuitous, so how the RAN routes the NAS signaling of the terminal device to the local control plane is an urgent problem to be solved
