Problems solved by technology

[0004] exist figure 1 In the scenario shown, the V2X server can communicate with multiple edge UPF entities. However, if the V2X server is sunk to the edge to form a local V2X server, then a local V2X server can only communicate with the edge UPF entity corresponding to the local V2X server, but with Other edge UPF entities cannot communicate with each other, which will increase the delay of network communication

Abstract

The invention relates to a message multicast and message broadcast method and device, which are used for reducing time delay. The message multicast method comprises the steps that a CPF entity receives a multicast group joining request, wherein the multicast group joining request is used for a first terminal device to request to join a multicast group indicated by a multicast address; The CPF entity adds the terminal equipment into the multicast group; The CPF entity generates a multicast forwarding route of which a destination address is the multicast address; And the CPF entity sends the multicast forwarding route to at least one UPF entity, wherein the at least one UPF entity comprises UPF entities where all terminal devices included in the multicast group are located.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message multicast and message broadcast method and device. Background technique [0002] Please refer to figure 1 , currently provides a scenario for the vehicle to everything (V2X) communication method. Among them, the user plane function (UPF) entity of the core network that sinks to the edge has multimedia broadcast and multicast services (MBMS) capabilities, and can be used as an edge gateway (local gateway, local GW) and The base station communicates, and the UPF entity can also communicate with a core network control plane function (control plane function, CPF) entity. In addition, multiple UPF entities can communicate with a V2X server (V2X server). [0003] The core requirement brought by V2X communication to the network is low service latency. figure 1 In the scenario shown, the V2X server needs to process messages from multiple UPF entities, a...
