Abstract

The present disclosure relates to a multicast management method and device. The method includes: acquiring first terminal capability information of a first terminal; determining group management information of the terminal group according to the first terminal capability information; sending the group management information . Various aspects of the embodiments of the present disclosure can ensure that the terminal capability information used by all terminals in the terminal group can be updated in real time when a new terminal joins the terminal group or when the associated terminal is updated in capability, so that the information used by all the terminals can be updated in real time. The terminal capability is managed, and the embodiment of the present disclosure has the characteristics of simplicity and practicability, and can reduce signaling overhead while realizing the dynamic update of group management information.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a multicast management method and device. Background technique [0002] V2X (Vehicle to X, Internet of Vehicles) is the key technology of the future intelligent transportation system, mainly researching the vehicle data transmission scheme based on the 3GPP communication protocol. V2X communication includes V2V communication (Vehicle to Vehicle, vehicle-to-vehicle communication), V2I communication (Vehicle to Infrastructure, vehicle-to-roadside infrastructure communication), and V2P communication (Vehicle to People, vehicle-to-pedestrian communication). V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and in-vehicle entertainment information, etc. [0003] In the V2X communication system, when the related technologies exchange information in the V2X terminal group, the signaling overh...
