A method, device and system for terminal device to switch multicast service

Abstract

The invention provides a method for a terminal equipment switching multicast service, a device and a system, comprising: network side receives a service switching request information taking with an intention multicast service information sent by UE and a user identification information; the network side performs an operation for switching multicast service based on an original multicast service information corresponding to the intention multicast service information and the user identification information. An embodiment of the invention can make UE achieve a rapid multicast service switching, saves a switching time and network resource, keeps a continuity of multicast service, and is in favor of the popularization and application of multicast service.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, device and system for terminal equipment to switch multicast services. Background technique [0002] With the development of network communication technology, various types of network communication technologies have emerged. Among them, multicast service, as a network communication technology that can carry mobile TV services (such as mobile TV services), is more and more widely used in All aspects of life and work. The mobile TV service provided by the multicast service includes: different multicast services (i.e. mobile TV services) in the same service area; and in different service areas, the same multicast service sends different service content ( That is, mobile TV business content). [0003] Currently, the MBMS (Multimedia Broadcast Multicast Service) service proposed by the R6 version of 3GPP (Third Generation Partnership Project) carries ...

AI Technical Summary

Problems solved by technology

The disadvantages of adopting this technical solution include: in the current situation where the MBMS service is used to carry the multicast service, the process of UE joining and exiting an MBMS service is very cumbersome and needs to wait for a long switching time, which affects the continuity of the multicast service. It affects the normal use of users; at the same time, when the UE activates multiple multicast services at one time, it takes a long time to activate these multicast services and occupies more network resources, which is not conducive to the rational allocation of network resources

[0005] Therefore, at present, in the case of terminal equipment switching multicast services, there is no technical solution that can overcome the shortcomings of waiting for a long switching time and affecting the continuity of multicast services
