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 service

Example Embodiment

[0023] The technical solutions of the embodiments of the present invention are as follows: figure 1 shown, including the following steps:

[0024] Step 1: The UE sends a service switching request message carrying the destination multicast service information and user identification information; the UE can send the service change request information to the network side according to the pre-stored multicast service information, or can also send the service change request message according to the multicast service information obtained from the air interface. The service information sends service change request information to the network side.

[0025] The service switching request message may carry: destination multicast service information and user identification information.

[0026] The destination multicast service information may include a destination multicast service identifier, and optionally an association identifier. The destination multicast service identifier is the...

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 ...
