Embodiment Construction

[0048] In order to solve the problem of receiving MBMS continuity when the UE moves between areas covered by MBSFN / IMB carriers and areas without MBSFN / IMB carrier coverage in a network where MBSFN / IMB is deployed, an embodiment of the present invention provides a method for receiving MBMS The method will be described in detail below in conjunction with specific embodiments.

[0049] For a UE equipped with dual receivers, if the UE receives MBMS through the MBSFN / IMB carrier, but the UE moves to the edge of the carrier coverage during the receiving process, and the signal quality of the MBSFN / IMB carrier cannot meet the UE's reception requirements, the UE It cannot continue to receive MBMS through the MBSFN / IMB carrier, nor can it use the FDD or TDD carrier to continue receiving, resulting in data loss; or when the UE moves from a cell without MBSFN / IMB carrier coverage to a cell with MBSFN / IMB carrier coverage , It is also impossible to switch from the established FDD or TDD ...

Abstract

The invention relates to a method for receiving multimedia broadcast and multicast service, comprising the following steps of: receiving MBSFN / IMB (Multicast Broadcast Single Frequency Network) / (Integrated Mobile Broadcast) carrier measuring information issued by a network side by a terminal and carrying MBSFN / IMB carrier signal quality standard; measuring the MBSFN / IMB carrier by the terminal and comparing the measuring result with the MBSFN / IMB carrier signal quality standard; receiving MBMS (Multimedia Broadcast Multicast Service) by using the MBSFN / IMB carrier if the measuring result reaches the MBSFN / IMB carrier signal quality standard; and avoiding using the MBSFN / IMB carrier to receive the MBMS if the measuring result fails to reach the MBSFN / IMB carrier signal quality standard. The invention also provides a corresponding terminal and a system including the terminal and a network side network element. The invention can solve the problem of the continuity for receiving the MBMS when the UE (User Equipment) moves in different carrier covering regions.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for receiving Multimedia Broadcast and Multicast Service (MBMS, Multimedia Broadcast Multicast Service). Background technique [0002] With the popularization of large-screen multifunctional mobile phones, the application of mobile data services is becoming more and more extensive. The Partnership Project (3GPP) proposes multimedia broadcast and multicast services, which provide a point-to-multipoint service in which one data source sends data to multiple users in a mobile network, realizes network resource sharing, and improves network resource utilization, especially Valuable air interface resources. MBMS defined by 3GPP can not only realize plain text low-rate message multicast and broadcast, but also realize multicast and broadcast of high-speed multimedia services, and provide a variety of rich video, audio and multimedia services. ...
