Problems solved by technology

[0011] During the research and practice of the existing technology, it is found that the existing technology has the following problems: when the UE receiving the MBMS service is moving, the UE only considers the continuity of the unicast service when reselecting the cell or making a handover decision at the network side , if multiple component carriers are deployed in the network, the UE may cell reselect or be handed over to a target cell different from the CC where the MBMS service is located, resulting in interruption of the MBMS service and degrading the user's MBMS service experience; within the MBMS service area, The UE receiving MBMS service through PTM moves to a non-MBSFN area or to a reserved cell in an MBSFN area. At this time, the MBMS service is interrupted, which reduces the user's MBMS service experience; in the MBMS service area, the UE receiving MBMS service through PTP When the UE moves to a non-reserved cell in the MBSFN area, the MBMS service is sent through PTP and PTM at the same time, resulting in a waste of resources

Embodiment 1

[0071]The scenario of Embodiment 1 is: the UE moves within the MBMS service area, multiple component carriers are deployed in the network, and the UE has CA capability, that is, the UE in connected mode can receive more than one component carrier at the same time, and the MBMS service is deployed on one of the component carriers Above, the UE prepares for cell reselection or the network side prepares for UE handover.

[0072] The method for implementing MBMS service continuity in Embodiment 1 includes:

[0073] Suppose the MBMS service is deployed on CC1, the UE receives the MBMS service on the source cell CC1, and the carrier frequencies of candidate target cells include CC1, CC2, and CC3; the network side knows the MBMS reception status of the UE, that is, the network side knows that the UE is receiving MBMS on CC1 service, the UE can actively report its own MBMS reception status or report its own MBMS reception status according to the request of the network side;

[0074] ...

Embodiment 2

[0079] The scenario of the second embodiment is: in the MBMS service area, the UE receiving the MBMS service through PTM moves from one MBSFN area to another MBSFN area, such as figure 2 Scenario A shown; or the UE receiving the MBMS service through PTM moves within the same MBSFN area, such as figure 2 Scenario B is shown.

[0080] Such as image 3 As shown, the method for realizing MBMS service continuity in Embodiment 2 of the present invention includes:

[0081] Step 301, UE moves from a source cell in MBFSN area 1 to a target cell;

[0082] The UE can judge whether the target cell is a cell in a certain MBSFN area through the system message. The specific method is: the UE reads the SIB1 of the target cell. If there is SIB13 related scheduling information in the SIB1, it means that the target cell is in a certain MBSFN area. district.

[0083] Step 302, UE judges whether the target cell is a reserved cell, if yes, executes step 306; otherwise, executes step 303;

[...

Embodiment 3

[0107] The scenario of the third embodiment is: in the MBMS service area, the UE receiving the MBMS service through PTM moves from the MBSFN area to the non-MBSFN area, such as figure 2 Scenario C shown.

[0108] Such as Figure 4 As shown, the method for realizing MBMS service continuity in Embodiment 3 of the present invention includes:

[0109] Step 401, the UE moves to a target cell, and the target cell belongs to a non-MBSFN area;

[0110] The non-MBSFN area means that the cells in the area do not send the system message SIB13; if the UE does not find the SIB13 of the target cell, it indicates that the target cell is a cell in the non-MBSFN area.

[0111] Step 402, the UE judges whether the target cell and the source cell belong to the same MBMS service area, if yes, execute step 403, otherwise, execute step 405;

[0112] Before the MBMS service starts, the BM-SC sends an announcement in the MBMS service area, which is used to introduce the content of the MBMS service...

Abstract

The invention discloses a method, user equipment, and a system for realizing continuity of multimedia broadcast and multicast service (MBMS). The method comprises that: when UE which is receiving or being interested in receiving MBMS moves, and when the UE is in an idle mode, the UE selects target cells having the same frequency with the MBMS and carries out cell reselection; or when the UE is in a connection mode, network side selects the target cells having the same frequency with the MBMS according to a receiving status reported by the UE and switches. MBMS experience of users can be improved by adopting the method, the user equipment, and the system of the invention.

Description

technical field [0001] The present invention relates to multimedia broadcast multicast service (MBMS, Multimedia Broadcast and Multicast Service), in particular to a method, user equipment and system for realizing continuity of multimedia broadcast multicast service. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional user equipment, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferencing, TV broadcasting, video on demand, advertising, online education, interactive games, etc. These services not only meet the needs of mobile users for multiple services, but also bring new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration,...
