Embodiment Construction

[0034] Herein, an MBSFN overlapping area refers to an area covered by two or more MBSFN areas, and the same MBSFN overlapping area means that each cell in this area is covered by the same MBSFN area group, and the MBSFN area group consists of two or more More MBSFN areas constituted. Such as image 3 As shown, when the three MBSFN areas of MBSFN1, MBSFN2 and MBSFN3 have overlapping coverage, the cells in the M1 area are all under the overlapping coverage of the MBSFN area group composed of MBSFN1 and MBSFN2; the cells in the P1 area are all covered by the MBSFN1, MBSFN2 Under the overlapping coverage of the MBSFN area group composed of MBSFN3, the M1 area and the P1 area are different overlapping areas. The non-overlapping area referred to herein refers to an area covered by only one MBSFN area.

[0035] Herein, a border cell refers to a cell at the border of different MBSFN overlapping areas, or a cell at the border of an MBSFN overlapping area and an MBSFN non-overlapping ...

Abstract

The invention discloses a multimedia broadcast multicast service bearing method and a control device. The method includes: respectively configuring a multi-cell mode primary multiplex for each cell in a non-border position in the same multimedia broadcast multicast service single frequency network MBSFN overlapping area. broadcast control channel P-MCCH, and allocate the same multicast resource for the P-MCCH of each cell, and each cell constitutes the combined range of the P-MCCH or a part of the combined range, and each of the cells All multimedia broadcast and multicast services of a cell, that is, the main multicast control signaling of MBMS services are carried on the P-MCCH of the multi-cell mode of this cell; each cell at a non-border position in the MBSFN overlapping area has only one P-MCCH , the centralized placement of the MBMS service control signaling is realized, and it is convenient for the terminal to know all the related control information of the MBMS service in the cell at one time.

Description

technical field [0001] The present invention relates to an LTE (Long Term Evolution, Long Term Evolution) system, in particular to a multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, MBMS for short) bearing method and control device. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile phones, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferences, TV broadcasts, video on demand, advertisements, online education, interactive games, etc. On the one hand, it satisfies the ever-increasing business demands of mobile users, and at the same time brings 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, ...
