Embodiment 1

[0176]The UE with MBMS capability is currently camping in cell 2 and does not receive MBMS services. Assume that the system broadcast of cell 2 carries the indication information that cell 3 belongs to another MBSFN area (it can also carry the identity of the MBSFN area 2, or the MBSFN area The identities of service 3 and service 4 that can be provided, or carry indication information that other cells with the same coverage exist in the MBSFN area, or do not carry relevant information), if the UE has CA capability (that is, it can work on multiple component carriers at the same time), the UE You can choose to read the MCCH information of cell 2 and cell 3 at the same time. If the UE does not have the CA capability, the UE can read the MCCH information of cell 2 and cell 3 at different times, and then save them. In the currently obtained MCCH information of cell 2 and cell 3, the UE does not find the interested MBMS service. Then the UE monitors the Notification information of ...

Embodiment 2

[0178] The UE resides in cell 2 and is receiving service 1 provided by MBSFN area 1, and at the same time periodically receiving MCCH information of MBSFN area 1. Assume that the system broadcast of cell 2 carries the indication information that cell 3 belongs to another MBSFN area (it can also carry the identification of the MBSFN area 2, or the identification of the service 3 and service 4 that the MBSFN area can provide, or carry the information of other cells with the same coverage There is indication information of the MBSFN area, or does not carry relevant information), if the UE has the CA capability (that is, it can work on multiple component carriers at the same time), the UE can choose to read the MCCH information of cell 2 and cell 3 at the same time, if the UE does not With the CA capability, the UE can read and save the MCCH information of cell 2 and cell 3 at different times. The UE does not find the interested MBMS service in the currently obtained MCCH informat...

Embodiment 3

[0180] The UE has established a connection with cell 2, and there is data sending and receiving of unicast services. Assume that the system broadcast of cell 2 (or RRC (radio resource control) dedicated signaling) carries indication information that cell 3 belongs to another MBSFN area (it may also carry the identity of the MBSFN area 2, or the service 3 that the MBSFN area can provide and service 4, or carry indication information that other cells with the same coverage exist in the MBSFN area, or do not carry relevant information), if the UE has the CA capability (that is, can work on multiple component carriers at the same time), the UE can choose to read For the MCCH information of cell 2 and cell 3, if the UE does not have the CA capability, the UE can read the MCCH information of cell 2 and cell 3 at different times, and then save them. In the currently obtained MCCH information of cell 2 and cell 3, the UE does not find the interested MBMS service. Then the UE monitors...

Abstract

The invention relates to a wireless communication technology, in particular to methods, a system and a device for transmitting system information and receiving a multimedia broadcast multicast service (MBMS), which are used for solving the problem that a user terminal cannot receive MBMS data in a multicast broadcast single frequency network (MBSFN) region overlapped by a plurality of carriers in the prior art. The method for receiving the MBMS comprises the following steps that: the user terminal monitors control information of the MBSFN region of at least one of a plurality of frequency layers according to received system information on the network side; and the user terminal receives the corresponding MBMS data through a multicast traffic channel (MTCH) in the MBSFN region according to the monitored control information if a required MBMS exits in the MBSFN region. By the method of the embodiment of the invention, the system efficiency and a user experience can be improved.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for sending system information and receiving MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service). Background technique [0002] MBMS is used to provide multimedia broadcast services and multimedia multicast services to user terminals (UEs) in a wireless cell. [0003] In the LTE (Long Term Evolution, Long Term Evolution) system, MBMS can be provided on both a frequency layer dedicated to MBMS and a frequency layer shared with non-MBMS. An LTE cell supporting MBMS can be an MBMS dedicated cell or an MBMS / unicast hybrid cell. When performing MBMS transmission, single-cell transmission or multi-cell transmission can be performed. [0004] The MBMS dedicated frequency layer refers to a frequency layer dedicated to MBMS transmission. When a cell is configured as an MBMS dedicated frequency layer, the cell is c...
