The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

An embodiment of the present invention provides a transmission control method, where an eNB receives local area information Local The validity information is sent to the UE, and the local area information is used by the UE to determine an MBMS service or an MBMS session to be received. The local area information may include one or more areas capable of characterizing the area, thereby indicating an area to which the eNB belongs, for example: area shape Shape, country code cc, mobile country code mcc, area name name_area, zip code zipcode , cell target area identifier, or latitude and longitude index, and the like. The local area information may be a code compiled by the operator and provided directly or indirectly by the BM-SC to each network entity (such as an MCE or an eNB). For example, the area code compiled by the operator is the latitude and longitude index, which is the number generated by the operator according to the latitude and longitude. If the longitude is increased by one step (such as 0.3 degrees), the number is increased by 1, and the latitude is increased by one step ( For example, 0.5 degrees), the number is increased by N, and N is the number of each line compiled according to the longitude, so that an area (such as the MBSFN area) can be divided into several small areas, and each small area corresponds to one latitude and longitude index. . For another example, the area code compiled by the operator is the code that the operator divides the map into several pieces, and each piece corresponds to the code.

Correspondingly, after receiving the local area information, the UE may only receive the MBMS service or the MBMS session in the area indicated by the local area information, thereby preventing the UE from directly listening to the MBMS service channel or receiving the MBMS service that all UEs can receive. , reduce the power consumption of the UE.

Further, the local area information may be carried in some control messages sent by the eNB to the UE,

The upper layer application entity of the UE participates in the process of receiving the local area information, and only the underlying entity of some UEs receives the local area information, thereby further reducing the power consumption of the UE. For example, the eNB carries the local area information in the MBMS Control Channel (MCCH) message, and the UE can receive the MCCH message through the RC layer protocol, that is, the local area information can be implemented without the participation of the upper layer application entity of the UE. Analysis. For example, if the eNB carries the local area information in the MCH Scheduling Information (MSI) message, the MAC layer entity of the UE can receive the MSI message to implement local area information parsing.

Further, the upper layer application entity of the UE may receive the location information, or the location system of the UE may obtain the location information, where the location information indicates the location where the UE is currently located (position^the bottom layer of the UE may be after receiving the local area information, Combining the local area information and the foregoing location information, determining which MBMS services or MBMS sessions are received. For example, the bottom layer entity of the UE determines whether the local area information and the location information received by the upper application entity of the UE match, and if yes, the local area information or The MBMS service corresponding to the location information is the MBMS service that the UE needs to receive. If there is no match, the UE may not receive the MBMS service corresponding to the local area information or the location information. The matching here may include: the area range indicated by the local area information and The area ranges indicated by the location information are all overlapping or partially overlapping. For example, the local area information is the same as the location information, and the area coverage of the eNB indicated by the local area information is covered or covered by the location where the UE indicated by the location information is currently located. Optionally, in order to more accurately determine the MBMS service or the MBMS session that needs to be received, the bottom layer of the UE may select information indicating a smaller area and receive the MBMS service or the MBMS session corresponding to the information. Here, the MBMS session is a piece of data sending unit of a certain MBMS service, and the MBMS service data needs to be sent through each MBMS session establishment. The local area information may be carried by the MBMS session control data, that is, the UE may determine which specific MBMS sessions in the local news corresponding to the local area information according to the message carrying the local area information, or the specific MBMS service needs to be received. .
