Embodiment Construction

[0036] In the embodiment of the present invention, the network side determines the MBMS control information type corresponding to the changed MBMS control information according to the corresponding relationship between the MBMS control information and the MBMS control information type, and sends the change instruction information corresponding to the determined MBMS control information type to the user terminal. Instructing the user terminal to acquire the changed MBMS control information according to the received change indication information. Since the user terminal can be notified when the MBMS control information changes, the user terminal can reduce receiving the same MBMS control information, thereby saving the power consumption and resources of the user terminal.

[0037] In the LTE (Long Term Evolution, long-term evolution) system, there are many types of MBMS, the following are listed:

[0038] 1. Streaming media, such as: TV programs, sports broadcasts.

[0039] Ses...

Abstract

The invention relates to wireless communication technology, in particular to a method, a system and a device for informing information change and acquiring information, which are used for solving the resource waste problem caused by that multimedia broadcast / multicast service (MBMS) control information which is transmitted by a network side on a multipoint control periodically channel (MCCH) may be the same, so that a user terminal repeatedly receives the same MBMS control information. The method of the embodiment of the invention comprises the following steps of: determining the types of theMBMS control information corresponding to the changed MBMS control information by using the network side according to the corresponding relationship between the MBMS control information and the type of the MBMS control information; and transmitting change indication information corresponding to the determined type of the MBMS control information to the user terminal, wherein the change indicationinformation is used for indicating the user terminal to acquire the changed MBMS control information. The method of the embodiment of the invention has the advantage of reducing the frequency of the user terminal receiving the repeated MBMS control information, thereby saving the resources.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for notifying information changes and acquiring information. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service) is used to provide multimedia broadcast services and multimedia multicast services for user terminals in wireless cells. [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 ...
