Method and device for processing multimedia broadcasting multicast service

Abstract

The embodiment of the invention discloses a method and a device for processing a multimedia broadcasting multicast service (MBMS). The method comprises the following steps that: when cells which belong to different time slot networks and are mutually adjacent cells transmit the MBMS service with the same configurations, indication information is broadcast in each cell to indicate frequency pointsfor the cell to transmit the MBMS service, and the adjacent cell of the cell transmits the MBMS service with the same configuration as the cell, thus when UE is ready to be switched to the adjacent cell, the UE switches the frequency to a corresponding frequency point and receives the MBMS service according to the original configuration. In the embodiment of the invention, the method and the device make the UE know the adjacent cell by broadcasting the indication information so as to transmit the MBMS service with the same configuration as the current cell, and the adjacent cell transmits thefrequency points of the MBMS service so that when the UE is ready to be switched to the adjacent cell, the MBMS service can be continuously received with the original configuration by switching the frequency points and the continuity of the receiving process of the MBMS service is ensured. The MBMS service is received according to the configuration corresponding to the configuration parameters ofthe adjacent cell.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to an MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service) processing method and device in the handover process. Background technique [0002] The realization of MBMS means that users receive broadcast digital audio and video content (such as TV programs, etc.) in the form of channels or channels on intelligent mobile terminals with operating systems and video functions. Widely concerned by the industry, it is regarded as a business with good application prospect in the third generation mobile communication system. [0003] The current broadcast system generally adopts the same frequency network technology to realize MBMS. The same frequency network technology is called UTN (United timeslolt network, time slot network) technology in the TD-MBMS system. Its requirements: all adjacent base stations in the broadcast...

Problems solved by technology

[0008] In view of this, the present invention provides an MBMS processing method and device to solve the problem that the UE needs to interrupt reception of MBMS when the old and new cells broadcast the same service when the UE moves between cells belonging to different UTNs.
