Problems solved by technology

That is to say, there is a lack of a technical means for the subordinate network elements to distinguish between no service data transmission and data packet loss, so as to realize synchronous transmission of multiple MBMS services multiplexed into the same channel among multiple network elements

Embodiment Construction

[0039] The present invention is applicable to the MBMS (Multimedia Broadcast Multicast Service) content synchronization method and system of technologies such as TD-SCDMA, WCDMA, HSPA+ (High Speed ​​Packet AccessPlus) and 3GPP LTE (Long Term Evolution), and is used for MBMS service data packet loss Packet detection and avoidance of radio interface interference.

[0040] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0041] Such as figure 1 As shown, it is a logical architecture diagram of the master network element and the slave network element in the present invention, and the same master network element contains multiple slave network elements (from slave network element 1 to slave network element N, where N is a natural number).

[0042] The master network element is one of the following network elements: multimedia broadcast multicast service gateway (MGW), master node B plus...

Abstract

The invention discloses a synergistic method for element locations of multimedia broadcast multicasting services, which comprises the following steps that a master control element location synergistically collaborate with at least one slave element location so as to realize that multiple element locations are synchronously sent and multiplexed to a plurality of multimedia broadcast multicasting services of the same channel; and when the master control element location detects that the service data of a certain multimedia broadcast multicasting service is not needed to be sent within a certainperiod of time, the master control element location sends notification message to the slave element location so as to indicate that the service data of the certain multimedia broadcast multicasting service is not needed to be sent within the period of time. In a group of element locations sending MBMS services synchronously, when multiple MBMS services multiplex the channel, the synergistic methodcan ensure that the slave element location discriminates conditions of the data packet loss and no data sending of the MBMS services so as to correctly judge whether MBES service data on the multiplexing channel can be sent and prevent wireless interference caused by misjudgment among cells.

Description

technical field [0001] The invention relates to a communication technology, in particular to a coordination method between network elements of multimedia broadcast and multicast services. Background technique [0002] Now people's demand for mobile communication is no longer satisfied with telephone and message services. With the rapid development of the Internet, a large number of multimedia services have emerged. For some of these application services, multiple users can receive the same data at the same time, such as video on demand, TV broadcasting, video conferencing, online education, and interactive games. MBMS (Multimedia Broadcast Multicast Service) technology is proposed to realize the most effective use of mobile network resources. It refers to a point-to-multipoint service in which one data source sends data to multiple users to achieve network resource sharing, including mobile core network and access Network resource sharing, especially air interface resources...
