Abstract

The invention discloses a method and a system for transmitting and receiving data. The method for transmitting the data comprises the following steps: when each designated network element in multipledesignated network elements performs wireless link control protocol processing on data packets in received data bursts, assigning a scheduled wireless link control sequence number to a first wirelesslink control protocol data unit corresponding to a first data packet in the data bursts; sequentially assigning the wireless link control sequence numbers to the subsequent wireless link control protocol data units corresponding to the data packets in the data bursts according to a scheduled rule; and transmitting the protocol data units corresponding to the data packets in the data bursts to a user terminal. In the process of transmitting the protocol data units, the method is used to identify the same data burst identification on the protocol data units belonging to the same data burst, so that the user terminal can perform RLC processing on the protocol data units belonging to the same data burst to avoid the wireless interference among neighbouring cells.

Description

technical field [0001] The invention relates to the communication field, in particular to a data sending and receiving method and a data sending and receiving system. Background technique [0002] With the rapid development of the Internet network, a large number of multimedia services have emerged, and people's demand for mobile communications is no longer satisfied with telephone and message services. At present, application services have been introduced into multimedia services. The feature of application services is that multiple users can simultaneously Receive the same data, such as video on demand, TV broadcast, video conferencing, online education, interactive games, etc. [0003] In order to effectively utilize mobile network resources, a Multimedia Broadcast Multicast Service (MBMS) technology is proposed. MBMS is a point-to-multipoint service in which one data source sends data to multiple users. Through this service, it is possible to Realize network resource sh...
