Method, apparatus and system for data synchronization between base stations

Abstract

The invention relates to a data synchronization method between base stations, a data synchronization device therebetween, and a data synchronization system therebetween, wherein the data synchronization method between the base station comprises that: a plurality of base stations receive transmitting time tables and transmitting channel labels of data; the base stations checks the correctness of the data, and stores the data and the transmitting time tables and the transmitting channel labels of the data, according to the checking result; the base stations transmit the data to the user apparatus according to the transmitting time tables and the transmitting channel labels. The data synchronization device between the base stations comprises a first module, a second module and a third module connected in turn. The data synchronization system between the base stations comprises a content server and a device for realizing the data synchronization between the base stations. The invention has the function of error correction and retransmission, thereby effectively solving the problem of data asynchronous of relative base stations, advancing the receiving performance of the users.

Description

technical field [0001] The present invention relates to a method for synchronizing data between base stations, in particular to a method for ensuring data integrity and avoiding data out-of-sync between base stations; The invention relates to a system for data synchronization between base stations, especially a system capable of ensuring data integrity and avoiding data synchronization between base stations; it belongs to the field of wireless communication. Background technique [0002] Modern communication technology is playing an increasingly important role in human work and life. People have higher and higher requirements for the quality of data transmission. Data synchronization is a very important indicator to measure the quality of data transmission. In the multimedia broadcast multicast service system, since the downlink broadcast is used to transmit signals, the signals sent by multiple base stations can reach the receiving end at the same time. When multiple base ...

Problems solved by technology

The second type of situation is that although the base stations are synchronized, when the service source distributes data to each base station, some base stations have packet loss or error packets, so that after a certain time, the data sent by different base stations may be different. , resulting in severe interference; or at a certain moment, different base stations transmit different signals and interfere with each other

However, this method only passively detects the right or wrong of the transmission data block to decide whether to send it, and cannot correct the erroneous data block, resulting in the degradation of the signal reception quality in the relevant area
