The embodiment of the invention provides a wireless network inter-node fission type clock synchronization system and method. The system comprises N nodes including a standard node. A preset time period is divided into n time slots. The N nodes are respectively corresponding to one time slot of the n time slots. The standard node communicates with a satellite to acquire a standard clock. Other nodes in the system communicate with the standard node to perform clock synchronization and then transmit clock synchronization information to the adjacent nodes in the corresponding time slots so that synchronization of all the nodes in the whole system with the standard clock can be completed, only one node in the system requires to communicate with the satellite, other nodes transmit the clock synchronization information in turn to complete clock synchronization and thus occupation of the communication resources can be saved and the cost of clock synchronization can be greatly reduced.
Description
Technical field [0001] The present invention relates to wireless communication technology, in particular to a fission type clock synchronization system and method between nodes in a wireless network. Background technique [0002] With the continuous development of communication technology, the requirements for the accuracy and reliability of communication are getting higher and higher. In a communication network, clock synchronization is required between various nodes. For example, multiple base stations (Base Station, referred to as BS) need to maintain clock synchronization. If the clock synchronization between the base stations is not done well, then when the user equipment (User Equipment, Referred to as UE) when moving from the coverage of one base station to the coverage of another base station, the problem of disconnection may occur. [0003] In the prior art, in order to improve the accuracy of clock synchronization, each node in the network performs clock synchronization ...
