Method and system for synchronizing network nodes in time division duplex system

摘要

The disclosure discloses a method for synchronizing network nodes in a time division duplex system. The method includes that: a network node acquires the cell identity information of other network nodes, and inquires the synchronization status information of the other network nodes from a synchronization information node according to the cell identity information; the network node implements synchronization policy according to its own synchronization status and the inquired synchronization status of the other network nodes. A system for synchronizing the network nodes in the time division duplex system is also disclosed, which includes an acquiring unit (60), an inquiring unit (61) and a implementing unit (62).

1. A method for synchronizing network nodes in a time division duplex system, comprising:
acquiring, by a network node, cell identity information of other network nodes via a radio interface, and inquiring synchronization status information of the other network nodes from a synchronization information node according to the cell identity information; and implementing, by the network node, a synchronization policy according to a synchronization status of the network node and an inquired synchronization status of the other network nodes, wherein the synchronization status at least comprises: being synchronous or not, and/or a synchronization level; and the synchronization policy comprises: when the network node is asynchronous, the network node is synchronized with a network node having a highest synchronization level amongst the other network nodes, or when the network node is synchronous, the network node is synchronized with a network node which has a highest synchronization level and has a synchronization level at least two levels higher than a synchronization level of the network node amongst the other network nodes.
