Abrégé
(EN)
The invention discloses a TA (Timing Advance) maintenance method, apparatus and system. The TA maintenance method comprises the steps of enabling a UE (User Equipment) to receive TA indication information sent by a network side; and enabling the UE to determine a TA value adopted in an inactive state or an idle state according to the TA indication information, wherein the inactive state refers toa state in which an interface between the UE and a first network device at the network side is disconnected, and an interface between the first network device and a second network device at the network side keeps a connection. According to the method, an uplink TA of the UE in the inactive state or the idle state can be maintained, and thus a lot of signalings and overheads are saved.

本发明公开了一种定时提前维护方法、装置及系统;上述定时提前维护方法包括:终端接收网络侧发送的TA指示信息;终端根据TA指示信息,确定在非激活态或者空闲态时采用的TA值;其中,非激活态指终端与网络侧的第一网络设备之间的接口断开且第一网络设备与网络侧的第二网络设备之间的接口保持连接的状态。上述方法能够维护处于非激活态或者空闲态的终端的上行定时提前,从而节约大量的信令和开销。
