Background
With the development of communication technology, Long Term Evolution (LTE) networks are becoming more and more popular, and terminal devices, such as mobile phones, all perform various voice and data services through the LTE networks. In a long term evolution network, the Tracking Area is divided into a plurality of Tracking Areas (TAs), the Tracking Area is identified by a Tracking Area Code (TAC), a terminal registers in the long term evolution network through a Tracking Area Update (TAU), after the Tracking Area Update is completed, the long term evolution network replies a Tracking Area Code to the terminal, the terminal keeps synchronization with the network based on the Tracking Area Code in the network where the Tracking Area resides, if the terminal recovers after the current Tracking Area Code is dropped from the network, synchronization with the network can be kept without restarting the Tracking Area Update registration, and when the terminal moves to other Tracking areas, the terminal needs to acquire a new Tracking Area Code by restarting the Tracking Area Update registration.

In the current long-term evolution network, under the condition that a terminal receives a plurality of tracking area codes after a tracking area is updated, the condition of network desynchronization caused by different tracking area codes is easy to occur after network drop recovery, so that the terminal cannot receive paging messages sent by the network. The embodiment of the present disclosure provides a terminal network synchronization method S10, referring to fig. 1, including steps S11 to S14, which is described in detail below:
step S11, the tracking area update registration is performed with the network.
When the terminal enters a long-term evolution network or enters another tracking area in long-term evolution, the terminal updates the tracking area, registers the tracking area and updates the tracking area, thereby ensuring that the terminal can be synchronous with the network and receives paging in the tracking area. In one example, the network is a tracking area network in a long term evolution network.
In step S12, a plurality of tracking area codes are received.
After the terminal completes the updating of the tracking area, the terminal receives a plurality of tracking area codes sent by the network.
In one example, receiving a plurality of tracking area codes comprises: a Tracking Area identification table (Tracking Area List TAI) is received, the Tracking Area identification table comprising a plurality of Tracking Area codes. Wherein the tracking area identification table may be one or more.
Step S13, residing in the network based on a first tracking area code of the plurality of tracking area codes.
The terminal maintains synchronization with the network based on one of the tracking area codes while camped on the network, and may receive a page.
And step S14, reconnecting the network after disconnecting the network, and updating and registering the tracking area to the network.
After the terminal is disconnected with the network for some reasons, the terminal is reconnected with the network, and the situation that the terminal cannot receive the paging message sent by the network due to network desynchronization is easy to occur at the moment, so that the terminal forcibly updates and registers the tracking area with the network to acquire a new tracking area code, thereby ensuring the synchronization with the network.
In one example, referring to fig. 2, the step S14 is to reconnect the network after disconnecting from the network, and perform tracking area update registration with the network, and further includes: reconnecting the network after disconnecting from the network, residing based on a second tracking area code of the plurality of tracking area codes; and when the second tracking area code is different from the first tracking area code, updating and registering the tracking area to the network. In order to save network resources and communication cost, after the terminal is disconnected and reconnected with the network, whether the reconnected tracking area code is consistent with the tracking area code before disconnection is judged, if so, the tracking area code is kept in a resident state, and if not, the tracking area code is forced to be updated and registered with the network, so that desynchronization with the network is avoided, and user experience is improved.
