no. 1 example

[0029] refer to figure 1 , which shows a flow chart of a time synchronization method according to an embodiment of the present invention, which is applied to a mobile terminal, and the method may specifically include the following steps:

[0030] Step 101, detecting whether the network where the mobile terminal is located changes.

[0031] When the location and environment of the user's mobile terminal change due to going abroad, etc., the network where the mobile terminal is located will change.

[0032] Therefore, it can be preliminarily judged whether the time zone of the user's location has changed by detecting whether the network where the mobile terminal (such as a mobile phone) resides has changed.

[0033] Step 102, if it is detected that the network where the mobile terminal is located changes, then judge whether the mobile terminal is connected to the emergency dial-up network.

[0034] Among them, if it is determined that the network where the mobile phone is loca...

[0043] refer to figure 2 , showing a flowchart of a time synchronization method according to another embodiment of the present invention, which is applied to a mobile terminal, and the method may specifically include the following steps:

[0044] Step 201, detecting whether the network where the mobile terminal is located changes.

[0045] Wherein, when the location and environment of the user's mobile terminal change due to going abroad, etc., the network where the mobile terminal is located will change.

[0046] Among them, the modem (commonly known as "cat") of the mobile terminal can be used to detect the network where the mobile terminal (such as a mobile phone) is located in real time. Also referred to as web server, the communication framework promptly encapsulates IO operations and provides a more advanced API interface. The communication framework of the embodiment of the present invention can be: MINA, Cindy, QuickServer, etc.) to notify the upper layer application...

[0064] refer to image 3 , shows a block diagram of a mobile terminal according to an embodiment of the present invention. The mobile terminal in the embodiment of the present invention can realize the details of the time synchronization method in the first embodiment to the second embodiment, and achieve the same effect. image 3 The illustrated mobile terminal 300 includes:

[0065] A modem 31, configured to detect whether the network where the mobile terminal is located changes;

[0066] A judging module 32, configured to judge whether the mobile terminal is connected to an emergency dial-up network if the modem 31 detects that the network where the mobile terminal is located has changed;

[0067] An acquisition module 33, configured to acquire cell information in the region where the mobile terminal is located if the judging module 32 determines that the mobile terminal is connected to an emergency dial-up network;

Abstract

Embodiments of the invention provide a clock synchronization method and a mobile terminal. The method comprises: detecting whether a network, where the mobile terminal is located, is changed; if the network, where the mobile terminal is located, is changed, judging whether the mobile terminal accesses an emergency dial-up network; if the mobile terminal accesses the emergency dial-up network, acquiring cell information of a region, where the mobile terminal is located; according to the cell information, determining a target clock zone, where the mobile terminal is located; and switching the clock zone, where the mobile terminal is located, into the target clock zone. According to the clock synchronization method and the mobile terminal, when the network, where the mobile terminal is located, is determined to be the emergency dial-up network, the time zone, where the mobile terminal is located, can be determined according to base station information of the region, where the mobile terminal is located, and automatic clock synchronization is implemented by switching the time zone. Therefore, even though no subscriber identification module (SIM) card is plugged in the mobile terminal or the mobile terminal does not access a mobile network or a wireless network, the automatic clock synchronization can also be implemented, so that automatic clock synchronization and correction of the mobile terminal can be implemented.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a time synchronization method and a mobile terminal. Background technique [0002] At present, the automatic time synchronization schemes of mobile terminals (such as mobile phones) mainly include the following two types: one is that the operator actively reports the correct time, and the other is automatic time synchronization through a data network (mobile network or wireless network such as wifi) . [0003] Among them, for the scheme that the operator actively reports the time, if the mobile terminal is not inserted with a SIM card (Subscriber Identification Module, customer identification module) or the SIM card is not inserted correctly, the operator cannot accurately push the local time. If the user goes abroad across the border, the time of the mobile terminal cannot be synchronized to the local time where the user is located. [0004] As for the automatic time sy...
