Embodiment Construction

[0038] After research, the inventor found that: generally speaking, NITZ information includes network identification and time information. In practical applications, whether the message sent by the mobile communication network to the mobile terminal contains NITZ time information is determined by the operator of the mobile communication network, that is, some messages sent by the mobile communication network do not contain NITZ time information.

[0039] For existing dual-card dual-standby and multi-card multi-standby mobile terminals, the default card is usually used to obtain NITZ information from the mobile communication network. Once the mobile communication network corresponding to the default card does not provide time information, it will The system time of the mobile terminal cannot be updated.

[0040] In view of this, the inventor proposes an innovative solution for updating a mobile terminal to solve this technical problem.

[0041] In order to make the above objec...

Abstract

The invention discloses a method and a device for updating the time of a mobile terminal. The method includes: selecting a currently available subscriber identity card from the subscriber identity cards registered in the communication network in the mobile terminal; attaching the currently available subscriber identity card to the communication network in which it is registered; through the currently available subscriber identity card The user identification card can be used to obtain time information from the communication network; if the currently available user identification card fails to obtain the time information, the next available user identification card is selected in turn as the currently available user identification card until the mobile terminal obtains the time information from the communication network. Time information of the network; setting the time information as the system time of the mobile terminal. The invention can improve the success rate of updating the time of the mobile terminal, and can timely and conveniently update the time of the mobile terminal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for updating the time of a mobile terminal. Background technique [0002] At present, there are many types of mobile communication networks in the market, such as General Packet Radio System (GPRS, General Packet Radio System), Code Division Multiple Access (CDMA, Code Division Multiple Access) communication network, Time Division-Synchronous Code Division Multiple Access (TCDMA) TD-SCDMA, Time Division-Synchronous CDMA) communication network, etc. [0003] Since different mobile communication networks need to use different subscriber identification cards, there are currently many multi-card multi-standby mobile terminal products on the market to meet the requirements of different mobile communication networks. [0004] When people use these mobile terminal products, they often use it to check the time information, such as using a mobile phone to check the...
