Problems solved by technology
[0004] In the actual network environment, when the cell status changes, the GSTK module cannot receive the network status change when processing the network status command at the corresponding MM_IDLE status change, that is, it cannot obtain the changed network status information. , so that the SIM module cannot be correctly driven to write the corresponding network status into the SIM card
[0005] From the perspective of the implementation process of the prior art, the current method for the mobile terminal to obtain network state information after the state of the cell changes cannot guarantee that the GSTK module obtains the correct network state information, nor can it update the network state after the cell state is correctly known. to the corresponding SIM card

Embodiment Construction
[0027] figure 2 It is a flow chart for obtaining network status information of the present invention, such as figure 2 As shown, including the following steps:
[0028] Step 200: the GSTK module registers the network status notification with the CM module;
[0029] Here, since every time the network status changes, the status reported by the CM module is always correct. Therefore, in this step, the GSTK module can instruct the CM module to change when the network status changes by registering a callback function with the CM module The subsequent network status is notified to the GSTK module. The specific implementation method of the registration callback function belongs to the usual technical means of those skilled in the art, and will not be repeated here.
[0030] Before this step, it also includes: inserting the SIM card in the mobile terminal, placing the mobile terminal within the network coverage area of a certain cell, after the mobile terminal is powered on, the CM modu...

The invention provides a method for obtaining network state information, comprising the following steps: a high-pass SIM card support capability set (GSTK) module registers network state notification to a connectivity management (CM) module; when the network state recorded by the CM module changes, the GSTK module is notified, and the GSTK module obtains the changed network state information. The invention also provides a device for obtaining network state information. If the device is adopted, the GSTK module can accurately sense the variation of the current network module state so as to ensure that a mobile terminal can obtain accurate network state information. Further, the method which writes the network state of the changed network module into the SIM card can ensure that an operator can know the variation state of the current network by the state of the SIM card so as to promote the development of mutually separated mobile terminal software and operator custom in the future.
Description
Technical field [0001] The present invention relates to smart mobile terminal technology, in particular to a method and device for a mobile terminal to obtain network state information after a cell state changes. Background technique [0002] Because of the powerful functions, strong operability, and easy installation of third-party software, smart mobile terminals have attracted more and more attention. The market prospects of smart phones are becoming more and more extensive, and the Global Certification Forum (GCF) test is an important test before wideband code division multiple access (WCDMA) mobile terminals enter commercial use. When the network state of the cell where the mobile terminal is located changes, whether the mobile terminal can correctly perceive the network state of the cell where it is located and write the corresponding network state information into the Subscriber Identity Module (SIM) card. Extending to the future can be understood as whether network opera...
