Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The embodiment of the invention relates to a communication module detection method. The specific flow is shown in figure 1.
and 103, storing the sub-frequency bands supported by the communication module.
The communication module detection method of the embodiment is used in a mobile terminal, such as a mobile phone. Because the communication service of the mobile terminal needs to be provided by the operator, and the communication frequency bands used by different operators are different, in order to implement the communication service of the mobile terminal, a communication module needs to be correspondingly equipped for the mobile terminal according to the use frequency band of the operator. The application programs in the mobile terminal are generally not differentiated and developed for the used frequency bands, but integrated into compatible application programs compatible with each frequency band, and when the mobile terminal is actually used, the mobile terminal needs to acquire the actual available frequency band of the communication module to correspondingly realize the functions. In the prior art, a GPIO pin needs to be provided for a communication module, and a mobile terminal can determine whether the communication module supports the use of certain frequency bands according to the state of the GPIO pin, so as to select the frequency bands to be used. Therefore, if the GPIO pins of the communication module are not enough and some frequency bands are not equipped with pins, the mobile terminal cannot know that the frequency bands are available.
The communication module detection method can judge which frequency bands of a 2G frequency band, a 3G frequency band, a 4G frequency band and a 5G frequency band are supported by the communication module by reading the calibration file of each frequency band, detect whether the locked frequency bands are supported by the communication module by sequentially calibrating each frequency band of the frequency band corresponding to the file, store the frequency bands supported by the communication module, and know which frequency bands of the frequency bands supported by the communication module, so that the mobile terminal can know the actual available frequency bands of the communication module without assembling identification hardware pins of each frequency band for the communication module.
The following describes implementation details of the communication module detection method according to the present embodiment in detail, and the following is only provided for easy understanding and is not necessary to implement the present embodiment.
In step 101, the mobile terminal reads a calibration file of each frequency band, wherein the frequency band includes any one of a 2G frequency band, a 3G frequency band, a 4G frequency band and a 5G frequency band;
specifically, after the mobile terminal is powered on, it immediately determines which frequency bands among 2G, 3G, 4G, and 5G are supported by the communication module. The Mobile terminal may read whether a Non-volatile memory (NV) memory has a calibration file corresponding to each frequency band, for example, if the communication module supports 2G communication, a Global System for Mobile communications (GSM) calibration file may exist in the NV memory of the Mobile terminal. If the mobile terminal can read the GSM calibration file, the communication module of the mobile terminal can be judged to support 2G communication, and if the mobile terminal cannot read the GSM calibration file, the communication module of the mobile terminal can be judged to not support 2G communication.
In step 102, the mobile terminal sequentially locks each sub-band of the frequency band corresponding to the calibration file, and detects whether the communication module supports the locked sub-band. Specifically, after adjusting a Radio Frequency (RF) parameter of the communication module by sequentially locking a Frequency band (band Frequency), that is, in a band locking manner, the mobile terminal detects whether the communication module is available, so as to determine whether the communication module supports the band Frequency.
In an example, the mobile terminal may also obtain only preset sub-bands of the frequency band corresponding to the calibration file, sequentially lock the preset sub-bands, and detect whether the communication module supports the locked preset sub-bands, where the preset sub-bands may be some sub-bands other than some sub-bands supported by most mobile terminals, or some sub-bands that are different between different mobile terminals supporting different operators.
In this embodiment, the mobile terminal sequentially locks the preset sub-bands by acquiring each preset sub-band of the frequency band corresponding to the calibration file, and detects whether the communication module supports locking the preset sub-bands, so that the number of sub-bands to be tested in detection of the communication module and the sub-bands can be reduced, and the matching efficiency of the communication module is improved.
Further, the preset sub-band may also be a preset sub-band received by the mobile terminal, where the mobile terminal may provide a sub-band preset interface and receive the preset sub-band from the sub-band preset interface. In this embodiment, the mobile terminal receives the preset sub-band input by the user from the sub-band preset interface by providing the sub-band preset interface to obtain the preset sub-band, so that the sub-band to be tested can be set according to a real-time requirement without presetting the sub-band to be tested, and thus, a personalized frequency band test scheme is realized.
In step 103, the mobile terminal stores the sub-bands supported by the communication module for reading. Specifically, the mobile terminal may store the RF parameters of the sub-band supported by the communication module in a buffer for subsequent reading and use of the sub-band.
In one example, the mobile terminal may store the sub-band supported by the communication module as non-volatile data, that is, in the NV memory, so that the sub-band data in the NV memory may be directly read after each power-on without performing a calculation process of the sub-band again.
In this embodiment, the sub-bands supported by the communication module are stored as the nonvolatile data, so that the sub-bands supported by the communication module can be stored for a long time and are not lost along with the power on/off of the mobile terminal, thereby reducing the number of times of the communication module detection method that needs to be executed when the mobile terminal operates, and saving the calculation resources.
In one example, the mobile terminal may store the sub-bands supported by the communication module into a preset location of the nonvolatile memory, where the preset location is a location preset in the nonvolatile memory for storing the matching result of the communication module. In this embodiment, the mobile terminal stores the sub-bands supported by the communication module into the preset position of the nonvolatile memory, so that the mobile terminal can quickly obtain the matching result of the communication module from the nonvolatile memory, and the calculation resources consumed in the searching process are saved.
In one example, before storing the sub-bands supported by the communication module, the mobile terminal further needs to confirm that the mobile terminal successfully accesses the network through the sub-bands supported by the communication module, that is, the network is searched by using the sub-bands supported by the communication module, if the network can be searched, the sub-band is an available frequency band, the sub-band is stored, and if the network cannot be searched, the sub-band is an unavailable frequency band, the mobile terminal continues to test the next sub-band.
In this embodiment, the mobile terminal determines that the mobile terminal successfully accesses the network through the sub-band supported by the communication module before storing the sub-band supported by the communication module, so as to ensure that the stored sub-band is the currently available frequency band of the mobile terminal.
In one example, a compatible application may be compatible with three mobile terminals: the communication module A can realize 4G communication and 2G communication, the communication module B can only realize 4G communication and cannot use the B40 frequency band in the 4G frequency band, and the communication module C can only realize 4G communication and can use the B40 frequency band. After the mobile terminal is started, whether a GSM calibration file can be read in an NV memory is judged, if the GSM calibration file can be read, the communication module in the mobile terminal is judged to be a communication module A, and corresponding RF parameters are stored for compatible application programs to use. If the GSM calibration file cannot be read, the communication module in the mobile terminal is not the communication module a, and it is necessary to continuously determine which of the communication module B and the communication module C the communication module is. The mobile terminal performs network search by locking the B40 frequency band, if the network can be searched, the communication module in the mobile terminal is communication module C, otherwise, the communication module B is communication module B. And the mobile terminal writes the matching result into a preset position (flag zone bit) of the NV memory for storage, so that the communication module matching result can be directly read from the flag zone bit of the NV memory after the mobile terminal is started next time.
In an example, as shown in fig. 2, after the mobile terminal is powered on, the mobile terminal reads from the NV memory whether a GSM calibration file of the 2G network, or a Code Division Multiple Access ("CDMA") calibration file or a Time Division-Synchronous Code Division Multiple Access ("TDSCDMA") calibration file of the 3G network, or a Frequency Division Duplex (FDD) calibration file and a Time Division duplex (TDD ") calibration file of the 4G network exist in NV parameters. And then judging which network the mobile terminal belongs to at present, if the current mobile terminal is in the 4G network, locking a preset frequency band (special band) under the network by the mobile terminal, testing whether the communication module is available by using the preset frequency band, and if the communication module is not available, switching to another frequency band to test whether the communication module is available. If all sub-bands under the network are not available, then a handover to another available network (say 3G network) is made. If the testing communication module is available, loading the corresponding RF parameters, searching the network and accessing the cell to stay. If the network searching is normal, the RF parameters of the sub-band are written into the NV memory.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
