For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," and "third," etc. are used for distinguishing between different objects and not for describing a particular sequential order.
Referring to fig. 1, fig. 1 is a schematic diagram of an application environment provided in an embodiment of the present application, as shown in fig. 1, the application environment at least includes an embedded controller (Embedded Controller, EC) of a PC and a mobile communication module (Modem), wherein EC is an embedded controller for managing peripheral devices of the PC, and is integrated on a PC motherboard, and is capable of controlling peripheral devices such as a keyboard, a touchpad, a USB interface, a hard disk, an optical drive, and the like. The connection between the mobile communication module and the PC is mainly the connection between the mobile communication module and the EC. The EC comprises three extensible markup language (Extensible Markup Language, XML) files, XML1 is used for configuring the matching relation between different system SKUs (identifications of different PC models) and Band information, XML2 is used for configuring the matching relation between public land mobile networks (Public Land Mobile Network, PLMNs) of different user identity identification (Subscriber Identity Module, SIM) cards and Band information, and XML3 is used for configuring the matching relation between PLMNs of different operators and Band information. In one possible implementation manner, after the PC is started, the EC obtains a system SKU of the PC from a basic input output system (Basic Input Output System, BIOS) of the PC, uses the system SKU to match in XML1, and if the system SKU is successfully matched, writes corresponding Band information into a mobile communication module of the PC, thereby completing obtaining Band information of different models and realizing Band customization requirements of different models. In one possible implementation manner, after the SIM card is inserted into the PC, the mobile communication module may obtain the PLMN of the SIM card, and compare the obtained PLMN of the SIM card with the PLMN of the SIM card inserted last time to determine whether the PLMN is updated, if there is an update, the PLMN of the SIM card inserted currently is sent to the EC, the EC uses the PLMN to perform matching in XML2, if there is corresponding Band information in the PLMN, the EC writes the Band information into the mobile communication module of the PC, so as to implement writing the Band information customized by the country into the mobile communication module of the PC. In a possible implementation manner, the mobile communication module compares the PLMN in the system information block type 1 (SIB 1) received by the PC with the PLMN in the SIB1 received last time to determine whether the PLMN is updated, if there is an update, the PLMN in the current SIB1 is sent to the EC, the EC uses the PLMN to match in XML3, and if there is corresponding Band information in the PLMN, the EC writes the Band information into the mobile communication module of the PC, so as to implement writing Band information customized by the operator into the mobile communication module of the PC.
Referring to fig. 2, fig. 2 is a flow chart of a method for obtaining frequency band information according to an embodiment of the present application, where the method can be applied to EC, and the EC includes a first matching relationship between a system SKU of terminal devices of various models and first frequency band configuration information of corresponding terminal devices; as shown in fig. 2, the method includes steps 201-202:
201: and reading the target system SKU of the current terminal equipment.
In the embodiment of the present application, the first Band configuration information refers to Band information customized for various models. For example, the first Band configuration information may include country customized Band information and/or operator customized Band information, and further may include customized Band information in other scenarios; for example, the first Band configuration information may include Band information specific to various models, and the specific Band information does not include country-customized Band information and operator-customized Band information. After the current terminal device is started, the EC can read the system SKU of the terminal device, namely the target system SKU, from the BIOS. If the EC fails to read the target system SKU, the process is ended, and Band information in a nonvolatile memory (NVM) of the mobile communication module is kept unchanged.
202: if the target first matching relation corresponding to the target system SKU exists in the EC, writing the first frequency band configuration information corresponding to the target first matching relation into the mobile communication module of the current terminal equipment.
In the embodiment of the application, the EC comprises a first XML file, a second XML file and a third XML file; the first XML file is recorded with a first matching relation, the second XML file is recorded with a second matching relation between PLMN of each SIM card and second frequency band configuration information, and the third XML file is recorded with a third matching relation between PLMN of each operator and third frequency band configuration information. The second frequency Band configuration information refers to Band information customized by a country, and the third frequency Band configuration information refers to Band information customized by an operator.
And the EC uses the read target system SKU to match in the first XML file, and if a corresponding target first matching relation (such as SKU001-Band 33) exists in the first XML file, the first frequency Band configuration information (such as Band 33) corresponding to the target first matching relation is written into the mobile communication module of the current terminal equipment. For example, the EC may issue a Set command to the mobile communication module, and write the obtained first band configuration information into the NVM of the mobile communication module through the Set command. If the first matching relationship of the target corresponding to the target system SKU does not exist in the first XML file, the process is terminated, and the Band information in the NVM of the mobile communication module is kept unchanged.
It can be seen that, in the embodiment of the present application, the matching relationship between the system SKU of the terminal device of various models and the corresponding frequency band configuration information is added in the EC, after the current terminal device is started, the EC reads the system SKU of the current terminal device first, and then queries and matches the system SKU to determine whether the corresponding matching relationship is stored in the EC, if so, the frequency band configuration information in the matching relationship is obtained, and is written in the mobile communication module of the current terminal device. Therefore, the management and matching of the frequency band configuration information are carried out on the EC side, the matching flow of the mobile communication module side is reduced, and the abnormal risk of the mobile communication module is reduced. In addition, the frequency band configuration information is not required to be written into the image file in the software version, and only the XML file at the EC side is required to be maintained, so that the size of the image file is reduced, and the version upgrading performance is improved.
Referring to fig. 3, fig. 3 is a flow chart of a method for obtaining frequency band information, which is provided in an embodiment of the present application, and the method can be applied to EC, wherein EC includes a first matching relationship between a system SKU of various types of terminal devices and first frequency band configuration information of corresponding terminal devices, a second matching relationship between PLMNs of respective SIM cards and second frequency band configuration information, and a third matching relationship between PLMNs of respective operators and third frequency band configuration information; as shown in fig. 3, the method comprises steps 301-306:
301: reading a target system SKU of the current terminal equipment;
302: if a target first matching relation corresponding to the target system SKU exists in the EC, writing first frequency band configuration information corresponding to the target first matching relation into a mobile communication module of the current terminal equipment;
the specific implementation of steps 301 and 302 is illustrated in fig. 2.
303: receiving a first PLMN sent by a mobile communication module; the first PLMN is the PLMN of the SIM card inserted by the current terminal equipment;
in the embodiment of the present application, when the first Band configuration information does not include Band information customized by the country and Band information customized by the operator, after the current terminal device inserts the SIM card, the mobile communication module may acquire the PLMN of the SIM card, determine whether the acquired PLMN is the same as the PLMN of the SIM card inserted last time, if different, determine that the PLMN has an update, and send the acquired PLMN of the SIM card to the EC as the first PLMN.
304: if the target second matching relation corresponding to the first PLMN exists in the EC, writing second frequency band configuration information corresponding to the target second matching relation into the mobile communication module;
in the embodiment of the application, the EC uses the first PLMN to match in the second XML file, and if the target second matching relation corresponding to the first PLMN is obtained, the corresponding second frequency band configuration information is written into the mobile communication module. For example, the EC may issue a Set command to the mobile communication module, and write the acquired second band configuration information into the NVM of the mobile communication module through the Set command.
305: receiving a second PLMN sent by the mobile communication module; the second PLMN is the PLMN in the SIB1 received by the current terminal equipment;
in the embodiment of the application, the mobile communication module can acquire the PLMN in the SIB1 received by the terminal equipment, judge whether the acquired PLMN is the same as the PLMN in the SIB1 received last time, if the acquired PLMN is different from the PLMN in the SIB1 received last time, determine that the PLMN has update, and send the PLMN in the current SIB1 to the EC as a second PLMN.
306: if the target third matching relation corresponding to the second PLMN exists in the EC, writing third frequency band configuration information corresponding to the target third matching relation into the mobile communication module.
In the embodiment of the application, the EC uses the second PLMN to match in the third XML file, and if a target third matching relation corresponding to the second PLMN is obtained, the corresponding third frequency band configuration information is written into the mobile communication module. For example, the EC may issue a Set command to the mobile communication module, and write the obtained third band configuration information into the NVM of the mobile communication module through the Set command.
It can be seen that, in the embodiment of the present application, a first matching relationship, a second matching relationship and a third matching relationship are added in the EC, after the current terminal device is started, the EC reads a system SKU of the current terminal device, and then queries and matches the system SKU to determine whether a corresponding matching relationship is stored in the EC, if so, frequency band configuration information in the matching relationship is obtained, and the frequency band configuration information is written in a mobile communication module of the current terminal device. After the current terminal device inserts the SIM card, the EC may use the obtained PLMN of the SIM card to perform query matching, so as to obtain Band information (i.e. second frequency Band configuration information) customized by the corresponding country. And, the EC may perform query matching by using the obtained PLMN in SIB1 to obtain Band information (i.e., third frequency Band configuration information) customized by the corresponding operator. Therefore, the management and matching of the frequency band configuration information are carried out on the EC side, the matching flow of the mobile communication module side is reduced, and the abnormal risk of the mobile communication module is reduced. In addition, the frequency band configuration information is not required to be written into the image file in the software version, and only the XML file at the EC side is required to be maintained, so that the size of the image file is reduced, and the version upgrading performance is improved.
Based on the description of the above embodiment of the method for acquiring the frequency band information, the embodiment of the present application further provides a device for acquiring the frequency band information, where the device is applied to EC, and the EC includes a first matching relationship between a system SKU of terminal devices of various models and first frequency band configuration information of corresponding terminal devices.

and the processing unit 402 is configured to write the first frequency band configuration information corresponding to the target first matching relationship into the mobile communication module of the current terminal device if the target first matching relationship corresponding to the target system SKU exists in the EC.
It can be seen that, in the frequency band information obtaining apparatus shown in fig. 4, by adding the matching relationship between the system SKU of the terminal device of various models and the corresponding frequency band configuration information in the EC, after the current terminal device is started, the EC reads the system SKU of the current terminal device first, and then uses the system SKU to perform query matching to determine whether the corresponding matching relationship is stored in the EC, if so, the frequency band configuration information in the matching relationship is obtained, and is written into the mobile communication module of the current terminal device. Therefore, the management and matching of the frequency band configuration information are carried out on the EC side, the matching flow of the mobile communication module side is reduced, and the abnormal risk of the mobile communication module is reduced.
