The embodiment of the application relates to the technical field of terminals, in particular to a data processing method, terminal equipment, a server side and a storage medium.

Background

Currently, most terminal devices are configured with software system update functionality. The manner in which The terminal device implements The software system update via wireless communication may be referred to as Over The Air (OTA) upgrade, or as online upgrade. Through the OTA technology, the terminal equipment can get rid of the restriction of the manual upgrading mode in time, place and other aspects, and update the software system anytime and anywhere. In this way, the terminal device can provide a better user experience to the user through the latest software system.

However, in some cases, after the OTA upgrade, the terminal device may have some abnormal loading of the modem configuration file, which may seriously affect the user experience.

Disclosure of Invention

The embodiment of the application provides a data processing method, terminal equipment, a server side and a storage medium, which are used for reducing the abnormal loading condition of a modem configuration file of the terminal equipment after OTA upgrading.

In order to achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

in a first aspect, a data processing method is provided, the method comprising: and responding to an over-the-air OTA upgrade completion event, and acquiring a plurality of general configuration files and card following configuration files corresponding to the terminal equipment in the card following configuration files from the configuration files of the first partition. The card following configuration file corresponding to the terminal equipment comprises network configuration information corresponding to a network operator of the location of the terminal equipment. And loading a plurality of general configuration files and card following configuration files corresponding to the terminal equipment in the second partition, and accessing the wireless communication network according to the plurality of general configuration files and the card following configuration files corresponding to the terminal equipment.

In the method, a memory space of the terminal device includes a first partition for storing a modem configuration file and a second partition for loading the modem configuration file. The modem profile includes a plurality of generic profiles provided for different devices and a plurality of card-along profiles. At least one general configuration file in a plurality of general configuration files in the modem configuration file is obtained based on at least one general configuration file which is not updated, and the card following configuration file corresponding to the terminal equipment comprises part of configuration information in the at least one general configuration file which is not updated. The card following configuration file corresponding to the terminal equipment is obtained by splitting part of configuration information in the general configuration file which is not updated. Compared with the general configuration file which is not updated, the general configuration file loaded by the terminal equipment has greatly reduced data volume. The card following configuration files corresponding to the terminal equipment only occupy a small part of the card following configuration files corresponding to the plurality of equipment, so that the data volume of the card following configuration files loaded by the terminal equipment is low. Therefore, the total data amount loaded by the terminal equipment in the second partition can be reduced, so that the second partition of the terminal equipment has enough memory space to load the modem configuration file, and the condition that some configuration information is not loaded due to insufficient space of the second partition is reduced. The terminal equipment can be connected with the wireless communication network through the loaded modem configuration file, and provides functions of calling, surfing the internet and the like for the user.

In a possible implementation manner of the first aspect, the first partition stores a first file, the second partition stores a first file, and the first file of the second partition is different from the first file of the first partition in content. The method further comprises the following steps: in the process of loading a plurality of general configuration files and card following configuration files corresponding to the terminal equipment in the second partition, if the first files of the first partition are different from the first files of the second partition, copying the first files in the second partition to obtain first temporary files, and modifying the first temporary files based on the first files in the first partition to obtain modified first temporary files. And replacing the first file in the second partition with the modified first temporary file.

In this implementation, the first file is one of a plurality of general configuration files and card-following configuration files corresponding to the terminal device. If the first file is a generic configuration file, the amount of data of the first file loaded by the terminal device in the second partition is substantially reduced compared to the non-updated generic configuration file. If the first file is an on-card profile, the on-card profile does not change much in data volume compared to the as-card profile that is not updated. In this way, the terminal device loads the first file in the second partition, and the probability of causing insufficient space of the second partition is smaller.

In another possible implementation manner of the first aspect, the card following configuration file corresponding to the terminal device is determined from the plurality of card following configuration files in the first partition according to an international mobile subscriber identity of the terminal device.

In the implementation mode, the terminal equipment can quickly determine the card following configuration file which needs to be loaded by the terminal equipment through the IMSI of the SIM card.

In another possible implementation manner of the first aspect, the network configuration information corresponding to the location where the terminal device belongs includes carrier aggregation information.

In this implementation, the carrier aggregation information loaded by the terminal device is in the card-following configuration file corresponding to the terminal device, rather than the general configuration file. In this way, the terminal equipment only needs to load carrier aggregation information of the terminal equipment, so that the data volume loaded by the terminal equipment in the second partition can be greatly reduced.

In another possible implementation manner of the first aspect, the method further includes: the wireless communication network is communicated with using a carrier combination indicated by the carrier aggregation information.

In this implementation manner, the terminal device may normally load the NV parameter, and access to the wireless communication network preferentially through the circuit switched domain or the packet switched domain indicated by the NV parameter, so as to provide services such as calling, surfing the internet, and the like for the user.

In another possible implementation manner of the first aspect, a total data amount of the plurality of general configuration files and the card-following configuration files corresponding to the terminal device is smaller than a preset data amount.

In this implementation, the total data amount loaded by the terminal device is smaller than the preset data amount, so that the situation that the remaining space of the second partition is insufficient can be reduced.

In another possible implementation manner of the first aspect, the method further includes: and receiving an OTA upgrading data packet sent by the server, acquiring a modem configuration file from the OTA upgrading data packet, and storing the modem configuration file in the first partition.

In this implementation, the terminal device may obtain the modem configuration file in the OTA upgrade data packet, update the software system of the terminal device, and update the modem configuration file.

In another possible implementation manner of the first aspect, the method further includes: and if the residual space of the second partition is smaller than the preset capacity, deleting the temporary file in the second partition. The end identifier of the file name of the temporary file is a preset identifier.

In this implementation manner, if the remaining space of the second partition is insufficient, the terminal device may further release the memory space of the second partition by deleting the temporary file in the second partition, so that the terminal device continues to load the modem configuration file in the second partition, thereby implementing normal access of the wireless communication network.

In a second aspect, the present application provides a data processing method, applied to a server, where the method includes: and responding to the configuration operation of the user, configuring a modem configuration file, wherein the modem configuration file comprises a plurality of general configuration files and a plurality of card following configuration files which are provided for different devices, and each card following configuration file corresponding to each device comprises network configuration information corresponding to a network operator of the place where the device is located.

Detailed Description

Currently, most terminal devices perform software system upgrades by OTA technology to add and modify some software functions. As shown in fig. 1, the server may send a data packet for upgrading a software system (may be referred to as an OTA upgrade data packet) to the terminal device through an OTA technology. The terminal device may update the software system according to the received data packet in response to an update operation by the user. Alternatively, the terminal device may automatically update the software system according to the received data packet during an idle period (e.g., 1-3 a.m.) when the user is not using the terminal device.

A modem (modem) is included in the terminal device. The modem is used for modulating a low-frequency baseband signal to be transmitted into a medium-high frequency signal and demodulating a received electromagnetic wave signal into a low-frequency baseband signal. The modem is a key device for wireless communication by the terminal device. The terminal device may involve a change in the modem configuration file (which may be referred to as a modem configuration file) during the OTA upgrade. The modem configuration file is typically stored in a terminal device specific memory area, which may be referred to as a modem configuration (Modem Configuration Framework, MCFG) partition. The MCFG partition is a memory space specially set by the terminal device for modem configuration files, and is used for storing all modem configuration files. The modem configuration file may be a binary file, which may be referred to as a MBN (Modem Configuration Binary) file. The MBN file is used to provide configuration information required for the terminal device to access the wireless communication network. For example, the MBN file may provide information on networks, antenna switch status, etc. that the terminal device is allowed to register.

If updating of MBN files in the MCFG partition is involved in OTA upgrading, the terminal equipment loads the MBN files in the MCFG partition after starting up so as to access the wireless communication network. The memory area used to load the MBN file may be referred to as an encrypted file system (Encrypting File System, EFS) partition. And the terminal equipment reads the MBN file in the MCFG partition to the EFS partition, so as to realize loading of the MBN file. EFS partition is an independent memory space in the terminal device, like a cache. The terminal device may run MBN files in the EFS partition directly. For example, the terminal device may access the wireless communication network according to the registration allowed wireless communication network indicated by the MBN file in the EFS partition.

Taking file 1 of the plurality of MBN files as an example, a procedure in which the terminal device reads the MBN file in the MCFG partition to the EFS partition will be described. The updated file 1 is stored in the MCFG partition. The EFS partition stores therein the file 1 that is not updated. The terminal device copies the file 1 that is not updated in the EFS partition to obtain a temporary file 1. The terminal device further modifies the temporary file 1 in the EFS partition according to the updated file 1 in the MCFG partition. After the modification is completed, the terminal device replaces the temporary file with file 1 (e.g., renames the temporary file to file 1). In this way, the terminal device can read the latest file 1 in the MCFG partition into the EFS partition, and load the latest file 1.

In the process of reading the file 1, the terminal device may also have read-write operations of other MBN files in the EFS partition. However, the memory space corresponding to the EFS partition is limited. If the residual space of the EFS partition is insufficient, the terminal device can stop the loading process, so that redundant temporary files appear in the EFS partition and occupy the memory space of the EFS partition.

Illustratively, taking the above file 1 as an example, as shown in (1) of fig. 2, if the terminal device normally loads the MBN file in the EFS partition, the temporary file 1 of the file 1 is not present in the EFS partition. If the terminal device does not normally load the MBN file in the EFS partition, as shown in fig. 2 (2), there is a temporary file 1 in addition to the file 1 in the EFS partition of the terminal device. Temporary file 1 is identical in content to file 1, and the file size of temporary file 1 is the same as the file size of file 1. It can be seen that temporary file 1 is completely redundant, and temporary file 1 occupies memory space in the EFS partition. If the remaining space of the EFS partition is too small, it is difficult for the terminal device to continue to read MBN files from the MCFG partition, resulting in some MBN files not being loaded normally, thereby affecting the access of the terminal device to the wireless network.

In the following, an example is taken in which the terminal device is a mobile phone, and a Non-Volatile Memory (NV) parameter in an MBN file of the mobile phone is not normally loaded. After the OTA upgrade, the handset updates the software system by restarting. After the mobile phone is restarted, the mobile phone reads the updated MBN file in the MCFG partition to access the wireless communication network.

In the process that the mobile phone loads the MBN file in the MCFG partition to the EFS partition, the mobile phone stops executing the loading of the MBN file due to insufficient residual space of the EFS partition. For example, where the remaining space of the EFS partition is only 222 kilobytes, the amount of data to be loaded by the handset is 280 kilobytes. If the EFS partition of the mobile phone cannot load 280 kilobytes of data, the current loading flow is stopped. At this point, one of the NV parameters (e.g., NV 66048) in the MBN file is not loaded normally. The NV parameter is used to indicate that the wireless communication network is to be accessed preferentially over a circuit switched domain (Circuit Switching Domain) (CS domain for short) or over a packet switched domain (Packet Switching Domain) (PS domain for short).

Because the mobile phone does not complete the loading of the NV parameters, the mobile phone can preferentially apply for the base station to access the wireless communication network through the CS domain by default. However, when the communication network signal of the PS domain is stronger than the communication network signal of the CS domain, the base station preferentially registers the wireless communication network of the PS domain for the mobile phone. In this case, the base station may refuse the terminal device to connect to the wireless communication network of the CS domain. The handset may not be able to access the wireless communication network due to the non-normal loading of NV parameters, which may seriously affect the user experience.

In view of this, embodiments of the present application provide a method. In this method, the server may configure a modem configuration file (i.e., the above MBN file) in response to a configuration operation of the user, and send the modem configuration file to the terminal device. The modem profile includes a plurality of generic profiles provided for different devices and a plurality of card-along profiles. The modem configuration file received by the terminal device does not include configuration information specific to some devices (such as network configuration information corresponding to a network operator of the device) in at least one common configuration file shared by different devices, and the configuration information specific to the devices is moved to the card following configuration files corresponding to the devices. In this way, the terminal device responds to the OTA upgrade completion event, and obtains a plurality of general configuration files and card following configuration files corresponding to the terminal device in the modem configuration files of the first partition (i.e. the MCFG partition). Further, the terminal device loads the obtained plurality of general configuration files and the card following configuration files corresponding to the terminal device in the second partition (namely the EFS partition), so that the wireless communication network can be accessed according to the loaded plurality of general configuration files and the card following configuration files corresponding to the terminal device.

By the method, the data volume of MBN files loaded in the EFS partition by the terminal equipment can be reduced, so that the EFS partition of the terminal equipment has enough memory space to load the MBN files, and the condition that some configuration information is not loaded due to insufficient space of the EFS partition is reduced. Thus, the terminal equipment can be connected with the wireless communication network through the loaded MBN file, and the functions of calling, surfing the Internet and the like are provided for the user.

It will be appreciated that the MBN files stored in the MCFG partition of the terminal device may include a plurality of generic profiles and a plurality of card-on-card profiles. The generic configuration file includes generic configuration information. The generic configuration files corresponding to different devices may be the same. For example, the generic profile may include dynamic spectrum sharing information, a waiting period for network congestion timeout packet drops, and the like. The terminal device will load all the generic configuration files. The card following configuration file comprises network configuration information corresponding to the terminal equipment. The card-along profile includes network configuration information corresponding to a subscriber identity module (Subscriber Identity Module, SIM) (or referred to as a SIM card) configured by the terminal device, such as network configuration information corresponding to a network operator including the SIM card. The card-following configuration file may also include network configuration information corresponding to a network operator where the SIM card is located. The card following configuration files corresponding to different devices are usually different according to the different wireless communication networks corresponding to the SIM cards configured by the different devices. For example, the on-card configuration file may include carrier frequencies corresponding to different regions, carrier aggregation combination information corresponding to different regions, and so on. And a plurality of card following configuration files corresponding to the devices are stored in the MCFG partition of the terminal device. The terminal equipment selects and loads the card following configuration file corresponding to the terminal equipment from the plurality of card following configuration files.

In the embodiment of the application, the terminal device may receive the OTA upgrade data packet sent by the server, so as to obtain the modem configuration file in the OTA upgrade data packet. The server side can respond to the configuration operation of the user, update at least one general configuration file and a plurality of card following configuration files in the modem configuration files, and send the updated modem configuration files to the terminal equipment. The updated modem configuration file does not include configuration information specific to some devices in at least one general configuration file, for example, network configuration information corresponding to a network operator where each device is located. And the configuration information specific to the devices is moved to the card-following configuration files corresponding to the devices.

In some implementations, the server moves configuration information corresponding to each of a plurality of devices in the non-updated modem configuration file to an existing card-following configuration file to obtain the updated modem configuration file. Or the server moves the configuration information corresponding to the devices in the non-updated modem configuration file to the newly created card-following configuration file to obtain the updated modem configuration file.

In one example, as shown in FIG. 3, take the example of a modem configuration file that is not updated in the server side including 1 generic configuration file and 5 card-following configuration files. The 1 general configuration file includes 10 pieces of configuration information. The 10 pieces of configuration information are configuration information 1, configuration information 2, configuration information 3, configuration information 4, configuration information 5, … …, and configuration information 10, respectively. Of these 10 pieces of configuration information, the configuration information 1 to the configuration information 5 are configuration information specific to the devices of the regions 1 to 5, respectively. The 5 card following profiles are card following profile 1, card following profile 2, card following profile 3, card following profile 4 and card following profile 5, respectively. The card following profiles 1 to 5 are corresponding to the devices in the regions 1 to 5, respectively.

And the server moves the configuration information corresponding to the plurality of devices in the non-updated modem configuration file to the existing card-following configuration file. Specifically, the server moves configuration information (i.e., configuration information 1) specific to the device in zone 1 in the general configuration file into the card following configuration file 1, moves configuration information (i.e., configuration information 2) specific to the device in zone 2 in the general configuration file into the card following configuration file 2, moves configuration information (i.e., configuration information 3) specific to the device in zone 3 in the general configuration file into the card following configuration file 3, moves configuration information (i.e., configuration information 4) specific to the device in zone 4 in the general configuration file into the card following configuration file 4, and moves configuration information (i.e., configuration information 5) specific to the device in zone 5 in the general configuration file into the card following configuration file 5, thereby obtaining an updated general configuration file and card following configuration file 1 to card following configuration file 5.

The updated general configuration file includes configuration information 6 to configuration information 10, and no longer includes configuration information 1 to configuration information 5. Configuration information 1 is added in the updated card following configuration file 1, configuration information 2 is added in the updated card following configuration file 2, configuration information 3 is added in the updated card following configuration file 3, configuration information 4 is added in the updated card following configuration file 4, and configuration information 5 is added in the updated card following configuration file 5.

It can be seen that 5 pieces of configuration information are reduced in the updated generic profile, while only 1 piece of configuration information is added to each card-following profile updated. And the server side sends the updated modem configuration file to the terminal equipment. In the configuration files received by the terminal equipment, the data volume of the general configuration files is greatly reduced, and the data volume loaded by the terminal equipment (such as loading 1 general configuration file and 1 card following configuration file) is also greatly reduced, so that the occupation of the memory space of the EFS partition by loading the MBN file is reduced.

In another example, as shown in fig. 4, take the example that the modem configuration file not updated in the server side includes 1 general configuration file and a card following configuration file 6. The 1 general configuration file includes 10 pieces of configuration information. The 10 pieces of configuration information are configuration information 1, configuration information 2, configuration information 3, configuration information 4, configuration information 5, … …, and configuration information 10, respectively. Of the 10 pieces of configuration information, part of the configuration information 1 to configuration information 5 is configuration information specific to the devices of the regions 1 to 5, respectively.

And the server moves the configuration information corresponding to the plurality of devices in the non-updated modem configuration file to the newly created card-following configuration file. Specifically, the server cuts out configuration information specific to the equipment in the region 1 from the configuration information 1 of the general configuration file, and generates the card following configuration file 1. The server cuts out the configuration information specific to the equipment in the region 2 from the configuration information 2 of the general configuration file, and generates the card-following configuration file 2. The server cuts out the configuration information specific to the equipment in the region 3 from the configuration information 3 of the general configuration file, and generates the card-following configuration file 3. The server cuts out the configuration information specific to the equipment in the region 4 from the configuration information 4 of the general configuration file, and generates the card-following configuration file 4. The server cuts out the configuration information specific to the equipment in the region 5 from the configuration information 5 of the general configuration file, and generates the card-following configuration file 5. The configuration information 1 to the configuration information 5 of the cut general configuration file no longer include configuration information specific to the devices of the regions 1 to 5. The card following configuration file 1 to the card following configuration file 5 are added after clipping.

It can be seen that, in the configuration information 1 to the configuration information 5 of the cut general configuration file, part of information is reduced, and 5 card following configuration files are added in the modem configuration file. The server side further sends the updated modem configuration file to the terminal equipment. In the modem configuration file received by the terminal equipment, the data volume of the general configuration file is greatly reduced, and the data volume loaded by the terminal equipment (such as loading 1 general configuration file and 1 card following configuration file) is also greatly reduced, so that the occupation of the memory space of the EFS partition by loading the MBN file is reduced.

In some possible implementations, the total data size of the plurality of general configuration files in the modem configuration files received by the terminal device and the card following configuration files corresponding to the terminal device is smaller than the preset data size. For example, the data size of the plurality of generic profiles is less than 2 megabytes. The preset data amount may be set according to the capacity of the second partition. For example, the preset amount of data is equal to 75% of the capacity of the second partition. If the second partition is 2.5 megabytes, the preset amount of data may be equal to 75% x 2.5 megabytes. In this way, the terminal device may reserve a part of the remaining space (e.g. reserve 15% of the capacity) in the second partition, so as to reduce the situation that the capacity of the second partition is exceeded during the process of loading the modem configuration file by the terminal device.

By way of example, the terminal device described in the embodiments of the present application may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (personal digital assistant, PDA), an augmented reality (augmented reality, AR) \virtual reality (VR) device, a media player, a wearable device, or the like.

It should be understood that the connection relationship between the modules illustrated in this embodiment is only illustrative, and does not limit the structure of the terminal device. In other embodiments, the terminal device may also include more or fewer modules than provided in the foregoing embodiments, and different interfaces or a combination of multiple interfaces may also be used between the modules in the foregoing embodiments.

In this embodiment, taking the cloud server 200 as shown in fig. 6 as an example, a hardware structure of the server is described. Fig. 6 is a hardware structure block diagram of a server side example provided in an embodiment of the present application. As shown in fig. 6, cloud server 200 includes a processor 222 that further includes one or more processors, and memory resources, represented by memory 232, for storing instructions, such as applications, executable by processor 222. The application program stored in memory 232 may include one or more modules each corresponding to a set of instructions. Further, the processor 222 is configured to execute instructions to perform the above-described methods.

Cloud server 200 may also include a power component 226 configured to perform power management of cloud server 200, a wired or wireless network interface 250 configured to connect cloud server 200 to a network, and an input-output interface 258. Cloud server 200 may operate an operating system based on storage memory 232.

The methods in the following embodiments may be implemented in a terminal device and a server having the above hardware structures. The method provided by the embodiment of the present application is described in an exemplary manner by taking an example that the terminal device is a mobile phone, the server is a cloud server, and the network configuration information corresponding to the network operator where the mobile phone is located includes carrier aggregation information. As shown in fig. 7, the method provided in the embodiment of the present application may include S701-S705.

S701, the cloud server responds to configuration operation of a user to configure a modem configuration file.

And the cloud server responds to the configuration operation of the user to configure the modem configuration file. The configuration operation is used for indicating the configuration of the modem configuration file, such as the configuration operation of clicking a configuration key by a user.

For example, the cloud server updates the unexpired modem configuration file to include a plurality of unexpired generic configuration files and a plurality of unexpired card-following configuration files in response to a configuration operation of a user. Taking a first general configuration file in a plurality of general configuration files not updated in the non-updated modem configuration file as an example, the first general configuration file (e.g. ltefeature ca. Xml) includes carrier aggregation information corresponding to devices in a plurality of regions respectively. In the unepdated modem configuration file, the data size (or file size) of the first generic configuration file is the first data size, e.g., equal to 250 kilobytes. The carrier aggregation information is used to indicate carrier combinations of available frequency bands for wireless communications. As shown in fig. 8, the first general configuration file includes carrier aggregation information corresponding to devices in regions 1 to 5, respectively. Taking carrier aggregation information corresponding to region 1 as an example, the carrier aggregation information indicates that devices in region 1 can use carrier combinations of frequency band 1, frequency band 2, and frequency band 3 to implement wireless communication.

And the cloud server modifies the first general configuration file in the non-updated modem configuration file to obtain the updated modem configuration file. For example, the cloud server may cut carrier aggregation information corresponding to the devices in the multiple regions from the first general configuration file, and generate a first card following configuration file corresponding to the devices in each region in the multiple regions. The card following configuration file corresponding to the equipment in each region comprises carrier aggregation information corresponding to the equipment in the region.

The updated modem configuration file comprises the first general configuration file after clipping and the first card following configuration files corresponding to the newly added devices in a plurality of areas respectively. The data size of the first generic profile after clipping is a second data size, which is smaller than the first data size. For example, the second amount of data is equal to 100 kilobytes.

Of course, the updated modem configuration file may further include other general configuration files other than the first general configuration file, and other card following configuration files other than the first card following configuration file.

S702, the cloud server sends an OTA upgrade data packet to the mobile phone, wherein the OTA upgrade data packet comprises a modem configuration file.

After the modem configuration file is configured by the cloud server, the modem configuration file is carried in an OTA upgrade data packet, and the OTA upgrade data packet is sent to the mobile phone. In a modem configuration file included in an OTA upgrade data packet sent by the cloud server to the mobile phone, the first general configuration file no longer includes carrier aggregation information corresponding to devices in a plurality of regions. The first card-following configuration file corresponding to the equipment in each region comprises carrier aggregation information corresponding to the equipment in the region.

S703, the mobile phone acquires the modem configuration file from the OTA upgrade data packet, and stores the modem configuration file in the first partition.

After receiving the OTA upgrading data packet issued by the cloud server, the mobile phone upgrades the software system of the mobile phone according to the OTA upgrading data packet. For example, after receiving the OTA upgrade data packet sent by the cloud server, the mobile phone can display prompt information to the user in the display interface, and the user can upgrade the software system of the mobile phone through the prompt information. And the mobile phone responds to the updating operation of the user and updates the software system according to the received OTA updating data packet. Or, the mobile phone automatically updates the software system according to the received OTA upgrading data packet in the idle period (such as 1 to 3 am) when the user has rest.

In the process of updating the software system, the mobile phone analyzes the OTA upgrade data packet to obtain a modem configuration file. Further, the mobile phone stores the modem configuration file in the first partition. The first partition is a storage area of the mobile phone for storing modem configuration files exclusively, and the first partition is the MCFG partition.

S704, the mobile phone is restarted automatically, and a plurality of general configuration files in the modem configuration files and card following configuration files corresponding to the mobile phone are loaded to the second partition in the restarting process.

After the update is completed, the handset will automatically restart to load the new configuration. In the restarting process, the mobile phone reads a plurality of general configuration files in the modem configuration files and card following configuration files corresponding to the mobile phone from the first partition to the second partition, so that the loading of the modem configuration files is realized. The second partition is a storage area for loading modem configuration files in the mobile phone, and the second partition is the EFS partition.

In the process of loading the modem configuration file, the mobile phone can firstly load a plurality of general configuration files in the modem configuration file. For example, a plurality of general configuration files in the modem configuration file are stored in a preset folder. For example, the preset folder is in the Default folder. The mobile phone can determine a first preset folder from a plurality of folders storing modem configuration files, and further read a plurality of general configuration files from the first preset folder.

If the mobile phone is identified to be provided with the SIM card in the restarting process, the international mobile subscriber identity (International Mobile Subscriber Identity, IMSI) of the SIM card can be obtained. The mobile phone can determine the folder storing the card following configuration file corresponding to the mobile phone from a plurality of folders storing the modem configuration file in the first partition according to the IMSI of the SIM card, and read the card following configuration file corresponding to the mobile phone in the folder. Further, the mobile phone loads the card following configuration file corresponding to the terminal equipment in the EFS partition.

For example, the IMSI of the SIM card includes a mobile country number (Mobile Country Code, MCC) and a mobile network code (Mobile Network Code, MNC). The folder in which the card configuration file is located has a corresponding relation with MCC and MNC. The mobile phone can acquire the card following configuration file corresponding to the area where the mobile phone is located in the corresponding folder. Further, the mobile phone loads the card following configuration file corresponding to the terminal equipment in the EFS partition.

In the process of loading a plurality of general configuration files and card following configuration files corresponding to the mobile phone in the second partition, if the first files of the first partition are different from the first files of the second partition, copying the first files in the second partition to obtain first temporary files. Further, the mobile phone modifies the first temporary file based on the first file in the first partition to obtain a modified first temporary file. And then the mobile phone replaces the first file in the second partition with the modified first temporary file. Thus, the loading of a plurality of general configuration files and the first files in the card-following configuration files corresponding to the mobile phone is realized.

It will be appreciated that the modem profile received by the handset does not vary much in total data volume as compared to the unepdated modem profile. The mobile phone only needs to load a plurality of general configuration files in the modem configuration files and the card following configuration files corresponding to the mobile phone, and all the card following configuration files do not need to be loaded. Whereas the generic profile in the modem profile is much less data-intensive than the generic profile in the not updated modem profile. Therefore, the data amount loaded by the mobile phone is reduced.

And S705, the mobile phone accesses the wireless communication network according to the general configuration file and the card following configuration file loaded in the second partition.

After the mobile phone loads the universal configuration file and the card following configuration file in the second partition, the mobile phone can be connected with the wireless communication network according to the loaded universal configuration file and the card following configuration file.

For example, the carrier aggregation information is included in the card-following configuration file. The handset may connect to the wireless communication network and communicate with the wireless communication network using a carrier combination indicated by the carrier aggregation information.

The following describes the procedure of accessing the mobile phone to the wireless communication network by taking the NV parameter included in the card-following configuration file of the mobile phone as an example. The NV parameter is used to indicate a preference for accessing the wireless communication network through the CS domain or the PS domain.

S905, the mobile phone sends an RRC connection setup complete message to the base station in response to the RRC connection setup message.

After receiving the RRC connection setup message, the base station may configure radio resources. After the configuration is completed, the mobile phone sends an RRC connection setup completion message to the base station, and notifies the base station that the radio resource is configured through the RRC connection setup completion message.

S906, the base station sends an initial message to the MME in response to the RRC connection setup complete message.

S907, the MME sends an initial context setup message to the base station.

And the MME responds to the initial message and establishes connection with the mobile phone authentication and security. The MME then sends an initial context setup message to the base station, which may be denoted as INITIAL CONTEXT SETUP REQUEST. The MME requests to establish a default bearer with the handset through an initial context setup message, providing the handset with a network protocol (Internet Protocol, IP) address at the time of the first connection.

S908, the base station sends a capability query message to the mobile phone in response to the initial context setup message.

The capability query message sent by the base station to the handset may be denoted UE Capacity Enquiry. The base station inquires the information of supportable frequency bands, bandwidths, carrier wave combinations and the like from the mobile phone through the capability inquiry message.

S909, the mobile phone returns capability information to the base station in response to the capability query message.

The mobile phone can acquire supportable capacity information such as frequency bands, bandwidths and the like from the loaded modem configuration information, and returns the inquired capacity information to the base station. The capability information may be noted as UE Capacity Information.

S910, the base station sends a capability information indication message to the MME.

After receiving the capability information of the mobile phone, the base station reports the capability information of the mobile phone to the MME through the capability information indication message. The capability information indication message may be noted as UE Capacity Info Indication. The MME may update capability information of the handset.

S911, the base station sends the security mode command to the mobile phone.

In order to provide the security of mobile phone communication, the base station instructs the mobile phone to start a security mode through a security mode command, and encrypts the transmitted data or signaling. The secure mode command may be denoted Security Mode Command.

S912, the mobile phone responds to the security mode command to activate the security mode and returns a security mode completion message to the base station.

The security mode complete message sent by the handset to the base station may be noted as Security Mode Complete. The mobile phone informs the base station to activate the security mode through a security mode completion message.

S913, the base station sends an RRC connection reconfiguration message to the mobile phone.

The RRC connection reconfiguration message sent by the base station to the handset may be denoted RRC Connection Reconfiguration. The base station instructs the handset to reconfigure the RRC connection through the RRC connection reconfiguration message. The base station carries an Attach Accept message (which may be denoted as Attach Accept) in the RRC connection reconfiguration message, informing the handset of the consent to access the wireless communication network. The mobile phone can preferably select the CS domain or the PS domain to connect with the wireless communication network according to the loaded NV parameters.

S914, the mobile phone responds to the RRC connection reconfiguration message and sends an RRC connection reconfiguration complete message to the base station.

The handset reconfigures the RRC connection in response to the RRC connection reconfiguration message. After the RRC connection reconfiguration is completed, the mobile phone returns an RRC connection reconfiguration completion message to the base station, and notifies the base station of the completion of the RRC connection reconfiguration through the RRC connection reconfiguration completion message. The RRC connection reconfiguration complete message may be noted as RRC Connection Reconfiguration Complete.

The uplink transmission message sent by the base station to the MME may be denoted UL NAS transport. The base station informs the mobile phone that the registration of the network is finished and the network attachment is finished through the uplink transmission message. The handset may then communicate with the wireless communication network through the base station.

If the handset does not normally load the NV parameters in the second partition, the handset defaults to using the CS domain to connect to the wireless communication network. However, if the base station indicates that the PS domain allows access through the RRC connection reconfiguration message in S913 described above, the mobile phone cannot access the wireless communication network in this case. In the above example, the general configuration file in the modem configuration file received by the mobile phone is cut, so that the data volume loaded by the mobile phone in the second partition is greatly reduced, and the NV parameters corresponding to the mobile phone can be loaded by the mobile phone. Thus, the mobile phone can access the wireless communication network to realize communication with the wireless communication network.

In some implementations, if the mobile phone detects that the remaining space of the second partition is insufficient during the process of loading the modem configuration file, the mobile phone deletes the temporary file in the second partition.

For example, in the process of loading the modem configuration file in the second partition, the mobile phone detects that the data volume to be loaded in the first partition is greater than the remaining space of the second partition, or the remaining space of the second partition is smaller than a preset capacity, such as less than 15% of the total capacity of the second partition. In this case, the handset considers that the remaining space of the second partition is insufficient. If the remaining space of the second partition is insufficient, determining the temporary file carrying the preset identifier (for example, carrying the preset identifier "$") in the second partition, and further deleting the temporary file carrying the preset identifier in the second partition.

In this way, the mobile phone can release the memory space of the second partition by deleting the temporary file under the condition that the remaining space of the second partition is insufficient, so that the memory space loaded with the modem configuration file exists in the second partition, the error reporting condition of the mobile phone is reduced, and the user experience is improved.
