In order to better understand the solution of the embodiment of the present application, the following description is made of terms and concepts related to the client identification module according to the embodiment of the present application.

(1) Identification code

The identification code of the subscriber identity module may be an ICCID, which is a unique identification number of the SIM card.

(2) Basic file information

The basic file information of the SIM may include an Elementary File (EF) of the SIM card. The specific information of the EF can be referred to in the following table.

It should be noted that the basic file information includes network information corresponding to different communication systems. For example, EF corresponding to 5G system_5GS3GPPLOCIEF corresponding to 4G system_EPSLOCIAnd the like. Therefore, when reading the basic file information, the highest level communication system supported by the electronic device 100 or the communication system corresponding to the RAN device of the cell in which the electronic device is located is determined, and then the related information corresponding to the communication system is read, so that the efficiency and effectiveness of reading the information can be improved.

(3) Prestoring frequency point

The pre-stored frequency point refers to the carrier frequency of the cell when the electronic device performs network registration last time.

(4) Pre-storing cell identification

The pre-stored cell Identity (cell ID) refers to an identification code of a cell when the electronic device performs network registration last time.

(5) Cell search

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a cell search process according to an embodiment of the present disclosure. As shown in fig. 3, a plurality of pre-stored frequency points registered by the electronic device last time are read first. And taking the frequency point with the strongest signal intensity in the plurality of prestored frequency points as a target frequency point. And then carrying out cell synchronous detection on the target frequency point to obtain a target cell. And otherwise, taking the frequency point with the strongest signal intensity in the frequency points which are not subjected to cell synchronous detection in the plurality of prestored frequency points as a target frequency point. And returning to execute the step of cell synchronous detection on the target frequency point. And if the target cell is not detected in the pre-stored frequency points, carrying out cell synchronous detection on the frequency points except the pre-stored frequency points in the full frequency band to obtain the target cell.

The cell synchronization detection process may include the following steps: receiving a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS) at a target frequency point, and acquiring slot and frame Synchronization, coarse frequency Synchronization, and Physical Cell Identification (PCI). After obtaining the PCI, the time slot and frequency fine synchronization can be obtained by adjusting the reference signal through the downlink common reference signal transmission structure.

It can be understood that searching for a synchronizable target cell according to the signal strength can improve the searching efficiency and the stability of the network signal. If all the pre-stored frequency points are traversed, and a target cell is not found, the position of the electronic equipment is changed, and cell search needs to be carried out on frequency points except the pre-stored frequency points in the full frequency band, so that network registration is realized.

(6) Network search information set

The network search information set comprises the information related to network search in the basic file information, pre-stored frequency points and pre-stored cell identifiers.

(7) Cell system information

The cell System Information is divided into a main System Information Block (MIB) and a plurality of basic System Information Blocks (SIBs). The MIB includes a limited number of the most important, most commonly used transmission information that needs to be obtained from the cell. SIBs may include SIB1-SIB12, e.g., SIB1 includes system information, timer and constant information used in idle and connected states. The SIB3 includes information of cell selection and reselection in an idle state, and calculates whether the camping condition is satisfied. The content of SIB4 is the same as SIB3, applicable to the connected state. The SIB5 includes configuration information for the common physical channel. The SIB6 is used for configuration information of the connected common and shared physical channels. The SIB7 includes rapidly changing information such as uplink interference and dynamic persistence values. The SIB11 includes measurement control information. The SIB12 is used for measurement control information in the connected state.

(8) Residential area camping

The cell camping refers to that the access layer of the electronic device 100 measures and tracks a target cell according to cell system information to determine whether the target cell is suitable for network registration. If the camping is successful, a registration stage is carried out. And if the camping fails, searching the target cell again. It should be noted that the cell camping in this application is regarded as successful.

(9) Cell camping information set

The cell camping information set may include information necessary to camp on the cell (e.g., the lowest signal strength) in the aforementioned cell system information. It will be appreciated that storing the necessary information for camping on a cell in the subscriber identity module may reduce the data to be stored.

Referring to fig. 4, fig. 4 is a flowchart illustrating a network registration method according to an embodiment of the present disclosure. As shown in fig. 4, after the electronic device is powered on, the electronic device initializes the sim module. And then entering a card reading stage 1, reading a target network search information set from the client identification module, and then entering a card reading stage 2 and a cell search stage. In the card reading stage 2, the registration information of the client identification module is read. In the cell searching stage, cell searching is carried out according to the target network searching information set obtained in the card reading stage 1, and a target cell which can be synchronous with the electronic equipment is obtained. And entering a cell camping stage, namely acquiring a target cell camping information set broadcasted to the target cell by the electronic equipment, and performing cell camping in the target cell according to the target cell camping information set. After the cell camping phase, entering a registration phase, that is, sending registration information to the access network equipment of the target cell, so as to perform network registration in the access network equipment.

Because the data reading in the SIM card can only be performed one by one, that is, the data in the card reading stage 1 and the card reading stage 2 can only be read one by one. In the prior art, the card reading phase 2 and the cell search phase are entered after the card reading phase 1 is finished. And after the card reading stage 2 and the cell camping stage are finished, registration is carried out according to the registration information obtained in the card reading stage 2. Therefore, a great amount of waiting time exists in the network registration process, which results in insufficient convenience of operation.

Based on this, in the embodiment of the present application, the ICCID, the network search information set, and the cell camping information set stored in the SIM card are stored in the memory 150. Therefore, the relevant information is read from the memory 150, the speed of cell camping can be improved, and the efficiency of network registration is improved. Optionally, the ICCID of the SIM card stores the network search information set and the cell camping information set of the SIM card. Further, the above information is stored in a Non-Volatile Memory (Non-Volatile Memory) in the Memory 150. Thus, the stability of data can be improved.

Therefore, when the target identification code is the same as the reference identification code, the client identification module is determined not to be replaced, network registration is carried out based on the network disconnection time and a network search set prestored in the electronic equipment, and the related information is not read from the client identification module one by one, so that the network registration efficiency can be improved.

In a possible example, if the target identifier is different from the reference identifier and the target operation is a power-on operation, the processor 140 is specifically configured to read a target network search information set pre-stored in the subscriber identity module; taking the target network search information set as the network search information set; performing cell search according to the network search information set to obtain a target cell; acquiring a target cell camping information set of the target cell and reading the registration information of the client identification module; performing cell camping in the target cell according to the target cell camping information set; and sending the registration information to the access network equipment of the target cell to complete network registration.

In a possible example, if the target operation is an operation exiting from a flight mode, and the network search information set includes a pre-stored frequency point, the processor 140 is specifically configured to, if the network outage duration is smaller than a second threshold value, perform cell search according to the pre-stored frequency point to obtain a target cell, and read a pre-stored cell camping information set and registration information of the client identification module; performing cell camping in the target cell according to the cell camping information set; and sending the registration information to the access network equipment of the target cell to complete network registration.

The above is merely an example, the electronic device 100 further includes sensors such as an electronic compass, a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, input and output interfaces such as an audio input interface, a serial port, a keyboard, a speaker, and a charging interface, and modules not shown such as a camera and a bluetooth module, which are not limited in this application. The following describes embodiments of the present application in detail.

Referring to fig. 5, fig. 5 is a flowchart illustrating a network registration method according to an embodiment of the present disclosure. As shown in fig. 5, the present network registration method is applied to an electronic device. It should be noted that the method is implemented on the premise that the electronic device includes at least one client identification module. When the electronic device includes a plurality of client identification modules, network registration may be performed in sequence according to priorities of the client identification modules. The method comprises steps S501-S503:

s501: and if the electronic equipment is detected to execute the target operation, reading a target identification code of a customer identification module in the electronic equipment.

In this embodiment of the application, the target operation may be a power-on operation, an exit from an airplane mode operation, an operation of starting a data network, or an operation of switching the data network, and the like, which is not limited herein. The target identification code is the identification code of a client identification module inserted into the electronic equipment and can be read from the client identification module.

S502: and if the target identification code is the same as the reference identification code, determining the network disconnection time of the electronic equipment, and reading a pre-stored network search information set.

In the embodiment of the application, the reference identification code is the identification code of the client identification module when the electronic device last registered on the network, and can be read from the memory of the electronic device.

As described above, after the subscriber identity module performs network registration, the network search information set and the cell camping information set registered this time may be stored. In addition, the IMSI, the PIN, the PUK, and the storage space used by the user may also be stored, and are not limited herein.

In the embodiment of the application, when the target operation is a power-on operation, the network disconnection duration is a duration from power-off to power-on of the electronic device. When the target operation is the operation of exiting the flight mode, the network disconnection time length is the time length from entering the flight mode to exiting the flight mode.

It will be appreciated that the target identification code is the same as the reference identification code, indicating that the customer identification module has not been replaced. Therefore, the cell search can be performed based on the network search information at the last registration.

S503: and performing network registration according to the network disconnection time and the network search information set.

The present application does not limit the network registration process, and in a possible example, step S503 includes the following five cases, where:

firstly, if the target operation is a starting operation and the network disconnection time length is less than a first threshold value, carrying out cell search according to the network search information set to obtain a target cell; acquiring a target cell camping information set of the target cell and reading the registration information of the client identification module; performing cell camping in the target cell according to the target cell camping information set; and sending the registration information to the access network equipment of the target cell to complete network registration.

The steps of cell search and cell camping may refer to the aforementioned definition description, and are not described herein again.

The first threshold is used to determine whether the location of the electronic device has changed. The first threshold is not limited in the present application, and may be determined according to a moving speed of the electronic device, that is, the faster the moving speed is, the smaller the first threshold is. For example, the power-on operation is performed immediately after the user inadvertently powers off the device. Or system failure, automatic restart. The first situation is satisfied because the network outage duration is extremely short under the above conditions.

Optionally, the registration information of the client identification module is read according to the network type of the target cell.

It will be appreciated that different network types correspond to different access technologies. Therefore, the registration information is read from the first subscriber identification module according to the network type of the target cell, and the reading efficiency of the registration information can be improved. And the registration information is information related to the network type, so that the effectiveness of the registration information can be improved.

Referring to fig. 6A, after the electronic device is powered on, the electronic device initializes the client identification module. A cell search phase is entered during initialization, i.e. a cell search is performed based on a set of network search information pre-stored in the electronic device. After the target cell is obtained by searching, entering a cell camping stage, namely obtaining a target cell camping information set of the target cell, and then performing cell camping in the target cell according to the target cell camping information set. After the initialization phase is finished, a card reading phase 2 is entered, and the card reading phase 2 can read the registration information from the customer identification module. After the cell camping stage is finished, entering a registration stage, namely sending registration information to the access network equipment of the target cell.

It can be seen that, in the first case, the target identification code is the same as the reference identification code, and the network disconnection duration is less than the first threshold, it can be determined that the electronic device has not been replaced with the customer identification module, and the location of the electronic device has not changed. Therefore, the cell search is carried out according to the network search information set prestored in the electronic equipment without waiting for the reading of the target network search information set in the card reading stage 1, so that the cell search efficiency is improved, and the network registration efficiency is improved conveniently.

Secondly, if the target operation is a starting operation and the network disconnection time is greater than or equal to the first threshold value, cell search is carried out according to the network search information set, and a target network search information set prestored in the client identification module is read; if the target network searching information set is different from the network searching information set, carrying out cell searching according to the target network searching information set to obtain a target cell; acquiring a target cell camping information set of the target cell; performing cell camping in the target cell according to the target cell camping information set; and sending registration information to the access network equipment of the target cell to complete network registration.

The comparison method between the target network search information set and the network search information set can perform comparison one by one according to the information identifier of each network search information, where the information identifier is used to describe the information type of the network search information, for example: EF_AD、EF_NETPAR、EF_ACCAnd the like. And when the target network search information set is inconsistent with one item of network search information in the network search information set, determining that the target network search information set is different from the network search information set.

In the second case, the target identification code is the same as the reference identification code, and the network disconnection time is greater than or equal to the first threshold value, which indicates that the position of the electronic equipment may be changed. For example, after the electronic device is powered off, the user returns to the second address from the first address to charge, and then the electronic device is powered on. The network disconnection time from the first address to the second address is larger than a first threshold value, and the position of the electronic equipment is changed.

Referring to fig. 6B, after the electronic device is powered on, the electronic device initializes the client identification module. And entering a cell search phase during initialization, namely performing cell search according to a network search information set prestored in the electronic equipment. And during the cell search, entering a card reading stage 1, namely reading target network search information prestored in the client identification module. If the network search information corresponding to the information identifier of the target network search information in the network search information set is not consistent with the network search information corresponding to the information identifier of the target network search information in the network search information set, after the target network search information set is obtained in the card reading stage 1, the cell search stage is entered again according to the target network search information set, and the card reading stage 2 is entered. Entering a cell camping stage after the cell searching stage, namely acquiring a target camping cell information set of a target cell, and performing cell camping in the target cell according to the target camping cell information set. And after the cell is camped, entering a registration stage according to the registration information read in the card reading stage 2.

It can be seen that, in the second case, if the target identification code is the same as the reference identification code, the network disconnection time is greater than or equal to the first threshold, and the target network search information set is different from the network search information set, it indicates that the location of the electronic device has changed. Therefore, it is not appropriate to refer to a network search information set stored in the electronic device. After the card reading stage 1, the target network search information set obtained in the card reading stage 1 is used as a network search information set, and cell search is performed according to the network search information set to obtain a target cell. And performing cell camping based on the target cell camping information set broadcasted in the target cell. And then the registration is completed according to the registration information obtained in the card reading stage 2, so that the registration accuracy can be improved.

Thirdly, if the target operation is a starting operation and the network disconnection time length is greater than or equal to the first threshold value, cell search is carried out according to the network search information set, and a target network search information set prestored in the client identification module is read; if the target network searching information set is the same as the network searching information set, taking the cell obtained by cell searching as a target cell; acquiring a target cell camping information set of the target cell; performing cell camping in the target cell according to the target cell camping information set; and sending registration information to the access network equipment of the target cell to complete network registration.

When the target network search information set and the network search information set are consistent, the target network search information set and the network search information set are determined to be the same, and the fact that the position of the electronic equipment is not changed is indicated. For example, the user turns off the electronic device before sleeping at night, and the off-network duration is greater than the first threshold value due to long sleeping time. In this case, the customer identification module of the electronic device is not replaced, and the position of the electronic device is not changed.

Referring to fig. 6C, a cell search phase is entered during initialization, that is, cell search is performed according to a network search information set pre-stored in the electronic device. And entering a card reading stage 1 during the cell search, namely reading a target network search information set prestored in the client identification module. After the card reading stage 1, if it is determined that the target network search information set is the same as the network search information set, entering a cell camping stage after the cell search stage, namely acquiring a target camping cell information set of a target cell, and performing cell camping in the target cell according to the target camping cell information set. And after the cell camping stage, entering a registration stage, namely completing registration according to the registration information obtained in the card reading stage 2. It should be noted that, the network type of the target cell can be obtained in the cell search stage, so that the registration information can be read in the card reading stage 2 according to the network type, and the validity of the registration information is improved. And all data reading in the card reading stage 2 is not required to be finished, and after the cell camping stage, the registration stage can be entered according to the registration information, so that the registration efficiency is improved.

In a third case, if the target identification code is the same as the reference identification code, the network disconnection time is greater than or equal to the first threshold, and the target network search information set is the same as the network search information set, it indicates that the position of the electronic device has not changed. Therefore, in this case, a cell obtained by performing a cell search based on the network search information set is used as the target cell. After the registration information is read and the cell camping is finished, network registration can be performed according to the registration information without waiting for completion of data reading in the card reading stage 2, so that the network registration efficiency is improved.

Fourthly, if the target operation is the operation of exiting the flight mode and the network disconnection time length is greater than or equal to a second threshold value, carrying out cell search according to the network search information set to obtain a target cell; acquiring a target cell camping information set of the target cell; reading the registration information of the client identification module; performing cell camping in the target cell according to the target cell camping information set; and sending the registration information to the access network equipment of the target cell to complete network registration.

The second threshold is similar to the first threshold and is also used for judging whether the position of the electronic equipment is changed.

For example, the flight mode is entered during a user's meeting and exited after the meeting is completed. The fifth case is satisfied because the duration of the flight mode in the above case is greater than the second threshold.

Referring to fig. 6D, when exiting the flight mode, the network search information set is read first, and then the cell search stage is entered, that is, the cell search is performed according to the network search information set to obtain the target cell. And entering a cell camping stage, namely acquiring a target cell camping information set of the target cell, and performing cell camping in the target cell according to the target cell camping information set. After the cell camping phase, entering a registration phase. It should be noted that the step of reading the registration information may be performed at any stage before the registration stage, and is not limited herein.

In a fourth case, it is determined that the position of the electronic device is changed if the target operation is the exit flight mode operation and the network disconnection duration is greater than or equal to the second threshold. Therefore, in this case, since the electronic device is not turned off, it is not necessary to search the network information of the client identification module inserted in the electronic device again, and the cell search is performed based on the network search information set at the time of the last registration, which can improve the efficiency of the cell search and facilitate the improvement of the network registration efficiency.

Fifthly, if the target operation is an operation of quitting a flight mode, the network search information set comprises a prestored frequency point, and the network disconnection time is less than a second threshold value, cell search is carried out according to the prestored frequency point to obtain a target cell, and a prestored cell camping information set and registration information of the customer identification module are read; performing cell camping in the target cell according to the target cell camping information set; and sending the registration information to the access network equipment of the target cell to complete network registration.

For example, the flight mode may be touched to exit the flight mode immediately after the user inadvertently touches a component corresponding to the flight mode. The fifth case is satisfied because the time to exit the flight mode is extremely short in the above case.

And when the client identification module of the electronic equipment is not replaced and the network disconnection time is less than a second threshold value, determining that the position of the electronic equipment is not changed. Referring to fig. 6E, when exiting the flight mode, the network search information set, the cell camping information set, and the registration information of the subscriber identity module, which are pre-stored in the electronic device, are read first, and then a cell search stage is entered, i.e., cell search is performed according to pre-stored frequency points in the network search information set, so as to obtain a target cell. And entering a cell camping stage, and performing cell camping in the target cell according to the cell camping information set. Compared with the fourth case, the efficiency of cell search is improved, and the network registration efficiency is further improved.

In the method shown in fig. 5, when the target identification code is the same as the reference identification code, it is determined that the client identification module is not replaced, and network registration is performed based on the network disconnection time and a network search set pre-stored in the electronic device, instead of reading related information from one of the client identification modules, so that the network registration efficiency can be improved.

In one possible example, the method further comprises: if the target identification code is different from the reference identification code and the target operation is a starting operation, reading a target network search information set prestored in the client identification module; performing cell search according to the target network search information set to obtain a target cell; acquiring a target cell camping information set of the target cell; performing cell camping in the target cell according to the target cell camping information set; reading the registration information of the client identification module; and sending registration information to the access network equipment of the target cell to complete network registration.

This example can be described with reference to fig. 4, that is, when the target identification code is different from the reference identification code, it is determined that the client identification module has been replaced, and the network registration adopts a network registration method in a conventional booting operation, which can improve the accuracy of network registration.

In one possible example, the method further comprises: if the target identification code is different from the reference identification code and the target operation is the operation of exiting from the flight mode, reading the registration information of the client identification module; performing cell search according to the network search information set to obtain a target cell; acquiring a target cell camping information set of the target cell; performing cell camping in the target cell according to the target cell camping information set; and sending the registration information to the access network equipment of the target cell to complete network registration.

In this example, reference may be made to the description of the fourth case, that is, when the target identification code is different from the reference identification code, it is determined that the client identification module is replaced, and the network registration adopts a conventional network registration method when the aircraft exits from the flight mode, so that the accuracy of network registration may be improved.
