SIM card for voice service.

In some embodiments, the data card may specifically be an IoT card provided by a network operator. The IoT card (also known as the IoT card) is a SIM card provided by the network operator for the networking of intelligent terminal devices. The IoT card generally only supports data services and does not support voice services.

As shown in FIG. 2a, when the ordinary card is inserted into the electronic device 100, the electronic device 100 initiates registration with the 5G network. After the registration is successful, the electronic device 100 resides on the 5G network and provides data services and voice services for users based on the 5G network.

As shown in FIG. 2b, when the data card is inserted into the electronic device 100, the electronic device 100 initiates registration with the 5G network. Since the data card does not support voice services, the 5G network reports to the electronic device 100 that the data service registration is successful and the voice service registration fails. , and the electronic device 100 is configured as Voice Centric. Therefore, after receiving the voice service registration failure message, the electronic device 100 disconnects from the 5G network and presents a state of no service.

In response to the above problems, an embodiment of the present application provides a method for network registration, and the method may be specifically executed by the electronic device 100 shown in FIG. 1 .

An application scenario of the above network registration method can be seen in FIG. 3 . After the data card is inserted into the electronic device 100, the electronic device 100 initiates registration with the 5G network. Since the data card does not support voice services, the 5G network feeds back to the electronic device 100 a message that the data service registration is successful and the voice service registration fails.

After receiving the aforementioned message, the electronic device 100 recognizes that the SIM card to be registered is a data card, modifies its configuration from Voice Centric to Data Centric, and initiates registration to the 5G network again, and the 5G network still reports The data service registration is successful, and the voice service registration fails. However, at this time, the configuration of the electronic device 100 is DataCentric. After receiving the feedback message, the electronic device 100 can reside on the 5G network and provide data services to users based on the 5G network.

The operating system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. Referring to FIG. 5 , the embodiment of the present application uses an Android system with a layered architecture as an example to illustrate the software architecture of the electronic device 100 as an example.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, which are, from top to bottom, an application layer, an application framework layer, an Android runtime (Android runtime) and system libraries, and a kernel layer.

The application layer can include a series of application packages. As shown in Figure 5, the application package can include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message and so on. For example, in this embodiment of the present application, the application package may further include a smart home. During scene orchestration, smart home applications can access the scene orchestration interface management service provided by the application framework layer.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for the applications of the application layer. The application framework layer includes some predefined functions. As shown in Figure 5, the application framework layer may include window managers, content providers, view systems, telephony managers, resource managers, notification managers, and the like.

The notification manager enables applications to display notification information in the status bar, which can be used to convey notification-type messages, and can disappear automatically after a brief pause without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also display notifications in the status bar at the top of the system in the form of graphs or scroll bar text, such as notifications of applications running in the background, and notifications on the screen in the form of dialog windows. For example, text information is prompted in the status bar, a prompt sound is issued, the electronic device vibrates, and the indicator light flashes.

In this embodiment, the notification manager may be used to prompt the user that the SIM card that needs to be registered supports only data services but not voice services.

Android Runtime includes core libraries and a virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one is the function functions that the java language needs to call, and the other is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, safety and exception management, and garbage collection.

A system library can include multiple functional modules. For example: surface manager (surface manager), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL) and so on.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display drivers, camera drivers, audio drivers, and sensor drivers.

It should be noted that although the embodiments of the present application are described by taking the Android system as an example, the basic principles thereof are also applicable to electronic devices based on operating systems such as iOS, Windows, and Hongmeng.

Referring to FIG. 6 , the method for network registration provided by the embodiment of the present application may specifically include the following steps:

S601, a modem processor detects a registration initiation condition.

The registration initiation condition may have various forms, which are not limited in this embodiment.

Exemplarily, the registration initiation condition may be that the SIM card is powered on. The modem processor can be connected to the SIM card interface shown in Figure 1. When the SIM is powered on, the SIM card can send a message to the modem processor through the SIM card interface shown in Figure 1 to instruct the SIM card to power on. If the modem processor receives this interrupt signal, it is equivalent to detecting that the SIM card is powered on.

The SIM card is powered on when the user inserts the SIM card into the electronic device 100 that is turned on. When the SIM card is inserted into the electronic device 100 that is turned on, the newly inserted SIM card is the SIM card that needs to be registered this time.

The SIM card is also powered on when the electronic device 100 with the SIM card inserted is turned on. At this time, the SIM card inserted into the electronic device 100 is the SIM card that needs to be registered this time. When the electronic device 100 has inserted multiple SIM cards, each of which is a SIM card that needs to be registered, the electronic device 100 can sequentially complete the registration of each SIM card by executing the method of this embodiment.

Exemplarily, the registration initiation condition may also be that the electronic device 100 exits the airplane mode. Current electronic devices, especially smartphones, are generally configured with an airplane mode and a normal operation mode, and such electronic devices can switch between the airplane mode and the normal operation mode in response to user operations. When the electronic device 100 enters the airplane mode, the modem processor of the electronic device 100 will be disabled. When the electronic device 100 exits the airplane mode, that is, switches from the airplane mode to the normal working mode, the application framework enables the modem process. After receiving the information indicating the activation, the modem processor can determine that the electronic device 100 exits the airplane mode. When the electronic device 100 exits the airplane mode, the SIM card inserted into the electronic device 100 at this time is the SIM card that needs to be registered this time.

Exemplarily, the registration initiation condition may also be that the electronic device 100 enters another cell from one cell. When the electronic device 100 switches from one cell to another, the application framework can send information to the modem processor to explain the cell switching, and the modem processor can determine that the electronic device 100 has switched from one cell to another after receiving the information. cell into another cell.

When the registration initiation condition is cell switching, the SIM card in the electronic device 100 that undergoes cell switching is the SIM card that needs to be registered this time.

In some embodiments, after each time the application framework determines whether a SIM card is a data card, the determination result may be recorded in the internal memory of the electronic device 100 . These judgment results may be specifically recorded in various forms, and the specific recording form is not limited in this embodiment. For example, these judgment results can be recorded in the form of a list as shown in Table 1 below:

Table 1

Identity card type ICCID-1 data card ICCID-2 regular card

In Table 1, ICCID-1 and ICCID-2 represent the ICCIDs of SIM card 1 and SIM card 2, respectively. The second row of Table 1 represents that SIM card 1 is a data card, and the third row represents that SIM card 2 is a common card. In some embodiments, the MSISDN, IMSI or other information of the SIM card may also be used as the identity identifier of each SIM card, which is not limited in this embodiment.

Based on the judgment result recorded in the internal memory, after the modem processor detects the registration initiation condition, it can use the ICCID of the SIM card to be registered to find out whether there is a SIM card to be registered in the above judgment result. If there is a SIM to be registered in the above judgment result, and the SIM card to be registered is a data card, the modem processor may execute step S611. If there is no SIM card that needs to be registered in the above judgment result, or there is a SIM card that needs to be registered in the above judgment result, and the SIM card to be registered is a common card, the modem processor executes step S602. S602, the modem processor sends the registration information centered on the voice to the target network.

The above registration information is used to request registration to the target network.

In this embodiment, the target network may be a 4G network, for example, an Evolved Packet System (Evolved Packet System, EPS) network, or a 5G network.

When the target network is a 4G network, the above registration information may specifically be an attach request (attach request). When the target network is a 5G network, the above registration information may specifically be a registration request (Registration request).

The attach request may include multiple fields, and the specific content of the attach request is not limited in this embodiment.

Exemplarily, the attach request may include an attach type field, and a voice domain preference and user setting (voice domain preference and UE's usage setting) field.

The attach type field is used to describe the type of the attach request, and different field values of this field correspond to different types of attach requests. When represented in binary, if the field value of the attach type is 001, the corresponding attach request is an Evolved Packet System (EPS) request (EPS attach). If the field value of the attach type is 010 or 011, the corresponding attach request is The attach request is a combined EPS/IMSI attach request. If the value of the attach type field is 100, the corresponding attach request is an emergency attach request (Emergency attach).

The EPS attach request is used to register the EPS network, the EPS network is used to provide data services and voice over Long-Term Evolution (Voice over Long-Term Evolution, VoLTE) services for electronic equipment, and the IMSI attach request is used to register Circuit Switched (Circuit Switched, CS) network, the CS network is used to provide voice services.

The attach request in step S602 may be a joint attach request.

The voice domain preference and user settings fields occupy one byte, with a total of 8 binary bits, of which the values of the first and second binary bits are used to indicate the voice domain preference, and the value of the third binary bit is used to indicate the user Settings (UE's usagesetting), user settings include voice-centric (Voice Centric) and data-centric (DataCentric). If the third binary bit in the voice domain preference and user settings field is equal to 0, it means that the user is set to VoiceCentric; the third binary bit of the voice domain preference and user settings field is equal to 1, it means that the user is set to DataCentric.

The registration request may include a user setting (UE's usage setting) field, and the value of the first binary digit of this field is used to indicate Voice Centric or Data Centric. Specifically, the first binary digit of the user setting field is 0, indicating that the registration request is a Taking voice as the center, the first binary bit of the user setting field is 1, indicating that the registration request is data-centric.

S603, the modem processor receives the message fed back by the target network.

When the target network is a 4G network, the messages fed back by the target network may include an attach accept message (attachaccept) and an activate default EPS bearer context request message (Activate default EPS bearer contextrequest Msg). In some embodiments, the target network may also feed back other messages, and the content of the messages fed back by the target network is not limited in this embodiment.

The Attach Accept message may include an Attach result field and Network feature support. When the SIM card of the electronic device 100 is a data card, the attach accept message is used to explain to the electronic device 100 that the target network only supports data services and does not support voice services.

Exemplarily, when the target network is a 4G network and the SIM card of the electronic device 100 is a data card, the value of the Attach result field in the attach acceptance message is 1, and the value of the first binary digit in the Network feature support field is 0.

The field value of the Attach result field is 1, indicating that the EPS registration of the target network is successful, and the IMSI registration fails, and the failure of the IMSI registration indicates that the target network does not support Circuit Switched Fallback (CSFB). The first binary bit in the Network feature support field is used to indicate whether the target network supports voice over Packet Switched Domain (IMS voice over Packet Switched Domain, IMSVoPS). IMS is the abbreviation of IP Multimedia Subsystem. If it is 0, it means that the target network does not support IMSVoPS. CSFB and IMSVoPS are the two main ways for 4G networks to provide voice services. When the target network does not support CSFB and IMSVoPS, it means that the target network does not support voice services, that is to say, the electronic device 100 fails to register for voice services, and the electronic device 100 cannot The target network implements voice calls.

The activation default EPS bearer context request message (hereinafter referred to as the context request message) may carry an access point name (Access Point Name, APN). In some embodiments, the application framework can use the APN obtained from the context request message to determine whether the SIM card to be registered is a data card.

When the target network is a 5G network, the message fed back by the target network may include a registration accept message (Registration accept). The registration acceptance message may include a 5G network feature support (5GS network feature support) field. The function of the first binary digit of the 5GS network feature support field is the same as the function of the first binary digit of the Network feature support field, and will not be repeated here.

S604, the modem processor sends the registration failure information to the application framework.

What the electronic device 100 sends is a voice-centric attachment request. According to the stipulations of the relevant 3GPP protocols, when the voice-centric electronic device fails to register for the voice service in the target network, the electronic device cannot register with the target network and reside in the target network. target network. Therefore, after receiving the message that the target network only supports data services and does not support voice services, the modem processor can determine that the registration with the target network fails, and then sends information to the application framework for explaining the registration failure.

S605, the modem processor sends a registration end message to the target network.

When the target network is a 4G network, the registration end message may specifically be an attach complete message (Attachcomplete Msg). When the target network is a 5G network, the registration end message may specifically be a registration complete message (Registration complete Msg).

In some embodiments, the modem processor may also send a registration end message to the target network first, and then send a registration failure message to the application framework. This embodiment does not limit the execution order of step S604 and step S605.

The registration end message is used to indicate the end of the registration process. In this embodiment, the registration process includes steps S602, S603 and S605.

S606, the application framework reads the type information of the SIM card to be registered.

The type information of the SIM card to be registered refers to the information that can distinguish whether the SIM card to be registered is a data card. This embodiment does not limit the specific content of the type information of the SIM card.

Exemplarily, the type information of the SIM card to be registered may include the MSISDN, IMSI, and ICCID of the SIM card to be registered, and the Access Point Name (APN) fed back by the target network after receiving the attach request. In step S606, the application framework may read any one or more of the foregoing type information. Among them, the MSISDN, IMSI and ICCID of the SIM card can be used as the identity identifier of the SIM card.

It should be noted that the APN included in the type information refers to the APN carried in the message fed back by the target network. Specifically, the context request message fed back by the target network may carry the APN.

In some embodiments, after receiving the context request message, the modem processor may pass the context request message to the application framework, and the application framework parses the context request message to obtain the APN carried therein.

In some embodiments, the modem processor may also parse the received context request message, obtain the APN carried in the context request message, and then pass the obtained APN to the application framework.

When sending the registration failure information in step S604, the modem processor may send the context request message or the APN obtained by parsing to the application framework together. Alternatively, the modem processor may send the context request message or the parsed APN to the application framework when the application framework needs to read the type information.

In step S606, the application framework may read the MSISDN, IMSI and ICCID of the SIM card from the SIM card or the internal memory of the electronic device 100, and the specific storage location of these information is not limited in this embodiment.

Exemplarily, the application framework can directly access the SIM card of the electronic device 100, and read the MSISDN, IMSI and ICCID of the SIM card from the SIM card. Alternatively, after the SIM card is powered on, the MSISDN, IMSI and ICCID stored in the SIM card can be copied to the internal memory of the electronic device 100, so that in S606, the application framework can read in the internal memory of the electronic device 100 Get the MSISDN, IMSI and ICCID of the SIM card.

The MSISDN generally includes a country code (Country Code, CC), a national destination code (National Destination Code, NDC) and a subscriber number (Subscriber Number, SN), where the NDC can also be called the number segment of the MSISDN.

The CC is used to distinguish different countries, and is generally fixed to the first two digits of the MSISDN, the SN is generally fixed to the last eight digits of the MSISDN, and the length of the NDC is variable. The part of the MSISDN that removes the country code is the so-called telephone number or mobile phone number. For example, the part of the MSISDN of a SIM card after removing the country code can be 144XXXX1111.

The ICCID generally consists of 20 digits and is used to uniquely identify each SIM card. For different network operators, the coding rules of ICCID will be different to some extent.

Exemplarily, the ICCID of the SIM provided by a certain network operator may be represented as: 898600MFSSYYGXXXXXXP.

Among them, the first and second digits from the left, namely "89", represent the international number, the third and fourth digits represent the country number, "86" represents China, and the fifth and sixth digits are the carrier number. , used to indicate a specific operator. M represents the number segment of the phone number of the SIM card (generally the first three digits of the phone number are called the number segment of the number), and the value of M corresponding to different number segments is different. F is the fourth digit of the phone number of the SIM card. SS is the serial number of the administrative region, YY is the last two digits of the year in which the ICCID was compiled, G is the serial number of the SIM supplier, X...X is the user identification code, and P is the check code.

The IMSI is generally composed of 15 digits and is used to distinguish different users in the cellular network. IMSI can generally be divided into three parts, namely Mobile Country Code (MCC), Mobile Network Code (MNC) and Mobile Subscriber Identification Number (MSIN).

Among them, the MCC is uniformly distributed and managed by the International Telecommunication Union (ITU) around the world, and is used to uniquely identify the country to which the mobile user belongs, with a total of 3 digits.

The MNC is used to identify the mobile communication network to which the mobile user belongs, and is generally composed of 2 to 3 digits. When there are multiple operators in the same country, these operators can be distinguished by MNC.

MSIN is used to identify mobile users in a certain mobile communication network and generally contains 10 digits.

S607, the application framework reads the characteristic information of the data card.

Data card feature information, used to indicate the features of the data card.

In different implementations, the data card feature information may have different forms and contents, and the embodiments of the present application do not limit the specific form and content of the data card feature information.

Exemplarily, the data card feature information may be one or more lists, or the data card feature information may be one or more specific value ranges.

The data card feature information may be pre-stored in the internal memory of the electronic device 100 when the electronic device 100 leaves the factory. Meanwhile, the electronic device 100 may update the data card feature information stored in the internal memory through the network during use. Correspondingly, in step S607 , the application framework may read the data card feature information from the memory of the electronic device 100 .

In some optional embodiments, the application framework may also execute step S607 first, and then execute S606. This embodiment does not limit the execution order of steps S606 and S607.

S608, the application framework determines whether the SIM card is a data card.

If the SIM card to be registered is a data card, step S609 is performed.

The application framework can compare the type information of the current SIM with the characteristic information of the data card, so as to determine whether the SIM card to be registered is a data card. According to the difference between the type information and the feature information of the data card, the specific comparison method in step S608 is also different, which is not limited in this embodiment.

In some embodiments, the type information read by the application framework may include the MSISDN of the SIM card to be registered. Correspondingly, the data card feature information may be the length of the MSISDN of the data card; or, the MSISDN of the data card. number segment; or, a list consisting of the MSISDNs of multiple data cards.

Exemplarily, when the data card feature information is the length of the MSISDN of the data card, the specific implementation of step S608 may be that the application framework first identifies the length of the MSISDN of the SIM card that needs to be registered, that is, identifies the SIM card that needs to be registered. How many digits does the MSISDN contain, and then compare the length of the MSISDN of the SIM card to be registered with the length of the MSISDN of the data card in the data card feature information. If the two are consistent, the type information and the data card feature information match. If the two are inconsistent, it means that the type information and the data card feature information do not match.

For example, the length of the MSISDN of the data card can be 13 digits. If the application framework identifies that the MSISDN of the SIM card that needs to be registered consists of 13 digits, it means that the type information matches the data card feature information. The MSISDN of the registered SIM card does not consist of 13 digits, indicating that the type information and data card feature information do not match.

Exemplarily, when the feature information of the data card is the number segment of the MSISDN of the data card, the specific implementation of step S608 may be that the application framework extracts the number segment of the MSISDN of the SIM card, and then extracts the number segment and data from the SIM card. Compare the number segment included in the card feature information. If the number segment of the MSISDN of the SIM card is consistent with any number segment in the feature information of the data card, it indicates that the type information matches the feature information of the data card, and the SIM card is a data card; if the number segment of the MSISDN of the SIM card matches the feature information of the data card Each number segment in the information is different, indicating that the type information and data card feature information do not match, and the SIM card is not a data card.

For example, the data card feature information includes three number segments 10646, 10647 and 10648. If the number segment extracted by the application framework from the MSISDN of the SIM card is 10647, it indicates that the SIM card is a data card. If the number segment extracted by the application framework is 10647 The number segment does not belong to these three number segments, indicating that the SIM card is not a data card.

Exemplarily, when the data card feature information is a list composed of MSISDNs of multiple data cards, in step S608, the application framework can directly look up the MSISDNs of the SIM cards that need to be registered in this list. The MSISDN of the registered SIM card indicates that the type information matches the data card feature information, and the SIM card is a data card; if the MSISDN of the SIM card to be registered is not found in the list, it indicates that the type information does not match the data card feature information, and the SIM card is a data card. A SIM card is not a data card.

In some embodiments, the type information read by the application framework may include the ICCID of the SIM card that needs to be registered. Correspondingly, the data card feature information may include one or more ICCID intervals, or may include multiple data records. List of ICCIDs for the card.

Exemplarily, if the data card feature information includes one or more ICCID intervals, the specific implementation of step S608 may be that the application framework determines whether the ICCID of the SIM card to be registered is located in these intervals, if the ICCID of the SIM card is located in the interval. In a certain interval, it means that the type information and data card feature information match, and the SIM card is a data card. If the ICCID of the SIM card is not located in any of the intervals, it means that the type information and data card characteristic information do not match, and the SIM card Not for data cards.

Exemplarily, if the data card feature information includes a list of ICCIDs recorded with multiple data cards, the specific implementation of step S608 may be that the application framework searches the list included in the data card feature information for the ICCID of the SIM card that needs to be registered. , if the ICCID of the currently inserted SIM is found, it indicates that the type information matches the data card feature information, and the SIM card is a data card. If the ICCID of the SIM card that needs to be registered is not found in the list, it indicates that the type information and the data card feature information No match, the SIM card is not a data card.

In some embodiments, the type information read by the application framework may include the IMSI of the SIM card that needs to be registered. Correspondingly, the data card feature information may include one or more IMSI intervals, or may include multiple data records recorded A list of the card's IMSI. The method of judging whether the current SIM is a data card based on the IMSI is the same as the judging process based on the ICCID, and will not be repeated here.

In some embodiments, the application framework may further determine whether the SIM card is a data card based on the APN in the type information.

Exemplarily, the data card feature information may include a common access point name of the data card, such as cmiot. In step S608, the application framework compares the APN carried in the context request message with the APN included in the data card feature information, if the APN in the context request message is consistent with any APN included in the data card feature information, it indicates that the The SIM card is a data card. If the APN in the context request message is inconsistent with each APN included in the feature information of the data card, it means that the SIM card is not a data card.

Exemplarily, the feature information of the data card may also include APNs commonly used by ordinary cards (referring to SIMs that support voice services and data services), such as cmnet, cmwap, and the like. In step S608, the application framework compares the APN of the context request message with the APN of the data card feature information, if the APN of the context request message is consistent with any APN in the data card feature information, it means that the SIM card is not a data card, If the APN of the context request message is inconsistent with each APN in the feature information of the data card, it indicates that the SIM card is a data card.

In some optional embodiments, the application framework may further combine the above several types of information to determine whether the SIM card to be registered is a data card.

For example, the type information read by the application framework may include MSISDN and ICCID. After the comparison determines that both MSISDN and ICCID match the corresponding data card feature information, the application framework determines that the SIM card that needs to be registered is a data card. On the contrary, if at least one of the MSISDN and the ICCID does not match the characteristic information of the data card, the application framework determines that the SIM card to be registered is not a data card.

The advantage of judging whether the SIM card is a data card by synthesizing several types of information is that it can improve the accuracy of the judgment result and avoid misjudgment.

In some optional embodiments, the application framework may also determine whether the SIM card to be registered is a data card before step S602, that is, before the modem processor sends the voice-centric attachment request, and if it determines The SIM card that needs to be registered is a data card, then the application framework instructs the modem processor to send a data-centric attachment request, if it is judged that the SIM card that needs to be registered is not a data card, then the modem processor still sends a data card. Voice-centric attach request.

In some optional embodiments, the application framework may also execute step S609 based on the judgment result recorded in the internal memory. For the specific execution method, please refer to the relevant content in step S601.

The user setting of this field is configured as Data centric, that is, data-centric. After the modem processor receives this field, it can use this field to generate data-centric registration information.

Exemplarily, the application framework may also send indication information to the modem processor, and the modem processor generates data-centric registration information in response to the indication information.

Taking the 4G network as an example, in the voice domain preference and user settings fields sent by the application framework to the modem processor, the third binary bit representing the user settings is set to 1, indicating that the user settings are Data centric. Taking the 5G network as an example, in the user setting field sent by the application framework to the modem processor, the first binary bit is set to 1, indicating that the user is set to Data centric. After receiving the aforementioned fields, the modem processor can use the aforementioned fields to generate data-centric registration information.

S610, the application framework prompts the user that the SIM card only supports data services but not voice services.

In step S610 , the application framework may specifically prompt the user through the notification manager shown in FIG. 5 . For some optional prompting methods, refer to the embodiments corresponding to FIG. 3 and FIG. 4 , which will not be repeated here.

S615, the modem processor is disconnected from the target network.

In step S608, if the application framework determines that the SIM card to be registered is not a data card, the application framework may not send information to the modem processor. After the modem processor sends the registration failure information to the application framework, if the instruction of the application framework in step S609 is not received after a certain period of time, it can be considered that the SIM card to be registered is not a data card, and step S615 is automatically executed.

In some optional embodiments, if the modem processor receives an instruction to send data-centric registration information from the application framework after leaving the target network, the modem processor may continue to perform steps S611 to S614 .

In some optional embodiments, after leaving the target network, the modem processor may try to search for a non-target network, and initiate registration with the searched non-target network. The non-target network may specifically be a 2G network or a 3G network. If the modem processor successfully registers with the 2G or 3G network and resides on the 2G or 3G network, and receives the instruction of the application framework in step S609, the modem processor can leave the currently resident 2G or 3G network , and continue to execute steps S611 to S614.

If the modem processor fails to register in the 2G or 3G network, the modem processor can exit the cellular network, and the electronic device presents a state of no service as shown in FIG. 2b.

Optionally, the modem processor may also directly exit the cellular network after step S615.
