[0046] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0048] In some embodiments, the network device may include at least one of an access network device and a core network device. The access network device is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation eNB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, a communication satellite, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0049] In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

[0050] In some embodiments, the core network device may be a device including a first network element, a second network element, etc., or may be a plurality of devices or a group of devices, respectively including all or part of the first network element, the second network element, etc. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0051] It should be noted that, in order to facilitate understanding of the technical solution, the following embodiments are described using a terminal in the form of a smart phone as an example.

[0052] With the development of terminal technology, terminals that can support satellite communication functions are gradually entering the market.

[0053] In some embodiments, the terminal can support both conventional communication services (e.g., services based on cellular communications) and satellite communications services. In this scenario, the system architecture set up inside the terminal usually adopts a dual-modem solution, in which one modem is dedicated to providing services for cellular services and the other modem is dedicated to providing services for satellite communications.

[0054] Based on this, how to flexibly and stably select a network between a cellular network and a satellite communication network during user use of the terminal is a problem that needs to be solved urgently.

[0055] It should be noted that, in order to facilitate understanding of the embodiments of the present disclosure, some terms used in the embodiments of the present disclosure are explained below to facilitate understanding by those skilled in the art.

[0056] A Subscriber Identity Module (SIM) card is a card that stores basic user information and network information, enabling a user's phone or other device to connect to a mobile network and make calls, send messages, or use data.

[0057] It should be noted that the two SIM cards in the terminal may belong to the same operator or different operators, and the present embodiment does not limit this. In addition, in actual applications, a terminal device may support more than two SIM cards, which may be determined according to actual usage requirements, and the present embodiment does not limit this.

[0058] For the convenience of description, in the embodiments of the present disclosure, two SIM cards installed in the terminal are described as a first SIM card and a second SIM card respectively.

[0059] PIN lock (Personal Identification Number) is a security measure used to protect SIM cards. SIM cards are an important part of mobile devices for storing personal information and identifying users. PIN lock is a password used to restrict access to SIM cards to ensure that only users with the correct PIN code can use the SIM card.

[0060] When the user inserts the SIM card into the device, the device will ask the user to enter the correct PIN code. If the user enters the wrong PIN code continuously, the SIM card will be locked and further verification will be required to reactivate. This is to prevent unauthorized access and protect the user's personal information.

[0061] The PIN code usually consists of 4 to 8 digits and is preset by the SIM card provider as a default value (usually "1234"). It is recommended that users change the default PIN code to a personal security password immediately after receiving the SIM card to increase the security of the SIM card.

[0062] Kernel GPIO device refers to the GPIO device in the operating system kernel. GPIO (General Purpose Input / Output) is a common digital interface used to control external devices and sensors in computer systems.

[0063] Figure 1 is a flow chart of a communication method according to an exemplary embodiment. Figure 1 As shown, the communication method includes the following steps.

[0064] In step S11, in response to switching from the first SIM card to the second SIM card, a status query is performed on the second SIM card to obtain a status query result, wherein the first SIM card or the second SIM card is a SIM card for processing satellite communication services.

[0065] In step S12, the network link corresponding to the second SIM card is accessed based on the status query result.

[0066] In step S13, first information is sent to the network device, where the first information is information for the terminal to communicate with the network device based on the network link corresponding to the second SIM card.

[0067] The communication method provided by the embodiment of the present disclosure performs a status query on the second SIM card before switching between the first SIM card and the second SIM card, and performs switching based on the status query result, which can avoid the inability to switch the SIM card or abnormal communication quality after switching due to abnormal status related to the second SIM card, thereby affecting subsequent communication based on the second SIM card network link. In addition, the system is not reset during the switching process, which realizes the dynamic switching of the SIM card and ensures the smoothness of the communication system.

[0068] In some embodiments, the switching scenario between the first SIM card and the second SIM card may include at least one of the following:

[0069] The first SIM card is a SIM card used for processing satellite communication services, and the second SIM card is a SIM card not used for processing satellite communication services;

[0070] The first SIM card is a SIM card for processing satellite communication services, and the second SIM card is a SIM card for processing satellite communication services;

[0071] The first SIM card is a SIM card not used for processing satellite communication services, and the second SIM card is a SIM card used for processing satellite communication services.

[0072] It is understandable that in some application scenarios, when both the first SIM card and the second SIM card are SIM cards not used for processing satellite communication services, part or all of the contents of the above embodiments are also applicable.

[0073] In some embodiments, the first SIM card and the second SIM card each correspond to an independent management system.

[0074] For example, taking the first SIM card as a SIM card for processing cellular services and the second SIM card as a SIM card for processing satellite communication services as an example,

[0075] The first SIM card can correspond to a cellular system, or a chip integrated with a cellular system for independent control; the second SIM card can correspond to a satellite communication system, or a chip integrated with a satellite communication system for independent control.

[0076] It should be noted that, for the convenience of description, in some of the following examples, the first SIM card mentioned can be understood as a SIM card not used for processing satellite services, for example, the first SIM card is a SIM card used for processing cellular services. The second SIM card mentioned can be understood as a SIM card used for processing satellite services. The details can be judged according to the specific embodiment description, and will not be repeated here one by one.

[0077] In some embodiments, the status query of the second SIIM card may be implemented through the system architecture layer.

[0078] Exemplarily, the underlying structure (relative to the underlying structure of the system architecture layer) reports the switching status and / or switching event of the SIM card to the system architecture layer. In response to the system architecture layer receiving the switching status and / or switching event of the SIM card, a status query instruction is sent to the underlying structure, which is executed by the corresponding underlying structure.

[0079] In some embodiments, "obtain", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, which can be interpreted as receiving from other subjects, but is not limited to this.

[0080] In some embodiments, terms such as "certain", "preset", "preset", "set", "indicated", "some", "any", and "first" can be interchangeable, and "specific A", "preset A", "preset A", "set A", "indicated A", "some A", "any A", and "first A" can be interpreted as A pre-defined in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., and can also be interpreted as specific A, some A, any A, or first A, etc., but is not limited to this.

[0081] The communication method involved in the embodiment of the present disclosure may include at least one of steps S11 to S13. For example, step S11 may be implemented as an independent embodiment, step S12 may be implemented as an independent embodiment, step S13 may be implemented as an independent embodiment, and step S11+step S12+step S13 may be implemented as an independent embodiment, but is not limited thereto.

[0082] In some embodiments, step S11 and step S12 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0083] In some embodiments, step S11 and step S13 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0084] In some embodiments, step S12 and step S13 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0085] Figure 2 is a flow chart showing a method for accessing a network link corresponding to a second SIM card according to an exemplary embodiment. Figure 2 As shown, the following steps are included.

[0086] In step S21, a first query result and a second query result of the second SIM card are obtained, wherein the first query result represents the general status of the second SIM card, and the second query result represents whether the second SIM card has a PIN code lock status.

[0087] In step S22, based on the first query result and the second query result, the network link corresponding to the second SIM card is accessed.

[0088] The communication method provided in the embodiment of the present disclosure can select a corresponding network access solution based on different query results by querying the general status and PIN code lock status corresponding to the second SIM card, thereby increasing the flexibility of network access after the SIM card is switched.

[0089] In some embodiments, the general status query includes querying at least one of the following items:

[0090] International Mobile User Identification Code (IMSI) query, Integrated Circuit Card Identification Code (ICCID) query, Mobile User International ISDN Number (MSISDN) query, SIM card status query, network registration status query, communication service status query, etc.

[0091] In some embodiments, IMSI query, ICCID query, and MSISDN query may be used to identify relevant identification information of a user or a SIM card in a mobile network.

[0092] For example, for IMSI query, user information can be identified in the mobile network, and for ICCID identification, it can be used to identify SIM card information in the network, etc.

[0093] In some embodiments, the query result of the SIM card status may include at least one of the following: the SIM card is in a normal state, the SIM card is in a locked state, and the SIM card is in arrears state. Used to determine the availability of the SIM card.

[0094] In some embodiments, the query result of the network registration status may include at least one of the following: a status such as registered and a network failure, which is used to determine whether the SIM card is successfully connected to the mobile network.

[0095] In some embodiments, the query result of the communication service status may include at least one of the following: whether there is a call, whether there is a text message, whether the data service is activated, etc. It is used to determine the activation status of the function status of the current SIM card.

[0096] It should be noted that the content of the SIM card universal status can be obtained by querying the relevant commands of the SIM card or through the query service of the mobile network operator. The specific query method may vary depending on the operator or device type. This is only an exemplary enumeration rather than an exhaustive one, and is not a specific limitation. Other related content is also included in the description of the universal status, and will not be repeated here.

[0097] In some embodiments, for different first query results and / or different second query results, a corresponding processing method is selected to access the network link corresponding to the second SIM card.

[0098] In some embodiments, "query", "detection", "monitoring", etc. can be used interchangeably.

[0099] The communication method involved in the embodiment of the present disclosure may include at least one of step S21 to step S22. For example, step S21 may be implemented as an independent embodiment, step S22 may be implemented as an independent embodiment, and step S21+step S22 may be implemented as independent embodiments, but are not limited thereto.

[0100] In some embodiments, step S21 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0101] In some embodiments, step S22 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0102] Figure 3 is a flow chart showing a method for accessing a network link corresponding to a second SIM card according to an exemplary embodiment. Figure 3 As shown, the following steps are included.

[0103] In step S31, a first query result and a second query result are determined.

[0104] In step S32, when the first query result is that the second SIM card is in a normal state and the second query result is that the second SIM card does not have a PIN code lock, the network link corresponding to the second SIM card is accessed.

[0105] The communication method provided by the embodiment of the present disclosure clarifies the network link access scheme when the first query result is normal and the second query result is that there is no PIN code lock, thereby avoiding the inability to access the network link corresponding to the second SIM card due to unclear access scheme in this scenario.

[0106] In some embodiments, the first query result is that the universal state of the second SIM card is normal, which can be understood as all query items or part of the items in the current universal state of the second SIM card meet the preset switching requirements.

[0107] For example, the preset switching item requirement is that the second SIM card cannot be in arrears. If the second SIM card is not in arrears (for example Figure 2 In the normal state described in the relevant embodiments, the identification meets the preset switching requirements, that is, some inspection items in the current general state of the second SIM card meet the preset switching requirements.

[0108] In some embodiments, the first query result is that the second SIM card universal status is abnormal, and the network link corresponding to the second SIM card is not connected.

[0109] In some embodiments, the first query result is that the second SIM card universal status is abnormal, the second query result is not obtained, and the network link corresponding to the second SIM card is not intervened.

[0110] It is understandable that if the first query result obtained before the second query result is obtained is that the second SIM card universal state is abnormal, omitting the step of obtaining the second query result can avoid waste of related resources.

[0111] The communication method involved in the embodiment of the present disclosure may include at least one of step S31 to step S32. For example, step S31 may be implemented as an independent embodiment, step S32 may be implemented as an independent embodiment, and step S31+step S32 may be implemented as independent embodiments, but are not limited thereto.

[0112] In some embodiments, step S31 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0113] In some embodiments, step S32 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0114] Figure 4 is a flow chart showing a method for accessing a network link corresponding to a second SIM card according to an exemplary embodiment. Figure 4 As shown, the following steps are included.

[0115] In step S41, the first query result and the second query result are determined.

[0116] In step S42, when the first query result is that the second SIM card is in a normal state and the second query result is that the second SIM card is PIN locked, PIN unlocking is performed.

[0117] In step S43, in response to completing the PIN code unlocking, the network link corresponding to the second SIM card is accessed.

[0118] The communication method provided by the embodiment of the present disclosure clarifies the network link access scheme when the first query result is normal and the second query result is that there is a PIN code lock, thereby avoiding the inability to access the network link corresponding to the second SIM card due to unclear access scheme in this scenario.

[0119] In some embodiments, when the second query result is that the second SIM card has a PIN code lock, unlocking the PIN code includes:

[0120] In response to obtaining the second query result that the second SIM card has a PIN code lock, obtaining an unlock signaling, where the unlock signaling is used to unlock the PIN code;

[0121] Perform PIN code unlocking based on unlock signaling, and feedback the unlocking result after completing PIN code unlocking.

[0122] In some embodiments, the unlock signaling may be an unlock PIN code corresponding to the PIN code lock.

[0123] The communication method involved in the embodiment of the present disclosure may include at least one of step S41 to step S13. For example, step S41 may be implemented as an independent embodiment, step S42 may be implemented as an independent embodiment, step S43 may be implemented as an independent embodiment, and step S41+step S42+step S43 may be implemented as independent embodiments, but are not limited thereto.

[0124] In some embodiments, step S41 and step S42 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0125] In some embodiments, step S41 and step S43 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0126] In some embodiments, step S42 and step S43 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0127] Figure 5 FIG. 1 is a flow chart showing a method for switching from a first SIM card to a second SIM card according to an exemplary embodiment. Figure 5 As shown, the following steps are included.

[0128] In step S51, the first SIM card is powered off, and the second SIM card is powered on.

[0129] In step S52, the second SIM card is loaded.
