[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] In the related art, when the public land mobile network (PLMN) corresponding to the terminal device does not support the Tiantong satellite communication service, the process of opening the Tiantong satellite communication service for the terminal device is as follows: Figure 1 As shown, the following steps are included:

[0029] (1) Power on the terminal device;

[0030] (2) The terminal device sends a registration request message carrying the International Mobile Subscriber Identity (IMSI) to the core network Mobility Management Entity (MME);

[0031] (3) The MME queries the Home Subscriber Server (HSS) for authentication information;

[0032] (4) If the PLMN corresponding to the terminal device does not support satellite communication services, the core network HSS fails to query the subscription information based on the IMSI;

[0033] (5) The core network HSS notifies the MME that the authentication information acquisition failed;

[0034] (6) The core network MME sends a registration rejection message to the terminal device, and the registration rejection message carries a specific cause value.

[0035] As can be seen from the above process, if the PLMN corresponding to the terminal device does not support satellite communication services, the registration process initiated by the terminal device will fail. However, in the existing technology, regardless of whether the terminal device's PLMN supports satellite communication services, the MME will interact with the HSS and query the HSS for authentication information. Due to the limited air interface resources of Tiantong satellite, to avoid wasting resources, such invalid air interface messages should be reduced, and ineffective interactions within the core network should be minimized.

[0036] In order to solve the above problems, relevant solutions are provided in the embodiments of the present application, which are described in detail below.

[0037] According to an embodiment of the present application, a method embodiment of a satellite communication service registration method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] The method embodiments provided in the embodiments of the present application can be used in Figure 2 The satellite communication service registration system shown is executed. Figure 2As can be seen, the system includes: a terminal device, a mobility management function network element of a core network, wherein the terminal device is used to determine a first public land mobile network list, wherein the first public land mobile network list includes relevant information of each public land mobile network that supports satellite communication services; before the terminal device initiates an initial registration request for a satellite communication service, determining the public land mobile network corresponding to the initial registration request, and determining whether the public land mobile network corresponding to the initial registration request matches the public land mobile network in the first public land mobile network list; if the public land mobile network corresponding to the initial registration request matches the first public land mobile network list, sending the initial registration request to the mobility management function network element of the core network; the mobility management function network element is used to determine whether the public land mobile network corresponding to the initial registration request matches the public land mobile network in a second public land mobile network list stored in the mobility management function network element, and sending a registration rejection message to the terminal device after determining that there is no match, wherein the second public land mobile network list includes relevant information of each public land mobile network that supports satellite communication services.

[0039] In the above operating environment, the embodiment of the present application provides a satellite communication service registration method, such as Figure 3 As shown, the method includes the following steps:

[0040] Step S302: The terminal device determines a first public land mobile network list, where the first public land mobile network list includes relevant information of each public land mobile network supporting satellite communication services.

[0041] In the technical solution provided in step S302, the step of determining the first public land mobile network list by the terminal device includes: receiving a first update instruction sent by a network server, wherein the first update instruction is used to at least indicate relevant information of a newly added public land mobile network supporting satellite communication services; and updating the first public land mobile network list according to the first update instruction. The relevant information of the public land mobile network may include identification information of the public land mobile network.

[0042] As an optional implementation, the first public land mobile network list is stored in a non-volatile storage medium in a baseband of the terminal device.

[0043] Optionally, the initial first public land mobile network list can be written into the terminal in a factory preset manner, such as writing into the non-volatile memory (NV) in the terminal strap, so that the first public land mobile network list will take effect immediately after the terminal device is powered on. When a new PLMN supports the opening of the Tiantong service, the network server pushes the new PLMN to the terminal device, and the terminal device takes effect immediately after receiving the new PLMN list. The process of terminal device updating PLMN is as follows: Figure 4 As shown, the network server pushes the new PLMN list to the application processor (AP) of the terminal device through the data service, and the AP of the terminal device pushes the data to the terminal baseband transmission modem (Modulator-Demodulator, Modem) software through the assistant terminal messages (AT).

[0044] Step S304: before the terminal device initiates an initial registration request for a satellite communication service, determining a public land mobile network corresponding to the initial registration request, and determining whether the public land mobile network corresponding to the initial registration request matches a first public land mobile network list;

[0045] In the technical solution provided in step S304, the step of determining the public land mobile network corresponding to the initial registration request includes: when the terminal device includes a user identification card, determining the mobile country code and mobile network code corresponding to the user identification card corresponding to the initial registration request; and determining the public land mobile network corresponding to the initial registration request based on the mobile country code and mobile network code.

[0046] Specifically, such as Figure 5 As shown, when a user wishes to initiate a satellite communication registration process through a terminal device, the terminal device uses the Mobile Country Code (MCC) and Mobile Network Code (MNC) in the PLMN to determine whether the PLMN in the current subscriber identity card (IMSI) is in the first public land mobile network list before sending the initial registration request. If it is, the registration request is initiated normally. If not, the registration request is not initiated and the terminal device directly intercepts the registration process.

[0047] As an optional implementation manner, the steps of determining the public land mobile network corresponding to the initial registration request and determining whether the public land mobile network corresponding to the initial registration request matches the public land mobile networks in the first public land mobile network list include: when the terminal device includes multiple subscriber identification cards, determining the mobile country code and mobile network code corresponding to each subscriber identification card respectively, and determining the public land mobile network corresponding to each subscriber identification card based on the mobile country code and mobile network code corresponding to each subscriber identification card; determining whether the public land mobile network corresponding to each subscriber identification card matches the public land mobile networks in the first public land mobile network list, and when it is determined that the public land mobile network corresponding to at least one subscriber identification card matches, determining that the public land mobile network corresponding to the initial registration request matches the public land mobile networks in the first public land mobile network list.

[0048] In some embodiments of the present application, the satellite communication service registration method further includes: generating an initial registration request based on relevant information of the public land mobile network corresponding to the target user identification card and relevant information of the target user identification card, wherein the target user identification card is a user identification card whose corresponding public land mobile network matches the public land mobile network in the first public land mobile network list.

[0049] Specifically, some terminal devices may have multiple card slots to support users inserting multiple user identification cards, one or more of which may support the Tiantong satellite communication service. The terminal device can determine which user identification cards support the Tiantong satellite communication service based on the first public land mobile network list. In this way, when a user wishes to register for the Tiantong satellite communication service, the user identification card that supports the Tiantong satellite communication service is selected to generate and send an initial registration request. If Card 1 is Tiantong Card 46059, which supports the Tiantong service, and Card 2 is a competitor's card 46001, which does not support the Tiantong service, the Tiantong terminal baseband chip selects Card 1's IMSI to register for the Tiantong service instead of Card 2's IMSI.

[0050] In some embodiments of the present application, Figure 5 As shown, the method provided in the embodiment of the present application includes two processes: presetting and using the Tiantong PLMN list (that is, the first public land mobile network list), and updating the Tiantong PLMN list.

[0051] Specifically, from Figure 5 As can be seen from the figure, the process of presetting and using the Tiantong PLMN list includes the following steps:

[0052] The first step is to preset the data of the terminal device at the factory and write the Tiantong PLMN list into the baseband modem;

[0053] Step 2: After the terminal device is powered on, the Tiantong baseband modem reads the Tiantong PLMN list preset in NV;

[0054] Step 3: After the terminal device is powered on, the Tiantong baseband modem reads the IMSI;

[0055] Step 4: The modem extracts the PLMN (MCC+MNC) from the IMSI.

[0056] Step 5: The Modem determines whether the PLMN extracted from the IMSI is in the Tiantong PLMN list;

[0057] Step 6: If it is in the Tiantong PLMN list, the terminal device initiates the Tiantong registration process;

[0058] Step 7: If the PLMN is not in the Tiantong PLMN list, the terminal device will not initiate the Tiantong registration process.

[0059] The update process of Tiantong PLMN list includes the following steps:

[0060] The first step is that as services develop and more PLMNs support Tiantong services, the network server updates the list of PLMNs that support Tiantong;

[0061] In the second step, the network server pushes the updated Tiantong PLMN list to the terminal device AP side;

[0062] The third step is that the AP side of the terminal device pushes the Tiantong PLMN list to the baseband modem side of the terminal device through the AT message;

[0063] In the fourth step, the terminal device baseband modem writes the updated Tiantong PLMN list into the modem's NV.

[0064] Step S306: If the public land mobile network corresponding to the initial registration request matches a public land mobile network in the first public land mobile network list, sending the initial registration request to the mobility management function network element of the core network, wherein the mobility management function network element is configured to determine whether the public land mobile network corresponding to the initial registration request matches a public land mobile network in a second public land mobile network list stored in the mobility management function network element, and sending a registration rejection message to the terminal device after determining that there is no match, wherein the second public land mobile network list includes relevant information of each public land mobile network that supports satellite communication services.

[0065] In the technical solution provided in step S306, the second public land mobile network list is updated in the following manner: the mobility management function network element receives a second update instruction sent by the network server, wherein the second update instruction is used to at least indicate relevant information of a newly added public land mobile network supporting satellite communication services; and the second public land mobile network list is updated according to the second update instruction.

[0066] In some embodiments of the present application, the second public land mobile network list can be written into the MME of the core network in a preset manner, and the second public land mobile network list includes identification information of the PLMN that supports the Tiantong satellite service. The second public land mobile network list in the core network MME will take effect immediately after the MME is powered on. Subsequently, when the core network MME receives the initial registration request message sent by the baseband chip of the Tiantong terminal device, it adds judgment logic to extract the PLMN from the carried IMSI; if the PLMN of the IMSI is in the second public land mobile network list, it will be processed normally and the authentication process will be initiated; if the PLMN of the IMSI is not in the second public land mobile network list, the authentication process will not be initiated, and the core network MME will directly intercept the registration process and send a registration rejection message to the baseband chip of the terminal device.

[0067] A first public land mobile network list is determined by using a terminal device, wherein the first public land mobile network list includes relevant information of various public land mobile networks that support satellite communication services; before the terminal device initiates an initial registration request for the satellite communication service, the public land mobile network corresponding to the initial registration request is determined, and whether the public land mobile network corresponding to the initial registration request matches the first public land mobile network list; if the public land mobile network corresponding to the initial registration request matches a public land mobile network in the first public land mobile network list, the initial registration request is sent to a mobility management function network element of a core network, wherein the mobility management function network element is used to determine whether the public land mobile network corresponding to the initial registration request matches a second public land mobile network stored in the mobility management function network element. The method matches the public land mobile networks in the public land mobile network list, and sends a registration rejection message to the terminal device after determining that there is no match. The second public land mobile network list includes relevant information of each public land mobile network that supports satellite communication services. By setting a table containing relevant information of public land mobile networks that support satellite communication services in the terminal device and the mobility management function network element, the purpose of allowing the terminal device and the mobility management function network element to assist in determining whether the registration request initiated by the terminal device is passed is achieved, thereby achieving the technical effect of avoiding a large number of invalid registration requests from being sent to the home user server, and further solving the technical problem in the related art that the home user server determines whether the terminal device can activate the satellite communication service, resulting in excessive occupation of Tiantong satellite air interface resources.
