[0038] This embodiment provides a method for establishing a connection in a network architecture. Figure 2 is a flowchart of the method for establishing a connection according to an embodiment of this application. As shown in Figure 2, the process includes the following steps:

[0039] Step S202: Receive a first message sent by the target user; wherein the first message includes the target identifier of the target terrestrial network to which the target user belongs, and the satellite network supports providing target roaming services to users belonging to the target terrestrial network;

[0040] Step S204: Send the authentication request of the target user to the target terrestrial network according to the target identifier, so as to instruct the target terrestrial network to authenticate the target user;

[0041] Step S206: In response to the successful authentication of the target user and the receipt of the service request sent by the target user, a connection is established between the target user and the target terrestrial network.

[0042] Figure 3 is a schematic diagram of the interaction process for establishing a connection according to an embodiment of this application. As shown in Figure 3, the process includes the following steps:

[0043] Step S302: The satellite network receives a first message carrying a target identifier sent by the target user;

[0044] Step S304: The satellite network sends an authentication request for the target user to the target ground network based on the target identifier included in the first message;

[0045] Step S306: The target terrestrial network authenticates the target user;

[0046] Step S308: If the authentication is successful, the target ground network returns an authentication success message to the satellite network;

[0047] In step S310, the satellite network forwards the authentication pass message to the target user;

[0048] Step S312: When there is pending business activity, the target user requests to establish a business connection.

[0049] In step S314, in response to the successful establishment of the service connection, the target user provides service through the target terrestrial network.

[0050] In the above steps, the target user is a roaming user, which includes, but is not limited to: mobile terminal users, IoT terminal users, and users of other terminal devices that simultaneously support satellite network communication and terrestrial network communication. For example, the target user includes, but is not limited to: mobile terminal users who support satellite communication and belong to a terrestrial operator network; the target terrestrial network includes, but is not limited to: terrestrial operator networks; and the target identifier includes, but is not limited to: terrestrial operator PLMN (Public Land Mobile Network) identifiers, etc.

[0051] The entities that perform the above steps can be satellite networks, etc., but are not limited to these.

[0052] Through the above steps, a method for establishing service connections that integrates satellite and terrestrial networks is provided. The satellite network sends the authentication request of the target user that meets the target requirements to the target terrestrial network to which the target user belongs for roaming user authentication. If the authentication is successful, a service connection is established between the target user and the target terrestrial network. This solves the problems in related technologies where the lack of a satellite and terrestrial network integration solution means that service connections can only be established using satellite and terrestrial networks separately, resulting in limited network functions, inability to coordinate resources, difficulty in meeting information fusion needs, and limited application scenarios. This method achieves the effects of enhanced coverage, improved system efficiency, and enhanced user experience.

[0053] For example, the solution in this application will be described below with reference to specific embodiments:

[0054] Figure 4 is a flowchart of a method for establishing a connection according to an embodiment of this application. As shown in Figure 4, in the satellite-ground network converged communication system of this application, the satellite network and the ground operator network (i.e., the aforementioned target ground network) interact through an interconnection interface. The process includes the following steps:

[0055] Step S402: The satellite network core network and the terrestrial operator network sign a roaming service agreement.

[0056] In step S404, the access network in the satellite network broadcasts a system information block (SIB), which carries the identifier of the PLMN operator that has signed up for inter-network roaming services.

[0057] In step S406, when the inter-network roaming access condition is triggered, the terrestrial operator's mobile phone direct connection terminal user (i.e., the aforementioned target user, which is described here using a mobile phone as an example) sends an access request to the satellite network access network after reading the broadcast system message of the satellite network access network, and establishes a Radio Resource Control (RRC) connection with the satellite network access network.

[0058] In step S408, the mobile phone direct connection terminal user initiates the inter-network roaming registration and authentication process, and completes the establishment of the control plane connection with the home terrestrial operator's network.

[0059] In step S410, if the terrestrial operator network initiates a service request, a paging message is sent to the mobile phone directly connected terminal; if the terrestrial operator network does not initiate a service request, proceed to step S412.

[0060] In step S412, the mobile phone direct connection terminal sends a service access request message to the satellite network access network, and the satellite network access network forwards the message to the satellite network core network after receiving it.

[0061] In step S414, after receiving the service access request message, the satellite network core network initiates the PDU (Protocol Data Unit) session establishment process to complete the establishment of the user plane connection between the mobile phone direct connection terminal and the terrestrial operator network.

[0062] Step S416: The mobile phone directly connects to the terminal and performs business services with the network of the terrestrial operator to which it belongs.

[0063] In step S404 above, for example, the SIB includes a list of PLMNs (plmn-IdentityList) that the satellite network can provide services (e.g., roaming services provided in conjunction with terrestrial operator networks, or satellite communication services provided independently); or, the SIB includes a list of PLMN messages (plmn-IdentityInfoLis) that the satellite network can provide services; or, the SIB includes a list of PLMNs (plmn-IdentityList) that the satellite network can provide roaming services in conjunction with terrestrial operator networks; or, the SIB includes a list of PLMN messages that the satellite network can provide services; wherein, the PLMN list records the identifiers of the PLMNs (Public Land Mobile Network) that are allowed to access, and the PLMN message list records the PLMN identifier information of the terrestrial operator related to the inter-network roaming service.

[0064] In step S404 above, the access request message carries the location information of the mobile phone directly connected terminal user and the terminal capability information of the mobile phone directly connected terminal. The AMF (Access and Mobility Management Function) in the satellite network core network determines the TAC (Tracking Area Code) identification information of the satellite network corresponding to the location of the mobile phone directly connected terminal based on the location information of the mobile phone directly connected terminal user.

[0065] Step S408 above may include the following steps:

[0066] In step S4081, the mobile phone directly connected terminal user sends a registration request message to the satellite network. The satellite network core network identifies the mobile phone directly connected terminal as a subscribed roaming user and locates the home network;

[0067] In step S4082, the satellite network core network sends an authentication request to the core network of the terrestrial operator to which the mobile phone direct-connect terminal user belongs through the interconnection interface.

[0068] In step S4083, the terrestrial operator's core network initiates the authentication and authorization process for roaming users and the NAS (Network Access Server) security process. During this process, the satellite network core network also obtains the roaming user's registration and subscription information from the terrestrial operator's core network.

[0069] In step S4084, the satellite network core network sends an initial context establishment request to the access network, which carries a registration acceptance message for the roaming user;

[0070] In step S4085, the satellite network access network sends an initial context establishment response to the core network, which carries a registration completion message for the roaming user;

[0071] Step S4086: For voice SMS services, the mobile phone directly connected terminal also needs to complete the registration and authentication process of the home IMS.

[0072] In step S4082 above, the authentication request includes the identification information of the mobile phone directly connected terminal user and the TAC identification information of the mobile phone directly connected terminal user. When the terrestrial operator network receives a service session request from the satellite network core network to establish a first service execution between the terrestrial operator network and the mobile phone directly connected terminal, it determines whether the first service can be executed based on the TAC identification information.

[0073] The above steps propose a method for direct satellite connection of mobile phones to enable terrestrial network users to access satellite networks, which meets the current demand of terrestrial operators for users to achieve satellite communication without changing their SIM cards or phone numbers.

[0074] In one embodiment, before receiving a first message sent by the target user, the method further includes: signing up for a roaming service with a first terrestrial network, wherein the first terrestrial network includes the target terrestrial network.

[0075] In the above steps, signing a roaming service agreement with the first terrestrial network includes, but is not limited to: receiving a signing request from the first terrestrial network requesting to sign a roaming service agreement with the satellite network; signing a roaming service agreement with the first terrestrial network based on the signing request; or, sending an instruction message to the first terrestrial network instructing the first terrestrial network to send the signing request, and receiving the signing request from the first terrestrial network; and signing a roaming service agreement with the first terrestrial network based on the signing request.

[0076] In one embodiment, after signing up for roaming service with a first terrestrial network, the method further includes: broadcasting a broadcast message including a first identifier of the first terrestrial network, wherein the first identifier includes the target identifier.

[0077] In the above steps, exemplarily, the satellite core network included in the satellite network sends the first identifier to the satellite access network included in the satellite network to instruct the satellite access network to broadcast a broadcast message including the first identifier. The first identifier includes, but is not limited to, the PLMN identifier of the first terrestrial network.

[0078] In one embodiment, the satellite network and the first terrestrial network transmit data through an interconnection interface.

[0079] In one embodiment, sending the authentication request of the target user to the target terrestrial network based on the target identifier to instruct the target terrestrial network to authenticate the target user includes: determining whether a target condition for sending the authentication request of the target user is met by: determining whether the target user has subscribed to the target roaming service, and determining whether the communication capability of the target user's device meets a predetermined requirement; determining that the target condition is met in response to the target user having subscribed to the target roaming service and the communication capability of the target user's device meeting the predetermined requirement; determining that the target condition is not met in response to the target user not having subscribed to the target roaming service or the communication capability of the target user's device not meeting the predetermined requirement; and sending the authentication request of the target user to the target terrestrial network based on the target identifier in response to the target terrestrial network to instruct the target terrestrial network to authenticate the target user.

[0080] In the above steps, for example, determining whether the communication capability of the target user equipment meets the predetermined requirements includes, but is not limited to: determining whether the communication capability of the target user equipment meets the predetermined requirements based on the terminal capability information of the target user equipment included in the registration request message sent by the target user. The terminal capability information includes, but is not limited to: the terminal capability (ue-Category) category extended in the terminal capability (ue-Capability) message to indicate the communication capability of the mobile phone directly connected to the terminal (e.g., the terminal capability category in the related art, the terminal capability category to be added in the future), or the terminal capability information included in the information element newly added in the terminal capability (ue-Capability) message to indicate the communication capability of the mobile phone directly connected to the terminal.

[0081] Through the above steps, the satellite network can forward authentication requests sent by target user equipment that meets the predetermined communication requirements and has subscribed to the target roaming service only to the target terrestrial network. This reduces unnecessary data transmission and processing, improves the efficiency of network resource utilization, prevents unauthorized or non-compliant terminals from accessing the network, and enhances network security.

[0082] In one embodiment, the method further includes: the satellite network core network determining whether the communication capabilities of the target user equipment meet predetermined requirements based on the terminal capability information of the target user equipment included in the registration request message sent by the target user.

[0083] In one embodiment, the method further includes: the satellite network access network determining whether the communication capabilities of the target user equipment meet predetermined requirements based on the terminal capability information of the target user equipment included in the registration request message sent by the target user.

[0084] In one embodiment, determining whether the target user has subscribed to the target roaming service includes: determining a first list of users belonging to the target terrestrial network and who have subscribed to the target roaming service; determining that the target user has subscribed to the target roaming service in response to the first user list including the target user; and determining that the target user has not subscribed to the target roaming service in response to the first user list not including the target user.

[0085] In the above steps, for example, determining whether the target user has subscribed to the target roaming service includes: determining whether the target user is a user in the first user list based on the PLMN identifier of the terrestrial operator to which the target user belongs, obtained during the target user registration process; or, determining whether the target user is a user in the first user list based on the user equipment identifier that can be used to identify the PLMN identifier of the terrestrial operator to which the mobile direct connection terminal user belongs, obtained during the target user registration process.

[0086] In one embodiment, upon receiving the access request, the satellite network sends a request message to the target user requesting to obtain the PLMN identifier of the target terrestrial network to which the target user belongs, or requesting to obtain a user equipment identifier that can be used to identify the PLMN identifier of the terrestrial network to which the mobile phone direct connection terminal user belongs, and determines whether the target user is a user in the first user list based on the feedback message received from the target user.

[0087] In one embodiment, after determining whether the target condition for sending the authentication request to the target user is met, the method further includes: in response to the failure to meet the target condition, sending a feedback message to the target user to inform them that authentication cannot be performed for the target user.

[0088] In one embodiment, the first message includes messages sent during the process of the target user registering for the target roaming service. Establishing a connection between the target user and the target terrestrial network in response to the target user's successful authentication and receipt of a service request from the target user includes: determining that the target user has successfully registered for the target roaming service in response to the target user's successful authentication; and establishing a connection between the target user and the target terrestrial network in response to the target user's successful registration for the target roaming service and receipt of a service request from the target user.

[0089] In one embodiment, the first message includes a registration request for the target roaming service sent by the target user.

[0090] Through the above steps, the satellite network forwards the roaming service registration request sent by the target user that meets the target requirements to the target terrestrial network to which the target user belongs for roaming user registration, and establishes a service connection between the target user and the target terrestrial network. This solves the problems in related technologies that, due to the lack of a fusion solution between satellite and terrestrial networks, can only establish service connections using satellite and terrestrial networks separately, resulting in limited network functions, inability to coordinate resources uniformly, difficulty in meeting information fusion needs, and limited application scenarios. This achieves the effects of enhanced coverage, improved system efficiency, and enhanced user experience.

[0091] In one embodiment, the authentication request includes an authentication request and a security process processing request. Sending the authentication request of the target user to the target terrestrial network according to the target identifier to instruct the target terrestrial network to authenticate the target user includes: sending the authentication request and the security process processing request to the target terrestrial network according to the target identifier to instruct the target terrestrial network to perform authentication and security process processing operations on the target user; establishing a connection between the target user and the target terrestrial network in response to the target user passing authentication and completing the security process processing operations and receiving a service request sent by the target user includes: establishing a connection between the target user and the target terrestrial network in response to the target user passing the authentication and completing the security process processing operations and receiving a service request sent by the target user.

[0092] In the above steps, for example, the security process includes, but is not limited to, the NAS security process.

[0093] This embodiment also provides a method for establishing a connection in a network architecture, applied to a target user equipment. Figure 5 is a flowchart of the method for establishing a connection according to an embodiment of this application. As shown in Figure 5, the process includes the following steps:

[0094] Step S502: In response to receiving a second message including a target identifier, a first message is sent to the satellite network that sent the second message, wherein the target identifier is an identifier of the target terrestrial network to which the target user using the target user equipment belongs, and the satellite network supports providing target roaming services to users belonging to the target terrestrial network, and the first message includes the target identifier;

[0095] Step S504: In response to the satellite network receiving the target identifier indicating that the target user has successfully registered for the target roaming service and that there is a service to be executed, the satellite network sends a service request to the satellite network to instruct the satellite network to establish a connection between the target user and the target terrestrial network.

[0096] In the above steps, the second message includes, but is not limited to: a target broadcast message sent by the satellite network including the target identifier, or an instruction message sent by the satellite network during the registration of the target roaming service for the target user, instructing the target user to send the target identifier. The target broadcast message is used to inform the user that roaming services can be provided to users belonging to a first terrestrial core network, where the first terrestrial network is a terrestrial network (e.g., a terrestrial operator network) that has a roaming service contract with the satellite network.

[0097] The entities that perform the above steps can be mobile terminals, computer terminals, IoT terminals, or other terminal devices that simultaneously support satellite network communication and terrestrial network communication, but are not limited to these.

[0098] Through the above steps, a method is provided to establish service connections in a roaming manner based on a converged satellite network and terrestrial network. The target user equipment sends a target identifier to the satellite network, and when the satellite network successfully registers the target roaming service of the target terrestrial network for the target user equipment based on the target identifier, a service connection for the service to be executed is established with the target terrestrial network. This solves the problems in related technologies where the lack of a converged satellite network and terrestrial network solution means that service connections can only be established using satellite networks and terrestrial networks separately, resulting in limited network functions, inability to coordinate resources, difficulty in meeting information fusion needs, and limited application scenarios.
