Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus and readable storage medium for providing local services. Background Technology

[0002] Fifth-generation (5G) wireless communication technology introduces non-public networks (NPNs). Unlike public networks (PNs), NPNs provide services to specific users or within a specific area, and may have time limitations. NPNs can meet the customized needs of vertical industries, such as in applications like the Industrial Internet and the Internet of Things (IoT).

[0003] Currently, NPNs can be used as hosting networks to provide potential users with access to local services offered by the NPN, such as access to the hosting network, the hosting network provider, or third-party service providers (including other network operators and third-party application providers). Providing local services to users can include providing data connectivity, as well as offering additional information or instructions to greatly enhance user experience or convenience. The use of hosting networks to provide local services also facilitates the promotion of service providers (such as physical businesses or specific building sites).

[0004] In related technologies, the way user equipment (UE) accesses local services through a managed network needs to be optimized. Summary of the Invention

[0086] The embodiments of this disclosure will now be further described in conjunction with the accompanying drawings and specific implementation details.

[0087] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure.

[0089] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.

[0090] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0091] like Figure 1As shown, the method for providing local services provided in this embodiment can be applied to a communication system 100 in a non-public network. This communication system 100 may include, but is not limited to, a non-public network (NPN) 101, user equipment (UE) 102, and a data network (DN) 103. The non-public network 101 includes network equipment 1011, an Access and Mobility Management Function (AMF) 1012, a Session Management Function (SMF) 1013, and a user plane function (UPF) 1014.

[0092] Network device 1011 can be an access network device (or access point). Access network devices refer to devices that provide network access functionality, such as radio access network (RAN) base stations. Specifically, network devices may include base station (BS) equipment, or base station equipment and radio resource management equipment used to control the base station equipment. This network device may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations. Network devices can be wearable devices or vehicle-mounted devices. Network devices can also be communication chips with communication modules.

[0093] For example, network equipment 1011 includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved nodeB, or home node B, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.

[0094] AMF1012 is responsible for user equipment 102's registration, connection, access authentication and authorization, mobility, and reachability management. SMF1013 is responsible for interacting with the separate data plane, managing session establishment, updates, and releases, maintaining protocol data unit (PDU) session state, and managing user equipment 102's internet protocol address (IP) allocation. UPF1014 responds to requests from SMF1013 and is responsible for performing network user plane processing such as GTP-U protocol encapsulation and decapsulation, packet routing and forwarding, packet inspection, and Quality of Service (QoS) flow mapping.

[0095] User equipment 102 is configured to support carrier aggregation and can be connected to multiple carrier units of network equipment 1011, including a primary carrier unit and one or more secondary carrier units.

[0096] The user equipment 102 shown above can be a terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication equipment, terminal agent, or user equipment, etc. This user equipment 102 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices 1011 of one or more communication systems, and to receive network services provided by the network devices 1011, including but not limited to the base station shown in the figure.

[0097] User equipment 102 may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, user equipment in a future 5G network, or user equipment in a future evolved public land mobile network (PLMN) network, etc.

[0098] DN103 can be a data network in a non-public network 101. Multiple servers can be deployed in DN103 to provide corresponding local service business data.

[0099] Non-public networks (NPNs) 101 are defined in Release 16 (Rel-16) of the 3GPP standard. Currently, for NPNs that can be used as hosting networks, their differences from those defined in Rel-16 and Rel-17 can be defined. Local services within the hosted network NPN can also be defined, specifying the differences between local services and regular services, and defining the applicable time and area of ​​local services according to the local service protocol.

[0100] Furthermore, the relevant agreements define the requirements for the discovery, selection, and access of the managed network, so that user equipment 102 can discover, select, or access local services of the managed network. It should be understood that the managed network involved in the embodiments of this disclosure is limited to NPN.

[0101] The local operator of the managed network can control access to restricted local operator services (RLOS), such as restricting unauthenticated user equipment 102 to access RLOS only, while authenticated user equipment 102 can also use RLOS in a restricted state. It should be understood that services provided through RLOS can also be used by authenticated user equipment 102 that is not in a restricted state through other methods.

[0102] In related technologies, when user equipment 102 accesses local services through a hosted network, it needs credentials provided by its home network. This means that user equipment 102 can only access local services through the hosted network if there is a connection or service agreement (such as a roaming agreement) between the home network and the hosted network. However, when user equipment 102 moves to a hosted network that has no connection or service agreement with its home network, authentication will fail, and user equipment 102 will enter a restricted state, unable to register with the hosted network or access local services.

[0103] It is evident that the way local services are provided in the relevant technologies needs to be optimized, and the problem of how to reuse RLOS in the Evolved Packet System (EPS) needs to be solved so that user equipment 102, such as user equipment 102 in a restricted state, can access local services provided by the managed network.

[0104] This disclosure provides a method for providing local services. Figure 2 This is a flowchart illustrating a method for providing a local service according to an exemplary embodiment, such as... Figure 2As shown, the method includes steps S201 to S208, specifically:

[0105] In step S201, network device 1011 sends a broadcast message, which includes a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0106] In step S202, user equipment 102 selects a managed network based on the broadcast message from network device 1011. The broadcast message includes a managed network service indication, which indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0107] In step S203, user equipment 102 sends a registration request to network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service instruction.

[0108] In step S204, network device 1011 receives the registration request from user equipment 102 and sends the registration request to access and mobility management function AMF 1012, wherein AMF 1012 supports managed network services; the registration request includes the device identifier of user equipment 102 and a managed network service indication.

[0109] In step S205, AMF1012 receives a registration request from user equipment 102 sent by the network device. The registration request includes the device identifier of user equipment 102 and a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0110] In step S206, AMF1012 sends a registration acceptance message to user equipment 102 through network device 1011.

[0111] In step S207, network device 1011 receives the registration acceptance message sent by AMF 1012 and sends a registration acceptance message to user equipment 102.

[0112] In step S208, user equipment 102 receives a registration acceptance message from access and mobility management function AMF 1012.

[0113] In some possible implementations, the non-public network (NTN) 101 can be deployed as a stand-alone non-public network (SNPN) or a public network integrated non-public network (PNI-NPN).

[0114] In some possible implementations, NTN101 acts as a hosting network, and network device 1011 of NTN101 carries a Hosting Network Service Indication in its broadcast messages. Carrying this Hosting Network Service Indication indicates that the hosting network can support user equipment 102 in accessing localized services without a hosting network authentication certificate, such as providing localized services to user equipment 102 in a restricted state.

[0115] In some possible implementations, the service network that user equipment 102 was connected to before connecting to the hosting network (the currently connected service network) is the home network. The home network can also discover the hosting network near the location of user equipment 102, providing a reference for user equipment 102.

[0116] In one example, the home network could be a Public Land Mobile Network (PLMN).

[0117] In one example, the home network may be a non-public network other than the NTN of this disclosure.

[0118] In some possible implementations, network device 1011 may function as a relay, such as forwarding the registration request of user equipment 102 to AMF 1012, or forwarding the registration accept message of AMF 1012 to user equipment 102.

[0119] In the method disclosed herein, network device 1011 of non-public network 101 can broadcast to user equipment 102 that it can provide managed network services. User equipment 102 learns from the broadcast message of network device 1011 that non-public network 101 can provide managed network services, and sends a registration request to network device 1011 according to the broadcast message. Network device 1011 can forward the registration request sent by user equipment 102 and forward the registration acceptance message of AMF 1012 of non-public network 101, thereby connecting AMF 1012 with user equipment 102, which in turn facilitates non-public network 101 to provide local services to user equipment 102, such as user equipment 102 in a restricted state.

[0120] This disclosure provides a method for providing local services, applied to network device 1011. Figure 3 This is a flowchart illustrating a method for providing a local service according to an exemplary embodiment, such as... Figure 3 As shown, the method includes step S301:

[0121] In step S301, network device 1011 sends a broadcast message, which includes a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0122] In some possible implementations, the non-public network NTN101 is a network within an enterprise or a specific building site. The network device 1011 of NTN101 can broadcast to indicate that it can act as a hosted network and support restricted user equipment 102 to access local services.

[0123] In one example, NTN101 is a network within an enterprise, providing local services to UEs within the enterprise.

[0124] In one example, NTN101 is a network set up in a venue (such as a concert hall, stadium, etc.) to provide local services to UEs within the venue.

[0125] In some possible implementations, broadcast messages can be air interface messages sent without encryption, such as system messages.

[0126] In the method disclosed herein, the network device 1011 of the non-public network 101 can inform the user device 102 that it can provide managed network services through broadcasting, so that the user device 102 can establish a connection with the non-public network 101 after receiving the broadcast message, which is beneficial for the non-public network to provide local services to the user device 102.

[0127] This disclosure provides a method for providing local services, applied to network device 1011. Figure 4 This is a flowchart illustrating a method for providing a local service according to an exemplary embodiment, such as... Figure 4 As shown, the method includes steps S401 to S403:

[0128] In step S401, network device 1011 sends a broadcast message, which includes a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0129] In step S402, network device 1011 receives the registration request from user equipment 102 and sends the registration request to access and mobility management function AMF 1012, wherein AMF 1012 supports managed network services; the registration request includes the device identifier of user equipment 102 and a managed network service indication.

[0130] In step S403, network device 1011 receives the registration acceptance message sent by AMF1012 and sends a registration acceptance message to user equipment 102.

[0131] In some possible implementations, network device 1011 and AMF 1012 are logically interconnected via an NG interface.

[0132] In some possible implementations, user equipment 102 is a user equipment in a limited state. The managed network of this disclosure embodiment can provide local services to user equipment 102 in a limited state.

[0133] In this embodiment of the disclosure, the network device 1011 of the non-public network 101 can broadcast to the user equipment 102 that it can provide managed network services. The network device 1011 can forward the registration request sent by the user equipment 102 and forward the registration acceptance message of the AMF 1012 of the non-public network 101, thereby enabling the AMF 1012 to connect with the user equipment 102, which in turn facilitates the non-public network 101 to provide local services to the user equipment 102.

[0134] This disclosure provides a method for providing local services, applied to a network device 1011, the method including steps S401' to S404':

[0135] In step S401', network device 1011 sends a broadcast message, which includes a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0136] In step S402', network device 1011 receives the registration request from user equipment 102 and determines that AMF1012 meets the preset conditions. The preset conditions are used to instruct AMF1012 to support managed network services.

[0137] Step S403': Send a registration request to the Access and Mobility Management Function (AMF) 1012, wherein the AMF 1012 supports managed network services; the registration request includes the device identifier of the user equipment 102 and a managed network service indication.

[0138] In step S404', network device 1011 receives the registration acceptance message sent by AMF1012 and sends a registration acceptance message to user equipment 102.

[0139] In some possible implementations, the AMF1012 that meets the preset conditions may carry a Hosting Network Service Indication. The network device 1011 selects the AMF1012 with the Hosting Network Service Indication and sends the registration request of the user equipment 102 to the selected AMF1012.

[0140] In this embodiment of the disclosure, network device 1011 may select AMF 1012 that supports managed network services in order to provide local services to user equipment 102 in a restricted state.

[0141] This disclosure provides a method for providing local services, applied to a network device 1011. The method includes steps S401 to S403, or steps S401' to S404', wherein:

[0142] The registration acceptance message includes a list of local services, which includes at least one local service that the hosted network allows the user's device to access.

[0143] In some possible implementations, the AMF1012 may carry a localized service list in the registration acceptance message, indicating the local services it can provide.

[0144] In some possible implementations, the local service list may not be included in the registration acceptance message and may be sent separately. For example, the AMF1012 sends both the registration acceptance message and the local service list.

[0145] In some possible implementations, user equipment 102 accesses local services in DN103 via a hosted network, where at least one server may be deployed.

[0146] In some possible implementations, the list of local services includes one of the following:

[0147] At least one data network name (DNN);

[0148] At least one fully qualified domain name (FQDN);

[0149] At least one IP address;

[0150] Among them, the DNN, FQDN, or IP address has a one-to-one correspondence with the local service.

[0151] In one example, the list of local services may include the Data Network Name (DNN) of each server in DN103. Each DNN can locate a server, and each server is used to provide a local service.

[0152] In one example, the list of local services may include the fully qualified domain names (FQDNs) of each server in DN103, each FQDN being able to locate a server, and each server being used to provide a local service.

[0153] In one example, the list of local services may include the IP addresses of the servers in DN103, with each IP address locating a server and each server providing a local service.

[0154] In one example, the list of local services may include the DNN of some servers, the FQDN of some servers, or the IP address of some servers.

[0155] In this embodiment of the disclosure, the server corresponding to DN103 can be determined by DNN, FQDN or IP address, which is beneficial for user equipment 102 to selectively access the local service corresponding to this server.

[0156] This disclosure provides a method for providing local services, applied to the Access and Mobility Management Function (AMF1012). Figure 5 This is a flowchart illustrating a method for providing a local service according to an exemplary embodiment, such as... Figure 5 As shown, the method includes steps S501 to S502:

[0157] In step S501, AMF1012 receives a registration request from user equipment 102 sent by network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0158] In step S502, AMF1012 sends a registration acceptance message to user equipment 102 through network device 1011.

[0159] In some possible implementations, the registration request of user equipment 102 can be forwarded to AMF 1012 via network device 1011; the registration acceptance message of AMF 1012 can be forwarded to user equipment 102 via network device 1011.

[0160] In some possible implementations, the registration acceptance message may or may not include a list of local services.

[0161] In some possible implementations, user equipment 102 is a user equipment in a limited state.

[0162] In some possible implementations, the following steps may also be included between step S501 and step S502:

[0163] S51. Authenticate and authorize user equipment 102.

[0164] In one example, AMF1012 can perform authentication and authorization of user equipment 102 by interacting with the Authentication Server Function (AUSF).

[0165] In this embodiment of the disclosure, network device 1011 can forward the registration request sent by user equipment 102 and forward the registration acceptance message of AMF 1012 of non-public network 101. AMF 1012 interacts with user equipment 102, which is beneficial for non-public network 101 to provide local services to user equipment 102.

[0166] This disclosure provides a method for providing local services, applied to AMF1012, the method including steps S501-S502, wherein...

[0167] The registration acceptance message includes a list of local services, which includes at least one local service that the hosted network allows the user's device to access.

[0168] In some possible implementations, the list of local services includes one of the following:

[0169] At least one data network name (DNN);

[0170] At least one fully qualified domain name (FQDN);

[0171] At least one IP address;

[0172] Among them, the DNN, FQDN, or IP address has a one-to-one correspondence with the local service.

[0173] In some possible implementations, the local service list may not be included in the registration acceptance message and may be sent separately. For example, the AMF1012 sends both the registration acceptance message and the local service list.

[0174] In this embodiment of the disclosure, the AMF1012 may carry a list of local services in the registration acceptance message it sends, so that the user equipment 102 can selectively access the local services it needs.

[0175] This disclosure provides a method for providing local services, applied to AMF1012. Figure 6 This is a flowchart illustrating a method for providing a local service according to an exemplary embodiment, such as... Figure 6 As shown, the method includes steps S601 to S603:

[0176] In step S601, AMF1012 receives a registration request from user equipment 102 sent by network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0177] In step S602, AMF1012 sends a registration acceptance message to user equipment 102 through network device 1011.

[0178] The registration acceptance message includes a list of local services, which includes at least one local service that the managed network supports user device access to.

[0179] Step S603: When a service request for the first local service is received from the user equipment 102, a session based on the first local service is established with the user equipment 102, wherein the first local service is in the local service list.

[0180] In some possible implementations, when user equipment 102 receives a list of local services, it can select the desired local service based on the list of local services.

[0181] In some possible implementations, the service request is a PDU session request, and the AMF1012 establishes a PDU session with the user equipment 102 based on the PDU session request of the user equipment 102.

[0182] In this embodiment of the disclosure, in the scenario where the registration and acceptance message carries a local service list, the user equipment 102 can selectively initiate a PDU session for the first local service based on the local service list. The AMF 1012 establishes a PDU session based on the request of the user equipment 102, thereby the managed network provides the first local service to the user equipment 102 in a restricted state.

[0183] This disclosure provides a method for providing local services, applied to AMF1012, the method including steps S501-S502 and step S52:

[0184] In step S501, AMF1012 receives a registration request from user equipment 102 sent by network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0185] Step S52, AMF1012 obtains the local service list.

[0186] In step S502, AMF1012 sends a registration acceptance message to user equipment 102 through network device 1011. The registration acceptance message includes a list of local services, which includes at least one local service that the managed network supports for user equipment access.

[0187] In some possible implementations, the AMF1012 may obtain a list of local services from the Policy Control function (PCF).

[0188] This disclosure provides a method for providing local services, applied to AMF1012. Figure 7 This is a flowchart illustrating a method for providing a local service according to an exemplary embodiment, such as... Figure 7 As shown, the method includes steps S701 to S703:

[0189] In step S701, AMF1012 receives a registration request from user equipment 102 sent by network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service indication. The managed network service indication indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0190] In step S702, AMF1012 sends a registration acceptance message to user equipment 102 through network device 1011.

[0191] The registration acceptance message does not include a list of local services.

[0192] Step S703: When a service request for the second local service is received from the user equipment, the service request for the second local service is sent to the session management function (SMF).

[0193] Step S704: Accept the SMF session establishment accept message or session establishment reject message.

[0194] Step S705: Send a session establishment accept message or a session establishment reject message to the user equipment.

[0195] In some possible implementations, in scenarios where the registration acceptance message does not include the local service list, user equipment 102 may initiate a PDU session request based on its own needs. AMF1012 forwards the user equipment 102's PDU session request to SMF1013, so that SMF1013 can determine whether a second local service is supported in the local service list based on the user equipment 102's request.

[0196] In one example, if a second local service is supported in the list of local services, SMF1013 can send a session establishment receive message so that the managed network can provide local services to user equipment 102.

[0197] In one example, if a second local service is not supported in the local service list, the SMF1013 can send a session establishment rejection message.

[0198] In some possible implementations, the SMF1013 is interconnected with the UPF1014 via the N4 interface, and the two can establish an N4 session.

[0199] In this embodiment of the disclosure, in a scenario where the registration acceptance message does not include the local service list, the user equipment 102 can initiate a PDU session for a second local service based on demand. The SMF 1013 determines whether to establish a PDU session based on the local service list. When the PDU session is successfully established, the managed network can provide the second local service to the user equipment 102 in a restricted state.

[0200] This disclosure provides a method for providing local services, applied to user equipment 102. Figure 8 This is a flowchart illustrating a method for providing a local service according to an exemplary embodiment, such as... Figure 8 As shown, the method includes step S801:

[0201] Step S801: Select a managed network based on the broadcast message from network device 1011; the broadcast message includes a managed network service indication, which indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0202] In some possible implementations, user equipment 102 may automatically select or manually select a managed network based on user operation, such as selecting a nearby NTN 101 with a managed network service indication.

[0203] In the method disclosed herein, user equipment 102 can learn from the broadcast message of network device 1011 that non-public network 101 can provide managed network services, and select non-public network 101 that can be used as a managed network according to the broadcast message, so as to facilitate the establishment of a connection with non-public network 101 and thus facilitate the receipt of local services provided by non-public network 101.

[0204] This disclosure provides a method for providing local services, applied to user equipment 102, the method including steps S801-S803:

[0205] Step S801: Select a managed network based on the broadcast message from network device 1011; the broadcast message includes a managed network service indication, which indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0206] Step S802: Send a registration request to network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service instruction.

[0207] Step S803: Receive the registration acceptance message from the Access and Mobility Management Function (AMF).

[0208] In some possible implementations, user equipment 102 uses its own equipment information, such as a device identifier and a managed network service instruction, to initiate a registration request to network equipment 1011.

[0209] In some possible implementations, user equipment 102 is a user equipment in a limited state.

[0210] In this embodiment of the disclosure, user equipment 102 learns from a broadcast message from network device 1011 that non-public network 101 can provide managed network services, and sends a registration request to network device 1011 according to the broadcast message. Network device 1011 can forward the registration request sent by user equipment 102 and forward the registration acceptance message of AMF 1012 of non-public network 101, thereby connecting AMF 1012 with user equipment 102, which in turn facilitates non-public network 101 to provide local services to user equipment 102.

[0211] This disclosure provides a method for providing local services, applied to user equipment 102, the method including steps S801' to S803:

[0212] Step S801': Select a managed network based on the pre-configuration message, which includes parameters for non-public network information.

[0213] Step S802: Send a registration request to network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service instruction.

[0214] Step S803: Receive the registration acceptance message from the Access and Mobility Management Function (AMF).

[0215] Alternatively, the method includes steps S801”~S803:

[0216] In step S801, a managed network is selected based on the pre-configuration message and the broadcast message from network device 1011. The pre-configuration message includes parameters of non-public network information, and the broadcast message includes a managed network service indication, which indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0217] Step S802: Send a registration request to network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service instruction.

[0218] Step S803: Receive the registration acceptance message from the Access and Mobility Management Function (AMF).

[0219] In some possible implementations, the parameters of non-public network information in the pre-configured message can be: the NTN's DNN, FQDN, or IP address.

[0220] In some possible implementations, the pre-configuration message is pre-configured for the user equipment by its home network.

[0221] In this embodiment of the disclosure, the user equipment may select an NTN that can serve as a managed network based on a pre-configuration message, or based on a pre-configuration message and a broadcast message.

[0222] This disclosure provides a method for providing local services, applied to user equipment 102, the method including steps S801 to S803, wherein:

[0223] The registration acceptance message includes a list of local services, which includes at least one local service that the hosted network allows the user's device to access.

[0224] In some possible implementations, the list of local services includes one of the following:

[0225] At least one data network name (DNN);

[0226] At least one fully qualified domain name (FQDN);

[0227] At least one IP address;

[0228] Among them, the DNN, FQDN, or IP address has a one-to-one correspondence with the local service.

[0229] In this embodiment of the disclosure, user equipment 102 can selectively access local services according to its own needs to improve the experience.

[0230] This disclosure provides a method for providing local services, applied to user equipment 102, the method including steps S801 to S804:

[0231] Step S801: Select a managed network based on the broadcast message from network device 1011; the broadcast message includes a managed network service indication, which indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0232] Step S802: Send a registration request to network device 1011. The registration request includes the device identifier of user equipment 102 and a managed network service instruction.

[0233] Step S803: Receive a registration acceptance message from the Access and Mobility Management Function (AMF), wherein the registration acceptance message includes a list of local services, and the list of local services includes at least one local service that the managed network supports the user equipment for access.

[0234] Step S804: Send the service request for the first local service in the local service list to the AMF.

[0235] In this embodiment of the disclosure, in the scenario where the registration and acceptance message carries a local service list, the user equipment 102 can selectively initiate a PDU session for the first local service based on the local service list. The AMF 1012 establishes a PDU session based on the request of the user equipment 102, thereby the managed network provides the first local service to the user equipment 102 in a restricted state.

[0236] This disclosure provides a method for providing local services, applied to user equipment 102, the method including steps S801-S803 and steps S805-S806:

[0237] Step S801: Select a managed network based on the broadcast message from network device 1011; the broadcast message includes a managed network service indication, which indicates that the non-public network corresponding to network device 1011 can provide managed network services to support user equipment 102 in accessing local services.

[0242] In this embodiment of the disclosure, in a scenario where the registration acceptance message does not include the local service list, the user equipment 102 can initiate a PDU session for a second local service based on demand. The SMF 1013 determines whether to establish a PDU session based on the local service list. When the PDU session is successfully established, the managed network can provide the second local service to the user equipment 102 in a restricted state.

[0243] The following two examples illustrate the methods of this disclosure:

[0244] In one example of this disclosure, in a scenario where the registration acceptance message includes a list of local services, the interaction between the non-public network 101 and the user equipment 102 can be found in [reference needed]. Figure 9 As shown. Figure 9 As shown, the method in this example may include the following steps:

[0245] S91, network device 1011 sends a broadcast message, which includes a managed network service instruction.

[0246] S92, User equipment 102 selects a managed network based on the broadcast message from network device 1011.

[0247] S93, User Equipment 102 sends a registration request to Network Equipment 1011. The registration request includes the User Equipment 102's device identifier (UE ID) and a managed network service indication.

[0248] S94, Network device 1011 sends a registration request to AMF1012.

[0249] S95 and AMF1012 receive registration requests and can authenticate and authorize user equipment 102.

[0250] S96 and AMF1012 decide to accept the registration request and send a registration acceptance message to network device 1011, which includes a list of local services.

[0251] S97, Network device 1011 sends a registration acceptance message to user device 102.

[0252] S98, User Equipment 102 accesses the first local service based on the PDU session of the first local service.

[0253] In another example of this disclosure, in a scenario where the registration acceptance message does not include a list of local services, the interaction between the non-public network 101 and the user equipment 102 can be found in [reference needed]. Figure 10 As shown. Figure 10 As shown, the method in this example may include the following steps:

[0259] S106, User equipment 102 sends a second local service PDU session request to SMF1013 through AMF1012.

[0260] S107 and SMF1013 determine whether to accept the session establishment.

[0261] S108. If SMF1013 sends a PDU session establishment acceptance message to user equipment 102, user equipment 102 accesses the second local service based on the PDU session of the second local service.

[0262] Among them, the Unified Data Management (UDM) function is responsible for the management of user identification, subscription data, authentication data, and user service network element registration management (such as the AMF and SMF that currently provide services to the terminal; when a user switches to the AMF they access, the UDM will also send a deregistration message to the old AMF, requesting the old AMF to delete the user's relevant information).

[0263] Based on the same concept as the above method embodiments, this disclosure also provides a communication device that can have the functions of the network device 1011 in the above method embodiments and is used to execute the steps performed by the network device 1011 provided in the above embodiments. This function can be implemented by hardware, or by software, or by hardware executing corresponding software.

[0267] When the communication device 1200 needs to send data, the processor 1202 performs baseband processing on the data to be sent and outputs a baseband signal to the radio frequency (RF) unit. The RF unit then performs RF processing on the baseband signal and transmits the RF signal as electromagnetic waves through an antenna. When data is sent to the communication device 1200, the RF unit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 1202. The processor 1202 converts the baseband signal back into data and processes the data.
