As shown in fig. 1, a method for providing a local service according to an embodiment of the present disclosure may be applied to a communication system 100 of a non-public Network, where the communication system 100 may include, but is not limited to, a non-public Network (NPN) 101, a User Equipment (UE) 102, and a Data Network (DN) 103. The non-public network 101 includes network devices 1011, access and mobility management functions (Access and Mobility Management Function, AMF) 1012, session management functions (Session Management Function, SMF) 1013, and user plane functions (user plane function, UPF) 1014.

The network device 1011 may be an access network device (or access network site). The access network device refers to a device that provides a network access function, such as a radio access network (radio access network, RAN) base station, etc. The network device may specifically include a Base Station (BS) device, or include a base station device, a radio resource management device for controlling the base station device, and the like. The network device may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, etc. The network device may be a wearable device or an in-vehicle device. The network device may also be a communication chip with a communication module.

For example, network devices 1011 include, but are not limited to: a next generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in LTE system, a radio network controller (radio network controller, RNC), a Node B (NB) in WCDMA system, a radio controller under CRAN system, a base station controller (basestation controller, BSC), a base transceiver station (base transceiver station, BTS) in GSM system or CDMA system, a home base station (e.g., home evolved nodeB, or home node B, HNB), a baseband unit (BBU), a transmission point (transmitting and receiving point, TRP), a transmission point (transmitting point, TP), a mobile switching center, or the like.

The AMF1012 is responsible for registration, connection, access authentication authorization, mobility, and reachability management of the user equipment 102. The SMF1013 is responsible for interacting with the separate data planes, managing session establishment, update and release and maintaining protocol data unit (protocol data unit, PDU) session state, and for address (internetprotocol address, IP) allocation management of the user equipment 102. The UPF1014 is responsible for completing the encapsulation and decapsulation of the GTP-U protocol on the user plane, packet routing and forwarding, packet inspection, quality of service (quality of service, qoS) flow mapping, and other network user plane processing in response to the request of the SMF 1013.

User equipment 102 is configured to support carrier aggregation, and user equipment 102 may be connected to multiple carrier units of network equipment 1011, including one primary carrier unit and one or more secondary carrier units.

The user equipment 102 shown above may be a terminal (terminal), an access terminal, a terminal unit, a terminal station, a Mobile Station (MS), a remote station, a remote terminal, a mobile terminal (mobile terminal), a wireless communication device, a terminal proxy, a user equipment, or the like. The user device 102 may be provided with wireless transceiver functionality capable of communicating (e.g., wirelessly communicating) with one or more network devices 1011 of one or more communication systems and receiving network services provided by the network devices 1011, where the network devices 1011 include, but are not limited to, the illustrated base stations.

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

DN103 can be a data network in non-public network 101 and multiple servers can be deployed in DN103 to provide traffic data for corresponding local services.

The non-public network 101 is defined in Release 16 (rel-16) of the third generation partnership project (3 GPP) standard. Currently, for NPNs that can be used as hosting networks (hosting networks), differences from NPNs defined in Rel-16 and Rel-17 can be defined. It is also possible to define local services in the managed network NPN and to indicate the distinction between local services and regular services, and to define the applicable time and applicable area of local services according to the local service protocol.

In addition, requirements for discovery, selection, and access of the hosted network are defined in the relevant protocols so that the user device 102 can discover, select, or access local services of the hosted network. It should be understood that the managed network to which embodiments of the present disclosure relate is limited to NPN.

The home operator of the managed network may control access to restricted home operator services (Restricted local operator services, RLOS), such as restricting access to RLOS only to unauthenticated user equipment 102, which may also be used by authenticated user equipment 102 in a restricted state. It should be appreciated that services provided by the RLOS may also be used by other methods for authenticated user equipment 102 that is not in a restricted state.

In the related art, when the user equipment 102 accesses the local service through the managed network, credentials provided by a home network (home network) to which the user equipment 102 is connected, that is, in a case where a connection or service protocol (such as a roaming protocol) exists between the home network and the managed network, the user equipment 102 may access the local service through the managed network. When the user equipment 102 moves under the coverage of the hosting network that has no connection/service agreement with the home network, authentication will fail, the user equipment 102 enters a restricted state, cannot register with the hosting network, and cannot access local services.

It can be seen that the manner in which the local service is provided in the related art needs to be optimized, and the problem of how to reuse RLOS in the evolved packet system (Evolved Packet System, EPS) needs to be solved, so that the user equipment 102, such as the user equipment 102 in a restricted state, can access the local service provided by the managed network.

An embodiment of the present disclosure provides a method for providing a local service, and fig. 2 is a flowchart illustrating a method for providing a local service according to an exemplary embodiment, as shown in fig. 2, where the method includes steps S201 to S208, and specifically:

in step S201, the network device 1011 transmits a broadcast message including a hosted network service instruction for instructing: the non-public network to which network device 1011 corresponds can provide hosted network services to support access by user device 102 to local services.

Step S202, the user equipment 102 selects a managed network according to the broadcast message of the network equipment 1011; the broadcast message includes a hosted network service indication, where the hosted network service indication is used to indicate: the non-public network to which network device 1011 corresponds can provide hosted network services to support access by user device 102 to local services.

In step S203, the user equipment 102 sends a registration request to the network equipment 1011, where the registration request includes the device identifier of the user equipment 102 and the hosted network service indication.

Step S204, the network device 1011 receives the registration request of the user equipment 102 and sends the registration request to the access and mobility management function AMF1012, wherein the AMF1012 supports the managed network service; the registration request includes a device identification of the user device 102 and a hosted network service indication.

Step S205, the AMF1012 receives the registration request of the user equipment 102 sent by the network equipment; the registration request includes a device identifier of the user device 102 and a hosted network service indication, where the hosted network service indication is used to indicate: the non-public network to which network device 1011 corresponds can provide hosted network services to support access by user device 102 to local services.

In step S206, the AMF1012 transmits a registration acceptance message to the user equipment 102 through the network equipment 1011.

In step S207, the network device 1011 receives the registration acceptance message transmitted by the AMF1012 and transmits the registration acceptance message to the user device 102.

In step S208, the user equipment 102 receives the registration accept message of the access and mobility management function AMF 1012.

In some possible embodiments, the non-Public Network (NTN) 101 may be deployed as a Stand-alone non-Public Network (SNPN), or as a non-Stand-alone non-Public Network (PNI-NPN).

In some possible implementations, NTN101 acts as a hosting network (NTN), and network device 1011 of NTN101 carries a hosted network service indication (Hosting Network Service Indication) in the sent broadcast message. When this hosted network service indication is carried, it indicates that the hosted network may support the user device 102 to access a local service without the hosted network authentication credentials (localized service), such as providing the local service for the user device 102 in a restricted state.

In some possible implementations, the serving network (currently connected serving network) to which the user equipment 102 is connected prior to connecting with the hosted network is a home network (home network). The home network may also discover a hosted network in the vicinity of where user device 102 is located, providing a reference to user device 102.

In an example, the home network may be a public land mobile network (Public Land Mobile Network, PLMN).

In an example, the home network may be other non-public networks other than NTN of embodiments of the present disclosure.

In some possible implementations, the network device 1011 may function as a relay, such as forwarding a registration request of the user device 102 to the AMF1012 (registration request), or forwarding a registration accept message of the AMF1012 to the user device 102 (egistration accept).

In the method of the present disclosure, the network device 1011 of the non-public network 101 can inform the user device 102 itself that the hosted network service can be provided by broadcasting. The user device 102 knows that the non-public network 101 can provide the hosted network service through the broadcast message of the network device 1011 and sends a registration request to the network device 1011 according to the broadcast message. The network device 1011 may forward the registration request sent by the user device 102 and forward the registration accept message of the AMF1012 of the non-public network 101, so that the AMF1012 is connected to the user device 102, thereby facilitating the non-public network 101 to provide local services for the user device 102, such as the user device 102 in a limited state.

The embodiment of the present disclosure provides a local service providing method applied to a network device 1011, and fig. 3 is a flowchart illustrating a local service providing method according to an exemplary embodiment, as shown in fig. 3, the method includes step S301:

In step S301, the network device 1011 sends a broadcast message including a hosted network service indication for indicating: the non-public network to which network device 1011 corresponds can provide hosted network services to support access by user device 102 to local services.

In some possible implementations, the non-public network NTN101 is a network within an enterprise or particular building site, and the network device 1011 of the NTN101 may indicate itself as a hosted network by broadcasting, supporting restricted state user devices 102 accessing local services.

In an example, NTN101 provides local services to intra-enterprise UEs for an intra-enterprise network.

In one example, NTN101 provides local services to UEs within a venue (e.g., concert hall, stadium, etc.) for setting up a network within the venue.

In some possible implementations, the broadcast message may be an air interface message, such as a system message, that is sent without encryption.

In the method of the present disclosure, the network device 1011 of the non-public network 101 can inform the user device 102 itself by broadcasting that the managed network service can be provided, 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 the local service for the user device 102.

The embodiment of the present disclosure provides a local service providing method applied to a network device 1011, and fig. 4 is a flowchart illustrating a local service providing method according to an exemplary embodiment, as shown in fig. 4, the method includes steps S401 to S403:

in step S401, the network device 1011 sends a broadcast message including a hosted network service instruction for indicating: the non-public network to which network device 1011 corresponds can provide hosted network services to support access by user device 102 to local services.

Step S402, the network device 1011 receives a registration request of the user equipment 102 and sends the registration request to the access and mobility management function AMF1012, wherein the AMF1012 supports the managed network service; the registration request includes a device identification of the user device 102 and an indication of the hosted network service.

In step S403, the network device 1011 receives the registration acceptance message transmitted by the AMF1012 and transmits the registration acceptance message to the user equipment 102.

In some possible implementations, the network device 1011 and the AMF1012 are logically interconnected through an NG interface.

In some possible implementations, the user equipment 102 is a user equipment in a limited state (limited state). The hosting network of embodiments of the present disclosure may provide local services for user devices 102 in a restricted state.

In the embodiment of the present disclosure, the network device 1011 of the non-public network 101 can inform the user device 102 that itself can provide the managed network service by broadcasting. The network device 1011 may forward the registration request sent by the user device 102 and forward the registration accept message of the AMF1012 of the non-public network 101, so that the AMF1012 is connected to the user device 102, thereby facilitating the non-public network 101 to provide local services for the user device 102.

In some possible implementations, the AMF1012 meeting the preset conditions may carry a hosted network service indication (Hosting Network Service Indication). The network device 1011 selects an AMF1012 with a hosted network service indication and sends a registration request of the user equipment 102 to the selected AMF1012.

In an embodiment of the present disclosure, the network device 1011 may select the AMF1012 supporting the hosted network service so as to be able to provide local services for the user device 102 in a restricted state.
