As shown in fig. 1, fig. 1 shows that the embodiment of the present application provides a communication system, which includes: a first device 10, and a vertical industry control center 20 in communication with the first device 10. The first device 10 may be connected to the vertical industry control center 20 in a wired manner or a wireless manner, which is not limited in the embodiment of the present application.

In one possible implementation, as shown in fig. 1, the communication system may further include: an access network management device 30 and one or more access devices 40. Wherein access network management device 30 is configured to manage one or more access devices 40. It is to be understood that the one or more access devices 40 can provide a non-public network for the industry vertical's work area in which the industry vertical control center 20 is located. In addition, in another possible implementation manner, as shown in fig. 1, the communication system may further include: one or more terminals (e.g., terminal 501, terminal 502, and terminal 503). The one or more terminals are located within the work area of the industry vertical in which the industry vertical control center 20 is located.

For example, the work area of a vertical industry may be distributed over multiple areas. Each area may correspond to a non-public network, and different areas may be covered by the same non-public network, that is, a non-public network may provide network coverage for different areas. The non-public network only serves the equipment managed or owned by a vertical industry operator, and provides network communication services such as data connection and the like for the equipment; terminals in the public network of the communication operator do not access the non-public network. A non-public network within an area may be used to provide access services to terminals within the area. For example, the work areas of the industry verticals include area 01, area 02, and area 03. Wherein the non-public network 01 in the area 01 is used for providing access service for the terminal in the area 01. The non-public network 02 in the area 02 is used to provide access services to terminals in the area 02. The non-public network 03 in the area 03 is used to provide access services to terminals in the area 03. It should be understood that the industry vertical control center 20 may be shared by multiple zones if the industry vertical work area is comprised of multiple zones. Or each of the plurality of areas corresponds to one industry vertical control center 20, which is not limited in the embodiment of the present application.

In fig. 1, a plurality of terminals include a terminal 501, a terminal 502, and a terminal 503. It is to be understood that, in an actual process, the communication system shown in fig. 1 may further include three or more terminals, which is not limited in this embodiment of the present application.

The plurality of terminals in the embodiment of the present application may include a terminal in a mobile state. Or the plurality of terminals may comprise fixedly deployed terminals. Alternatively, the plurality of terminals may include terminals in a mobile state and terminals in a fixed deployment.

Wherein the vertical industry control center 20 is configured to place a demand for deploying the non-public network on the first appliance 10. Such as the coverage area of the non-public network, network access parameters of the non-public network, the validity period of the non-public network, etc. For example, the vertical industry control Center 20 may be a control Center of a factory (Operation Technology Center), a control Center of a port, or the like. The industry vertical control center 20 can either directly provide the demand for deploying the non-public network to the first appliance 10 or indirectly forward the demand for deploying the non-public network to the first appliance 10. The industry vertical control center 20 may be a device other than a non-public network, and may be understood to be an application server of an industry vertical operator.

The non-public network in the embodiment of the present application may also be referred to as: a private network or a private network.

The first device 10 is configured to store environment information of a corresponding industry vertical, communication network deployment information of an area corresponding to the industry vertical, communication capability of a terminal, a group relationship, a deployment location of the terminal, and the like. Further, the first device 10 may determine that a non-public network needs to be opened. For example, the first device 10 may send the first configuration message to the access network management device 30 according to a requirement of deploying a non-public network set forth by the vertical industry control center 20. The first configuration message includes: network access parameters of the non-public network and a coverage area of the non-public network, so that the access network management device 30 instructs the access device 40 managed by the access network management device to provide the non-public network for one or more terminals to access the non-public network.

It should be understood that the first device 10 may be deployed in a core network. Access network management device 30 and access device 40 may be deployed in an access network. That is, after the demand for deploying the non-public network is provided by the vertical industry control center 20, the core network and the access network interactively process the demand for deploying the non-public network, so as to complete the deployment of the non-public network.

For example, the communication system shown in fig. 1 may be applied to the current 5G network architecture and other network architectures appearing in the future, and the embodiment of the present application is not particularly limited thereto.

The terminal communicates with the AMF network element through a Next generation network (N1) interface (N1 for short). The access equipment communicates with the AMF network element through an N2 interface (abbreviated as N2). The access equipment communicates with the UPF network element through an N3 interface (abbreviated as N3). The UPF network elements communicate with the DN over an N6 interface (abbreviated N6).

The PCF network element is communicated with the UDR network element, and the BSF network element is communicated with the PCF network element and the SMF network element. And the AMF network element communicates with the NVAF network element through a first interface. The AMF network elements communicate with each other through an N14 interface. Illustratively, the first interface may be an Nx interface.

Fig. 3 shows a service interface-based architecture in a non-roaming 5G network architecture, which differs from fig. 3 in that the control plane network element in the 5GC in fig. 3 can also interact with the service interface. For example, the AMF network element, the AUSF network element, the SMF network element, the UDM network element, the UDR network element, the NRF network element, the NEF network element, the NSSF network element, or the PCF network element use a service interface for interaction. For example, the service interface provided by the AMF network element to the outside may be Namf. The service interface externally provided by the SMF network element may be Nsmf.

For convenience of description, in the following embodiments of the present application, an LSMF network element, an AMF network element, an UPF network element, and an SMF network element are respectively referred to as LSMF, AMF, UPF, and SMF for short. It can be understood that the LSMF described later in this embodiment may be replaced by a user group management network element, the AMF may be replaced by a mobility management network element, the UPF may be replaced by a user plane network element, and the SMF may be replaced by a session management network element.

The NRF stores information of deployed Network Function (NF) components, such as identifiers and Network addresses of the NF components, identifiers of supported Network slices, and the like, and provides services such as registration and discovery of the NF components to other NFs.

In the access network part of next generation communication networks, in order to support flexible deployment of different service requirements and AN functions, the functions (e.g. access devices) within the access network may be decoupled into one or more Distributed Units (DUs) and one or more Central Units (CUs), as shown in fig. 4. The actual deployment mode of the CU and the DU is flexible. For example, the CU parts of a plurality of base stations are integrated together to form a larger functional network element. The access device may be implemented by one node, or may be implemented by a plurality of nodes, where the access device is configured to implement functions of Protocol layers such as Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Medium Access Control (MAC). For example, the CU and the DU may be divided according to protocol layers of the wireless network, for example, functions of a packet data convergence layer protocol layer and above protocol layers are disposed in the CU, protocol layers below the PDCP, and functions including RLC and MAC layers and the like are disposed in the DU. The first interface that exists between a CU and a DU may be referred to as the F1 interface.

This kind of protocol layer division is only an example, and it is also possible to divide at other protocol layers, for example, at the RLC layer, the functions of the RLC layer and the above protocol layers are set in the CU, and the functions of the protocol layers below the RLC layer are set in the DU; alternatively, the functions are divided into some protocol layers, for example, a part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are provided in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are provided in the DU. In addition, the processing time may be divided in other manners, for example, by time delay, a function that needs to satisfy the time delay requirement for processing is provided in the DU, and a function that does not need to satisfy the time delay requirement is provided in the CU.

In addition, please refer to fig. 4, the Control Plane (CP) and the user Plane (user Plane, UP) of the CU may be separated and divided into different network elements, which are respectively a Control Plane CU (CU-CP, abbreviated as CU-C) network element and a user Plane CU (CU-UP, abbreviated as CU-U) network element. With the separation of the control plane and the user plane of a CU, the interface between CU-C and DU can be called: F1-C. The interface between a CU-U and a DU may be referred to as: F1-U.

Wherein CU-C supports the functions and services of the control plane PDCP/RRC protocol control plane portion, as well as control of the DUs and CU-Us. The CU-U supports the user plane functions of a Packet Data Convergence Protocol (PDCP) Protocol and a Service Data Adaptation Protocol (SDAP) Protocol; the DUs implement the functionality of the RLC/MAC/PHY protocol.

As shown in fig. 4, the CU-U is connected to the user plane (NG-U) of the core network. The CU-C is connected with the control plane (NG-C) of the core network.

In the above network architecture, data generated by a CU may be transmitted to a terminal through a DU, or data generated by a terminal may be transmitted to a CU through a DU. The DU may not parse the data and directly encapsulate the data through a protocol layer and transmit the encapsulated data to the terminal or CU. For example, signaling of the RRC or PDCP Layer is finally processed into data of a Physical Layer (PHY) to be transmitted to the terminal, or converted from received data of the PHY Layer.

In the above embodiment, the CU serves as an access network device in the RAN, and in addition, the CU may also be divided into access network devices in the CN, which is not limited herein.

The apparatus in the following embodiments of the present application may be located in a terminal or a radio access network device according to the implemented functions. When the above structure of CU-DU is adopted, the access network device may be a CU node, or a DU node, or a RAN device including the functions of the CU node and the DU node.

In the prior art, a vertical industry operator can build a non-public network in a working area of the vertical industry, so that the self-built non-public network provides network coverage for the working area of the vertical industry. The self-built non-public network not only causes the increase of the network construction cost and the later maintenance cost. The self-established non-public network may also reduce the access efficiency of the terminal. Therefore, the embodiment of the application acquires the first request message of the vertical industry control center through the first device, and opens the non-public network for the working area of the vertical industry by the operator of the public network where the working area of the vertical industry is located based on the first request message. This avoids the cost of separately opening a non-public network for the work area of the industry vertical. In addition, by configuring network access parameters, the terminal can conveniently access the non-public network of the working area of the vertical industry in which the terminal is positioned, and the complexity of terminal access is reduced.

The steps executed by the first device in the method for configuring a radio bearer according to the present application may also be executed by a chip applied to the first device. The steps performed by the access network management device may also be performed by a chip applied to the access network management device, the steps performed by the access device in a method for configuring a radio bearer may also be performed by a chip applied to the access device, and the steps performed by the terminal in a method for configuring a radio bearer may also be performed by a chip applied to the terminal. The following embodiments exemplify a configuration method of a radio bearer performed by a first device, an access network management device, an access device, or a terminal. For the implementation method that the apparatus is a chip in the first device, a chip in the access network management device, or a chip in the access device or the terminal, reference may be made to specific descriptions of the apparatus for the first device, the access network management device, the access device, or the terminal, and a description thereof will not be repeated.

As shown in fig. 5, an embodiment of the present application provides a network access method, where the method includes:

step 101, a first device receives a first request message from a vertical industry control center. Wherein the first request message includes: requesting a coverage area of the non-public network to manage and network access parameters of the non-public network. The network access parameters of the non-public network are used for the terminal to access the non-public network.

In this embodiment, the network access parameter of the non-public network may be an identifier (non-public network identity) of the non-public network.

The coverage area of the non-public network can be a working area of a vertical industry in which a vertical industry control center is located. The coverage area of the non-public network may include a plurality of areas. It should be understood that the industry vertical control center may request that a non-public network be established for one or more areas, or update an established non-public network for one or more areas. Illustratively, the coverage area of the non-public network is an area identified using geographic coordinates.

In an optional implementation manner, before step 101, the method provided in the embodiment of the present application may further include: 100-1, a vertical industry control center determines a non-public network that manages a work area of a vertical industry. 100-2, the vertical industry control center sends a first request message to a first device. For example, a industry vertical control center determines a non-public network that manages a work area of a industry vertical based on the needs of industry vertical operators to deploy the network in the work area of the industry vertical.

The non-public network requested to be managed in the embodiment of the application can be newly established for the request. That is, if the non-public network is not established or opened in the working area of the vertical industry, the vertical industry control center may request the first device to establish the non-public network through the first request message. For example, the first request message is specifically for requesting establishment of a non-public network in a work area of a vertical industry.

The non-public network requesting management in the embodiment of the application may be a request for updating the established non-public network. That is, if the non-public network is opened in the working area of the vertical industry, and if the relevant configuration (for example, the coverage area or the effective time period) of the non-public network needs to be changed subsequently, the vertical industry control center may request the first device to update the non-public network through the first request message. For example, the range of the non-public network coverage is updated, or the effective time period of the non-public network coverage is updated. For example, the coverage area of the non-public network opened in the working area of the vertical industry is R, and if the control center of the vertical industry determines that the coverage area of the non-public network is to be expanded, the first request message may carry the updated coverage area of the non-public network.

It should be understood that the first device, the access network management device, and the access device are devices in a common network operator in which the work area of the industry vertical is located. For example, the Public network may be a Public Land Mobile Network (PLMN). The following embodiments take the public network operator as the PLMN network operator as an example.

In the embodiment of the present application, before step 100-1, a vertical industry operator of a vertical industry control center and a PLMN network operator have signed a service cooperation agreement.

Illustratively, the business cooperation agreement may include the following: non-public networks may be provided by PLMN network operators for industry vertical operators. Through the cooperation agreement, the PLMN network operator can determine the service authority of the vertical industry operator, the rules of charging, etc.

Because the user data management network element can provide the authentication of terminal access and information such as security parameters in a public network provided by a PLMN network operator or a non-public network required by a vertical industry operator. Namely, the vertical industry operator and the PLMN network operator correspond to a user data management network element respectively. And the user data management network element corresponding to the vertical industry operator is used for storing the subscription data, the authentication information and the like of the vertical industry terminal. And the user data management network element corresponding to the PLMN network operator is used for storing the subscription data, the authentication information and the like of the terminal in the PLMN network operator.

In addition, the service cooperation protocol may further include: the user data management network element of the vertical industry operator is managed by the vertical industry control center, and the user data management network element of the PLMN network operator is managed by the PLMN network operator. Other network functions such as an AMF network element, an SMF network element, a PCF network element, a UPF network element, etc. are managed by a PLMN network operator, and these network functions can be set individually by the PLMN network operator for the vertical industry operator, so that management and network services for the vertical industry terminal can be isolated from other terminals.

Step 102, the first device sends a first configuration message to the access network management device. The first configuration message includes: network access parameters of the non-public network and a coverage area of the non-public network. The access network management device is for managing access devices providing non-public networks.

It should be understood that the access device may be used to provide not only public networks, but also non-public networks.

Step 103, the access network management device receives a first configuration message from the first device.

And step 104, the access network management device sends the network access parameters of the non-public network to the access device providing the non-public network according to the coverage area of the non-public network.

It should be appreciated that the access network management device in step 104 finds the deployed access device for providing the public network in the coverage area of the non-public network and sends the network access parameters of the non-public network to the access device for providing the public network, which facilitates providing the non-public network using the access device for providing the public network.

And 105, the access device receives the network access parameter of the non-public network from the access network management device, wherein the network access parameter of the non-public network is used for the terminal to access the non-public network.

Step 106, the access device sends a broadcast message, wherein the broadcast message includes network access parameters of the non-public network.

It should be noted that if the access device determines to newly establish the non-public network, a broadcast message including network access parameters of the non-public network is sent in the coverage area of the non-public network requested by the industry vertical control center. If the access equipment determines to update the coverage area of the non-public network, the access equipment sends a broadcast message including network access parameters of the non-public network in the coverage area of the non-public network requested to be updated by the vertical industry control center. For example, if the coverage area of the non-public network established before the update is a, the access device sends a broadcast message including network access parameters of the non-public network within the coverage area a. And if the coverage area of the non-public network is B after updating, the access equipment sends a broadcast message comprising the network access parameters of the non-public network in the coverage area B.

Illustratively, through steps 101-106, the same public network operator may provide non-public networks for multiple areas. Of course, non-public networks covered by different areas may also be provided by different public network operators. For example, the non-public network of area 1 is provided by public network operator 1. The non-public network of area 2 is provided by a public network operator 2.

It should be noted that, if different areas cover different non-public networks, the network access parameters of the non-public network corresponding to each area may be different. In this way, by setting the network access parameters for different non-public networks covered by different areas respectively, independent setting and network access processing are not required according to different PLMN networks, thereby reducing the complexity of the terminal.

It should be noted that, in the embodiment of the present application, a terminal in a vertical industry may have an identifier of a user assigned to the terminal by a vertical industry operator, and a network access parameter of a non-public network. Therefore, when the access device sends the broadcast message, the terminal can access the corresponding non-public network according to the user identification distributed to the terminal by the vertical industry operator and the network access parameter of the non-public network carried in the broadcast message. Specifically, the network access parameter of the non-public network stored in the terminal is consistent with or has a mapping relationship with the network access parameter of the non-public network carried in the broadcast message, and the terminal accesses the corresponding non-public network according to the network access parameter of the non-public network carried in the broadcast message.

As shown in fig. 6, the same public network operator may provide non-public networks for multiple areas.

In a possible embodiment, with reference to fig. 6 and as shown in fig. 7, the method provided in the embodiment of the present application further includes:

step 107, the vertical industry control center sends any one or more of the following information to the first device: the system comprises a time indication of a non-public network, information of a terminal accessed to the non-public network, information of a user data management network element corresponding to the terminal and an identifier of a vertical industry control center, wherein the time indication is used for indicating an effective time period of the non-public network.

The information of the terminal accessing the non-public network is used for determining the terminal accessing the non-public network. For example, the information of the terminal accessing the non-public network may be a number segment of the vertical industry terminal user, that is, a user identifier accessing the non-public network. The user data management network element may be any one of a Unified Data Management (UDM) network element, a User Data Repository (UDR) network element, and a user home server (HSS) network element.

It should be understood that the information sent by the vertical business control center to the first device in step 107 may be sent to the first device alone, or may be sent to the first device by being carried in the above-mentioned first request message, which is not limited in this embodiment of the application. The vertical industry control center provides the time indication so that the core network and the access network can determine the time period for providing the non-public network conveniently, namely the access network can determine the network access parameters broadcast in the effective time period of the time indication so that the terminal can access the non-public network conveniently.

Illustratively, the time indication may be a start time and a duration period. For example, if the starting time is a and the duration period is L, the valid period is a + L. Or as yet another example, the time indication may be a start time and an end time. The validity period is the period between the start time and the end time.

The valid time period indicated by the time indication may be a continuous time period or a discontinuous time period. For example, the time indication indicates a valid time period of 08.00-10.00. For example, the time indication may indicate a valid time period of 08.00-10.00, 11.00-12.00, etc.

Step 108, the first device receives any one or more of the following information from the industry vertical control center: the system comprises a time indication of a non-public network, information of a terminal accessed to the non-public network, information of a user data management network element corresponding to the terminal and an identifier of a vertical industry control center, wherein the time indication is used for indicating an effective time period of the non-public network.

Illustratively, the information of the terminal accessing the non-public network is used to determine the terminal accessing the non-public network. That is, the information of the terminal accessing the non-public network may be the identifier of the user allocated to the terminal by the vertical industry operator. It can also be understood that: identification of the terminal used in the industry vertical. For example, the user's identity may be a user Permanent Identifier (SUPI), or a user hidden Identifier (SUCI) or a telephone number.

For example, the information of the terminal accessing the non-public network may be: A00100001-A00109999, and the network access parameter is A001.

For example, the information of the user data management network element may be an identification and an address of the user data management network element.

Step 109, the first device sends a time indication to the access network management device.

It should be understood that, in step 109, the first device may send the time indication to the access network management device separately, or the time indication may be sent to the access network management device by the first device in a first configuration message, so that the access network management device obtains the time indication from the first configuration message.

Step 110, the access network management device receives an indication of time from the non-public network of the first device.

And step 111, the access network management device sends the time indication to the access device.

Accordingly, step 106 may be specifically implemented by: and the access equipment transmits the broadcast message in the valid time period. It should be understood that, if the access device sends the broadcast message in the valid time period, the terminal may access the non-public network according to the network access parameters carried in the broadcast message in the valid time period. By providing the time indication, the access device can provide a non-public network for the working area of the industry vertical in the effective time period so as to save network resources.

It should be noted that, for the newly established non-public network, the access device transmits a broadcast message including the network access parameters of the non-public network within the valid time period C determined by the time indication. For the updated non-public network, if the valid time period of the opened non-public network is a, if the vertical industry control center determines that the valid time period of the opened non-public network needs to be updated, the vertical industry control center may further send an updated time indication of the non-public network to the first device. This facilitates the first device informing the access device via the access network management device to adjust the updated time indication for the non-public network. For example, the access device adjusts the validity period of the non-public network from validity period C to validity period B.

In a possible embodiment, with reference to fig. 7, as shown in fig. 8, the method provided in the embodiment of the present application further includes:

step 112, the first device sends a registration request to the network storage function, so that the network storage function receives the registration request. Wherein the registration request includes: the user data manages information of network elements and information of terminals accessing the non-public network.

It should be appreciated that by executing step 112, the network element (AUSF) performing terminal authentication can subsequently request the UDM corresponding to the terminal of the industry vertical from the network storage function when the terminal of the industry vertical accesses the non-public network.

Step 113, the first device receives a registration completion message from the network storage function. The registration completion message is used to indicate that authentication of the user data management network element and the terminal accessing the non-public network has been completed.

Specifically, the network storage function may store, in the network storage function, a mapping relationship between information of the user data management network element and information of the terminal accessing the non-public network, when receiving the registration request. Therefore, in the process that the terminal is accessed into the non-public network, the network storage function can send the information of the user data management network element corresponding to the information of the terminal accessed into the non-public network to the authentication server function network element according to the information of the terminal accessed into the non-public network from the authentication server function network element and the identification of the type of the user data management network element.

In one possible implementation manner, step 102 in the embodiment of the present application may be implemented by: and the first equipment determines that the vertical industry control center has the authority of managing the non-public network according to the first request message, and the first equipment sends a first configuration message to access network management equipment.

Specifically, the first device performs an authorization check on the first request message, and determines whether to permit the first request message. For example, the first device determines whether the vertical industry operator has a right to open a non-public network, and sends the first configuration message if the vertical industry operator has the right to open the non-public network. And if the vertical industry operator does not have the authority of opening the non-public network, sending a request for refusing the vertical industry control center to manage the non-public network.

The first device determining that the vertical industry control center has authority to manage the non-public network may be implemented by: on one hand, a vertical industry operator configured with a vertical industry control center in the first device and a PLMN network operator have signed a service cooperation agreement, so that the first device can determine whether the vertical industry operator has the authority of opening a non-public network according to the service cooperation agreement. On the other hand, the first device may query from the PLMN network operator or the industry vertical control center whether the industry vertical operator has the right to open the non-public network. On the other hand, the vertical industry control center can also send information that the vertical industry operator and the PLMN network operator have signed a service cooperation agreement to the first device in the process of sending the first request message, so that the first device can conveniently determine that the vertical industry control center has the authority of opening the non-public network.

In an alternative embodiment, as shown in fig. 9, before step 104, the method provided in this embodiment further includes:

step 114, the access network management device determines the network area of the non-public network according to the coverage area of the non-public network.

Step 115, the access network management device determines the access device according to the network area of the non-public network.

In particular, since the access network management device may manage one or more access devices, the network area covered by each access device is different. Therefore, if the network area of the non-public network coincides with the area covered by a certain access device a or is located within the coverage area of the access device a, the access network management device may determine that the non-public network is provided by the access device a.

In an alternative embodiment, as shown in fig. 9, before step 102, the method provided in this embodiment further includes:

step 116, the first device determines the access network management device according to the coverage area of the non-public network and the configuration information of the management area of the one or more access network management devices.

Specifically, the first device determines, as the access network management device, a device that manages the non-public network in the one or more access network management devices according to the coverage area of the non-public network and the configuration information of the management area of the one or more access network management devices.

As shown in fig. 10, taking the first device as NVAF, the access network management device as RAN OAM, the access device as RAN, and the vertical industry control center as OT center as an example, a process that OT center requests a public network operator (taking PLMN network operator as an example) to establish a non-public network is described in detail, as shown in fig. 10, the method includes:

step 201, the OT center sends a non-public network service request (service request) to the NVAF. Wherein the non-public network service request comprises: the coverage area of the non-public network, the network access parameter of the non-public network, the time indication of the non-public network, the number segment of the vertical industry terminal user, the identification and/or address of the corresponding UDM network element, and the identification of the OTcenter. Since a public network operator may provide services for a plurality of different vertical industry operators, sending the identity of the OT center facilitates the NVAF to determine that the OTcenter indicated by the identity of the OT center opens or manages a non-public network.

It should be noted that, before performing step 201, the method provided in the embodiment of the present application further includes: the vertical industry operators and PLMN network operators have signed service cooperation agreements.

It should be understood that the non-public network service request is the first request message in the above embodiments.

Step 202, the NVAF performs authorization check on the non-public network service request, and determines whether to permit the non-public network service request.

Specifically, after receiving the non-public network service request, the NVAF determines whether the vertical industry operator has the right to open the non-public network. For example, if the NVAF determines that the vertical industry operator has entered into a business cooperation agreement with a PLMN network operator, the NVAF determines that the vertical industry operator has the right to open a non-public network. Otherwise, the NVAF determines that the vertical industry operator does not have the authority of opening the non-public network.

Step 203, the NVAF sends NF Registration request to the NRF, so that the NRF receives the NF Registration request from the NVAF. And the NF registration operation carries the identifier and/or address of the UDM network element and the number field of the vertical industry terminal user.

In the embodiment of the present application, step 203 is executed to enable the AMF network element managed by the PLMN network operator to find the UDM network element corresponding to the vertical industry operator through the NRF when the vertical industry terminal executes the network attach. And the AMF network element can further acquire authentication information and subscription data of the vertical industry terminal from the UDM network element corresponding to the vertical industry operator.

Step 204, the NRF sends a NF Registration response message (Registration response) to the NVAF, so that the NVAF receives the NF Registration response message from the NRF. The NF registration complete message is used to indicate that the NRF has completed the registration of the UDM network element corresponding to the vertical industry operator.

Step 205, the NVAF determines RAN OAM for managing the non-public network according to the coverage area of the non-public network and configuration information of one or more areas managed by the RAN OAM.

In step 206, the NVAF sends a Non-public network setup request (Non-public network setup request) to the RAN OAM, so that the RAN OAM receives the Non-public network setup request from the NVAF. Wherein, the non-public network setting request comprises: a coverage area of the non-public network, a network access parameter of the non-public network, a time indication of the non-public network.

Step 207, the RAN OAM sends a second configuration message to the RAN equipment, so that the RAN equipment receives the second configuration message. Wherein the second configuration message includes: a network access parameter of the non-public network, a time indication of the non-public network.

Step 208, the RAN device sends the broadcast message according to the second configuration message within the valid time period indicated by the time indication. Wherein, the broadcast message at least comprises: network access parameters of the non-public network.

In the embodiment of the present application, by performing step 208, the industry vertical terminal may select an access network to be accessed according to the network access parameter including the non-public network in the broadcast message by searching and parsing the broadcast message of the RAN device.

In step 209, the RAN OAM sends a Non-public network setup response (Non-public network setup response) to the NVAF, so that the NVAF receives the Non-public network setup response. The non-public network setup response is used to indicate that the non-public network setup is complete.

Step 210, the NVAF feeds back to the OT center that the non-public network service request has been successfully processed.

The method of the embodiment of the application can enable the vertical industry operator to open the non-public network to the PLMN network operator according to the requirement, so as to meet the network coverage requirement of the vertical industry operator, and meanwhile, the public network operator can increase the service mode and income source of the public network through cooperation of the vertical industry.

It should be understood that steps 201-210 take the example where the OT center requests the PLMN network operator to establish (may also be referred to as provisioning) a non-public network within the coverage of the non-public network specified by the OT center. If the OT center has requested the PLMN network operator to open the non-public network within the coverage of the non-public network specified by the OT center, the OT center may request the NVAF to update the non-public network service if the coverage and the validity period of the non-public network need to be changed subsequently. The specific process that the OT center can request the NVAF to update the non-public network service may refer to steps 201-210, which are not described herein. In a specific process that the OT center requests to update the non-public network service, the OT center sends information corresponding to the changed non-public network to the NVAF. For example, the changed coverage area and time indication corresponding to the non-public network and the network access parameter of the non-public network. Of course, the changed information corresponding to the non-public network may also be: and the information of the vertical industry terminal accessed to the non-public network, the information of the UDM network element and the like.

As shown in fig. 11, fig. 11 illustrates a specific process of accessing a non-public network by a terminal after a RAN device establishes or updates the non-public network for a vertical industry control center.

Step 301, the terminal selects the accessed non-public network according to the identifier supporting the non-public network contained in the broadcast message by searching and analyzing the broadcast message of the RAN device.

It should be understood that the terminal is configured with a user identifier (Type a user ID) used by the terminal to access the non-public network, an identifier of the non-public network. The specific identification format of the user is as follows: a00101234, network identification A001.

Step 302, RRC connection is established between the terminal and the RAN device.

The specific implementation of step 302 may refer to descriptions in the prior art, and is not described herein again.

Step 303, the terminal sends a Registration Request message (Registration Request) to the AMF network element. Wherein, the registration request message includes the user's identification.

And step 304, the AMF network element sends an authentication request message to the AUSF network element. The authentication request message is used to authenticate the terminal. For example, the authentication request message includes an identification of the user of the terminal.

Step 305, the AUSF network element sends a discovery request to the NRF. The discovery request is used for determining information of a UDM corresponding to the terminal. The discovery request includes a UDM type (type), and an identifier of the user. Wherein the UDM type is to inform the NRF that the network element it requests to discover is a UDM network element. It should be appreciated that the execution of the discovery request in step 305 facilitates the AUSF network element to determine the UDM network element corresponding to the terminal of the industry vertical.

Step 306, the NRF determines the UDM network element serving the terminal according to the identity of the user in step 305.

It should be understood that the NRF holds information (identification and network address, etc.) of the UDM for a vertical and number segment information (e.g., a 00100001-a 00109999) of the vertical user identification for the UDM service.

Step 307, the NRF provides the identifier and the network address information of the UDM network element serving the terminal to the AUSF network element.
