Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

Before introducing the embodiments of the present invention, first of all, the current way that the operator side takes communication restriction measures for users in a specific area, the network architecture of the 5G network using SA networking based on service based architecture (SBA), and the network architecture based on SA networking. The user service request process of the above network architecture is briefly introduced.

Fig. 1 shows the way that operators take communication restriction measures for users in a specific area at present. When the operator's network control platform receives the communication control request, it issues the communication control command to the mobile switching center (MSC) and the access gateway controller ( accessgateway control function, AGCF), and a session border controller (session border controller, SBC) or a proxy-call session control function (proxy-call session control function, P-CSCF), the MSC issues a communication control command to the MSC corresponding to the base station, so that the base station can restrict the communication of wireless communication users in a specific area; and, the AGCF issues the communication control command to the integrated access device (IAD), so that the IAD can control the H.248 protocol in the specific area and the SBC or the P-CSCF issues the communication control command to the optical network unit (ONU) device, so that the ONU can control the session initiation protocol (SIP) in a specific area. ) fixed telephones and terminals for communication restrictions.

Figure 2 is a schematic diagram of the network architecture of a 5G network using SA networking based on a service-oriented architecture. Referring to Figure 2, a 5G network using SA networking based on a service-oriented architecture includes the following network element functional entities: 5G (wireless) access network ((radio)access network, (R)AN), user equipment (UE), user plane function (UPF), data network (DN), and network element functions in the 5G core network entity. Among them, the network element functional entities in the 5G core network include: AMF, SMF, authentication server function (AUSF), network slice selection function (NSSF), network exposure function (NEF) , network element data warehouse function (NF repository function, NRF), policy control function (policy control function, PCF), unified data management function (unified data management, UDM), and application layer function (application function, AF). The specific functions of the above-mentioned network element functional entities are as follows: AMF is used for user access and mobility management; SMF is used for user session management; AUSF is used for user authentication for 3GPP and non-3GPP access; UPF is responsible for user plane processing; DN is responsible for data networks, such as operator services, Internet access or third-party services; NSSF is responsible for selecting network slices for user services; NRF is responsible for registration, discovery and selection of network functions ;NEF is responsible for opening the capabilities of the 5G network to external systems; PCF is responsible for user policy control, including session policy, mobility policy, etc.; UDM is responsible for user subscription data management; AF is responsible for and core Internet interoperability provides services to users. The connection relationship of the above-mentioned network element functional entities is as follows: UE is connected to AMF through N1 interface, (R)AN is connected to AMF through N2 interface, (R)AN is connected to UPF through N3 interface, UPF and SMF are connected through N4 interface, and the internal UPF is connected through N4 interface. Data is transmitted through the N9 interface (data is transmitted between the uplink classifier UPF and the anchor UPF through the N9 interface), the UPF and the DN are connected through the N6 interface, the IT-based bus is used in the service-oriented architecture, and the AMF is connected to the above through the service-based interface Namf Bus, AUSF accesses the above bus through the service-based interface Nausf, SMF accesses the above-mentioned bus through the service-based interface Nsmf, NSSF accesses the above-mentioned bus through the service-based interface Nssf, NEF is connected to the above-mentioned bus through the service-based interface Nnef, The NRF is connected to the above bus through the service-based interface Nnrf, the PCF is connected to the above-mentioned bus through the service-based interface Npcf, the UDM is connected to the above-mentioned bus through the service-based interface Nudm, and the AF is connected to the above-mentioned bus through the service-based interface Naf.

Based on the network architecture shown in FIG. 2, the user initiates a service request process as follows: the user sends a non-access stratum (NAS) message to the AMF through the UE, where the NAS message carries a session establishment request (PDU (Protocol Data Unit, Protocol Data Unit). Data unit) session establishment request), slice selection assistance information (NSSAI), and data network name (datanetwork name, DNN); after receiving the above NAS message, AMF selects SMF according to NSSAI and DNN, and The business request process is completed through the SMF.

It can be seen that the deployment method of 5G network is completely different from that of 3G network or 4G network. If we learn from the method of implementing communication restriction measures in 3G network or 4G network, that is, by sending communication control commands to access network equipment in a specific area, Then, the above-mentioned access network equipment is used to implement communication restriction measures for users accessing the access network equipment. Since the 5G network initiates the service request process through AMF and SMF, it can be considered to implement communication restrictions on users in a specific area through AMF and SMF. measure. However, in practice, since 5G networks are mostly centralized or regionally deployed, AMF and SMF usually cover the entire area in a province or cover multiple provinces at the same time. There is a problem that the coverage of AMF and SMF is too large and serious in specific areas. Therefore, it is inevitable that all users within the coverage of AMF and SMF will be affected by the communication restriction measures and cannot communicate normally, which will affect a large range of users, and the control accuracy will be low.

In order to solve the above problems, first of all, an embodiment of the present application provides a communication system, the communication system is a 5G communication system, and its network structure is shown in FIG. 3 , the 5G network is deployed in an independent networking SA, and the 5G network includes : 5G core network equipment 10 , 5G access network equipment 20 , and user equipment 30 .

Embodiment 1,

A 5G network communication control method provided by the embodiments of this application is applied to a 5G network communication control device. The 5G network communication control device may be a 5G access network device 20 or a chip in the 5G access network device 20. The implementation of the method by the 5G access network equipment is described as follows. As shown in Figure 6, the 5G network communication control method specifically includes the following steps:

S601. Receive a control command.

Wherein, the control order includes: control area information.

The control command can be generated by the operator according to the communication control requirements of the relevant departments. After receiving the control request, the operator can send the generated control command to all 5G access network devices 20 to trigger the 5G access network devices. 20 Execute the 5G network communication control method in the embodiment of the present application.

The control order may include control area information, and may also include one or more of necessary information related to communication control, such as control time, control user ID, control strategy, etc., according to the information carried in the control requirements of the relevant departments.

The control area information may be information that can locate the location of the control area, such as cell identifiers, geographic coordinates of the control area, and the like. Exemplarily, the control area information may be a cell ID, latitude and longitude coordinates corresponding to the control area, and the like.

The control time may be the start and end time and the like. Exemplarily, the control time may start at 9:00 and end at 19:00.

The area where the communication control measures are to be implemented and the implementation time of the communication control can be determined through the control area information and the control time. When the control message includes the control time, after receiving the control command, the 5G access network device 20 may perform subsequent steps at the start of the control time, stop the control process after the control time ends, or start the control process after receiving the command Perform subsequent steps, and stop the control process when the control duration meets the control time; when the control message does not contain the control time, the 5G access network device 20 may continue to perform the subsequent control steps until receiving a control stop command.

The regulated user identity can be the mobile phone number of the user, the international mobile subscriber identification number (IMSI) of the user equipment 30, the international mobile equipment identity of the user equipment 30 (international mobile equipment identity, IMEI), etc. are uniquely capable of identifying Information about the identity of the user or user equipment 30 .

By regulating the user identification, the 5G access network device 20 can more accurately identify the user group that needs to be regulated. When the regulated user ID is included in the control command, it indicates that a specific user or a specific user group needs to be regulated. At this time, the 5G access network device 20 can identify the specific user or specific user group according to the regulated user ID for communication control; When the control command does not contain the control user identifier, it indicates that all users in the control area corresponding to the control area information need to be controlled, and the 5G access network device 20 can control all users in the control area according to the control command.

The control strategy may be formulated by the relevant department according to the actual situation, formulated by the operator according to the control requirements, or pre-set by the operator in the 5G core network device 10 . Exemplarily, the control policy may be to limit the calls of the regulated user, limit the data connection of the regulated user, completely limit the communication of the regulated user, give different communication rights according to different regulated user IDs, and so on.

The users who need to be regulated and how to regulate the users can be determined through the regulation policy and the regulation user ID, so as to realize the regulation of the users in different ways according to the actual regulation requirements.

According to the actual situation, after receiving the control request, the operator can screen the target 5G access network device 20 that can cover the control area corresponding to the control area information according to the control area information. At this time, the operator only needs to send the control command to the target 5G access network device 20 without sending it to all 5G access network devices 20 .

S602. Determine the target user according to the control area information.

The target user is located in the control area corresponding to the control area information.

After receiving the control command, the 5G access network device 20 first determines the target users to determine the users who may need to be regulated in the control area. Optionally, when the control command includes the control time, the target user is determined according to the control area information at the start of the control time.

When a control time is included in the control order, it indicates that the control user needs to be controlled for communication within a specific time. Meanwhile, in the actual environment, the user may move continuously, and the user may move from within the control area to outside the control area, or from outside the control area into the control area. Therefore, when the control command includes the control time, the 5G access network device 20 only needs to start determining the target users in the control area when the start time of the control time arrives, so as to ensure that only users who are located in the control area during the control time are monitored. control. For a user who enters the coverage area of the 5G access network device 20 after the start of the control time, it can be determined whether the user is a target user in the control area after the user completes the handover or access process.

Optionally, it is determined that the overlapped part of the coverage area of the 5G access network device 20 and the control area corresponding to the control area information is the target area, and the users within the coverage area are determined to be the target users.

When the 5G access network device 20 determines that its coverage area overlaps with the control area, it is considered that the 5G access network device 20 can cover the control area corresponding to the control area information. At this time, in order to obtain a better control effect, All users within the coverage area of the 5G access network device 20 can be determined as target users that may need to be regulated.

Optionally, it is determined that the overlapped part of the coverage area of the 5G access network device 20 and the control area corresponding to the control area information is the target area, and the users in the target area are determined to be the target users.

The 5G access network device 20 can obtain geographic location information such as the latitude and longitude corresponding to the cell ID, sector, etc. in its own coverage area stored in the device, and map the geographic location information into parameters that the network can recognize to determine its own coverage area. Whether the control area corresponding to the control area information overlaps, so as to determine whether it can cover the control area. When there is no overlap between its own coverage area and the control area, it indicates that the 5G access network device 20 does not need to perform communication control, and the 5G access network device 20 can continue the normal working process.

When the coverage area of the 5G access network device 20 overlaps with the control area, it indicates that the 5G access network device 20 needs to perform communication control. The overlapping part of the control area is used to determine the target area that needs to be regulated in the coverage area of the 5G access network device 20, and avoid causing communication to users who are in the coverage area of the 5G access network device 20 but not in the control area. influences.

Exemplarily, the 5G access network device 20 may be a 5G base station, and its coverage area includes three areas: A, B, and C. The control area corresponding to the control area information may be the D area, and the control time may start at 9:00 and end at 19:00. . After receiving the control order, the 5G base station obtains the geographic location information of the three areas A, B, and C, and determines the overlapping parts of the A, B and D areas, and the non-overlapping parts of the C and D areas. The area is the target area, and when the current time is 9:00, all users in the current areas A and B are determined as the target users.

S603. Send a re-registration message to the user equipment of the target user.

By sending a re-registration message to the user equipment 30 of the target user, the user equipment 30 of the target user is made to send a registration message to the 5G access network device 20 .

S604: Receive a registration message sent by the user equipment of the target user according to the re-registration message.

After receiving the re-registration message, the user equipment 30 of the target user will initiate a re-registration process, and send a registration message, such as a registration message carrying information such as a user ID, to the 5G access network device 20 .

S605. When it is determined that the target user is a regulated user according to the regulated command and the registration message, route the registration message of the regulated user to the regulated network element.

After receiving the registration message sent by the target user, the 5G access network device 20 can further identify the target user according to the control command and the registration message, and determine the regulated user who needs to perform communication control, so as to avoid affecting the communication of the unregulated user. .

After completing the identification of the regulated user, the 5G access network device 20 routes the registration message of the regulated user to the regulated network element, so that the regulated network element selects a corresponding regulation policy to regulate the regulated user according to the registration message. The 5G access network device 20 may acquire information about the control network element that is preset or carried in the control command, so as to route the registration message of the control user to the control network element. The control network element may be pre-configured in the 5G core network device 10 or deployed through a virtualized instance after receiving a corresponding control command, such as a control network element such as GZ-AMF/GZ-SMF.

Optionally, the control command further includes: a control user ID, and the registration message includes: a user ID. The 5G access network device 20 may determine that the user ID in the registration message is the same as any control user ID in the control command, and then determine the target user. for regulated users.

When a regulated user ID is included in a policing order, it indicates that a specific user or group of users needs to be regulated. At this time, the 5G access network device 20 can identify the target user according to the regulated user ID and the user ID in the registration message sent by the user equipment 30 of the target user, and use the target user whose user ID is the same as any regulated user ID as the regulated user .

Exemplarily, the user identification may be a mobile phone number, and the control command includes the mobile phone number of the user who needs to be regulated. The 5G access network device 20 obtains the mobile phone number of the controlled user in the control command, and obtains the mobile phone number carried in the registration message sent by the user equipment 30 of the target user, compares the mobile phone number of the target user and the mobile phone number of the controlled user, and compares the mobile phone number with The target user with the same mobile phone number as the regulated user is the regulated user.

Optionally, the 5G access network device 20 may determine the target user located in the control area corresponding to the control area information as the control user according to the control command and the registration message.

When the control command does not contain the control user identifier, it indicates that all users in the control area corresponding to the control area information need to be controlled.

Optionally, in some scenarios of the 5G network, there may be a large number of IoT users or enterprise network users accessing the 5G network through the 5G access network device 20. These users do not need to perform communication control, and these users are subject to Regulation may cause unnecessary losses, such as applications such as the Internet of Vehicles that are conducting autonomous driving, and enterprise network users who are processing important data. At this time, the operator can configure the 5G access network device 20 according to the control requirements or actual conditions, so that the 5G access network device 20 can control users of a specific service type. Of course, in this case, the control command may not include the control user ID.

In this way, the 5G access network device 20 also needs to determine the service type of the target user to determine the regulated user among the target users. When all target users need to be regulated, user groups are differentiated by service types to avoid affecting some user groups that require communication guarantees. Specifically, the operator can preset the correspondence between the data network name and the service type in the 5G access network device 20 according to the actual situation, and the 5G access network device 20 can determine the service corresponding to the data network name of the target user according to the above-mentioned correspondence Type as the business type of the target user. Exemplarily, the above-mentioned service types may include: Internet of Things services, enterprise network services, and ordinary services other than the Internet of Things services and enterprise network services, and the like. The 5G access network device 20 may obtain the data network name carried in the registration message sent by the user equipment 30 of the target user, that is, the DNN identifier, to determine the service type of the target user.

Then, when it is determined that the service type of the target user belongs to the regulated service type, the target user is determined to be a regulated user. When it is determined that the service type of the target user belongs to the regulated service type, it is judged that the target user does not belong to the user group that needs communication guarantee, such as Internet of Things users, enterprise network users, etc. At this time, the target user can be identified as a regulated user. When it is determined that the service type of the target user is the Internet of Things service or the enterprise network service, it is determined that the target user belongs to the user group that needs communication guarantee, the target user is determined to be an unregulated user, and the registration message of the user is routed to the normal network element. Wherein, the types of regulated services may include: ordinary services other than Internet of Things services and enterprise network services.

Optionally, when the 5G access network device 20 determines that the target user is an unregulated user according to the control command and the registration message, it indicates that the user does not need to be regulated. At this time, the 5G access network device 20 can route the user's registration message. The normal network element to the 5G core network device 10 may be, for example, the AMF/SMF instantiated by the 5G core network device 10, so that the user can communicate normally after completing the registration process.

As shown in FIG. 6 , the 5G core network device 10 or the chip in the 5G core network device 10 can control the regulated users determined by the 5G access network device 20 according to the following method.

S606. Receive a control command.

After receiving the control order, the 5G core network device 10 can determine how to carry out the control according to the information carried in the control order.
