Description

5G network communication control method, device, platform and system

Technical Field

The embodiment of the invention relates to the field of communication, in particular to a 5G network communication control method, a device, a platform and a system.

Background

According to the regulations of the network security law, operators usually need to cooperate with communication control instructions issued by special government agencies to take communication restriction measures (such as communication shielding for users in a specific area) for the purpose of maintaining national security and social public order and dealing with major sudden social security events. In general, the specific area only relates to a part of area in one or more provinces, and the area range is small, which puts high requirements on the precision of taking communication limitation measures; meanwhile, as the precondition for taking the communication restriction measures is usually emergency treatment for emergencies, the urgency requirement is high, and the processing process of the communication restriction measures is required to have high efficiency. Currently, when a communication restriction measure is taken based on a third Generation mobile communication technology (3G) network and a fourth Generation mobile communication technology (4G) network, a communication regulation instruction is issued to a corresponding communication device in a specific area, and a communication restriction measure is taken for a user in the specific area through the corresponding communication device in the specific area, so as to meet the above requirements of accuracy and urgency.

A fifth Generation mobile communication technology (5th-Generation, 5G) network is deployed based on a service architecture by using a stand-alone (SA), and can execute instructions related to communication restriction measures through an access and mobility management function (AMF) and a Session Management Function (SMF). However, in practical situations, most of 5G networks are deployed in a centralized or regional manner, and the AMF and the SMF usually cover all areas within one province or simultaneously cover multiple province areas, which makes it difficult to achieve the above accuracy requirement when a communication restriction measure is taken based on the 5G network; on the other hand, if a network element dedicated to implementing the communication restriction measure is set in order to improve the accuracy of the 5G network in taking the communication restriction measure, because an emergency for taking the communication restriction measure is generally a low-probability event, a problem of network resource waste due to long-term idle of the device occurs.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. The use of the terms first, second, etc. do not denote any order, and the terms first, second, etc. may be interpreted as names of the objects described. In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Before introducing the embodiment of the present invention, a simple introduction is first performed on a mode in which a current operator side takes a communication restriction measure for a user in a specific area, a network architecture of a 5G network that adopts SA networking based on a Service Based Architecture (SBA), and a user service request flow based on the network architecture.

Specifically, a manner in which the operator side takes a communication restriction measure for the user in a specific area at present is first described. Referring to fig. 1, when receiving a communication control instruction, a network control platform of an operator issues the communication control instruction to a Mobile Switching Center (MSC), an Access Gateway Controller (AGCF), and a Session Border Controller (SBC) or a proxy-call session control function (P-CSCF) in a specific area by issuing an instruction or manually processing the communication control instruction. The MSC sends the communication control instruction to a base station corresponding to the MSC so that the base station can limit the communication of the wireless communication users in a specific area; the AGCF sends the communication control instruction to Integrated Access Device (IAD) so that the IAD can carry out communication limitation on the IAD fixed telephone of the H.248 protocol in a specific area; the SBC or the P-CSCF issues the communication regulation instruction to an Optical Network Unit (ONU) device, so that the ONU limits communication with a fixed telephone and a terminal of a Session Initiation Protocol (SIP) in a specific area.

Fig. 2 is a network architecture diagram of a 5G network adopting SA networking based on a service architecture, and referring to fig. 2, the 5G network adopting SA networking based on the service architecture includes the following network element functional entities: a 5G (wireless) access network (R) AN), a User Equipment (UE), a User Plane Function (UPF), a Data Network (DN), and a network element function entity in a 5G core network. Wherein, the network element functional entity in the 5G core network comprises: AMF, SMF, authentication service function (AUSF), Network Slice Selection Function (NSSF), network capability open function (NEF), network element data repository function (NF relocation function, NRF), Policy Control Function (PCF), unified data management function (UDM), and application layer function (AF). The network element functional entity has the following specific functions: the AMF is used for being responsible for access and mobility management of users; the SMF is used for being responsible for session management of the user; AUSF is responsible for authenticating 3GPP and non-3 GPP access of users; the UPF is used for being responsible for user plane processing; the DN is responsible for data networks such as operator services, internet access or third party services; the NSSF is used for selecting the network slice adopted by the user service; 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; the PCF is used for being responsible for the policy control of the user, including the policy of the session, the mobility policy and the like; the UDM is used for being responsible for subscription data management of the user; the AF is responsible for interworking with the core network to provide services to the user. The connection relationship of the network element functional entities is as follows: the UE is connected with the AMF through AN N1 interface, (R) the AN is connected with the AMF through AN N2 interface, (R) the AN is connected with the UPF through AN N3 interface, the UPF is connected with the SMF through AN N4 interface, the interior of the UPF transmits data through AN N9 interface (data are transmitted between AN uplink classifier UPF and AN anchor UPF through AN N9 interface), the UPF is connected with the DN through AN N6 interface, AN IT bus is adopted in the service framework, the AMF is accessed to the bus through a service-based interface Namf, the AUSF is accessed to the bus through a service-based interface Nausf, the SMF is accessed to the bus through a service-based interface Nsmf, the NSSF is accessed to the bus through a service-based interface Nssf, the NEF is accessed to the bus through a service-based interface Nnef, the NRF is accessed to the bus through a service-based interface Nmdm, and the PCF is accessed to the bus through a service-based interface Napcf.

Based on the network architecture shown in fig. 2, the process of initiating a service request by a user is as follows: a user sends a non-access stratum (NAS) message to an AMF through a UE, where the NAS message carries a session establishment request (PDU (Protocol Data Unit), slice selection assistance information (NSSAI), and a Data Network Name (DNN); after receiving the NAS message, the AMF selects an SMF according to the NSSAI and the DNN, and finishes a service request process through the SMF.

Therefore, the deployment modes of the 3G network and the 4G network are completely different from the deployment mode of the 5G network, and if a mode of performing communication restriction measures in the 3G network or the 4G network is used for reference, that is, a communication control instruction is sent to a communication access device in a specific area, and then the communication restriction measures are performed on users accessing the communication access device through the communication access device, since the 5G network initiates a service request process through the AMF and the SMF, it can be considered that the communication restriction measures are performed on the users in the specific area through the AMF and the SMF. However, in practical situations, since a 5G network is mostly deployed in a centralized or regional manner, the AMF and the SMF usually cover all areas within one province or simultaneously cover multiple provinces, and there is a problem that the coverage of the AMF and the SMF is too large and seriously does not conform to a specific area, so that all users within the coverage of the AMF and the SMF are inevitably affected by the communication restriction measure and cannot normally communicate, and it is difficult to achieve a higher accuracy requirement in the communication restriction measure; on the other hand, if a network element dedicated to implementing the communication restriction measure is set in order to improve the accuracy of the 5G network in taking the communication restriction measure, because an emergency for taking the communication restriction measure is generally a low-probability event, a problem of network resource waste due to long-term idle of the device occurs.

Based on the existing problems, an embodiment of the present invention provides a 5G network communication control method, which is applied to a 5G network (as shown in fig. 2) deployed by using an independent networking SA, where the 5G network includes a 5G core network and at least one New Radio (NR) device, and at least one 5G NR device directly accesses the 5G core network, in a specific implementation, the 5G NR device is a device (e.g., a 5G base station) on which a 5G NR is disposed, and the 5G NR device directly accesses the 5G core network through the 5G NR. Specifically, referring to fig. 3, a method provided by an embodiment of the present invention includes:

step S310: the 5G network communication regulation platform receives at least one communication regulation instruction; wherein each communication regulation instruction at least comprises: regulatory domain location information, and regulatory time.

At least one communication regulation instruction is an instruction related to communication regulation and issued to an operator by a special government organization through a communication management bureau. Specifically, each communication regulation instruction may include information related to communication regulation, such as regulation area location information, regulation time, a regulation user identifier (e.g., identification information capable of uniquely identifying a user, such as a Subscriber Identity Module (SIM) card number), a regulation service identifier, and the like. In an embodiment of the present invention, each communication regulation instruction at least includes: the area location information, and the regulation time are regulated so as to specify the area and the time range in which the communication restriction measure needs to be performed. Wherein the regulatory region location information may include any one of: cell identification, and geographic coordinates of the regulated area. The cell identifier may be information capable of uniquely identifying a cell, such as a cell ID, and the geographic coordinates of the regulated area may be longitude and latitude corresponding to the regulated area, so as to identify location information of the regulated area. It is to be understood that the above-mentioned listed regulated area location information is only exemplary, and in specific implementation, the information form of the regulated area location information is not limited in the embodiments of the present invention, as long as the location of the regulated area can be located, for example, in specific implementation, the regulated area location information may be mapped to a location parameter that can be identified by the network, and then the location parameter is used as the regulated area location information.

After receiving at least one communication regulation instruction, the embodiment of the present invention may execute the communication regulation task in two parts according to the communication regulation instruction, where the execution process of one part (hereinafter referred to as a first part) corresponds to the subsequent steps S320 to S324, and the execution process of the other part (hereinafter referred to as a second part) corresponds to the subsequent steps S330 to S332. In a specific implementation, the first part and the second part are executed independently.

Step S320: the 5G network communication control platform determines a target 5G NR device according to the first control area position information in the first communication control instruction, and sends the first communication control instruction to the target 5G NR device.

Specifically, the target 5G NR device is located within the regulated area corresponding to the first regulated-area location information. When determining the target 5G NR device according to the first regulatory region location information in the first communication regulatory instruction, first determining a first regulatory region coverage area corresponding to the first regulatory region according to the first regulatory region location information, then taking the 5G NR device in the first regulatory region coverage area as the target 5G NR device, and performing step S321. In a specific implementation, a manner of determining a coverage area of the first controlled area corresponding to the first controlled area according to the location information of the first controlled area may be set by a person skilled in the art according to an actual situation, which is not limited in the embodiment of the present invention.

Step S321: the target 5G NR device receives a first communication regulation instruction sent by the 5G network communication regulation platform.

Step S322: the target 5G NR device determines at least one target user according to the first communication regulation instruction.

Specifically, in this step, at least one target user may be determined according to the service type or the customized information related to the first communication regulation instruction, and then step S323 is performed.

For example, the first communication regulation instruction may include customized information, for example, in an alternative, the first communication regulation instruction includes a regulation user identifier, and a user corresponding to the regulation user identifier may be directly used as a target user.

Or, if the first communication regulation instruction does not include the regulated user identifier, all users accessing the target 5G NR device may be defaulted as registered users, and then at least one target user is determined according to the service type. For example, in an alternative, if it is determined that the first communication regulation instruction does not include the regulation user identifier, the steps shown in fig. 4 may be performed:

step S410: a data network name of at least one registered user is obtained.

The registered user is a user who has completed network slice registration through the target 5G NR device, and the manner of acquiring the data network name may be set by a person skilled in the art according to an actual situation, which is not limited in the embodiment of the present invention.

Step S420: determining the service type of the target registered user according to the data network name of the target registered user; the target registered user is any one of at least one target user.

Specifically, the corresponding relationship between the data network name and the service type may be preset, and then the service type corresponding to the data network name of the target registered user is determined as the service type of the target registered user according to the corresponding relationship. The service types may include: internet of things services, enterprise network services, and common services other than internet of things services and enterprise network services.

Step S430: and judging whether the service type of the target registered user does not belong to the non-target service type.

Wherein the non-target traffic types include: internet of things services, and enterprise network services. In the specific implementation, if the determination result is yes, that is, when it is determined that the service type of the target registered user does not belong to the non-target service type, step S440 is executed; if the determination result is negative, that is, when it is determined that the service type of the target registered user belongs to the non-target service type, step S450 is executed.

Step S440: and taking the target registered user as the target user.

In this step, the target registered user whose service type does not belong to the non-target service type is taken as the target user.

Step S450: and determining that the target registered user is not the target user, and ending the process.

Step S323: the target 5G NR device sends a network slice re-registration message to at least one target user.

In a specific implementation, the target 5G NR device may deregister information about a network slice that the at least one target user has registered, and then send a network slice re-registration message to the at least one target user to request the at least one target user to re-register the network slice network element.

Step S324: and the target 5G NR device receives a network slice registration message which is sent by at least one target user according to the network slice re-registration message and carries the auxiliary information of requesting slice selection.

Specifically, after receiving the network slice re-registration message, at least one target user re-initiates a network slice registration procedure, and sends a network slice registration message carrying request slice selection assistance information (requested NSSAI) to the target 5G NR device.

Step S330: the 5G network communication regulation platform sends a first communication regulation instruction to the 5G core network.

Step S331: and the 5G core network receives the first communication regulation instruction and generates a regulation slice network element.

Wherein the first communication regulation instruction at least comprises: first regulatory region location information, and a regulatory time. After receiving the first communication regulation instruction, the 5G core network instantiates the regulation slice network element.
