[0047] N4 interface: The N4 interface is between SMF and UPF and is the interface between the control plane and forwarding plane of the 5G core network.

[0048] Below, each step of the signaling sorting method for a customized network in this example implementation will be described in more detail with reference to the accompanying drawings and embodiments.

[0049] like Figure 2 As shown, according to an embodiment of the present disclosure, a signaling sorting method for a customized network includes:

[0050] Step S202: configure the IP address of the user plane function UPF of the customized network.

[0051] Among them, by configuring the IP address of UPF, the interconnection between the access network equipment of the customized network and the data network is achieved based on the IP address of UPF.

[0052] Step S204: Adaptively detect the IP address of the base station accessing the customized network based on the IP address of the UPF.

[0053] Among them, through the configured UPF IP address, the traffic data related to the UPF IP address can be obtained, so that based on the analysis of the traffic data, the base station IP address used to access the customized network can be obtained.

[0054] Step S206, obtaining the traffic of the N1 interface and / or the traffic of the N2 interface, the N1 interface is the interface between the terminal UE and the access and mobility management function AMF, and the N2 interface is the interface between the access network RAN ​​AMF.

[0055] The traffic on the N1 interface carries the interaction data between the UE and the AMF, and the traffic on the N2 interface carries the interaction data between the UE and the RAN.

[0056] In addition, the traffic of the N1 interface and / or the traffic of the N2 interface can be intercepted and obtained by a monitoring device set at a designated position of the splitter, or the N1 interface traffic and the N2 interface traffic can be separated in the splitter based on the IP address.

[0057] Step S208 , sorting the relevant traffic of the customized network from the traffic of the N1 interface and / or the traffic of the N2 interface based on the base station IP address of the customized network, so as to monitor the relevant traffic of the customized network.

[0058] In this embodiment, after obtaining the IP address of the UPF of the customized network, the base station and the IP address of the base station are configured based on the UPF IP address adaptive detection, so that the traffic data of the customized network can be sorted out from all N1 interface traffic and / or N2 interface traffic, and automatic sorting of designated signaling in the customized network is realized. Through the adaptive detection operation, it can adapt to the working conditions of frequent changes in the base station IP address of the customized network caused by operations such as service access scope and new sites, thereby reducing manual intervention and timely obtaining the changed base station IP address of the customized network. Furthermore, after obtaining the base station IP address of the customized network, it can sort out the interface traffic under the customized network from all detected N1 interface traffic and / or N2 interface traffic, which is beneficial to improving the sorting efficiency of designated signaling in the traffic, so as to further improve the alarm efficiency of abnormal signaling.

[0059] like Figure 3 As shown, in one embodiment, a specific implementation method of adaptively detecting the IP address of a base station accessing a customized network based on the IP address of the UPF in step S204 includes:

[0060] Step S302, obtain the traffic of the N4 interface, where the N4 interface is the interface connecting the UPF and the session management function SMF.

[0061] Specifically, by communicating with the network splitter, the traffic of the N4 interface is obtained at a specified position of the splitter.

[0062] Step S304: Adaptively identify the IP address of the base station accessing the customized network from the traffic of the N4 interface based on the IP address of the UPF.

[0063] In this embodiment, by acquiring the traffic data of the N4 interface, the routing and forwarding information of the base station IP address based on the customized network can be monitored from the traffic data of the N4 interface, and the base station IP address of the customized network can be identified from this information. If the base station IP address of the customized network changes, it can also be monitored and identified in time to further adjust the corresponding filtering in time.

[0064] like Figure 4 As shown, in one embodiment, in step S304, a specific implementation method of obtaining the traffic of the N4 interface at a specified position of the splitter includes:

[0065] Step S402: monitor the network PDU session establishment process or session modification process.

[0066] Step S404, identifying the N4SessionModification process initiated by SMF in the session establishment process or the session modification process.

[0067] Step S406: Obtain tunnel information in the N4 interface traffic based on the N4 Session Modification process.

[0068] In this embodiment, based on the monitoring of the interaction of the session establishment process or the session modification process, the traffic of the N4 interface can be obtained. For the traffic of the N4 interface, the frequently changing base station IP addresses are identified through automatic learning, and the related signaling is filtered by the base station IP address, which can reduce manual intervention and improve the efficiency of IP address updating.

[0069] For example, taking the administrative province as a network coverage unit, an automatic signaling sorting module is added to the computer room of the provincial center. By connecting to the splitter, the original N1 / N2 and N4 signaling traffic of the entire province is accessed, and the IP address of the UPF of the 5G customized network is input. The sorting module analyzes the relevant traffic of 2B (Industrial Internet, i.e. customized network) UPF in the N4 interface signaling in real time, and forms a dynamic list of IP addresses of customized network access base stations related to 2B UPF according to the base station tunnel information interacted in the N4 Session Modification process in the session establishment process or the session modification process. The traffic filtering rules are dynamically set according to the base station IP address to filter out the original N1 / N2 signaling traffic related to the 5G customized network.

[0070] like Figure 5 As shown, the PDU session establishment process involved in the signaling sorting solution of the customized network according to the present disclosure specifically includes:

[0071] Step 1 to step 5, the first interaction process specifically includes:

[0072] Step 1. The UE sends a PDU Session Establishment Request message to the AMF.

[0073] The message includes: S-NSSAI(s), DNN, PDU Session ID, Request type, N1 SMFcontainer (PDU Session Estabilishment Request) and other information.

[0074] Step 2: AMF executes the SMF selection process and selects the appropriate SMF according to the slice information.

[0075] When AMF receives the PDU Session Establishment Request message from UE and finds that a new PDU session is being created, it will execute the SMF selection process to select SMF for the PDU session. During the SMF selection process, AMF will interact with NSSF to obtain network slice information and select a suitable SMF through NRF.

[0076] Step 3: AMF sends a Nsmf_PDUSession_CreateSMContext Request message to SMF to request the establishment of a PDU session.

[0077] The message includes: SUPI, DNN, S-NSSAI, PDU Session ID, AMF ID, Request Type, N1 SMcontainer (PDU Session Establishment Request), User location information, AccessType, PEI, GPSI, Subscription For PDU Session Status Notification and other information.

[0078] Step 4: SMF initiates session registration to UDM and obtains contract information.

[0079] The contract information includes: SSC mode, Session AMBR, etc.

[0080] Step 5. SMF responds to AMF with Nsmf_PDUSession_CreateSMContext Response.

[0081] Depending on whether the session is successfully established, the message carries different parameters.

[0082] If the session establishment process is executed successfully and the SM context is created, the ID of the SM context is brought to the AMF in the Nsmf_PDUSession_CreateSMContext Response message.

[0083] If the session establishment process fails, the AMF is notified of the session process failure through the Cause in the message. The AMF releases the session-related resources and sends the N1 SM container (PDU Session Reject) to the UE.

[0084] Step 6: PDU Session authentication / authorization process.

[0085] Steps 7 to 9, the second interaction process, specifically include:

[0086] Step 7a: SMF executes the PCF selection function to select a suitable PCF.

[0087] SMF discovery is to discover and select a suitable PCF through NRF when creating a new PDU session.

[0088] Step 7b: SMF sends a PDU-CAN session establishment process to PCF.

[0089] PCF will send relevant QoS control policies, charging control policies, UPF selection policies and other information to SMF.

[0090] Step 8: SMF executes the UPF selection function to select a suitable UPF.

[0091] SMF selects UPF based on DNN, DNAI, user location information, etc.

[0092] Step 9: SMF initiates a Session Management Policy Modification message to PCF.

[0093] Carry the selected UPF information, assign the IP address to the UE, and obtain the control and charging policy required by the UPF.

[0094] Step 10. SMF initiates the N4 session establishment process to the UPF selected in step 8, including: step 10a. N4Session establishment / modification request, step 10a. N4 Session establishment / modification request.

[0095] This step is the process of obtaining N4 flow.

[0096] Various rules carried to UPF during the establishment process include PDR, URR, QER, BAR, and FAR.

[0097] Step 11 to step 15, the third interaction process, specifically includes:

[0098] Step 11. SMF sends a Namf_Communication_N1N2MessageTransfer message to AMF to request the transfer of N2 resources.

[0099] Carries N1 Container and N2 Container, where N1 Container is the PDU session establishment response that SMF replies to UE, and N2 Container is the resource establishment request initiated by SMF to RAN.

[0100] After completion, AMF sends a Namf_Communication_N1N2MessageTransfer_Ack message to SMF.

[0101] 12. AMF sends an N2 PDU Session Request message to the UE to request the establishment of an N2 PDU session, and transparently transmits the PDU Session Establish Accept message and the AN-specific resource setup message initiated by SMF to the (R)AN.

[0102] The PDU Session Establishment Accept carries the QoS Rule.

[0103] In the AN-specific resource setup, the media plane tunnel endpoint information of QoS Profile and UPF is carried.

[0104] 13. A resource connection is established between the (R)AN and the UE according to the AN-specific resource setup message.

[0105] 14. The (R)AN replies to the AMF with an N2 PDU Session Request Ack message, which carries the (R)AN side downlink media plane tunnel endpoint information.

[0106] 15. AMF sends Nsmf_PDUSession_UpdateSMContext Request message to SMF, carrying N2Container, which is the resource establishment response from (R)AN to SMF, including the media plane tunnel endpoint information on the (R)AN side.

[0107] 16. SMF initiates the N4 Session Modification procedure to UPF to negotiate the downlink media plane tunnel information on the (R)AN side, specifically including: step 16a, N4 Session modification request, step 16b, N4 Session modification response.

[0108] This step is also the process of obtaining N4 traffic.

[0109] Step 17 to step 20, the fourth interaction process, specifically includes:

[0110] 17. SMF replies Nsmf_PDUSession_UpdateSMContext Response message to AMF.

[0111] 18. The SMF session is established and the Nsmf_PDUSession_SMContextNotify message is sent to AMF.

[0112] 19. If the UE applies for an IPv6 type PDU session, SMF also needs to publish an IPv6 routing announcement to the UE through UPF.

[0113] 20. If the session establishment fails after step 4, SMF needs to initiate the deregistration and desubscription process to UDM.

[0114] like Figure 6 As shown, in one embodiment, in step S306, a specific implementation method of adaptively identifying the IP address of the base station accessing the customized network from the traffic of the N4 interface based on the IP address of the UPF includes:

[0115] Step S602, extracting the tunnel establishment and modification request of the N4 Session Modification process sent by SMF to UPF from the traffic of the N4 interface.

[0116] The tunnel establishment and modification request includes various rules carried to the UPF, including PDR, URR, QER, BAR, and FAR.

[0117] Among them, PDR (Packet Detection Rule) is the packet detection rule, URR (Usage Reporting Rules) is the usage reporting rule, QER (QoS Enforcement Rules Qos) is the QoS enforcement rule, BAR (Buffering Action Rules) is the buffering action rule, FAR (Forwarding Action Rules) is the forwarding behavior rule, etc.

[0118] Step S604: extract the base station tunnel information and message forwarding rules corresponding to the IP address of the UPF from the tunnel establishment and modification request.

[0119] Step S606: Identify the base station IP address of the customized network from the base station tunnel information and the message forwarding rule.

[0120] In this embodiment, by obtaining the interaction information between SMF and UPF during the establishment process of the N4 Session Modification process, the tunnel establishment and modification request of the N4 Session Modification process sent by SMF to UPF includes the negotiated (R)AN side downlink media plane tunnel information, or notifies UPF to update the tunnel information, so as to obtain the tunnel information and message forwarding rules of the base station during the interaction process, and then identify the base station IP address of the customized network according to the message forwarding path and tunnel information.

[0121] In one embodiment, a specific implementation of obtaining traffic on the N1 interface and / or traffic on the N2 interface includes:

[0122] At a specified position of the splitter, obtain the traffic of the N1 interface and / or the traffic of the N2 interface.

[0123] Among them, the splitter can separate the traffic of N1, N2 and N4 interfaces based on IP addresses, or it can be achieved through deep packet inspection DPI equipment.

[0124] In one embodiment, it specifically includes: determining a filtering policy corresponding to the base station IP address of the customized network, so as to filter the target signaling from the related traffic of the customized network based on the filtering policy.

[0125] In one embodiment, determining a filtering policy corresponding to the base station IP address of the customized network specifically includes: determining the IP segment to which the base station IP address of the customized network belongs; configuring a corresponding filtering policy for the IP segment to filter target signaling from relevant traffic of the customized network based on the filtering policy.

[0126] In this embodiment, by presetting multiple filtering strategies, each filtering strategy corresponds to an IP segment. When the base station IP address of the customized network changes frequently, the corresponding filtering strategy can be adjusted by detecting the IP segment after the change of the base station IP address of the customized network to ensure the timeliness of monitoring and alarming the traffic of the N1 interface and / or the traffic of the N2 interface.

[0127] like Figure 7 As shown, according to another embodiment of the present disclosure, a signaling sorting method for a customized network specifically includes:

[0128] Step S702: configure the IP address of the user plane function UPF of the customized network.

[0129] Step S704, obtaining the traffic of the N4 interface at the specified position of the splitter.

[0130] Step S706, monitoring the network PDU session establishment process or session modification process based on the traffic of the N4 interface.

[0131] Step S708, identifying the N4SessionModification process initiated by SMF in the session establishment process or the session modification process.

[0132] Step S710, extracting the tunnel establishment and modification request of the N4 Session Modification process sent by SMF to UPF from the traffic of the N4 interface.

[0133] Step S712: extract the base station tunnel information and message forwarding rules corresponding to the IP address of the UPF from the tunnel establishment and modification request.

[0134] Step S714: Identify the base station IP address of the customized network from the base station tunnel information and the message forwarding rule.

[0135] Step S716, at the specified position of the splitter, obtain the traffic of the N1 interface and / or the traffic of the N2 interface, the N1 interface is the interface between the terminal UE and the access and mobility management function AMF, and the N2 interface is the interface between the access network RAN ​​and the AMF.

[0136] Step S718: sorting the relevant traffic of the customized network from the traffic of the N1 interface and / or the traffic of the N2 interface based on the base station IP address of the customized network, so as to monitor the relevant traffic of the customized network.

[0137] Step S720: determine the IP segment to which the base station IP address of the customized network belongs.

[0138] Step S722, configuring a corresponding filtering policy for the IP segment to filter target signaling from related traffic of the customized network based on the filtering policy.

[0139] In this embodiment, by setting up a signaling automatic sorting module processing mechanism, the N1 / N2 and N4 interface traffic accessing the entire network is obtained, the IP address of the 2B UPF is configured, the 2B UPF-related traffic in the N4 interface traffic is analyzed in real time, the N4 Session Modification process of the interaction between SMF and UPF in the session establishment process or the session modification process is identified, the base station IP address in the base station tunnel information in the interaction information is recorded, and the base station IP address table corresponding to the 2B UPF is dynamically formed. The filtering rules are dynamically adjusted according to the automatically learned base station IP address to filter out the related N1 / N2 traffic. By parsing the N4 interface traffic related to the 2B UPF, the base station tunnel information of the N4 SessionModification process interaction between 2B UPF and SMF in the session establishment process or the session modification process is extracted, and the dynamic address table of the base stations related to the 5G customized network is automatically formed to solve the problems of much manual participation, low efficiency, and inability to update in time in the signaling sorting based on the base station engineering parameter configuration in the related technology.

[0140] It should be noted that the above figures are only schematic illustrations of the processes included in the method according to an exemplary embodiment of the present invention, and are not intended to be limiting. It is easy to understand that the processes shown in the above figures do not indicate or limit the time sequence of these processes. In addition, it is also easy to understand that these processes can be performed synchronously or asynchronously, for example, in multiple modules.
