Abstract
Description
Technical Field
[0001] This application relates to the field of communication technologies, and in particular, to a method, device, and storage medium for split traffic management. Background Art
[0002] When a user terminal performs a network handover, if there is no direct transmission tunnel between corresponding base stations, in order to ensure the continuity of data transmission during the network handover process, a non-direct transmission tunnel needs to be established, and the traffic during the handover process is transmitted through the non-direct transmission tunnel. Specifically, it is necessary to establish a non-direct transmission tunnel based on the user plane network element of the first network (the network to be handed over) as an intermediate node.
[0003] Before the user terminal successfully completes the network handover, the downlink data link of the second network (the target network corresponding to the network to be handed over) has not been fully established successfully, and the user plane network element has been disconnected. The downlink traffic can only be transmitted to the user terminal through the non-direct transmission tunnel, that is, the user plane network element will perform split traffic management on the traffic of the second network and include the traffic of the second network in the traffic bill of the first network, resulting in cross management of the traffic of the second network and increasing the management cost of the convergence network element for this user plane network element. Summary of the Invention
[0004] The main purpose of this application is to provide a method, device, and storage medium for split traffic management, aiming to solve the technical problem of the relatively high management cost of the convergence network element for this user plane network element.
[0005] To achieve the above object, this application provides a method for split traffic management, and the method for split traffic management includes the following steps:
[0006] Determine whether there is a split rule in the user plane network element of the non-direct transmission tunnel;
[0007] Wherein, the non-direct transmission tunnel is established based on the user plane network element in the first network during the process of the user terminal switching from the first network to the second network;
[0008] If there is, send an update command to the user plane network element, and the update command is used to instruct the user plane network element to remove the network-side related attribute information by executing the update command.
[0009] This application is applied to a converged network element. Since the user plane network element will have a cross - impact on the management of the traffic of the second network before the user terminal successfully completes the network handover, during the process of the user terminal switching from the first network to the second network, after determining that there is a traffic splitting rule in the user plane network element of the non - direct transmission tunnel established based on the user plane network element in the first network, an update command is sent to the user plane network element. By executing the update command, the user plane network element removes the network - side related attribute information. That is, when the user plane network element receives traffic, due to the absence of network - side related attribute information, the user plane network element will not perform traffic splitting management on it, and thus will not have a cross - impact on the management of the traffic of the second network, thereby reducing the management cost of the converged network element for this user plane network element.

[0015] The realization, functional features and advantages of the purpose of this application will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.
[0017] Refer to Figure 1 , Figure 1 It is the process schematic diagram of the first embodiment of the traffic splitting management method of this application.
[0018] In the first embodiment, the traffic splitting management method includes the following steps:
[0019] S10: Determine whether there is a traffic splitting rule in the user plane network element of the non - direct transmission tunnel, where the non - direct transmission tunnel is established based on the user plane network element in the first network during the process of the user terminal switching from the first network to the second network;
[0020] It should be noted that the execution entity of the method in this embodiment is a convergence network element. Specifically, the convergence network element may include a network element for managing sessions in the first network, or a network element for managing traffic in the first network; the convergence network element may also include a network element for managing traffic in the second network.
[0021] When the user terminal performs network handover, if there is no direct transmission tunnel between the corresponding base stations, in order to ensure the continuity of data transmission during the network handover process, a non-direct transmission tunnel needs to be established, and the traffic during the handover process is transmitted through the non-direct transmission tunnel. Specifically, it is necessary to establish a non-direct transmission tunnel based on the user plane network element of the first network (the network to be handed over) as an intermediate node.
[0022] Before the user terminal successfully completes the network handover, the downlink data link of the second network (the target network corresponding to the network to be handed over) has not been fully established successfully, and the user plane network element has been disconnected. The downlink traffic can only be transmitted to the user terminal through the non-direct transmission tunnel. That is, the user plane network element will perform traffic management on the traffic of the second network and include the traffic of the second network in the traffic bill of the first network, resulting in cross management of the traffic of the second network and increasing the management cost of the convergence network element for this user plane network element.
[0023] It should be noted that the first network includes 5G (fifth-generation mobile communication) network, future 6G (sixth-generation mobile communication) network, etc., and the second network includes 4G (fourth-generation mobile communication) network, LTE (Long Term Evolution) network, etc. The user plane network element is used for routing and forwarding data packets, which is not limited here.
[0024] Furthermore, different networks support different traffic splitting rules. For example, the 5G network supports the ULCL traffic splitting rule, while the current 4G network does not support traffic splitting rules, that is, it does not support the ULCL traffic splitting rule.
[0025] For the sake of convenience of description, in this embodiment, the first network is a 5G network, the second network is a 4G network, correspondingly, the convergence network element is PGW-C (PDN Gate Way Control) / SMF (Session Management Function), and the traffic splitting rule is the ULCL traffic splitting rule, and specific examples are given below.
[0026] Among them, the network element PGW-C is used for traffic management in the 4G network, the network element SMF is used for session management in the 5G network, and the network element SMF selects the target UPF (User Plane Function) based on the ULCL traffic splitting rule, and thus performs traffic management on the split traffic based on the target UPF (user plane network element).
[0027] Specifically, determine whether there is an ULCL splitting rule for the target UPF in the non-direct tunnel. The non-direct tunnel is a downlink data transmission tunnel established between the user terminal and the network-side device based on the target UPF during the process of the user terminal switching from the 5G network to the 4G network. The target UPF performs traffic splitting and management on the traffic related to the user terminal based on the ULCL splitting rule.
[0028] Specifically, as Figure 2 shown, the system architecture of the 5G network includes: UE (User Equipment), (R)AN ((Radio) Access Network), AMF (Access and Mobility Management Function), SMF, ULCL, PSA (PDU Session Anchor).
[0029] As Figure 2 shown, the system architecture of the 4G network includes: SGWC (Serving Gate Way Control), MME (Mobility Management Entity), eNB (Evolved NodeB), SGWU (Serving Gate Way UPF), PGWC (PDN Gate Way Control).
[0030] The ULCL (UpLink Classifier) splitting scheme is that the network element PCF (Policy Control Function) in the 5G core network issues the ULCL splitting rule to the network element SMF according to the splitting service subscribed by the user terminal (for example, the 5G splitting package). The network element SMF selects the target UPF (such as Figure 2 the UPF1 shown) based on the ULCL splitting rule, and thus performs splitting traffic management based on the target UPF.
[0031] When the user terminal switches the network from 5G to 4G, if there is no direct tunnel between the 5G base station and the 4G base station, in order to ensure the continuity of data transmission during the network switching process, it is necessary to establish a non-direct tunnel for traffic transmission during the switching process. Specifically, a non-direct tunnel is established based on the above-mentioned target UPF as an intermediate node.
[0032] As Figure 3As shown in the figure, if the user terminal subscribes to the traffic splitting service, before the user terminal starts to switch to the 5G network, the uplink traffic of the user terminal passes through the network element (R)AN, UPF1 (UPF1 performs traffic splitting management), and reaches DN1 (data network 1) or passes through UPF2 to reach DN2. During the process of the user terminal switching the network from 5G to 4G, since the downlink data link of 4G has not been fully established successfully at this time and the 5G network has been disconnected, UPF2 has not received the address of UPF3 yet, that is, UPF2 only has the address of UPF1, and the downlink traffic of DN2 can only be transmitted to the user terminal through the non-direct transfer tunnel. At the same time, the downlink traffic of DN1 can also only be transmitted to the user terminal through the non-direct transfer tunnel.
[0033] That is to say, the non-direct transfer tunnel is a downlink data transmission tunnel established between the user terminal and the network-side device based on the target UPF during the process of the user terminal switching the 5G network to the 4G network. As Figure 3 shown in the figure, the non-direct transfer tunnel is DN1-UPF1-AN-UPF1-UPF3-eNB-UE, or DN2-UPF2-UPF1-AN-UPF1-UPF3-eNB-UE; among them, the network-side device DN1 can be a local area network such as a campus network, an Internet of Things network, or an enterprise network, and the network-side device DN2 can be a public network.
[0034] It can be understood that the above non-direct transfer tunnel is established with the above target UPF (UPF1) as an intermediate node. Before the user terminal successfully switches the network from 5G to 4G, when the downlink traffic passes through the target UPF, the target UPF performs traffic splitting management and counts the traffic at this time into the 5G traffic splitting traffic. When the downlink traffic passing through the target UPF is reported to UPF3, since UPF3 does not support the ULCL traffic splitting scheme, UPF3 will issue a 4G call record containing the traffic splitting service, which does not match the actual 4G service expectation.
[0035] Moreover, during the process of the user terminal switching the network from 5G to 4G, theoretically the user terminal cannot access DN1, but during this period, the downlink traffic of DN1 appears in the 4G call record, and the user terminal can see the content related to DN1 that it accessed before switching the network from 5G to 4G.
[0036] Furthermore, before the user terminal successfully switches the network from 5G to 4G, all traffic transmissions during this process have to pass through UPF1, and UPF1 is notified to issue a call record. This target UPF not only has a cross-impact on the management of 4G traffic, but also increases the management cost of the convergence network element PGW-C / SMF for managing the target UPF.
[0037] Therefore, after the non-direct transmission tunnel is constructed, it is necessary to determine whether there is a ULCL traffic splitting rule in the target UPF in the non-direct transmission tunnel. If there is no ULCL traffic splitting rule, the target UPF will not have a cross-impact on the management of 4G traffic, that is, there is no need to perform further processing on the target UPF.
[0038] Specifically, before the step of determining whether there is a ULCL traffic splitting rule in the target UPF in the non-direct transmission tunnel after the non-direct transmission tunnel is constructed, when a session update message is received, it is determined that the non-direct transmission tunnel is constructed.
[0039] It should be noted that the session update message is sent by the SGWC to the local when the user terminal triggers a session update; the triggering timing of the session update is the handover preparation stage when the user terminal completes the handover from the 5G network to the 4G network.
[0040] Specifically, as Figure 4 shown in steps 301-305, before constructing the non-direct transmission tunnel, the user terminal uses the 5G network, and the network element PCF distributes the ULCL traffic splitting rule to the network element SMF according to the traffic splitting service subscribed by the user terminal. The network element SMF selects the target UPF based on the ULCL traffic splitting rule, so as to perform traffic splitting management based on the target UPF; when the user terminal enters the network handover preparation stage, the network element SMF applies for 4G network-related resources, and the user terminal accesses the 4G network element to establish SGW (Serving Gate Way) - related resources.
[0041] To ensure the continuity of data transmission during the network handover process, it is necessary to establish a non-direct transmission tunnel to transmit the traffic during the handover process, and the downlink traffic can reach the user terminal through the non-direct transmission tunnel.
[0042] Further, as Figure 4 shown in step 306, after the non-direct transmission tunnel is constructed, the user terminal enters the network handover completion stage and triggers a session update. When the PGWC receives the session update message from the SGWC, it indicates that the user terminal has successfully switched the network from 5G to 4G.
[0043] S20: If it exists, send an update command to the user plane network element, and the update command is used to instruct the user plane network element to remove the network - side related attribute information by executing the update command.
[0044] After determining that there is a traffic splitting rule in the user plane network element in the non-direct transmission tunnel, it is necessary to remove the network - side related attribute information of the user plane network element so that the user plane network element will not perform traffic splitting management. Specifically, the network - side related attribute information can be the address (IP address or MAC address) of the network - side device, or the related attribute information of the network - side device such as the name of the network - side device.
[0045] It can be understood that after removing the network - side related attribute information of the user - plane network element, the user - plane network element cannot send the traffic to the corresponding network - side device, resulting in the user - plane network element being unable to perform traffic splitting management, and thus not having a cross - impact on the traffic management of the second network.
[0046] For example, after determining that the target UPF in the non - direct - transfer tunnel has a ULCL splitting rule, it is necessary to remove the network - side related attribute information of the target UPF so that the target UPF does not perform traffic splitting management; specifically, after removing the network - side related attribute information of the target UPF, the target UPF can receive uplink traffic and forward it to UPF1. However, due to the lack of network - side related attribute information, the target UPF cannot forward the uplink traffic to DN1, and the target UPF cannot receive the downlink traffic of DN1 either, or the target UPF can only receive the downlink traffic of UPF2, etc.
[0047] Furthermore, the specific implementation manner of removing the network - side related attribute information of the user - plane network element can be: sending an update command to the user - plane network element, and the user - plane network element executes the update command to remove the network - side related attribute information.
[0048] Furthermore, the update command includes a command to uninstall the splitting rule, or a command to delete the address of the network - side device, etc.
[0049] Since directly uninstalling the splitting rule can specifically avoid the target UPF from managing the split traffic without affecting normal traffic transmission, in this embodiment, the update command is preferably the command to uninstall the splitting rule.
[0050] For example, as Figure 4 shown in step 308, the target UPF executes the command to uninstall the ULCL splitting rule, deletes the PDR (Packet Detection Rule) associated with the ULCL splitting rule, and changes the target UPF attribute to IUPF (Intermediate UPF), that is, the target UPF only has user - side related attributes and does not have network - side related attributes.
[0051] In this embodiment, during the process of the user terminal switching from the first network to the second network, after determining that there is a traffic splitting rule among the user plane network elements of the non-direct transfer tunnel established based on the user plane network element in the first network, the convergence network element sends an update command to the user plane network element. By executing the update command, the user plane network element removes the network-side related attribute information, that is, when the user plane network element receives traffic, due to the absence of network-side related attribute information, the user plane network element will not perform traffic splitting management on it, and thus will not have a cross-impact on the traffic management of the second network, thereby reducing the management cost of the convergence network element for this user plane network element.
[0052] Further, based on the first embodiment, a second embodiment of traffic splitting and management of the present application is proposed. In this embodiment, step S10 includes:
[0053] A1: Based on the preset identification field corresponding to the traffic splitting rule, determine whether the traffic splitting rule exists in the user plane network element.
[0054] Since different traffic splitting rules correspond to different identification fields. For example, the traffic splitting rule includes the ULCL traffic splitting rule, and the preset identification field corresponding to the ULCL traffic splitting rule includes one of the preset data network access identifier (Data Network Access Identifier, DNAI) and the APP ID (application program identifier).
[0055] Specifically, since it is necessary to pre-configure the association relationship between the APP ID and the ULCL traffic splitting rule in the SMF and check it during the identification process, the efficiency is relatively low. In this embodiment, it is preferred to identify the ULCL traffic splitting rule through the preset data network access identifier.
[0056] Since the control plane network element adds different identifiers to each control policy when sending control policies to the user plane network element, when determining whether the traffic splitting rule exists in the user plane network element, the identifier can be identified based on the preset identification field of the traffic splitting rule.
[0057] For example, when the network element PCF in the 5G network sends control policies to the target UPF, different identifiers are added to each control policy. When determining whether the ULCL traffic splitting rule exists in the target UPF, the identifier can be identified based on the preset identification field of the ULCL traffic splitting rule.
[0058] As Figure 4 shown in step 307, since the preset data network access identifier is used to identify the DN instance (DN1 or DN2) corresponding to the traffic, the ULCL traffic splitting rule can be more accurately determined by identifying the preset data network access identifier.
[0059] In this embodiment, based on the preset identification fields of the shunting rules, the shunting rules can be identified relatively accurately, and the shunting rules can be quickly unloaded to reduce the impact of the user plane network element on the traffic management of the second network and the management cost of the convergence network element for the user plane network element, thereby improving the utilization rate of the user plane network element (using it as an intermediate node of the non-direct transmission tunnel without affecting the overall traffic transmission and management).
[0060] Based on the first embodiment and the second embodiment, a third embodiment of the shunting traffic management of the present application is proposed. In this embodiment, after the step S20, the method further includes:
[0061] B1: If an update result indicating successful update sent by the user plane network element is received, a shunting traffic bill is generated based on the call detail information reported by the user plane network element to the local side.
[0062] It should be noted that after the user plane network element removes the network-side related attribute information (unloads the shunting rules) based on the update command and then feeds back the update result to the user plane network element, if the update result is successful, it means that the user plane network element does not have network-side related attributes, that is, the user plane network element will not affect the management of the traffic of the second network. At this time, the shunting traffic accumulated by the user plane network element can be settled.
[0063] Furthermore, the convergence network element generates a shunting traffic bill based on the call detail information reported by the user plane network element; the call detail information includes the shunting traffic information of the first network traffic accumulated by the user plane network element.
[0064] It can be understood that the shunting traffic will only appear in this shunting traffic bill. After receiving the update result indicating successful update and generating the shunting traffic bill, the user plane network element will no longer perform shunting traffic management, and then the shunting traffic information of the first network traffic will not appear in the traffic bill of the second network subsequently.
[0065] For example Figure 4 In step 309 shown, after the target UPF removes the network-side related attribute information (unloads the ULCL shunting rule) based on the update command and then feeds back the update result to the target UPF, if the update result is successful, it means that the target UPF does not have network-side related attributes, that is, the target UPF will not affect the management of 4G traffic. At this time, the shunting traffic accumulated by the target UPF can be settled.
[0066] Specifically, as Figure 4 In step 310 shown, the convergence network element PGW-C / SMF generates a shunting traffic bill based on the call detail information reported by the target UPF; wherein, the call detail information includes the shunting traffic information of the 5G traffic accumulated by the target UPF.
[0067] It can be understood that the split flow rate will only appear in the split flow rate call record. After receiving the update result of successful update and generating the split flow rate call record, the target UPF will no longer perform split flow rate management, and the split flow rate information of 5G traffic will not appear in the subsequent 4G traffic call records.
[0068] Specifically, after generating the split flow rate call record, the user terminal successfully switches from the first network to the second network.
[0069] Such as Figure 4 In step 311 shown in the figure, after generating the split flow rate call record, the user terminal successfully switches to the 4G network.
[0070] In this embodiment, after the user plane network element removes the network side related attribute information based on the update command, the convergence network element generates a split flow rate call record based on the call record information reported by the user plane network element to the local side, which can separately calculate the split flow rate of the first network and the traffic of the second network without affecting the call record billing of the user.
[0071] Refer to Figure 5 , Figure 5 It is a schematic structural diagram of a device for the hardware operating environment involved in the solution of the embodiment of the present application.
[0072] Such as Figure 5 As shown in the figure, the device may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory 1005 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the foregoing processor 1001.
[0073] Those skilled in the art can understand that Figure 5 the structure shown in the figure does not constitute a limitation on the device, and it may include more or fewer components than shown in the figure, or combine some components, or arrange different components.
[0074] Such as Figure 5 As shown in the figure, the memory 1005, as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a split flow rate management program.
[0075] In Figure 5 the device shown, the network interface 1004 is mainly used for data communication with an external network; the user interface 1003 is mainly used for receiving input instructions from a user; the device calls, via the processor 1001, a shunt traffic management program stored in the memory 1005 and performs the following operations:
[0076] Determine whether there is a shunt rule in the user plane network element of the non-direct tunnel;
[0077] wherein, the non-direct tunnel is established based on the user plane network element in the first network during the process of a user terminal switching from a first network to a second network;
[0078] If there is, send an update command to the user plane network element, and the update command is used to instruct the user plane network element to remove network-side related attribute information by executing the update command.
[0079] Further, the update command includes a command to uninstall the shunt rule.
[0080] Further, the processor 1001 can call the shunt traffic management program stored in the memory 1005 and also perform the following operations:
[0081] Based on a preset identification field corresponding to the shunt rule, determine whether the shunt rule exists in the user plane network element.
[0082] Further, the shunt rule includes a ULCL shunt rule, and the preset identification field corresponding to the ULCL shunt rule includes a preset data network access identifier.
[0083] Further, the processor 1001 can call the shunt traffic management program stored in the memory 1005 and also perform the following operations:
[0084] If an update result indicating successful update sent by the user plane network element is received, generate a shunt traffic bill based on the call detail information reported by the user plane network element to the local side.
[0085] Further, the call detail information includes shunt traffic information of the first network traffic cumulatively managed by the user plane network element.
[0086] Further, after the shunt traffic bill is generated, the user terminal successfully switches from the first network to the second network.
[0087] Further, the convergence network element includes a PGW-C / SMF, the first network includes a 5G network, and the second network includes a 4G network.
[0088] In this embodiment, during the process of the user terminal switching from the first network to the second network, after determining that there is a traffic splitting rule in the user plane network element of the non-direct transfer tunnel established based on the user plane network element in the first network, an update command is sent to the user plane network element. By executing the update command, the user plane network element removes the network-side related attribute information, that is, when the user plane network element receives traffic, due to the absence of network-side related attribute information, the user plane network element will not perform traffic splitting management on it, and thus will not have a cross impact on the traffic management of the second network, thereby reducing the management cost of the convergence network element for this user plane network element.
[0089] It should be noted that the above traffic splitting and flow management device can also implement each step in the above method and achieve the corresponding technical effects, which will not be elaborated in this embodiment.
[0090] In addition, an embodiment of the present application also proposes a computer-readable storage medium, on which a traffic splitting and flow management program is stored. When the traffic splitting and flow management program is executed by a processor, the following operations are implemented:
[0091] Determine whether there is a traffic splitting rule in the user plane network element of the non-direct transfer tunnel;
[0092] Wherein, the non-direct transfer tunnel is established based on the user plane network element in the first network during the process of the user terminal switching from the first network to the second network;
[0093] If there is, send an update command to the user plane network element, and the update command is used to instruct the user plane network element to remove the network-side related attribute information by executing the update command.
[0094] In this embodiment, during the process of the user terminal switching from the first network to the second network, after determining that there is a traffic splitting rule in the user plane network element of the non-direct transfer tunnel established based on the user plane network element in the first network, an update command is sent to the user plane network element. By executing the update command, the user plane network element removes the network-side related attribute information, that is, when the user plane network element receives traffic, due to the absence of network-side related attribute information, the user plane network element will not perform traffic splitting management on it, and thus will not have a cross impact on the traffic management of the second network, thereby reducing the management cost of the convergence network element for this user plane network element.
[0095] It should be noted that when the above computer-readable storage medium is executed by a processor, it can also implement each step in the above method and achieve the corresponding technical effects, which will not be elaborated in this embodiment.
