Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a service offloading method, system, electronic device, and computer-readable medium. Background Technology

[0002] The 3GPP standard defines the architecture and procedures for untrusted, non-3GPP access (such as Wi-Fi) to the mobile core network. In 4G, untrusted Wi-Fi accesses the 4G core network through ePDG (Evolved Packet Data Gateway); in 5G, untrusted Wi-Fi accesses the 5G core network through N3IWF (Non-3GPP Interworking Function). Based on this approach, Wi-Fi access and 3GPP access can be integrated and unified for access to the mobile core network, which is beneficial for using Wi-Fi to supplement indoor mobile signal coverage and for achieving seamless handover between VoWi-Fi (Voice over Wi-Fi) and VoLTE / VoNR.

[0003] However, for general internet services, Wi-Fi access can be directly accessed through a router (without going through the mobile core network), and for the same service bandwidth, the cost of mobile core network equipment is several times that of ordinary router equipment.

[0004] In the current standard, when a user accesses the network via Wi-Fi, the terminal does not use the User Terminal Routing Selection Policy (URSP). All of the user's services either revolve entirely through the mobile core network or bypass it entirely, which makes the deployment cost of VoWi-Fi services very high.

[0005] Therefore, a new business offloading method, system, electronic device, and computer-readable medium are needed.

[0006] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure. Summary of the Invention

[0007] In view of this, embodiments of the present disclosure provide a service offloading method, system, electronic device, and computer-readable medium that can automatically select different routes for different services, reduce the construction cost of VoWifi services, and improve the service experience.

[0035] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] Figure 1 This is a system block diagram illustrating a service diversion method and apparatus according to an exemplary embodiment.

[0037] In system 100 of the service offloading method and apparatus, the mobile core network 105 can be a server providing various services, such as a backend management server (only an example) that supports the service offloading system operated by users using terminal devices 101, 102, and 103 via network 104. Server 105 can, for example, configure user terminal routing policies in a policy control function, including a Wi-Fi-specific routing policy; receive registration messages from terminals; and issue the user terminal routing policy to the terminals; thereby enabling terminal devices 101, 102, or 103 to access the Internet via a Wi-Fi network; register in the mobile core network via a Wi-Fi network; receive the user terminal routing policy issued by the mobile core network; determine the target network in the mobile core network and other data networks based on the current service flow and the Wi-Fi-specific routing policy; and connect the service data of the current service flow to the target network.

[0038] Figure 2This is a flowchart illustrating a service offloading method according to an exemplary embodiment. The service offloading method provided in this disclosure can be executed by any electronic device with computing capabilities, such as terminal devices 101, 102, and 103. The service offloading method provided in this disclosure may include steps S202 to S210.

[0039] like Figure 2 As shown, in step S202, the internet is accessed via a Wi-Fi network.

[0040] In step S204, registration is performed on the mobile core network via the Wi-Fi network.

[0041] In step S206, the user terminal routing selection policy issued by the mobile core network is received. The user terminal routing selection policy includes a dedicated Wi-Fi routing selection policy.

[0042] In this embodiment of the disclosure, the user terminal routing policy is an extended version. This extended processing makes the user terminal routing policy include a Wi-Fi-specific routing policy.

[0043] In step S208, the target network is determined in the mobile core network and other data networks based on the current service flow and the Wi-Fi dedicated routing selection policy, wherein the other data networks may include the Internet.

[0044] In this embodiment of the disclosure, the dedicated Wi-Fi routing selection strategy may include selection strategies for other data networks and the mobile core network. For example, when the current service flow is a VoWi-Fi service, its target network can be determined to be the mobile core network.

[0045] In an exemplary embodiment, the access type validity condition can be obtained first in the Wi-Fi dedicated routing policy; when it is determined that the terminal is accessing the mobile core network from the Wi-Fi network based on the access type validity condition, the target network can be determined in the mobile core network and other data networks based on the current service flow and the Wi-Fi dedicated routing policy.

[0046] The access type validity condition describes the specific access type that must be met for this routing rule to take effect. This specific access type is, for example, access from a Wi-Fi network.

[0047] Among them, the routing of the current service flow can be determined through the professional Wi-Fi routing selection strategy, thereby determining whether the current service flow accesses the mobile core network or directly accesses the Internet through the local router.

[0048] In step S210, the service data of the current service flow is connected to the target network.

[0049] The routing strategy for the Wi-Fi-specific route can determine the route of the current service flow. Specifically, it can determine whether the current service flow accesses the mobile core network or directly accesses the Internet through a local router.

[0050] According to the service offloading method provided in this disclosure embodiment, after a terminal accesses the Internet via a Wi-Fi network and registers with the mobile core network, it can intelligently select the current service flow based on the Wi-Fi dedicated routing selection policy in the user terminal routing selection policy by receiving the user terminal routing selection policy issued by the mobile core network. This determines whether to use other data networks or the mobile core network as the target network, thereby reducing the construction cost of VoWi-Fi services, reducing latency, and improving service experience.

[0051] Figure 3 This is a flowchart illustrating a service diversion method according to another exemplary embodiment. Figure 2 Step S208 of the embodiment may further include steps S302 to S306.

[0052] like Figure 3 As shown, in step S302, the service identifier of the current service flow is determined.

[0053] In this embodiment of the disclosure, the current service flow is the service information that the terminal currently needs to access the network for.

[0054] In step S304, a target traffic descriptor matching the service identifier is determined in the Wi-Fi dedicated routing selection policy.

[0055] The dedicated Wi-Fi routing policy can include traffic descriptors and route selection descriptors. The traffic descriptor that shares the same service identifier in the dedicated Wi-Fi routing policy can be identified as the target traffic descriptor.

[0056] In step S306, the target network is determined according to the routing descriptor corresponding to the target traffic descriptor in the Wi-Fi dedicated routing policy. The routing descriptor includes other data networks or mobile core networks.

[0057] In this embodiment of the disclosure, if the routing descriptor includes other data networks, then the other data network, such as the Internet, is accessed directly via the Wi-Fi network. If the routing descriptor includes the mobile core network, then the target network is determined to be the mobile core network.

[0058] Figure 4 This is a flowchart illustrating a service offloading method according to yet another exemplary embodiment. The service offloading method provided in this disclosure may include steps S402 to S410.

[0059] like Figure 4As shown, in step S402, when accessing the Internet via a Wifi network, the first IP address assigned by the Wifi network is obtained.

[0060] In this embodiment of the disclosure, the first IP address is the IP address of the terminal assigned to the terminal by the Wi-Fi network.

[0061] In step S404, a secure tunnel is established with the first IP address and the Non-3GPP Interworking Function (N3IWF) to register in the mobile core network.

[0062] In this embodiment of the disclosure, access to the mobile core network is achieved by registering with the mobile core network.

[0063] In step S406, the second IP address allocated by the mobile core network is obtained.

[0064] In this embodiment of the disclosure, the second IP address is the IP address of the terminal assigned by the mobile core network to the terminal.

[0065] In step S408, if the target network is another data network, the first IP address is used as the source address, and the service data of the current service flow is sent to the other data network.

[0066] In step S410, if the target network is a mobile core network, the second IP address is used as the source address, and the service data of the current service flow is sent to the mobile core network through a secure tunnel.

[0067] In this embodiment of the disclosure, for example, when the current service flow is a VoWifi service, the target network can be identified as a mobile core network.

[0068] Figure 5 This is a flowchart illustrating a service offloading method according to yet another exemplary embodiment. The service offloading method provided in this disclosure may include steps S502 to S506.

[0069] like Figure 5 As shown, in step S502, the user terminal routing policy is configured in the Policy Control Function (PCF), and the user terminal routing policy includes a Wi-Fi-specific routing policy.

[0070] In step S504, a registration message from the terminal is received. The terminal registers via a Wi-Fi network and accesses the Internet via the Wi-Fi network.

[0071] In step S506, a user terminal routing policy is sent to the terminal so that the terminal can determine the target network in the mobile core network and other data networks according to the current service flow and the Wi-Fi dedicated routing policy; and the service data of the current service flow is connected to the target network, other data networks including the Internet.

[0072] Figure 6 This is a flowchart illustrating a service offloading method according to yet another exemplary embodiment. The service offloading method provided in this disclosure may include steps S602 to S608.

[0073] like Figure 6 As shown, in step S602, a dedicated Wi-Fi routing policy is added to the URSP. Specifically, a dedicated information cell is added to the URSP to store the dedicated Wi-Fi routing policy. The added information cell includes: 1) an identifier indicating whether to access the mobile core network. This information cell indicates whether a qualified service flow should access the mobile core network or directly access the data network; 2) access type validity conditions. This information cell specifies the specific access type conditions that must be met for this routing rule to take effect, such as specifying that the rule only takes effect when the terminal accesses from the Wi-Fi network.

[0074] In step S604, the terminal accesses the mobile core network from the Wi-Fi network. Specifically, the terminal accesses the Internet from the Wi-Fi network and obtains a first IP address assigned to it by the Wi-Fi network; subsequently, the terminal accesses the mobile core network through the Wi-Fi network and completes registration, obtaining a second IP address assigned to it by the mobile network.

[0075] In step S606, the terminal obtains and applies the URSP. Specifically, the mobile core network distributes the user's URSP to the terminal, and the terminal installs and applies the received URSP.

[0076] In step S608, the terminal performs intelligent routing of services according to the Wi-Fi dedicated routing policy. When the terminal conducts services under Wi-Fi, it needs to select a route for the service according to the URSP containing the Wi-Fi dedicated routing policy. When the matched service requires access to the mobile core network, the terminal should transmit the corresponding service data packet (with the second IP address as the source address) to the mobile core network through the tunnel between the terminal and the interconnection gateway (ePDG / N3IWF or a gateway with similar functions); when the matched service does not require access to the mobile core network, the terminal will directly access the data network via the Wi-Fi network with the corresponding service data packet (with the first IP address as the source address).

[0077] Figure 7This is a flowchart illustrating a service offloading method according to another exemplary embodiment. This disclosure uses the example of a 5G user simultaneously using VoWifi and WeChat services via a Wifi network for illustration. The service offloading method provided in this disclosure may include steps S702 to S706.

[0078] In step S702, a dedicated Wi-Fi routing policy is added to the URSP. Specifically, an extended URSP is configured for the user in the PCF of the 5G mobile core network. This extended URSP requires that under Wi-Fi access, VoWifi services pass through the mobile core network, while other Internet services do not need to pass through the mobile core network.

[0079] In step S704, the terminal successfully accesses the Internet from the Wi-Fi network, at which point the terminal obtains the first IP address assigned by the Wi-Fi network.

[0080] In step S706, the terminal accesses the 5G mobile core network via the Wi-Fi network and obtains the user's latest URSP. Specifically, the terminal establishes a secure tunnel with the N3IWF using the first IP address and successfully registers and accesses the 5G core network. At this time, the terminal obtains a second IP address assigned by the 5G core network. The PCF then sends the user's latest URSP to the terminal.

[0081] In step S708, the terminal uses the latest URSP under Wifi network access.

[0082] In step S710, before the terminal initiates the VoWifi service, it performs a matching process according to the URSP rules and finds that the VoWifi service needs to go through the mobile core network.

[0083] In step S712, the terminal transmits the VoWifi service to the 5G mobile core network. Specifically, the terminal transmits the VoWifi service data packet (using the second IP address allocated by the mobile core network as the source address) to the mobile core network via the tunnel between the terminal (using the first IP address allocated by the Wifi network) and the N3IWF.

[0084] In step S714, before the terminal initiates the WeChat service under the Wi-Fi network, it performs matching according to the URSP rules and finds that the WeChat service does not need to go through the mobile core network.

[0085] In step S716, the terminal directly sends the WeChat service data packet (with the first IP address assigned by the Wi-Fi network as the source address) to the Internet.

[0086] To address the issue that services cannot be intelligently routed when users access the network from a Wi-Fi network, resulting in high deployment costs because all Wi-Fi service flows must pass through the mobile core network when supporting VoWi-Fi services, the service routing method provided in this disclosure allows the terminal to automatically select different routes for different services based on the extended URSP after accessing the Wi-Fi network. The terminal can choose to access the mobile core network or directly access the data network. This method significantly reduces the construction cost of VoWi-Fi services and improves the service experience (reducing latency).

[0087] It should be clearly understood that this disclosure describes how specific examples are formed and used, but the principles of this disclosure are not limited to any details of these examples. Rather, based on the teachings of this disclosure, these principles can be applied to many other embodiments.
