Description

Technical Field

[0001] The present application relates to the field of XR business technology, and specifically to a business offloading method, apparatus, computer equipment and storage medium. Background Art

[0002] XR (Extended Reality) business refers to the business generated based on XR technology. XR technology refers to a combination of real and virtual, human-computer interactive environment generated by computer technology and wearable devices. XR technology integrates multiple forms such as augmented reality (AR), virtual reality (VR), and mixed reality (MR). It uses opaque head-mounted devices or other related devices to simulate a virtual world, provide users with visual, auditory and other sensory simulations, and create a strong sense of "immersion" and "presence".

[0003] With the rapid development of the fifth generation of mobile communication technology 5G network and the deployment of the sixth generation of mobile communication technology 6G network in the future, the application prospects of XR technology will become more and more broad. In order to fully guarantee the service experience of users in various scenarios, especially at home or in public places with poor mobile network coverage, it is particularly important to support users to enjoy XR services through untrusted WLAN (Wireless Local Area Network) access. The current network architecture and signaling process support XR services to establish a connection with the XR server through untrusted WLAN access via N3IWF (Non-3GPP InterWorking Function) network elements and 5GC (5G Core) network. Since different XR services have significant differences in latency sensitivity and bandwidth requirements, operators and XR service providers need to configure strategies more flexibly. For some XR services with particularly high latency requirements or particularly large bandwidth requirements, they can be diverted to the local XR platform for processing to reduce transmission delays and improve processing efficiency.

[0004] However, in the current network architecture, XR terminals discover N3IWF based on pre-configured addresses and cannot be flexibly modified after access. Therefore, when processing XR services, it is impossible to divert XR services to the local XR server, resulting in poor service quality of XR services. Summary of the invention

[0068] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0069] The service diversion method provided in the embodiment of the present application is mainly applied to Figure 1 In the application environment shown, that is, the diversion processing of XR services in the untrusted WLAN access scenario. Among them, the XRAF network element located in the central area obtains the service performance of each XR service when it detects that the central XR server receives the service data stream of at least two XR services of the XR terminal in the local area through the 5G core network and the central N3IWF network element. And according to the service performance of each XR service, determine the first XR service that meets the local service diversion conditions among the XR services. The XRAF network element in the central area sends a service diversion request to the 5G core network; wherein the service diversion request is used to instruct the 5G core network to send a first redirection indication to the central N3IWF network element, the first redirection indication is used to instruct the central N3IWF network element to send a second redirection indication to the XR terminal, and the second redirection indication is used to instruct the XR terminal to send the service data stream of each XR service to the local N3IWF network element, so that the local N3IWF network element diverts the service data stream of the first XR service to the local XR server for processing.

[0070] The central area generally refers to the geographical location of the data center or cloud computing infrastructure. The central area is responsible for handling high-load computing tasks, such as complex 3D rendering, real-time data analysis, artificial intelligence processing, etc. The local area refers to the area whose management scope covers the location of the XR terminal. The local area contains computing nodes closer to the XR terminal. The local area can provide faster response time and lower latency.

[0071] XR (Extended Reality) AF (Application Function) network element refers to the AF network element responsible for XR business. The AF network element is similar to an application server, which interacts with other 5G core network control plane NFs and provides business services. AF network elements can exist for different application services and can be owned by operators or trusted third parties.

[0072] The central XR server refers to the XR server located in the central area, and the local XR server refers to the XR server located in the local area. The central XR server generally has stronger computing power and can handle high-load computing tasks. Compared with the central XR server, the local XR server has relatively weaker computing power and can mostly only handle some lightweight data processing tasks, but it can provide faster response time and lower latency for some XR services.

[0073] 5G Core Network (5GC) refers to the core part that supports 5G network connection, services and data transmission. It is a key component in the 5G network architecture and is responsible for handling all key functions between user equipment (UE) and the network. The 5G core network includes multiple network elements, such as UPF network element, AMF network element, SMF network element and PCF network element.

[0074] The UPF (User Port Function) network element is used to adapt specific UNI requirements to core functions and system management functions. The user port functions mainly include: A / D conversion; signaling conversion; termination of UNI functions; activation / deactivation of UNI; processing of UNI load paths / carrying capacity; and testing, maintenance, management, and control functions of UNI.

[0075] The AMF (Access and Mobility Management Function) network element is responsible for UE identity authentication, authorization, registration, mobility management, and connection management. Compared with 4G EPC, the functions of AMF are similar to MME.

[0076] The SMF (Service Management Function) network element is mainly responsible for policy control, data routing, session management, and user data management.

[0077] The PCF (Policy Control Function) network element supports a unified policy framework to manage network behavior, provides policy rules to network entities for implementation, and accesses subscription information in a unified data warehouse.

[0078] The central N3IWF (Non-3GPP InterWorking Function) network element refers to the N3IWF network element in the central area, and the local N3IWF network element refers to the N3IWF network element in the local area. The N3IWF network element is responsible for connecting untrusted non-3GPP access networks (for example, Figure 1 The untrusted WLAN (Wireless Local Area Network, Wireless LAN, WLAN) is a local area network using wireless connection) is connected to the 5G core network.

[0079] In one embodiment, Figure 2 is a flow chart of a business diversion method provided according to an embodiment of the present application, in which the method is applied to Figure 1 Taking the XR AF network element in as an example, the method includes the following steps:

[0080] S201, when it is detected that the central XR server receives the service data streams of at least two XR services of the XR terminal through the 5G core network and the central N3IWF network element, obtain the service performance of each XR service.

[0081] Among them, XR business refers to the business requested by the XR terminal, such as object tracking, map optimization, etc. Business data flow refers to the session data flow between the XR terminal and the XR server. Business performance refers to the session business performance of each XR business, such as response time, service quality, latency, etc. This application is mainly used in scenarios where the same XR terminal generates more than two XR businesses. XR terminal refers to a terminal device used to experience Extended Reality (XR) technology.

[0082] As an optional implementation of the embodiment of the present application, the XR AR network element obtains the service performance of each XR service through a detection device.

[0083] As another optional implementation of the embodiment of the present application, the XR AR network element establishes communication with the central XR server to obtain the service performance of each XR service.

[0084] It should be noted that each time an XR terminal requests an XR service, it needs to establish an XR service connection with the XR AF network element. If the XR terminal requests two XR services, it needs to establish two service connections with the XR AF network element. The service connection is an application-level connection. The service connection will only be interrupted after the XR service is interrupted. Service diversion will not cause the interruption of the service connection. The XR server is mainly used to process the service session data flow generated at the service level and to provide data processing services.

[0085] S202: Determine, according to service performances of the XR services, a first XR service that meets a local service offloading condition among the XR services.

[0086] The local business diversion condition refers to the condition for determining whether local business diversion can be performed.

[0087] As an optional implementation of the embodiment of the present application, in this embodiment, the local service diversion condition is a delay threshold, and the service delay of each XR service is determined according to the service performance of each XR service. According to the relationship between the service delay of each XR service and the delay threshold, the first XR service that meets the local service diversion condition among the XR services is determined. For example, if the service delay is greater than the delay threshold, the XR service corresponding to the service delay is the first XR service that meets the local service diversion condition. Otherwise, it is the second XR service that does not meet the local service diversion condition.

[0088] As another optional implementation of the embodiment of the present application, in this embodiment, the local business diversion condition is a score threshold, and the business score of each XR business is determined according to the business performance of each XR business. According to the relationship between the business score of each XR business and the score threshold, the first XR business that meets the local business diversion condition in each XR business is determined. For example, if the business score is less than the score threshold, the XR business corresponding to the business score is the first XR business that meets the local business diversion condition. On the contrary, it is the second XR business that does not meet the local business diversion condition. Among them, the business score can be determined based on the performance indicators in the business performance. Performance indicators include but are not limited to response time, processing time, latency, quality of service, etc.

[0089] S203, sending a service offload request to the 5G core network.

[0090] Among them, the service diversion request is used to instruct the 5G core network to send a first redirection indication to the central N3IWF network element, the first redirection indication is used to instruct the central N3IWF network element to send a second redirection indication to the XR terminal, and the second redirection indication is used to instruct the XR terminal to send the service data stream of each XR service to the local N3IWF network element, so that the local N3IWF network element diverts the service data stream of the first XR service to the local XR server for processing. The service diversion request refers to a message requesting that the service data stream of the first XR service be diverted to the local XR server in the local area to which the XR terminal belongs. The first redirection indication refers to an indication message issued by the 5G core network to instruct the central N3IWF network element to perform a redirection operation and forward session information. The second redirection indication refers to an indication message issued by the central N3IWF network element to instruct the XR terminal to perform a redirection operation. The central N3IWF network element refers to the N3IWF network element in the central area, and the local N3IWF network element refers to the N3IWF network element in the local area. The N3IWF network element is responsible for connecting untrusted non-3GPP access networks (e.g. Figure 1 Untrusted WLAN in the network is connected to the 5G core network.

[0091] Optionally, in this embodiment, a service diversion request is sent to the relevant network element devices of the 5G core network. The service diversion request is used to instruct the relevant network element devices of the 5G core network to send a first redirection instruction to the central N3IWF network element, and the first redirection instruction is used to instruct the central N3IWF network element to send a second redirection instruction to the XR terminal, and the second redirection instruction is used to instruct the XR terminal to send the service data flow of each XR service to the local N3IWF network element, so that the local N3IWF network element diverts the service data flow of the first XR service to the local XR server for processing. Relevant network element devices include but are not limited to UPF network elements, AMF network elements, SMF network elements, and PCF network elements.

[0092] Optionally, in this embodiment, when the business data flow of the first XR service is diverted, the local N3IWF network element will perform data flow analysis after receiving the business data flow, and divert the business data flow of the first XR service to the local UPF network element. The local UPR network element then sends the business data flow of the first XR service to the local XR server for processing.

[0093] The above-mentioned service diversion method, upon detecting that the central XR server receives the service data streams of at least two XR services of the XR terminal through the 5G core network and the central N3IWF network element, obtains the service performance of each XR service; determines the first XR service among each XR service that meets the local service diversion conditions according to the service performance of each XR service; and sends a service diversion request to the 5G core network; wherein the service diversion request is used to instruct the 5G core network to send a first redirection indication to the central N3IWF network element, the first redirection indication is used to instruct the central N3IWF network element to send a second redirection indication to the XR terminal, and the second redirection indication is used to instruct the XR terminal to send the service data stream of each XR service to the local N3IWF network element, so that the local N3IWF network element diverts the service data stream of the first XR service to the local XR server for processing. The XR AF network element of this application can obtain the service performance of each XR service. After determining that there is a first XR service that meets the local service diversion conditions, based on the 5G core network, the local N3IWF network element, the central N3IWF network element, and the first redirection indication and the second redirection indication, the service data flow of the first XR service is diverted to the local XR server for processing. Not only does it realize the flexible diversion of XR services, but it also effectively improves the service quality of XR services and the service experience of users.

[0094] On the basis of the above embodiment, in order to realize the normal transmission of the service data stream of the second XR service, as shown in FIG. Figure 3 As shown, an optional implementation of a service offloading method includes:

[0095] S301 : Determine, according to service performance of each XR service, a second XR service that does not meet a local service offloading condition among the XR services.

[0096] Among them, the service data flow of the second XR service is forwarded by the local N3IWF network element through the central N3IWF network element and the 5G core network to the central XR server for processing. The second XR service also refers to all XR services of the XR terminal except the first XR service.

[0097] As an optional implementation of the embodiment of the present application, in this embodiment, the local service diversion condition is a delay threshold, and the service delay of each XR service is determined according to the service performance of each XR service. For each XR service, if the service delay is not greater than the delay threshold, it is determined that the XR service does not meet the local service diversion condition, and the XR service is used as the second XR service.

[0098] As another optional implementation of the embodiment of the present application, in this embodiment, the local service diversion condition is a score threshold, and the service score of each XR service is determined according to the service performance of each XR service. For each XR service, if the service score is not less than the score threshold, it is determined that the XR service does not meet the local service diversion condition, and the XR service is used as the second XR service. Among them, the service score can be determined based on the performance indicators in the service performance. Performance indicators include but are not limited to response time, processing time, latency, quality of service, etc.

[0099] In this embodiment, based on the service performance of each XR service, a second XR service that does not meet the local service diversion conditions is determined in each XR service. The service data flow of the second XR service is forwarded by the local N3IWF network element through the central N3IWF network element and the 5G core network to the central XR server for processing. The XR terminal is redirected to the local N3IWF network element, and the service data flow of the second XR service is forwarded based on the local N3IWF network element, and forwarded to the central XR server for processing through the central N3IWF network element and the 5G core network, thereby realizing flexible forwarding of the service data flow of the second XR service, effectively avoiding the service service of the second XR service, and at the same time, due to the diversion of the first XR service, the service quality of the second XR service will also be improved.

[0100] In one of the embodiments, the service diversion request carries service attribute information of the first XR service. On this basis, the service diversion request is also used to instruct the 5G core network to determine whether to perform service diversion based on the service judgment strategy, policy indicators and service attribute information of the first XR service, and send a first redirection indication to the central N3IWF network element if it is determined to perform service diversion.

[0101] Specifically, the service diversion request is also used to instruct the PCF network element of the 5G core network to determine whether to perform service diversion based on the service judgment policy, policy indicators and service attribute information of the first XR service, and when it is determined to perform service diversion, send the diversion policy to the service management function SMF network element, so that the SMF network element sends the first redirection indication to the central N3IWF network element based on the diversion policy and the AMF network element.

[0102] Among them, the policy indicators include network resource conditions, and at least one of the access status and terminal location of the XR terminal. The service judgment strategy refers to a judgment strategy for further judging whether the first XR service needs to be diverted. The service attribute information refers to the attribute information of the first XR service, such as service type, service identifier, service demand, etc.

[0103] Optionally, in this embodiment, the PCF network element determines whether to perform service diversion based on the service judgment policy, policy indicators and service attribute information of the first XR service. An optional implementation method is to use the policy indicators and the service attribute information of the first XR service as input parameters of the service judgment policy, and the service judgment policy is combined with the input parameters to determine whether to perform service diversion.

[0104] Optionally, if service offloading is not performed, a response message indicating that service offloading is not performed is fed back to the XR AF network element.

[0105] In this embodiment, on the basis of the XR AF network element combining the service performance judgment to perform service diversion, the PCF network element of the 5G core network determines whether to perform service diversion based on the service judgment strategy, policy indicators and service attribute information of the first XR service, and sends the diversion strategy to the service management function SMF network element when it is determined to perform service diversion, so that the SMF network element sends the first redirection indication to the central N3IWF network element based on the diversion strategy and the AMF network element. In this embodiment, the judgment of service diversion of the PCF network element is added to judge whether the first XR service meets the conditions for service diversion from the network level, further improving the reliability of service diversion.

[0106] In one of the embodiments, the first redirection indication includes the terminal session information of the XR terminal and the network element address of the local N3IWF network element; the second redirection indication carries the network element address of the local N3IWF network element;

[0107] Optionally, the first redirection indication in this embodiment is also used to instruct the central N3IWF network element to send the terminal session information of the XR terminal to the local N3IWF network element. The terminal session information refers to the session information when the XR terminal establishes a PUD session with the 5G core network. It should be noted that when the XR terminal initiates an XR service request for the first time, the 5G core network needs to authenticate and establish a PDU session. Subsequent XR service requests do not need to be authenticated again, and the PDU session does not need to be established again.

[0108] Optionally, the terminal session information may also include the service attribute information of the first XR service of the XR terminal and the service attribute information of the second XR service, so that after receiving the service data stream of the XR terminal, the local N3IWF network element analyzes based on the service attribute information to determine whether the service data stream is the service data stream of the first XR service or the service data stream of the second XR service. If it is the service data stream of the first XR service, it is diverted to the local UPF network element, and the local UPF network element sends the service data stream of the first XR service to the local XR server. If it is the service data stream of the second XR service, it is forwarded to the core N3IWF network element, and the core N3IWF network element sends it to the central UPF network element of the 5G core network, and the central PF network element sends the service data stream of the second XR service to the central XR server.

[0109] Optionally, the second redirection indication is also used to instruct the XR terminal to initiate an authentication request to the 5G core network through the local N3IWF network element, and after the 5G core network authenticates the XR terminal and instructs the central N3IWF network element to disconnect from the XR terminal, the service data stream of each XR service is sent to the local N3IWF network element. It should be noted that since the XR terminal can only establish a connection with one N3IWF network element, after redirecting to the local N3IWF network element, it is necessary to perform the authentication process, and after the authentication is passed, the 5G core network control center N3IWF network element disconnects from the XR terminal, and the XR terminal can send the service data stream of each XR service to the local N3IWF network element.

[0110] It should be noted that the 5G core network's authentication of XR terminals refers to the authentication of the identity of the XR terminals. The authentication process needs to be performed by relevant network elements in the 5G core network, such as AMF network elements, SMF network elements, etc.

[0111] In this embodiment, the first redirection indication includes the terminal session information of the XR terminal and the network element address of the local N3IWF network element; the second redirection indication carries the network element address of the local N3IWF network element; the first redirection indication is also used to instruct the central N3IWF network element to send the terminal session information of the XR terminal to the local N3IWF network element. The second redirection indication is also used to instruct the XR terminal to initiate an authentication request to the 5G core network through the local N3IWF network element, and after the 5G core network authenticates the XR terminal and instructs the central N3IWF network element to disconnect from the XR terminal, the service data stream of each XR service is sent to the local N3IWF network element. Based on this embodiment, the redirection operation of the XR terminal is implemented, and the forwarding and diversion operations of the service data stream of each XR service are implemented, which improves the flexibility and service quality of XR service services.

[0115] As an optional implementation of the embodiment of the present application, a service diversion request directly sent by the XR AF network element is received.

[0116] Another optional implementation of the embodiment of the present application is to receive a service offload request indirectly sent by the XR AF network element through other devices or network elements.

[0120] As another optional implementation of the embodiment of the present application, after receiving the service diversion request, it is determined whether service diversion needs to be performed. If it is performed, a diversion strategy is sent to other network elements of the 5G core network, so that other network elements of the 5G core network send a first redirection indication to the central N3IWF network element based on the diversion strategy. It should be noted that if it is not performed, a service diversion response message indicating that no diversion is performed is sent to the XR AF network element.

[0121] In this embodiment, a service diversion request sent by the XR AF network element is received; wherein, the service diversion request is sent by the XR AF network element after determining that there is a first XR service that meets the local service diversion conditions among the XR services based on the service performance of each XR service; the service performance of each XR service is obtained by the XR AF network element when it detects that the central XR server receives the service data streams of at least two XR services of the XR terminal through the 5G core network and the central N3IWF network element. According to the service diversion request and other network elements of the 5G core network, a first redirection instruction is sent to the central N3IWF network element; wherein the first redirection instruction is used to instruct the central N3IWF network element to send a second redirection instruction to the XR terminal, and the second redirection instruction is used to instruct the XR terminal to send the service data flow of each XR service to the local N3IWF network element, so that the local N3IWF network element diverts the service data flow of the first XR service to the local XR server for processing. This application is based on other network elements and PCF network elements of the 5G core network, as well as local N3IWF network elements, central N3IWF network elements, first redirection instructions and second redirection instructions to achieve the diversion of the service data flow of the first XR service to the local XR server for processing. Not only does it achieve flexible diversion of XR services, but it also effectively improves the service quality of XR services and the user's service experience.

[0122] In one embodiment, the service offload request carries service attribute information of the first XR service; the other network elements include SMF network elements and AMF network elements. Figure 5 As shown, an optional implementation of S402 includes:

[0123] S501 : Determine whether to perform service diversion according to a service judgment strategy, a policy indicator, and service attribute information of a first XR service.

[0124] Among them, the policy indicators include network resource conditions, and at least one of the access status and terminal location of the XR terminal. The service judgment strategy refers to a judgment strategy for further judging whether the first XR service needs to be diverted. Service attribute information refers to the attribute information of the first XR service, such as service type, service identification, service demand, etc. The network resource situation refers to the network resource usage of the 5G core network.

[0125] As an optional implementation of the embodiment of the present application, the policy indicator and the service attribute information of the first XR service are used as input parameters of the service judgment policy, and the service judgment policy combines the input parameters to determine whether to perform service diversion.

The intelligent judgment model can be a neural network model.

[0127] S502, when it is determined to perform service diversion, a diversion strategy is sent to the SMF network element, so that the SMF network element sends a first redirection indication to the central N3IWF network element based on the diversion strategy and the AMF network element.

[0130] Optionally, the first redirection indication in this embodiment is also used to instruct the central N3IWF network element to send the terminal session information of the XR terminal to the local N3IWF network element. The terminal session information refers to the session information when the XR terminal establishes a PUD session with the 5G core network. It should be noted that when the XR terminal initiates an XR service request for the first time, the 5G core network needs to authenticate and establish a PDU session. Subsequent XR service requests do not need to be authenticated again, and the PDU session does not need to be established again.

[0131] Optionally, the terminal session information may also include the service attribute information of the first XR service of the XR terminal and the service attribute information of the second XR service, so that after receiving the service data stream of the XR terminal, the local N3IWF network element analyzes based on the service attribute information to determine whether the service data stream is the service data stream of the first XR service or the service data stream of the second XR service.

It should be noted that since the XR terminal can only establish a connection with one N3IWF network element, after redirecting to the local N3IWF network element, it is necessary to perform the authentication process, and after the authentication is passed, the 5G core network control center N3IWF network element disconnects from the XR terminal, and the XR terminal can send the service data stream of each XR service to the local N3IWF network element.

[0133] It should be noted that the 5G core network's authentication of XR terminals refers to the authentication of the identity of the XR terminals. The authentication process needs to be performed by relevant network elements in the 5G core network, such as AMF network elements, SMF network elements, etc.
