[0071] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0072] The service trace method provided by the embodiments of the present application can be applied in an application environment as shown in the figure. Figure 1 As shown in the figure, after the trace gateway receives the first trace request carrying the device identifier sent by the evolved packet data gateway, the trace gateway sends the second trace request carrying the device identifier to the service operation platform. Based on the device information, the trace result is determined. The trace result is sent to the evolved packet data gateway. The first trace request is sent by the evolved packet data gateway in the case that the target terminal initiates a service request through the target CPE. The device identifier is the identity identifier of the target CPE. The second trace request is used to instruct the service operation platform to determine the device information of the target CPE based on the device identifier, and send the device information to the trace gateway.

[0073] The trace gateway refers to the gateway device of the operator with the trace function (i.e. sending the trace request and the trace result).

[0074] The target terminal refers to the terminal device that initiates a service request (for example, initiates a VoWiFi service access request) on the user side. The terminal device can be a smart terminal such as a mobile phone or a computer, or a smart terminal device such as a smart watch or a smart bracelet.

[0075] The target CPE (Customer Premises Equipment) refers to the CPE connected by the target terminal. The target terminal accesses the target CPE through a WiFi (Wireless Fidelity) signal.

[0076] The service operation platform refers to the platform on the operator side for managing and operating mobile communication services. The service operation platform can be a server or a server cluster.

[0077] In one embodiment, Figure 2is a flowchart of a service traceability method according to an embodiment of the present application. The method is applied to Figure 1 a traceability gateway in the service traceability method in the embodiment of the present application. The method comprises the following steps.

[0078] S201, after receiving the first traceability request carrying the device identifier sent by the evolved packet data gateway, sending the second traceability request carrying the device identifier to the service operation platform.

[0079] The first traceability request is sent by the evolved packet data gateway when detecting that the target terminal initiates a service request through the target CPE, and the device identifier is the identity identifier of the target CPE; the second traceability request is used to instruct the service operation platform to determine the device information of the target CPE based on the device identifier, and send the device information to the traceability gateway. The identity identifier refers to a unique identifier used to represent the identity of the target CPE. The device information refers to the relevant information of the target CPE. The second traceability request refers to the traceability request sent by the traceability gateway to the service operation platform for the target terminal.

[0080] Optionally, in the embodiment, the identity identifier can be an IPv6 (Internet Protocol version 6) address of the target CPE.

[0081] Optionally, in the embodiment, the first traceability request is sent by the evolved packet data gateway (i.e., ePDG (evolved Packet Data Gateway)) when detecting that the target terminal initiates a service request for a target service through the target CPE, i.e., when requesting to provide the service corresponding to the target service. The target service can be a VoWiFi service.

[0082] Optionally, in the embodiment, the evolved packet data gateway detects that the target terminal initiates a service request through the target CPE in the following manner: the evolved packet data gateway receives a service access request (e.g., a VoWiFi service access request) initiated by the target terminal through the target CPE, specifically, a service access request initiated by the target terminal through the target CPE, a 5G access network, and a UPF (User Plane Function) network element.

[0083] Optionally, in the embodiment, the optional implementation of sending the second traceability request carrying the device identifier to the service operation platform is that, based on the device identifier, when it is determined that the terminal device pointed to by the device identifier is a CPE device, the second traceability request carrying the device identifier is sent to the service operation platform. Specifically, based on the IPv6 address, when it is determined that the device pointed to by the IPv6 address is a CPE device, the second traceability request carrying the IPv6 address is sent to the service operation platform.

[0084] Optionally, the device information in the embodiment includes at least one of IMSI information and base station identification, wherein the base station identification is the base station identification of the communication base station currently accessed by the target CPE. The base station identification can be a base station ID.

[0085] Optionally, in some embodiments, the second trace request is further used to instruct the business operation platform to query the service subscription information of the target CPE based on the device identification, and to obtain the IMSI information of the target CPE based on the service subscription information. Optionally, the service subscription information is sent by the UDM network element to the business operation platform after the target CPE subscribes to the target service (for example, VoWiFi service) from the UDM network element, and the device identification allocated to the target CPE, that is, the allocated IPv6 address, is also sent at the same time of sending the service subscription information.

[0086] Optionally, in some embodiments, the second trace request is further used to instruct the business operation platform to send a query request carrying the device identification to the UDM network element, so that the UDM network element sends the base station identification to the business operation platform. Specifically, the UDM network element queries the communication base station currently accessed by the target CPE based on the IPv6 address to other devices or locally, and feeds back the base station identification of the communication base station currently accessed to the business operation platform.

[0087] S202, determining a trace result based on the device information.

[0088] As an optional implementation of the embodiment of the application, the location information of the target CPE is queried based on the device information. The location information of the target CPE is taken as the trace result for the target terminal.

[0089] S203, sending the trace result to the evolved packet data gateway.

[0090] Optionally, the trace gateway directly or indirectly sends the trace result to the evolved packet data gateway in the embodiment, so that the evolved packet data gateway provides the service request related service for the target terminal based on the trace result. For example, if the service request is an emergency call request of VoWiFi service, the evolved packet data gateway determines the identification of the nearest access (for example, the IMSI identification of the emergency service point) of the emergency call based on the trace result, and provides the corresponding service for the target terminal based on the identification of the nearest access.

[0091] The service tracing method receives the first tracing request carrying the device identifier sent by the evolved packet data gateway, and sends a second tracing request carrying the device identifier to the service operation platform. The first tracing request is sent by the evolved packet data gateway when it detects that the target terminal initiates a service request through the target CPE. The device identifier is the identity identifier of the target CPE. The second tracing request is used to instruct the service operation platform to determine the device information of the target CPE based on the device identifier, and send the device information to the tracing gateway. Based on the device information, the tracing result is determined. The tracing result is sent to the evolved packet data gateway. The service tracing method based on the application can realize tracing in the VoWiFi service scenario, and has high tracing efficiency, improves the response speed of some specific VoWiFi services (for example, emergency call service), and thus improves user satisfaction.

[0092] In one of the embodiments, in order to more efficiently determine the tracing result, as shown in Figure 3 , the optional implementation of determining the tracing result based on the device information includes:

[0093] S301, determining the BAC-ID associated with the base station identifier based on the base station identifier.

[0094] The BAC-ID (Business Assurance Center Identifier) is a logical identifier for background user data management.

[0095] Optionally, in this embodiment, the tracing gateway obtains the BAC-ID associated with the base station identifier in the form of querying the data table based on the base station identifier and the internal data table.

[0096] S302, taking the IMSI information and the BAC-ID as the tracing result.

[0097] In this embodiment, the BAC-ID associated with the base station identifier is determined based on the base station identifier. The IMSI information and the BAC-ID are taken as the tracing result. Based on this embodiment, the tracing result can be more efficiently determined.

[0098] In one embodiment, Figure 4 is a flowchart of a service tracing method according to an embodiment of the application. The method is applied to the service operation platform in Figure 1 for example. The method includes the following steps:

[0099] S401, receiving the second tracing request carrying the device identifier sent by the tracing gateway.

[0100] The second traceability request is sent by the traceability gateway after receiving the first traceability request carrying the device identifier sent by the evolved packet data gateway; the first traceability request is sent by the evolved packet data gateway when detecting that the target terminal initiates a service request through the target CPE; and the device identifier is an identity identifier of the target CPE.

[0101] Optionally, the identity identifier in the embodiment can be an IPv6 (Internet Protocol version 6) address of the target CPE.

[0102] Optionally, the first traceability request in the embodiment is sent by the evolved packet data gateway (i.e., ePDG (evolved Packet Data Gateway)) when detecting that the target terminal initiates a service request for a target service through the target CPE, i.e., when requesting to provide a service corresponding to the target service. The target service can be a VoWiFi service.

[0103] Optionally, the evolved packet data gateway detects that the target terminal initiates a service request through the target CPE in the following manner: the evolved packet data gateway receives a service access request (for example, a VoWiFi service access request) initiated by the target terminal through the target CPE, a 5G access network and a UPF (User Plane Function) network element, specifically, receives the service access request initiated by the target terminal through the target CPE, the 5G access network and the UPF network element.

[0104] Optionally, the second traceability request in the embodiment is sent by the traceability gateway to the service operation platform when the traceability gateway determines, based on the device identifier, that the terminal device pointed to by the device identifier is a CPE device.

The method based on the present application can realize traceability in the VoWiFi service scenario, and has high traceability efficiency, improves the response speed of some specific VoWiFi services (for example, emergency call service), and thus improves the user satisfaction.

[0111] S501, querying the service subscription information of the target CPE based on the device identifier.

[0112] The service subscription information refers to the subscription information of the target service (for example, VoWiFi service) corresponding to the service request of the target CPE.

[0113] Optionally, in this embodiment, the service operation platform will pre-receive the service subscription information of the target CPE and the identity identifier allocated for the target CPE sent by the UDM network element; the service subscription information and the identity identifier are sent by the UDM network element to the service operation platform in the case of determining that the target CPE service subscription is successful. That is, the target CPE will pre-initiate a service subscription request to the UDM network element, and after the service subscription is successful, the UDM network element will allocate an IPv6 address for the target CPE. And the IPv6 address and the service subscription information are sent to the service operation platform.
