Specifically, under a 5G network architecture, the AMF network element and the SMF network element are connected through an N11 interface, information interaction is performed after a user terminal is powered on, and an electronic device serving as a data acquisition party intercepts a session message interacted between the two network elements. For example, after the user terminal is powered on, the AMF may send a Protocol Data Unit (PDU) creation message, specifically, a CreateSMContext request message, to the SMF, where the CreateSMContext request message includes user information: a Subscriber Identity, such as an International Mobile Subscriber Identity (IMSI); a user terminal Identity, such as an International Mobile Equipment Identity (IMEI); the user terminal calling number, such as MSISDN, the number which can only identify the mobile user in the public telephone network switching network number plan; and the user location, indicated by location.

Specifically, after the SMF sends the CreateSMContext response message, it also sends a transmission request message to the AMF, and the AMF also returns a transmission response message to the SMF, which is specifically represented by an N1N2MessageTransfer request/response message. Wherein, the N1N2MessageTransfer request message carries the UPF identifier corresponding to the uplink N3 interface, which may be F3The TEID representation contains IP and tunnel identifiers of UPF allocated by SMF for user terminal to get on the internet, and also carries PDU session identifier and user identity identifier. At this time, the electronic device acquires the UPF identifier corresponding to the N3 interface by collecting the transmission message: f3-TEID, PDU session identity and associating with user information according to session identity and user identity, F3The TEID is added to the first storage information to obtain the second storage information, for example, as shown in the following table 2:
TABLE 2
Figure BDA0002865593240000081
It should be noted that an update message is also sent between the AMF and the SMF, for example, the AMF sends an update request message to the SMF, which is represented by an UpdateSMContext request message, and the UpdateSMContext request message carries a session context identifier and a user information update message, for example, a location of a user included in the user information update message is updated from "location X" to "location Y". And the SMF also returns an update response message to the AMF, the update response message is represented by an UpdateSMContext response message, and the UpdateSMContext response message carries a UPF identification update message corresponding to the N3 interface. For example, the UPF id update message corresponding to the N3 interface includes F3TEID in TEID is updated from 003 to 004. At this time, the electronic device may acquire the session context identifier, the user information update message, and the UPF label corresponding to the N3 interface by collecting the update messageIdentify the update message, and update the second storage information according to the update message to obtain third storage information according to the session context identifier as an index, for example, as shown in table 3 below, a schematic diagram of the third storage information is shown:
TABLE 3
Figure BDA0002865593240000082
Figure BDA0002865593240000091
As shown in table 3, the third storage information includes the user information and the UPF identifier F corresponding to the N3 interface3-a first correspondence of TEIDs.
Step S102, acquiring a second corresponding relation between the UPF identifier corresponding to the N3 interface and the UPF identifier corresponding to the N9 interface by acquiring session messages of the SMF network element and the UPF network element in the N4 interface.
Optionally, the session message between the SMF network element and the UPF network element includes a Packet Forwarding Control Protocol (PFCP) message.
Optionally, acquiring a second correspondence between the UPF identifier corresponding to the N3 interface and the UPF identifier corresponding to the N9 interface by collecting session messages between the SMF network element and the UPF network element in the N4 interface includes: acquiring a data packet identification rule and a forwarding action rule from the PFCP message; extracting UPF identifications corresponding to the N3 interface from the data packet identification rule, and extracting UPF identifications corresponding to the N9 interface from the forwarding action rule; and associating the UPF identification corresponding to the N3 interface with the UPF identification corresponding to the N9 interface to obtain a second corresponding relation.
Specifically, under a 5G network architecture, an SMF network element and a UPF network element are connected through an N4 interface, the SMF network element and the UPF network element interact with each other, and an electronic device serving as a data acquisition party intercepts a session message interacted between the two network elements. For example, the SMF network element may send a PFCP request message to the UPF network element, where the PFCP request message includes a packet identification rule and a forwarding actionAnd (5) making a rule. Wherein, the data packet identification rule includes a UPF identifier F corresponding to the N3 interface3TEID, UPF, determining the upstream packet received contains F3TEID is identified and forwarded backwards; the forwarding rule contains UPF identification corresponding to the N9 interface, and F is used9TEID indicates that F contained in upstream packets will be forwarded3-TEID is deleted and F is9The TEID is added to the packet header of the upstream packet. And includes the IP, port number, and session identification in the PFCP message and associates with a subsequent PFCP response message based on the above information. In addition, the UPF network element returns a PFCP response message to the SMF after processing the uplink packet according to the packet identification rule and the forwarding rule. The electronic equipment can acquire the data packet identification rule and the forwarding rule by acquiring the PFCP message, and respectively acquire the F from the two rules3TEID and F9-TEID. And F is3TEID and F9The TEIDs are associated to obtain a second correspondence, which is shown in the following table 4:
TABLE 4
Figure BDA0002865593240000101
In the embodiment, the uplink F-TEID (F-TEID) of the UPF side of the N3 interface, namely F-TEID, is maintained in real time through processing the N4 interface3TEID, PSA side upstream F-TEID, interface with N9, i.e. F9-correspondence of TEIDs. Of course, SMF can also realize F by sending PFCP update message3-TEID or F9Updating the TEID, so that the electronic device may also update the second correspondence by collecting session messages of the SMF network element and the UPF network element in the N4 interface.
Step S103, obtaining user uplink data containing the UPF identification corresponding to the N9 interface and the user operation behavior, searching user information according to the UPF identification corresponding to the N9 interface, the second corresponding relation and the first corresponding relation, and performing associated backfill on the user information and the user operation behavior.

Specifically, for the user plane, after acquiring the original uplink data of the user, the UPF network element will pass through F3TEID identifies the user's original upstream data, after passing the identification, F contained in the original upstream data3-TEID is deleted, then F9TEID is added to the original upstream data to generate user upstream data and transmitted to PDU session anchor point, PSA in FIG. 1, so that F can be extracted after user upstream data in PSA is acquired9TEID, obtained by querying said established second correspondence F3TEID, at obtaining F3After TEID, the first correspondence relationship established above may be further queried to obtain user information, and the user information obtained through querying and the user operation behavior extracted from the user uplink data are associated and backfilled, so that the user information of the control plane and the user operation behavior of the user plane are bound, the association of the user information of the N9 interface is realized, and the integrity of the user data is ensured.
According to the technical scheme of the embodiment of the invention, the user information query corresponding relation is established by collecting the session messages between the AMF and the SMF and between the SMF and the UPF, so that when the user operation behavior of the N9 interface is obtained, the comprehensiveness of the user information during the associated backfill of the user information of the N9 user plane data is ensured based on the corresponding relation, and the accuracy of the associated backfill result is improved.
