Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
As mentioned in the background art, the user plane traffic only includes information such as user IP address, N3 interface information, TEID, etc., and lacks user information such as phone number, etc., the original correlation method is to extract information such as user session N3 interface information, phone number, SUPI, etc., from the signaling interaction flow by obtaining the original signaling plane traffic, and store the information in the memory, and then perform correlation backfill according to the N3 interface information and the user plane traffic. Because of the large base number of the user, the associated records in the memory, such as the N3 interface information, the telephone number, the SUPI and other information, will set the TTL value for the associated information when the associated information is initially learned, and will reset the TTL value of the associated information when the same record is subsequently learned. However, in the current network application, because the terminal device does not move online for a long time, no control plane signaling occurs, the DPI system cannot update the record in the memory, and after the TTL value of the associated information is reduced to 0, the record is deleted, which may cause that part of the user plane traffic is not backfilled in association, further cause the loss of the ticket data, and reduce the accuracy of data analysis.
Based on this, the disclosure provides a method and a device for managing associated information, an electronic device and a storage medium, when a TTL value of the associated information is smaller than a preset threshold, the disclosure sends a request message to an SMF network element, subscribes to signaling plane information of a terminal device, and updates or deletes the associated information according to a result of information returned by the SMF network element. The problem that the associated information is lost due to the fact that the user terminal network is online and does not move for a long time is solved, the NEF network element obtains the signaling plane information from the SMF network element, the associated information of the terminal equipment is automatically updated, and it is guaranteed that the user plane flow can be backfilled in an associated mode.
As shown in fig. 1, fig. 1 shows a schematic diagram of a communication system architecture to which the association information management method of the present disclosure can be applied.
Some relevant functional entities comprised in the communication system are described below.
A User Equipment (UE) accesses a Data Network (DN) or the like by accessing an operator Network, and may use a service provided by an operator or a third party on the DN. For convenience of description, a user terminal, a user equipment, a terminal device, or a terminal in the embodiments of the present disclosure may be collectively referred to as a UE. That is, unless otherwise specified, UEs described later in the embodiments of the present disclosure may be replaced by a user terminal, a user equipment, a terminal device, or a terminal, and of course, they may be interchanged with each other.
An Access and Mobility Management Function (AMF) is a control plane Function in the 3GPP network, and is mainly responsible for Access control and Mobility Management of UE accessing to an operator network. The Security Anchor Function (SEAF) may be deployed in the AMF, or the SEAF may also be deployed in another device different from the AMF, for example, the SEAF is deployed in the AMF. When the SEAF is deployed in the AMF, the SEAF and AMF may collectively be referred to as the AMF.
The SMF network element is a control plane function in a 3GPP network, where the SMF is mainly used for managing a Packet Data Unit (PDU) session of a UE. The PDU session is a channel for transmitting PDUs, and the UE can transmit the PDUs to each other through the PDU session and the DN. The SMF is responsible for management work such as establishment, maintenance and deletion of PDU sessions.
A Data Network (DN), also called a Packet Data Network (PDN), is a Network that is located outside of the 3GPP Network. The 3GPP network can access a plurality of DNs, and a plurality of services provided by operators or third parties can be deployed on the DNs. For example, a DN is a private network of a smart factory, and sensors installed in a plant of the smart factory play the role of UEs, and control servers of the sensors are deployed in the DN. The UE communicates with the control server, and after acquiring the instruction of the control server, the UE can transmit the acquired data to the control server according to the instruction. For another example, the DN is an internal office network of a company, and a terminal used by an employee of the company may play the role of a UE, which may access information and other resources within the company.
The UDM is mainly responsible for storing subscription Data, credentials (trusted identity), and Permanent identity Identifier (SUPI) of a Subscriber (UE) in the 3GPP network. These data may be used for authentication and authorization of the UE to access the operator 3GPP network.
Among them, a Network Exposure Function (NEF) is also a control plane Function in the 3GPP Network. NEF is mainly responsible for opening the external interface of 3GPP networks to third parties in a secure way. When the functional entities such as the SMF need to communicate with a third-party network element, the NEF may be used as a relay for communication. When relaying, the NEF can translate the internal and external identifiers. For example, when the SUPI of a UE is sent from a 3GPP network to a third party, the NEF may translate the SUPI into its corresponding external Identity (ID). Conversely, the NEF may translate the external identity ID into the corresponding SUPI when sending it to the 3GPP network.
The Network storage Function (NRF) is also a control plane Function in the 3GPP Network, and is mainly responsible for storing configuration service data (profile) of an accessible Network Function (NF), and providing discovery service of the Network Function for other functional entities.
The User Plane Function (UPF) is a gateway for the 3GPP network to communicate with the DN.
A Policy Control Function (PCF) is a Control plane Function in 3GPP networks, which is used to provide the Policy of PDU sessions to SMFs. The policies may include charging, Quality of service (QoS), authorization related policies, and the like.
AN Access Network (AN) is a sub-Network of the 3GPP Network, and a UE first needs to pass through the AN to Access the 3GPP Network. In a Radio Access scenario, AN is also called a Radio Access Network (RAN), and thus two terms, RAN and AN, are often used in a mixed manner without distinction.
A 3GPP network refers to a network conforming to the 3GPP standard. Here, the parts except for the UE and the DN in fig. 1 may be regarded as a 3GPP network. The 3GPP network is not limited to the 5G network defined by 3GPP, and may include 2G, 3G, and 4G networks. Typically 3GPP networks are operated by operators. In addition, N1, N2, N3, N4, N6, etc. in the architecture shown in fig. 1 represent Reference points (Reference points) between the related network entities/network functions, respectively.
The present exemplary embodiment will be described in detail below with reference to the drawings and examples.
First, the embodiment of the present disclosure provides a method for managing associated information, which may be applied to a DPI system or executed by any electronic device with computing processing capability.

it should be noted that the request message may include a type of signaling plane information, the target signaling plane information is user information associated with an N3 interface of the UPF network element, the user information may be one or more of user identity, user terminal call number, user location information, and the like, the preset threshold may be freely set according to an actual requirement, for example, the preset threshold is set to 5 minutes, when the associated information is not continuously obtained and a TTL value of the associated information decreases to less than 5 minutes along with time, the request message is sent to the SMF network element through the NEF network element, the signaling plane information of the terminal device is subscribed, and the SMF network element may return corresponding signaling plane information according to the type of the signaling plane information carried in the request message.
And S208, updating or deleting the associated information according to the result of the information returned by the SMF network element.
It should be noted that after the request message is sent to the SMF network element, it is determined whether the target signaling plane information of the terminal device returned by the SMF network element can be received, and if the target signaling plane information can be received, the association information is updated according to the target signaling plane information; and if the target signaling plane information cannot be received, deleting the associated information so as to manage the associated information according to the result of the information returned by the SMF network element.

The problem that the associated information is lost due to the fact that the user terminal network is online and does not move for a long time is solved, the NEF network element obtains the signaling plane information from the SMF network element, the associated information of the terminal equipment is automatically updated, and it is guaranteed that the user plane flow can be backfilled in an associated mode.
Further, when the TTL value of the associated information is less than the preset threshold, a request message is sent to the SMF network element to obtain the target signaling plane information from the SMF network element, and the disclosure subscribes, to the SMF network element of the core network, only a small amount of signaling plane information corresponding to the associated information whose TTL value is soon due, which has less influence on the performance of the core network element than subscribing to the signaling plane information of the full amount of online terminal devices.
