Problems solved by technology

[0004] In addition, even if the NEF is deployed at the edge of the network, the wireless information and UPF information that the NEF can obtain still needs to be released to the core network elements such as the Access and Mobility Management Function (AMF, SMF) For edge NEF, since signaling needs to bypass the core network, the delay of path transmission is still high

example 1

[0109] The example 1 as Figure 5 As shown, the Local NEF finds the Local UPF by interacting with the 5G control plane. The process is as follows:

[0110] 500. The UE establishes a PDU session through the Local NEF.

[0111] 501. The Local AF initiates an information opening request to the Local NEF, and the information opening request includes the IP address of the UE.

[0112] 502. The Local NEF initiates a query request to the corresponding BSF, and finds the corresponding PCF address (according to the UE IP address).

[0113] 503. The Local NEF initiates an information opening request to the corresponding PCF, and the information opening request includes the IP address of the UE.

[0114] 504. The PCF initiates a session policy update request to the SMF, the update request includes the UE IP address, and is used to request the UPF address corresponding to the UE.

[0115] 505. SMF finds the corresponding UPF ( Figure 5 Not PSA UPF), feedback the UPF ID or DNAI or UPF...

example 2

[0131] The example 1 as Image 6 As shown, a series of IP address pools and the UPF address corresponding to each IP address pool are configured on the local NEF, so as to establish the corresponding relationship between the IP address pool and UPF, and find the corresponding relationship through the Local NEF to find the Local UPF , the process is as follows:

[0132] 600. The UE establishes a PDU session through the Local NEF.

[0133] 602. The Local AF initiates an information opening request to the Local NEF, and the information opening request includes the IP address of the UE.

[0134] After receiving the information opening request, the Local NEF finds the corresponding Local UPF by looking up the corresponding relationship according to the IP address pool to which the IP address of the UE belongs.

[0135] 603. According to the address of the UPF, the Local NEF initiates the establishment of the Nx interface connection to the Local UPF, or calls the event exposure se...

Abstract

The embodiment of the invention provides a network information opening method and equipment, and the method applied to a local NEF comprises the steps: the local NEF obtains the identification information of a first local UPF; the local NEF establishes a first control plane interface between the local NEF and the first local UPF according to the identification information of the first local UPF; and through the first control plane interface, the local NEF requests network open information of a PDU session of a first terminal from the first local UPF, and sends the network open information to a local application function (AF). According to the embodiment of the invention, the acquisition of the network open information can be simplified, and the path transmission delay of the network open information is shortened.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and equipment for opening network information. Background technique [0002] figure 1 It is an architecture diagram of the fifth generation mobile communication (5G) system of the prior art, figure 1 It includes a variety of network elements, among which, the Network Exposure Function (NEF, Network Exposure Function) network element has a unified external interface in the form of an application program interface (API), and communicates with a third-party application function (AF, Application Function) or operator AF . The NEF network element in the prior art is often deployed at a relatively high position, usually at the core side of the network (for example, it is deployed on the operator's capability exposure platform, which is mostly in the core network equipment room). NEF can directly communicate with policy control function (PCF, Policy Control Func...
