Embodiment 1

[0056] Embodiments of the present invention provide a data transmission method, such as image 3 Shown include:

[0057] S101. When the core network device establishes the first bearer channel between the UE and the first server, obtain the service transfer point list of the UE and the adjacent server list of the first server; wherein the adjacent server list includes at least one second server, the service The transfer point list includes at least one service transfer point, and each service transfer point corresponds to a core network device.

[0058] Specifically, in an actual application, before the core network device establishes the first bearer channel between the UE and the first server, the following steps are further included:

[0059] 1. AF needs to open the function to the network (English full name: network exposure function, abbreviation: NEF) to subscribe to the UPF list with AF as the destination address, UPF topology value, and transmission channel detection ...

Embodiment 2

[0160] Embodiments of the present invention provide a data transmission method, such as Figure 11 Shown include:

[0161] S201. The AMF acquires a bearer request sent by the UE, where the bearer request includes the application address of the first server.

[0162] S202. The AMF determines the service transfer point list of the first server according to the application address. The service transfer point list includes at least one service transfer point, and each service transfer point corresponds to a core network device.

[0163] S203. The AMF determines the core network device currently serving the UE according to the service transfer point list, and sends the bearer request to the core network device, so that the core network device establishes the first bearer channel between the UE and the first server according to the bearer request Afterwards, the adjacent server list and the service transfer point list of the first server are obtained, and when it is determined that...

Embodiment 3

[0185] Embodiments of the present invention provide a core network device 10, such as Figure 18 Shown include:

[0186] The transceiver unit 101 is configured to obtain the service transfer point list of the UE and the adjacent server list of the first server when the processing unit 102 establishes a first bearer channel between the UE and the first server; wherein the adjacent server list includes at least one Second, the service transfer point list includes at least one service transfer point, and each service transfer point corresponds to a core network device.

[0187]The processing unit 102 is configured to determine that when the service transfer point list acquired by the transceiver unit 101 changes, according to the service type requested by the UE, determine that there is a service transfer point in the service transfer point list that satisfies the first preset condition, and satisfies When the core network device corresponding to the service transfer point of th...

Abstract

The embodiment of the invention provides a data transmission method, core network equipment and an AMF, which relate to the technical field of communications and solve the problem of how to ensure thelowest transmission delay of a transmission channel while establishing the transmission channel between a UE and a UPF. The method comprises the steps that when core network equipment establishes a first bearing channel between UE and a first server, acquiring an adjacent server list and a service transfer point list of the first server; and when it is determined that the service transfer point list is changed, determining that a service transfer point meeting a first preset condition exists in the service transfer point list according to the service type, and when the core network equipmentcorresponding to the service transfer point meeting the first preset condition is different from the core network equipment currently providing service for the UE, instructing the core network equipment corresponding to the service transfer point meeting the first preset condition to reestablish a second bearing channel between the UE and the first server through the service transfer point meetingthe first preset condition, and releasing the first bearing channel.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method, core network equipment and AMF. Background technique [0002] In the fifth-generation mobile communication technology (English full name: 5th-generation, abbreviation: 5G) network architecture, edge computing technology enables operators and third-party services to be deployed near user equipment (English full name: user equipment, abbreviation: UE). Access to access points, thereby reducing end-to-end delay and transmission network load, enabling more efficient service delivery. The realization principle is that the 5G core network selects a user plane function entity (full English name: user plane function, UPF for short) close to the UE, and directs the service traffic to the local data network through the N6 interface on the UPF; , multiple UPFs may be deployed at the same location, resulting in the problem that the data transmission...
