Embodiment Construction

[0113] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0114] Separation of control and forwarding refers to the logical division of the control and forwarding functions of the mobile network, and the corresponding functions are assumed by different logical network elements, so as to realize centralized control of functions, flexible allocation of resources, flexible deployment of services, control plane and The user plane can evolve separately. The control function is undertaken by a centralized controller to implement functions such as policy control, traffic scheduling, connection management, and mobility management. Various applications can define network routing and transmission rules and policies based on business characteristics, without relying on the resources, performance and other constraints of t...

Abstract

The present invention provides a method and device for selecting a user plane anchor point. The method includes: a CP function receives a first data message sent by a UE; the CP function selects a first data message for the UE based on the first data message. Target user plane anchor UP‑GW. In this way, the user plane anchor point selection method of the present invention selects the UP-GW for the UE when receiving the data message sent by the UE, so that data transmission can better adapt to UP load and network topology changes, thereby improving data transmission efficiency .

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a user plane anchor selection method and device. Background technique [0002] IoT (Internet of Things, Internet of Things) users send data infrequently and suddenly. In order to efficiently realize data transmission, the current 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) has proposed a scheme for transmitting data packets using the control plane. In this scheme, UE (User Equipment, user terminal) sends The data message is sent to a selected UP-GW (User Plane-Gateway, user plane anchor point) through the control plane, and the UP-GW forwards the data message sent by the UE to a DN (Data Network, data network). [0003] In the prior art, the network selects the UP-GW for the UE when the UE requests to attach. However, due to reasons such as the mobility of the UE, the UP-GW may change, and the method of selecting the UP-GW fo...
