Embodiment Construction

[0094] 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.

[0095] 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 UE idle state processing method, MM functional entity and SM functional entity. The method includes: the mobility management MM function receives a connection release request sent by an access network entity, wherein the connection release request carries UE identification information; the MM function sends a user plane connection deactivation request to the SM function according to the connection release request, and the user plane connection deactivation request is used to request the SM function to delete the user plane connection of the UE, And maintain the signaling plane connection of the UE. In this way, when the UE is in the idle state, the user plane between the UE and the core network is not maintained, but the signaling plane is still maintained, which can effectively save UP resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a UE (User Equipment, user terminal) state switching method, MM (Mobility Management, mobility management) functional entity and SM (Session Management, session management) functional entity. Background technique [0002] In the prior art, when the UE is in an inactive state, it needs to enter the idle state; when the UE or the network needs to perform data transmission, it needs to trigger the UE to enter the connected state from the idle state. With the continuous development of mobile communication technology, the future mobile communication network may support the separation of control and forwarding of the gateway, and separation of MM and SM. However, for the situation where the MM is separated from the SM, there is no method for implementing UE state switching in the prior art. Contents of the invention [0003] The purpose of the present invention is to ...
