Embodiment Construction

[0085] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and examples.

[0086] In order to meet the data transmission and reception requirements of the UE with a small amount of discontinuous data, save signaling overhead, and improve the efficiency of data transmission, the prior art proposes a solution that does not release the UE context when the UE connection is released. In this solution, when the UE is disconnected from the network, the UE and the network still save the context of the UE and suspend it. When the UE re-accesses the network, the network entities do not need to establish and transmit the context of the UE, nor does the network The UE context needs to be obtained from the UE, and the previously suspended UE context needs to be directly resumed, so as to reduce signaling overhead. ...

Abstract

The present invention provides a method for controlling a UE context and a UE connection, including: a first node obtains recovery requirement information about the UE; the first node decides whether to recover the UE context and / or the UE connection according to the recovery requirement information about the UE . The present application also discloses a device for controlling UE context and UE connection. The application of the present application can effectively reduce the overhead of signaling resources and improve the utilization rate of resources.

Description

technical field [0001] The present invention relates to wireless communication technology, and in particular, to a method and device for controlling UE context and UE connection. Background technique [0002] Modern mobile communication tends to provide users with high-speed transmission multimedia services, such as figure 1 As shown, it is a system architecture diagram of System Architecture Evolution (SAE). in: [0003] User Equipment (UE) 101 is a terminal device that supports network protocols. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network that includes base stations (eNodeBs / NodeBs) that provide UEs with an interface to access the radio network. The Mobility Management Entity (MME) 103 is responsible for managing the UE's mobility context, session context and security information. The Serving Gateway (SGW) 104 mainly provides functions of the user plane, and the MME 103 and the SGW 104 may be in the same physical entity. ...
