Embodiment Construction

[0053] When instructing the UE to enter the idle state from the connected state, the base station may issue a special identifier called a resume ID (Resume ID) to the UE. When the UE enters the idle state, it will save the context information on the user terminal side configured by the base station when it accesses the network this time. The context information on the user terminal side mainly includes security algorithms, configuration parameters related to the media access control layer (L2), physical Layer-related configuration parameters and radio link control layer (L3)-related configuration parameters, such as parameters such as radio link failure and GTP tunnel information.

[0054] The base station side will save the context information of the UE on the base station side, and the context information of the UE on the base station side mainly includes configuration parameters related to the access layer. The MME will also store the context information of the UE on the MM...

Abstract

The invention relates to a base station, a connection recovery information configuration method, and a method and apparatus of connection recovery. The connection recovery information configuration method of the base station includes the steps: when determining that UE (user equipment) migrates to an idle state from a connection state, saving the context information, at the side of the base station, of the UE, and generating an RRC connection suspend signaling; and sending the RRC connection suspend signaling to the UE so as to control the UE to migrate to the idle state from the connection state. By means of the base station, the connection recovery information configuration method, and the method and apparatus of connection recovery, the success probability of connection recovery flow can be improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a base station, a method for configuring connection recovery information, and a connection recovery method and device. Background technique [0002] In a Long Term Evolution (LTE) system, after a user terminal (User Equipment, UE) enters the connected state, the base station will assign necessary parameters to the UE such as security algorithms, media access control layer (belonging to Layer 2) related Configuration parameters, configuration parameters related to the physical layer (Layer 1) and radio link control layer (Layer 3) related configuration parameters such as radio link failure and other parameters, for the established bearer, the base station needs to know the link established for the bearer The channel information between the core networks is the GTP tunnel, and the above parameters are called UE context (UE Context) information. [0003] In 3GPP Release 13, fo...
