Abstract

The present invention relates to a method and an apparatus for changing a connection state of a UE. Disclosed are a method and a device for changing a connection state according to movement of a UE. More specifically, a method and apparatus for determining a connection state of a corresponding UE to reflect the connection state when the UE in a lightly connected state or an RRC inactive state moves is disclosed. A method for changing a connection state of a UE, comprising: receiving indication information from an evolved base station (eNB) indicating that the connection is changed to a specific RRC state; configuring the connection state of the UE to a specific RRC state based on the indication information and executing the UE according to the movement of the UE a cell reselection operation; and changing the connection state of the UE to an RRC idle state based on at least one of information about whether to start an RRC recovery procedure, system information and radio access technology information of a cell selected by the cell reselection operation, Wherein the specific RRC state is a state different from the RRC connected state and the RRC idle state.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Korean Patent Application Nos. 10-2016-0122506 and 10-2017-0104068 filed on September 23, 2016 and August 17, 2017, which are incorporated by reference for all purposes Incorporated herein as if fully set forth herein. technical field [0003] The present invention relates to a method and apparatus for changing a connection state according to movement of a UE. More particularly, the present invention relates to a method and apparatus for determining a connection state of a corresponding UE and reflecting the connection state when a UE in a light connection or Radio Resource Control (RRC) inactive state moves. Background technique [0004] With the development of communication systems, various wireless user equipments (UEs) have been utilized by consumers such as companies and individuals. Current mobile communication systems affiliated with 3GPP, such as Long Term Evolution (LT...
