Problems solved by technology

The mobility of the UE in the connected state is controlled by the eNB, and the mobility status of the UE is evaluated by the eNB, and the UE cannot know its own mobility status
[0003] During the high-speed or medium-speed movement of the UE, when the UE is in the connected state, because the UE does not know its own mobile state, the measurement may not be completed, and the cell where the UE resides has changed, resulting in the UE being unable to switch in time Going off the grid to the target community

Embodiment Construction

[0076] When the UE is in the connected state, the network side configures the neighboring cells around the cell where the UE resides to the UE through measurement configuration. When necessary, the UE measures these neighboring cells and reports the measurement results to the network side. The network side decides whether to handover the UE to another cell according to the measurement result and the current network side load.

[0077] When the UE is in the connected state, since the UE does not know its own mobility state, it will perform neighbor cell measurement and report the neighbor cell measurement report according to the measurement parameters in the low-speed motion state. However, when the UE is moving at a high speed or at a medium speed, if the measurement parameters in the low-speed motion state continue to be used, the measurement may not be completed and the cell where the UE resides has changed, resulting in the UE being unable to switch to the target in time. ...

Abstract

A user terminal control method, mobility acquisition method and device, the control method includes: judging whether an RRC connection reconfiguration message sent by the network side is received; when the RRC connection reconfiguration message is received, from the Obtain the motion state indication information in the above RRC connection reconfiguration message; when the cell handover is completed, according to the motion state indication information, perform the operation in the connection state corresponding to the motion state, and the operation in the connection state includes neighboring cell measurement operation and reporting Neighborhood measurement report. By adopting the method and device, it is possible to avoid the phenomenon that the user terminal is disconnected from the network.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for controlling a user terminal, a method and a device for obtaining mobility. Background technique [0002] When a user terminal (User Equipment, UE) is wirelessly connected to a base station (evolved NodeB, eNB), it is called a radio resource control (Radio Resource Control, RRC) state of the UE is a connected state. The mobility of the UE in the connected state is controlled by the eNB, and the mobility status of the UE is evaluated by the eNB, and the UE cannot know its own mobility status. [0003] During the high-speed or medium-speed movement of the UE, when the UE is in the connected state, because the UE does not know its own mobile state, the measurement may not be completed, and the cell where the UE resides has changed, resulting in the UE being unable to switch in time To the target community and off the grid. Contents of the invention [00...
