Embodiment Construction

[0038] Refer below Figure 3 to Figure 5 , the method and device according to the present invention are described in detail.

[0039] The present invention proposes a compact, low-power solution to support accurate and reliable measurements and a robust handover process. The preferred implementation of this solution can not only solve the sparse measurement problem caused by DRX configuration, but also solve the problem of handover command delay caused by DRX.

[0040] In this solution, for the UE, the following steps are included:

[0041] i. Determine to discover adjacent cells;

[0042] ii. updating the DRX configuration of the user equipment;

[0043] iii. Based on the updated DRX configuration, perform handover measurement on the neighboring cell, and send a measurement report to the base station device to which the user equipment belongs.

[0044] Preferably, the UE may be in a first state (or called a normal state) or a second state (or called an alarm state). Wher...

Abstract

The invention provides a method for DRX (discontinuous reception) configuration and measurement in user equipment and base station equipment and aims to solve the technical problem that accuracy and reliability of cell switching measurement are reduced due to DRX. The method includes determining and discovering neighboring cells; updating DRX configuration of the user equipment, and updating DRX configuration of the base station equipment and the user equipment synchronously; performing switching measurement to the neighboring cells by the user equipment according to the updated DRX configuration, sending a measurement report to the base station equipment corresponding to the user equipment, and receiving the measurement report sent from the user equipment by the base station equipment. Accordingly, measurement flexibility is improved. Preferably, the updated DRX configuration is consistent with the measurement time, so that the measurement result is accurate and reliable.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a discontinuous reception (Discontinuous Reception) DRX technology in wireless heterogeneous network communication technology. Background technique [0002] At the RAN#51 meeting, the research item "Mobility Improvement in Heterogeneous Networks for LTE" was agreed. This study item needs to consider and ensure robust mobility functionality (including DRX functionality) under various supported UE (User Equipment) measurement availability assumptions, as well as UE power consumption and complexity. One challenge in heterogeneous network (HetNet) deployment is robust mobility functionality and reduced UE power consumption. Current standards address the challenge of UE power consumption by allowing the network to configure discontinuous reception (DRX) for UEs in connected mode. The parameterization of the DRX cycle involves a balance between power saving and latency. ...
