Problems solved by technology

When the UE enters the sleep state, the trigger time is still running normally; when the UE returns to the active state, it will report the measurement report to the base station, and if the trigger time has expired at this time, the signal quality status of the serving cell and the neighboring cell at this time Already changed, in this way, it will cause handover failure or wireless link failure, which has a great impact on mobile performance

Embodiment Construction

[0027] Generally speaking, in order to ensure communication quality, the UE will perform measurement operations on the serving cell and neighboring cells according to the measurement parameters configured by the network in the active state of the DRX mode, generate measurement events under certain conditions, and trigger them at the trigger time (TTT, TimeToTrigger ) after timeout, report the measurement report when certain conditions are met. When configuring the DRX mode for the UE, the 3GPP protocol imposes certain restrictions on the measurement report reported by the UE to the network. For example, in order to prevent the UE from returning to the active state from the sleep state frequently due to the reporting of the measurement results, the UE tries to delay the reporting of the measurement results (including two modes of event reporting and periodic reporting) as much as possible, and wait until the next activation time to report (FromTS36 .331).

Abstract

The present invention discloses a method for reporting a measurement report of a measurement event, including: determining that a measurement event is generated in a user equipment UE in an activated state of discontinuous reception DRX mode; judging whether a first time to trigger corresponding to the measurement event is valid when it is determined that there is a measurement event generated; using, when it is judged that the first time to trigger is valid, the first time to trigger to time the measurement event; using, when it is judged that the first time to trigger is invalid, a second time to trigger to time the measurement event, such that the UE is in next one or next several activated states of DRX mode after the generation of the measurement event. The present invention can improve a success rate of mobility handover between cells or wireless link quality.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for reporting a measurement report of a measurement event. Background technique [0002] A base station in a wireless communication system, the base station may include BS, eNodeB, nodeB, node, BTS (BaseTransceiverStation, base transceiver station) or AP (AccessPoint, access point), etc., on the downlink to the user equipment, the user The equipment UE may include accessterminal, accesspoint, PDA (Personal Digital Assistant, personal digital assistant), laptop (notebook computer), etc., transmit data and / or control information, and receive data and / or control information of user equipment on the uplink. Similarly, the user equipment transmits data and / or control information for the base station on the uplink, and receives data and / or control information transmitted by the base station on the downlink. [0003] In the prior art, in order to meet or improve the per...
