Problems solved by technology

However, the size of the DRX cycle is also related to the paging capacity of the network and the timeliness of measurement. The smaller the DRX cycle, the greater the paging capacity, and the larger the DRX cycle, the less timely the measurement. For scenarios where the wireless quality of the UE's environment changes rapidly , the measurement interval and measurement evaluation interval are too large to meet the requirements of cell selection and reselection

Abstract

The invention discloses a UE triggering based measurement optimization method and device in mobile scenes. The method includes the following steps: receiving terminal UE measurement characteristic determination parameters broadcast by a base station and measurement frequency factors corresponding to different measurement characteristics, wherein the UE measurement characteristic determination parameters include parameters characterizing wireless quality changes in wireless environment of UE; determining the measurement characteristics of the UE according to the UE measurement characteristic determination parameters, wherein the measurement characteristics include the degree of the wireless quality changes in the wireless environment of the UE; determining the measurement frequency factorscorresponding to the measurement characteristics; and modifying a predefined measurement interval reference value and a measurement evaluation interval reference value by using the measurement frequency factors to obtain the measurement interval and the measurement evaluation interval of the UE. The determination method for wireless quality measurement interval and measurement evaluation intervalcan save power consumption of UE to the greatest extent and improve the energy saving effect of UE in a NB-IoT system.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a method and device for measurement optimization in a mobility scenario triggered by a UE. Background technique [0002] Machine to Machine (M2M) communication is an important subject currently studied in the fifth-generation mobile communication technology (5G), and it is also an important application field of future wireless communication. In the M2M subject, in view of the characteristics of low-cost and low-throughput terminals, a research sub-topic of NarowBand-Internet of Things (hereinafter referred to as NB-IoT) is proposed, which is NB-IoT within a 200KHz spectrum bandwidth. IoT low-cost terminals (User Equipment, hereinafter referred to as UE) provide low-throughput wireless communication services. [0003] NB-IoT is mainly used to carry massive connection and delay-insensitive small data packet services. It must support the terminal's long standby...
