Problems solved by technology

That is to say, the original target cell for reselection may have experienced serious loss or fading, and there is a high probability that reselection will fail.
[0013] 2) The measurement of the UTRAN system in the current standard scheme does not distinguish between WCDMA and TD-SCDMA. Since the WCDMA bandwidth is 5M, which is much larger than the TD-SCDMA bandwidth of 1.6MHz, generally speaking, the number of TD-SCDMA frequency points is greater than that of WCDMA.
[0014] In addition, there is currently an improved solution to the standard technical solution, that is, when LTE measures different systems, the measurement period for any configured frequency point of different systems is uniformly 5*DRX (taking DRX=1.28s as an example ), although this solution shortens the reselection measurement delay, it has a great impact on the power consumption of LTE terminals in the idle state due to the increase in the number of measurements on different system frequencies

Abstract

The invention provides a method and a device for measuring an LTE terminal in an idle state, and belongs to the field of mobile communication. The method for measuring an LTE terminal in an idle state comprises the following steps: acquiring the current moving speed grade of an LTE terminal in an idle state; acquiring the current battery remaining power index R of the LTE terminal; and determining the measurement cycle of the LTE terminal for an intra-frequency cell, an inter-system cell and / or an inter-frequency cell according to the acquired moving speed grade and the battery remaining power index R. Through the technical scheme of the invention, the influence of inter-frequency and inter-system measurement on the power consumption of the terminal in an idle state can be reduced under the premise of ensuring the re-selection measurement performance.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for measuring an LTE terminal in an idle state. Background technique [0002] In the idle state, the terminal triggers cell reselection by monitoring the measured values ​​of the serving cell and neighboring cells. Neighboring cells may include intra-frequency cells of the same access system, inter-frequency cells, and inter-frequency cells of different access systems. Different from the 2 / 3G network, the reselection of the idle state under the LTE (Long Term Evolution, Long Term Evolution) network introduces the concept of priority. The reselection priority is divided according to the carrier frequency and configured by the network. The priority of different carrier frequencies Levels may or may not be equal. [0003] At present, the reselection measurement of the terminal under the LTE network mainly consists of the following steps: [0004] 1. The ter...
