Embodiment Construction

[0035] At present, according to 3GPP regulations, the interval between two adjacent inter-frequency measurements of the mobile terminal is sometimes as long as hundreds of frames. Therefore, in a weak signal environment, the mobile terminal has a high dropout rate in DRX state. Moreover, the power consumption of the mobile terminal is relatively high.

[0036] Aiming at the problem of high network drop rate in the DRX state of the mobile terminal, an embodiment of the present invention provides a mobile terminal cell measurement method, the method controls the jth inter-frequency measurement of the mobile terminal and the j+1th The value range of the interval between different-frequency measurements is [40 frames, 80 frames], which can reduce the occurrence of the mobile terminal being disconnected from the network due to too long inter-frequency measurement intervals.

[0037] Aiming at the problem of high power consumption of the mobile terminal, an embodiment of the present...

Abstract

The invention discloses a mobile terminal and a cell measurement method thereof. The method comprises the step: controlling the value of the interval between j-th pilot frequency measurement and (j+1)-th pilot frequency measurement of the mobile terminal to be in the range from 40 frames to 80 frames, wherein j is a positive integer. Through controlling the value of the interval between j-th pilot frequency measurement and (j+1)-th pilot frequency measurement of the mobile terminal to be in the range from 40 frames to 80 frames, the method can reduce the network outrage conditions, caused by the overlong interval of the pilot frequency measurement, of the mobile terminal.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a cell measurement method thereof. Background technique [0002] In the mobile communication system, after the mobile terminal is turned on, it will stay in a suitable serving cell through the initial cell search process, and gradually establish a wireless communication process. At the same time, the mobile terminal also needs to detect the cells adjacent to the serving cell (referred to as "neighboring cells"), and continuously track and measure the communication quality of the detected neighboring cells, so as to prepare for cell reselection and handover . Among them, the process that the mobile terminal detects neighboring cells and performs tracking and measurement is called cell measurement. [0003] According to the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP), when the mobile terminal performs cell measure...
