Embodiment Construction

[0041] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, but not to limit the present invention.

[0042] After the mobile terminal is powered on and camps on the cell, determine the long measurement period T of the neighboring cell long (For example, it can be set to an integer multiple of the DRX cycle greater than 1) and a short measurement cycle T short (For example, it can be set to DRX cycle), set the previous signal measurement value M of the serving cell previous invalid. After the serving cell measurement period times out, the signal measurement of the serving cell is performed and the signal measurement result is acquired, and the following adaptive adjustment process of the neighbor cell measurement period is started.

Abstract

Disclosed is a method for adaptive adjustment of the measurement period of a neighbouring cell. The method includes: performing periodic measurement on a serving cell, and acquiring a previous signal measured value and a current signal measured value of the serving cell; obtaining a current signal cumulative difference of the serving cell using a signal measurement difference between the previous signal measured value and the current signal measured value; and comparing the current signal cumulative difference with a signal cumulative difference threshold, and adjusting the measurement period of a neighbouring cell according to the comparison result, wherein the current signal cumulative difference is an algebraic sum of signal measurement differences corresponding to the serving cell. At the same time, also disclosed is a device for adaptive adjustment of the measurement period of a neighbouring cell. The technical solution of the present invention can adjust the measurement period of a neighbouring cell in time while reducing the power consumption of a mobile terminal, thus acquiring an effective neighbouring cell signal measurement result, and increasing the success rate of cell reselection.

Description

technical field [0001] The present invention relates to a mobile communication terminal, in particular to a method for self-adaptive adjustment of a measurement period of a neighboring cell in a mobile terminal and a related device. Background technique [0002] The mobile terminal is in an idle state after powering on and camping on a cell, and obtains neighbor cell information from the system information of the serving cell. The mobile terminal periodically measures the signal of the serving cell and neighboring cells, and then selects the cell with better signal to camp on, thereby ensuring the performance of the network service. [0003] Considering the requirement of reducing power consumption, the mobile terminal usually sets the neighboring cell measurement period to a longer period of time. Taking the E-UTRAN cell where the mobile terminal resides in the evolved radio access network as an example, the measurement period of the radio access time division multiplexing...
