Embodiment Construction

[0030] At present, when a mobile terminal measures cells of a different system according to the 3GPP protocol, in some cases, the measurement interval between two adjacent cells of a different system is as long as several hundred frames. Therefore, when the mobile terminal is in the DRX state, the current In an environment with poor communication mode signals, network drops often occur due to long measurement intervals.

[0031] In view of the above problems, the embodiments of the present invention provide a mobile terminal inter-system cell measurement method, which controls the difference between the i-th inter-system cell measurement and the i+1-th inter-system cell measurement of the mobile terminal. The value range of the interval is [90 frames, 150 frames], which can effectively reduce the occurrence of disconnection of the mobile terminal in the DRX state due to the excessively long measurement interval for cells of different systems.

[0032] In order to make the above-men...

Abstract

The invention relates to a mobile terminal and an inter-system cell measurement method thereof. The inter-system cell measurement method comprises the step of controlling a value range of an interval between an ith time of inter-system cell measurement and an (i+1)th time of inter-system cell measurement of the mobile terminal to be [90 frames, 150 frames], wherein the i is a positive integer. Occurrence of a circumstance that the mobile terminal fails in access to the network under a DRX (Discontinuous Reception) state because the interval of the inter-system cell measurement is too long can be effectively reduced by applying the method.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal and a method for measuring cells of different systems. Background technique [0002] In a mobile communication system, after the mobile terminal is powered on, it resides in a suitable serving cell through the initial cell search process, and gradually establishes 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 "neighbor cells"), and continuously track and measure the communication quality of the detected neighbor cells in order to prepare for cell reselection and handover. . Among them, the process in which the mobile terminal detects neighboring cells and performs tracking measurement is called cell measurement. [0003] According to the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) regulations, when a mobile termina...
