Adjacent cell measurement method of multimode multi-card multi-standby mobile terminal

Abstract

The invention relates to an adjacent cell measurement method of a multimode multi-card multi-standby mobile terminal in the technical field of mobile communication. The method comprises the following steps of: acquiring the broadcast information of each card, wherein the broadcast information comprises mode information, service cell information and adjacent cell list information corresponding to each mode of a service cell; carrying out merging processing on at least two pieces of adjacent cell list information corresponding to the same mode to obtain an adjacent cell union set list corresponding to each mode; and respectively measuring the parameter information of each cell in each adjacent union set list. Due to the adoption of the adjacent cell measurement method, the cost of the mobile terminal is reduced, the power consumption of the mobile terminal is reduced, and meanwhile, the same frequency processing performance of a TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) mode is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for measuring neighboring cells of a multi-mode, multi-card and multi-standby mobile terminal. Background technique [0002] The development of mobile communication has formed a variety of mobile communication networks, such as the second generation mobile communication system (2G): Global System for Mobile Communication (GSM, Global System for Mobile Communication), General Packet Radio System (GPRS, General Packet Radio System) ), enhanced data rate GSM service (EDGE, Enhanced Data rates for GSM service), code division multiple access (CDMA, Code Division Multiple Access), third generation mobile communication system (3G): unified mobile communication system (UMTS, Universal Mobile Telecommunications System, also known as Wideband Code Division Multiple Access (WCDMA, Wideband CDMA)), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time ...

AI Technical Summary

Problems solved by technology

[0011] 1) Since the same cell may exist in the first neighbor list and the third neighbor list, the same cell may also exist in the second neighbor list and the fourth neighbor list, which is As a result, two repeated measurements will be performed on the same cell, thereby increasing the overhead of the mobile terminal, resulting in high power consumption

Similarly, in multi-card multi-standby mobile terminals with three cards, three standbys and above, the probability of repeated measurement of the same cell is greater

[0012] 2) Since the TD-SCDMA mode is a same-frequency network, the carriers between adjacent cells may be the same. Based on the reality of the network, there are often cases of cross-region coverage, which aggravates the situation of same-frequency interference

The measurement of the above technologies is not conducive to the mobile terminal's comprehensive acquisition of the potential co-channel interference of the network, which in turn affects the co-channel processing performance

Similarly, in multi-card multi-standby mobile terminals including TD-SCDMA mode, the probability of co-channel interference will be greater, which will affect the communication performance of mobile terminals
