Abstract

The invention relates to the field of communication and discloses a method for measuring a TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) cell in a GSM (Global System for Mobile Communication) mode and a dual-mode terminal. The method comprises the following steps of judging if the position of the dual-mode terminal is changed relative to the position thereof during carrying out measurement sequencing on each RSSI (Received Signal Strength Indicator) before carrying out measurement sequencing on the RSSIs of TD-SCDMA cell frequency points again according to the preset period; carrying out measurement sequencing on the RSSIs again if the position is changed and completing the measurement of the TD-SCDMA cell through subsequent operations; and forbidding the current measurement sequencing on the RSSIs if the position is not changed. Compared with the prior art which caries out measurement sequencing on the RSSIs of more than nine TD frequency points and subsequent operations at intervals (30s), the invention greatly reduces the power consumption of the dual-mode terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a technique for measuring a TD-SCDMA cell by a dual-mode terminal. Background technique [0002] With the continuous development of communication technology, various types of wireless communication systems have appeared, such as Global System for Mobile communication (Global System for Mobile communication, referred to as "GSM"), Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, referred to as " WCDMA"), Time Division Synchronous Code Division Multiple Access (TD-SCDMA for short), Worldwide Interoperability for Microwave Access (WiMAX for short), Long Term Evolution (LongTerm Evolution, short for "LTE"), Bluetooth, China Mobile Multimedia Broadcasting ("CMMB" for short), etc. [0003] At present, many terminals (such as mobile phones) can support two kinds of wireless systems (or wireless standards), such as supporting both GSM and TD-SCDMA. Such a termin...
