Mobile terminal, mobile-terminal frame position determining method and device, and mobile-terminal frame reception method

Abstract

The invention provides a mobile terminal, a mobile-terminal frame position determining method and device, and a mobile-terminal frame reception method. The frame position determining method comprises the steps of recording the expanded number of an initial frame of a first network, the number of an initial frame of a second network, and the deviation of the initial frame of the second network relative to the initial frame of the first network; determining the number of a present frame of the second network and the number of an object frame of the second network; and determining the expanded number of an object frame of the first network, and the deviation of the object frame of the second network relative to the object frame of the first network. According to the technical scheme of the invention, the problem of positioning the reception position of the object frame of the second network under the condition that a second terminal card is synchronous with a first terminal card can be solved, and due to introduction of the expanded frame numbers, the positioning process is more rapid, and the efficiency of the mobile terminal is improved.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a mobile terminal, a method and device for determining frame position thereof, and a frame receiving method. Background technique [0002] The third-generation mobile communication system is getting more and more users' attention and use with its more efficient spectrum efficiency, higher service quality and confidentiality performance, and higher service rate. However, the second-generation mobile communication system has wider network coverage and stable call effect, which still has its unique advantages. Therefore, a multi-mode, multi-card and multi-standby mobile terminal that can support both the third-generation mobile communication system and the second-generation mobile communication system has emerged. Take an existing dual-mode dual-card dual-standby mobile terminal as an example. It mainly supports Time Division-Synchronous Code Division Multiple Acce...

Problems solved by technology

But the existing technology only solves the problem of the initial synchronization of the two cards, and does not consider the problem of how to accurately obtain the receiving position of the target frame of the other terminal card when one of the terminal cards is on standby after synchronization

For example, referring to the patent of U.S. Patent Publication No. US2010222064A1, a TD-SCDMA / GSM dual-mode dual-card dual-standby mobile phone is disclosed. When the GSM terminal card is in the standby state, the initial synchronization of the TD-SCDMA terminal card and the GSM terminal card problems, but the above technical problems are still not resolved
