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

Embodiment Construction

[0042] At present, the application of multi-card mobile terminals has become more and more extensive, but the network cells where the cards of multi-card mobile terminals reside are generally not synchronized. Accurately receiving frame data has become a technical problem that needs to be solved urgently.

[0043] In the multi-card mobile terminal, when the first terminal card is on standby in the cell of the first network, to accurately locate the position of the frame of the cell of the second network that the second terminal card needs to receive is that the second terminal card accurately receives the signal, Basics of decoding signals. In view of this problem, the inventor proposes a method for determining the frame position of the mobile terminal, such as figure 1 shown, including:

[0044] Step S1, recording the extended frame number of the initial frame of the first network where the first terminal card is located when the first terminal card is synchronized with the s...

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 technical field of mobile communication, in particular to a mobile terminal, a frame position determination method and device thereof, and a frame receiving method. Background technique [0002] The third-generation mobile communication system is attracting more and more users' attention and use because of 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 effects, and still has its unique advantages. Therefore, a multi-mode multi-card multi-standby mobile terminal capable of supporting both the third-generation mobile communication system and the second-generation mobile communication system emerges as the times require. Taking an existing dual-mode dual-card dual-standby mobile terminal as an example, it mainly supports Time Division-Synchronou...
