Problems solved by technology

The disadvantage of using two antennas is that a certain distance must be kept between the first antenna 11 and the second antenna 12, so that the PHS module and the GSM module can operate independently without interfering with each other, thus increasing the volume of the mobile phone and also increasing the Difficulty of mechanism and design
[0004] However, the prior art does not have a mobile phone that only uses a single antenna to receive and switch multi-frequency signals

Embodiment Construction

[0033] In order to enable your review committee members to better understand the technical content of the present invention, the preferred specific embodiments are described as follows.

[0034] The present invention uses the first communication mode of the mobile phone to search for the characteristics of the first communication signal at regular intervals, and switches the remaining time without searching for the first communication signal to the second communication mode in order to search for the second communication signal. When the time of the second communication signal expires, it will switch to the first communication mode again. As shown in Figure 2a, it is a schematic diagram of the principle of the present invention. The first communication mode takes the PHS mode as an example, and the second communication mode takes the GSM mode as an example. It is initially set to the PHS mode at the beginning, and the PHS mode of the mobile phone is used every 1.2 The second s...

Abstract

The provided mobile phone receiving multiple frequency signals with single antenna can switch between PHS and GSM / CDMA mode. This invention achieves dual-standby effect.

Description

technical field [0001] The invention relates to a multi-frequency signal switching method and a mobile phone using the method, in particular to a method for receiving multi-frequency signals with a single antenna and switching between different modes of the mobile phone, and a mobile phone using the method. Background technique [0002] At present, domestic mobile phone communication systems mainly include PHS (1900MHz frequency band) system and GSM system (900 / 1800MHz frequency band). The PHS system has the advantages of low call charges and low electromagnetic waves, but the PHS system is a regional communication system, and the base station coverage and roaming are not perfect. In addition, the GSM system is a communication system commonly used in various countries. The base station has complete coverage and has the advantages of international roaming. However, the disadvantages of the GSM system are high call charges and high electromagnetic waves. Because the PHS syste...
