Problems solved by technology

When GSM and PHS are in dual standby mode, if the GSM mobile terminal runs on 1800MHz and the PHS mobile terminal runs on 1900MHz, at this time, the radio frequency of the two will interfere with the signal when calling and other states, especially for the PHS mobile terminal. The impact will be greater; as a result of interference, the voice quality will be poor, and even lead to the inability to make normal calls.

Embodiment Construction

[0018] The specific embodiment of the technical solution of the method of the present invention is described in further detail below:

[0019] A dual-mode mobile terminal of the present invention realizes a dual-standby calling method. Without changing the parameters of the current PHS system network and the GSM network, the PHS and GSM dual-mode mobile terminals of the present invention can adopt the method of closing the radio frequency that will cause interference. The method of making another kind of system can realize calling normally without interference; The specific implementation of the technical solution of the method of the present invention comprises the following steps:

[0020] Step 1: The PHS and GSM dual-mode mobile terminal starts a call in one of the standards, and determines the current calling system. In the case of dual standby, whether the dual-mode mobile terminal initiates a call or an incoming call, judge the system of the current call, and mark whethe...

Abstract

The invention relates to a page method of double wait in double-mode mobile terminal. Wherein, under PHS and GSM modes, it comprises followings steps that when one mode has page, the mobile terminal judges if closes the 1800M point of GSM, if closes the point, it sets relative parameters and opens the 900M point; or else, not closes the point, and processes normal page; when clearing the page, ifcloses the 1800M point, and the 900M point is not opened, opens closed 1800M radio, to recover relative parameters; if the 1800M point is closed, and 900M point is opened successfully, not opens the 1800M point; at last, backing to the state before paging. The invention decides close or open 1800M point based on the page mode, to avoid signal interference and confirm page quality.

Description

technical field [0001] The invention relates to a GSM and PHS dual-mode mobile terminal, in particular to a method for a PHS and GSM dual-mode mobile terminal to realize calling during dual standby. Background technique [0002] "Personal Handy-phone System" (PHS for short), also known as wireless local telephone system, is a personal wireless access system. PHS mobile phone has the same convenient mobility as GSM mobile phone and CDMA mobile phone, and its outstanding feature is that the transmission power is very small, which means that the radiation damage to the human body is small, the average power of the call is within 10mW, and the peak power is also within The range of 80mW is far less than the transmission power of GSM mobile phones. The peak power of GSM mobile phones is 2W, which is much smaller than the commonly known "green mobile phone" CDMA mobile phone (usually 0.2W), which can be called a real green mobile phone. At the same time, due to the extension and ...
