Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] figure 1 It is the main flowchart of the present invention, and its content has been described in the summary of the invention. figure 2 is a detailed flowchart of an embodiment of the present invention.

[0015] Step 1: The PHS and GSM dual-mode mobile terminal starts to make a call in one system, and turns off the radio frequency of the system not in call.

[0016] In the case of dual standby, whether it is a dual-mode mobile terminal calling or an incoming call, when one standby mode receives an initial signal, it sends an internal signal to turn off the radio frequency of the other standard that does not have a call, and sets the relevant Parameters, flags whether a call is originating or incoming and whether a signal has been sent to turn off the radio. Since it is the communication between different modules inside the...

Abstract

The invention relates to a method for initializing a call between the dual-mode mobile terminals of PHS and GSM, in which, if there is a call of one mode-service as the time of both the service modes are on, the call does not access normal procedure before the radio frequency of the other mode-service is turned off. When the call is removed, the relevant radio frequency which has been closed will be reinitialized. The described turning off and reinitializing functions are realized through sending internal signals. When calling, only one system is operating, so no signal interference will happen to each other.

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. 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 (low transmission power also 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 low. In the range of 80mW, it is far less than the transmission power of GSM mobile phones (peak power is 2W), and it 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 beneficial supp...
