Abstract

A system installed in a dual-mode mobile phone for automatic transfer of incoming phone call is used to automatically switch a GSM network incoming phone call to a PHS network, and includes: a detection module and an incoming phone call transfer module. The detection module is used to detect whether a mobile phone is within a PHS network. The incoming phone call transfer module is used to automatically transmit a signal to a GSM server to set an incoming phone call transfer function based on the detection result from the detection module. Thus, when the detection module has detected that a mobile phone is located within a PHS network, the incoming phone call transfer module transmits a signal to set an incoming call of the GSM network to be transferred to a PHS network; when the detection module has detected that a mobile phone has left a PHS network, the incoming phone call transfer module transmits a signal to stop the incoming phone call transfer functions.

Description

1229538_ V. Description of the invention (1) ‘Technical field to which the invention belongs: The present invention relates to an automatic call forwarding system, especially an automatic call forwarding system applied to a GSM / PHS dual-mode mobile phone. Prior technology: Mobile communication receives and transmits communication signals through satellites or commonly installed base stations. Both parties of the call use a hand-held mobile phone to receive and transmit communication signals with the base station to receive each other's communication signals in real time. Because the user and the base station transmit signals wirelessly, they can communicate with people as they want, regardless of the location. ′. The currently widely used mobile phone systems include the Global System for Mobile (GSM) and the Personal Handyphone System (PHS). Moreover, more and more users have become users of the above dual systems. In view of this, two operators have developed (GSM / PHS) dual-mode mobile phones. Users can use this phone to log in to the GSM network and PHS network at the same time, without having to prepare two mobile phones. Generally speaking, the 'GSM system has a wider coverage, and the communication cost of the ρηs system is relatively low. Therefore, some people often use the call forwarding function of mobile phones to transfer the incoming call settings of the GSM network to the PHS network. There is no charge for answering through the system, but both the caller and the receiver must charge for answering through the GSM system. Therefore, by this method of call forwarding, users only

However, due to the insufficient coverage of the PHS system, if the call forwarding is set by the above method, users often have to constantly change the call forwarding function of the mobile phone. If the signal of the PHS system is sufficient, the setting will be transferred to the PHS system mobile phone in the future. When there is insufficient signal in the PHS system, keep answering with a GSM mobile phone. Therefore, calls are often lost due to human negligence. In view of this, the present invention proposes a mobile phone network transfer system, which can automatically transfer incoming calls from the GSM network to the PHS network to answer, which is convenient for users to reduce call costs. SUMMARY OF THE INVENTION The object of the present invention is to provide an automatic call transfer system for automatically switching incoming calls from a GSM network to a pus network. The automatic call forwarding system of the present invention is set in a dual-mode mobile phone that supports two types of GSM and pHS protocols. The automatic call forwarding system includes a detection board group and a call forwarding module. Among them, the detection module is used to detect whether the module is located in the PHS network. The call forwarding module automatically sends a signal to the server of the GSM network according to the detection result of the “testing module” above to set the function of mobile phone call forwarding. When the detection module detects that the dual-mode mobile phone is in the PHS network, the incoming call = 2 will then send a signal to the GSM network consumer, and set the incoming calls on the G channel of the mobile phone to be transferred to the PHS network. And when the inert measurement module debt detects this dual-mode 1229538_ V. Description of the invention (3) The mobile phone leaves the PHS network, and the 'call transfer module immediately sends a signal to the GSM network feeder to stop the aforementioned function of mobile phone call transfer .
