Method for realizing incoming call branching in double-mode cell phone

Abstract

A method for realizing incoming call transfer of double mode mobile phone includes setting a special option for transferring a incoming call in mobile phone with GSM communication system and PHS low power communication system, automatically transferring the incoming call from GSM communication system mode to PHS low power communication system mode for receiving said call in low power special option software when incoming call conforming to said option set in double mode mobile phone is received under GSM communication system mode .

Description

technical field [0001] The present invention relates to a method for implementing incoming call transfer in a dual-mode mobile phone, especially to a method for adding a setting option on a dual-mode (GSM / PHS) mobile phone, and the setting option includes a setting for special transfer of incoming calls number and a set special transfer target number, etc., so that through the detection of a special call transfer setting software on the dual-mode mobile phone, the incoming call of a GSM communication system can be automatically transferred to the PHS low-power communication system mode for answering, In this way, the user can reduce the impact of the radiation on the health of the GSM communication system when receiving calls from the GSM communication system, and can also greatly reduce the call cost of the mobile phone. Background technique [0002] Today's society is an era of information and knowledge explosion. Information exchange and communication between people is be...

[0003] In addition, with the advancement of the electronic industry, many people in today's society cannot do without mobile phones in their work and life, and the use of Global System for Mobile Communication (Global System for Mobile Communication, hereinafter referred to as GSM) communication in mobile phones has become very common. However, The mobile phone using the GSM communication system has a large radiation to the human body, which is not conducive to health, and when the user answers the call from the GSM communication system, because the operator often has various preferential plans, there is no need to pay for some incoming calls, while others Some incoming calls need to be paid, and among these charges, some are more expensive and some are lower.

[0004] In addition, the recently launched and popular "Wireless Local Phone PHS", that is, Personal Handyphone System, hereinafter referred to as PHS, is a low-power communication system, and its basic functions are similar to those of the GSM communication system. The advantage is that the PHS communication system uses microcell base stations to send signals, which has a small coverage area and slow moving speed. It is more suitable for the population in urban areas. Although it is cheap, it can only be used within a limited range. , having said that, the PHS low-power communication system has brought a lot of benefits to users with its advantages of low radiation, free incoming calls, etc.

[0005] Based on the above two communication methods, because they have their advantages and disadvantages respectively, they cannot fully satisfy the needs of any one person, so the appearance of so-called "dual-mode (GSM / PHS) mobile phone" has just occurred in the mobile phone market. GSM / PHS) mobile phone” is a mobile phone that can use both the GSM communication system and the PHS low-power communication system of PHS

[0006] And because the "dual-mode (GSM / PHS) mobile phone" combines the advantages of the GSM communication system and the PHS low-power communication system to use, in fact, the user uses the "dual-mode (GSM / PHS) mobile phone" / PHS) mobile phone” to answer the incoming call of the GSM communication system, how to deal with the various preferential plans (for example, various preferential package activities emerging in endlessly) for the aforementioned operators, the “dual-mode (GSM / PHS) mobile phone” automatically Choose to answer those incoming calls that are free of charge, and you can directly use the GSM communication system to answer them. If you need to pay or charge a high fee to answer those incoming calls, you can transfer them to the free PHS low-power communication system or Other free answering terminals answer, and then achieve the purpose of saving the user's call fee; but, in terms of this "dual-mode (GSM / PHS) mobile phone" at present, in fact, all cannot reach the above-mentioned switching requirements, but can only To achieve a general transfer method
