Telephone system, mobile telephone and talking method thereof

Abstract

The invention relates to a telephone system, which belongs to the communication field. The telephone system comprises a mobile telephone wirelessly connected with a wireless communication network and a fixed-line telephone connected with a fixed-line telephone network by wires, wherein, a first sensing unit is embedded in the mobile telephone; a second sensing unit is embedded in the fixed-line telephone; and the first sensing unit and the second sensing unit mutually perform communication within the predetermined range for data transmission. The invention also provides a call method for the telephone system. The purpose that a number can be dialed on the mobile telephone and then is called out through the fixed-line telephone can be achieved by the call method; the mobile telephone and the fixed-line telephone can perform communication with the called party for the call at the same time; and when one available fixed-line telephone does not exist within the predetermined range or the fixed-line telephone is in the service condition, the mobile telephone can call the call out through the wireless communication network. The telephone system solves a plurality of problems for using the mobile telephone and the fixed-line telephone in the real life.

Description

technical field [0001] The present invention relates to a telephone system, more specifically, to a telephone system and a calling method thereof. The telephone system includes a mobile phone and a fixed phone. Background technique [0002] Both mobile phones and landline phones are now very common. The mobile phone is used in the wireless communication network, and the radiation generated by the radio wave of the phone for a long time will cause great harm to the human body; and the strength of the communication signal is determined by the distance between the mobile phone and the base station to which it belongs. The farther away from the base station, the stronger the signal. Poor, and it is related to the density of mobile phone users within a certain range of the mobile phone. For example, people often encounter places with weak signals such as residential areas with large populations and shopping malls, and sometimes there is almost no signal. The fixed telephone is u...

Problems solved by technology

Fixed telephones are connected to the telecommunications network through telephone lines. There is no radiation problem, and there is no signal strength problem, but its operation is more troublesome. For example, when dialing a phone number, it needs to input a number and a number.

[0003] When the mobile phone user is in a place where the communication signal is weak, or when the radiation is large in the wireless communication network, or when the balance of the mobile phone is not much, or when the user does not want to pay expensive roaming charges, or for various reasons, the mobile phone cannot temporarily It is troublesome to use and look at the number on the mobile phone, and when inputting numbers on the fixed phone, etc., these have brought certain restrictions to the user's use of mobile phones or fixed phones.

Therefore, it is necessary to combine mobile phones and fixed phones. At present, we have not seen mobile phones that can communicate with fixed phones at home or in offices to solve users' problems.
