In particular, various services such as voice call, data communication, short message service (SMS), voice dialing service, and information providing service using WAP (Wireless Application Protocol) are provided for the mobile communication service. To this end, mobile communication terminals such as cellular phones and PCS (Personal Communication System) have been developed and spread.

However, even if a wired or mobile communication service is provided, if a subscriber is not near a landline phone or does not carry a mobile communication terminal, the subscriber cannot receive a call.

To solve this problem, wired communication services and mobile communication services provide call forwarding services that allow subscribers to receive calls made from them at arbitrary locations.

In general, a call forwarding service may be provided by a subscriber registering a call forwarding request and a phone number to which his / her phone is forwarded to a company providing a wired or mobile communication service.

However, the conventional call forwarding service must bear the inconvenience of having to register the service directly whenever the service is needed.

Therefore, the present invention is a call forwarding method using a wireless communication invented to automatically set the call forwarding to the mobile terminal by checking the proximity of the wired telephone and the mobile terminal period by applying a wireless communication technology to solve the conventional inconvenience And to provide a system.

In particular, it is an object of the present invention to simplify the implementation by applying the RFID technology as a wireless communication technology to easily receive the call forwarding service.

The present invention provides a method for providing a call forwarding service by mounting a wireless module reader to a mobile terminal to achieve the above object, the wireless module reader detecting a signal of a wireless module attached to a wired telephone, the wireless If the output signal of the module is not detected, the mobile terminal requests the call forwarding to the wired communication network through the mobile communication network, and registers the call forwarding in the wired communication network, and converts the call to the wired telephone to the mobile terminal. It is characterized by.

After the call forwarding is set in the process, if the wireless module reader detects a signal of the wireless module installed in the wired telephone, the mobile terminal includes a step of requesting the call forwarding registration cancellation to the wired communication network through the mobile communication network. It is characterized by.

Call forwarding request in the above process is characterized in that executed only by the user's permission.

In addition, the present invention is a communication system for providing a call service by interlocking a mobile communication network and a wired communication network in order to achieve the above object, a wireless module attached to the wired telephone, and the signal of the wireless module while communicating with the wireless module Is equipped with a wireless module reader for detecting a wireless module reader, and if the signal of the wireless module is not detected in the wireless module reader, request a call transfer to the wired communication network through the mobile communication network, Characterized in that comprises a mobile terminal receiving a call of the.

Wireless communication technology applied to the present invention is Bluetooth, IrDA, RFID and the like.

Assuming that RFID technology is applied to the present invention, the wireless module mounted on the wireline telephone is an RFID tag, and the wireless module reader mounted on the mobile terminal is an RFID reader.

RFID is a wireless communication system consisting of an RFID tag that provides information and an RFID reader that reads and decodes the information. The RFID tag is information that identifies an object such as a person, a car, a cargo, or a livestock. Means.

Brief description of the characteristics of the RFID technology is as follows.

1. It can recognize several tags at the same time and save processing time.

2. It can be applied according to system characteristics or environmental conditions, so the application range is wide and system expansion is easy.

3. As there is almost no malfunction of the reader due to the non-contact method, it can be used semi-permanently and easy to maintain.

4. By programming tags with OTP (One Time Programming), it is impossible to falsify and tamper with data, thus maintaining complete security.

The RFID system of this feature is classified into an inductively coupled method and an electromagnetic wave method according to the mutual communication method.

The mutual induction method is used for near field (within 1m) RFID employing a coil antenna, and the electromagnetic wave method is used for medium to long distance (several meter range) using a square wave antenna.

That is, RFID tags are classified into passive tags of mutual induction type and active tags of electromagnetic wave type.

The mutually inductive tag is almost always operated manually. This means that all the energy required for the operation of the tag is supplied by the RFID reader. That is, the RFID reader generates a strong and high frequency electromagnetic field in the surrounding area in the antenna coil, and the tag rectifies it when a part of the emitted magnetic field generates an inductive voltage in the coil antenna and uses it as an operating power source.

In contrast, an electromagnetic tag includes a battery because the RFID tag does not receive sufficient power for driving the microchip therein. In this case, in order to prevent unnecessary loss of the battery, the internal microchip generally has a power down or standby mode. For example, if a tag is out of range of an RFID reader, the embedded chip automatically enters power down mode.

The RFID system can be remotely sensed and controlled by using a wireless device, such as an anti-theft device, animal tracking device, car safety device, personal access and access permit device, electronic toll collection device, production management, rail transportation container tracking device, etc. It will be able to provide many application services not only in life but also in industry.

Hereinafter, the present invention will be described in detail with reference to the drawings.
