Abstract

The invention provides a base station for connection of a low-power and a high-power radio telephone network. The high-power radio telephone network comprises a first and a second terminal, while the low-power radio telephone network comprises a third terminal. The first terminal has a first interface for communication with an external device. The base station, which operates for the low-power radio telephone network, has a second interface compatible to the first interface, and communicates with the first terminal of the high-power radio telephone network through the connection of the first and second interface. Therefore, the third terminal of the low-power radio telephone network communicates with the second terminal of the high-power radio telephone network under the operation of the first terminal and the base station.

Claims

1. An apparatus for connection of a low-power and a high-power radio telephone network, the high-power radio telephone network comprising a first and a second terminal, and the low-power radio telephone network comprising a third terminal, wherein the first terminal has a first interface for communication with an external device, the apparatus comprising:

a base station with which the first terminal is integrated, operating for the low-power radio telephone network, having a second interface compatible to the first interface, communicating with the first terminal of the high-power radio telephone network in response to the third terminal of the low-power radio telephone network through the connection of the first and second interface, whereby the third terminal of the low-power radio telephone network communicates with the second terminal of the high-power radio telephone network under the operation of the first terminal and the base station;

wherein the first and the second interface both comprise a Mic Audio port, a Speaker Audio port and an Asynchronize Serial Port, the Mic Audio port, Speaker Audio port and Asynchronize Serial Port of the first interface are respectively connected to the Speaker Audio port, Mic Audio port and Asynchronize Serial Port of the second interface.

2. The apparatus as claimed in claim 1, wherein an audio signal and a control signal are transferred through the first and second interface.

3. The apparatus as claimed in claim 2, wherein the first and second interface both comprise ports for the audio and control signal.

4. The apparatus as claimed in claim 3, wherein the ports for the audio signal are an audio input and an audio output.

5. The apparatus as claimed in claim 3, wherein the ports for the control signal of the first and second interface connect with each other using an existing data suit of the first terminal.

6. The apparatus as claimed in claim 3, wherein the ports for the control signal of the first and second interface connect with each other by hardwired lines.

7. The apparatus as claimed in claim 6, wherein the port for the control signal of the first interface comprises a keypad scan pin and a ringer signal output, while the port for the control signal of the second interface comprises a control pin and a ringer signal input that respectively connects to the keypad scan pin and the ringer signal output of the first interface.

8. The apparatus as claimed in claim 1, wherein the first and the second terminals are GSM handsets.

9. The apparatus as claimed in claim 1, wherein the third terminal is a DECT handset.
