Claims
- 1. A wireless communication device for a plurality of communication systems operable independently of each other under different communication protocols, the device comprising:a memory storing therein a fixed message; a plurality of communication parts connectable to the communication systems to receive calls therefrom; and a controller programmed to detect which one of the communication parts received a call in the middle of a communication through another of the communication systems, to further connect the detected communication part to one of the communication systems through which the call is received, and to transmit the fixed message in the memory to the connected communication system through the detected communication part in the middle of the communication through the another of the communication systems.
- 2. A wireless communication device of claim 1, wherein:the fixed message includes a request of sending a reply message in return of the fixed message; and the controller is further programmed to store the reply message in the memory means.
- 3. A wireless communication device of claim 1, further comprising:an indicator for indicating a reception of the call; and a key operation detector for detecting a key operation, wherein the controller is programmed to enable a transmission of the fixed message to the connected communication system only when the indicator is driven to indicate the reception of the call and the detected key operation is a predetermined one for a fixed message transmission.
- 4. A wireless communication device of claim 3, wherein:the controller is further programmed to switch a connection of the communication parts to the communication systems when the detected key operation is another predetermined one for a communication part switching, so that a communication through one of the one communication part and the another communication part is enabled while holding the other of the one communication part and the another communication part.
- 5. A wireless communication device of claim 4, wherein:the controller is further programmed to terminate the communication through the one of the one communication part and the another communication part, when the key operation is a further predetermined one for terminating an enabled communication.
- 6. A method of operating a wireless communication device which is compatible with a plurality of communication systems operable independently of each other under different communication protocols, the method comprising:checking, when a call is received through one communication system, whether the communication device is in communication through another communication system; reading out a fixed message from a memory in response to a check result indicating a communication through the another communication system; outputting an indication of a reception of the call from the one communication system; and transmitting the fixed message to the one communication system through one communication part of the communication device operable with a same protocol as that of the one communication system.
- 7. A method of claim 6, further comprising:checking whether a predetermined key operation on the communication device is made in response to the indication of the reception of the call; and enabling a transmission of the fixed message only when the predetermined key operation is detected.
- 8. A method of claim 6, further comprising:checking whether a predetermined key operation on the communication device is made in response to the indication of the reception of the call; and switching a connection of the communication device from the another communication system to the one communication device for communication through the one communication system.
