ABSTRACT:
A communication system includes: a server for transmitting a connection request to a cellular phone through a cellular phone network when receiving the connection request from a communication station to the cellular phone; the cellular phone for establishing a Bluetooth communication channel between the cellular phone and a hot spot computer located around the cellular phone in response to the connection request received from the server; and the hot spot computer for transmitting data received from the cellular phone to the server through a network via the Bluetooth communication channel so as to communicate the cellular phone with the communication station. When the communication channel between the cellular phone and the hot spot computer cannot be established, the cellular phone transmits information which represents a reason that the communication channel cannot be established, to the communication station through the server.
