PROBLEM TO BE SOLVED: To continue a call by allowing the exchange for mobile communication to inform an opposite subscriber of a message including the added reason for disconnection and telephone call transfer and also to hold the line, and call the telephone number of a transfer destination that the mobile station has registered and connect the line if the mobile station quits a communication since it is difficult to communicate. SOLUTION: When the mobile station MS: 4 judges that it is difficult to communication, sends a disconnection message out to the exchange 1 for mobile communication, and quits the communication, a reason analysis part 20 of the exchange 1 for mobile communication analyzes the reason for the disconnection from the disconnection message and a state information part 21 adds the reason and informs the communication opposite terminal station 7 of telephone call transfer, and also holds the line. An HM readout part 22 calls the home memory HM: 3 of the subscriber and reads the transfer destination telephone number of another previously specified mobile station terminal 8 out of the HM: 3 and a line switching part 23 calls the mobile station terminal 8. When the terminal station answers, it is connected to the held line to allows the terminal station 7 to continue to communication with the transfer destination terminal station, thus eliminating the need for repetitive calling. |
