摘要： When a call of personal communication at a communication number PID arrives at an exchange (20), the exchange (20) fetches the user information UK corresponding to the number PID and call registration communication terminal identification number SID from a data base (30) and transmits the number PID to a communication terminal (10) (step S3). Upon receiving the response from the terminal (10), the exchange (20) generates a random number R (step S7) and sends the number R to the terminal (10) and, at the same time, generates a secret key K=F(R, UK) from the information UK and the number R (step S10). The terminal (10) generates the secret key K=F(R, UK) from the received number R and the information UK inputted by the user (step 9). The exchange (20) and terminal (10) transmit secreted communication information to each other by using the same secret key K and release the secrecy of the received secret communication information.

摘要： A mobile communications system including a voice message function in both a communications network (10) and a mobile station (20). If the mobile station (20) does not respond, the communications network responds instead thereof, stores a message, and notifies the mobile station of the presence of the message. The mobile station requests the transfer of the message when accessible. The message can be positively sent to a mobile station even if it is not accessible for a long time.

摘要： A mobile telephone location register ML and a subscriber location register SL are provided in a mobile communication network. In the mobile location register ML, the zonal position of the mobile telephone MT being in a zone is registered. In the subscriber location register SL, the mobile telephone MT which a subscriber SB selects as a receiving terminal is registered. When receiving a call to a subscriber, a switching station SW reads out from the subscriber location register SL the identification number TID of the mobile telephone which the subscriber registers as the receiving terminal. By using the mobile telephone identification number TID, the station reads out from the mobile telephone location register ML the position of the mobile telephone MT, and transmits the call to the mobile telephone registered as a receiving terminal in the zonal position.

The terminal (10) generates the secret key K=F(R, UK) from the received number R and the information UK inputted by the user (step 9). The exchange (20) and terminal (10) transmit secreted communication information to each other by using the same secret key K and release the secrecy of the received secret communication information.
