Camp-on communication managing method and apparatus

A camp-on communication managing apparatus comprising:

• a personal position registration table in which terminal identification information for identifying a communication terminal used by each subscriber is registered for each personal identification information for identifying a subscriber;
• a personal status registration table in which information indicating whether each subscriber is in a communication-possible state is registered for each said personal identification information;
• a personal camp-on registration table in which personal identification information of a calling-side subscriber who requests a camp-on operation and personal identification information of a call-receiving-side subscriber are to be registered;
• personal position managing means for referring, when receiving the personal identification information of the calling-side subscriber and the personal identification information of the call-receiving-side subscriber from the calling-side subscriber, to the personal position registration table based on the calling-side personal identification information and the call-receiving-side personal identification information, and for detecting calling-side terminal identification information and call-receiving-side terminal identification information;
• personal camp-on managing means for registering the calling-side personal identification information and terminal identification information and the call-receiving-side personal identification information and terminal identification information in the personal camp-on registration table;
• personal status managing means for monitoring a communication status of the call-receiving-side subscriber, and for rewriting communication status identification information of the personal status registration table when the communication state of the call-receiving-side subscriber has been made a status transition;
• and
• calling means for searching, when detecting that the call-receiving-side subscriber has made a status transition to a communication-possible state by referring to the personal status registration table, for information in the personal camp-on registration table based on the personal identification information of the call-receiving-side subscriber, reading out the terminal identification information of the call-receiving-side subscriber and the terminal identification information of the calling-side subscriber from the personal camp-on registration table, and calling the calling-side subscriber and the call-receiving-side subscriber based on the terminal identification information of the call-receiving-side subscriber and the calling-side subscriber.

An exchange for executing communication between subscribers according to personal identification information identifying each subscriber, the exchange comprising:

• receiving means for receiving a camp-on operation request from a calling subscriber when a called subscriber is in a communication-impossible state;
• camp-on setting means for setting camp-on operation between said calling subscriber and said called subscriber;
• and
• calling means for calling a communication terminal registered in a personal position registration table by said calling subscriber and a communication terminal registered in said personal position registration table by said called subscriber, when a communication state of said called subscriber changes to a communication-possible state and a communication state of said calling subscriber is a communication-possible state.

• receiving means for receiving a camp-on setting request from a calling subscriber, when a called subscriber is in a communication-impossible state;
• camp-on setting means for setting camp-on operation between said calling subscriber and said called subscriber;
• measuring means for measuring an elapsed time from when said camp-on setting means sets camp-on operation between said calling subscriber and said called subscriber;
• camp-on canceling means for canceling the camp-on setting, if a communication state of said called subscriber is not changed to a communication-possible state within a specified period;
• and
• calling means for calling the communication terminal of said calling subscriber and the communication terminal of said called subscriber, if the communication state of said called subscriber is changed to a communication-possible state within a specified period.

• camp-on setting means for setting camp-on operation between said calling subscriber and said called subscriber;
• and
• calling means for calling a communication terminal registered in a personal position registration table used by said calling subscriber and a communication terminal registered in said personal position registration table used by said called subscriber, when a communication state of said called subscriber is changed to a second communication state and said calling subscriber is in a second communication state.
