Abstract:
1. A system for managing telephone service for a plurality of persons sharing a common telephone line based on determining whether a person sharing the common telephone line is at the location served by the common telephone line and for restricting completion of a telephone call from the common telephone line to permit said telephone call to be completed only when a required person is present at the location served by the common telephone line, comprising: a transmitter accompanying the person and periodically emitting a unique signal; a base station serving each person sharing the common telephone line at the location served by the common telephone line and containing a receiver; said base station further containing a processor; a base station database containing at least one unique record, said unique record corresponding to said person and correlating said unique signal emitted by said transmitter to said unique record in said base station database; the base station processor being arranged to make an entry in the base station database record that corresponds to said transmitter, recording a receipt of said unique signal; the base station processor being arranged to make an entry in the base station database record that corresponds to said transmitter, recording a failure to receive said signal for a predetermined period of time; whereby the base station database maintains a record for each person sharing the common telephone line indicating whether that person is or is not at the location served by the common telephone line; a telephone connection from the base station over the common telephone line to a local telephone network controller located in the telephone network providing telephone service to the common telephone line; a network database maintained by said local telephone network controller, said network database containing a plurality of network database records; the base station processor being arranged, upon detecting a change in at least one of said records in said base station database indicating whether a person is or is not at the location served by the common telephone line, to initiate a telephone call over the common telephone line to said local telephone network controller, to upload said changed base station database into the network database, and thereafter to disconnect said telephone call, thereby updating said network database to indicate whether each of the persons sharing the common telephone line is or is not at the location served by the common telephone line; a database in the network controller of at least one subscriber telephone numbers including the subscriber telephone number associated with the common telephone line that have restrictions on outbound telephone calls; for each of said subscriber telephone numbers that have restrictions on outbound telephone calls including the subscriber telephone number associated with the common telephone line, a database list in the network controller of at least one restricted outbound telephone numbers associated with at least one of the persons sharing the common telephone line; a database in the base station of a list of at least one restricted outbound telephone numbers associated with at least one of the persons sharing the common telephone line; the base station processor being arranged, upon detecting a change in at least one of said records in said base station database of restricted outbound telephone numbers, to initiate a telephone call over the common telephone line to said local telephone network controller to upload said changed base station database list of restricted outbound telephone numbers into the network database, and thereafter to disconnect said telephone call, thereby to record in said network database an updated list of restricted outbound telephone numbers associated with persons sharing the common telephone line; the network controller being arranged, when an outbound telephone call from one of said subscriber telephone numbers is made to one of said restricted outbound telephone numbers, to check the network database to determine whether the outbound telephone call is from one of the subscriber telephone numbers that has restriction on outbound telephone calls; when an outbound telephone call from one of said subscriber telephone numbers is determined to be from one of the subscriber telephone numbers that has restrictions on outbound telephone calls, the network controller being arranged to check the updated list of restricted outbound telephone numbers to determine whether a number being called may be completed only if at least one required person is present; wherein, when it is determined that a number being called may be completed only if at least one required person is present, the network controller is arranged to check the updated network database to determine whether said at least one person is present; and the network controller being arranged to permit said restricted outbound telephone call to be completed only if said at least one required person is present.
