Abstract
Abstract A concordance table for a subscriber's number allotted to a subscriber, an equipment number allotted to a telephone set and a subscriber's line number allotted to a telephone connection terminal of the network is held in a memory circuit in the network, so that a calling can be received by the telephone set at his own subscriber's number wherever the subscriber or the telephone set moves. This table makes it possible to find out concordance of the equipment number of the telephone set registered corresponding to the subscriber's number with the subscriber's line number to which the equipment is now connected. When the connection is requested based on the subscriber's number, the table makes it possible to find out subscriber's line number to which is presently connected the telephone set that is registered for the subscriber's number, whereby connection is made to the telephone set that is registered for the subscriber's number. Equipment numbers have been regulated depend ing upon the manufacture or sales of the telephone sets so as not to be overlapped.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
151 words
A personal communication system having a public telephone network wherein a subscriber is assigned a personal telephone number, a telephone is recorded with a station number in a mode readable as signals, a subscriber loop of the network is assigned a subscriber loop address and the subscriber loop or a terminal connected thereto is provided with a connection terminal for connection with said telephone, which is characterized in that the public telephone network is further provided with a memory circuit which has a reference table of personal telephone numbers, station numbers registered under respective personal telephone numbers, and the subscriber loop addresses at which the registered telephones are being connected, a connection controller which connects a call with said currently connected subscriber loop address when a call for a personal telephone number is generated by referring to said table, and a registration means which writes in or modifies said reference table.
Claim 2
Dependent Claim
48 words
The personal communication system as claimed in Claim 1 wherein said connection controller includes a means which reads out the station number of a telephone connected to the connection terminal of the subscriber loop address in accordance with the call and collates the number with said reference table.
Claim 3
Dependent Claim
23 words
The personal communication system as claimed in Claim 1 wherein said telephone is a terminal device having other functions than a telephone call.
Claim 4
Dependent Claim
37 words
The personal communication system as claimed in Claim 1 wherein the station number is recorded fixedly on the telephone either in the order of manufacture or distribution according to a certain rule in order to avoid duplication.

Claim 7
Dependent Claim
68 words
The personal communication system as claimed in Claim 1 wherein said registration means includes a means which is actuated when a special number allocated for registration is dialed from a telephone connected to said terminal and reads the station number recorded therein, and a means which records in said reference table the station number thus read out by said means in correspondence with an appropriate personal telephone number.
Claim 8
Dependent Claim
37 words
The personal communication system as claimed in Claim 7 wherein said personal telephone number to be registered is the subscriber loop address of said connection terminal to which the telephone having the dialed special number is connected.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
59 words
The personal communication system as claimed in Claim 7 wherein an ID number is recorded in said reference table in correspondence with the personal telephone number thereof, and said registration means actuates said recording means only when the number inputted from the telephone connected to said terminal is collated with the corresponding ID number in reference to said table.
Claim 11
Dependent Claim
79 words
The personal communication system as claimed in Claim 7 wherein said registration means includes a means which is actuated when a special number allocated for specifying other positions is dialed from a telephone connected to said terminal to read the station number recorded in the telephone, and a means which records the subscriber loop address of the terminal in said reference table in correspondence with the personal telephone number corresponding to thus read out station number by said means.
