Description
This application is a divisional of U.S. patent application Ser. No. 08/132,355, filed Oct. 6, 1996 (now abandoned).
In a personal communication, when a subscriber makes a call, he inputs into a terminal both his personal number and a terminating personal number or a terminating terminal number. Thus, an outgoing call connection request takes place. The terminal sends this request to the switching center connected thereto. The switching center interrogates a service class of the subscriber corresponding to the received originating personal number from a subscriber service memory part M1. (The term "interrogate" means, throughout this specification, "retrieve and read out".) Thereafter, the switching center starts an outgoing call connection process corresponding to the service class. For example, when the subscriber 111 makes a call at the terminal 122, the switching center 301 refers to the idle/busy information for the terminal 122 stored in the terminal idle/busy memory part M3. When the idle/busy information represents an idle state, the switching center 301 performs the outgoing call connection process. Since the terminal 122 is a terminating terminal of the subscriber 112, if the switching center 301 is performing a terminating call process to the subscriber 112 and therefore his idle/busy state is busy when the subscriber 111 makes a call at the terminal 122, the switching center 301 does not perform the originating process for the subscriber 111.
In an integrated services digital network (ISDN) system, which is not necessarily a personal communication system, each terminating terminal has a display 12D as shown in FIG. 1. With the display 12D, a calling line identification service which displays the terminal number of an originating terminal is performed. In this system, each switching center 30 shown in FIG. 1 comprises, as shown in FIG. 2, a call connection control part 31, a terminal number sending/receiving part 34, a terminal number transmitting part 35, and a personal number receiving part 36. The call connection control part 31 controls line connections between the switching center and terminals or line connection with another switching center. The terminal number sending/receiving part 34 sends and receives terminal numbers to and from terminal 121. The terminal number transmitting part 35 sends and receives a terminal number to and from another switching center. The personal number receiving part 36 receives personal numbers from terminals 12j.
When a call is sent from a telephone with a representative telephone number of a company or the like, it is impossible for a terminating subscriber to know by whom of the company the call is sent. When a call is sent from a mobile telephone (such as a car telephone or a portable cellular phone), if the mobile telephone is shared by several people, it is impossible for a terminating subscriber to know by whom the call is sent. In the personal communication (personal number communication) system, each subscriber is given a unique personal number and any terminal can be registered as his terminating terminal. Even if the calling line identification service of the ISDN system is introduced to the personal communication system, the terminating subscriber cannot know the originating subscriber from the originating terminal number since each terminal can be used by any subscriber. Thus, even with the terminal number of an originating terminal displayed on the terminating terminal, the terminating subscriber cannot estimate the identify of the originating subscriber. In other words, although each subscriber is given a unique personal number, it cannot be effectively used.
