Abstract
Abstract A switching center (30) comprises a memory part (M2), a memory part (M3), and a memory part (M4). The memory part (M2) stores a terminating terminal number corresponding to each subscriber. The terminating terminal number is registered by each subscriber. The memory part (M3) stores idle/busy information corresponding to each terminal. The memory part (M4) stores idle/busy information corresponding to each subscriber. When a subscriber (11₁) makes a call at a terminal (12₂), the switching center (30) determines whether the idle/busy information for the subscriber (11₁) stored in the memory part (M4) is idle or busy. When the idle/busy information represents idle, the switching center (30) refers to the idle/busy information for the terminal (12₂) stored in the memory part (M3). When this idle/busy information represents idle, the switching center (30) interrogates the terminal number of a terminating terminal of a terminating subscriber stored in the terminating terminal memory part (M2) and performs an outgoing call connection process. At this point, the switching center (30) also sets the idle/busy information for the subscriber (11₁) and the terminal (12₂) to busy state. When the subscriber (11₁) makes a call, while the terminating terminal (12₁) is performing an incoming call connection process for the subscriber (11₁), since the idle/busy information for the subscriber (11₁) has been set to the busy state, even if the terminal (12₂) is idle, the switching center (30) does not perform an outgoing call connection process for the subscriber (11₁) at the terminal (12₂).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
240 words
A call connection method for a personal communication system including a plurality of switching centers and a plurality of terminals, each of said switching centers having subscriber idle/busy memory means and terminal idle/busy memory means, said subscriber idle/busy memory means being adapted for storing subscriber idle/busy information corresponding to the personal number of each subscriber, said terminal idle/busy memory means being adapted for storing terminal idle/busy information corresponding to the terminal number of each terminal, said method comprising the steps of: (A) receiving a terminating personal number and an originating personal number as an outgoing call connection request signal from an originating terminal; (B) interrogating idle/busy information corresponding to said originating personal number from said subscriber idle/busy memory means so as to determine whether the originating subscriber is idle or busy; (C) interrogating idle/busy information corresponding to the terminal number of said originating terminal so as to determine whether said originating terminal is idle or busy; (D) performing a connection process corresponding to said outgoing call connection request when both the determined results of said steps (B) and (C) are idle, and cancelling said connection process when at least one of the determined results of said steps (B) and (C) is busy; and (E) registering a busy state to said subscriber idle/busy memory means and said terminal idle/busy memory means corresponding to said originating subscriber and said originating terminal when said connection process has been performed in said step (D).
Claim 2
Dependent Claim
253 words
A call connection method for a personal communication system including a plurality of switching centers and a plurality of terminals, each of said switching centers having subscriber idle/busy memory means, terminal idle/busy memory means, and terminating terminal memory means, said subscriber idle/busy memory means being adapted for storing subscriber idle/busy information corresponding to the personal number of each subscriber, said terminal idle/busy memory means being adapted for storing terminal idle/busy information corresponding to the terminal number of each terminal, said terminating terminal memory means being adapted for storing a terminating terminal number corresponding to a personal number of said subscriber, said terminating terminal number being registered by said subscriber, said method comprising the steps of: (A) receiving a terminating personal number as an incoming call connection request signal; (B) interrogating idle/busy information corresponding to the terminating personal number from said subscriber idle/busy memory means so as to determine whether said terminating subscriber is idle or busy; (C) interrogating a terminating terminal number corresponding to the terminating personal number from said terminating terminal memory means; (D) interrogating idle/busy information corresponding to the terminating terminal number from said terminal idle/busy memory means so as to determine whether the terminating terminal is idle or busy; and (E) performing an incoming call connection process corresponding to the incoming call connection request when both the determined results of said steps (B) and (D) are idle, and cancelling the incoming call connection process when at least one of the determined results of said steps (B) and (D) is busy.
