摘要:
In a mobile communication system including a plurality of mobile switching centers (4, 5), a plurality of base stations (2, 3) each having an independent radio zone area (12, 13) and multi-connecting device (16) in the mobile switching center (4, 5) the process of switching a radio speech channel during communication comprises detecting a radio speech channel in the destination radio zone area, multi-connecting by the multi-connecting device (16) wire speech paths through the mobile switching centers (4, 5), switching the radio speech channel to be used by the mobile station (1) from the radio speech channel in the old zone area to the radio speech channel in the new zone area to the radio channel in the new zone area while keeping the communication condition of the mobile station (1).
摘要:
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).
