Emergency call code information acquiring system
View Patent ↗A mobile communication base station transmits broadcast information containing emergency call code information to a mobile terminal with the status “Camped on any cell” defined in the 3GPP specification “TS25.304”. Upon receiving the broadcast information, the mobile terminal acquires emergency call code information from the broadcast information. The status “Camped on any cell” means that a status in which an IC card is uninserted and the mobile terminal is communicable with the mobile communication base station from the perspective of radio wave strength or a status in which an IC card is inserted, the mobile terminal is communicable with the mobile communication base station from the perspective of radio wave strength, and an Attach or location registration to an MSC via the mobile communication base station and an RNC fails.
1. An emergency call code information acquiring system, comprising:
a mobile communication base station that transmits broadcast information that is information to be broadcasted as a service; and
a terminal device that receives the broadcast information that is autonomously transmitted from the mobile communication base station for a specified period when a power switch of the mobile communication base station is turned on and can be received by the terminal device in a first status and a second status, wherein
the mobile communication base station comprises a transmitting unit that transmits broadcast information including emergency call code information that is information about a call number of an emergency agency, to the terminal device that is either in the first status in which an IC card is uninserted and the terminal device is communicable with the mobile communication base station from the perspective of radio wave strength or in the second status in which the IC card is inserted, the terminal device is communicable with the mobile communication base station from the perspective of radio wave strength, and an Attach or location registration to an Mobile-services Switching Centre MSC via the mobile communication base station and an Radio Network Controller RNC fails, and
the terminal device comprises an emergency call code information acquiring unit that acquires, when the terminal device receives the broadcast information transmitted by the transmitting unit of the mobile communication base station in either the first status or the second status, the emergency call code information included in the received broadcast information, and
a call processing unit that collates the emergency call code information acquired by the emergency call code information acquiring unit with the emergency call code information read from the IC card, and when the acquired emergency call code information is identical with the read emergency call code information, calls the number indicated by the emergency call code information.
2. A mobile communication base station, comprising a transmitting unit that transmits broadcast information that is autonomously transmitted from the mobile communication base station for a specified period when a power switch of the mobile communication base station is turned on and can be received by a terminal device in a first status and a second status, including emergency call code information that is information about a call number of an emergency agency, to the terminal device that is either in the first status in which an IC card is uninserted and the terminal device is communicable with the mobile communication base station from the perspective of radio wave strength or in the second status in which the IC card is inserted, the terminal device is communicable with the mobile communication base station from the perspective of radio wave strength, and an Attach or location registration to an Mobile-services Switching Centre MSC via the mobile communication base station and an Radio Network Controller RNC fails, wherein
the terminal device comprises a call processing unit that collates the emergency call code information acquired by an emergency call code information acquiring unit with the emergency call code information read from the IC card, and when the acquired emergency call code information is identical with the read emergency call code information, calls the number indicated by the emergency call code information.
3. A terminal device, comprising an emergency call code information acquiring unit that acquires, when the terminal device receives broadcast information that is autonomously transmitted from a mobile communication base station for a specified period when a power switch of the mobile communication base station is turned on and can be received by the terminal device in a first status and a second status, transmitted by the mobile communication base station either in the first status in which an IC card is uninserted and the terminal device is communicable with the mobile communication base-station device from the perspective of radio wave strength or in the second status in which the IC card is inserted, the terminal device is communicable with the mobile communication base-station device from the perspective of radio wave strength, and an Attach or location registration to an Mobile-services Switching Centre MSC via the mobile communication base station and an Radio Network Controller RNC fails, emergency call code information included in the received broadcast information, and
a call processing unit that collates the emergency call code information acquired by the emergency call code information acquiring unit with the emergency call code information read from the IC card, and when the acquired emergency call code information is identical with the read emergency call code information, calls the number indicated by the emergency call code information.
4. An emergency call code information acquiring method, comprising:
transmitting broadcast information that is autonomously transmitted from a mobile communication base station for a specified period when a power switch of the mobile communication base station is turned on and can be received by a terminal device in a first status and a second status, including emergency call code information to the terminal device that is either in the first status in which an IC card is uninserted and the terminal device is communicable with the mobile communication base station from the perspective of radio wave strength or in the second status in which the IC card is inserted, the terminal device is communicable with the mobile communication base station from the perspective of radio wave strength, and an Attach or location registration to an Mobile-services Switching Centre MSC via the mobile communication base station and an Radio Network Controller RNC fails;
acquiring, when the terminal device receives broadcast information transmitted at the transmitting in either the first status or the second status, the emergency call code information included in the received broadcast information; and
collating the emergency call code information acquired at the acquiring with the emergency call code information read from the IC card, and when the acquired emergency call code information is identical with the read emergency call code information, calling the number indicated by the emergency call code information.
