Emergency call system and emergency call method

An emergency call method using a position information management device and a position information notification device, comprising the steps of:

• causing the position information management device to manage first terminal information of a terminal and first position information of the terminal;
• and
• causing the position information management device to receive the first terminal information transmitted from the first position information notification device and to transmit the first position information to the position information notification device;
• causing the position information notification device to manage the first terminal information and first address information of the position information management device;
• and
• causing the position information notification device to receive the first terminal information from the first terminal, to transmit the first terminal information to the position information management device on the basis of the first address information, to receive the first position information from the position information management device, and to transmit the first position information to a first device.

An emergency call system comprising:

• a position information management device;
• a call control device;
• and
• a position information notification device;
• wherein the position information management device includes:
• a first management section which manages the first terminal information of a terminal and the first position information of the terminal, and
• a first processing section which receives the first terminal information transmitted from the position information notification device, and transmits the first position information to the position information notification device;
• wherein the call control device retrieves the first terminal information from a received second terminal information of the terminal, and transmits the retrieved first terminal information;
• wherein the position information notification device includes:
• a second management section which manages the first terminal information and first address information of the position information management device, and
• a second processing section which receives the second terminal information from a command system placed in an emergency call receiving organization, transmits the second terminal information to the call control device, receives the first terminal information from the call control device, transmits the first terminal information to the position information management device on the basis of the first address information, receives the first position information from the position information management device, and transmits the first position information to a first device.

• and
• a first processing section which receives the first terminal information transmitted from the position information notification device, and transmits the first position information to the position information notification device;
• and
• wherein the position information notification device includes:
• a second management section which manages network address information of first address information of the position information management device, and the first address information of the position information management device;
• and
• a second processing section which receives first terminal information from a command system placed in an emergency call receiving organization, retrieves the network address information of the first address information which indicates with a network address of the first terminal information, transmits the first terminal information to the position information management device on the basis of the retrieved address information, receives the first position information from the position information management device, and transmits the first position information to a first device.

An emergency call method using a position information management device, a call control device, and a position information notification device, comprising the steps of:
