Abstract

An emergency wireless connection system which operates as a normal information terminal in normal times and operates as a terminal to send and receive emergency information in emergency situation includes a line detection unit which detects an emergency communication network capable of communicating when emergency situation occurs, and a control unit which makes the emergency wireless connection system conform to a procedure of the emergency communication network based on channel information of the emergency communication network detected by the line detection unit.

Claims

1. An emergency wireless connection system which operates as a normal information terminal in normal times and operates as a terminal to send and receive emergency information in emergency situation, comprising:

a line detection unit which detects a channel information from an emergency communication network with which frequency and a communication method are different by using in order a plurality of frequency set up in advance, when an emergency situation occurs; and

a control unit which analyzes the channel information on the emergency network detected by the line detection unit, and fits a transceiver function and an antenna circuit of a self-opportunity to the communication method of the emergency wireless connection system by reading a modulation and demodulation method and a connection protocol of the emergency wireless connection system based on the analysis result of the channel information.

2. The emergency wireless connection system according to claim 1, further comprising

an occurrence-of-emergency input unit which makes the information terminal recognize occurrence of the emergency situation.

3. The emergency wireless connection system according to claim 2, wherein,

the control unit performs line connection to the emergency communication network when the emergency wireless connection system is located outside a communication area of a normal communication network used in the normal times and an instruction of occurrence of the emergency situation is inputted by the occurrence-of-emergency input unit.

4. The emergency wireless connection system according to claim 2 wherein,

the control unit performs automatic transmission of information of the emergency wireless connection system to a communication partner registered in advance using the normal communication network when the emergency wireless connection system is located in a communication area of a normal communication network used in the normal times and an instruction of occurrence of the emergency situation is inputted by the occurrence-of-emergency input unit.

5. The emergency wireless connection system according to claim 2, wherein,

the control unit performs automatic transmission of information of the emergency wireless connection system to a communication partner registered in advance using the emergency communication network when the emergency wireless connection system is located outside a communication area of a normal communication network used in the normal times and an instruction of occurrence of the emergency situation is inputted by the occurrence-of-emergency input unit.

6. An emergency wireless connection method for operating as a normal information terminal in normal times and operating as a terminal to send and receive emergency information in emergency situation, comprising:

a line detection procedure for detecting a channel information from an emergency communication network with which frequency and a communication method are different by using in order a plurality of frequency set up in advance, when an emergency situation occurs; and

a control procedure for analyzing the channel information on the emergency communication network detected by the line detection procedure, and fits a transceiver function and an antenna circuit of a self-opportunity to the communication method of the emergency wireless connection system by reading a modulation and demodulation method and a connection protocol of the emergency wireless connection system based on the analysis result of the channel information.

7. The emergency wireless connection method according to claim 6, wherein

the control procedure comprises a procedure for performing line connection to the emergency communication network when the emergency wireless connection system is located outside a communication area of a normal communication network used in a normal times and an instruction of occurrence of the emergency situation is inputted by an occurrence-of-emergency input unit.

8. The emergency wireless connection method according to claim 7, wherein

the control procedure comprises a procedure for performing automatic transmission of information of the emergency wireless connection system to a communication partner registered in advance using the normal communication network when the emergency wireless connection system is located in a communication area of a normal communication network used in a normal times and an instruction of occurrence of the emergency situation is inputted by the occurrence-of-emergency input unit.

9. The emergency wireless connection method according to claim 7, wherein

the control procedure comprises a procedure for performing automatic transmission of information of the emergency wireless connection system to a communication partner registered in advance using the emergency communication network when the emergency wireless connection system is located outside a communication area of a normal communication network used in a normal times and an instruction of occurrence of the emergency situation is inputted by the occurrence-of-emergency input unit.
