Emergency report cellular phone, cellular connection switching method and GPS positioning method

An emergency report cellular phone, comprising:

• a system controller containing a siren intermittent drive section for intermittently driving a siren, and a communications enable signal generating section, which, on the basis of an intermittent siren drive signal, outputs a communications enable signal;
• a memory, which stores information for connections;
• a cellular transceiver section, which connects to a cellular system to transmit and receive data and/or voice signals;
• a voice processing section, which contains a DTMF encoder for data communications and which is for voice communications with the emergency report center via said cellular system;
• a DTMF decoder, which decodes DTMF signals transmitted from the emergency report center and then outputs the decoded result to said system controller;
• a speaker and a microphone, which are connected with said voice processing section;
• and a siren, which is driven by the intermittent siren drive signal and which performs notification of a state of emergency to the surrounding area;
• wherein, even in a state in which the siren function is ON on the basis of said communications enable signal, said emergency report cellular phone performs data communications at a time when said siren is not being driven.

An emergency report cellular phone, comprising:

• a system controller, which contains a connection system switching section for connecting to a plurality of cellular systems;
• a memory, which stores information for connections;
• a cellular transceiver section, which connects to a cellular system to transmit and receive data and/or voice signals;
• a voice processing section, which contains a DTMF encoder for data communications by means of DTMF signals, and which is for voice communications with an emergency report center via said cellular systems;
• a DTMF decoder, which decodes DTMF signals transmitted from said emergency report center and then outputs the decoded result to said system controller;
• a microphone and a speaker, which are connected with said voice processing section;
• a siren, which performs notification of a state of emergency;
• and a timer for judging processing time out, wherein said memory stores system A connection information, system B connection information, and a maximum connection frequency, and said connection system switching section uses a system A and a system B on the basis of the content of said memory and the output of said timer and following a predetermined procedure such that while the connection system switching section performs connection processing with respect to a preset first telephone number, when connection with respect to said first telephone number is not possible, same performs connection processing with respect to a preset second telephone number, wherein said connection system switching section sets systems for connection as preset systems;
• on the basis of the system A connection information or system B connection information stored in said memory, connects to said first telephone number or said second telephone number;
• activates said timer;
• according to whether a user identification request signal is received, judges whether or not a connection has been established;
• on the basis of the output of said timer, judges whether or not time out is effected;
• and, when the time out judgement frequency is no more than the maximum connection frequency stored in said memory, switches the system for connection, and once more repeats the connection with respect to said first telephone number or said second telephone number.

• on the basis of the system A connection information or said system B connection information stored in said memory, connects to said first telephone number or said second telephone number;
• sets a start channel of a control channel search;
• judges whether or not connection is possible in accordance with the existence or non-existence of a control channel;
• judges whether or not a final channel of a control channel search has been reached;
• and, when the frequency of judging whether or not the final channel has been reached is no more than the maximum connection frequency stored in said memory, switches the system for connection, and once more repeats the connection with respect to said first telephone number or said second telephone number.
