Abstract
The object of the present invention is to provide a cellular phone to be used for emergency reports that performs GPS positioning by means of remote control from an emergency report center, and transmits positional information to the emergency report center. The emergency report cellular phone according to the present invention is constituted such that when an emergency report switch thereof is depressed, a call request is made to the emergency report center. The emergency report center transmits a response signal with the result that a call link is formed between the emergency report cellular phone and the emergency report center. Following completion of the telephone call, the emergency report center transmits a position recalculation command message, by means of a DTMF signal. The emergency report cellular phone, which has received this command message, performs GPS positioning and then converts latitudinal and longitudinal information to a DTMF signal before transmitting same to the emergency report center. As a result, even in a case where, in a time of emergency, a reporting party is unable to perform GPS positioning manually as a result of a poor physical condition, for example, since GPS positioning is possible by means of remote control, it is possible to rescue the reporting party in a rapid and reliable manner.

85. A computer program product, for which a program for executing GPS positioning processing for a cellular phone is recorded on a computer-readable recording medium,
wherein said computer program is for the execution of steps comprising: -
storing satellite positional information for when GPS positioning was performed on a previous occasion;
capturing satellites by referencing said satellite positional information to perform GPS positioning on the basis of GPS signals from satellites, and, in a case where GPS positioning is completed within a fixed period, storing the latest satellite positional information in said storage section, and, in a case where GPS positioning is not completed within a fixed period, restoring the satellite positional information stored in said storage section to initial values; and
connecting to an emergency report center via a wireless line to make an emergency report and to transmit longitudinal and latitudinal information for a positioning point to the emergency report center. - View Dependent Claims (86, 87, 88)

89. A computer program product, for which a program for executing GPS positioning processing for an emergency report cellular phone is recorded on a computer-readable recording medium,
wherein said computer program is for the execution of steps comprising: -
storing satellite positional information for when GPS positioning was performed on a previous occasion;
capturing satellites by referencing said satellite positional information to perform GPS positioning on the basis of GPS signals from satellites, and, in a case where GPS positioning is completed within a fixed period, storing the latest satellite positional information in said storage section, and, in a case where GPS positioning is not completed within a fixed period and when the number of satellites captured is three or more, restoring the satellite positional information stored in said storage section to initial values, and when the number of satellites captured is two or less, outputting non-positioning information; and
connecting to an emergency report center via a wireless line to make an emergency report and to transmit longitudinal and latitudinal information for a positioning point to the emergency report center. - View Dependent Claims (90, 91, 92)

93. A computer program product, for which a program for executing GPS positioning processing for an emergency report cellular phone is recorded on a computer-readable recording medium,
wherein said computer program is for the execution of steps comprising: -
storing satellite positional information for when GPS positioning was performed on a previous occasion;
capturing satellites by referencing said satellite positional information to perform GPS positioning on the basis of GPS signals from satellites, and, in a case where GPS positioning is completed within a fixed period, storing the latest satellite positional information in said storage section, and, in a case where GPS positioning is not completed within a fixed period and when the number of satellites captured is four or more, reactivating a GPS positioning section, and when the number of satellites captured is three or less, restoring the satellite positional information stored in said storage section to initial values; and
connecting to an emergency report center via a wireless line to make an emergency report and to transmit longitudinal and latitudinal information for a positioning point to the emergency report center. - View Dependent Claims (94, 95, 96)

97. A computer program product, for which a program for checking the GPS positioning capability of an emergency report cellular phone is recorded on a computer-readable recording medium,
wherein said computer program is for the execution of steps comprising: -
on the basis of an instruction optionally given by a user at a time other than when an emergency report is being made, checking whether or not data communications between said GPS receiver and the wireless communications section are normal;
in a case where said data communications are normal, also checking whether or not the GPS receiver is capable of completing GPS positioning within a fixed period; and
,in a case where said data communications are not normal or said GPS positioning cannot be completed within a fixed period, issuing a warning to that effect. - View Dependent Claims (98, 99)
