Abstract

PROBLEM TO BE SOLVED: To solve the problem that a conventional position information service employing a GPS-mounted portable communication unit where a user B of the GPS-mounted portable communication unit stores its own current position information acquired from the GPS, a user A knowing a password of the user B for position confirmation can confirm the current position of the user B, however the user A can confirm the current position of the user B at any time when the user B once informs the user A about its own password, and consequently the privacy cannot be protected. SOLUTION: The user B creates a position confirmation disable list and registers to the list a person (e.g. the user A) by whom the position of the user A is not desired to be confirmed. The mobile phone of the user B stores the position confirmation disable list and confirms whether or not the user A is registered in the position confirmation disable list when the mobile phone of the user A makes a request of position confirmation. When the user A is registered in the position confirmation disable list, the mobile phone of the user B transmits a message denoting disabled position confirmation to the user B.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio communication device using a satellite.

[0002]

2. Description of the Related Art A GPS-equipped mobile phone can receive a signal from a GPS satellite and obtain position, date, time data. When the location data is requested from another mobile phone in accordance with the location information service, the obtained location data is transmitted to the other party's mobile phone via the base station in response to a request from the location information service center. Therefore, there is a location information service in which the other party's mobile phone is notified of the current location.

FIG. 8 shows an outline of the location information service. The mobile phone B is equipped with GPS, and can communicate with GPS satellites to obtain data on its own location (eg, latitude and longitude). At this time, communication is normally performed with three GPS satellites, but FIG. 8 shows only one for simplicity. The location data obtained by the mobile phone B is used not only in the mobile phone B but also in accordance with the location information service, and the location data is requested from the mobile phone A to the location information service center via the base station. The information service center issues a request for transmitting position data to the mobile phone B in accordance with the request.
The mobile phone B that has received the position information transmission request from the position information service center sends the position data to the position information service center, and the position data is transmitted to the mobile phone A via the position information service center.

[0004] At this time, after receiving the position information transmission request from the position information service center, the mobile phone B receives the GP request.
There is also a method of acquiring the current position data by the S function and transmitting it to the position information center.

Next, when the location information of the mobile phone B is requested from the mobile phone A, usually, for privacy protection,
Mobile phone A is required for a password for mobile phone B. If the user of the mobile phone B has previously provided the password to the user of the mobile phone A, the user of the mobile phone A confirms the password on the mobile phone B by inputting the password, and the position data is stored. Sent via the information service center. However, if the user of the mobile phone A does not know the password, the mobile phone B refuses to transmit the position data.

As described above, if you do not give the password,
Your location is not known to others and your privacy is protected.

[0007]

There is a case where a password for a location information service is provided to a plurality of persons, and some or all of the persons do not want to know their positions. But,
Anyone who knows the password can always use the location information service to obtain location information. for that reason,
A person who knows the password can always confirm the position of the other party, and the conventional method cannot provide sufficient privacy protection.

Therefore, if the user does not want to know his / her position, the only option is to turn off the power. However, when the power is turned off, there is an inconvenience that a normal mobile phone cannot be used.
