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. By transmitting the obtained location data from each mobile phone to the location information service center via the base station, the location data of the mobile phone is held in a server (database) in the location information service center, and the location information is stored in another mobile phone. There is a location-based service that can access the database from the phone.

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 a location information service, and the location data is transmitted from the mobile phone B to a location information service center via a base station. In the location information service center,
The position data and an ID indicating the position data of the mobile phone B are held.

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 a password to the user of the mobile phone A, the user of the mobile phone A can obtain the location information of the mobile phone B from the location information service center by inputting the password. Can be. However, if the user of the mobile phone A does not know the password, the location information of the mobile phone B cannot be obtained from the location information service center.

[0005] Thus, if you do not give the password,
Your location is not known to others and your privacy is protected.

[0006]

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 access the location information service center to obtain location information.
Therefore, 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 own 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.

However, if the mobile phone A does not register the mobile phone A in the location information unrecognizable list (step 305), the mobile phone A accesses the location information service center and checks the location of the mobile phone B as usual. (Step 307).

Next, it is assumed that the mobile phone A makes an inquiry about the location information of the mobile phone B (step 30).
8). At this time, for example, the mobile phone A sends the location information service center the telephone number of the mobile phone B whose location information is to be confirmed, the telephone number of the mobile phone A, and the password for confirming the location information of the mobile phone B. Send. But,
The data transmitted from the mobile phone A to the location information service center includes data for identifying that the other party to be located is the mobile phone B, data for confirming the transmission from the mobile phone A, and the above password. Any form of data may be transmitted as long as the data is transmitted.

Next, when the location information service center recognizes that it is an inquiry from the mobile phone A for the location information of the mobile phone B, it checks whether the mobile phone A is registered in the location unrecognizable list of the mobile phone B. It is confirmed whether or not it is (Step 309). At this time, it is also checked whether the password is correct, but such a method is publicly known and is not shown in FIG.

If the location information service center does not register the mobile phone A in the location confirmation list of the mobile phone B (step 309), the location information service center sends the location information of the mobile phone B to the mobile phone A. Transmit (step 312). Therefore, the mobile phone A can receive the location information of the mobile phone B and confirm the location of the mobile phone B (step 313).

On the other hand, if the mobile phone A is registered in the location unrecognizable list of the mobile phone B at the location information service center (step 309), the location information service center does not check the location of the mobile phone B. A message indicating the possibility is transmitted to the mobile phone A (step 310). When the mobile phone A receives a message indicating that such a position check is not possible, the mobile phone A cannot check the position of the mobile phone B, and the received message is displayed on the display unit. Display (Step 311) Next, FIG. 5 shows a flowchart in the second embodiment of the system of the present invention. The default is to turn on location services. Therefore, in step 501, the mobile phone B turns on the location information service, accesses the GPS satellites, and acquires GPS location data via the GPS antenna (12) and the GPS processing unit (11). Next, step 50

However, if the user of the mobile phone B does not want the user of the mobile phone A to know his / her position during a certain time zone (step 504), the user sets the timer of the mobile phone B for that time zone. Perform (step 505). The mobile phone A registers the mobile phone A in the location unrecognizable list. (Step 506). At this time, for example, as shown in FIG. 4, the position confirmation impossible list may simply list up the mobile phones of the users who do not want to give the position. However, the method of registering in the position unrecognizable list is not limited to this method, and any method may be used as long as a method can be used to specify a partner whose position is not desired to be confirmed. Further, the position confirmation non-executable list created here may be separately created in a time zone set by the timer.

Next, when the time set by the timer has come (step 507), the location confirmation impossible list created in step 506 is transmitted to the location information service center (step 508). At this time, the determination may be made based on whether or not a predetermined time (for example, 5 minutes before) comes before the time set by the timer in step 507.

However, if the time is not the time set by the timer (step 507), the position confirmation impossible list is not transmitted, or if the time period set by the timer has passed, the mobile phone B will use the position information service. In order to invalidate the location unrecognizable list held in the center (step 509), the mobile phone A can access the location information service center and check the location of the mobile phone B as usual (step 509). Step 510).
At this time, the determination may be made based on whether or not a predetermined time (for example, 5 minutes before) comes before the time set by the timer in step 507.

Next, it is assumed that the mobile phone A makes an inquiry about the location information of the mobile phone B (step 51).

Next, step 60
In 2, the mobile phone B transmits the acquired GPS position data to the position information service center via the transmission unit (5), the duplexer (3), and the antenna (1). In this way, the location information service center acquires the GPS location data of the mobile phone B, and when it is held, the mobile phone B, which is another mobile phone,
It is possible to access the location information service center from A and confirm the location of the mobile phone B (step 6).
03). The processing up to this point is intermittently repeated when the operation after step 604 is not performed.

However, if the user of the mobile phone B does not want the user of the mobile phone A to know his / her position in a certain time zone (step 604), the user sets the timer of the mobile phone B for the certain time zone. Determine whether to do it. (Step 605). If you want to set the timer, step 6
At 06, a timer is set. When the time set by the timer comes, the mobile phone B stops the GPS function (step 607).

Next, when the timer is not set (step 605), the GPS data is intermittently acquired as usual and transmitted to the location information service center as described above.

Next, it is assumed that the mobile phone A makes an inquiry about the location information of the mobile phone B (step 60).
8). At this time, for example, the mobile phone A sends the location information service center the telephone number of the mobile phone B whose location information is to be confirmed, the telephone number of the mobile phone A, and the password for confirming the location information of the mobile phone B. Send. But,
The data transmitted from the mobile phone A to the location information service center includes data for identifying that the other party to be located is the mobile phone B, data for confirming the transmission from the mobile phone A, and the above password. Any form of data may be transmitted as long as the data is transmitted.

Next, the location information service center, when recognizing that it is an inquiry of the location information of the mobile phone B from the mobile phone A, updates the location data in the mobile phone B within a fixed time in the past (for example, 5 minutes). It is confirmed whether or not it has been performed (step 609). At this time, it is also confirmed whether the password is correct, but such a method is publicly known and is not shown in FIG.

At the location information service center, the location data of the mobile phone B is stored within a certain period of time in the past (for example, 5 minutes).
