Description

  The present invention relates to a mobile communication system that transmits and receives signals between a radio base station and a mobile communication terminal such as a mobile phone via a radio line.

  Mobile communication terminal devices such as mobile phones are rapidly becoming popular because they have the advantage of being able to talk on the move and in places where there is no public phone, but on the other hand, As a result, problems of ensuring user safety and public manners are occurring.

  For example, when using public transportation such as a train, the ring tone is perceived as an annoying sound for the surrounding people, which is not preferable in terms of manners. Therefore, a manner mode is provided in order to prevent a ring tone from being generated even if an incoming call is desired, and is set so as to notify the user by vibration or the like when the incoming call is received.

  However, in practice, when the user goes on the train with the mobile phone in a bag or handbag, the setting for switching to the manner mode tends to be neglected. For this reason, although it was a useful function, it was the actual situation that it was not utilized effectively. In view of this, mobile phones have been proposed that do not require a manner mode setting operation when traveling on a train or the like.

As such a mobile phone, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2003-204577) discloses timing information that accelerates the transmission timing to be transmitted from the mobile wireless terminal device to the base station according to the distance from the base station. Is received from at least three base stations, the moving speed is obtained based on the time and the radio wave propagation speed indicated by the received three types of timing information, and the operation state of the portable wireless terminal device is set to the manner mode accordingly. A portable wireless terminal device for switching is disclosed.

The processes of the position information acquisition unit and the movement speed information calculation unit are continuously executed in the background as long as the mobile communication terminal 100b is powered on. The position information acquired by the position information acquisition unit and the movement speed information acquired by the movement speed information calculation unit are logged retroactively for a predetermined time from the latest one.

  As described above, the position information acquired by the position information acquisition unit on the mobile communication terminal 100b side and the movement speed information calculated by the movement speed information calculation unit on the mobile communication terminal 100b side are transmitted to the radio base station. Since it becomes such a structure, it becomes possible to process, without burdening the base station control apparatus 300 side, such as log | history preservation | save load.

  In FIG. 5, the process is started in step S100 on the mobile communication terminal 100a side. In the subsequent step S101, when the user of the mobile communication terminal 100a activates the address book function, it is next determined in step S102 whether or not there is a registrant who can inquire about the status information in the address book. .

  Here, the address book function in the mobile communication terminal 100a is a function for registering the name, telephone number, and mail address of the owner of the mobile communication terminal of the other party that the mobile communication terminal 100a frequently sends. is there.

  In addition, since the service for notifying the mobile communication terminal 100a of the status information of the mobile communication terminal 100b according to the present embodiment relates to the privacy of the owner of the mobile communication terminal 100b, the service is moved by the owner. The registration system is based on the consent that the state information may be notified to the body communication terminal 100a. That is, according to the present embodiment, the status information of the owner of the mobile communication terminal 100b is controlled so as to be transmitted only to a predetermined mobile communication terminal. Only the status information of the mobile communication terminal holder is provided, and privacy is protected.

  When the determination result in step S102 is NO, the process proceeds to step S118. In step S118, a normal address book screen is displayed on display 115, and the process proceeds to step S119 to end the process.

In subsequent step S202, the map database unit 301 is collated with these pieces of information.

  In step S203, it is determined whether (position information) = (building position). The building position is based on data in the map database unit 301. When the determination result in step S203 is YES, the process proceeds to step S209, and the state of the owner of the mobile communication terminal 100b is determined to be in the building. Proceed to step S210 and return.

  When the determination result of step S203 is NO, the process proceeds to step S204. In step S204, it is determined whether (movement speed)> (predetermined speed or more).

  When the determination result in step S204 is NO, the process proceeds to step S208. In step S208, it is determined that the owner of the mobile communication terminal 100b is moving by walking. Proceed to step S210 and return.

  When the determination result in step S205 is YES, the process proceeds to step S205. In step S205, it is determined whether (position information) = (on the track). The position of the track is based on the data in the map database unit 301.

  When the determination result in step S204 is YES, the process proceeds to step S206. In step S206, it is determined that the owner of the mobile communication terminal 100b is moving by train. Proceed to step S210 and return.

  When the determination result in step S204 is NO, the process proceeds to step S207. In step S207, it is determined that the owner of the mobile communication terminal 100b is moving by a vehicle traveling on the road. Proceed to step S210 and return.

  As described above, according to the subroutine of the state determination process of the mobile communication system according to the present embodiment, whether the mobile communication terminal holder is in a building or is moving by a vehicle. It is possible to determine whether the vehicle is moving by train or is moving by walking.
