Description

  The present invention relates to a traffic information providing system for a mobile terminal in a mobile communication system.

  In the conventional mobile communication system, when the mobile terminal is turned on, at the time of location registration, and at the time of outgoing / incoming standby after location registration, the mobile terminal receives information on the channel usage status transmitted from the radio exchange, By displaying the information on the display unit of the mobile terminal, the user using the mobile terminal can recognize the usage status of the base station and select a base station with less congestion (for example, see Patent Document 1). ).

JP 2000-224657 A (stages 0013 to 0016, FIG. 1)

  However, in the conventional mobile communication system, when the mobile terminal is turned on, at the time of location registration, and at the time of outgoing / incoming standby after location registration, only the channel usage status of the radio base station is notified to the mobile terminal, Since the mobile terminal does not have the location information of the mobile terminal itself and the location information of the base station, the mobile terminal cannot grasp the positional relationship with each base station. There was a problem that it was not possible to grasp whether it was possible to connect with a good base station.

  In addition, the mobile terminal cannot receive the broadcast information by the broadcast channel during communication on the dedicated channel allocated from the base station, or even if it can receive the broadcast channel, the transmission capacity of the broadcast channel is small. However, there is a problem in that the channel usage status of the base station cannot be grasped during communication, and when the user moves between the base stations, there is a possibility that the throughput may be reduced or the communication may be interrupted.

  Furthermore, a user who uses a mobile terminal can call the mobile communication carrier by telephone to know the failure information of the radio base station and base station control device of the mobile communication system, the scheduled operation stop due to maintenance, and the like. There has been a problem that it is necessary to inquire or to browse maintenance information provided on the Internet by the mobile carrier.

  The present invention has been made in order to solve the above-described problems, and reliably distributes various traffic information based on the position of each mobile terminal as well as the channel usage status of the radio base station. An object is to provide a traffic information providing system that can be used.

  According to the present invention, the traffic information providing system uses the traffic information server to determine the communication area where the mobile terminal is located and the surrounding communication areas based on the position information from the mobile terminal provided with the position information acquisition unit. By distributing the traffic information of the radio base station and the base station control device in various ways, the user of the mobile terminal can surely grasp the traffic situation of the communication area where the mobile terminal exists and the surrounding area.

  In addition, it is possible to move to the surrounding area so as to ensure the quality and throughput necessary for continuous use of the application being communicated by the mobile terminal, and improve the convenience for the user and the frequency by using the free channel Can be used effectively.
