1. A mobile communication apparatus, comprising:

  • a position detection circuit section configured for detecting a current position of the mobile communication apparatus;

    a map acquisition circuit section configured for acquiring a reception quality map expressing a relationship between reception positions at which information can be directly received from a fixed wireless station located at a fixed terrestrial position and direct reception quality index values respectively corresponding to the reception positions, each direct reception quality index value expressing a reception quality obtainable when information is directly received from the fixed wireless station at the corresponding reception position;

    a direct reception quality estimation circuit section configured for estimating a direct reception quality index value corresponding to the current position of the mobile communication apparatus, the estimation being based upon the acquired reception quality map and the detected current position of the mobile communication apparatus;

    a reception processing circuit section configured for selecting one of a first reception mode and a second reception mode, the first reception mode being an operating mode in which information is received directly from said fixed wireless station and the second reception mode being an operating mode in which a limitation is placed upon receiving the information directly from said fixed wireless station;

    a position acquisition circuit section configured for acquiring a current position of a candidate relay apparatus constituted by another mobile communication apparatus, anda relay quality estimation circuit section configured for estimating a relay reception quality index value expressing a reception quality obtained when information is relayed from the fixed wireless station via the candidate relay apparatus, the estimation being performed based upon the acquired current position of the candidate relay apparatus and the acquired reception quality map;

    wherein the reception processing circuit section;

    selects the first reception mode as the operation mode, when the direct reception quality index value exceeds a predetermined threshold value;

    when the direct reception quality index value does not exceed the predetermined threshold value, selects one of the first reception mode and the second reception mode as the operation mode, the selection being based upon comparing the relay reception quality index value with the direct reception quality index value; and

    when the second reception mode is selected, effects reception of information from the fixed wireless station via the candidate relay apparatus.
