Patent ID: 7697936

Claim:
A base station apparatus, comprising: radio communication parameter notification means for notifying a pair of an identifier for identifying the base station apparatus and a radio communication parameter for identifying the base station apparatus to another base station in the neighborhood of the base station apparatus; information acquisition means for acquiring information about at least one of a path loss value, a reception level and an arrival time difference over a control channel, and also acquiring another pair of another identifier for identifying said another base station apparatus and another radio communication parameter for identifying said another base station apparatus, the path loss value being a difference between a transmission power of said another base station apparatus and a reception power of a mobile station; and radio communication report parameter update means for setting and updating the pair of the identifier and the radio communication parameter to be reported by the base station apparatus, based on the information acquired by said information acquisition means; wherein said radio communication report parameter update means sets a pair, having a smaller preset path lost value, out of the pairs of the identifiers and the radio communications parameters, as a preferentially reported pair, and if the path loss values of the pairs are equal, said radio communication report parameter update means sets a pair having a greater number of appearances as the preferentially reported pair.
