  • Method and apparatus for diagnosing feeder misconnection
    Patent number: 8594658
    Abstract: The present invention relates to a method and an apparatus for diagnosing a feeder misconnection. The method includes: for each planned non-co-site strong neighboring cell of a sector to be analyzed, by using each sector of a base station where the sector to be analyzed is located as an interference source, determining a sector having the greatest interference with the non-co-site strong neighboring cell; and when in the planned non-co-site strong neighboring cells of the sector to be analyzed, the sector having the greatest interference with the non-co-site strong neighboring cell is in another sector except the sector to be analyzed, and a ratio of the number of non-co-site strong neighboring cells of the another sector to the total number of the non-co-site strong neighboring cells reaches a preset first threshold, determining that a feeder of the sector to be analyzed is misconnected.
