Abstract:
1. A method for diagnosing a feeder misconnection comprising: determining, within different predetermined angle ranges, a number of terminals using a sector to be analyzed as a serving cell; determining a direction of a sector with a maximum number of terminals using the sector to be analyzed as the serving cell as an actual distribution direction of users of the sector to be analyzed; determining, according to whether the actual distribution direction of users of the sector to be analyzed is consistent with a planned direction of users of the sector to be analyzed, whether a feeder of the sector to be analyzed is misconnected, and wherein the method further comprises at least one of the following steps: determining that a sector crossed feeder exists between the sector to be analyzed and a second sector of a base station when the actual distribution direction of users of the sector to be analyzed is contrary to an actual distribution direction of users of the second sector of the base station where the sector to be analyzed is located, and differences of user signals received by mains and diversities of both the sector to be analyzed and the second sector do not exceed a predetermined difference threshold; determining that a main of the sector to be analyzed and a main of the second sector are inversely connected, and a diversity of the sector to be analyzed and a diversity of the second sector are normal when the actual distribution direction of users of the sector to be analyzed is contrary to the actual distribution direction of users of the second sector, and the differences of user signals received by the mains and the diversities of both the sector to be analyzed and the second sector exceed the predetermined difference threshold; determining that the main of the sector to be analyzed and the diversity of the second sector are inversely connected, and the diversity of the sector to be analyzed and the main of the second sector are normal when the actual distribution directions of users of both the sector to be analyzed and the second sector are a planned distribution direction of users of the sector to be analyzed, and the differences of user signals received by the mains and the diversities of both the sector to be analyzed and the second sector exceed the predetermined difference threshold; and determining that the diversity of the sector to be analyzed and the diversity of the second sector are inversely connected, and the main of the sector to be analyzed and the main of the second sector are normal when the mains of the sector to be analyzed and the second sector are not misconnected, but the differences of user signals received by the mains and the diversities of both the sector to be analyzed and the second sector exceed the predetermined difference threshold.
