Method for determining neighboring base station, base station, and processing network element
The present invention provides a method for determining a neighboring base station, a base station, and a processing network element. The method for determining a neighboring base station includes: receiving, by a base station, a measurement report, sent by a terminal, of another base station adjacent to the base station; sending, by the base station, the measurement report to a processing network element; and determining, by the processing network element, a neighboring base station of the base station according to the measurement report. The technical solution provided in the present invention can be used to determine a neighboring base station of a base station, which avoids a problem in the prior art that an error is likely to occur in manually determining a neighboring base station of a base station, thereby improving accuracy of determining a neighbor relationship between base stations.
1. A method for determining a neighboring base station, the method comprising:
receiving, by a processing network element, a path loss, sent by a first base station, of a signal, wherein the path loss of the signal is a path loss obtained by the first base station according to the signal that is transmitted by a second base station and received by the first station; and
determining, by the processing network element, a neighboring base station of the first base station according to the path loss of the signal; and
wherein after determining, by the processing network element, a neighboring base station of the first base station according to the path loss of the signal, the method further comprises:
allocating, by the processing network element, scrambling codes to the first base station and the neighboring base station of the first base station according to the determined neighboring base station of the first base station, wherein a scrambling code of each base station is different;
wherein allocating, by the processing network element, scrambling codes to the first base station and the neighboring base station of the first base station according to the determined neighboring base station of the first base station, wherein a scrambling code of each base station is different, comprises:
determining, by the processing network element according to the determined neighboring base station of the first base station, that the neighboring base station of the first base station is a base station whose scrambling code is mutually exclusive from that of the first base station; and
selecting, by the processing network element, a scrambling code from scrambling code resources, allocating the selected scrambling code to the first base station, determining whether the scrambling code is the same as a scrambling code of the base station whose scrambling code is mutually exclusive from that of the first base station, and if the two scrambling codes are the same, and selecting, by the processing network element, another scrambling code from the scrambling code resources until the scrambling code allocated to the first base station is different from the scrambling code of the base station whose scrambling code is mutually exclusive from that of the first base station.
2. The method for determining a neighboring base station according to claim 1 , wherein determining, by the processing network element, a neighboring base station of the first base station according to the path loss of the signal comprises:
when the path loss of the signal is less than or equal to a preset path loss threshold, determining, by the processing network element, that the second base station which transmits the signal is the neighboring base station of the first base station.
3. The method for determining a neighboring base station according to claim 2 , wherein after determining, by the processing network element, a neighboring base station of the first base station according to the path loss of the signal, the method further comprises:
configuring, by the processing network element, the determined neighboring base station of the first base station as a neighboring cell of the first base station.
