Abstract
A solution of reconstructing the network topology according to the traffic related information of each cell is proposed in the present invention, so as to achieve self-optimization of network. The traffic related information of a cell includes the traffic related information applicable to network topology reconstruction, or load related information as is named, including but not limited to time-frequency resource related amount that is used by the traffic data in the cell, traffic throughout of each cell or the wireless channel quality of each cell for transmitting traffic data, etc. The solutions in the present invention realize the network topology reconstruction according to traffic related information of multiple cells, therefore the network capacity and service quality could be effectively improved and the wireless relay communication network is applicable to those areas with unpredictable traffic distribution. And the network topology reconstruction function in the present invention can simplify network planning and network management, so that network deployment cost and maintenance and management expenses could be saved.
