Abstract

The invention provides a method and a system for determining positions of newly-added relay stations. The method comprises the following steps: presetting at least two positions as positions of the newly-added relay stations in a cell, wherein at least one existing relay station is arranged in the cell; calculating probabilities that eavesdroppers appear at the positions in the cell through a preset function; calculating influence values of the newly-added relay stations corresponding to the positions influencing the out-degrees of the existing relay stations or calculating the out-degrees of the existing relay stations after the existing relay stations are influenced by the newly-added relay stations corresponding to the positions; calculating a total influence value of the influences of the newly-added relay stations corresponding to the positions on the out-degree of a whole cell network; or calculating the total out-degree of the whole cell network after the whole cell network is influenced by the newly-added relation stations corresponding to the positions; and selecting at least one position according to the total influence value or the total out-degree to serve as the positions of the newly-added relay stations. Through adoption of the method and the system for determining the positions of the newly-added relay stations, the connectivity of the cell network can be enhanced, and the eavesdropping probability of information transmitted in the cell network is kept at a relatively low level.

Description

technical field [0001] The invention belongs to the technical field of mobile networks, and in particular relates to a method and system for determining the position of a newly added relay station. Background technique [0002] Under the combined effect of new technologies and market demands, the trend of future network development must be to make greater technological innovation and breakthroughs in network access systems. Considering that the trend of the future access network is globalization, integration and personalization, it is necessary to find ways to increase the speed and coverage of the access network. In order to solve these problems, a better method is to add relay stations to assist the communication system to expand the service range and service quality of the base station. However, increasing the relay station also increases communication security risks. The introduction of the relay station makes the connection relationship between different facilities in...
