The fractional frequency reuse (FFR) method generally used to investigate the noise-limited cellular network in the system. In this paper, we drive the two different strategies, which are related to secrecy outage probability with the best base station (BS) serve and the nearest BS serve, by analysing the data of channel gains. For the noise, limited network in secrecy outage probability without FFR, two transmission schemes are analysed, i.e., nearest BS and best BS. Simulation results show that both the plans of transmitting with the best BS and the utilization of the FFR are gainful for physical layer security in the downlink cell systems.
