- 中文摘要: 本論文旨在探討細胞式個人通信系統中應用於手機進接之無線通道指定演算法之性能,本文提出了數種通道進接程序,並用BONeS模擬工具建構-36基地台之模擬系統,進行模擬。根據模擬結果顯示,在10%服務等級(Grade ofService)的條件下:具負載共享(Load Sharing)機制之系統容量比直接重試(Directed Retry)系統多出約0.9歐蘭(Erlangs),且優於準固定通道指定(Quasi-Fixed Channel Assignment)系統約2歐蘭。
- 英文摘要: This paper reports the performance of radio assignment algorithms for portable access in cellularsystems. Several channel access procedures are proposed and simulated using BONeS simulation of a36-port system model. Simulation results show that the load sharing system is better than the directedretry system by around 0.9 Erlangs while it is better than the QFCA (Quasi-Fixed Channel Assignment)system by around 2 Erlangs if the GOS (Grade Of Service) is constrained to less than 10 percent.
