摘　　要：GSM900/DCS1800双频网具有许多共同点,组建双频网具备可能性。但GSM900与DCS1800也具有许多不同点,考虑的角度不同便有不同的组网方案。文中在分析建设双频网必要性及实现原理的基础上,依次给出了独立组网,共用MSC(不共用BSC),共用BSC,共用BTS,共用HLR/AUC、EIR、OMC和SMC五种不同的双频网组网方案,并给出了每种方案各自的特点、优点、缺点,最后通过对五种方案的比较分析给出了各自的适用场景。GSM900 and DCS1800 networks have many things in common,and thus it is possible to construct the double-frequency net.However,GSM 900 and DCS1800 also have some different points,and the different networking schemes are needed from different angles.Based on the necessity in construction of double-frequency net and its implementation principles,this paper proposes five different networking schemes,including independent networking,sharing MSC,sharing BSC,sharing BTS,and sharing HLR/AUC,EIR,OMC and SMC;gives their characteristics,advantages and disadvantages including their applicable scences.
