摘 要: 分析了GPRS骨干网内移动终端之间相互通信的数据传输路由,针对其中存在的路由迂回问题,提出一种综合性能较优的路由优化方案。通过由SGSN分担部分数据处理使GGSN处理能力提高,通过GGSN的数据流量减少,缩短了数据迟延,同时SGSN的处理复杂度无显著增加。 We analyze the data routing between two mobile subscribers in the same GPRS PLMN. To solve the routing circularity inside this process, we put forward a synthetically better routing scheme. The SGSN shares GGSNs data process without remarkably raising its own complexity. GGSNs throughput capacity is improved and traffic flow is reduced. In addition, the optimized scheme cuts down data delay .
