Gb over IP的技术研究与系统设计

Technique Research and System Design on Gb over IP

随着数据业务的快速发展,中国移动GPRS核心网Gb链路占用率迅速提高,Gb over FR已不能满足新的要求,在IP网上承载Gb流量已经成为提高网络服务质量及竞争力的重要手段。对Gb接口的连接及Gb over IP的优势进行分析并综合考虑SNSN与BSC的分布情况提出3种组网方案。最后以A省为例提出SGSN/BSC设备改造、Gb接口IP配置、站点接入、带宽计算以及总体组网设计方案。

With the rapid development of GPRS, the occupation ratio of Gb link in China mobile GPRS core network has been increasing quickly. Gb over FR now can＇t meet the new demands. Gb over IP has became an important way to raise the network QoS and to improve the competitive power. The technology of Gb over IP on Gb interface connection and its advantages are analyzed in this paper. The three kinds of network organization plans via an overall consideration on the distribution of SGSN and BSC are proposed. Finally, based on the example of A province, a plan including the equipment modification of SGSN and BSC, IP configure of GB interface, workstation access, bandwidth computatiofi and a overall solution on network design is put forward.
