摘要
介绍了SGSN Pool主要技术和2种组网方式;相比传统的分组域核心网,SGSN Pool组网模式打破了一个BSC/RNC只能连接到一个SGSN的限制。详细描述了终端在SGSN Pool中的移动性管理;SGSNPool的拆卸功能:负荷重分配机制;以诺西的产品为例,提出了在现有的网络中实施SGSN Pool的一些建议,包括NRI长度和NSEI数量的规划以及核心网侧的相关要求。
SGSN Pool technology is new introduced in 3GPP TS 23.236 Release 5. With this, one BSC/RNC could be connected to more than one SGSN by introducing the pool area system. This article describes the SGSN Pool technical principle, the mobility management for terminals in Pool areas, the removing of SGSN from SGSN Pool. Finally, some suggestions are proposed for SGSN Pool configuration in real network based on NSN products.
