摘　　要：在WCDMA R5阶段,继承了R4的软交换架构思想,而且提出了Iu-flex技术,引入了池域的概念,一个池域就是由多个同类网元组成的共同控制一个或多个位置区的网元集合。核心网节点作为资源池,RNC可以连接多个MSC/SGSN网元、池域,打破了以往RNC与MSC间一对一的控制关系。RNC可被池中的多个网元管理,UE可以按照负载均衡的原则注册到池中的任意一个节点。R4 soft switch architecture was inherited in WCDMA R5. In addition,pool area was introduced in the Iu-flex technology. Pool area is the network element set,composed of a number of similar network elements. Elements in pool area are in control of one or more location area. When core network nodes act as a pool area,RNC can connect a number of MSC/SGSN network element,instead one to one control in R4. One RNC is managed by a number of network elements in the pool,so the UE connections could be distributed to any node in the pool with load balancing.
