For non-access stratum signaling or traffic, dynamic routing node could select a relatively free switching element via an additional relay link for transferring and switching when the default core switching element or link is overloaded.

对于非接入层信令或者业务，当缺省的核心交换单元或者传输链路过负荷时，动态路由节点可以通过附加的中继链路选择一个相对空闲的交换单元实现传输和交换。

Each RNC ( radio network controller) could be connected to multiple core switching elements through introducing one dynamic routing node between core switching node and RNC.

通过在核心网交换节点和无线网络控制器（Radio Network Controller，RNC）之间引入一个动态路由节点，使得每个RNC可以连接到多个核心交换单元。
