switching core

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。
