The SGSN connected to the destination RAN node decides which RAN node to send the message to based on the destination address or on the RIM routing address. 连接到目的RAN节点的SGSN将根据目的地址或RIM路由地址来决定给哪个RAN节点发送消息。
The main feature of this method is that the transmission of messages through a LN is independent of destination or origin addresses, namely, the routing of an intermediate node is independent from any address information. 该方法的主要特征是能使局部网络系统中的信件传递不依赖于信源与信宿的地址信息,即局部网络内,中间节点的路由选择与信件的地址信息无关。
