    • Routing calls using a new protocol message which is a redirect message in a telecommunication system having a number of switching nodes to avoid circular paths among the switching nodes and for rerouting calls in the event of failures or overload conditions. During the establishment of a call from an originating switching node to a destination switching node where the call path has already been setup from the originating switching node through an intermediate switching node, a switching node is responsive to a setup message from the intermediate switching node requesting extension of the call path through the switching node to determine if such an extension would create a circular path. If circular path would be created, the switching node redirects the call (by using the redirect message) back to the intermediate switching node and indicates in that message to which switching node the call path should be extended. In response to the redirect message, the intermediate switching node reroutes the call path. Further, the redirect message entirely removes the call path between the switching node and intermediate switching node.
    • 在具有多个交换节点的电信系统中使用新的协议消息来路由呼叫,该协议消息是一个重定向消息,以避免交换节点之间的循环路径以及在发生故障或过载条件的情况下重新路由呼叫。 在从起始交换节点到目的地交换节点的建立呼叫路径已经通过中间交换节点从起始交换节点建立呼叫路径的呼叫期间,交换节点响应于来自中间交换节点的建立消息,请求 通过交换节点扩展呼叫路径,以确定这样的扩展是否会创建一个循环路径。 如果创建循环路径,则交换节点将呼叫(通过使用重定向消息)重定向回中间交换节点,并在该消息中指示该消息,呼叫路径应该被扩展到哪个交换节点。 响应于重定向消息,中间交换节点重新路由呼叫路径。 此外,重定向消息完全去除了交换节点和中间交换节点之间的呼叫路径。
