  • Patent number: 9118598
    Abstract: A redirector, a relay, a system for configuring route information, and a method for updating route information are disclosed herein. The redirector includes: a route storing module and a route indicating module. The redirector further includes: a monitoring module which is coupled to communicate with the route storing module and configured to monitor change of the route configuration information; and a notifying module which is coupled to communicate with the monitoring module and configured to send a notification to the intermediate node managed by the redirector, where the notification indicates that the route information corresponding to the changed route configuration information is invalid. Through the foregoing solution, after the route configuration information changes, a notification may be sent in time to indicate that the previously subscribed route indication information is invalid, thus better ensuring correct forwarding of the service request message and improving the QoS.

  • Patent number: 7894353
    Abstract: A method, system, and apparatus for diagnosing a route in a network based on a Diameter protocol are provided. The method includes the following steps. A source Diameter node generates a diagnosis message and sends it. An intermediate Diameter node adds diagnosis information thereof to the diagnosis message after receiving it and forwards it until the diagnosis message is forwarded to a Diameter server capable of processing the diagnosis message or a Diameter node incapable of forwarding the diagnosis message. The Diameter server or the Diameter node generates a response message and sends it carrying diagnosis information thereof, information in the diagnosis message, and a response type. The intermediate Diameter node adds the diagnosis information thereof to the response message after receiving it, and forwards it until the response message is forwarded to the source Diameter node. The source Diameter node parses the response message to obtain route related information.
