Patent ID: 8428003

Claim:
A method for updating peer Access Service Network Gateways (ASGs) in a WiMAX network with WiMAX R4 information in response to an event related to a network element, the method comprising: an ASG generating a message containing WiMAX R4 routing and connectivity information that includes Type-Length-Value (TLV) information corresponding to the event, wherein the TLV information includes an ID and IP address of the network element; the ASG encapsulating the message in a first opaque Link-State Advertisement (LSA); and the ASG using an OSPF routing protocol, in addition to being used to update routers' link state databases with IP routing information, to propagate the first opaque LSA, wherein the first opaque LSA is usable upon receipt to extract the message from the first opaque LSA and extract the WiMAX R4 routing and connectivity information from the message.
