A method is provided for the automatic discovery and updating of gateway peers within a WiMAX Access Service Network in order to control R4 intra-ASN mobility. In a preferred embodiment, When a WiMAX Access Service Network Gateway is added to the network, it propagates an AUTO-DISCOVER message using the Open Shortest Path First protocol's opaque Link State Advertisement. The received messages are used to establish connections to the sending peer based on data packaged in the Link State Advertisement. Once a connection has been established, UPDATE and CONFIRM messages are used by Access Service Network Gateways to exchange WiMAX R4 routing information. The message sequence number is used to correspond UPDATE and CONFIRM messages. The OSPF-based keep-alive mechanism is used to determine whether internal peers are reachable.
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:
A computer program product for updating peer Access Service Network Gateways (ASGs) in a WiMAX network with WiMAX R4 information, the computer program product comprising a non-transitory computer-readable medium having stored thereon computer-executable instructions that, if executed by a computing device, cause the computing device to perform operations including:
