  • System and Method for Automatic Detection of UTRAN Topology
    Publication number: 20120113136
    Abstract: System and method for automatically detecting nodes, components and interfaces in a network. A preferred embodiment comprises detecting nodes in a network, wherein the nodes are coupled to a network controller, comprises identifying ports for the network controller, capturing messages received by the network controller at the ports, parsing the messages to identify a node address parameter, wherein the node address parameter uniquely identifies the node to the network controller, and if the node address parameter has not been previously identified, adding a new entry to a node database.
    Type: Application
