  • System and method for automatic discovery of topology in an LTE/SAE network
    Patent number: 8972588
    Abstract: A system, method and computer program product are disclosed for monitoring a telecommunications network that comprises a plurality of Mobility Management Entity (MME) nodes and a plurality of evolved UTRAN NodeB (eNodeB) nodes coupled by S1-MME interfaces. A Stream Control Transmission Protocol (SCTP) association identifier is assigned to an SCTP association between interconnected MME and eNodeB nodes. Specific S1-MME messages allow discovering the MME nodes and the eNodeB nodes with their network identifiers, identifying the connections between them and populating proper tables for this topology information.
    Type: Grant
