  • Method and apparatus for redundant signaling links
    Patent number: 9332037
    Abstract: According to at least one embodiment of the invention, a protocol for managing redundant signaling links to form a reliable signaling connection is provided. The protocol has an initialization phase, in which the availability of signaling links is determined and an available signaling link is selected and activated, followed by an operational phase in which the activated link is used for sending signaling messages for a higher-level protocol. During the operational phase both links are monitored for availability using a query and reply technique. Should either link fail, a status message is sent to the remaining available link along with an activity switchover being performed, as required, depending on whether the failed link was the active link.
    Type: Grant
