Abstract
A media gateway (MGW), and methods related thereto, for controlling the routing of data packets through a “connectionless” packet-switched network, without bearer-channel control signaling. In an exemplary embodiment, an Integrated Services Digital Network User Part (ISUP) Initial Address Message (IAM) is transmitted from a controller -A associated with a MGW -A to a controller -B associated with a MGW -B; the IAM includes a source address for data packets at the MGW -A. The controller -B sends a resource allocation message to the MGW -B, which defines and stores an association between the source address for the data packets and an address associated with the MGW -B in a mapping table Subsequently, when the MGW -B receives a broadcast message including an unknown destination indicator, it queries the mapping table using the source address of the broadcast message. If the source address of the broadcast message is found in the mapping table the MGW -B retrieves the address of the MGW -B that is mapped to the source address and routes the broadcast message to that address.
