Abstract
Abstract The SS7 interface of a conventional GPRS-136 or GPRS-136HS network is replaced with an IP interface. An IP interface is placed between the ANSI TIA/EIA-41 circuit-switched network and the GPRS-136 packet-switched network. This interface can handle both signaling and bearer traffic and thereby overcomes the limitations imposed by the current SS7 interface, which can handle only signaling.
