Abstract:
A communications network, comprising:a circuit-switched communications subnetwork; a packet-switched communications subnetwork; an Internet Protocol-based communications subnetwork, connected to send and receive data between the circuit-switched subnetwork and the packet-switched subnetwork, said Internet Protocol-based communications subnetwork comprising: a call agent receiving signaling data from the circuit-switched communications subnetwork for outgoing calls and receiving signaling packets from packet-switched communications subnetwork for incoming calls; a media gateway receiving bearer data from the circuit-switched communications subnetwork for outgoing calls and receiving non-data related packets from the packet-switched communications subnetwork for incoming calls; a servicing generalized packet radio service support node receiving packets for incoming calls to the circuit-switched communications subnetwork from a public data network through a gateway generalized packet radio service support node utilizing a generalized packet radio service tunneling protocol, wherein the servicing generalized packet radio service support node routes non-data related packets to the media gateway and routes signaling packets to the call agent; wherein a communications path between the circuit-switched communications subnetwork and the packet-switched communications subnetwork is established through the Internet Protocol-based communications subnetwork.
