Abstract
A call processing system includes an access gateway that has a local switching unit. The access gateway, in operation, provides access to voice signals and data signals. The call processing system also includes a call feature server that has a host interface platform configured to connect to the access gateway through a network. The call feature server, in operation, provides call control functionality to the local switching unit. The call feature server is configured to provide bearer control signals through a packet network to establish a bearer channel.
Claims49
A call processing system, comprising:
- an access gateway including a local switching unit, the access gateway, in operation, providing access to voice signals and data signals;
- and
- a call feature server having a host interface platform configured to connect to the access gateway through a network, the call feature server, in operation, providing call control functionality to the local switching unit, the call feature server configured to provide bearer control signals through a packet network to establish a bearer channel.
A method of call processing, comprising:
- connecting a network to a call feature server having a host interface platform;
- connecting the network to an access gateway having a local switching unit;
- receiving a request to route a call from the access gateway;
- sending a control signal from the call feature server to the local switching unit to route the call;
- and
- sending a bearer channel control signal to establish a bearer channel.
A call feature server for a call processing system comprising:
- a centralized controller to send control signals to a plurality of distributed processors,
- a local area network (LAN) to couple the centralized controller to each of the plurality of distributed processors to perform decentralized call processing;
- and
- a host interface platform connecting the LAN to a network to send control signals and bearer signals, the host interface platform configured to interface with a packet network.
A method of call processing, comprising:
- receiving a request to route a call;
- and
- sending control signals via a host interface platform through a network to set-up the call;
- and
- sending bearer control signals.
An access gateway for a call processing system, comprising:
- a local switching unit to set-up a call;
- a media gateway capable of TDM signal and packet message conversion, the media gateway receiving control signals from a network, the media gateway providing bearer control signals to the local switching unit from a call feature server;
- and
- a multiplexer to perform circuit emulation of TDM signals from the network.
A method of call processing, comprising:
- receiving a request to route a call;
- converting time division multiplex (TDM) signals to a packet compatible format;
- sending the request via a packet network to a call feature server;
- and
- receiving control signals via the packet network from the call feature server to route the call.
A call processing architecture, comprising:
- a first platform including a call feature server, the call feature server configured to provide bearer control through a packet network;
- and
- a second platform including an access gateway connected to the call feature server via the network, the access gate way including a media gateway providing TDM and packet based conversion;
- wherein the first platform and the second platform each are configured to support an IP network, an ATM network and a TDM network.
