Call hold with reminder and information push
View Patent ↗A broadband communication system including an Internet Protocol Telephony Network and public switched telephone network, including apparatus and methods for placing a call on hold in a way that significantly reduces the amount of network bandwidth utilized by the call while the call is on hold. When a call is placed on hold, embodiments of the architecture of the telephony network of the present invention allows the network to essentially “forget” about the call placed on hold. In other words, a call that is on hold may require very little, or even zero, bandwidth within the telephony network. Accordingly, the total necessary bandwidth capacity of the telephony network may be smaller than it would be if calls on hold were to consume precious network bandwidth as is found in existing telephony systems.
1. In an internet protocol (IP) telephony network, a method for pushing information while a call over an IP telephony connection between a first party and a second party is on hold, the method comprising
the network receiving from the first party a first request to place the call on hold;
responsive to the first request to place the call on hold, the network forwarding to the second party a second request to place the call on hold;
the network receiving from the first party a call hold information request while the call is on hold; and
responsive to the call hold information request, the network generating a stream of IP packets and forwarding to the second party while the call is on hold the stream of IP packets representing at least one of audio, video, speech, text, data, graphics, and multimedia,
the network maintaining said call as an ongoing call over said IP telephony connection without said connection being disconnected, and without said connection being terminated, and without said connection being torn down during the entire period that said first and second parties are on hold.
2. The method of claim 1 wherein the call is a real-time call.
3. The method of claim 1 wherein the stream of IP packets forwarded to the second party represents at least one of audio, video, speech, text, data, graphics, and multimedia depending upon a content of the call hold information request.
