Abstract
The present invention provides a method for conveying information over a communication network such as a Digital Loop Carrier network free of in-band signaling information for at least a portion of an established communication between at least two users so as to reduce the information error rate associated with the established communication.
Claims26
A method for conveying information in a communication network that follows a protocol that supports in-band signaling, the method comprising the steps of:
- (a) establishing communications over a link of the communication network during a call between at least two users in accordance with the protocol, wherein the communications between the at least two users comprise an exchange of signaling information over the link using in-band signaling in addition to an exchange of user information over the link;
- and
- (b) after establishing the communications, but during the call, suspending in-band signaling such that communications over the link continue in a clear channel mode free of in-band signaling.
A first node for conveying information in a communication network that follows a protocol that supports in-band signaling, the first node comprising:
- (a) a port configured to support communications over a first link to a second node of the communication network;
- and
- (b) one or more ports configured to support communications over one or more other links to one or more other nodes of the communication network, wherein:
- the first node is configured to establish communications over the first link with the second node during a call between at least two users in accordance with the protocol, wherein the communications between the first and second nodes comprise an exchange of signaling information over the first link using in-band signaling in addition to an exchange of user information over the first link;
- and
- the first node is configured to suspend in-band signaling after establishing the communications, but during the call, such that communications over the first link continue in a clear channel mode free of in-band signaling.
A method for conveying information in a communication network that uses in-band signaling, the method comprising the steps of:
- (a) establishing communications with in-band signaling over a link between at least two users of the communication network;
- and
- (b) suspending in-band signaling during communications over the link between the at least two users allowing the information to be conveyed in a clear channel mode over the link.
A method for conveying information in a communication network that uses in-band signaling, the method comprising the steps of:
- (a) establishing communications between at least two users of the communication network;
- (b) suspending in-band signaling during communications between the at least two users allowing the information to be conveyed in a clear channel mode;
- and
- (c) returning to in-band signaling for communications between the at least two users.
