Abstract
The present invention monitors call signaling events stemming from a circuit-switched call between a caller and a called party and controls a packet-session between user agents on respective endpoints associated with the caller and called party. The endpoints may include any type of computational device capable of facilitating the packet-session over a packet-switched network. Control of the user agents may be provided via a proxy for the user agents and may use the session initiation protocol (SIP), or like session control protocol for communications.
Claims34
A method for integrating separate circuit-switched voice and packet-switched data sessions, comprising:
- a. receiving notification of at least one call signaling event for a separate circuit-switched call between a caller and a called party over a circuit-switched network;
- and
- b. controlling a separate packet-switched session for a packet-session between a caller user agent for a caller endpoint and a called party user agent on a called party endpoint based on at least one of the call signaling events for the separate circuit-switched call, wherein the caller and called party are associated with the caller and called party endpoints, such that the caller and called party may conduct concurrent voice and data sessions.
A SIP integration server, comprising:
- at least one processor;
- at least one memory device storing instructions executable by the at least one processor to:
- a. receive notification of at least one call signaling event for a separate circuit-switched call between a caller and a called party over a circuit-switched network;
- and
- b. control a separate packet-switched session for a packet-session between a caller user agent for a caller endpoint and a called party user agent on a called party endpoint based on at least one of the call signaling events for the separate circuit-switched call, wherein the caller and called party are associated with the caller and called party endpoints, such that the caller and called party may conduct concurrent voice and data sessions.
A system for integrating separate circuit-switched voice and packet-switched data sessions, comprising:
- a signaling control point operable to transmit a trigger when a calling user connected to a called user by a circuit-switched call handled by the signaling control point indicates interest in establishing a packet-switched data session with the called user;
- and
- a SIP integration server operable, in response to the trigger, to exchange messages with user agents of the calling user and the called user to establish the packet-switched data session.
A method for integrating separate circuit-switched voice and packet-switched data sessions, the method comprising:
- operating a signaling control point to transmit a trigger when as calling user connected to a called user by a circuit-switched call handled by the signaling control point indicates interest in establishing a packet-switched data session with the called user;
- and
- operating a SIP integration server, in response to the trigger, to exchange messages with user agents of the calling user and the called user to establish the packet-switched data session.
