METHOD AND SYSTEM FOR A COMMUNICATIONS SESSION JOIN FUNCTION TO FACILITATE THE PROVISION OF ENHANCED COMMUNICATIONS SERVICES
First Claim
Patent Images
1. A method of joining communications sessions to establish a communications connection, comprising:
- receiving at a communications session join function in an Internet Protocol network first and second independent communications session requests sent on behalf of first and second endpoints;
applying application logic to determine a requirement to establish a connection between the first and second endpoints by analyzing information contained in the respective first and second communications session requests; and
sending from the communications session join function connected party information associated with the first endpoint toward the second endpoint and connected party information associated with the second endpoint toward the first endpoint to establish the communications connection.

Abstract
A method and system for joining independent but related communications sessions to form a communications connection uses a communications session join function to join independent communications sessions connected to first and second endpoints based on information contained in the respective independent first and second communications session requests. The communications session join function sends connected party information associated with the first endpoint towards the second endpoint and connected party information associated with the second endpoint towards the first endpoint to complete the communications connection.

5. The method as claimed in claim 5 further comprising receiving instructions from a converged services node that executes the application logic to join two SIP UAS transactions associated with the first and second communications session requests.
-
6. The method as claimed in claim 6 wherein sending the connected party information comprises sending a representative Session Description Protocol (SDP) of the first endpoint towards the second endpoint, and vice versa.
-
9. The method as claimed in claim 9 further comprising:
receiving the second communications session request at the communications session join function in response to sending the connect request.

11. A method of seamless handoff between cellular and wireless packet services on a dual mode mobile device, comprising:
-
determining by an application client operating on the dual mode wireless device that a first communications session carried by one of a cellular and a wireless packet communications services should be handed off to the other of the cellular and the wireless packet communications services, and sending from the dual mode wireless device a first communications session request to a call join function using the other of the cellular and the wireless packet communications services; and
automatically disconnecting from the one of the cellular and wireless packet communications services that carries the first call to prompt a service node embodying the call join function to send a connect request to the communications service that carries the first call so that a second communications session request is forwarded from that communications service to the call join function. - View Dependent Claims (12, 13, 14, 15)

16. A system for joining independent but related communications sessions to form a communications connection, comprising:
-
a communications session join function for joining the independent but related communications sessions connected to first and second endpoints on receiving first and second independent communications session requests sent to the communications session join function on behalf of the first and second endpoints, the communications session join joining the independent but related communications sessions by sending connected party information associated with the first endpoint toward the second endpoint and sending connected party information associated with the second endpoint toward the first endpoint; and
application logic for analyzing information contained in the respective first and second communications session requests received by the communications session join function to determine a requirement for joining the first and second independent communications sessions, and for instructing the communications session join function to join the independent but related communications sessions. - View Dependent Claims (17, 18, 19, 20)
