Call context conveyance
First Claim
Patent Images
1. A method of exchanging context information, the method comprising:
- obtaining transitive context information, by a telecommunications server of a communication system, for a first call involving a first user and a second user, but not a third user;
configuring, by the telecommunications server, a Session Initiation Protocol (SIP) message to be transmitted in connection with establishment of the first call;
including, by the telecommunications server, the transitive context information in the SIP message configured, by the telecommunications server, to be transmitted in connection with establishing a second call between the third user and at least one of the first user and the second user;
wherein the transitive context information is associated with one of two categories of transitive context information;
1) consume or
2) relegate; and
wherein the transitive context information includes a data element that conveys notes about the call, wherein the at least some of the notes are created by at least one of the first and second users involved in the first call, and wherein the at least some of the notes are used in the second call that occurs after the first call in which the data element is included is completed.

Abstract
A communication system, method, and components are described. Specifically, a communication system having the ability to carry a transitive context and communicate the transitive context to new participant user agents for continuity through all related call dialogs is disclosed. The transitive context communication is possible through the use of a newly created SIP dialog using a REFER message and/or an INVITE message for all call flows and topology change operations.

1. A method of exchanging context information, the method comprising:
-
obtaining transitive context information, by a telecommunications server of a communication system, for a first call involving a first user and a second user, but not a third user; configuring, by the telecommunications server, a Session Initiation Protocol (SIP) message to be transmitted in connection with establishment of the first call; including, by the telecommunications server, the transitive context information in the SIP message configured, by the telecommunications server, to be transmitted in connection with establishing a second call between the third user and at least one of the first user and the second user; wherein the transitive context information is associated with one of two categories of transitive context information;
1) consume or
2) relegate; andwherein the transitive context information includes a data element that conveys notes about the call, wherein the at least some of the notes are created by at least one of the first and second users involved in the first call, and wherein the at least some of the notes are used in the second call that occurs after the first call in which the data element is included is completed. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A system comprising a telecommunications server and the telecommunications server further comprises:
-
means to obtain transitive context information for a first call involving a first user and a second user, but not a third user; means to configure a Session Initiation Protocol (SIP) message to be transmitted in connection with establishment of the first call; means to include the transitive context information in the SIP message configured to be transmitted in connection with establishing a second call between the third user and at least one of the first user and the second user; wherein the transitive context information is associated with one of two categories of transitive context information;
(1) consume or (2) relegate; andwherein the transitive context information includes a data element that conveys notes about the call, wherein at least some of the notes are created by at least one of the first and second users involved in the first call, and wherein the at least some of the notes are used in second call that occurs after the first call in which the data element is included is completed. - View Dependent Claims (10, 11, 12, 13)

14. A communication system, comprising:
-
a transfer hardware configured to obtain transitive context information obtained for a first call involving a first user and a second user, but not a third user and performs the following operations; configure a Session Initiation Protocol (SIP) message to be transmitted in connection with establishment of a second call between the third user and at least one of the first user and the second user; wherein the transitive context information from the first call is included in the SIP message; and wherein the transitive context information from the first call is identified as belonging to one of two categories of transitive context information;
(1) consume and (2) relegate; andwherein the transitive context information includes a data element that conveys notes about the first call, wherein the notes are created by at least one of the first and second users involved in the first call, and wherein the notes are used in the second call that occurs after the first call in which the data element is included is completed. - View Dependent Claims (15, 16, 17, 18, 19, 20)
