45results about How to "Improve activity efficiency" patented technology

An improved mechanism for sharing information between a non-voice session and a voice session is described. Clients use communication devices to exchange voice information over voice sessions to voice node servers and exchange non-voice information over non-voice sessions to WAP gateways. Information about the activity in a session is stored as context data. When a client switches from communication over one type of session to another, context data for that client is located and retrieved. The retrieved context data is used to recreate the state of the prior session, thus eliminating the need to reenter information that was previously available.
