Abstract

A real-time communications system that is capable of convening an on-line meeting or teleconference involving text, audio, video, and/or data between multiple users of mobile and non-mobile devices. A mobile telephone is operative to receive an invitation to join an on-line meeting with at least one user of another mobile or non-mobile device. If the mobile telephone network can provide an indication of whether the mobile telephone is powered-on and within the coverage area of the mobile telephone network, a real-time messaging server employs this information to determine the on-line presence of the mobile telephone user before transmitting the meeting invitation. Otherwise, the real-time messaging server assumes that the mobile telephone user is present and on-line. The mobile telephone user may indicate his or her desire to join the on-line meeting by transmitting an SMS message to the real-time messaging server in response to the meeting invitation, after which the real-time messaging system may convene the on-line meeting between the multiple users.

Claims18

Dependent claims

A method of performing real-time communications between a plurality of clients, each client being communicably coupled to at least one communications network, at least one of said plurality of clients being a mobile device, said method comprising the steps of:

receiving a request for a real-time group action involving said plurality of clients,
wherein each of said plurality of clients has at least one condition associated therewith, a status of the condition associated with each client being indicative of an on-line presence of the respective client;
in a first determining step, in response to said request for said real-time group action, determining the on-line presence of each of said plurality of clients;
in a second determining step, in the event the on-line presence of said mobile device is indeterminate, determining whether said mobile device is configured to receive at least one message over said at least one communications network;
in the event said mobile device is configured to receive said at least one message over said at least one communications network, assuming that said mobile device is present and on-line;
in a third determining step, determining whether said real-time group action can be performed based at least in part on the on-line presence of each of said plurality of clients;
and
in the event said real-time group action can be performed based at least in part on the on-line presence of the respective clients, performing said real-time group action.
