Abstract

Largely in response to the tremendous growth of allied presence services and applications to wireless users, an improved method and system for wireless subscriber presence determination is disclosed hereunder, which seeks to assuage the strain and impact on network resources which the existing art facilitate.

Claims

1. An improved system, fully integrated with existing wireless technologies and infrastructures for determining the presence of wireless and/or mobile devices, which alleviates the number of queries and encumbrances placed upon said networks as such.

2. The system of claim 1, wherein presence refers to that certain set of characteristics which define and/or identify the state of a wireless subscriber (including said subscriber'"'"'s connectivity or otherwise to network services at a given instance);

as for example whether s/he has turned on his/her mobile station(s) or s/he is on-line or off-line in connection with a particular service or activity.

3. The system of claim 1, which employs the functionality associated with the delivery of Short Message Services (SMS).

4. The system of claim 1, whereby the Presence Server receives a query from an external application for the purpose of determining if a given mobile subscriber is active.

5. The system of claim 4, whereby the Presence Server will in turn initiate a query in order to determine whether a mobile station is inactive or active.

6. The system of claim 5, whereupon for an inactive mobile station, the Presence Server emulates a SMS Center (SMS-C) for the purpose of establishing a notification trigger in the applicable network element (typically the Home Location Register (HLR) or Mobile Switching Center (MSC)).

7. The system of claim 6, whereupon reactivation of the mobile station, the core network infrastructure notifies the Presence Server of said reactivation using the procedures and operations associated with the delivery of SMS messages.
