US Patent Issued to TeleCommunication Systems on Feb. 22 for "Mobile Activity Status Tracker" (Maryland Inventors)

ALEXANDRIA, Va., Feb. 25 -- United States Patent no. 7,894,825, issued on Feb. 22, was assigned to TeleCommunication Systems Inc. (Annapolis, Md.).

"Mobile Activity Status Tracker" was invented by Erik L. Wallace (Annapolis, Md.), Walter Weichselbaumer (Annapolis, Md.), Daniel J. Hronek (Annapolis, Md.), Mark Titus (Arnold, Md.) and Dara Ung (Odenton, Md.).

According to the abstract released by the U.

S. Patent & Trademark Office: "A technique and apparatus to provide status tracking of presence and/or location of a mobile, wireless device to a requesting entity even outside of a particular wireless system. This allows wireless service providers the ability to monitor and log changes in the status of mobile stations within and/or outside their networks. Embodiments are disclosed wherein presence and/or location information is provided to entities outside of a particular servicing wireless network using the mechanisms of call processing components of a mobile network (e.g., call setup procedures), and using standard mechanisms currently available to any appropriately conforming Mobile Switching Center (MSC) element. A mobile activity status tracker (MAST) is disclosed which contains a database of information similar to the information contained in the Home Location Register. The MAST tracks and reports status and activity of mobile wireless devices in a wireless network using mobile registration message, mobile inactivity message forwarding, and/or mobile automatic notification of subscriber status to TCP/IP entities (e.g., application servers on the Internet or Intranet). The MAST system duplicates the same or similar information contained in a corresponding HLR, but is available as an external database entity which is not restricted by SS7 standards. The tracking need not track call-specific information, e.g., called telephone numbers or information regarding conversations sustained by the tracked wireless subscribers."

The patent was filed on July 21, 2006, under Application No. 11/490,108.
