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.
