1. A telecommunications system, comprising:
- a plurality of network clients including a positioning controller and a communications controller; and
a positioning server configured to receive coordinates from said positioning controller;
wherein said positioning server includes a periodic timer,wherein said positioning server is configured to send, upon periodic expirations of the periodic timer, a timer tick signal to associated ones of said network clients,wherein said associated ones are configured to send, responsive to said timer tick signal, a response tick signal to the positioning server,wherein said associated ones are further configured to send, after the response tick signal is sent, the coordinates to the positioning server responsive to detecting a change in a current position of said associated ones.

7. A telecommunications device, comprising:
-
a positioning controller adapted to determine coordinates for said telecommunications device; and a wireless data controller adapted to receive said coordinates from said positioning controller and a timer tick signal from an associated server upon periodic expiration of a periodic watchdog timer that begins a first count upon activation with the associated server, wherein said wireless data controller is further adapted to send, responsive to receipt of the timer tick signal, a response tick signal to the associated server, wherein said wireless data controller is further adapted to cause, after the responsive tick signal is sent, said coordinates to be transmitted to the associated server responsive to detecting a change in a current position. - View Dependent Claims (8, 9)

10. A telecommunications server, comprising:
-
a presence control unit adapted to receive and maintain presence information for a plurality of users; and a location control unit adapted to receive and maintain coordinates of said plurality of users, said coordinates being correlated with said presence information; wherein said location control unit includes a periodic timer being activated responsive to a registration of associated ones of a plurality of network clients with said telecommunications server, wherein said telecommunications server is adapted to send, upon periodic expirations of the periodic timer, a timer tick signal to said associated ones, wherein said associated ones are adapted to send. responsive to said timer tick signal, a response tick signal to the telecommunications server, wherein the telecommunications server receives, after the response tick signal is sent, said coordinates responsive to detecting a change in a current position of said associated ones. - View Dependent Claims (11, 12, 13)
