The reverse virtual call setup algorithm for mobility management in PCS networks
I Chih‐Lin, Gregory P. Pollini, Richard D. Gitlin · 2002
The increased demand for wireless mobile communications coupled with the finite available spectrum has motivated investigation into alternative methods of tracking users and delivering calls. We present a new scheme for delivering mobile terminated calls called reverse virtual call setup (RVC) and discuss its performance using the metrics of fixed network cost, and call setup delay. New MAP messages needed to implement the RVC protocol are specified . We identify the conditions under which the fixed network signaling system loading and call setup delay are reduced. In particular we show that the performance improvement over the conventional strategy depends upon the degree of resolution that the system must track a user's location.
