Architecture and Methodology for Mobile-Executed Handoff in Cellular ATM Networks

Anthony Acampora and Mahmoud Naghshineh

One-line summary: A virtual connection tree, overlaid on the graph of connected ATM switches ("basestations"), allows low-latency handoff without involving the Network Call Controller in every handoff and requires minimal extra hardware at the root node of the tree. Two QoS metrics, basestation overloading probability and expected duration of overload, are computed using binomial-distribution basestation assignment as well as a dynamic model that models call connect/disconnect and handoffs.

Overview/Main Points


In the common case, handoff doesn't have to be complicated and can be based mostly on existing (fast) ATM switch routing algorithm.
