Using dynamic learning techniques by a system controller to determine a subset of neighboring cell sites to which an activity transfer should be attempted. An activity transfer can be a handoff or registration. The neighboring cell sites that should be chosen for an activity transfer are specified for each cell site. The specified neighboring cell sites are determined by the dynamic learning process. In a first embodiment, the dynamic learning is accomplished by accumulating statistical data that defines the average call duration of each of the selected neighboring sites after an activity transfer to each. Advantageously this average duration can include, the total call duration for two …

Why it's free to use
- Filed November 12, 1997 and granted February 5, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 12, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 12, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
