In a cellular system, a new cell measures signal strengths of different channels being used, by existing cells. The new cell generates a list of candidate channels corresponding to the, channels with the greatest signal strength and transmits the list to the mobile switching center, (MSC) of the cellular system. The MSC determines which of the candidate channels correspond, to beacons in existing cells and transmits configuration information to the new cell for those, corresponding existing cells.

Why it's free to use
- Filed February 26, 1999 and granted July 2, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 26, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 26, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
