Open the CIPO recordAbstract From the Canadian patent
A method and system for ensuring that handoff requests take priority over new cell requests to engage voice channels assigned to a particular target cell are provided. A certain number of channels are reserved for handoff requests. However, if no channels reserved or, unreserved, are available handoff requests to a, particular target cell are stored in a corresponding queue for a predetermined period of time. Thus when, voice channels become available, they are seized in order to satisfy the handoff requests stored in that queue. If the handoff queue is empty, new call requests to a target cell may be assigned to available voice channels.

Why it's free to use
- Filed December 8, 1992 and granted August 20, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 8, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 8, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
