Open the CIPO recordAbstract From the Canadian patent
Radiocommunications systems having improved soft handoff capabilities are described. During soft handoff a mobile station may have several transmission sources (active set members) supplying it with substantially the same information. Mobile stations which are not moving may not require as many sources to provide adequate received signal quality. Therefore mobile , stations which are not moving are identified using locating techniques and members of the active set are compared with a higher threshold to remove weaker branches more rapidly than when using a threshold that is applied to mobile stations that are in motion.

Why it's free to use
- Filed April 27, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 27, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 27, 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.
