A back haul architecture effectively reduces the reactivation times for both forward-link, and reverse-link data transmissions over CDMA wireless communications systems by relying on, packet-mode transmissions over the back haul between a frame selection/distribution (FSD), function and the appropriate base stations for both forward-link data and reverse-link data. In, particular, for the forward direction the FSD function transmits forward-link data only to one base, station (i.e. the primary base station) which is solely responsible for , controlling the forward-link air interface with the corresponding mobile unit.

Why it's free to use
- Filed June 9, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 9, 2020.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
