This is from somone who works in the industry as posted on SU: CDMA uses only one paging channel, but can do zone-based paging so the your phone isn't getting bombarded with pages. CDMA paging channel is usually set up to check for pages approximately every 5 seconds, this is what causes the delayed ring that people complain about in CDMA. I recently learned that CDMA vendors are going to be adding multiple paging channels in a future software release. That might then improve battery life, as well as the delayed ring issue, plus possibly some other issues as well like VM problems and such. This was supposed to be a feature (for nortel) of MTX/NBSS 13.0. Sprint just upgraded it's nortel markets to 12.1. There is usually 6-12 months between software loads so if it's in 13 that would be the timeframe, plus a little time to get everything figured out and set up. I'm not sure where Lucent is with this, but Nortel and them are usually neck and neck with releasing this kinda stuff.
