A METHOD FOR OVERLAYING ONE WIRELESS NETWORK SYSTEM OVER ANOTHER WIRELESS NET WORK SYSTEM OVER ANOTHER WIRELESS NETWORK SYSTEM

摘要

a) Usage of Registration Zones of the existing 2G network to identify whether MS is in preferred (3G) RAT's area; b) Once MS finds that it is in a 2G registration zone where there is a deployment of preferred (3G) RAT NETWORK, then MS can trigger RF power measurements of preferred (3G) RAT. c) If RF channel power of preferred (3G) RAT is above some threshold consistently for some time, then MS can switch to preferred (3G) RAT NETWORK. No need to perform periodic measurements for preferred NETWORK when MS is camped on non-preferred NETWORK and this results in
