Abstract
A selective Global Service Redirection mechanism allows a service provider, for instance, to instruct only CDMA2000 (MOB_P_REV=6) mobiles to access specific carrier that is deployed to support advanced services known as 3G services. In another embodiment, data-only CDMA2000 mobiles are instructed to access specific carrier that is optimized to support high speed data services. Additionally, data-only CDMA2000 mobiles may be instructed to access a specific carrier that is optimized to support high speed data services. Pre-CDMA2000 mobiles (MOB_P_REV<6) are redirected by a conventional Global Service Redirection Message to another carrier, while CDMA2000 mobiles (MOB_P_REV=<6) are instructed to ignore this redirection.
