Multi-mode interoperable mobile station communications architectures and methods

摘要

A Multi-mode mobile wireless communications device architecture ( 200 ) including an application layer ( 210 ), a services layer ( 220 ) interfacing the applications layer, a multi-mode layer ( 230 ) interfacing the service layer, and a hardware layer ( 240 ) interfacing the multi-mode layer. The multi-mode layer includes first and second interoperable radio access technologies, for example W-CDMA UMTS and GSM/GPRS technologies.
