Abstract

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.
