Abstract
Abstract Delivery of dual-mode GSM/WiFi voice and data services to a consumer with support for transparent network registrations and handovers between GSM and WiFi networks. Aspects include transparently and wirelessly automating call redirection procedures of calls and data (e.g., SMS messages) to legacy telephone devices, to GSM handsets via broadband, and to VoIP devices via broadband. An indoor network is treated as a pseudo visitor PLMN (VPLMN) by the home PLMN (HPLMN) which does not require GSM radio coverage in an indoor network. This innovation provides a means for automating a process of redirecting a subscriber's calls from the GSM network to the subscriber's home network, and can utilize a Bluetooth access point to provide a beacon signal for triggering redirection.
