Method for SIM authentication for notebook WWAN and WLAN hotspots using an external SIM in a phone

Disclosed is a method for subscriber identity module (SIM) authentication for notebook wireless wide area networks (WWAN) and wireless local area networks (WLAN) hotspots using an external SIM in a phone. Benefits include improved performance, improved usability, and improved security.

Background

        � � � � � A SIM card contains the credentials that enable a user to authenticate on a wireless network (WWAN or WLAN). SIM cards are conventionally used by the global system for mobile communication (GSM), general pocket radio service (GPRS), and universal mobile telecommunication system (UMTS) networks.

General description

        � � � � � Disclosed is a method for SIM authentication for notebook WWAN and WLAN hotspots using an external SIM in a phone. Interest is growing in using SIM cards to authenticate access to WLAN networks, particularly where the WWAN and WLAN networks are owned or operated by the same company with a common back-end authentication system.

        � � � � � The key elements of the method include:

•        � � � � Cellular phone that uses a SIM card

•        � � � � Notebook PC with wireless WWAN and/or WLAN capability

•        � � � � Connection between the WWAN and WLAN

Advantages

        � � � � � The disclosed method provides advantages, including:

•        � � � � Improved performance due to � � � � the use of the notebook’s wireless communications hardware with

greater capability than a phone can offer, such as faster reception and transmission, seamless roaming, and improved power utilization

•        � � � � Improved usability du...
