  • the present invention relates generally to the field of wireless systems that allow mobile devices to authenticate and register to wireless networks (e.g. cellular networks, WiFi networks, etc.) using access control techniques based on Subscriber Identity Module (SIM) devices.
  • wireless networks e.g. cellular networks, WiFi networks, etc.
  • SIM Subscriber Identity Module
  • access control techniques provide the essential services of authorization, identification and authentication, access approval, and accountability where: authorization specifies what a subscriber can do; identification and authentication ensure that only legitimate subscribers can log on to a system; access approval grants access during operations, by association of subscriber with the resources (like services, applications, content) that they are allowed to access, based on the authorization policy; accountability identifies what a subject did.
  • access control clients are logical entities embedded in hardware / software modules.
  • access control clients include:
  • USB Universal Subscriber Identity Module
  • the Removable Universal Identity Module (RUIM) application allowing access control procedures on Code Division Multiple Access (CDMA) networks
  • the Interworking Wireless Local Area Network (l-WLAN) application allowing access control procedures on WiFi networks tightly coupled to cellular networks, in order to provide "WiFi offloading" of cellular network data traffic
  • SIM card media such as the Universal Integrated Circuit Card (UICC); such card media are generally known as "Smart Cards", or - more commonly - “SIM cards”. Whilst SIM card offer several benefits in terms of security, they have limitations in terms of network access; in general, SIM cards contain a unique International Mobile Subscriber Identifier (IMSI), which binds the access control client to a single associated network.
  • IMSI International Mobile Subscriber Identifier

  • the 'Multi- IMSI' SIM cards impose a specific, predictable behavior on the supporting mobile device: such behavior can be ensured only by operating and maintaining complex and expensive databases.
