System and method providing interoperability between cellular and other wireless systems
View Patent ↗A method and corresponding apparatus for providing a cellular subscriber with access to a WLAN are provided. They involve identifying a multimode mobile terminal, which corresponds to the subscriber and the WLAN from an access request. Based on the identification, the WLAN is authorized to provide the mobile terminal with access. The mobile terminal is then provided with access to the WLAN as a cellular subscriber and enables interoperability between the two networks. For example, the subscriber does not have to supply a credit card to pay for WLAN access directly. Instead, the subscriber pays a cellular network provider, and, in turn, the cellular network provider pays a WLAN provider for the access.
