Abstract
A cellular service provider network includes a subscriber database that associate identifiers from the cellular mobile devices (e.g., IMSIs stored within SIM cards of the devices) with layer three (L3) network addresses currently assigned to the cellular mobile device by the cellular network for providing data service to the cellular mobile devices. The subscriber database further stores identifiers for wireless local area network (WLAN) interfaces of the cellular mobile devices. The cellular service provider network includes a server coupled to a layer two (L2) network having a plurality of wireless access points. In response to access requests from the cellular mobile devices over the L2 network, the server queries the subscriber database of the cellular service provider network and assigns the network addresses to the cellular mobile devices by matching L2 network addresses specified within the access requests with the identifiers of WLAN interfaces stored in the subscriber database.
