Abstract: Some embodiments provide a system for authorization and authentication of an unlicensed mobile access (UMA) subscriber. The system includes an UMA network controller (UNC) which is communicatively coupled to a licensed wireless communication system. The system also includes an access point (AP) that serves a wireless local area network (WLAN). The system further includes a mobile station (MS) that is communicatively coupled to the AP and the licensed wireless communication system. The system also includes an authentication server that is communicatively coupled to the UNC. The authentication server authenticates a UMA subscriber for accessing an unlicensed mobile access network (UMAN) that includes the UNC and the AP. [Some embodiments define an interface between the UNC and the authentication server uses Remote Access Dial-In User Service (RADIUS) protocol. In some embodiments, the authentication server is an Authorization, Authentication, and Accounting (AAA) server.

Abstract: Some embodiments provide a first interconnect circuit for accessing stored data in a reconfigurable IC. The reconfigurable IC has at least one reconfigurable circuit and a set of storage elements for storing several data sets for the particular reconfigurable circuit. The first interconnect circuit includes second, third, and fourth interconnect circuits, where the fourth interconnect circuit connects to outputs of the second and third interconnect circuits. The second and third interconnect circuits connect to the storage element sets to provide data sets to the fourth interconnect circuit, which, in turn, provides the received data to the particular reconfigurable circuit. The fourth interconnect circuit operates at a different rate than the second and third interconnect circuits. In some embodiments, the stored data sets are configuration data sets for configuring the articular reconfigurable circuit.

Abstract: Some embodiments provide a configurable IC that includes several configurable tiles. The configurable tiles include several interior tiles within the interior of an arrangement of configurable tiles. The arrangement has several sides that define the exterior boundary of the arrangement. In some embodiments, each configurable interior tile includes a set of configurable logic circuits, a set of configurable input-select circuits for selecting inputs to the configurable logic circuits, and a set of configurable routing interconnect circuits for routing signals between the configurable logic circuits. The set of configurable input-select circuits in each interior tile has a set of inputs that are supplied by a set of asymmetric locations in the configurable IC.
