An embodiment of the present invention provides a mobile station to communicate with an application service provider (ASP) in a wireless network using a Universal Services Interface (USI) comprising, memory, one or more processors and a transceiver, to store some or all USI context as required by the ASP and wherein when a user accesses the ASP, the USI client inserts relevant USI context as part of an ASP request message and in order to fetch the USI context of the MS, a USI proxy sends the USI context request to a USI server and the USI server sends a USI context response back to the USI proxy which contains the USI context for the MS.
