The OSA Gateway Client Interface allows proprietary ASPs to utilise the billing, account management, and functionality of the NCC Voucher and Wallet Server (VWS) using the interface defined in the 3GPP OSA/Parlay specifications.

The OSA specifications define an architecture that enables application service providers to make use of network functionality through an open, standardized interface API.
