OSA: Open System Architecture
Open System Architecture (OSA) is part of the 3rd generation (3G) UMTS mobile telecommunications network. OSA describes how services are architected in a UMTS network. The OSA provides APIs to access the network functions like authentication and authorization of the user. The APIs are guaranteed to be secure, independent of vendor specific solutions and also independent of programming language by use of Object Oriented techniques like CORBA, SOAP etc. Various services like VPN, conferencing and many more unknown services can be implemented with the help of these APIs. The standards for OSA are being developed as part of the 3rd Generation Partnership Project (3GPP).
