What is OSA? A mediator API between Telecom networks and Operator or 3rd Party applications Secure interface between Network Operators and Application Servers. Open standards (specified by the Parlay Group, ETSI and 3GPP). Raises programming abstraction level and allows multi-network applications. Application Server/ Applications OSA API Operator’s (Multi-) Network infrastructure

Bringing Telecoms and IT Together Developed by Operators, Independent Software Vendors, Enterprises and System Integrators Addressing the needs of multiple customer groups Wide Range of Applications Developed using IT technology and tools, using the power of the network Abstract the functions of the network, and simplify development The Parlay/OSA API Common Network Capabilities Fixed, Mobile, 3G, Wi-Fi Open standard API, created by ETSI, Parlay and 3GPP Supporting the same services on multiple networks reduces operating costs, eases migration and increases market share

OSA/Parlay Standardisation OSA specification and standardisation is a joint effort by the following: - 3GPP CT5 - ETSI TISPAN OSA Project - The Parlay Group The objective is to have a single API for the whole developer community OSA = Parlay - All meetings are joint meetings (Joint Working Group) The joint work is based on a common (UML) model http://docbox.etsi.org/tispan/open/osa/osa.htm

OSA/Parlay Standardisation #2 JWG meets 4 times/year: 2 with 3GPP CT WGs, 2 with Parlay Group, c. 20 delegates & 100 Tdocs/meeting Next meeting: 23-26 October 2006, at ETSI Following meeting co-located with 3GPP CT WGs, 5-8 Feb 2007 Using 3GPP working methods, Tdoc numbering, & MCC support Next meeting invite and Tdocs: http://www.3gpp.org/ftp/tsg_ct/WG5_osa_ex-CN5/TSGC5_37_SophiaAntipolis/Docs/

3GPP2 And The Joint Working Group 3GPP2 have adopted OSA/Parlay No separate specifications 3GPP2 requirements brought to JWG 3GPP2 differences listed in annex to 3GPP specs Only scope/references differences to date

Parlay/OSA Terminology: SCSs and SCFs - The Parlay/OSA Gateway consists of several Service Capability Servers (SCS): functional entities that provide Parlay/OSA interfaces towards applications. Interface SCF - Each SCS is seen by applications as one or more Service Capability Features (SCF): abstractions of the functionality offered by the network, accessible via the Parlay/OSA API. SCS - The Parlay/OSA SCFs are specified in terms of interface classes and their methods

OSA: Framework + A Set Of SCFs Application server Application OSA API interface class User Call control framework Location Service Capability Servers Not standardized OSA Internal API WGW HLR CSE Servers WPP E.g. Location server Billing server One of the Parlay/OSA SCSs is called the Parlay/OSA Framework, and is always present, one per network

The Parlay/OSA Framework - control of access to the network - integrity management - discovery of network functionality Client Application 1 2 2 Enterprise Operator Registered Services Framework Call Control Mobility etc 4 3 - Application subscription to services - SCF registration - support of multi-domain

Framework Features Authentication Load & Fault Management Event Notification Service Agreement Management Grouped Contract Management SCF Management Registration Discovery Factory

The Motivation for Parlay X: Web Services for Telecom There is a requirement to publish the capabilities of the network for software developers There is a demand for enterprise applications to exploit the capabilities of the telecom network The Real-Time Enterprise (Gartner) Web Services is a key software development technology: Number of Developers Parlay-X millions Parlay/OSA thousands INAP, SIP thousand Expressive Power Parlay-X defines a set of easy-to-use Web Services, which provide simple and high level access to widely used telecommunications functions Third Party Call Control, Network Initiated Third Party Call Control, SMS, Multimedia Messaging, Payment, Account Management, User Status, User Location

The OSA/Parlay APIs Name Description Usage OSA/Parlay Rich set of telecom APIs, for use in CORBA (C, C++), Java and web services environments. Several hundred methods. Suitable for use by professional software developers. Suitable for developing a pre-paid application. Parlay-X Web Services Set of high-level, simple to use telecom APIs, for use in a Web Services environment. 16 interfaces. Suitable for use by web developers. Designed for use with an Integrated Development Environment (IDE). Suitable for developing a ‘call-me’ button on a web page.
