Parlay Overview

The Parlay Group is a technical industry consortium (founded 1998) that specifies APIs for the telephone network. These APIs enable the creation of services by organizations both inside and outside of the traditional carrier environment. In fact, it is hoped that services can be created by IT developers, rather than telephony experts. 1998 (MCMXCVIII) was a common year starting on Thursday of the Gregorian calendar, and was designated the International Year of the Ocean [1]. // Coated in ice, power and telephone lines sag and often break, resulting in power outages. ...

The telephone is a telecommunications device which is used to transmit and receive sound (most commonly speech) across distance. ... Wikibooks has more about this subject: Marketing In economics and marketing, a service is the non-material equivalent of a good. ... Information technology (IT), as defined by the Information Technology Association of America (ITAA)is: the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware. ...

Important Parlay APIs include: call control, conferencing, user interaction (audio and text messaging), and charging. The APIs are specified in the CORBA Interface definition language and WSDL. The use of CORBA enables remote access between the Parlay gateway and the application code. A set of Java mappings allow the APIs to be invoked locally as well. A major goal of the APIs is to be independent of the underlying telephony network technology (e.g. CDMA vs GSM vs landline SS7). In telephony, call control refers to the software within a telephone switch that supplies its central function. ... Web conferencing is used to hold group meetings or live presentations over the Internet. ... In computing, Common Object Request Broker Architecture (CORBA) is a standard for software componentry, created and controlled by the Object Management Group (OMG). ... An interface description language, (alternatively interface definition language) (IDL), is a computer language or simple syntax for describing the interface of a software component. ... The Web Services Description Language (WSDL, pronounced wiz-dull or spelled out, W-S-D-L) is an XML-based language that provides a model for describing Web services. ... Java is an object-oriented applications programming language developed by Sun Microsystems in the early 1990s. ... General Information Generically (as a multiplexing scheme), code division multiple access (CDMA) is any use of any form of spread spectrum by multiple transmitters to send to the same receiver on the same frequency channel at the same time without harmful interference. ... Not to be confused with Get Some Mates The Global System for Mobile Communications (GSM) is the most popular standard for mobile phones in the world. ... Signalling System #7 is a set of protocols defined by ITU-T, specifically in the Q.7* set of documents, used to set up telephone calls. ...

In 2003 the Parlay Group released a new set of web services called Parlay X. These are a much simpler set of APIs intended to be used by a larger community of developers. The Parlay X web services include Third Party Call Control (3PCC), Location and simple payment. The Parlay X specifications complement the more complex yet powerful Parlay APIs. Parlay X implementations are now (Sept 2004) in commercial service from BT and Sprint. Parlay X is a set of telecommunications Web services. ... Parlay X is a set of telecommunications Web services. ...

Parlay work historically stems from the TINA effort. Parlay is somewhat related to JAIN, and is currently (early 2003) completely unrelated to the Service Creation Community. TINA is an acronym for Telecommunications Information Networking Architecture. ... JAIN is an activity within the Java Community Process, developing APIs for the creation of telephony (voice and data) services. ...

The Parlay Group works closely with ETSI and 3GPP, the Parlay specifications are co-published by all three bodies. Within 3GPP Parlay is part of Open Services Architecture, so we often use the term Parlay/OSA. The European Telecommunications Standards Institute (ETSI) is a standardization organization of the telecommunications industry (equipment makers and network operators) in Europe, with worldwide projection. ... This article or section does not adequately cite its references or sources. ... The Open Services Architecture (OSA) is part of the 3rd generation mobile telecommunications network or UMTS. OSA describes how services are architected in an UMTS network. ...

Parlay Technology

The objective of Parlay/OSA is to provide an API that is independent of the underlying networking technology and of the programming technology used to create new services. As a result the Parlay/OSA APIs are specified in UML. There are then a set of realizations, or mappings, for specific programming environments: API may refer to: In computing, application programming interface In petroleum industry, American Petroleum Institute In education, Academic Performance Index This page concerning a three-letter acronym or abbreviation is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ...

In the field of software engineering, the Unified Modeling Language (UML) is a standardized specification language for object modeling. ...

Parlay Framework

It is important for a telecom network operator to know that any applications using the Parlay API cannot affect the security or integrity of the network. API may refer to: In computing, application programming interface In petroleum industry, American Petroleum Institute In education, Academic Performance Index This page concerning a three-letter acronym or abbreviation is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ...

The role of the Parlay/OSA Framework is to provide a way for the network to authenticate applications using the Parlay/OSA API. The Framework also allows applications to discover the capabilities of the network, and provides management functions for handling fault and overload situations.

Parlay APIs

The Parlay service APIs, are how application make telephone calls, or query the location of a person (or terminal) or charge for the download of a ringtone.

Implementing Parlay

The Parlay/OSA specifications define an API, they do not say how the API is to be implemented. API may refer to: In computing, application programming interface In petroleum industry, American Petroleum Institute In education, Academic Performance Index This page concerning a three-letter acronym or abbreviation is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ...

The typical Parlay/OSA implementation adds a new network element - the Parlay/OSA Gateway. The Gateway implements the Framework. It may implement the individual service APIs, or may interact with other network elements such as switches to provide individual service capabilities such as call control or location. Some vendors treat the Parlay/OSA Gateway as a stand-alone network element (e.g., the Ericsson NRG, AePONA Causeway, HERIT Parlay/Parlay X Gateway), others include this function in an IN Service Control Point (e.g., the Telcordia OSP). The Intelligent Network or I.N., as it is more commonly referred to, is a network architecture for both fixed and mobile telecommunication networks. ... SCP or Service Control Point is a standard component of IN (Intelligent Networks) that is used to control the IN Service. ...

Parlay and Web Services

The Parlay X APIs define a set of simple telecom-related Web services. Parlay X Version 1, published in May 2003, defines web services for: Parlay X is a set of telecommunications Web services. ... The W3C defines a Web service[1] as a software system designed to support interoperable Machine to Machine interaction over a network. ... Parlay X is a set of telecommunications Web services. ...
