For the gambling term, see Parlay (gambling). A parlay or accumulator is a single bet that links together two or more individual Wagers and is dependent on all of those wagers winning together
For the diplomatic term, see Parley. Parley (parli or parlei is a discussion or conference, especially one between enemies over terms of Truce or other matters

Parlay is an open API for the telephone network (fixed and mobile. Basic principle A traditional landline telephone system also known as "plain old telephone service" (POTS, commonly handles both signaling and audio information )

Parlay Overview

The Parlay Group is a technical industry consortium (founded 1998) that specifies APIs for the telephone network. Year 1998 ( MCMXCVIII) was a Common year starting on Thursday (link will display full 1998 Gregorian calendar) Basic principle A traditional landline telephone system also known as "plain old telephone service" (POTS, commonly handles both signaling and audio information These APIs enable the creation of services by organizations both inside and outside of the traditional carrier environment. In the context of Enterprise architecture, Service-orientation, and Service-oriented architecture, the term service refers to a discretely defined set of In fact, it is hoped that services can be created by IT developers, rather than telephony experts. Information technology ( IT) as defined by the Information Technology Association of America (ITAA is "the study design development implementation support

Important Parlay APIs include: call control, conferencing, user interaction (audio and text messaging), and charging. In Telephony, call control refers to the software within a Telephone switch that supplies its central function The APIs are specified in the CORBA Interface definition language and WSDL. The Common Object Requesting Broker Architecture (CORBA is a standard defined by the Object Management Group (OMG that enables software components written An interface description language (or alternately interface definition language) or IDL for short is a Specification language used to describe a The Web Services Description Language (WSDL pronounced 'wiz-dəl' or spelled out 'W-S-D-L' is an XML -based language that provides a model for describing Web services 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). Code division multiple access ( CDMA) is a Channel access method utilized by various radio communication technologies GSM ( Global System for Mobile communications: originally from Groupe Spécial Mobile) is the most popular standard for Mobile phones in the

In 2003 the Parlay Group released a new set of web services called Parlay X. Parlay X is set of Web service APIs for the Telephone network (fixed and mobile 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. Parlay X is set of Web service APIs for the Telephone network (fixed and mobile 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 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. Java APIs for Integrated Networks ( JAIN) is an activity within the Java Community Process, developing APIs for the creation of Telephony (voice and data

The Parlay Group works closely with ETSI and 3GPP, the Parlay specifications are co-published by all three bodies. The European Telecommunications Standards Institute ( ETSI) is an independent non-for-profit Standardization organization of the Telecommunications The 3rd Generation Partnership Project ( 3GPP) is a collaboration between groups of telecommunications associations to make a globally applicable third generation ( 3G Within 3GPP Parlay is part of Open Services Architecture, so we often use the term Parlay/OSA. The Open Service Access or OSA is part of the 3rd generation mobile Telecommunications network or UMTS.

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. Unified Modeling Language ( UML) is a standardized general-purpose Modeling language in the field of Software engineering. There are then a set of realizations, or mappings, for specific programming environments:

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.

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 an application makes a telephone call, queries the location of a person (or terminal), or charges 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.

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. The Intelligent Network, typically stated as its Acronym IN is a Network architecture intended both for fixed as well as mobile telecom networks SCP or Service Control Point is a standard component of an IN ( Intelligent Networks telephone system which is used to control the service g. , the Telcordia OSP).

Parlay and Web Services

The Parlay X APIs define a set of simple telecom-related Web services. Parlay X is set of Web service APIs for the Telephone network (fixed and mobile A Web service (also Web Service) is defined by the W3C as "a software system designed to support interoperable machine-to-machine interaction Parlay X Version 1, published in May 2003, defines web services for:
