“ Whilst the basic SIP protocol is relatively straightforward, its extension for IMS (ISC) is far more complex. (As an evolving signaling protocol for the next generation networks it has been referred to as ‘SS8’). For some value added applications SIP is inappropriate and a higher-level abstraction is needed.

In the IT industry, Service-Oriented Architecture (SOA) is often implemented using the key web-services technologies (SOAP, WSDL and XML). The Parlay Group has created a similar set of web service interfaces to general telecom capabilities known as Parlay X. Parlay-X Web Services define a set of telecommunications oriented web-services, which are part of 3GPP Release 6.

Parlay-X in effect creates a bridge for the operator from the Service-Oriented Architecture used by developers and large enterprise customers, to the IMS. “ Page 23




Future Considerations

• Wireless/Wireline Integration and Advanced Voice Services– Call Management– Call Centers– Virtual PBX

• IMS– Parlay as the Network Abstraction Layer– SIP Services exposed to third parties in a secure, controlled manner– Services bridging circuit switched and SIP networks

• Mobile Virtual Network Operators (MVNO)– Service Delivery Platforms provide a mechanism for MVNO to offer

differentiated services

• What Third Party Developers need:Help in marketing their services A business infrastructure to create a cash flow

Operator as Retailer of ServicesOperator as Retailer of Services


Where to use Web Services?

• Use Web ServicesNew applications across multiple organizational domains, where requirements for availability are low and there is little customization of the provider service enablers.

• Use Traditional distributed programmingWhere high levels of integration are required for high availability, multi-step transactions, ongoing shared state, or real-time performance.

• Hybrid ApplicationsCore telecom services may be exposed to external entities as web services. Web services can make available network information such as customer configuration or presence and location. They may provide service interfaces for internal applications like charging and messaging services to external application developers.Web services may be used by core telcom applications to alter call processing (forward to voicemail when calendar shows callee is in a meeting) in so far as their limitations can be bounded by time-outs and default actions.

• Service EvolutionIMAP, Corba, EDI, LDAP and the like will all have web-services alternatives, usually to enable application blending across domains.Applications requiring more complex authentication, transaction or session state, or complex data models are likely to remain with purpose-built protocols.
