IPRs essential or potentially essential to the present document may have been declared to ETSI. The information

pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found

in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in

respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web

Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web

This ETSI Standard (ES) has been produced by ETSI Technical Committee Telecommunications and Internet

converged Services and Protocols for Advanced Networking (TISPAN), and is now submitted for the ETSI standards

The present document is part 3 of a multi-part deliverable covering Open Service Access (OSA); Parlay X

The present document has been defined jointly between ETSI, The Parlay Group (http://www.parlay.org) and the 3GPP.

The present document is part 3 of the Stage 3 Parlay X 2 Web Services specification for Open Service Access (OSA).

The OSA specifications define an architecture that enables application developers to make use of network functionality

References are either specific (identified by date of publication and/or edition number or version number) or

the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the

For the purposes of the present document, the abbreviations given in ES 202 391-1 [2] apply.

Currently, in order to determine the handling of a subscriber initiated call in telecommunication networks we have to

write applications using specific protocols to access Call Control functions provided by network elements. This

approach requires a high degree of network expertise. We can also use the OSA gateway approach, invoking standard

interfaces to gain access to call control capabilities, but these interfaces are usually perceived to be quite complex by

application IT developers. Developers must have advanced telecommunication skills to use Call Control OSA

In this clause we will describe a Parlay X 2 Web Service, Call Notification, for handling calls initiated by a subscriber

in the network. A (third party) application determines how the call should be treated. The overall scope of this Web

Service is to provide simple functions to application developers to determine how a call should be treated. Using the

Web Services, application developers can perform simple handling of network-initiated calls without specific Telco

Incoming call handling: A subscriber receives a call while he is logged-on to the Internet. Since this occupies his

telephone connection, he is regarded as busy by the network. The subscriber has an application that is invoked when

somebody tries to call him while he is busy. The application provides the subscriber with a list of choices on how to

handle the call (e.g. route the call to voicemail, redirect the call to a secretary, reject the call). Based on the response of

the subscriber the call is handled in the network. Alternatively, the call is re-routed or released depending on the
