27、s given in ES 202 391-1 2 apply. 4 Detailed service description Currently, in order to perform a third party call in telecommunication networks we have to write applications using specific protocols to access Call Control functions provided by network elements (specifically operations to initiate a
28、call from applications). 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. Develop
29、ers must have advanced telecommunication skills to use Call Control OSA interfaces. In this clause we describe a Parlay X 2 Web Service, Third Party Call, for creating and managing a call initiated by an application (third party call). The overall scope of this Web Service is to provide functions to
30、 application developers to create a call in a simple way. Using the Third Party Call Web Service, application developers can invoke call handling functions without detailed telecommunication knowledge. Figure 1 shows a scenario using the Third Party Call Web Service to handle third party call functi
31、ons. The application invokes a Web Service to retrieve stock quotes and a Parlay X 2 Interface to initiate a third party call between a broker and his client. In the scenario, whenever a particular stock quote reaches a threshold value (1) and (2), the client application invokes a third party call b
32、etween one or more brokers and their corresponding customers to decide actions to be taken. After invocation (3) by the application, the Third Party Call Web Service invokes a Parlay API method (4) using the Parlay/OSA SCS-CC (Call control) interface. This SCS handles the invocation and sends a mess
33、age (5) to an MSC to set-up a call between user A and user B. In an alternative scenario, the Parlay API interaction involving steps (4) and (5) could be replaced with a direct interaction between the Third Party Call Web Service and the Mobile network.

43、setup, end and determine the status of a call. 8.1.1 Operation: makeCall The invocation of makeCall requests to set-up a voice call between two addresses, callingParty and calledParty, provided that the invoking application is allowed to connect them. Optionally the application can also indicate the
44、 charging information (charging). By invoking this operation the application may monitor the status of the requested call. The returned parameter, callIdentifier, can be used to identify the call. In order to receive the information on call status the application has to explicitly invoke getCallInfo
