An intelligent network comprises service switching points (SSP), where the call switching is made and where data relating to calls and signals indicating various events relating to the calls are generated and service control points (SCP) connected to the service switching points (SSP) to receive call data and event signals and for controlling switching points. A service control point (SCP) comprises a service control function (SCF) for processing events relating to calls, the service function (SCF) comprising in turn predefined building blocks or control types, which are executed for specific events relating to a call. In order to provide an interface to the exterior allowing some customer design or customer programming, in particular to servers (CSP_1, CSP_2. ...) comprising some service function (CSF_1, CSF_2, ...) which is supplied by the customer running the server, the servers are connected to the network only at a single service control point (SCP). The service control function (SCF) in this service control point (SCP) comprises therefor a remote procedure building block (RPROC), which transfers, when it is executed for an event relating to call, data relating to the call to a data buffer. The function (CSF_1, CSF_2, ...) in the server accesses the data buffer through a remote procedure function (RPF_1, RPF_2) to process the data and store the data in another data buffer. The remote procedure building block (RPROC) then accesses this data buffer and makes the processed data available to other building blocks as call data. <IMAGE> |
