Providing services to users of PSTN, service resources locatable from SCP using URIs

摘要

Services are provided to users of a public switched telecommunications network (PSTN) that includes a service control subsystem (SCP) by provisioning a server 51 with service resource items that are each associated with a predetermined code. When the SCP receives a service request, a service logic program is run, and the server 51 is accessed to utilise the service resource item corresponding to the request. The service resource items are located using Universal Resource Indicators (URIs). Predetermined code contained in the service request is translated into the URI associated with the service resource, and the URI is used to access the service resource item.
