COMPOSITE SERVICES PROVISION WITHIN A TLECOMMUNICATIONS NETWORK

摘要

The invention refers to a method of correlatinga plurality of service instances by a service composition entity (10), wherein the services are performed by one or a plurality of servers (11, 12) of a telecommunications network. Thereto, the service composition entity (10) performs the steps of invoking a composite service instance corresponding to the service request, and generating a composite service identifier identifying this composite service instance, contacting the one or a plurality of application servers for invoking the plurality of component service instances, wherein the plurality of component service instances are associated to the composite service instance, and sending a first service report (M103, M203) comprising an information about the composite service instance to a service supervision system (13, 23), wherein this information enables the service supervision system (13, 23) to identify reports about the component service instances as being associated to the composite service instance. The invention further proposes a service composition entity for correlating the plurality of service instances, and a service supervision system for monitoring, supervising or controlling the composite service instance.
