Composite services provision within a telecommunications network

A method, in a service supervision system hardware server, of supervising a composite service instance being invoked and controlled by a service composition entity, wherein the composite service instance is composed of a plurality of component service instances being performed by one or more application servers, the method comprising:

• receiving, by the service supervision system hardware server, from the service composition entity a first service report comprising information about the composite service instance and a composite service identifier identifying the composite service instance,
• detecting, by the service supervision system hardware server, from the first service report, the composite service identifier together with at least one of the component service identifiers, wherein the at least one component service identifier was inserted by the service composition hardware server after it received the at least one component service identifier from one of the one or more application servers,
• receiving, by the service supervision system hardware server, from one of the application servers, at least one second service reports, each second service report comprising information about the plurality of component service instances and the composite service identifier identifying the composite service instance and component service identifiers identifying each one of the plurality of component service instances together with information about a correlation of the composite service identifier and the component service identifiers, to identify at least one of the second service reports about the plurality of component service instances as being associated with the composite service instance, and
• providing, by the service supervision system hardware server, an instruction to terminate at least one of the plurality of component service instances and corresponding update information.

A service composition hardware server for coordinating a plurality of component service instances being invoked at one or more application servers, the service composition server comprising a non-transitory computer-readable medium encoded with instructions, which, when executed by one or more processors performs the steps comprising:

• receiving a service request for a certain service,
• invoking a composite service instance corresponding to the service request, and generate a composite service identifier identifying the composite service instance,
• contacting the one or more application servers for invoking the plurality of component service instances, wherein the plurality of component service instances are associated with the composite service instance,
• receiving, from one of the one or more application servers, a component service identifier that identifies a corresponding component service instance,
• inserting the component service identifier into the first service report,
• sending a first service report comprising information about the composite service instance and the composite service identifier to a service supervision system, wherein the information enables the service supervision system to identify service reports about the plurality of component service instances as being associated with the composite service instance,
• and
• providing an instruction to terminate at least one of the plurality of component service instances and corresponding update information.

A computer program product comprising a program code stored in a non-transitory computer readable medium configured to:

• receive a service request for a certain service,
• invoke a composite service instance corresponding to the service request, and generate a composite service identifier identifying the composite service instance,
• contact one or more application servers for invoking a plurality of component service instances, wherein the plurality of component service instances are associated with the composite service instance,
• receive, from one of the one or more application servers, a component service identifier that identifies a corresponding component service instance,
• insert the component service identifier into the first service report,
• send a first service report comprising information about the composite service instance and the composite service identifier to a service supervision system, wherein the information enables the service supervision system to identify service reports about the plurality of component service instances as being associated with the composite service instance,
• and
• provide an instruction to terminate at least one of the plurality of component service instances and corresponding update information.
