Service deployment architecture

The invention relates to a method of making communication or information services via a telecommunication network available to service users. More particularly it relates to a method of providing interprocess communication between service providers and service users via a notification and synchronization entity that has access to service nodes via which service agents are executable. The invention is directed to a method of making communication or information services via a telecommunication network available to service users. The method entails receiving from agent initiators registrations for service offer references, receiving from a service provider for a service a service offer notification comprising a service offer reference, making available to those agent initiators who have registered themselves under the received service offer reference, the service offer notification, which is usable for obtaining a service agent for the service, and in the case of initiation of the service agent, receiving from the service agent at least one registration for a service subscription reference, receiving from the service users service subscription notifications, comprising a service subscription reference, making available to those service agents who have registered themselves under the received service subscription reference, the service subscription notification, which is at least in part usable as input for the service agent for the service.
