ADAPTIVE CONTEXT SOURCE UPDATE MECHANISM

摘要

Method for providing a service in a communication network (1), and service node (10) arranged to execute that service. The service node (10) is arranged to receive and evaluate a request from the service, the request comprising an expression having multiple elements. Each element relates to data originating from one or more context sources (B, D, E), which can provide the data to the service node (10), e.g. using context source proxies (B', D', E'). Switching between a request based mechanism and an event trigger based mechanism of one of the context sources (B, D, E) is executed based on a predetermined network parameter.
