DISTRIBUTION MECHANISM FOR CONTEXT EXPRESSION EVALUATION

摘要

Method for providing a service in a communication network and service node (10) for such a communication network (1). The service node (10) is arranged to receive and evaluate a request (A). The request comprises an expression being a function of a plurality of elements (B, C), each element relating to data originating from one or more context sources (B, D, E). The service node (10) is, in operation, connectable to the one or more context sources (B, D, E), and further arranged to distribute the evaluation of the expression over two or more execution environments (20, 21, 22) in the communication network (1). The locations of the two or more execution environments (20, 21, 22) is different.
