摘要

The present invention relates to the computer field networked, there are mentioned a system and method for providing on-demand service to clients requesting a service from a service provider (SP) via an electronic network, in which the client requested service as a possible response for a plurality of third party service provider (TPSP) it is associated in order to provide one or more application specific service (referred to service TPSP referred).
