Abstract: A technique of controlling access by a client entity to a service in a communications network. Processing modules are interconnected in the network in order to supply the service to the client entity. A processing module implements an individual function of a chain of individual functions associated with the service. The access method includes the following steps implemented by an access control device associated with an access node giving access to the service, the device being referred to as a main device: receiving a chain of processing modules from the access node; sending, to a secondary access control device associated with a processing module of the chain, a request to access the processing module under consideration, the request including an access token negotiated between the main device and the client entity; receiving a response to the access request from the secondary device; and notifying the access node of the response.
