A processing method for use in a communications network to process a service request relating to a user. During a first stage referred to as a “detection” stage an interrogation server interrogates a subscriber server in order to obtain an identifier of a nominal registration server to which it transfers the service request, and in the event of the transfer failing, it interrogates the subscriber server in order to obtain the capabilities that a registration server needs to possess in order to be capable of delivering the services authorized for the user. Once the nominal registration server is considered to be unreachable, a second stage is started, referred to as an “optimization” stage, during which a single transfer is made to registration servers of the service request relating to a user. |
