The invention relates to a system for controlling access to a service provided by a communication network operator. According to the invention, such a service can be accessed via a plurality of private network access terminals (HG1, HG2, HG3), such as residential gateways, which are aggregated in an access network dedicated to the service. A separate localisation zone (LA1, LA2, LA3) is associated with each of the private terminals (HG1, HG2, HG3). During a localisation updating procedure initiated by a user terminal, at least one controller (11) associated with the private terminals can implement means for determining the category to which the user belongs, and means for controlling the access of the user terminal to one of the private terminals, according to the determined category, said means being able, in the event of refusal of access of said user terminal to one of said private terminals (HG1, HG2, HG3), to send a refusal message to the terminal, with a reason for rejection which depends on the category determined for the user. |
