Each terminal wishing to access a communication service implemented in a communication network transmits an identifier of subscription to this service during a phase of registration (3.1; 3.2) in the network. With each service subscription identifier is associated a call identifier for making it possible to call the terminal registered via the network. A system (1.2, 1.3) intended to register at least one terminal (1.4) from among a plurality of terminals (1.3; 1.4) in a telephony network comprises means of dynamic changing of service subscription identifier (3.11, 3.12, 3.13) and of associated call identifier (3.4, 3.5, 3.6), for at least one of said terminals, and means for reregistration (3.15) in said network of each terminal for which the service subscription identifier and the associated call identifier have been dynamically changed. |
