A subscription to a service provided in a communication network is managed by a first terminal. The communication network includes a second terminal, and the service includes transmission of digital information. An access is capable of obtaining a maximum rising throughput value allocated to the first terminal and a descending throughput value allocated to the second terminal. On the access of the network, an access request is received for subscribing the second terminal to the service provided by the first terminal. Then, a decision about access to or refusal of subscription of the second terminal is made on the basis of the maximum rising throughput value allocated to the first terminal and on the basis of the descending throughput value allocated to the second terminal. And finally, a response indicating the decision is sent.
