In order to manage a change in conditions of using a service associated with a communication in progress established by a user terminal (TU) within its communications network (RT), a server determines that the user's account does not permit the delivery of the service with a change in the conditions of using a service, after the receipt of a first request derived from a network element, said request comprising an identifier of the service regarding the communication and a parameter defining the change in conditions of using the service, and the server transmits to the network element a response containing a code indicating that the delivery of the service is authorized only with other conditions of using the service, in order for the network element to transmit to the server a second request containing another parameter defining another change in conditions of using the service. |
