Abstract: A method and device for processing a network service instantiation request received by an orchestration entity using a virtualized network function service. A descriptor of the network service includes at least one reference to an object to be deployed in order to instantiate the network service. When the descriptor of the object is not available at the orchestration entity, the orchestration entity obtains information from the network service descriptor that can be used to identify at least one target entity configured to instantiate the object on instruction from the orchestration entity or to transmit the descriptor of the object to the orchestration entity, and transmits, to one of the at least one target entities, a request to instantiate the object or a request to recover a file comprising the descriptor of the object.

Abstract: A method of resolving by an original network/domain of a telephone number of a called party, belonging to a recipient network/domain. The method includes: a) a calling party, belonging to the original domain dispatches a message using the telephone number of the called party as routing identifier; b) a server of the original domain in charge of routing the message, or a DNS server, produces an interrogation key dependent on the telephone number and on a penultimate domain name; c) a DNS request is sent to a DNS server associated with the penultimate domain; d) the DNS server associated with the penultimate domain performs, by using the interrogation key, a search in a database ENUM associated therewith; e) the search provides at least one record containing a return network/domain including the recipient domain; and f) a DNS request is sent to the return domain.

Abstract: A method and device for sending a request (R) from a requesting machine (H) to a domain name server (1, 2, 3). A prior test of the validity of the destination telephone number (NTEL) of the request (R) is executed automatically and locally to the requesting machine (H) relative to a database (BD) local to said requesting machine (H) in order to forward the request (R) from the requesting machine (H) to the domain name server (1, 2, 3) only if its telephone number (NTEL) passes said test.
