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.

A codec negotiation method may include issuance by a first terminal, belonging to a first IP domain/network, of an offer message specifying, a list of codecs referred which said first terminal is capable of using for communicating with a second terminal, belonging to a second IP domain/network. The offer may be intercepted by a transit device situated on the signaling path between the first and second domains/networks. The transit device may determine a revised offer, and send the revised offer to the second terminal. The second terminal may determine a response including a list of more than one codecs that are contained in the revised offer and that the second terminal is capable of using, and sends the response to the transit device. The transit device may determine a provisional revised response, so as to comply with a certain priority criterion selected by the operators of the domains/networks in question.
