Abstract: For the purpose of managing a voice communication service in a communication network between a first and at least a second communication terminal, the first and second communication terminals have respective communication identifiers in the communication network. The first and second communication identifiers are associated, at least at a server, with first and second social network identifiers of a social network. A communication request is received, indicating at least the first and second social network identifiers; subsequently, the second communication identifier is identified from the second social network identifier received in the communication request; and, finally, an application notification is transmitted to the second communication terminal on the basis of the second communication identifier. The application notification indicates the first social network identifier.
