Title (EN) A METHOD FOR PROVIDING PRIVACY BY NETWORK ADDRESS TRANSLATION
(FR) PROCEDE POUR ASSURER LA CONFIDENTIALITE PAR TRANSPOSITION D'UNE ADRESSE RESEAU
Abstract:
(EN) A call between a first network associated with a calling party and a second network associated with a called party is connected. The source address for packets associated with the call are translated. The packets are sent from the calling party to the called party without the called party receiving the source address that indicates at least one from the group of a logical identity of the calling party and a geographical identity of the calling party.
(FR) Une communication est établie entre un premier réseau associé à un appelant et un second réseau associé à un appelé, l'adresse source des paquets associés à cette communication étant transposée. Ces paquets sont envoyés à l'appelé par l'appelant, sans que cet appelé ne reçoive ladite adresse source indiquant l'identité logique ou l'identité géographique de l'appelant.
