In a communication system (SYS) a first network (IN) which is the IPv4 Internet, a second network (GV6-1) which is a IPv6 network, a third network (GV6-2) which is a IPv6 network, and a fourth network (GV4) which is a global IPv4 network are interconnected through respective gateways (GW1, GW2, GW3). The invention allows a communication between a mobile host (MH) whose home network is the second network (GV6-1) and which has roamed to the fourth network (GV4) and a corresponding host (CH) registered in the third network (GV6-2). The invention comprises a registration and communication method for the communication system (SYS). |
