1. A method for managing the mobility of a mobile network in a Proxy Mobile Internet Protocol (PMIP) environment operating under the Dynamic Host Configuration Protocol (DHCP) protocol, said mobile network comprising a mobile router in communication with at least one user device, the method comprising the following steps:
receiving a DHCP Request message requesting a mobile network prefix, the message containing a unique DHCP identifier to identify the requesting mobile router (DUID); allotting a mobile identifier value (MNID) to the unique DHCP identifier; generating a DHCP Relay-Forward message requesting a mobile network prefix, the message containing the allotted value of the mobile identifier (MNID); receiving a DHCP Relay-Reply response message containing an allocated mobile network prefix and the value of the mobile identifier (MNID); restoring the value of the unique DHCP identifier; and transmitting a DHCP Reply response message containing the unique DHCP identifier of the requesting mobile router (DUID) and the allocated mobile network prefix.
