TUNNELING INTERNET PROTOCOL PACKETS BETWEEN A GATEWAY SUPPORT NODE AND A MOBILE TERMINAL

摘要

A telecommunications system comprises a gateway support node (GGSN) operable to establish a tunnelling protocol bearer for communicating IPv6 internet protocol packets to and from a user equipment (UE) across an Ipv4 internet protocol packet data network. An address allocation server (DHCP) allocates an IPv6 address to the user equipment for the communication, based on an IPv4 link local address comprising a tunnelling end identifier of the tunnelling protocol bearer which ends at the gateway support node.
