SYSTEM UND VERFAHREN ZUR ÜBERMITTLUNG VON INTERNETPAKETDATEN VIA PAKETFUNKNETZE

摘要

A telecommunications system for communicating internet packet data in accordance with a first internet protocol (IPV6) via a packet radio network operable in accordance a second internet protocol (IPV4). The system comprises a user equipment operable to request a bearer for communicating internet protocol data according to the second internet protocol (IPV4) to and from a gateway support node of the packet radio network. The gateway support node is operable to establish a tunnelling protocol bearer for communicating the internet packet data to and from the user equipment across the packet radio network. The user equipment is operable in combination with the gateway support node to form an address which is compatible with the first internet protocol (IPv6). The address includes an interface identifier having a tunnel endpoint identifier of the tunnelling protocol bearer which ends at the gateway support node of the packet radio network. The internet packet data is communicated to and from a correspondent node via the gateway support node and the established bearer using internet protocol address which is compatible with the first internet protocol (Ipv6). Systems according to the present invention are arranged to generate an address, which is compatible with a first internet protocol which can be used to communicate internet packet data via a packet radio network which has been arranged to support internet packets data according to a second internet protocol. The first internet protocol may be the IPv6 and the second internet protocol may be IPv4.
