ABSTRACT:
A telecommunications 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 a 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 data network. The user equipment is operable in combination with the gateway support node to form a link local address. The link local address comprises an interface identifier including a tunnelling end identifier of the tunnelling protocol bearer which ends at a gateway support node of the core network part of the packet radio network. An internet protocol address according to the first internet protocol is requested from an address allocation server using the link local address. The user equipment is operable in combination with the gateway support node to receive an allocated internet protocol address according to the first internet protocol, and to communicate with the user equipment using the allocated internet protocol address.Embodiments of the present invention provide a facility for generating a link local address, which can be routed according to the first internet protocol to a server. As such the link local address can be used to acquire an internet protocol address from an address allocation server according to the first internet protocol. The acquired address can therefore be used to communicate internet protocol data, replacing the link local address with the acquired address of the user equipment.
