IPv6 in 3GPP networks satisfying IETF's recommendations
3GPP PS (Packet Switched) domain Standard states the usage of IPv6 as its network protocol to compensate the shortage of Internet address and to use the enhanced network protocol functions. In case of the current IPv6 usage in 3GPP packet domain standards, they have unique IPv6 address allocation scheme which is somewhat different from the one of IETF due to its 3G equipments and packet network elements. Meanwhile, IETF presents 'recommendations to 3GPP networks (RFC3314 [2])' to satisfy compatibility between IETF IPv6 and IPv6 of 3GPP networks and to lift up the IPv6 capabilities. In this situation, this document provides a new IPv6 address allocation scheme in 3GPP networks satisfying IETF' recommendations. Provided scheme keeps rules of recommendations of IETF standards and guarantees backward compatibility with the legacy 3GPP IPv6 autoconfiguration.
