IPv6 in 3rd Generation Partnership Project (3GPP)
Evolved Packet System (EPS)
Abstract
The use of cellular broadband for accessing the Internet and other
data services via smartphones, tablets, and notebook/netbook
computers has increased rapidly as a result of high-speed packet data
networks such as HSPA, HSPA+, and now Long-Term Evolution (LTE) being
deployed. Operators that have deployed networks based on 3rd
Generation Partnership Project (3GPP) network architectures are
facing IPv4 address shortages at the Internet registries and are
feeling pressure to migrate to IPv6. This document describes the
support for IPv6 in 3GPP network architectures.
