The growth in Internet usage has been phenomenal over the last decade. During the last few years more and more of this growth has come from mobile broadband access. The most widely used types of mobile broadband access are based on the standards defined by the 3rd Generation Partnership Project (3GPP). This growth, and the introduction of smartphones that are always connected to the Internet, have put a strain on the Internet infrastructure itself. Concretely, this strain is visible in the exhaustion of the Internet Protocol (IP) address space of the currently widely used Internet Protocol version, the Internet Protocol version 4 (IPv4). This dissertation describes how the address exhaustion can be solved in the 3GPP networks using a new version of the Internet Protocol - the IP version 6 (IPv6). IPv6 has been designed by the Internet Engineering Task Force (IETF) to address the shortcomings of IPv4 especially the limits of the address space. The dissertation shows how IPv6 support was designed and introduced to the second and third generation network specifications, how it has evolved through the time and what the current state is in the second, third and and fourth generation cellular networks. The original drivers for IPv6 adoption are also described along the intended scenarios for the transition to IPv6. Finally, the dissertation discusses the current state of the IPv6 adoption in the 3GPP networks in the market place. The research described in this dissertation has been adopted in the 3GPP specifications and implemented in millions of devices and networks all over the globe.
