Abstract:
LTE is an all-IP based 3GPP architecture, meaning that the transport in the network is based on IP, as post-Release 5 UMTS, unlike the former 3GPP architectures like GSM, Release 5 UMTS whose transport is based on ATM. Hence, fore-runners in this field have deployed with IPv4 as the basic protocol for addressing and transport, although the deployment of LTE is still in its initial phase and trial runs are executed by various operators. But findings and results prove that the exhaustion of IPv4 will not make it possible anymore IPv4 addresses for this new technology to take its full fledge. Hence, this led to the necessity of considering IPv6 as the protocol for addressing and transport. The primary reason to perceive IPv6 is its scalability feature meaning that it supports large address spacing. Now, with this in mind, when IPv6 is considered in the LTE architecture, the possible impacts on the network are investigated in depth in this paper. This is began by considering IPv6 in transport and application level in the different network entities in the LTE architecture like e-Node B, Serving-GW, PDN-GW and the transition impacts from IPv4 to IPv6 is analyzed. Based on preliminary empirical evaluation, our conclusion is that despite the fact that IPv6 offers large address spacing, the fact that the size of the IPv6 header is 20 bytes more than the header of IPv4, leads to complications as well.
