This technical report considers the way in which Internet Protocol (IP) can be applied in Radio Access Networks (RAN) within 3rd Generation mobile systems. Mobile systems considered specifically for UTRAN being developed by 3GPP (3GPP-UTRAN) for both FDD and TDD modes and the RAN being developed by 3GPP2 for CDMA2000 (3GPP2-RAN). The application of IP may also be considered for other mobile systems where a sharing of a common transport network between 3rd generation mobile and other mobile systems is considered beneficial to operators.
This report builds upon 3GPP, 3GPP2 and IETF to provide directions as to how IP can be applied within Radio Access Networks and to justify the benefits of IP as a transport option. The scope of the work considers the way in which IP can provide benefits to operators in terms of a transport network to support information transfers over RAN internal interfaces and RAN interfaces to the core network. The report also enables IP as an option for the Transport Network Layer supporting the Radio Network Layer protocols within 3GPP-UTRAN, 3GPP2-RAN and possibly other mobile systems.
