The purpose of this TR is to help the TSG RAN WG3 group to specify the changes to existing specifications, needed for the introduction of "IP Transport" option in the UTRAN for Release 5. Some mobile operators require a UTRAN transport solution for IP as an alternative to ATM. This is partly due to the following reasons:
  • IP is developing to allow the support of a mix of traffic types and to support low speed links.
  • The popularity of the Internet/World Wide Web and corporate LANs puts price pressure on IP networking equipment.
  • IP is the technology to the "desktop" (terminals) so most applications will be based on IP.
  • Operation and maintenance networks will be based on IP. To have networks with homogeneous technology can save management and operations costs.
  • IP, like ATM, is a packet-switched technology and provides the opportunity to use transport resources in an efficient manner.
  • IP is Layer 2 independent.
  • Autoconfiguration capabilities.
  • Dynamic update of routing tables.
It is clear that there will be IP data traffic in the mobile networks. It should be a matter of an operator's choice whether IP or ATM is used in the transport network to carry the various types of traffic from the circuit and packet domains.
