Feature:     IP transport in the UTRAN

The Release 2000 (later Rel-4 and Rel-5)  work plan includes, as an option, an all-IP transport architecture aimed at allowing operators to deploy IP technology to deliver 3rd generation services.

The foreseen benefits of the introduction of IP as transport technology inside the UTRAN are:

• To give the operator the option to use IP transport as an alternative to AAL2/ATM transport within UTRAN.

• In which networks, or parts of network, the IP option is beneficial over the AAL2/ATM option will vary between different operators, e.g. depending on existing transport network infrastructure, other applications using the same transport, available physical links, etc.

• A consistent approach allowing for end-to-end IP transport solutions.

The purpose of this new work task is to enable the usage of IP technology for the transport of signalling and user data over Iu, Iur and Iub in the UTRAN. This work task is only related to the transport aspects.

Work to be led by R3.
