Rel-7 GERAN TR 43.902 "Enhanced Generic Access Networks (EGAN) study" showed that all three technical proposals met the objectives of this GAN Enhancement WID, providing enhancement through different approaches.

GERAN found all options in TR 43.902 as feasible but decided to select the Iu-mode as it can be done completely within TSG GERAN and independently of the I-WLAN or SAE work items. The GAN Iu-mode:

• reduces the complexity for delivery of CS and PS services

• reduces the number of functions in the overhead and latency for PS services

• provides good optimization process for future integration

This work adds the GAN Iu-mode to the GAN specifications, TS 43.318 and TS 44.318.

This work was triggered by GERAN Rel-8 TR 43.903 Study on A-interface over IP (AINTIP) UID_50589.

BSS (Base Station System) over IP is a technical trend in wireless network evolution, which can construct high bandwidth efficient networks. BSS over IP consists of Gb interface over IP and A interface over IP. Gb interface over IP has been specified in Rel-4. As for the A-interface, only the control plane signalling over IP (SIGTRAN) has been introduced in Rel-7.

TR 43.903 compared different AoIP solutions in terms of related criteria, Phase I (general requirements) and Phase II (technical solutions). This work covers the spin-off AoIP specification activity.

Based on the working assumptions agreed in TR 43.903, one technical option was standardized to meet all the migration deployment scenarios defined during feasibility study.
