Feature: Future GERAN Evolution

GERAN is a result of over a decade of radio interface evolution that is still ongoing. While GERAN is or is being deployed worldwide also in emerging markets, evolving further the GERAN radio interface needs to be studied to ensure not only that the same services are available regardless of the underlying radio technology UTRAN or GERAN, but essentially that service continuity exists across these radio technologies supported by core network evolution e.g. IMS. Such an evolution is also needed to maintain GERAN competitiveness as well as UTRAN competitiveness.

The objective of this work item is to conduct a feasibility study of the means in GERAN to:

    §         Increase spectral efficiency   

    §          Increase capacity and coverage

    §         Increase average data rates

    §         Reduce latency between a mobile station and the GERAN

    §         Enhance service continuity with other RAT

In order to leverage the investments made in GERAN infrastructure, it is necessary to minimize the impacts on it.
