JEM for 3GPP2 Vision, San Diego, July 12-13, Conclusion IP 2 continues to study long-term all IP requirements and its architecture. As an uptream activity, IP 2 is contributing to global organizations / forums (i.e., WWRF) with its study results and findings. Open issue is how to achieve harmonization on all-IP network beyond IMT IP 2 wishes to cooperate toward this goal.
