WP1/11 and WP2/11 Chairman highlighted that there is a proposal to organize a one-day Workshop on "Control plane of future networks including IMT-2020. Current issues and the way forward" which may take place back-to-back with the next SG11 meeting (8-17 November 2017). The event is not confirmed yet, however, the dates and potential agenda might be confirmed early September 2017.
The initial intention of the Workshop is to discuss:
- status of current and future ITU activities in control plane of the future networks;
- worldwide practices and perspective on future networks;
- control plane of 5G/IMT-2020.
The workshop also intends to organize a brainstorming session aimed at discussing current signalling/networking issues and areas of standardization of control plane of the future networks, including IMT-2020. In addition, a demo-zone may be organized in parallel to the Workshop.
Participants of WP1/11 and WP2/11 were encouraged to submit their proposals to the Chairmen of WP1/11 and WP2/11 respectively (
