Hi Uwe, Your document sounds like a very reasonable and useful extension. Just have two related thoughts:
1. Have you considered your cells extension using PID properties? The relevant draft is here: http://tools.ietf.org/html/draft-roome-alto-pid-properties-02#section-4.2 I believe the PID property document provides a solution to both requirements in your document (via Solution B). 2. Since the nodes change cells frequently, do you think this extension would benefit from incremental updates? The incr update document ( http://datatracker.ietf.org/doc/draft-roome-alto-incr-update-sse/) provides the SSE framework, but I am not sure how convenient SSE is to mobile networks.
