Dear ad hoc members, I’m forwarding an email from Yong
Sun to the list. I’ve uploaded the document that he sent to the following
location. http://dot16.org/CSUpload//upload/temp_db/C80216j%2d06_UMAHtemp_Disaster_event_NRS.ppt. The comments that Yong makes are editorial
in nature. I agree with him and think that we should make the changes and incorporate
the diagram that he has provided. Jerry From: Yong Sun
[mailto:Sun@toshiba-trel.com] Dear Jerry and all, Might I comment on the
‘Temporary Coverage Usage Model’: the first example of
‘Emergency/Disaster Recover’ said that:
‘In this case fixed infrastructure may have been destroyed or coverage is
required in areas that are not serviced by fixed infrastructure
deployments’
And then, it said that: ‘The detailed usage
scenarios in this model are similar to those of the fixed infrastructure usage
model’ It is a little bit
mismatched when read it through: in case that the entire fixed infrastructure
were destroyed, how to use a fixed infrastructure (or similar fixed
infrastructure) – do we suggest/require to re-built a fixed
infrastructure on disaster site and treat the new-set of fixed relay as nomadic
relay? – even though it can be fully understood from the first sentence
of the section that nomadic relay is employed. Anyway, I suggest rewording this
part just making it clearer (together with the next point – new figure). Furthermore, might I also
suggest considering use different figure for this scenario since it is not very
similar (please find the attached figure as a version, which is editable, to
show the difference, the RS in this figure is not fixed relay and is also
different from mobile relay we have defined in this document so far). Also, for the mobile
relay usage model section, it should make clearer if MS can communicate to any
RSs or MS is required to communicate with mobile vehicle carried RS (especially
for the tunnel one) Best regards, Yong Sun Toshiba Research Europe
