          [Satoru] Thank to a lot of effort on this in IETF side. As 3GPP requests
          any info on UP protocol to figure out criteria and candidate protocols,
          the LS contents looks appropriated.    
          [Dave] It includes non-WG documents which are not clear when it comes
          to LS contents.
