There was no need to introduce PSCN but I guess the designers wanted to clearly separate signalling that's specific to NACC. PSI is sent on PBCCH and PACCH. If an MS requires updated PSI it would be sent to it on PACCH while GPRS Transfer Mode. For the purpose of debugging, it is difficult to ascertain if the PSI transmission was triggered because of an update or because of the requirements of NACC. I expected sensible implementations would always use PSCD if the transmission has been triggered for NACC. Good observation.
