Packet System Information (PSI)
these messages are sent asap to the MS after a cell reselection during packet transfer mode. They allow the MS to resume the transfer, this is the reason why they are provided to the MS earlier than their usual occurence in the PACCH.

It is a special feature, of cours, which allows a shorter reselection outage.
