问题如题，请帮忙详细解释一下。Packet Cell Change Order
This message is sent on the PCCCH or PACCH by the network to the mobile station to command the mobile station to leave the current cell and change to a new cell. For a (3G) multi-RAT mobile station the new cell may be a 3G Cell. For a (E-UTRAN) multi-RAT mobile station the new cell may be an E-UTRAN cell.
CCO：3G or 4G to 2G
Cell Change Order from UTRAN
Cell Change Order from EUTRAN
