Expanded signalling capability for network element, user equipment and system.

A plurality of mobile station identifier assigned to a mobile station an identifier for a plurality of possible signalling channel structure parameter or both of them to each. When the received signalling channels the mobile station in the received signalling channels is assigned to it searches for all identifiers. When the mobile station to find that is matched with identifier the mobile station such as to check map table by rrc signalling in mobile station and network is connected between the building time so as to achieve the same so as to determine the mark representing the meaning of. The transmission of the invention is used in the signalling channel structure parameter or both of them can be implicitly or explicitly by the identifier for indicating. Mobile station user equipment is used in the normal way to monitor signal channel. It instead of looking for only one identifier the mobile station it belongs to the monitor several identifiers.
