And when the value of Service _ operations _ Mirror is defined to be 29, it indicates that the mobile station 3 is updated with the group number information, when the value of Service _ operations _ Mirror is defined to be 30, it indicates that the mobile station 3 is updated with the frequency point information in the trunking mode, and when the value of Service _ operations _ Mirror is defined to be 31, it indicates that the mobile station 3 is updated with the frequency point information in the transit or through mode.
The frequency point information and the group number information which need to be updated by the mobile station 3 are transmitted by using the downlink UDT signaling of the control channel, and a complete UDT message consists of a plurality of frames of signaling and respectively comprises 1 UDT signaling head frame, 0 to 3 UDT intermediate frames and 1 UDT end frame.
