When using the secondary paging system, can further reduce power.The secondary paging system utilizes Page Indication Channel (PICH).
Mobile radio station is monitored PICH termly, and when occurring indicating certainly, mobile radio station is known the PCH that monitors reality so, because it may only comprise the message that is addressed to this mobile radio station until now.
Several mobile radio stations can be monitored identical paging occasion.Therefore, any paging sign of the paging acknowledgment that receives of mobile radio station check whether with it self marking matched.If coupling, then communicating by letter with this mobile radio station is target.
Receiving or emission is called as in active state or pattern with the mobile radio station of communicating by letter except that beep-page message of base station.
Wish when mobile radio station is in idle pulley, to reduce the power consumption of a plurality of receivers of mobile radio station.
