ABSTRACT:
A method of reducing paging channel usage in a CDMA communication system. Each mobile switching centre maintains in its visitor location registry information regarding a paging channel or carrier frequency that each mobile station registered is monitoring. Then, when it comes time to send a page to a mobile station, the mobile switching centre looks up the information and appends it to the page which is sent to all basestation transceivers. The basestation transceivers extract the information and identify the paging channel the mobile station to which the page is addressed is monitoring. The transceivers then broadcast the page message over their air interfaces on the identified paging channel.
