REDUCING PAGING RESPONSE TIME IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of reducing paging response time in a wireless communication system for a target mobile station operable using slotted and unslotted modes in multiple paging location areas of the communication system, the method comprising the steps of:
- receiving a paging request message for the target mobile station operating in slotted mode;
setting a paging indicator for the target mobile station;
broadcasting the paging indicator to all paging location areas of the communication system;
operating the target mobile station in an unslotted mode upon recognition of the paging indicator by the target mobile station;
paging the target mobile station in a last known location and failing to establish contact with the mobile station;
re-paging the target mobile station in at least one selected location area of the system; and
operating the target mobile station in slotted mode again upon successful receipt of the page by the target mobile station and processing of a call associated with the paging request message.

Abstract
A method and wireless communication system to reduce paging response time for a target mobile station (MS) operable using slotted and unslotted modes in multiple paging location areas of the system includes a first step 300 of receiving a paging request message for the MS. A next step 302 includes setting a paging indicator for the MS. A next step 304 includes broadcasting the paging indicator to all paging location areas of the system. A next step 306 includes operating the MS in unslotted mode upon recognition of the paging indicator. A next step 308 includes paging the MS in a last known location and failing to establish contact with the MS. A next step 310 includes re-paging the MS in selected location areas of the system based on a probability based search algorithm. A next step 312 includes operating the MS in slotted mode again upon successful call processing.

8. A method of reducing paging response time in a wireless communication system for a target mobile station operable using slotted and unslotted modes in multiple paging location areas of the communication system, the method comprising the steps of:
-
receiving a paging request message for the target mobile station operating in slotted mode; setting a paging indicator for the target mobile station; broadcasting the paging indicator to all paging location areas of the communication system in a time period preceding a next slot cycle of the target mobile station; operating the target mobile station in an unslotted mode upon recognition of the paging indicator by the target mobile station; paging the target mobile station in a last known location and failing to establish contact with the mobile station; re-paging the target mobile station in at least one different selected location area for each subsequent paging frame of the unslotted mode; and operating the target mobile station in slotted mode again upon successful receipt of the page by the target mobile station and processing of a call associated with the paging request message. - View Dependent Claims (9, 10, 11)

12. A system for reducing paging response time for a target mobile station operable using slotted and unslotted modes in multiple paging location areas of a wireless communication system, the system comprising:
-
a mobile switching center (MSC) operable to send a paging request message for the target mobile station that is operating in slotted mode; at least one base station controller (BSC) coupled to the MSC, the at least one BSC operable to set a paging indicator for the target mobile station and broadcast the paging indicator to all paging location areas of the communication system; a target mobile station that operates in an unslotted mode upon recognition of the paging indicator; a portion of a plurality of base transceiver stations serving a last known paging location of the target mobile station operable to receive the paging request message, the base transceiver stations operable to page the target mobile station in a last known location, wherein if the portion of bases transceiver stations fail to establish contact with the target mobile station in the last known paging location, the MSC operates to re-page the target mobile station in at least one selected location area of the communication system; and the target mobile station is operable to switch a slotted mode of operation again upon successful receipt of the page and processing of the call between the MSC and mobile station. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
