Method for effective fast re-paging in a wireless communication network
First Claim
1. A method comprising:
- determining, by a base station, a first group of sectors where a communication device is most likely to be located according to one of a presence of an overload condition indicator and membership of a cell within a higher priority paging group;
determining, by the base station, a second group of sectors where the communication device is most likely to be located when the communication device is not in the first group of sectors according to one of a presence of an overload condition indicator and membership of a cell within a higher priority paging group;
sending, by the base station, a first paging message in a first zone to the communication device wherein the first paging message is sent at the beginning of a paging interval, wherein the first zone comprises the first group of sectors;
receiving a response to the first paging message when the communication device is in the first zone; and
sending, by the base station, a second paging message in a second zone when the response to the first paging message is not received, wherein the second zone comprises the second group of sectors, wherein the second paging message is sent at a first offset from the sending of the first paging message, and wherein the first offset occurs less than one paging interval after the sending of the first paging message,wherein the first paging message is sent over a first distance, wherein the second paging message is sent over a second distance, and wherein the first distance is different from the second distance.

Abstract
A method for paging a mobile station where the mobile station (208-212) may be in a dormant state is described. The method begins by sending a first paging message (302) in a first zone (214) of a given area to a selected mobile station wherein the first paging message is sent at the beginning of a paging interval (300). A base station (202-206) then receives a response to the paging message when the mobile station is in the first zone. When the response to the first paging message is not received, a second paging message (306) is sent in a second zone (216) of the given area. The second paging message is sent at a first offset (308) from the sending of the first paging message wherein this first offset occurs less than one paging interval after the sending of the first page message.
