First Claim
1. A method for managing paging resources associated with a push-to-talk communication session in a wireless communication system comprising:
- receiving an invitation to a Push-to-Talk (PTT) communication session that is intended for a mobile station;
requesting a page of the mobile station;
starting a first timer and a second timer, wherein the second timer is longer than the first timer;
re-starting the first timer and re-requesting a page of the mobile station each time the first timer expires prior to both a receipt of a response to the request and a predetermined number of expirations of the first timer; and

Abstract
A communication system provides for an expedited response to an invitation to a Push-to-Talk (PTT) communication session from a terminating side of the communication system when a target mobile station (MS) is not currently available to participate in a PTT communication session by responding to a PTT session invitation prior to an expiration of a second, Paging timer and after a predetermined number of expirations of a first, Tbsreq9 timer or after a predetermined number of unsuccessful requests to page the target MS. In another embodiment of the invention, the communication system may further consider the contents of a downlink buffer of a terminating side Packet Control Function in determining whether and when to respond to an invitation to a PTT communication session, utilizing a third, TpagingBackoff timer in determining when to request a page of a non-responsive target MS.
