Abstract
Abstract An acknowledge-back selective call system (100) transmits a first acknowledge-back page (300) that includes a first message data (306) and address information (302) that matches a first predetermined address (140) at an acknowledge-back selective call transceiver (130) and a second acknowledge-back page (300) that includes a second message data (306) and address information (302) that matches a second predetermined address (142) at the acknowledge-back selective call transceiver (130). The acknowledge-back selective call transceiver (130) receives the second acknowledge-back page (300), and, in response thereto, transmits an acknowledge-back confirmation response (500), the acknowledge-back confirmation response (500) including a message reception status information (502) indicating a message reception status for the first acknowledge-back page (300) and a message reception status information (504) indicating a message reception status for the second acknowledge-back page (300).

A method in an acknowledge-back wireless selective call system capable of transmitting multi-recipient acknowledge-back pages destined for reception by a plurality of selective call transceivers and single-recipient acknowledge-back pages destined for reception by a one selective call transceiver of the plurality of selective call transceivers, the method comprising the steps of: (a) wirelessly transmitting a multi-recipient acknowledge-back page; (b) receiving the multi-recipient acknowledge-back page by a plurality of selective call transceivers; (c) at each of the plurality of selective call transceivers, in response to decoding of a page as a multi-recipient page, delaying the transmission of an acknowledgment signal responsive to the multi-recipient acknowledge-back page until after a single-recipient acknowledge-back page is separately, individually received by each of the plurality of selective call transceivers; (d) subsequent to the step of wirelessly transmitting the multi-recipient acknowledge-back page, wirelessly transmitting a single-recipient acknowledge-back page destined for reception by a one selective call transceiver of the plurality of selective call transceivers; (e) receiving the single-recipient acknowledge-back page by the one selective call transceiver; and (f) at the one selective call transceiver, in response to decoding of a page as a single-recipient acknowledge-back page, wirelessly transmitting a single acknowledgment signal including information indicating a message reception status for the multi-recipient acknowledge-back page received at step (b), and information indicating a message reception status for the single-recipient acknowledge-back page received at step (e).
