Managing acknowledgment transmissions from multicast group members of a multicast group within a wireless communications network
First Claim
1. A method of sending acknowledgments to multicast announce messages within a wireless communications network, comprising:
- receiving, at an access terminal, an announce message announcing a multicast session, the announced multicast session being a multicast session that the access terminal wishes to monitor; and
sending, from the access terminal, a multicast registration message requesting registration to the announced multicast session for the access terminal and an announce acknowledgment message acknowledging that the announce message has been received, the multicast registration message and announce acknowledgment message being sent to an access network within a single bundled transmission on a reverse link channel.

Abstract
Aspects of managing acknowledgment transmissions from multicast group members of a multicast group within a wireless communications network are disclosed. An access network transmits an announce message announcing a multicast session to a plurality of access terminals. One of the plurality of access terminals (i.e., a first responder) sends a BCMCSFlowRegistration message and an announce acknowledgment (ACK) message to the access network. In an example, the BCMCSFlowRegistration message and announce ACK message are sent within the same access probe on a reverse link access channel. Next, the access network sends, in response to the received BCMCSFlowRegistration message, a suppression message to request access terminals not to send announce acknowledgment messages for the announced multicast session. Alternatively, an application server sends the suppression message in response to the received announce ACK message. In either scenario, the access terminals receiving the suppression message suppress transmission of subsequent announce ACK messages.
