20090080355 | RESPONDING TO AN INTRACTIVE MULTICAST MESSAGE WITHIN A WIRELESS COMMUNICATION SYSTEM - Wireless communication systems and methods of scheduling access terminal responses to an interactive multicast message are provided. A radio access network (RAN) generates an access control message (ACM), the ACM indicating feedback instructions for a plurality of access terminals (ATs) belonging to a given multicast group. The feedback instructions of the ACM designate a temporary manner in which the plurality of access terminals are to respond to an interactive multicast message. The target ATs receive the interactive multicast message as well as the ACM. The target ATs, or multicast group members, respond to the interactive multicast message based on the feedback instructions for the plurality of access terminals indicated by the ACM. | 03-26-2009 |
20090080356 | MANAGING ACKNOWLEDGMENT TRANSMISSIONS FROM MULTICAST GROUP MEMBERS OF A MULTICAST GROUP WITHIN A WIRELESS COMMUNICATIONS NETWORK - 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. | 03-26-2009 |
20090080357 | MULTICAST MESSAGING WITHIN A WIRELESS COMMUNICATION SYSTEM - Methods and systems for sending multicast messages are disclosed. A multicast message is received to be transmitted to a plurality of access terminals at a radio access network (RAN), the received multicast message having a first format. The first format may correspond to a conventional multicast message format. The RAN determines whether the received multicast message requires special handling. If the RAN determines the received multicast message requires special handling, the radio access network converts the received multicast message from the first format into a second format. The RAN transmits the converted multicast message with the second format (e.g., a data over signaling (DOS) message) on a control channel to at least one of the plurality of access terminals. The access terminals receiving the converted multicast message interpret the message as a multicast message. | 03-26-2009 |
20090080358 | TERMINATING A MULTICAST SESSION WITHIN A WIRELESS COMMUNICATIONS NETWORK - A wireless communication system and methods thereof are disclosed. A server (e.g., a push-to-talk (PTT) server) determines a multicast message to be a final multicast message for a multicast session having an indeterminate end time. The server inserts a flag into the multicast message, the inserted flag indicating that the flagged multicast message is a final multicast message for the multicast session. The server sends the flagged multicast message to a communication entity (e.g., a radio access network (RAN), a broadcast serving node (BSN), etc.) supporting the multicast session. The communication entity (e.g., RAN, BSN, etc.) receives the multicast message from the server. The communication entity determines whether the received multicast message includes a flag relating to multicast session termination. The communication entity releases at least one channel associated with the multicast session based on the determining step. | 03-26-2009 |

20090080360 | Reducing an occurrence of false grants for a multicast session within a wireless communications network - Aspects of reducing an occurrence of false grants for a multicast session within a wireless communications network are disclosed. For example, an access network receives an announce message to be transmitted to a plurality of access terminals, the received announce message configured to announce a given multicast session. The access network determines whether sufficient resources are available to support the given multicast session. The access network configures the received announce message to convey whether sufficient resources are available to support the given multicast session based on the determining step, and transmits the configured announce message to the plurality of access terminals. A given access terminal receives the announce message, and determines whether the received announce message indicates whether sufficient resources are available to support the given multicast session. The given access terminal sends an announce acknowledgment (ACK) message that indicates an acceptance or rejection of the given multicast session. | 03-26-2009 |
20090080361 | DE-REGISTERING A MULTICAST GROUP MEMBER FROM A MULTICAST GROUP WITHIN A WIRELESS COMMUNICATIONS NETWORK - Aspects of de-registering a multicast group member from a multicast group within a wireless communications network are disclosed. An access terminal sends a first multicast registration message to an access network, with the first multicast registration message identifying a first set of multicast groups. The access network receives the first multicast registration message and registers the access terminal for each of the first set of multicast groups. The access terminal sends a second multicast registration message, the second multicast registration message omitting at least one multicast group from among the first set of multicast groups, the second multicast registration message being sent to request de-registration, for the access terminal, from at least one multicast group. The access network receives the second multicast registration message and interprets the second multicast registration message as a request to de-register the access terminal from the omitted at least one multicast group. | 03-26-2009 |

A given UE receives the periodically broadcasted message from the AN and determines to perform the given type of transmission. The given UE refrains from measuring the reverse-link channel, as instructed by the AN, based on the data being associated with a communication session of a given type. The given UE transmits the data to the AN. If the data transmission omits the requested measurement results, the AN selects a transmission format for subsequent transmissions of the given UE based on the omission. | 06-09-2011 |
20110134770 | OUTER LOOP POWER CONTROL IN A WIRELESS COMMUNICATION SYSTEM - In an embodiment, an access network receives a message associated with a given user equipment (UE). The received message can be an uplink message received from the given UE itself (e.g., a measurement report, a cell update message), or can be a downlink message for transmission to the given UE (e.g., a call announcement message). The access network determines that the received message is associated with a communication session of a given type (e.g., a delay-sensitive communication session). The access network selects an uplink initial signal-to-interference ratio (SIR) target for the given UE based on the determination.

20110134836 | ANNOUNCING A COMMUNICATION SESSION WITHIN A WIRELESS COMMUNICATIONS SYSTEM - An access network (AN) receives a call announcement message for transmission to an access terminal (AT). The AN initiates, in response to the received call announcement message, a physical-layer synchronization procedure for at least one channel between the AN and the AT, the physical-layer synchronization procedure associated with a transition of the access terminal to a dedicated channel state. The AN performs the initiation by sending a message to the AT. In response to the message, the AT monitors a downlink channel for receipt of the call announcement message. The AN then transmits the call announcement message on the downlink channel to the access terminal, and the AT receives the call announcement message due to the monitoring. The call announcement message is transmitted either (i) before the physical layer synchronization procedure completes or (ii) before a transmission of a reconfiguration complete message indicating completion of dedicated channel state transition. | 06-09-2011 |
20110134888 | PAGING OF A USER EQUIPMENT (UE) WITHIN A WIRELESS COMMUNICATIONS SYSTEM - A user equipment (UE) determine to activate a data session.

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. | 02-20-2014 |
