Abstract: In an embodiment, an access terminal includes at least first, second and third functional layers, whereby the first functional layer (e.g., a MAC layer) attempts to a data packet on behalf of the third functional layer (e.g., an application-layer) to an application server via a serving network. If the first functional layer receives an ACK that the serving network has received the data packet, the third functional layer is notified of the ACK. If the first functional layer determines the attempt to transmit the data packet to the serving network has failed, the third functional layer is notified of the transmission failure. In another embodiment, during set-up of a traffic channel (TCH) for a communication session, the access terminal transmits a message to the application server over a signaling port that includes both application-layer and transport-layer connection information to facilitate set-up of a data port for the communication session.

Abstract: In an embodiment, objects are downloaded to an access terminal (AT) based on which window(s) are prominently displayed on the AT. In another embodiment, objects are downloaded to the AT based on a set of user-specified object download priorities. In another embodiment, a portion of a streaming data session to the AT is de-prioritized in response to a transition of a display of the AT from a first set of windows associated with the streaming data session to a second set of windows associated with a different session. For example, the de-prioritization can result in the portion (e.g., a video-portion of a audio and video conference) being omitted or reduced. In another embodiment, in response to the AT entering a limited environment, objects being downloaded to the AT can be dynamically altered to conform with the AT's limited environment.

Abstract: In an embodiment, an application server determines a priority associated with a given multicast message for transmission to at least one access terminal, configures the given multicast message to indicate the priority of the given multicast message and forwards the configured multicast message to an access network for transmission to the at least one access terminal a number of times based at least in part on the indicated priority. Alternatively, the application server can indicate, in the configured multicast message, the number of times to transmit the given multicast message. The priority, or number of times to transmit the given multicast message, can be conveyed to the access network by a flag inserted into the configured multicast message by the application server. The access network determines the number of times to transmit the given multicast message to the at least one access terminal based on the flag.

Abstract: At least one embodiment of the invention is directed to communicating in a wireless communications system, including monitoring a communication session on a first network, ignoring pages from a second network during the communication session, the first and second network configured for operation on different physical layers, and upon termination of the communication session over the first network, selectively sending a query to an application server to request information related to failed attempts by the application server to contact the access terminal on the second network during the communication session.

Abstract: In an embodiment, an access network monitors traffic, associated with a radio bearer of a given type (e.g., a radio bearer expected to be associated with delay-sensitive and/or high-priority communication sessions), between a user equipment (UE) in a dedicated-channel state (e.g., CELL_DCH state) and an application server that is arbitrating a communication session between the UE and at least one other UE. Based on the monitored traffic, the access network selectively transitions the UE away from the dedicated-channel state. For example, if traffic on the radio bearer of the given type is detected before expiration of a timer, the UE can be permitted to remaining in the dedicated-channel state. Alternatively, if no traffic on the radio bearer of the given type is detected before expiration of the timer, the UE can be transitioned away from the dedicated-channel state (e.g., into CELL_FACH, CELL_PCH or URA_PCH state).

Abstract: Embodiments are directed selectively mixing media at an application server arbitrating a group communication session for a communication group. In an embodiment, the application server receives media, from one or more session participants of the group communication session, for transmission to the communication group. The application server determines a number of session participants that are providing the received media. The application server determines whether to bypass the received media from entry into a de-jitter buffer based at least in part on the determined number, wherein the de-jitter buffer is configured to queue media from session participants for mixing by the application server during the group communication session. For example, the application server can determine to bypass the received media from entry into the de-jitter buffer if the number is below a threshold number. The application server transmits the received media to the communication group.

Abstract: An embodiment includes based on an evaluation of multicast communication session identifier(s) of a given multicast communication session, selecting between (i) querying a remote server for a multicast flow identifier, and (ii) applying a pre-defined mapping protocol to the multicast communication session identifier(s) to generate the multicast flow identifier. Another embodiment includes, based on an evaluation of a multicast flow identifier of a given multicast communication session selecting between (i) querying a remote server to obtain a set of session parameters for the given multicast communication session, and (ii) loading a set of pre-defined session parameters for the given multicast communication session. Another embodiment includes applying a pre-defined mapping protocol to (i) a given portion of a first multicast communication session identifier, (ii) a given portion of a second multicast identifier and (iii) a pre-defined prefix in order to generate a multicast flow identifier.

Abstract: Embodiments include managing a reverse link transmission power level setpoint during periods of data inactivity on a reverse link traffic channel in a wireless communications system. At an access terminal, upon detecting reverse link data inactivity above a time threshold, a message is generated and transmitted on the reverse link traffic channel at a power level sufficient for the access network to measure transmission statistics to determine whether to adjust the current transmission power level setpoint of the access terminal. Alternatively, the access terminal notifies the access network of an upcoming reverse link data inactivity period, and then lowers its transmission power level setpoint to reduce power consumption during the reverse link data inactivity period. Then, upon detection of a potential reverse link data transmission, the access terminal may then send one or more messages to prompt the access network to modify the access terminal's transmission power level setpoint.

Abstract: An embodiment is directed to an access network that configures set of paging indicator (PI) bits within a quick paging channel (QPCH) cycle to page a group of access terminals. An access terminal within the group receives the QPCH cycle, and evaluates the PI bits to determine whether a unicast page and/or group page is present. Another embodiment is directed to selecting less than all timeslots in one or more control channel cycles of a downlink control channel, and configuring a page message to convey the selected timeslots to an access terminal. The access terminal receives the configured page message and decodes information only within the selected timeslots. Another embodiment is directed to generating a transport-layer message for transmission to at least one access terminal, and configuring the transport-layer message by modifying an application-layer portion of the transport-layer message. An access terminal receives the message and extracts the application-layer portion.

Abstract: A network communication entity (e.g., an access terminal, access network and/or application server) obtains a location associated with a given access terminal that is attempting to participate in a given communication service, obtains a priority level of the given access terminal, determines a given level of service restriction for the given access terminal's participation in the given communication service based on the obtained location and the obtained priority level and restricts the given access terminal's participation in the given communication service based on the given level of service restriction. In an example, the priority levels can be established such that low-priority access terminals obtain a first level of service restriction within a defined location region, and a second level of service restriction outside of the defined location region, whereas high-priority access terminals obtain the first level of service restriction both inside and outside of the defined location region.

Abstract: In an embodiment, a network communication entity obtains a location associated with an access terminal that is attempting to participate in a communication service, determines whether the obtained location satisfies a relationship with a defined location region, the defined location region establishing a first level of service restriction for the communication service within the defined location region and establishing at least a second level of service restriction for the communication service outside of the defined location region, and restricts the access terminal in accordance with the first or second level of service restriction for the communication service based on the determination. The network communication entity may correspond to the access terminal, an access network or an application server. If the access terminal detects a current, imminent or future service restriction, the given access terminal can initiate handoff to another service mechanism and/or inform the user of the service restriction.

Abstract: Embodiments are directed to scheduling location update reports of access terminals to an access network within a wireless communications system. The access network acquires a defined location region within a wireless communications system, and determines a location of a given access terminal within the wireless communications system. The access network selects one of a plurality of location update rules for the given access terminal based on a relationship between the defined location region and the determined location, each of the plurality of location update rules specifying different conditions for prompting location update reports from the given access terminal to the access network. The access network informs the given access terminal of the selected location update rule, and the given access terminal sends one or more location update reports to the access network in accordance with the selected location update rule.

Abstract: An access network receives a request from an access terminal for communication session support resources associated with a communication session, determines whether sufficient communication session support resources are available for allocating to the access terminal and selects communication session support resources from another access terminal for de-allocation, the selected at least one communication session support resource associated with a communication session having a lower priority than the communication session. The access network sends instructions to the at least one other access terminal to facilitate de-allocation of the selected communication session support resource, and allocates communication session support resources to the access terminal for supporting the communication session after the selected communication session support resource is de-allocated from the other access terminal.

Abstract: In an embodiment, an application server determines a priority associated with a given multicast message for transmission to at least one access terminal, configures the given multicast message to indicate the priority of the given multicast message and forwards the configured multicast message to an access network for transmission to the at least one access terminal a number of times based at least in part on the indicated priority. Alternatively, the application server can indicate, in the configured multicast message, the number of times to transmit the given multicast message. The priority, or number of times to transmit the given multicast message, can be conveyed to the access network by a flag inserted into the configured multicast message by the application server. The access network determines the number of times to transmit the given multicast message to the at least one access terminal based on the flag.

An access terminal can include logic configured to determine an optimal paging cycle and logic configured to set the paging cycle based on the optimal paging cycle, where the paging cycle varies based on at least one optimizing metric.

Abstract: Embodiments are directed to determining whether to permit a server-arbitrated communication session at a wireless communications device within a wireless communications system. The wireless communications device receives a request to participate in the server-arbitrated communication session. The wireless communications device obtains information related to a current location of the wireless communications device. The wireless communications device determines whether the obtained information satisfies one or more conditions of restriction and/or permission for participation of the wireless communication device in server-arbitrated communication session. The wireless communications device selectively restricts itself from participating in the server-arbitrated communication session based on this determination.

Abstract: Systems and methods for bundling signals in a wireless communication system are disclosed. A connection request and a reservation for QoS resources can be bundled into an access message at an access terminal. The access message with the bundled communication signals can then be transmitted to an access network. An application layer (e.g., a DataOverSignaling (DOS)) message can also be bundled with the connection request and the reservation into the access message.

Abstract: The invention concerns routing, scheduling, and power control methods for single and multi-hop wireless networks. A multi-hop network is one in which source and destination nodes may communicate directly or through relay nodes. Nodes in single hop networks communicate without use of relay nodes. Embodiments of the invention may produce an optimal schedule to provide for the best-case goal for a given parameter. In a preferred embodiment, total power is the parameter and total power is minimized for the network. In another preferred embodiment, data throughput is the parameter, and throughput is maximized for the network.

Abstract: 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.
