20090080364 | SUPPORTING A MULTICAST SESSION WITHIN A WIRELESS COMMUNICATIONS NETWORK - Methods of supporting a multicast session within a wireless communications network are provided. An access terminal adjusts a monitoring rate of a downlink control channel either (i) after transmitting a multicast registration message in a sector that is not supporting a given multicast session or (ii) after receiving an announce message announcing the given multicast session. An access network anticipates the monitoring rate adjustment, and sends a message advertising the given multicast session (e.g., a broadcast overhead message (BOM)) based on the adjusted monitoring rate. Further, the announce message sent by the access network can be sent on the downlink control channel, and can be sent based on expected paging cycles, or monitoring rates, of the downlink control channel at one or more access terminals within the network prior to the monitoring rate adjustment. | 03-26-2009 |
20090080365 | GENERATING MULTICAST FLOW IDENTIFIERS - Methods of generating multicast flow identifiers are provided. In an example, a multicast flow identifier (e.g., a broadcast multicast service (BCMCS) flow identifier (ID)) is generated, with the multicast flow identifier including a portion of a multicast Internet Protocol (IP) address and a portion of a port designation number, the multicast IP address and port designation number collectively designating a given multicast group. | 03-26-2009 |
20090080396 | SELECTIVE REVIEW OF BUNDLED MESSAGES FROM A WIRELESS COMMUNICATION DEVICE - A system, method, and computer device that allow a wireless communication device to selectively bundle messages in an access channel communication packet being sent to another computer device on the wireless communication network, such as a base station are disclosed. The bundled messages are typically sent in response to a request sent to the wireless communication device for response to a specific event, such as the setup of a group communication call. The receiving computer device determines if the access channel communication packet contains data indicating one or more bundled messages are therewithin such that resources only then will expended to review the bundled messages to check for the availability of the requested resources. | 03-26-2009 |
20110021202 | QUALITY OF SERVICE (QoS) RESOURCES WITHIN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, an access terminal sends a request for a level of Quality of Service (QoS) resources to an access network, the QoS resource request associated with a call attempt by the access terminal. The access terminal proceeds with call set-up for the call attempt irrespective of whether the access network grants the QoS resource request. Alternatively, the access terminal waits for an extended period of time before the call attempt is permitted to fail. In a further example, in the event of call failure, the access terminal can refrain from informing a user thereof of the call failure. In another embodiment, the access network can respond to the QoS resource request with an allocation of a lower level QoS resources than requested if the requested QoS resources are not available. The access terminal can likewise be permitted to participate in the call with the lower level QoS resources. | 01-27-2011 |
20110182272 | APPLICATION-LAYER HANDOFF OF AN ACCESS TERMINAL FROM A FIRST SYSTEM OF AN ACCESS NETWORK TO A SECOND SYSTEM OF THE ACCESS NETWORK DURING A COMMUNICATION SESSION WITHIN A WIRELESS COMMUNICATIONS SYSTEM - Embodiments are directed to an application-layer handoff of an access terminal from a first system of an access network to a second system of the access network during a communication session within a wireless communications system. In an embodiment, the access terminal sets up a communication session on the first system. A multimedia client measures application-layer performance parameters for the communication session supported by the first system, and determines whether to handoff the communication session to a second system based at least in part on the application-layer performance parameters. If the multimedia client determines to handoff the communication session to the second system, the multimedia client initiates the handoff and the communication session is transitioned to the second system. | 07-28-2011 |
20120127973 | SYSTEM AND METHOD OF SENDING ACKNOWLEDGMENTS THROUGH CONTROL CHANNELS TO PREVENT UNNECESSARY RETRANSMISSION IN A LIMITED BANDWIDTH WIRELESS COMMUNICATION NETWORK - Techniques for increasing throughput during a file sharing operation including a mobile device are provided. Throughput can be increased by reducing the number of times packets are retransmitted due to ACK signals being delayed due to the lossy nature of over-the-air transmissions. | 05-24-2012 |
20140078898 | HANDING OFF BETWEEN NETWORKS WITH DIFFERENT RADIO ACCESS TECHNOLOGIES DURING A COMMUNICATION SESSION THAT IS ALLOCATED QUALITY OF SERVICE - In an embodiment, a UE performs an IRAT handoff from a source network with a first RAT to a target network with a second RAT, and obtains a channel from the target network. The UE reports a level of QoS on the channel to a server via the target network. The server issues instructions to the UE and/or the target network for modifying the level of QoS in response to the report based on if the level of QoS is insufficient to support a particular type of communication session. In another embodiment, in conjunction with an IRAT handoff, the source network sends a handoff preparation message to the target network to facilitate the target network to initiate setup of a set of channels with a non-IMS application-specific QoS configuration for the UE on the target network in conjunction with the handoff. | 03-20-2014 |
20140119267 | APPLICATION-LAYER HANDOFF OF AN ACCESS TERMINAL FROM A FIRST SYSTEM OF AN ACCESS NETWORK TO A SECOND SYSTEM OF THE ACCESS NETWORK DURING A COMMUNICATION SESSION WITHIN A WIRELESS COMMUNICATIONS SYSTEM - The disclosure uses a low-cost local wireless network to expand coverage of a multicast service. A user device determines whether a signal strength for a detected wireless multicast service is greater than a threshold, determines whether a low cost local wireless network is available, and communicates with an application server over the low cost local wireless network based on the signal strength being not greater than the threshold and the low cost local wireless network being available. A server receives a request from a user device to send multicast communications to the user device over the low cost local wireless network serving the user device, wherein the user device sends the request based on a signal strength of a detected wireless multicast network being less than a threshold and the low cost local wireless network being available, and communicates with the use device over the low cost local wireless network. | 05-01-2014 |
20140192698 | SELECTIVELY ADJUSTING A RATE OR DELIVERY FORMAT OF MEDIA BEING DELIVERED TO ONE OR MORE MULTICAST/BROADCAST SINGLE FREQUENCY NETWORKS FOR TRANSMISSION - In an embodiment, a first MBSFN area is configured to support a higher data rate than a lower data rate portion of a second MBSFN area, and an application server executes a common data rate mode by delivering a data stream for a group session to the first and second MBSFN areas via IP multicast at a common data rate that is regulated by quality feedback. In a further embodiment, the application server exits the common data rate mode and delivers the data stream to the first MBSFN area via IP multicast at an MBSFN-specific data rate that is higher than the common data rate, while delivering the data stream to the lower data rate portion of the second MBSFN area via IP unicast. In another further embodiment, the application server resumes the common data rate mode. | 07-10-2014 |
20140219083 | DYNAMIC QUALITY OF SERVICE (QOS) FOR SERVICES OVER CELLULAR - The disclosure is related to dynamically applying quality of service (QoS) to a call. An aspect determines a packet transmission state of a subscriber on the call, determines whether or not the QoS is allocated to the subscriber, and allocates the QoS to the subscriber based on the QoS not being allocated to the subscriber and the packet transmission state indicating that the subscriber is sending packets. | 08-07-2014 |
20140219167 | QUALITY OF SERVICE FOR WEB CLIENT BASED SESSIONS - The disclosure generally relates to network-initiated and client-initiated mechanisms to enable quality of service (QoS) for web-based client applications that may high efficiency, high performance, or otherwise guaranteed service levels. For example, to enable QoS for calls or other sessions associated a web-based application, one or more signaling messages may be exchanged between a server and a first user equipment (UE) to establish a call between the first UE and a second UE and to establish a peer connection between the server and at least the first UE. As such, QoS may be activated for at least the peer connection between the first UE and the server, wherein the server may route data associated with the web-based application between the first UE and the second UE over the established peer connection to implement the activated QoS. | 08-07-2014 |
20140221023 | SERVER-INITIATED PAGING CYCLES - In an embodiment, a server registers a client application installed on a user equipment (UE), and evaluates one or more paging cycle criteria for the registered client application. The server determines to establish a target paging cycle used for downlink paging of the UE by a network component (e.g., an access network component or a core network component) of a serving network based on the evaluation, and the server transmits, to the network component, a request for the network component to transition the given UE to the target paging cycle based on the determination. The network component receives the request and assigns the target paging cycle to the UE as requested. | 08-07-2014 |
20140369327 | PAGING ACCESS TERMINALS IN A WIRELESS COMMUNICATIONS SYSTEM - 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. | 12-18-2014 |
