  • Patent number: 7697447
    Abstract: A packet data communication system that includes a mobile station having a jitter buffer and a wireless infrastructure having a base site serving the mobile station controls a size or dept of the jitter buffer. The size or depth is controlled based on a number of retransmissions of erroneously received data employed by the system, a radio frequency load of the base site, and a round trip time period for acknowledgments and corresponding retransmissions. The jitter buffer size may be further controlled by use of a supplemental channel to expedite the transmission of data and thereby fill up the jitter buffer more quickly and by reduction of a waiting period for retransmission of the acknowledgments, thereby reducing the round trip time period.

  • Patent number: 7689208
    Abstract: A communication system, upon receiving an instruction to transfer deferrable data, determines whether an air interface is congested and, when the air interface is congested, defers a transfer of the deferrable data or transfers the deferrable, lower priority data as higher priority data. When, during a transfer of deferrable data, the system determines that the air interface is congested, the system may terminate the call and save a state of a partially completed deferred data transfer. Subsequent to the termination of the call, the system establishes another data connection over the air interface and transfers any remaining, not yet transferred deferrable data. In order to discourage subscribers from transferring higher priority data as lower priority data, the system may further restrict a transfer of lower priority data to designated time periods while allowing a transfer of higher priority data during the designated time periods and other time periods.

  • Patent number: 7680487
    Abstract: Upon detecting (201) a communication need for a group of communication recipients that entails attempting to make at least one transmission to each of the communication recipients in the group (wherein at least one of the communication recipients has both a scheduled personal communication opportunity and a scheduled group communication opportunity), one automatically uses (202) whichever of the scheduled communication opportunities occurs first to make the at least one transmission to the communication recipient(s) for which this option applies. In one approach this response is further informed and influenced by one or more other factors, such as but not limited to system loading (203), group size and/or known whereabouts (204), and/or whether a recent transmission response was received (205).

  • Publication number: 20100058390
    Abstract: A content item recommendation system comprises a recommender (203) which generates a set of recommendations for content items available through a first content item distribution system. A coordination processor (205) determines an availability characteristic for a set of content items available through a second content item distribution system of a set of content item distribution systems. The availability characteristic may indicate which content items are available to a user via the second content item distribution system. The modification processor (207) then modifies a recommendation characteristic for the set of recommendations in response to the availability characteristic for the set of content items. The approach may enable or facilitate coordination between different content item distribution systems while still allowing separate and independent operation of the content item distribution systems.

  • Publication number: 20090274224
    Abstract: In an Orthogonal Frequency Division Multiplexing communication system wherein a frequency bandwidth is divided into multiple sub-bands, a method and a scheduler is provided for configuring channel quality feedback for a point-to-multipoint communication session involving multiple users equipment (UEs). The scheduler receives multiple channel quality measurements from the multiple UEs and, based on the multiple channel quality measurements, determines whether to implement a frequency selective channel quality feedback scheme or a non-frequency selective channel quality feedback scheme for the point-to-multipoint communication session. The scheduler then implements the determined channel quality feedback scheme. In another embodiment of the invention, the scheduler may determine whether to implement a frequency selective or non-frequency selective channel quality feedback scheme based on a number of UEs serviced by the scheduler.

  • Patent number: 7609639
    Abstract: Logic circuitry (409) constantly monitors a transmitter (410) to determine if the transmitter (410) is idle. Logic circuitry (409) suppresses all NAKs until data and other channel information is not being transmitted by the transmitter (410) and RF resources are not scarce. Additionally, logic circuitry (409) suppresses all NAKs until a predetermined number of NAKs has been buffered by the logic circuitry (409). More particularly, logic circuitry (409) determines when a number of NAKs will sufficiently fill an over-the-air frame. Once the predetermined number of NAKs has been collected, the logic circuitry (409) will generate the appropriate NAKs.
