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.

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.

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).

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.

Abstract: A method and an apparatus that includes establishing a link (106) between a first node (102) and a second node (104) in a wireless communication network (100). The method continues by setting a discontinuous receive (DRX) transmission mode cycle for the link wherein the DRX cycle includes an on duration (202) followed by an off cycle (204). The duration of the on duration on a downlink is adjusted (610) based on a function of the availability of a channel quality indicator (CQI) channel used on the link.

Abstract: A number of uplink transmissions from multiple remote devices is received. The remote devices correspond to a single network node, and each of the uplink transmissions corresponds to a request for content. A subset of remote devices whose uplink transmissions correspond to requests for common content is identified and a Quality of Service (QoS) level corresponding to the number of remote devices in the identified subset is determined. The common content is transmitted to the single network node at the determined QoS level.

A next step (402) includes receiving an indication of availability of the presence entity. A next step (404) includes controlling communication access with the presence entity based on the at least one privacy rule, wherein communication access between the presence entity and the caller is controlled by the priority for that caller and the availability indication of the presence entity.

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.

Abstract: A method includes transmitting a paging request message to a plurality of asynchronous base stations (102a-g) where a paging message is sent within its respective cell at any time within a given paging interval (202). The method continues by receiving notification that paged mobile station (106) has responded to a paging message. The page cancelling message indicates to the base stations do not need to send the paging message within their respective cells during the current paging interval and that the paging process is cancelled.

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.

Abstract: Various embodiments are described for potentially reducing the impact of routing area updates on wireless system capacity. Logic flow diagram 10, in FIG. 1, depicts such functionality. In some embodiments, it is determined (12) whether a remote unit is within an edge portion of a routing area, while in other embodiments it is determined (12) whether the remote unit is within an end portion of a routing area update interval. It is also determined (14) whether one or more conditions are present for the remote unit to perform a resource-efficient routing update. A routing area update is then performed (16) when one or more of the conditions are present and when, depending on the embodiment, either the remote unit is determined to be within the edge portion of the routing area or the remote unit is determined to be within the end portion of the routing area update interval.

Abstract: A communication system provides network-based battery power management that may be transparent to a user of a mobile station (MS). When one or more elements of a network of the communication system determines that the MS is operating at a low power supply charge level and/or has experienced a significant change in a charging level of the power supply, the one or more network elements may arrange for postponement of delivery of a delay-tolerant service to the MS or for adjustment of one or more of a characteristic of a service provided to the MS and a parameter of a radio communication with the MS, including restoration of full services to an MS whose power supply charge level has been restored.

Abstract: A communication device converts a bit stream to multiple symbols and provides encryption at a physical layer by shifting a phase of each symbol of the multiple symbols to produce multiple encrypted symbols. Each encrypted symbol of the multiple encrypted symbols is modulated with an orthogonal subcarrier to produce at least one modulated subcarrier and the at least one modulated subcarrier is then transmitted via a wireless link. On a receive side, a receiving communication device receives the transmitted, encrypted symbols and provides decryption at a physical layer by shifting a phase of each encrypted symbol in correspondence with the phase used to encrypt the symbol at the transmit side.
