    摘要: A system and method for detecting discontinuous transmission (DTX) frames. The inventive method includes the steps of receiving data transmitted in a plurality of frames; classifying each of the frames; analyzing the classification of a number of successive frames of the received data and providing a metric with respect thereto; and determining, in response to the metric, if a frame is a discontinuous frame. In the illustrative embodiment, the step of classifying includes the step of error checking the frames using a cyclic redundancy check (CRC) error checking protocol. The received frames are classified as good frames (G), erasure frames (E), or discontinuous frames (D). A numerical value is assigned to each of the frames based on the classification thereof. Next, the frames are filtered to provide an output Yn=Yn−1+Xn where ‘n’ is a frame number, Yn is the filter output for a given frame n, Yn−1 is the filter output for a previous frame, and Xn is a stream of input frames. A threshold is set for the output Yn to facilitate the detection of discontinuous frames. That is, a detection of a discontinuous transmission frame is indicated when a frame is classified as an ‘erasure’ and the filter output exceeds the threshold. On the detection of a discontinuous frame, the classification of the frame is changed from ‘erasure’ to ‘discontinuous’. By reclassifying improperly classified erasure frames, the mobile receiver is inhibited from requesting retransmission of the frames or a change in the transmit power level. Consequently, network throughput and capacity are optimized and system power is conserved.

    摘要: The present invention provides a method and apparatus for maximizing throughput of a data call in a wireless communication system in which data is transmitted from a wireless station, such as a mobile station, on multiple assigned channels in accordance with a known transmission standard, such as IS-95B. The multiple assigned channels include a fundamental channel and at least one supplemental channel. Data is formatted into variable rate data frames and transmitted on the fundamental channel and the supplemental channel. A wireless receiver, such as a base station, receives the multiple assigned channels. The wireless receiver demodulates and decodes data frames associated with each of the multiple assigned channels. The wireless receiver determines a likely initial data rate for each demodulated and decode data frame. The wireless receiver correlates all of the likely data rates, by comparison to one another and to a relevant transmission protocol standard, to determine a maximum likelihood combination of data rates. The maximum likelihood combination of data rates includes a maximum likelihood data rate corresponding to each likely data rate. Decoded data frames are invalidated and erased when the likely data frame rates do not match corresponding maximum likelihood data rates.

    摘要: A deployment and distribution model improves content delivery with a business incentive for placement of kiosks with one or more wireless access points in public locations so that portable media players (PMPs) can receive media content (e.g., audio, video, text, haptic content, etc.). In addition, coordination between subscribing users of PMPs, vendors who provide kiosks, and a network central controller of a content distribution system allow for prepositioning of video content at the kiosks through economically desirable low data rate communication links from the network (e.g., dial-up modem, DSL, etc.); coordinated queuing of downloads (e.g., partial downloads) between kiosk to PMP, peer-to-peer (P2P) downloading between PMPs, and uploads from PMP to kiosk; billing/crediting to correspond with such participation in the distribution; and changing priority/selection of prepositioning of content at kiosks to reflect a clientele profile.

    摘要: Methods, apparatus, systems and computer program products are provided for an improved media content rating system. The rating system herein disclosed is highly-granular in nature, in that, the rating system allows for ratings to be based on the number of times that portions, segments, clips of the media file are played or otherwise executed, as opposed to basing the media content rating solely on the number of times that the media file is played. In this regard, the aspects herein described may further provide for ratings of the portions, segments, clips of the media content as opposed to limiting the rating to a rating for the overall media content file.

    摘要: A method and apparatus provide for scheduling reverse link transmission for a mobile station in a timely manner. A base station (101) may transmit on a forward link high rate channel and a forward link low rate channel to a mobile station during a common time slot. The high rate and low rate channels may be respectively the F-PDCH and the F-PDCCH. The base station may transmit a reverse link transmission scheduling information on the low rate channel. The mobile station may schedule transmission on the reverse link channel, such as R-SCH, based on the data received on the low rate channel. Since the low rate channel has only scheduling data (16 bits) and the high rate channel may have no data (null data) at all, the base station may decide to transmit the reverse link scheduling information to the mobile station very quickly on the forward link.
