Method And Apparatus For Modifying Playback Timing Of Talkspurts Within A Sentence Without Affecting Intelligibility
US Patent:
2008026, Oct 30, 2008
Filed:
Apr 24, 2007
Appl. No.:
11/739548
Inventors:
Rohit Kapoor - San Diego CA, US
Serafin Diaz Spindola - San Diego CA, US
Serafin Diaz Spindola - San Diego CA, US
International Classification:
H04J 3/06
US Classification:
370516
Abstract:
Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switched communications. The de-jitter buffer methods and apparatus presented modify the playback of packets dependent upon whether silence periods are detected inter-sentence or intra-sentence to optimize voice quality in a communication system. In one example, a de-jitter buffer determines the length of at least one silence period associated with a plurality of received packets and determines a time to transmit a portion of the packets based on the determined length of the silence period. In another example, a silence characterizer unit performs this function.

International Classification:
H04W 28/02, H04W 72/10, H04W 72/04
US Classification:
370252, 370329
Abstract:
A base station (e.g., a Node B in a Multi-Point HSDPA network) calculates an amount of data to request from a network node (e.g., a radio network controller or RNC). As a part of the algorithm utilized, a length of a queue at the Node B for buffering the flow may be dynamically adjusted in an effort to optimize the trade-off between buffer underrun and skew. Further, a network node (e.g., the RNC) responds to Node B flow control requests. Here, the RNC may determine the amount of data to send to the Node B in response to the flow control message from the Node B, and may send the data to the Node B. In various aspects of the present disclosure involving a Multi-Point HSDPA system, the flow control algorithm at the RNC coordinates packet flow to the primary serving cell and the secondary serving cell for the UE.

US Classification:
370331, 370328, 370329
Abstract:
A method and apparatus for wireless communication may provide for mobility in a Multi-Point HSDPA network capable of downlink aggregation. Some aspects of the disclosure provide modified mobility events utilized for altering the Active Set for a UE. Here, the addition of a cell to the Active Set can coincide with making that cell a secondary serving cell. Further, the deletion of a secondary serving cell from the Active Set can coincide with switching off the Multi-Point HSDPA mode. Still further, a modified mobility event for an HSDPA serving cell change can be utilized to swap a primary serving cell and a secondary serving cell.

Abstract:
Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switch communications. The de-jitter buffer methods and apparatus presented avoid playback of underflows while balancing end-to-end delay. In one example, the de-jitter buffer is recalculated at the beginning of each talkspurt. In another example, talkspurt packets are compressed upon receipt of all remaining packets.
