Patent number: 7609716Abstract: In a transmitter, data segments are transmitted in accordance with a predefined data protocol. The predefined data protocol is modified to define a first segment size and a second segment size. The first segment size represents a minimum segment size that can be transmitted. The second segment size represents a maximum segment size that can be transmitted. A segment is created and transmitted whenever a quantity of time-sensitive information available for transmission allows a segment to be constructed having a segment size between the minimum segment size and the maximum segment size. A segment of any size up to the maximum segment size is also created and transmitted whenever any time-sensitive information is available for transmission and an acknowledgement message is received by the transmitter.Type: GrantFiled: January 14, 2003Date of Patent: October 27, 2009Assignee: QUALCOMM IncorporatedInventors: James M.

Patent number: 7110357Abstract: A method and apparatus for reducing voice latency in a voice-over-data wireless communication system. In a transmitter, data frames are created from audio information by a vocoder and stored in a queue. Prior to storage, some of the data frames are eliminated, or dropped, and are not stored in the queue. In a receiver, data frames are generated from received signals and stored in a queue. Prior to storage in the receiver queue, some of the data frames are dropped. Data frames are dropped either at a single fixed rate, a dual fixed rate, or a variable rate, generally depending on a communication channel latency. By dropping data frames at the transmitter, the receiver, or both, voice latency due to data frame retransmissions is reduced.Type: GrantFiled: July 8, 2004Date of Patent: September 19, 2006Assignee: QUALCOMM, IncorporatedInventors: Yu-Dong Yao, James Tomcik, Matthew B. von Damm, James M.

Patent number: 6990119Abstract: A method and apparatus for allowing a transparent service option transition between at least two wireless communication devices (WCDs). A first communication between a first WCD and a second WCD is established using a first service option. At some point during the first communication, a transition to a second service option, such as an asynchronous data service option, is initiated. At least one of the WCDs provides an identification code to the other WCD using a signaling protocol over the first service option. The first communication is then terminated. A second communication using the second service option is then initiated by one of the WCDs, resulting in a seamless transition to the second service option.Type: GrantFiled: February 7, 2001Date of Patent: January 24, 2006Assignee: Qualcomm, Inc.Inventors: Dan Vassilovski, James Tomcik, Stephen Carter, Yu-Dong Yao, Maria Marshall

Patent number: 6731647Abstract: A method and apparatus for increasing the probability of successful data frame transmission from a transmitter to a receiver. When a data frame is generated by a processor, it is stored in a transmit queue and a copy of the data frame is stored in a secondary queue. An elapsed time device tracks the elapsed time that the data frame copy has been stored in the secondary queue. When no data frames are generated by the processor, data frame copies from the secondary queue are placed into the transmit queue, thereby increasing the redundancy of transmitted data frames and thus the probability of successful transmission to the receiver.Type: GrantFiled: April 17, 2002Date of Patent: May 4, 2004Assignee: Qualcomm IncorporatedInventor: Yu-Dong Yao

Patent number: 6567388Abstract: A method and apparatus for efficient data retransmission in a voice-over-data communication system between a first wireless communication device and a second wireless communication device, without affecting existing infrastructure. When a data frame containing audio information is received in error by the first wireless communication device, n negative-acknowledgement messages are sent from the first wireless communication device to the second wireless communication device which sent the frame, each of the negative acknowledgement messages transmitted in close succession to each other. When a negative-acknowledgement message is received by the first wireless communication device from the second wireless communication device, n copies of the frame identified by the negative-acknowledgement message is transmitted by the first wireless communication device, each of the copies transmitted in close succession to each other.Type: GrantFiled: March 5, 1999Date of Patent: May 20, 2003Assignee: Qualcomm, IncorporatedInventors: James Tomcik, Yu-Dong Yao
