Method and apparatus for efficient data transmission control in wireless voice-over-data communication system

Abstract

A method and apparatus for efficient data transmission in a wireless voice-over-data communication system. 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 (308) and the maximum segment size. A segment of any size up to the maximum segment sizes is also created (306) and transmitted whenever any time-sensitive information is available for transmission and an acknowledgement message is received (304) by the transmitter.

Description

technical field [0001] The present invention relates generally to the field of wireless communications, and more particularly provides an efficient method and apparatus for transmitting time-sensitive information in a data-based voice communications system. Background technique [0002] The field of wireless communications has many applications including cordless telephones, radio paging, wireless local loop and satellite communication systems. One particularly important application is the cellular telephone for mobile users. (The term "cellular" is used here to include both cellular and PCS frequencies.) Various over-the-air interfaces have been developed for such cellular telephone systems, including frequency division multiple access (FDMA), time division multiple access (TDMA), and code division multiple access (CDMA). In connection with this, various domestic and international standards including Advanced Mobile Phone Service (AMPS), Global System for Mobile Phones (G...

AI Technical Summary

Problems solved by technology

[0008] If the selected TCP or UDP minimum segment size is relatively large, the latency is increased since segments are only sent when the minimum segment size is reached

On the other hand, if the selected TCP or UDP minimum segment size is relatively small, there will be a significant consumption of processing resources in the sender, which will have to process many of the segments required to send even a small amount of information.
