Abstract

A method for reconfiguring receiving window size of a receiving end of a communication system in a transmitting end of the communication system includes receiving a status report unit from the receiving end and updating an acknowledge state variable and a maximum send state variable according to the status report unit. Positively acknowledged packets with sequence numbers greater than the acknowledge state variable are retained in a buffer of the transmitting end. Positively acknowledged packets with sequence numbers greater than the acknowledge state variable are marked by the transmitter end as positively acknowledged packets. The maximum send state variable is updated according to a command for reconfiguring receiving window size of the communication system. Positively acknowledged packets with sequence numbers greater than or equal to the maximum send state variable are marked as not yet acknowledged packets.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 594,697, filed Apr. 29, 2005, and included herein by reference.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention is a method and a device of a procedure for reconfiguring receiving window size of a receiver in a transmitter of a communications system. When the receiver discards packets that are outside the receiving window and have been positively acknowledged, the present invention prevents the transmitter from discarding the packets and hence prevents initiating a reset procedure. Therefore the communications system maintains a robust and efficient transmission.

[0004] 2. Description of the Prior Art

[0005] With the coming of the information age, requirements of mobile voice, data communications, and various mobile services increase each day. Communications systems of prior art are facing bottlenecks of channel usage over...
