US 2012/0269062 A1 · APPARATUS AND METHOD FOR CONTROLLING DATA TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM

Abstract

An apparatus and method is provided for controlling data transmission considering congestion in a wired transmission section in a wireless communication system. To this end, a reception device reports, to a transmission device, status information about a congestion status and flag information indicating occurrence of a new congestion status or maintenance of an existing congestion statue. The transmission device reduces throughput of data being transmitted through the wired transmission section, if it is determined from the flag information reported by the reception device that a new congestion status has occurred or the existing congestion status has been being maintained for a predetermined time. The transmission device requests the reception device to report a congestion status, if the congestion status is not released until a lapse of a predetermined time after occurrence of a new congestion status.

Dependent claims

A method for controlling data transmission by a transmission device in a wired transmission section in a wireless communication network, the method comprising:

upon receiving, from a reception device, a report indicating occurrence of a new congestion status in the wired transmission section, reducing throughput of data being transmitted to the reception device through the wired transmission section;
and
upon receiving, from the reception device, a report indicating maintenance of a congestion status in the wired transmission section, reducing throughput of data being transmitted to the reception device through the wired transmission section when the congestion status has been maintained for a predetermined time.

A wireless communication system for controlling data transmission in a wired transmission section, the wireless communication system comprising:

a reception device configured to identify occurrence of a new congestion status or maintenance of an existing congestion status in receiving data through the wired transmission section, and report flag information for identifying the occurrence of a new congestion status or the maintenance of an existing congestion status according to the check results;
and
a transmission device configured to reduce throughput of data being transmitted through the wired transmission section when a report including flag information corresponding to occurrence of a new congestion status is received from the reception device, and upon receiving from the reception device a report including flag information corresponding to maintenance of an existing congestion status, reducing throughput of data being transmitted through the wired transmission section when the congestion status is being maintained for a predetermined time.
