<p>Provided are a method, device and system for sharing transmission bandwidth among different systems, which belong to the field of communications. When a first communication system and at least another communication system share the transmission bandwidth, the method includes: a first network element in the first communication system compares the sum of rates for sending services to a second network element in the first communication system with the bandwidth preset for the second network element; the first network element adjusts the transmission priorities of services sent to the second network element according to the comparison result; and the first network element adjusts the sending bandwidth for transmitting services to the second network element according to the transmission congestion state of the first communication system. Therefore, the problems that fair bandwidth allocation cannot be ensured when two systems share the transmission bandwidth, and the competition for the shared bandwidth is unfavourable for improving the utilization efficiency of bandwidth.</p> |
