Method, equipment and system for sharing transmission bandwidth among different systems

Abstract

The embodiment of the invention provides a method, equipment and system for sharing transmission bandwidth among different systems, belonging to the field of communication. When a first communication system and at least another communication system share the transmission bandwidth, the method comprises the following steps that: 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 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 method provided by the invention solves the problems that equal distribution of bandwidth can not be ensured when two systems share the transmission bandwidth, and the two systems compete for the shared bandwidth, thus being unfavorable for improving the utilization efficiency of bandwidth.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, equipment and system for sharing transmission bandwidth between different systems. Background technique [0002] In an actual network, UMTS (Universal Mobile Telecommunications System, universal mobile communication system) base station (NodeB, UTRAN node B) and LTE (Long Term Evolution, long-term evolution) base station (eNodeB, E-UTRAN node B) may be deployed at the same site, At this time, the Iub interface between RNC (Radio Network Controller, radio network controller) and NodeB and the S1 interface between SAE (System Architecture Evolution, system architecture evolution) and eNodeB share the bandwidth of the last distance of ground transmission (such as figure 1 shown). Usually, the transmission cost of the base station is expensive and the bandwidth is limited, and a reasonable mechanism is required to allocate the shared transmission bandwidth between the UMT...

AI Technical Summary

Problems solved by technology

Usually the transmission cost of the base station is expensive and the bandwidth is limited. There needs to be a reasonable mechanism to allocate the shared transmission bandwidth between the UMTS base station and the LTE base station.

[0003] In order to solve the above problems, there is currently an existing technology that uses the RNC and SAE to perform traffic shaping according to their respective configured bandwidths. The disadvantage of this method is: if the traffic of UMTS services is very large, close to the total transmission bandwidth, then LTE traffic will be small and may be starved to death

[0004] However, it can be seen from the prior art introduced above that the common transmission bandwidth allocation scheme among network elements of different systems in the prior art does not solve the problem of realizing fair allocation of transmission bandwidth shared between UMTS and LTE systems to improve transmission bandwidth efficiency question
