Problems solved by technology

[0010] The problem to be solved by the present invention is to provide a method for measuring the available bandwidth of the IUB interface. Through this method, the IUB bandwidth change situation can be estimated more accurately in the interval time of the IUB bandwidth measurement cycle, so as to overcome the IUB bandwidth in the prior art. There are large changes in the network, the IUB bandwidth is unstable, and the scheduling accuracy is not high.

Abstract

A method for measuring usable bandwidth of IUB interface includes utilizing NodeB to confirm number of current access user and occupation- information of current IUB interface resource, obtaining bandwidth variation value caused by each user at IUB interface and summing up these said variation values to obtain total bandwidth variation, confirming usable bandwidth of current IUB interface according to usable bandwidth information in resource occupation-information of last IUB interface and obtained total bandwidth variation.

Description

technical field [0001] The invention relates to the field of IUB interface bandwidth measurement, in particular to a method for measuring the available bandwidth and interface rate of the IUB interface. Background technique [0002] HSUPA (High Speed ​​Uplink Packet Data Access) technology is a new technology introduced by 3GPP (3rd Generation Partnership Project, third generation cooperation organization) in the R6 protocol to improve the uplink transmission rate. In order to improve the average uplink throughput and capacity of a single user and system, so as to better carry out multimedia services and packet data transmission, this technology adopts NodeB (base station) uplink fast scheduling, HARQ (Hybrid Automatic Retransmission Quest, composite automatic retransmission request) And 2ms short frame technology, the user's uplink throughput rate has been greatly improved, theoretically supporting the highest peak rate of 5.76Mbps, and the system's uplink capacity has also...
