Abstract
Token bucket algorithm is a common algorithm used for traffic shaping and rate limiting. In LTE (Long Term Evolution) system, RRC (Radio Resource Control) layer configures priority, PBR (prioritisedBitRate), and BSD (bucketSizeDuration) for every logical channel so that lower priority channel can also get resource and bursting data can be sent in a short time. This paper firstly introduces application of token bucket algorithm in LTE system. And the test procedure is designed to test the algorithm. Test result shows that the algorithm is used in LTE system successfully. The algorithm has been used in TD-LTE radio frequency conformance testing instrument.
