Abstract
There is disclosed a manner of controlling traffic by admission control in a communication network such as one operable according to GSM standards. When a call setup request is received from an MS, the BSC forwards the request to an MSC, which selects a MGw that is accessible to the BSC via an IP backbone. When notified of the MGw selection, the BSC runs an algorithm to assess the transmission quality of the IP backbone toward the MGw. The BSC then determines whether to reject the call setup request depending on whether the quality level is acceptable as determined by the algorithm. If the call setup proceeds, the MGw may run a similar algorithm to assess the quality of the IP backbone toward the BSC. The BSC and MGw may also check their own bandwidth limitations prior to running their respective algorithms.
