The multi - channel sharing means that any idle channels can be occupied to communicate by any users in the system , therefore the user numbers in the system could be more than the channel numbers . adopting the multi - channel sharing technique makes the channel utilization ratio increase and the call congestion phenomenon emerge at the same time
多信道共用意味着系统中的任一空闲信道可为任一用户所用，因而系统可以容纳比信道数更多的用户数，使信道利用率得到提高，与此同时也不可避免呼损现象的产生。
