在GSM通讯系统中,可用无线信道数远小于潜在用户数,双向通讯的信道只能在需要时才分配。这与规范电话网有很大的差异,在电话网中不论有无呼叫,每个终端都与一个交换机相连。

(In the GSM communication system, the number of available wireless channels is far less than the number of potential users, and the channels for two-way communication can only be allocated when needed. This is very different from the normative telephone network, in which each terminal is connected to a switch whether there is a call or not.)
