Think about the concepts GSM uses (as do most mobile phone systems) - it has a number of cell sites that service a number of mobile phones. The cell site is the master and polls the phones in its area. And so it goes on up the tree: Each cell site (BTS) is a slave to a Base Station Controller (BSC) - and one BSC controls many BTS. Each BSC, in turn, is a slave to an MSC - and one MSC controls many BSC: https://styx.uwaterloo.ca/~jscouria/GSM/gsmreport.html |
