Question
GSM uses TDMA. When you are not making a call, are you still put in a time slot or you only be in a time slot when you make a call? If not, how is it still connected to the network? Am I making sense? Thanks

Answer
Hi

Good question.

In GSM we have two parts, Signaling and Traffic. What you asked is true when the concept is traffic but before or after that, always users or better to be said terminals have signaling connection with network via signalling channels. with this signaling transaction, users' conditions (such as location, handover, roaming, status,...) is live in network.

for Cell planning, at least one TRX is allocated just for signaling.

Best,

Wireless Communications
