Drop Call Rate
The Dropped Call Rate (DCR) - also called Call Drop Rate - is the number of dropped calls divided by the total number of call attempts. A dropped call is a call that is prematurely terminated before being released normally by either the caller or called party (i.e., the call is dropped before the exchange of Released Message 'RL_M' and Released Complete Message 'RLC_M' in the signaling flow).
