A mobile terminal, in a cellular communication network, comprising a freezing means able, when an on-going call is about to be dropped, to put said on-going call in frozen mode: freezing said on-going call by suspending the data traffic of said on-going call, instead of having said on-going call dropped. A cell, in a cellular communication network, comprising an admission means (AC) able, when an incoming call requests to be hosted, to make a decision by selecting among: - accepting said incoming call in normal mode (NM), - rejecting (RE) said incoming call, - accepting said incoming call in silent mode (SM): servicing all signalling aspects of said incoming call while suspending data traffic of said incoming call. A method, in a cellular communication network for avoiding a call drop.
