摘要
According to a method for operating a push-to-talk session between at least a first terminal (UE1) and a second terminal (UE2, T) by use of a push-to-talk server (PTTSv) of a cellular radio communications system, data of the push-to-talk session is transferred via the push-to-talk server (PTTSv) from the first terminal (UE1) to the second terminal (UE2, T) and vice versa. According to the invention the push-to-talk server (PTTSv) processes data of the push-to-talk session in at least a first data format (FSIP, FRTP, FRTCP), the cellular radio communications system receives data (D2, D3C, D3U, VM, SD) of the push-to-talk session from the second terminal (UE2, T) in at least a second data format (FSMS, FSS7, TDM) and an interworking unit (IWU) converts data from the second data format (FSMS, FSS7, TDM) into the first data format (FSIP, FRTP, FRTCP) and vice versa.
