METHOD AND COMMUNICATIONS ARRANGEMENT FOR SETTING UP A PUSH-TO-TALK COMMUNICATIONS LINK AND PUSH-TO-TALK CLIENT UNIT.

摘要

Within the scope of a setup of a push-to-talk communications link, a link setup message is transmitted from a first push-to-talk client unit to a push-to-talk server unit. The link setup message contains a mode information item which specifies whether the client unit desires a setup of the communications link in the unconfirmed indication mode or in the confirmed indication mode.
