1. A method for setting up a push-to-talk communications link between a first push-to-talk client unit and at least one second push-to-talk client unit, the method comprising:
- transmitting a push-to-talk connection setup message from the first push-to-talk client unit to a push-to-talk server unit, wherein the push-to-talk connection setup message contains a push-to-talk mode information item with which it is specified, whether the requested push-to-talk communication link should be built in a push-to-talk confirmed mode or a push-to-talk unconfirmed mode, wherein an enable signal is transmitted to the first push-to-talk client unit to enable transmission of useful data depending on a communications link mode from the push-to-talk server unit at different times within the scope of the setup of the push-to-talk communications link; and
setting up the push-to-talk communications link from the push-to-talk server unit to the at least one second push-to-talk client unit taking into account the push-to-talk mode information in the push-to-talk connection setup message.

Abstract
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.

10. A push-to-talk client unit having:
-
a unit for forming a push-to-talk link setup message, wherein the push-to-talk link setup message contains a push-to-talk mode information item with which it is specified, whether the requested push-to-talk communication link should be built in a push-to-talk confirmed mode or a push-to-talk unconfirmed mode, wherein the first push-to-talk client unit receives an enable signal for transmitting useful data as a function of the communications link mode from a push-to-talk server unit at different times within the scope of the setup of the push-to-talk communications link, and a transmitter unit for transmitting the push-to-talk link setup message to a push-to-talk server unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A communications arrangement for setting up a push-to-talk communications link between a first push-to-talk client unit and at least one second push-to-talk client unit, having:
-
a first push-to-talk client unit which has; a unit for forming a push-to-talk link setup message, wherein the push-to-talk link setup message contains a push-to-talk mode information item with which it is specified, whether the requested push-to-talk communication link should be built in a push-to-talk confirmed mode or a push-to-talk unconfirmed mode, wherein the first push-to-talk client unit receives an enable signal for transmitting useful data as a function of the communications link mode from a push-to-talk server unit at different times within the scope of the setup of the push-to-talk communications link, and a transmitter unit for transmitting the push-to-talk link setup message to the push-to-talk server unit; wherein the push-to-talk server unit has; a receiver unit for receiving the push-to-talk connection setup message, and a unit for setting up the push-to-talk communications link to the at least one second push-to-talk client unit according to the push-to-talk mode information in the push-to-talk connection setup message, and wherein the at least one second push-to-talk client unit has; a receiver unit for receiving the push-to-talk link setup message, and a transmitter unit for transmitting push-to-talk messages to the push-to-talk server unit. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
