Abstract
The invention relates to a method for establishing a push-to-talk-(Ptt) communication link between two Ptt devices (), in which the data of different types, such as voice data (Sp), audio data (A), video data (V) etc., is transmitted between the Ptt devices (). The first Ptt device () transmits a Ptt link request, and subsequently a communication link is established for at least one selection of said different types of data via a communication channel (F, NF) according to a communication protocol. According to the invention, the Ptt link request contains priority information which enables the data types to be allocated a transmission priority, and the communication protocol only authorizes the communication channel (F, NF) to be established if the second Ptt-device () is available for the data type or for the data types having the highest transmission priority. The transmission of one data type, which has a lower transmission priority, by means of said communication channel (F, NF) is only authorized if the second Ptt-device () is available for said data type, and the second Ptt-device () is also available for all data types with a higher transmission priority.
