Abstract:
1. A method of transmitting data with real-time requirement and data without real-time requirement, which comprises: providing a plurality of first quality of service classes in an application layer for transmitting first data with real-time requirement and a plurality of second quality of service classes in the application layer for transmitting second data without real-time requirement, said first data with real-time requirement being of a different type from said second data without real-time requirement; selecting a combined quality of service class formed from the first quality of service classes and the second quality of service classes in the application layer, each combined quality of service class being allocated transmission parameters specifying a transmission of the first data and the second data; and supplying the first data and the second data and the transmission parameters of the selected combined quality of service class to a unit of a transport layer, and transmitting the first data and the second data with the unit taking into consideration the transmission parameters; wherein selecting the combined quality of service class comprises: a) selecting a combined quality of service class having the first quality of service class with a highest first priority and the second quality of service class with a highest second priority; b) checking whether a coder to be used can transmit the first data and the second data according to the transmission parameters of the respective combined quality of service class and available bandwidth; c) if the checking step results in an affirmative answer, selecting the combined quality of service class; d) if the checking step does not result in an affirmative answer, selecting a further combined quality of service class such that in each case the combined quality of service class with reduced second priority is selected; and e) iteratively performing steps b) and d) until the coder can transmit the first data and the second data in accordance with transmission parameters of the respective combined quality of service class.
