Transmission mode selecting method for use over communication network, involves transmitting selected modes to call control and initiating further selection of mode, where transmission of user data is performed using further selected mode

摘要

The method involves transmitting transmission modes of communication devices to a service quality mechanism (DGE) and selecting a number of modes from the list based on available transmission resources such that quality of service is guaranteed by the resources. The selected modes are transmitted to a call control and a further selection of the mode is initiated. The transmission of user data is performed using the further selected mode. An independent claim is also included for a communication system for selecting a transmission mode for transmission of user data between communication devices over a packet oriented communication network.
