Abstract:
1. A method of transmitting data packets between a mobile terminal and a network node of a convergent communications network through a first channel residing in a first transmission medium using a first transmission technology and a second channel residing in a second transmission medium using a second transmission technology for a user service, the first and second transmission technologies differing in transmission mode, transmission standard, or transmission protocol, the method comprising the steps of: establishing the first channel between the mobile terminal and the network node, establishing the second channel between the mobile terminal and the network, transmitting the data via the first channel in a continuous data stream in which a predetermined number of data packets per unit of time is always present, checking the transmitted data for different fault types by a fault detector within monitoring time windows of different time lengths each for a respective one of the different fault types in order to assess transmission quality, simultaneously checking with a switch in the mobile terminal or in the network node whether the number of faults in each of the monitoring time windows exceeds a total fault limit value of all fault types and whether the number of faults of each fault type in the respective monitoring time window separately exceeds a respective predefined limit value, and when the fault number exceeds the total fault limit value or when two or more limit values are exceeded simultaneously in the monitoring time windows, the switch, while maintaining the transmission of the predetermined number of data packets per unit of time whenever the limit value is exceeded moves the data transmission to the second channel.
