Method of determining an error rate and a suitable testing device

摘要

The invention relates to a method and to a test device (12) which is used to determine an error rate during the transfer of data (1) in a mobile radio system. Said mobile radio system comprises at least one transfer channel, wherein several data partial flows (2.1, 2.2, 2.6) are transferred. The several data partial flows (2.1, 2.2 . . . 2.6) are produced in a signal generator unit (8). A transport format is determined, in an individual manner, for each data partial flow (2.1, 2.2 . . . 2.6). The data partial flows (2.1, 2.2 . . . 2.6) are sent, respectively, to a number of transfer blocks which belong together (5.1, . . . 7.1). A device which is to be tested captures the transfer blocks (5.1, . . . 7.1) of the data partial flows (2.1, 2.2 . . . 2.6) and evaluates them. According to the accuracy of the evaluation, a positive or negative actuation signal (ACK, NACK) is sent back by the device which is to be tested. An error rate of each data partial flow (2.1, 2.2 . . . 2.6) is determined by the test device (12) from the actuation signals (ACK, NACK) which are captured by the test device (12).

1. A method of determining an error rate in a data transfer in a mobile radio system having at least one transfer channel in which a plurality of data subflows is transmitted, comprising the following method steps:
generating the plurality of data subflows by a signal generator unit, specifying transport formats individually for each data subflow, transmitting the data subflows in a number of associated transfer blocks in each case to a device to be tested by a testing device, receiving and evaluating the transfer blocks by the device to be tested and sending back a positive or negative confirmation signal for every transfer block, determining an individual error rate for every one of the plurality of data subflows from the received confirmation signals of transfer blocks associated with all the data subflows by the testing device, wherein the method comprises the testing device individually specifying for every data subflow a sequence of redundancy versions for the transfer blocks to be repeatedly transferred, and the testing device individually specifying the redundancy version sequence for a data subflow independently of positive or negative confirmation signals sent back to the transfer blocks of said data subflow.
