Patent ID: 7539460

Claim:
A method for determining an error rate of a mobile-telephone device under test with a recognition of an assignment signal for the assignment of one of several mobile-telephone devices of the same transmission channel to a subsequent transmission block of the transmission channel, comprising the steps of: transmitting a transmission block with an assignment signal; receiving the assignment signal by the mobile-telephone device under test; determining by the mobile-telephone device under test whether the subsequent transmission block has been assigned to it by the received assignment signal; transmitting, by the mobile-telephone device under test, a message signal in the subsequent transmission block, if an assignment has been established; receiving the message signal from the mobile-telephone device under test in the corresponding transmission block; checking, after an assignment signal, which addresses the mobile-telephone device under test, whether a message signal from the mobile telephone device under test has been received in the subsequent transmission block; determining a number of unrecognized assignment signals addressing the mobile-telephone device under test, wherein the assignment signal to be transmitted is selected from an assignment signal addressing the mobile-telephone device under test and at least one other assignment signal addressing another mobile-telephone device of the same transmission signal; determining a number of assignment signals incorrectly recognized by the mobile-telephone device under test as an assignment, which address other mobile-telephone devices of the same transmission channel; and determining an error rate from the number of assignment signals incorrectly recognized as an assignment.
