Method and apparatus for measuring and optimising the quality of data transmission
First Claim
1. A method for testing the functioning of downlink data communication in a cellular radio system, comprising the steps of:
- sending a test signal from a base station to at least one mobile station, receiving the test signal sent by the base station at a mobile station, comparing the test signal received at the mobile station to a known form of the test signal, producing and temporarily storing at the mobile station information about errors which were detected in the received test signal during the comparing step, sending information representing the stored information about errors from the mobile station to a base station, receiving the information sent by the mobile station at a base station, storing in the cellular radio system the information received by the base station, generating a test signal, which is a pilot signal, and which is transmitted, via a base station of the cellular radio system, to a mobile station of the cellular radio system, generating and storing at the mobile station information describing the occurrence of errors in the test signal received by the mobile station, transmitting from the mobile station to the base station a first error message describing the occurrence of errors within a given block of data of the test signal received by the mobile station, and transmitting from the base station to a certain control unit a second error message describing the first error message received from the mobile station of the cellular radio system.

Abstract
The invention concerns a method and associated hardware units for testing the functioning of downlink data communication in a mobile station (202, 802, 902). The mobile station is equipped for receiving (302, 805) a signal in the downlink direction and for sending (312, 808) a signal in the uplink direction. As a part of the method, a test signal (711, 715, 716, 805) is received in the downlink direction. The received test signal is compared (208, 713, 908) to a known form of the test signal. There is produced and temporarily stored (209, 806, 909) information about errors which were detected in the received test signal during the comparing step. In the uplink direction a signal is sent (714, 717, 808) representing the stored information about errors.
