  • Automatic data transfer mode control
    Patent number: 6181686
    Abstract: The method according to the invention relates in general to transmission in cellular telecommunication systems and in particular to optimization of the data transfer mode. In the method according to the invention the data transfer mode is controlled using the downlink quality measured by the mobile station (MS) and the uplink quality measured by the base station (BTS). For transparent connections it can be determined a desired maximum threshold for the RXQUAL value, and when the uplink or downlink RXQUAL exceeds that maximum threshold (ie. the bit error rate BER exceeds the maximum value), a more error-tolerant channel coding of a lower transmission speed is taken into use and the channel resources available are increased e.g. by growing the number of time slots to keep the user data transmission rate constant.
