    摘要： The invention relates to a method for load control and a radio system. In the invention a load result describing the load is cell-specifically formed. The load result is formed either by comparing a signal strength of desired signals and a combined total strength of interferences and the desired signals or by weighting a signal-to-interference ratio with a bandwidth or a data transmission rate. The load result is compared with a threshold value of the highest load level allowed of a cell. The data transmission rate in the cell is increased if the load result is smaller than the threshold value. The data transmission rate in the cell is reduced and the establishment of new connections is avoided if the load result exceeds the threshold value. In heavy load situations a signal-to-interference objective is also changed in order to balance the load result.

    摘要： The invention relates to a method for load control and a radio system. In the invention a load result describing the load is cell-specifically formed. The load result is formed either by comparing a signal strength of desired signals (23) and a combined total strength of interferences (13) and the desired signals (23) or by weighting a signal-to-interference ration with a bandwidth or a data transmission rate. The load result is compared with a threshold value of the highest load level allowed of a cell (1). The data transmission rate in the cell (1) is increased if the load result is smaller than the threshold value. The data transmission rate in the cell (1) is reduced and the establishment of new connections is avoided if the load result exceeds the threshold value. In heavy load situations a signal-to-interference objective is also changed in order to balance the load result.

    摘要翻译： 本发明涉及一种负载控制和无线电系统的方法。 在本发明中，描述负载的负载结果是特别形成的。 负载结果是通过将期望信号（23）的信号强度与干扰（13）的组合总强度和期望信号（23）进行比较，或通过对具有带宽或数据的信号与干扰比例进行加权而形成的 传输速率。 将负载结果与单元（1）允许的最高负载水平的阈值进行比较。 如果负载结果小于阈值，则单元（1）中的数据传输速率增加。 如果负载结果超过阈值，则小区（1）中的数据传输速率降低，并且避免建立新的连接。 在负载较重的情况下，也会改变信号对干扰目标，以平衡负载结果。

    摘要： The invention relates to a method for improving the reliability of a handover and call establishment in a cellular radio system which comprises at least one base station in each cell, and a group of subscriber terminal equipments which communicate with one or more base stations. The base stations measure the total interference level of signals they have received from the terminal equipments, and transmit a pilot signal with a known transmit power. The terminal equipments measure the power levels of pilot signals received from different base stations. In the system at least some transceivers comprise circuitry for estimating, by means of the pilot signals, the path loss between the terminal equipment and the base stations. To improve the reliability of the handover and call establishment, at least some transceivers in the system of the invention estimate the signal to noise ratio between the terminal equipment and the base station in the uplink transmission direction on the basis of the total interference measured at the base station, the path loss, and the terminal equipment transmit power.
