Problems solved by technology

However, this method is only completed in individual cells. Although a cell does not need to reduce the reverse rate, when the users of this cell interfere with other critical cells, the interference cannot be effectively controlled.

Embodiment Construction

[0016] In order to solve the disadvantages of the traditional technical solutions, the present invention further elaborates the control method of the reverse rate in an evolution data optimization system according to the present invention through the following examples. The specific implementation is described in detail below, but it is not intended as an explanation Limitations of Invention.

[0017] On the basis of the existing reverse link rate control method, the method described in the embodiment of the present invention introduces a system control method to perform linkage control on each cell and control the reverse rate of each area, so as to control the reverse link rate of the entire coverage area. The performance is optimized to reduce the interference of the mobile phone to the antenna port of the base station.

[0018] The method described in the embodiment of the present invention performs linkage control on each cell under the base station of the EVDO system, th...

Abstract

The invention discloses a control method of a reverse rate in an evolution data optimization system. The method comprises the following steps: detecting whether reverser rate overload of a cell exists under a base station of the evolution data optimization system; if yes, processing the cell neighboring to the cell with the reverser rate overload as a condition of the reverse rate overload. The method adopts a system linkage control method, which not only can ensure the maximum reverse performance in each cell coverage area, but also can prevent impact of a plurality of base stations or neighbor cells on other base stations during the reverse overload.

Description

technical field [0001] The present invention relates to an EVDO (Evolution-Data Optimized, evolution-data optimization) system, in particular to a method for controlling the reverse rate in the evolution-data optimization system. Background technique [0002] The EVDO technology under the CDMA standard is one of the mainstreams of the third generation (3G) and future wireless communications. It is gradually occupying the market and commercialized in some developed countries such as North America and Europe. The version of EVDO technology has been developed from Rev0 to RevA. Its downlink rate has grown from 2.4Mbps in Rev0 to 3.1Mbps in RevA, and its uplink rate has grown from 153.6Kbps in Rev0 to 1.8Mbps in RevA. It truly has the practical significance of unlimited broadband. This technical parameter makes mobile TV, video on demand, video intercom, and mobile broadband Internet access possible, and will drive and develop a number of emerging industries, such as: mobile TV ...
