AI Technical Summary

Technical Problem

Existing multi-system combining platforms cannot effectively control POI input power in a multi-standard coexistence environment, resulting in uncontrolled intermodulation interference levels, affecting network performance and user experience.

Method used

By receiving RF signals, performing signal coupling and power detection, it is determined whether the power intensity exceeds the maximum power threshold configured by the network management. If it exceeds, attenuation control is performed and the power attenuation value is calculated to adjust the output power of the direct signal to achieve dynamic adjustment.

Benefits of technology

Effectively avoid POI interference, optimize signal quality, reduce intermodulation interference, improve resource utilization efficiency, and enhance user experience.

Abstract

The present invention discloses a calculation method, dynamic adjustment method, device and platform for the input power of a multi-system combining platform. The calculation method includes the following steps: receiving an input RF signal; performing signal coupling on the input RF signal to obtain a coupled signal and a direct signal; detecting the power intensity in the coupled signal; judging whether the detected power intensity exceeds the maximum power threshold value configured by the network management: if the detected power intensity exceeds the maximum power threshold value configured by the network management, performing attenuation control and calculating the power attenuation value; if the detected power intensity does not exceed the maximum power threshold value configured by the network management, performing no attenuation control; calculating the output power of the direct signal after attenuation according to the power attenuation value; using the output power of the direct signal after attenuation as the input power of the multi-system combining platform to complete the dynamic adjustment of the input power of the multi-system combining platform. This method can limit the input power of POIs, thereby effectively avoiding POI interference problems.
