Method and device for reporting received signal strength

Abstract

The invention discloses a received signal strength reporting method and a device. The received signal strength reporting method is not only capable of displaying signal strength accurately and in time on a mobile phone interface, but also capable of mainly no adding current consumption. The device capable of receiving the signal strength comprises a setting unit, a receiving unit, a deviation calculation unit, a first comparing unit, and a first reporting judgment unit, a minimum value unit, a second comparing unit and a second reporting judgment unit.

Description

technical field [0001] The present invention relates to the field of mobile phone signals, in particular to a method and device for reporting received signal strength indicators (Received Signal Strength Indicator, RSSI for short) with more accurate cell phone signal strength grids. Background technique [0002] In the current reporting method of received signal strength at the bottom layer (mobile phone baseband), basically, a threshold value for reporting received signal strength is set, which is usually 5dBm. When the mobile phone system finds that the current value of the received signal strength has a change greater than or equal to 5dBm from the previously reported received signal strength value, it will report to the upper layer (mobile phone interface), and the mobile phone interface will display the corresponding signal number according to the reported received signal strength value . Such a reporting method will have the following problems: For example, the receiv...

Problems solved by technology

Such a reporting method will have the following problems: For example, the received signal strength value reported last time is -96dBm, (Note: -100dBm to -95dBm, the number of signal grids is 2, and -96dBm is in the range of grid numbers of 2), the receiving The current value of the signal strength is -92dBm (-90dBm to -95dBm, the number of signal bars is 3, -92dBm is in the range of 3 bars), -92dBm to -96dBm, the change of 4dBm is less than the reporting threshold of 5dBm, so it is not reported

If the received signal strength reporting threshold is set to 1dBm, it will be reported to the upper layer once the received signal strength changes. Although the signal strength grid can be displayed accurately and in time, such frequent reporting will increase the current consumption.
