In ZTE we have this feature named “Measure BCCH when in subcell2” and abbreviated “SubCell2MeasureBcch”. The description is as follows:
“If this parameter is configured to “Y es”, the system adds a BCCH frequency point for broadcasting this cell in the SACCH system message
of the subcell 2. After the MS reports measurement reports, the system
collects statistics on the sampling distribution of level difference between
the subcell 1 and the subcell 2. If the MR function is enabled, the system
reports the level difference in the MR.”
I am unable to grasp the concept. Can someone shed light on it please. Thank you.
The idea is to force the MS to measure extra frequencies, and send YOU the results, in the form of statistics.
Each MS acts as a drivetest device. The result you get is the difference of rxlev between cell1 and cell2.
What is not clear is whether you can decide what is the frequency you can measure there. In E/ and ALU system, you can force the MS to measure the whole BCCH band, which provide you a very clear picture of cells coverages.
In ZTE, it sounds like it has to be the bcch of the colocated cell only ? Maybe I’m mistaken.
