Measurement Control / WCDMA to GSM

 

At high level, it is simple to understand overall flow of Measurement Control/Measurement Report. But if you are asked to create the measurement control message on your own, then you would understand how tricky it is. so it would be very helpful to see many example that has been verified. I will keep adding more examples as I have chance.

 

 

 

Example : WCDMA to GSM with Event 3c >

    WCDMA Cell Configuration :

    • Band = Band 2

    • Radio Bearer : 384/64

     

    GSM Cell Configuration :

    • NCC = 0

    • BCC = 1

    • Band = P-GSM 900

    • CCH ARFCN = 5

    • TCH ARFCN = 10
