What Is the Overall Procedure for Inter-Frequency MLB?

Question

What is the overall procedure for inter-frequency MLB?

Answer

The overall procedure for inter-frequency MLB can be divided into the following phases: MLB triggering, candidate cell selection, target frequency selection, UE selection, load transfer, and MLB termination. Figure 1-1 illustrates the overall procedure.

Figure 1-1 Overall procedure

Note: Load information exchange in the blue circle is present only in exchange mode.

After the MLB algorithm is enabled, the eNodeB starts load measurement and evaluation in real time. After MLB is triggered, the MLB algorithm performs the procedure shown in Figure 1-1 within each period specified by the CellMLB.InterFreqLoadEvalPrd parameter. When the MLB termination conditions are met, the MLB algorithm immediately stops the ongoing MLB operations.
