Ericsson Certified Associate - Radio Network Optimization Questions and Answers

Question 1

An LTE operator explains that the traffic in cell A is very high compared to the traffic In cell B, which are close to each other. Cells A and B are using the same frequency.

In this scenario, which two actions would balance the traffic between cell A and cell B? (Choose two.)

Options:

A.

Optimize the connected mode mobility parameters.
