How to make the dispatchertimer run in the background?

Question

Windows phone

I stumbled upon a question on a cyber forum (A new problem has appeared, the dispatchertimer does not work in the background. When the phone screen goes blank, the timer stops, well, it does not work when you switch to another application.)
I became very interested in the solution

OS stops - windows phone 8.1
