MC7455 Low LTE Usage

Dear Engineers

We’ve got a serious problem while we are using MC7455 to calculate cellular usage of our local mobile operator,but it sounds everywhere ,LTE usage is excessively lower than the real usage while 3G usage is about 90%, we were thinking this kind of modem just consider LTE-advanced usage but we are roughly sure that it’s true. Is it possible a missing in modem’s configuration?

I would be greatly sincere if anyone can help us through this problem .
