Strange peaks during 10,24s eDRX

[GiulianoFranchetto]

Hi,

We are now testing the new eDRX provided by our operator.

We are analyzing the current consumption depending on the eDRx period to choose the best eDRX configuration for our use case.

When analyzing the consumption chart, I've found something very strange that only happens with eDRX = 10,24s

There are 3 peaks every 10,24s instead of one.

With 5,12s there is only 1 peak at every period.

Here is the graph for 5,12s:

Here is the graph for 10,24s

Because of the 3 peaks, the average power consomption of the 10,24s is higher than the consomption with 5,12s, which is not really what I expected.

Do you have some insight on what is happening here?

Regards

Giuliano

Hi,

 

The eDRX has a paging time window which occurs n times after the eDRX cycle, which seems to be 3 of at 10.24, while its only 1 at 5.12 sec.

What are you requesting (see this AT cmd to see your _requested_ settings) and what is the network is applying (see this AT cmd for checking your current setting)?

 

Kind regards,

Håkon
