[srslte-users] how to ensure commercial ue online for a long time

[Jane Zhang]

Dear srsLTE team
I run srsenb and srsepc on a machine( Jetson TX2). RF-end is LimeSDR USB.
Then I use iphone with a programmable card connected to enb.  To confirm if
it works well,  I use ping on both iphone and epc. It is ok.

The first test is:
I did a test. when ue is near enb, when ue open an app to request audio
from internet. The same as above, the signal became weak. Then the
connection is broken. Attached the log files.

The second test is:
when ue is near enb ( the distance is 1 meter), it works well.  (command
ping is ok. it last for a long time)
when ue becomes far a little (3-4 meters), the connection is unstable. I
saw the signal became weak. After 1 minute, the connection is broken.

My question is how to maintain the connection is stable (without broken).

Could someone help?  Thank you so much!
