Facing auto latching issue in 4g


#1

facing auto latching issue in 4g. Vendor E//. what should be check


#2

Auto latching?


#3

Yes…3g to 4g


#4

Check idle mode reselection priority for eutran and sanity of definitions…In 3G


#5

i have checked & found lte set priority level 6 in nodeb


#6

What is priority of utran?


#7

The priority is 4


#8

So you have higher priority of LTE, then system is working fine…Reverse it if you wanna otherwise.


#9

but 3g to 4g cell reselection not happening. but forcefully latch to 4g happening


#10

You were telling it’s auto latching…now you are saying that it’s forcefully done.


#11

in handset if we set only 4g it is latching but if we set 4g/3g/2g mode then it is latching to 3g .not going to 4g


#12

Ok…what are bands of 3g and 4g. Also how many carriers at 3g are deployed. Which carrier ue is camped? Check eutran definition in that sector. It should have correct definition for eutran and higher priority for it.


#13

3g 900 band
4g 2100 band
single carrier


#14

Did you reset the cell after setting priorities? What is the priority for eutran you are receiving in L3?


#15

Pls suggest further


#16

Share SIB19 from L3.
