Why is handover taking place from 2nd carrier to 1st carrier while reselection is taking place from 1st carrier to the 2nd?!


#1

Hi
Here in UMTS two carriers are there,I should get inter-frequency handover from 2nd carrier to 1st carrier. But while cell reselection between two cells it’s going to 1st carrier instead of second carrier.
What is the reason?

Can I get it by reducing the power of 1st carrier


#2

U might check the traffic balance between the 2 carriers

Usually 1 carrier ecno is poorer than 2nd carrier and the 2 cell might not have the same coverage raduis

If there is traffic imbalance you might want to add offset for the overloaded cell

I would not recommend power since u will ultimately lose coverage…


#3

Doing in midnight usually no traffic


#4

No traffic on 2nd carrier?


#5

Yes, there is no traffic


#6

Can be a single RRU be of dual technology?


#7

Yes, if u have a RRU supporting 2 tecnologys, like 2G and LTE 1800. But in 2 differents BBUs


#8

In Huawei you can use the same BBU with higher UBPB board configuration and operate the GL mode on the same RRU


#9

Nice … :metal:


#10

E/// supports GUL on one baseband


#11

Is the Blade RRU


#12

Yes. RRU3953 can support 1800 GSM and LTE together


#13

@Whatasppuser3, have you any documentation about this function?

@Whatasppuser3, possui/poderia compartilhar algum documento técnico que trate deste hardware Huawei?


#14

Here E////
Single RRU supports Umts 900 and Lte 900 bands.
Is it possible ?


#15

I’ll check it tomorrow and share with u guys


#16
