Hello Experts,
I have a case.
We need to make one carrier to be impossible for idle selection and reselection.
Any suggestions?

2

Make cell as barred.

3

But will it be available for HO?

4

Yes, no issues for HO.

5

Make cell access for operator only ie only class 15 sim cards.

6

Is it possbile to set via parameter?
Vendor is Huawei.

7

This involve configuration change in CORE.

8

So only will take effect on idle mode, connected will be fine, right?

9

Yes, no issues for connected mode.

10

Turn off the carrier.

11

Bar the carrier cell.
Which tech is this?

12

It will be ok, if it is LTE, u can even use it for carrier aggregation with some additional features.

Somes solutions to make one carrier unavailable for selection/reselection (idle mode) such as:
1, set cell barred: all UE can not access this cell
2, restrict some access class: normal AC are 10-15
3, reserve LTE cell: in this case, only UE has high-priority RRC establishment can access cell. HSS can set this kind of UE
4, Set rx-lev-min to very high level, such as -20dbm. So almost UE can not access.
