National Roaming KPIs

Hi experts,

Regarding national roaming (NR). If we enabled other operators to camp on our network (all tech 2345G) can we check the roamers KPIs (cssr for roamers, cdr for roamers, traffic for roamers) from let’s say U2000? If not, is it possible to check from CEM(smart care/customer experience management)?

Also, is there anyway where we can control the allocated resources priority and capping the throughput speeds …etc?

Finally, how is this different from MVNO’s and International Roaming in terms of definitions, KPIs, controlling priorities…etc

Note: the operator has a multi-vendor topology (Mainly Eri, Hua and Nokia with mixed RAN- core combinations as well)
