GNB ID lenght

Hello dears, I was discussing with my colleagues regarding a request customer made from changing the gnbid lenght from 22 to 28bits. We were trying to find out the impacts besides the cell id range reduction.Our network has NSA and hybrid (NSA_SA) gnodebs.We are considering change the id lenght for all related sites. We are also thinking about in a ran sharing scenario in the future… If the sharing operators consider different gnbid lenghts for each network, do you guys see another possible impact (other than the cell id range reduction) if the chosen gnbid and cell id values met the requirements for both of them? Thanks

Depends on ecgi length, ecgi should be of 28 bit mccmnc enbidceillid combination
