How the preemption works in volte network?

0 votes
29 views

For each bearer in volte there are QCI and ARP parameters, for example default bearer qci 9 arp value, qci 5 arp value, qci 1 arp value, and the ARP has the PCI and PVI parameters too.

So in volte network if we need to have a VIP user how will be the mapping between QCI and ARP values?
And this ARP values need to be configured in the Hss for the user and also in the PCRF?
