VoLTE in LBO: Number translation

+1 vote
89 views

In the TR 23.749 (Study on S8HR Architecture for VoLTE), it is mentioned that in LBO integration, calls to non routable local numbers such as local Short-code, 1800XXX services are translated by the VPLMN.

How the translation is done in VPLMN. Is it performed by the P-CSCF?

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?

On which stage the S-CSCF obtain the IFCs from the HSS?
Is it on UE SIP registration or per each call attempt?

In case the IFCs indicates that the S-CSSF should orchestrate the SIP session to two (or more) application server, is there an option to indicate (into the IFCs) that a specific AS should be involved only on specific situation such as: "only in roaming", "only if the dialed number length limited to X digits"
