Upon receipt of the AS identifier (e.g., an active AS name AVP) from the HSS, the second S-CSCF node can send the SIP request to the AS in order to restore the communication session for the UE.

Abstract: Fifth Generation (5G) Millimeter Wave (mmWave) cellular networks are expected to serve a large set of throughput intensive, ultra-reliable, and ultra-low latency applications. To meet these stringent requirements, while minimizing the network cost, the 3rd Generation Partnership Project has proposed a new transport architecture, where certain functional blocks can be placed closer to the network edge.

To meet the ultra-reliable and low-latency requirements of applications and services in an environment with frequent HOs, a Fast Inter-Base Station Ring (FIBR) architecture is described, in which base stations that are in close proximity are grouped together, interconnected by a bidirectional counter-rotating buffer insertion ring network.
