IMS-AKA and TLS Support

The Oracle Communications Subscriber-Aware Load Balancer (SLB) supports IMS-AKA and TLS traffic, forwarding it to and from the Session Border Controllers (SBCs) within IP-over-IP tunnels. Both IPv4 and IPv6 are supported.

IMS-AKA and TLS traffic support requires configuration on the SLB and the OCSBC:

  • For IMS-AKA:
    • The SLB requires a service-port configured with port 0 and protocol ALL.
    • The OCSBC requires a dedicated range of client ports and a dedicated server port configured in the IMS-AKA config to accommodate encrypted traffic.
  • For TLS:
    • The SLB requires the applicable service-port configured with either:
      • The applicable service-port configured with the protocol value of ALL and the port configured with 0, or
      • The applicable service-port configured with the protocol value of TCP and the port configured with the correct number.
    • The OCSBC requires normal TLS configuration, as described in the ACLI Configuration Guide.
