2.2 vSTP Features

The following vSTP features are implemented in release 9.3.0.0.0:

• vSTP HLRR (Home Location Register Router) support with SDS DB:The HLR (Home Location Register) router feature in vSTP (Virtual Signal Transfer Point) retrieves information from the SDS (Subscriber Data Server) and uses them to route messages to HLRs. This feature is a G‑Flex enhancement enabling per‑subscriber routing (MSISDN (Mobile Station International Subscriber Directory Number) or IMSI (International Mobile Subscriber Identity)) to the correct HLR network entity, improving load balancing vs fixed number ranges. For more information, see Oracle Communications vSTP Mobile Number Portability User Guide, and Oracle Communications Subscriber Database Server Provisioning Interface User Guide.
• MTP Origin-Based Routing (MOBR): MTP origin based routing provides customers with greater flexibility and control over the vSTP routing mechanisms by enabling network operators to selectively route traffic to the same destination through different networks, depending on various classes and exception routes.
