The method may include: defining a roaming partner profile including a network identifier and a primary realm; receiving a session establishment request at the PCRN; extracting a subscription identifier from the session establishment request; determining an active roaming partner by comparing the subscription identifier to the network identifier; and establishing an S9 session with the primary realm of the active roaming partner. Another method may include: defining a roaming partner profile including a primary realm and at least one secondary realm; receiving an S9 session establishment request; extracting an origin realm from the S9 session establishment request; determining an active roaming partner by comparing the origin realm to the primary realm and the secondary realms of the roaming partner profile; and responding to the S9 session establishment request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Organization of roaming partner realms into primary and secondary","description":"Various exemplary embodiments relate to a method performed by a policy and charging rules node (PCRN) of communicating with a roaming partner.
