Session Type Conflict Resolution at cnSGW

cnSGW resolves a session type conflicts by tagging:

  • A session as emergency, if the DNN is tagged to emergency or if the session created is an emergency session. For emergency session, cnSGW uses the QCI/ARP received in the CS request to select a Message Priority.

  • A session as IMS/VOLTE, when a bearer gets created with the QCI configured as IMS/VOLTE under DNN profile.

  • A session as WPS based on QCI/ARP received.

  • If a session satisfies multiple condition, session type is tagged based on the following criteria:

    WPS > Emergency > IMS
