Abstract
Various exemplary embodiments relate to a method of determining by a network node whether a session establishment request is for a subscriber of a home network. The method may include: defining a home network identity including a network identifier and an emergency access point name (APN); receiving a session establishment request; comparing a called station ID of the session establishment request with the emergency APN; comparing a subscription ID of the session establishment request with the network identifier; and if either the called station ID matches an emergency APN or the subscription ID matches a network identifier: determining that the subscriber is a subscriber of the home network, and fulfilling the session establishment request. Various exemplary embodiments relate to a system for determining the home network of a subscriber. The system may include a policy and charging rules node (PCRN) configured to process a session establishment request.
