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.

PCRN home network identity

Various exemplary embodiments relate to a method performed by a policy and charging rules node (PCRN) for processing a change in a status of a roaming partner, the method including: receiving, at the PCRN, a message indicating a change in a status of the roaming partner; identifying roaming subscriber sessions associated with the roaming partner; determining home based roaming subscriber sessions among the identified subscriber sessions; marking the determined home based roaming subscriber sessions for termination; and sending a termination message to a policy and charging enforcement node for the determined home based roaming subscriber sessions.

Roaming session termination triggered by roaming agreement/partner deletion

Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, at the network device, a message; determining, in response to receiving the message, that a set of supported features should be transmitted to a partner device; determining, based on the partner device, whether a default set of features should be overridden; if the default set of supported features should be overridden, transmitting an alternative set of features to the partner device; and if the default set of supported features should not be overridden, transmitting a standard set of features based on the default set of features to the partner device.

Supported feature override

Various exemplary embodiments relate to a method performed by a policy and charging rules node (PCRN) for managing a session for a roaming subscriber. The method may include: defining a roaming agreement associated with at least one roaming partner and including at least one limitation; receiving a session establishment request; extracting a subscription identifier; determining an active roaming partner by comparing the subscription identifier to the roaming partner profile; selecting the roaming agreement including the active roaming partner; and enforcing the at least one limitation when processing the session establishment request. The PCRN may include: a roaming agreement storage; a first interface configured to receive a session establishment request for a roaming subscriber; a roaming manager configured to identify a roaming partner associated with the roaming subscriber and a roaming agreement associated with the roaming partner; and a second interface configured to communicate session information with a roaming partner PCRN.
