Various exemplary embodiments relate to a method, network node, and non-transitory machine-readable storage medium including one or more of the following: identifying a location associated with a user equipment device (UE) in communication with an ANDSF server via an S14 session established over a first access network; retrieving a policy rule that includes a first portion and a second portion; determining, based on evaluating the first portion using the location associated with the UE, that the policy rule is applicable to the S14 session; generating, in response to determining that the policy rule is applicable to the S14 session, a policy based on the second portion, wherein the policy includes an identification of an access point for use by the UE to access a second access network; and transmitting the policy including the identification of the access point to the UE via the S14 session over the first access network.

Rule-driven policy creation by an ANDSF server

Various exemplary embodiments relate to a method performed by a policy and charging rules node (PCRN), the method including: receiving a RADIUS accounting request (ACR) start message from a network access server (NAS); establishing a RADIUS session with the NAS; applying rules by a rules engine to information in the ACR start message to determine a traffic detection function (TDF) to be updated; establishing a Sd session with the TDF; and binding the Sd session to the RADIUS session.

Binding of SD messages with radius messages

Various exemplary embodiments relate to a method performed by a policy and charging rules node (PCRN), the method including: sending a first Sy spending limit request (SLR) to an online charging system (OCS) without specifying any policy counters; receiving from the OCS a first spending limit answer (SLA) including policy counters and associated status reports for a subscriber; creating an Sy session; determining required policy counters based upon the policy counter statuses; sending a second Sy SLR to the OCS for the required policy counters; and receiving a second SLA including status reports for the required policy counters.

Sy session creation and recovering from inconsistent session state between PCRF and OCS

Embodiments of the invention provide an improved major release negotiation mechanism between an initiating node and a receiving node during Diameter session establishment in a 3GPP network.

Multiple major version signaling on session initiation

Various exemplary embodiments relate to a method and related network node including one or more of the following: selecting a connection of a plurality of connections; testing the selected connection to determine whether the selected connection is usable; and based on a determination that the selected connection is not usable: closing the selected connection and at least one additional connection of the plurality of connections, and reestablishing the selected connection and the at least one additional connection.
