Abstract: Methods, systems, and computer readable media for charging based on radio congestion in mobile networks are disclosed. In some examples, a method includes receiving a radio congestion message specifying a user plane congestion level for a radio access network (RAN) from a RAN congestion awareness function (RCAF) for the RAN. The method includes providing the user plane congestion level to a charging system. The method includes, at the charging system, altering one or more charging records for one or more respective subscribers accessing the RAN with user equipment (UE) based on the user plane congestion level.

Abstract: A method includes establishing, by a machine type communication (MTC) accumulator, a first direct communication path tunnel with a eNodeB and a second direct communication path tunnel with a MTC application server (AS), receiving, by the eNodeB, radio resource control (RRC) packet containing MTC data as a payload from a MTC UE device over an established radio bearer link, and locating, by the eNodeB, a MTC data forwarding indicator included in the RRC packet. In response to locating the MTC data forwarding indicator included in the RRC packet, forwarding the MTC Data to the MTC accumulator and facilitating, by the MTC accumulator, a MTC communication session between the MTC UE device and the MTC application server identified by a MTC application server identifier contained in the MTC data over the established first and second direct communication paths.

Abstract: Methods, systems, and computer readable media for dynamically provisioning subscriber based session timeout information are disclosed. One method includes method includes receiving, from a packet data network gateway (PGW), a request message containing session information parameters corresponding to a session requested by a user equipment device and deriving an absolute timeout period value and an idle timeout period value based on input comprising one or more of the session information parameters. The method further includes generating a response message containing the determined absolute timeout period value and the determined idle timeout period value and sending the generated response message to the PGW, wherein the PGW is configured to apply the absolute timeout period value and the idle timeout period value to the session requested by the user equipment device.

Abstract: Methods, systems, and computer readable media for sharing identification information of network nodes in an IMS network are disclosed. One method includes determining, by a packet data network gateway (PGW), policy and charging rules function (PCRF) identification information corresponding to a PCRF node designated to support an IMS-based subscriber session requested by a user equipment device and establishing, by the PGW, a subscriber Gx session with the PCRF node corresponding to the determined PCRF identification information. The method further includes determining, by the PGW, application function (AF) identification information corresponding to an AF server designated to support the IMS-based subscriber session and generating, by the PGW, a create session response message including at least the PCRF identification information and the AF identification information. The method also includes sending, by the PGW, the create session response message containing the at least the PCRF identification inform.

Abstract: Methods, systems, and computer readable media for validating a redirect address in a Diameter message are disclosed. One method occurs at a Diameter node, e.g., a Diameter routing agent (DRA) node, a packet data network (PDN) gateway, a policy and charging enforcement function (PCEF) node, or a Diameter edge agent (DEA) node. The method includes receiving a message containing a redirect address that appears to be associated with a top-up server for facilitating a subscriber to recharge or top-up an account balance. The method also includes determining whether the redirect address is valid by querying, using a subscriber related identifier, a data structure containing one or more addresses. The method further includes performing at least one action based on the determining.

Abstract: Methods, systems, and computer readable media for priority routing of Diameter messages are disclosed. In some examples, a method includes determining a Diameter Routing Message Priority (DRMP) priority value for a Diameter message. The method includes marking each of one or more Internet protocol (IP) packets carrying the Diameter message with an IP quality of service (QoS) value for the Diameter message based on the DRMP priority value. The method includes sending the one or more IP packets carrying the Diameter message to a destination Diameter node by way of an IP router on a data communications network providing quality of service using IP QoS values.
