  • Patent number: 9495706
    Abstract: Various exemplary embodiments relate to a method for managing subscriber usage in a mobile network by a policy and charging rules function (PCRF) including: receiving a credit control request (CCR) message from a policy and enforcement rules function (PCEF) for an application; determining if a Sy connection to an online charging system (OCS) is necessary to implement the CCR; determining if a Sy session is present; sending an application authorization request (AAR) message to the OCS; binding a counter to the application; determining a policy to apply based upon the application; and sending a credit control answer (CCA) message to the PCEF to effect the policy.

  • Patent number: 9392534
    Abstract: Various exemplary embodiments relate to a method, network node, and non-transitory machine-readable storage medium including one or more of the following: identifying, by an ANDSF server, a location associated with a UE in communication with the ANDSF server via an S14 session over a first access network; determining a plurality of access points for use by the UE to utilize at least one access network other than the first access network; calculating a first score for a first access point; calculating a second score for a second access point; generating a policy identifying the first access point associated with a first priority and the second access point associated with a second priority, wherein the first priority is set higher than the second priority based on a comparison of the first score to the second score; and transmitting the policy to the UE.

  • Patent number: 9277014
    Abstract: Various exemplary embodiments relate to a method and related network node including: receiving, at the network device, a traffic message including an IP address; identifying the traffic message as belonging to a new session; generating a request message based on identifying the traffic message as belonging to a new session, wherein the request message includes the IP address; transmitting the request message to a policy server; and receiving, from the policy server, a policy message including a policy. Various exemplary embodiments relate to a method and related network node including: receiving, at the policy server, a request message from a network device, the request message including a subscriber IP and a network device identifier; identifying a subscriber session associated with the IP address; recording the network device identifier in association with the subscriber session; retrieving a policy associated with the subscriber session; and transmitting the policy to the network device.

  • Patent number: 9276863
    Abstract: Various exemplary embodiments relate to a method performed by a policy manager network node in a network, the method including: receiving accounting threshold information relating to an access session associated with an access node; receiving accounting network usage measurement message relating to the access session; determining that a total network usage of the access session exceeds a threshold; and sending a change of authorization message to the access node, wherein the change of authorization message limits a first type of network access, redirects a user of the access node, and allows a second type of network access to continue.

  • Patent number: 9131071
    Abstract: 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.

  • Patent number: 8498286
    Abstract: A method and apparatus are provided for allowing a single platform to recognize and process both Diameter messages and Radius messages. A gateway is provided for translating Radius messages received from a wireline device into NASReq messages. A Diameter Proxy Agent receives both Diameter messages from a wireless device and the NASReq messages from the gateway. The Diameter Proxy Agent selects a PCRF to which to pass a NASReq message, and upon receipt of a NASReq message the PCRF either creates or updates a NASReq session object. By recognizing and processing Radius messages, wireline services can be offered at the same time as wireless services without requiring the use of a second platform. In addition, use of the PCRF server to support wireline services offers much better scalability than that offered by traditional AAA servers.
