When performing load balancing in a wireless extended self-organizing network (extended SON), network health status is monitored by collecting network measurement data and identifying network nodes that require policy adjustment. Based on the network measurement data, network and/or user policies are automatically adjusted and policy updates are disseminated by a policy and charging rule function module to a packet gateway (PGW) as well as to one or more non-PGW network nodes (e.g., base stations, mobility management entity (MME) nodes, radio network controller (RNC) nodes, and the like). The automated policy updates are locally enforced at the nodes that receive the updates, rather than solely at the PGW node.

The invention provides a method, system, network elements and computer programs, for providing service control. A Policy and Charging Rules Function, PCRF, sends rules for service control not only to a gateway but also to another network element such as a home agent, upon request, e.g. when a user equipment is registering to the network. The home agent preferably is a home agent of a Mobile Internet Protocol, IP, network.

A system for congestion control in a mobile communications network includes a monitoring module configured to monitor message traffic associated with a cell in a mobile communications network. The message traffic includes control plane and user plane messages. The monitoring module determines, based on the message traffic, whether a predetermined congestion threshold associated with the cell in the mobile communications network has been crossed. In response to the threshold being crossed, the monitoring module generates a cell congestion notification message that includes the identity of subscribers that are contributing to the congestion. A policy server receives the cell congestion notification message and generates a PCC rule that modifies the policy of the one or more identified subscribers and for communicating the PCC rule to a PCEF.

A method for selecting a policy and charging rules function. When a UE accesses a 3GPP system through a roaming architecture, upon receiving a session establishment request message sent by a PCC client located in the visited network, the DRA in the visited network forwards the message to a selected PCRF of the visited network according to the records stored locally or instructs the PCC client to transmit the session establishment request message to the selected PCRF of the visited network; and the PCRF of the visited network forwards the session establishment request message to a DRA of a home network, then the DRA of the home network forwards the message to the selected PCRF of the home network according to the records stored locally or instructs the PCRF of the visited network to transmit the session establishment request message to the selected PCRF of the home network.

Conventional quality of service (QoS) treatment is extended to over-the-top (OTT) applications transmitting data over a commercial wireless network via a virtual private network (VPN) tunnel. An over-the-top (OTT) application server and a VPN client/server routing data to/from that OTT application server via a VPN tunnel, are integrated with a quality of service (QoS) server to enable the OTT application server and/or VPN client/server to request and get desired QoS treatment for application data routed by the OTT application server over the VPN tunnel. The QoS server forwards QoS rules received in a QoS request message to a policy and charging rules function (PCRF) on the OTT application/VPN client devices' home mobile network operator (MNO). If the client device is roaming, the PCRF on the home MNO forwards QoS rules to a PCRF on a serving MNO. QoS treatment is then carried out by the PCRF in a conventional manner.

The invention discloses a method for realizing policy and charging control, which comprises the following steps: after the Policy and Charging Rules Function (PCRF) receives policy rules request message transmitted by the Policy and Charging Enforcement Function (PCEF), comparing the acquired traffic flow of a user with the cumulative flow, determining the Policy and Charging Control (PCC) rules based on the comparison result according to the locally configured or the acquired traffic control policy. The PCRF performs the PCC rules decision based on the acquired traffic flow of the user, the cumulative flow and the flow control policy, and delivers the PCC rules to the PCEF to execute. Moreover, the PCEF reports to the PCRF when the traffic flow of user reaches to a threshold, the PCRF re-performs the PCC rules decision and delivers the PCC rules to the PCEF to execute, so as to achieve the policy and charging control based on the traffic flow of the user.

Fine grained RAN aware traffic prioritization in spectrum constrained modern wireless networks which support differentiated service plans uses cell load metrics supplied to a Fine grained Traffic flow Prioritization Engine (FTPE) with and without the assistance from a client side collection module, Peer Agent (PA), at the mobile. Knowledge about a mobile's subscription plan is derived from a Subscription Profiles Repository (SPR). Dynamic control on traffic prioritization is applied through operator policy control engines, Policy and Charging Rules Function (PCRF) module.

The FPTE may apply Deep Packet Inspection (DPI) techniques to identify application flows, and uses hierarchical queue disciplines to achieve the necessary flow control. The FPTE may also instead use an adjunct DPI to perform the flow identifications.
