According to one aspect, the subject matter described herein includes a method for determining condition-triggered policies. The method occurs at a Diameter node. The method includes receiving a notification of a network condition. The method further includes determining, based on the network condition, policy information for a plurality of associated subscribers.

Methods, systems, and computer readable media for condition-triggered policies

Methods, systems, and computer readable media for steering a subscriber between access networks are disclosed. According to one aspect, a method for steering a subscriber between access networks includes, at a first policy and charging rules function (PCRF) that serves a first access network, identifying a subscriber of the first access network as a candidate for steering to a second access network that is served by a second PCRF, querying the second PCRF to determine whether the candidate subscriber is allowed access to the second access network, and, upon a determination that the candidate subscriber is allowed access to the second access network, steering the candidate subscriber to the second access network.

A set of forwarding elements act as a gateway to a data network for a subscriber end station. A controller network element includes a control plane operable to communicate with the forwarding elements, which are operable to communicate with the subscriber end station. The controller network element includes a quota management module, which determines a quota amount to be assigned to the forwarding elements for a traffic flow. The quota management module assigns portions of the quota amount to the forwarding elements. The quota management module determines to change the distribution of an unconsumed quota amount amongst the forwarding elements for the traffic flow, determine the unconsumed quota amount, and determine and assign portions of the unconsumed quota amount to the forwarding elements.

Embodiments of the present invention provide a method for processing a rate group, a method for charging for a data service, and a related device and system, so as to enable a charging system to accurately charge for the data service when the rate group changes. The method includes: determining, by a gateway device, whether a rate group of a service data stream changes; and if the rate group of the service data stream changes, reporting, by the gateway device, charging data to the charging system, so that the charging system performs charging according to the charging data, where the charging data includes service usage information and a reporting reason for reporting the charging data, and the reporting reason indicates a change of the rate group.

Communication networks and methods are disclosed for performing online charging in LTE/EPC communication networks. In an LTE/EPC communication network, one or more LTE network elements connect to an Online Charging System (OCS) over an enhanced interface. The LTE network element that is serving a session for a mobile device triggers on a charging event, and generates a credit request message (e.g., Diameter CCR). The LTE network element identifies access information for the session indicating the type of access for the mobile device to the LTE/EPC communication network, and inserts the access information in the credit request message. Through the enhanced interface, the LTE network element is able to transmit the credit request message to the OCS with the access information. The access information may then be used in the OCS to determine a more accurate charging rate for the session.
