20110276667 | PCRF TRIGGERED RULES CLEANUP - Various embodiments relate to a system and related method of handling a plurality of user messages originating from a user device in a communications network. Various embodiments relate to a Policy Charging and Rules Node (PCRN) receiving an initial message from a first device, while anticipating a complementary message from a second device. Upon receipt of the complementary message, the PCRN may pair the messages and generate a rule from the paired message. If the PCRN does not receive the complementary message, the PCRN may generate the rule from only the initially-received message or may ignore the message. The PCRN may treat each received message independent from each other so that lack of receipt of a complementary message does not affect the creation of rules from another paired message. | 11-10-2011 |
20110281554 | EXTENSIBLE DATA DRIVEN MESSAGE VALIDATION - Various exemplary embodiments relate to a method, network component and machine-readable storage medium for validating a message received at a network component. Embodiments may include one or more of the following: receiving a message at the network component, determining a validation scenario, determining a set of validation conditions associated with the determined validation scenario, and determining whether the message passes the validation condition. Various exemplary embodiments may further include extensible condition definitions that include one or more of the following: validation fragments, element validation definitions, and element definitions. Various exemplary embodiments may use XML to define condition definitions. | 11-17-2011 |
20110295935 | MINIMIZING PCC RULE INSTANTIATION LATENCY - Various exemplary embodiments relate to a method, policy and charging rules node (PCRN) and machine-readable storage medium for creating policy and control charging rules with minimal rule instantiation latency. Embodiments may include one or more of the following: receiving at a PCRN from an application node a first service request message, determining whether the PCRN should wait for a mate message for the service flow, if the PCRN should not wait for a mate message, immediately generating at least one PCC rule, and immediately pushing the first PCC rule to at least one gateway. Various exemplary embodiments may further include using subscriber preferences and/or a record of previous decisions to determine whether the PCRN should wait for a mage message. In various embodiments, the PCRN may disable a timer when it determines it should not wait for a mate message. | 12-01-2011 |
