20110320584 | METHOD FOR DETERMINING A PCC RULE WAITING FOR PCEF ACTION - Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, at a policy and charging rules node from a first requesting device, a first message including a first set of information regarding an application request; generating a set of PCC rules for fulfilling the application request based on the first set of information; determining whether the PCRN should wait for a period of time for at least one PCC rule to receive a second message including a second set of information regarding the application request; and if the PCRN should wait for the period of time: waiting for the period of time to receive a second message including a second set of information regarding the application request, determining, after the time has elapsed, whether the second message has arrived, and if the second message has not arrived, initiating a cleanup procedure. | 12-29-2011 |
20110320620 | METHOD OF AUTHORIZING AF SESSIONS USING EXTERNAL SUBSCRIBER DATABASE - Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, at the policy and charging rules node from a requesting entity, a message including a request associated with at least one service data flow (SDF), wherein the request includes at least one requested bandwidth; extracting at least one subscriber identifier from the message; retrieving a subscription record associated with the at least one subscriber identifier; determining whether the request should be fulfilled by performing at least one comparison of the at least one requested bandwidth for the SDF against at least one field of the subscription record; if the request should be fulfilled, establishing the SDF; and if the request should not be fulfilled: generating a response message that indicates that the request was rejected, and transmitting the response message to the requesting entity. | 12-29-2011 |
20120005358 | RETURN OF MULTIPLE RESULTS IN RULE GENERATION - Various embodiments relate to a Policy Charging and Rules Node (PCRN) and a related method and machine-readable medium for retrieving multiple results in response to a message. The PCRN may receive a message and, through handling the received message, may make a policy decision. The policy decision may require the PCRN to retrieve multiple related results. The PCRN may thereafter refer to a data arrangement that includes a rule set with at least one rule with multiple values. Based on the policy decision, the PCRN may retrieve the at least one rule. The PCRN may compile the rule from the rule set and may generate an answer message including at least one of these values included in the rule. | 01-05-2012 |
