Abstract: A method of exchanging a rules engine decision tree cache is disclosed. The method provides for provision accepting a command to build a replacement rules engine decision tree cache, replacing the existing cache if the decision tree creation process is successful, retaining the existing cache if the decision tree creation process is not successful, and providing specific error messages in the event that the replacement fails. The method allows an network operator to change the rules for the rule engine without disruption of real-time service and allows for a level of error checking prior to provisioning the new decision tree.

The method may include: receiving a gateway control session establishment request from a first gateway, the establishment request indicating a first session linking status; establishing a gateway control session between the gateway and the PCRN; receiving a second message from the first gateway for the established gateway control session including a Session-Linking-Indicator AVP indicating a second session linking status; determining whether the PCRN has linked the gateway control session to an IP-CAN session; if the PCRN has not linked the gateway control session to an IP-CAN session, replacing the first session linking status with the second session linking status for the established gateway control session; and linking the gateway control session with an IP-CAN session according to the second session linking status.

Abstract: An electronic component tester characterizes electronic components such as magnetic head/media components measure performance parameters such as signal-to-noise ratio and overwrite evaluation. The electronic component tester has a tester process controller and a spectrum analyzer. The tester process controller generates calibration and control signals for the electronic component tester. The spectrum analyzer is in communication with electronic components such as magnetic head or media components to receive a response characterization signal resulting from a stimulus signal applied to the electronic components. The spectrum analyzer then determines a frequency spectrum of the response characterization signal. The spectrum analyzer is also in communication with the tester process controller for transferring the frequency spectrum to the tester process controller.

Abstract: Embodiments are disclosed that enable a device such as a policy and charging rules function (PCRF) node to operate with other nodes in a long term evolution (LTE) network that are operating at different respective major-minor release combinations of the 3rd Generation Partnership Project (3GPP) standards. Some embodiments enable such a device to operate with another node at a given major-minor release combination of the 3GPP standards with respect to an existing session being managed by the device and at another major-minor release combination of the 3GPP standards when a new session is established by the device. Advantageously, such embodiments mitigate the risk of adversely affecting the existing session after a minor release upgrade of the node associated with the session is performed.

Abstract: Various exemplary embodiments relate to a method performed by a Policy and Charging Rules Node (PCRN) for managing communications sessions. The method may include: determining that a session is suspect of being inactive; sending an innocuous message to a network component that initiated the session; waiting for a response from the network component; if the PCRN receives a response from the network component, determining whether the session is inactive based on the response; and taking at least one management action for the session if the session is inactive. Various exemplary embodiments relate to a PCRN for managing communications sessions. The PCRN may include: one or more interfaces that communicate with network components, one or more PCRN blades that manage communications sessions, and a diameter proxy agent that determines which blade manages a session. Each PCRN blade may include a session manager, a timer and a session data storage.

Abstract: A method for operating a head testing apparatus or, more generally, a host hard disk drive using a mounted hard disk that has had its servo track information pre-written in an external servo-writing apparatus rather than in the head testing or host apparatus itself. The method eliminates repeatable errors and repeatable runout by effectively replacing the pre-written servo tracks, which are eccentric, with new track profiles that are tracked like circular tracks. The problem of repeatable errors is caused by repeatable runout superimposed upon written-in position errors when a disk written in one machine is transferred to another. This problem is eliminated by forming IRON (Iterative Repeatable Runout Nulling) profile tracks from the initially pre-written servo tracks, where the IRON profile tracks are effectively tracked as concentric circular tracks and generate no PES.

Abstract: A method for operating a head testing apparatus (spin stand) using a mounted hard disk that has had its servo track information pre-written in an external servo-writing apparatus rather than in the testing apparatus itself. This insures more accurate servo-track writing and renders the testing operation more efficient. The problem of repeatable runout (RRO) associated with the transfer of a disk written in one machine to another is eliminated by forming a corrected position error signal (PES) by subtracting the average offset of one or more servo sector locations previously calculated using limited bandwidth operation of the servomechanism, from the position error signal generated during full bandwidth servo operation of the apparatus.
