  • Patent number: 7661094
    Abstract: Techniques for tracing the real-time operation of software for the purposes of testing, debugging, or performance analysis are disclosed. Diagnostic instrumentation for generating records containing details of software operation is incorporated in the software by inserting calls to diverse macros or inline functions. Each macro takes an argument specifying both a subsystem and a category of instrumentation within the subsystem. Based on the specified subsystem and category, the instrumentation can be included or excluded from the compiled object code and, if included, can be dynamically enabled at run-time. Disabled instrumentation does not result in a function call, but only a single, inline “if,” thereby reducing overhead. One macro accepts both software parameters and a custom format specifier describing how the parameters should be displayed. However, the parameters are not formatted during logging, nor is the format specifier included in the record. Instead, the formatting is performed when displayed.

  • Patent number: 6915123
    Abstract: A system and method for monitoring the operational area of one or more subscriber stations in a wireless system facilitates determining whether subscriber stations are operating in their authorized coverage areas or not. The system and method first defines a characteristic composite fingerprint for a subscriber station associated with the operation of a subscriber station in an authorized coverage area. An operational area monitor monitors an operational composite fingerprint for the subscriber station. The monitor or another network element compares the operational composite fingerprint to the characteristic composite fingerprint to determine if the subscriber station is operating within the authorized coverage area or the restricted coverage area.

  • Patent number: 6574770
    Abstract: In the method, each transmitting endpoint separates its traffic to be transmitted into distinct queues. The packet at the head of one queue is transmitted, and no other packet is transmitted until a transmit complete signal (TCS) is generated. When a packet is received without error and accepted by a destination endpoint, the destination endpoint returns an acknowledgment indicating successful reception. The TCS is generated at the transmitting endpoint when the receiver acknowledgment should have been received. When the TCS is processed by the transmitting endpoint, if a receiver acknowledgment has been received, the packet previously sent is removed from the head of its queue. Otherwise, the packet is left at the head of its queue, the queue is placed in a “pending retry” state, and a timer is started. When the timer expires, queues are moved out of the “pending retry” state, enabling their packets to be transmitted again.

  • Patent number: 6515977
    Abstract: A technique for de-assigning signals from the fingers of a rake receiver is disclosed. In general, embodiments of the present invention place more stringent standards on signals that have been newly assigned to a finger and may be spurious and place less stringent standards on mature signals that have proved themselves over time but may be experiencing only a temporary signal quality shortfall. Illustrative embodiments of the present invention accomplish this goal using one or more of four techniques. The first technique de-assigns a signal from a finger when a measure of signal quality of the signal crosses a threshold, while changing the threshold as a function of the duration that the signal has been assigned to the finger.

  • Patent number: 6314532
    Abstract: A method and system recover from a failure of an operational software program. A second software program which is known to function properly and is capable of downloading an updated copy of operational software is stored on the computer with the first software program. The second software program is a boot program which monitors resets of the first software program, determines if the number of resets which have occurred without the operational software first having reached a set operating point (such as establishing communication with a remote computer) reaches a threshold, and preempts operation of the first software program when the threshold is reached.

  • Patent number: 6072807
    Abstract: A technique for searching for signals to assign to the fingers of a rake receiver is disclosed. In particular, some embodiments of the present invention identify signals with some PN sequence offsets as more likely to have signals appear at them than other offsets, and monitor the more promising offsets more closely than the less promising offsets, thus enabling signals to be more quickly discovered and assigned to a finger. One embodiment of the present invention comprises: assigning a signal to a finger of a rake receiver; de-assigning the signal from the finger; searching for the signal with the finger after the signal has been de-assigned from the finger; and re-assigning the signal to the finger, if a measure of signal quality of the signal crosses a threshold.
