In a method and system, one or more communication devices within a communication network are provided with a dynamically and remotely configurable probe element, implemented at least partially in software and controllable by the network operator via one or more communication links, capable of monitoring, measuring and capturing user interaction data flowing from voice and/or data transactions occurring in the network. User interaction data reflects a user's experience on the network and thus provides valuable raw data usable by the network operator for improving network quality from the user's perspective, especially when received from a statistically significant number of network user devices. Collected user interaction data can include network engineering metric data and/or user profile data.

A system and method are provided that use mobile collectors for accessing a wireless sensor network. In certain embodiments, one or more mobile collectors having mobility that is unpredictable to a wireless sensor network are deployed for use in accessing the wireless sensor network. Thus, rather than relying on an access technique having certainty designed therein with regard to the access of a wireless sensor network, certain embodiments utilize an access technique that relies on statistical probability for accessing the wireless sensor network. For instance, by deploying a plurality of mobile collectors that are operable for accessing a wireless sensor network, a statistical probability exists that at some point (or at various points in time) at least one of the mobile collectors will travel within range of the wireless sensor network to enable access thereof.

There are disclosed systems and methods for performing diagnostic testing on portable communication devices, such as cellular telephones. In one embodiment, diagnostic commands are generated internal to the communication device and processed within the device as though the test commands had been received from a remote location. The processed commands can be analyzed either within the portable device or remote therefrom. For remote processing, a wireless port is provided.

A system and method of verifying metadata in a measurement processing system is described. Each combination of metadata is associated with a key, and the keys are used to verify that operations performed using the measurements are valid based on the metadata of the respective measurements. Embodiments allow metadata verification to be made prior to operating on measurements. Embodiments also minimize the processing that results from making such checks redundantly causing slowdown in the measurement processing.

A radiation hardened master latch for use in a programmable phase frequency divider operating at GHz frequencies is implemented in deep submicron CMOS technology, and consists of two identical half circuits interconnected in a DICE-type configuration that makes the master latch immune to a single event upset (SEU) affecting at most one of its four data inputs. Each half circuit includes a clock input circuit with four sub-clock nodes each coupled by an inverter to a common clock input. The clock input circuit is configured to be redundant, such that the operation of the master latch half circuit is also immune to an SEU affecting at most one the inverters associated with the plurality of sub-clock nodes. The radiation hardened master latch resides in a design structure embodied in a machine readable medium storing information for designing, manufacturing and/or testing the master latch.

Aggregate processing of information during network transmission. Information requests are redirected to cause the information to be returned to a processing node where processing takes place before the processed information is returned to the requester. Redirection for processing may be initiated by the requester, or may be initiated on behalf of the requester. Processing nodes may be distributed. Processing requests may be nested so that after a first processing action takes place on data flowing through the network, a second processing action takes place.

Reduced power consumption in a receiver. Power consumption is reduced in a receiver by operating portions of the receiver such as the first RF amplifier, local oscillator, and associated phase locked loop at reduced power in a standby mode, trading lower power for lower performance. In a normal operating mode, these portions of the receiver operate at full power and performance.

Coding numeric values into text. Uncertainty metadata kept with stored values is used to facilitate numeric-to-text conversion. Using uncertainty associated with values, only meaningful mantissa digits are returned. Excess information is trimmed to reduce transmission times.
