Abstract: A pattern implementation technique in which a pattern is defined as a software artifact that comprises a pattern signature representing one or more parameters of the pattern and a pattern implementation model representing one or more methods for expanding the pattern in a selected software context by assigning one or more arguments to the one or more parameters. The pattern implementation model can be based on one or more framework code sets, each of which supports the creation of plural patterns by providing a pattern implementation model for a particular software context. The framework code sets can be rendered extensible by a pattern author by virtue of providing methods whose code is adapted to be modified by a pattern author when defining a pattern. The pattern can be applied by creating an instance of the pattern in a software context and presenting a graphical representation of the pattern instance that can be manipulated by the pattern user in order to apply arguments to the pattern parameters.

Abstract: A method for determining the location of a mobile unit (MU) in a wireless communication system and presenting it to a remote party. The location of a remote MU is determined by comparing a snapshot of a predefined portion of the radio-frequency (RF) spectrum taken by the MU to a reference database containing multiple snapshots taken at various locations. The result of the comparison is used to determine if the MU is at a specific location. The comparison may be made in the MU, or at some other location situated remotely from the MU. In the latter case, sufficient information regarding the captured fingerprint is transmitted from the MU to the remote location. The database may be pre-compiled or generated on-line.

Abstract: It is desired to test network management applications, for example, to show that they will work with large or very large networks, to determine the upper bounds of the applications capabilities, and to determine improvements which might, for example, increase the upper bounds. A method of testing a network application is disclosed providing a mapping of the layer-3 addresses of a real subnetwork onto a plurality of mapped layer-3 subnetwork addresses for conversations with the application or device. A packet is modified to change a destination layer-3 address in a mapped subnetwork, to point to the corresponding real IP address and the packet is forwarded on. The conversation to which a response from a reallayer-3 address relates is identified. The source layer-3 address and packet contents are changed into the appropriate mapped subnetwork and the packet is forwarded to the application or device.

Abstract: A method of estimating the location of a wireless terminal is disclosed. The illustrative embodiment of the present invention is based on the observation that the signal strength of a signal from a transmitter is different at some locations, and, therefore, the location of a wireless terminal can be estimated by comparing the signal strength it currently observes against a map or database that correlates locations to signal strengths. Furthermore, the illustrative embodiment deduces the signal strength of one or more base stations' control channels at the wireless terminal based on the principal of reciprocity, whether or not the wireless terminal can actually receive the base stations' control channels but so long as the base station can receive and measure the uplink signal from the wireless terminal. The deduced signal-strength measurements can then used—alone or in combination with the empirical signal-strength measurements—to estimate the location of the wireless terminal.

The illustrative embodiment provides a computationally-efficient technique for reducing the number of possible positions that have to be analyzed. In particular, the illustrative embodiment eliminates possible positions for the mobile unit from consideration by considering which signals the mobile unit can—and cannot—receive and the knowledge of where those signals can and cannot be received.

Abstract: A method and apparatus for estimating the location of a wireless terminal are disclosed. The location of the wireless terminal is estimated based on one or more signal strength measurements in conjunction with: (i) one or more angle-of-arrival measurements, (ii) one or more time-of-arrival measurements, or (iii) a combination of (i) and (ii). At each measurement time, the illustrative embodiment (a) determines the candidate locations for the wireless terminal, (b) computes a measurement likelihood function for any signal strength measurements that are available at that time, (c) computes a measurement likelihood function for any geometry-of-arrival measurements that are available at that time, (d) computes a joint likelihood function for all measurements available at that time, and (e) updates the location probability distribution for the wireless terminal with the joint measurement likelihood function. Estimates of the location of the wireless terminal are obtained from the location probability distribution.

Abstract: Methods and apparatus are disclosed for measuring position and motion of a “marker” antenna (14), disposed on a subject (12) at a physical location to be tracked. Relative distance of the marker antenna (14) from receiving antennas (18) is measured by phase differences of its microwave signals (40) at the receiving antennas (18) for at least two successive marker positions. Alternatively, actual distances (104, 106) are calculated by choosing a source position (102) and iterating the distances (104, 106) until the calculated phase differences match those measured. Four to six receiving antennas (18) are positioned at edges of a volume (16) where activity is conducted. Each received signal (40) is amplified and down-converted in a mixer (44). A single reference oscillator (46) feeds all the mixers (42) to preserve phase relationships of the received signals. Received signals (40) are digitized and presented to a multi-channel digital tuner (50).

Abstract: The present invention enables efficient storage and retrieval of signal-strength measurements and geometry-of-arrival measurements for estimating the location of a wireless terminal. A database is populated with signal-strength measurements and geometry-of-arrival measurements for each of a plurality of locations. Subsequent queries to the database enable rapid retrieval of the signal-strength measurements and geometry-of-arrival measurements, and thus enable a computationally-efficient estimate of the location of a wireless terminal based on these measurements. By supplementing signal-strength measurements with geometry-of-arrival measurements, the illustrative embodiment enables a more accurate estimate of location to be made than could be achieved with either the signal-strength measurements or the geometry-of-arrival measurements alone.

Abstract: A method of estimating the location of a wireless terminal is disclosed that is ideally suited for use with legacy systems. The illustrative embodiment of the present invention is based on the observation that the signal strength of a signal from a transmitter is different at some locations, and, therefore, the location of a wireless terminal can be estimated by comparing the signal strength it currently observes against a map or database that correlates locations to signal strengths. For example, if a particular radio station is known to be received well at a first location and poorly at a second location, and a given wireless terminal at an unknown location is receiving the radio station poorly, it is more likely that the wireless terminal is at the second location than it is at the first location.
