`
`stations, wherein the same communication standard or protocol is utilized for location as is used by the
`
`network of base stations for providing wireless communications with mobile stations for other purposes
`
`such as voice communication and/or visual communication (such as text paging, graphical or video
`
`communications). Related objectives for various embodiments of the present invention include providing

`
`determining a wireless location within a building, techniques for determining a mobile station location
`
`using wireless location data collected from the wireless coverage area for, e.g., location techniques using
`
`base station signal coverage areas, signal pattern matching location techniques and/or stochastic
`
`techniques), wherein each such estimator may be activated independently of one another, whenever
`
`suitable data is provided thereto and/or certain conditions, e.g., specific to the estimator are met;
`
`(1.8)
`
`can provide a common interface module from which a plurality of the location estimators can be
`

`
`911 emergency, the fire or police departments, taxi services, vehicle location, etc.) via an output gateway,
`
`wherein this gateway:
`
`(a)
`
`routes the mobile station location estimates to the appropriate location application(s) via
`
`a communications network such as a wireless network, a public switched telephone
`
`network, a short messaging service (SMS), and the Internet,
`
`(b)

`determines the location granularity and representation desired by each location application
`
`requesting a location of a mobile station, and/or
`
`(c)
`
`enhances the received location estimates by, e.g., performing additional processing
`
`such as "snap to street" functions for mobile stations known to reside in a vehicle.
`
`Please replace the paragraph beginning on page 11, line 15 with the following paragraph:
`
`(3.3) The term, "infrastructure", denotes the network of telephony communication services, and more
`
`particularly, that portion of such a network that receives and processes wireless communications with
`
`wireless mobile stations. In particular, this infrastructure includes telephony wireless base stations (BS)
`
`such as those for radio mobile communication systems based on CDMA, AMPS, NAMPS, TDMA, and
`
`GSM wherein the base stations provide a network of cooperative communication channels with an air
`
`interface with the MS, and a conventional telecommunications interface with a Mobile Switch Center
`
`(MSC). Thus, an MS user within an area serviced by the base stations may be provided with wireless
`
`communication throughout the area by user transparent communication transfers (i.e., "handoffs")
`
`between the user's MS and these base stations in order to maintain effective telephony service. The

`
`~ ~~ mobile switch center (MSC) provides communications and control connectivity among base stations and
`~ the public telephone network 124.
`
`Please replace the paragraph beginning on page 12, line 6 with the following paragraphs:
`
`The present invention relates to a wireless mobile station location system, and in particular,
`
`various subsystems related thereto such as a wireless location gateway, and the combining or hybriding of
`
`a plurality of wireless location techniques.
`
`Regarding a wireless location gateway, this term refers to a communications network node
`
`whereat a plurality of location requests are received for locating various mobile stations from various
`
`sources (e.g., for E911 requests, for stolen vehicle location, for tracking of vehicles traveling cross
`
`country, etc.), and for each such request and the corresponding mobile station to be located, this node: (a)
`
`activates one or more wireless location estimators for locating the mobile station, (b) receives one or more
`
`location estimates ofthe mobile station from the location estimators, and (c) transmits a resulting location
`
`estimate(s) to, e.g., an application which made the request. Moreover, such a gateway typically will likely
`
`activate location estimators according to the particulars of each individual wireless location request, e.g.,
`
`the availability of input data needed by particular location estimators. Additionally, such a gateway will
`
`typically have sufficiently well defined uniform interfaces so that such location estimators can be added
`
`and/or deleted to, e.g., provide different location estimators for performing wireless location different
`
`coverage areas.
`
`The present invention encompasses such wireless location gateways. Thus, for locating an
`
`identified mobile station, the location gateway embodiments of the present invention may activate one or.
`
`more of a plurality of location estimators depending on, e.g., (a) the availability of particular types of
`
`wireless location data for locating the mobile station, and (b) the location estimators accessable by the
`
`location gateway. Moreover, a plurality of location estimators may be activated for locating the mobile
`
`station in a single location, or different ones of such location estimators may be activated to locate the
`
`mobile station at different locations. Moreover, the location gateway of the present invention may have
`
`incorporated therein one or more of the location estimators, and/or may access geographically distributed
`
`location estimators via requests through a communications network such as the Internet.
`
`In particular, the location gateway of the present invention may access, in various instances of
`
`locating mobile stations, various location estimators that utilize one or more of the following wireless
`
`location techniques:
`
`(a)
`
`A GPS location technique such as, e.g., one of the GPS location techniques as
`
`described in the Background section hereinabove;

`4 of230
`
`Apple, Inc. Exhibit 1022 Page 5
`
`

`
`Application Serial No.: 091194,36-
`Document: "Preliminary Amendment"
`
`(b)
`
`A technique for computing a mobile station location that is dependent upon
`
`geographical offsets of the mobile station from one or more terrestrial
`
`transceivers (e.g., base stations of a commercial radio service provider). Such
`
`offsets may be determined from signal time delays between such transceivers and
`
`the mobile station, such as by time of arrival (TOA) and/or time difference of
`
`arrival (TDOA) techniques as is discussed further hereinbelow. Moreover, such
`
`offsets may be determined using both the forward and reverse wireless signal
`
`timing measurements of transmissions between the mobile station and such
`
`terrestrial transceivers. Additionally, such offsets may be directional offsets,
`
`wherein a direction is determined from such a transceiver to the mobile station;
`
`(c)
`
`Various wireless signal pattern matching, associative, and/or stochastic
`
`techniques for performing comparisons and/or using a learned association
`
`between:
`
`(i)
`
`characteristics of wireless signals communicated between a mobile
`
`station to be located and a network of wireless transceivers (e.g., base
`
`stations), and
`
`(ii)
`
`previously obtained sets of characteristics of wireless signals (from each
`
`of a plurality of locations), wherein each set was communicated, e.g.,
`
`between a network of transceivers (e.g., the fixed location base stations
`
`of a commercial radio service provider), and, some one of the mobile
`
`stations available for communicating with the network;
`
`Indoor location techniques using a distributed antenna system;
`
`Techniques for locating a mobile station, wherein, e.g., wireless coverage areas
`
`of individual fixed location transceivers (e.g., fixed location base stations) are
`
`utilized for determining the mobile station's location (e.g., intersecting such
`
`coverage areas for determining a location);
`
`Location techniques that use communications from low power, low functionality
`
`base stations (denoted "location base stations"); and
`
`Any other location techniques that may be deemed worthwhile to incorporate into
`
`an embodiment of the present invention.
`
`(d)
`
`(e)
`
`(f)
`
`(g)
`
`Accordingly, some embodiments of the present invention may be viewed as platforms for
`
`integrating wireless location techniques in that wireless location computational models (denoted "first
`
`order models" or "FOMs" hereinbelow) may be added and/or deleted from such embodiments of the
`
`invention without changing the interface to further downstream processes. That is, one aspect of the
`
`5 of230
`
`Apple, Inc. Exhibit 1022 Page 6
`
`

`
`Application Serial No.: 091194,36-
`Document: "Preliminary Amendment"
`
`invention is the specification of a common data interface between such computational models and
`
`subsequent location processing such as processes for combining of location estimates, tracking mobile
`
`stations, and/or outputting location estimates to location requesting applications.
`
`Moreover, it should be noted that the present invention also encompasses various hybrid
`
`approaches to wireless location, wherein various combinations of two or more of the location techniques
`
`(a) through (g) immediately above may be used in locating a mobile station at substantially a single
`
`location. Thus, location information may be obtained from a plurality of the above location techniques
`
`for locating a mobile station, and the output from such techniques can be synergistically used for deriving
`
`therefrom an enhanced location estimate of the mobile station.
`
`It is a further aspect of the present invention that it may be used to wirelessly locate a mobile
`
`station: (a) from which a 911 emergency call is performed, (b) for tracking a mobile station (e.g., a truck
`
`traveling across country), (c) for routing a mobile station, and (d) locating people and/or animals,
`
`including applications for confinement to (and/or exclusion from) certain areas.
`
`It is a further aspect of the present invention that it may be decomposed into: (i) a first low level
`
`wireless signal processing subsystem for receiving, organizing and conditioning low level wireless signal
`
`measurements from a network of base stations cooperatively linked for providing wireless
`
`communications with mobile stations (MSs); and (ii) a second high level signal processing subsystem for
`
`performing high level data processing for providing most likelihood location estimates for mobile
`
`stations.
`
`Please replace the paragraph beginning on page 12, line 11 with the following paragraph:
`
`Thus, the present invention may be considered as a novel signal processor that includes at least
`
`the functionality for the high signal processing subsystem mentioned hereinabove. Accordingly,
`
`assuming an appropriate ensemble of wireless signal measurements characterizing the wireless signal
`
`communications between a particular MS and a networked wireless base station infrastructure have been
`
`received and appropriately filtered of noise and transitory values (such as by an embodiment ofthe low
`
`level signal processing subsystem disclosed in a copending PCT patent application PCT/US97115933
`
`titled, "Wireless Location Using A Plurality of Commercial Network Infrastructures," by F. W. LeBlanc et
`
`al., filed September 8, 1997 from which U.S. Patent 6,236,365, filed July 8, 1999 is the U.S. national
`
`counterpart; these two references being herein fully incorporated by reference), the present invention uses
`
`the output from such a low level signal processing system for determining a most likely location estimate
`
`of an MS.

`Document: ''Preliminary Amendment"
`
`Please replace the paragraph beginning on page 12, line 19 (and ending on this same line 19) with
`
`the following paragraph:
`
`That is, once the following steps are appropriately performed (e.g., by the LeBlanc U.S. Patent
`
`6,236,365):
`
`Please replace the paragraph beginning on page 12, line 28 has been replaced with the following
`
`paragraph:
`
`c
`
`(4.3)
`
`providing the composite s~gnal characteristic values to one or more MS location hypothesizing
`
`computational models (also denoted herein as "first order models" and also "location estimating
`.....
`models"), wherein each such mo·d~l subsequently determines one or more initial estimates of the location
`
`of the target MS based on, fop: example, the signal processing techniques 2.1 through 2.3 above.
`·.,;~.
`Moreover, each of the models olinmt MS location estimates having substantially identical data structures
`
`(each such data structure denoted· a "location hypothesis"). Additionally, each location hypothesis may
`
`also include a confidence value indicating the likelihood or probability that the target MS whose location
`
`is desired resides in a corresponding location estimate for the target MS;
`
`Please replace the paragraph beginning on page 13, line 14 with the following paragraph:
`
`Referring now to (4.3) above, the filtered and aggregated wireless signal characteristic values are
`
`provided to a number oflocation hypothesizing models (denoted First Order Models, or FOMs), each of
`
`which yields a location estimate or location hypothesis related to the location of the target MS. In
`
`particular, there are location hypotheses for both providing estimates of where the target MS is likely to
`
`be and where the target MS is not likely to be. Moreover, it is an aspect of the present invention that
`
`confidence values ofthe location hypotheses are provided as a continuous range of real numbers from,
`
`e.g., -1 to 1, wherein the most unlikely areas for locating the target MS are given a confidence value of -1,
`
`and the most likely areas for locating the target MS are given a confidence value of I. That is, confidence
`
`values that are larger indicate a higher likelihood that the target MS is in the corresponding MS estimated
`
`area, wherein -1 indicates that the target MS is absolutely NOT in the estimated area, 0 indicates a
`
`substantially neutral or unknown likelihood of the target MS being in the corresponding estimated area,
`
`and 1 indicates that the target MS is absolutely within the corresponding estimated area.
`
`Please replace the paragraph beginning on page 15, line 22 with the following paragraph:
`
`It is a further aspect of the present invention that the personal communication system (PCS)
`
`infrastructures currently being developed by telecommunication providers offer an appropriate localized

`Document: "Preliminary Amendment"
`
`infrastructure base upon which to build various personal location systems (PLS) employing the present
`
`invention and/or utilizing the techniques disclosed herein. In particular, the present invention is
`
`especially suitable for the location of people and/or objects using code division multiple access (CDMA)
`
`wireless infrastructures, although other wireless infrastructures, such as, time division multiple access
`
`(TDMA) infrastructures and GSM are also contemplated. Note that CDMA personal communications
`
`systems are described in the Telephone Industries Association standard IS-95, for frequencies below 1
`
`GHz, and in the Wideband Spread- Spectrum Digital Cellular System Dual-Mode Mobile Station-Base
`
`Station Compatibility Standard, for frequencies in the 1.8-1.9 GHz frequency bands, both of which are
`
`incorporated herein by reference. Furthermore, CDMA general principles have also been described, for
`
`example, in U.S. Patent 5,109,390, to Gilhausen, eta!, filed November 7, 1989, and CDMA Network
`
`Engineering Handbook by Qualcomm, Inc., each of which is also incorporated herein by reference.
`
`The paragraph beginning on page 16, line 6 has been replaced with the following paragraph:
`
`As mentioned in the discussion of classification FOMs above, the present invention can
`
`substantially automatically retrain and/or recalibrate itself to compensate for variations in wireless signal
`
`characteristics (e.g., multipath) due to environmental and/or topographic changes to a geographic area
`
`serviced by the present invention. For example, in one embodiment, the present invention optionally
`
`includes low cost, low power base stations, denoted location base stations (LBS) above, providing, for
`
`example, CDMA pilot channels to a very limited area about each such LBS. The location base stations
`
`may provide limited voice traffic capabilities, but each is capable of gathering sufficient wireless signal
`
`characteristics from an MS within the location base station's range to facilitate locating the MS. Thus, by
`
`positioning the location base stations at known locations in a geographic region such as, for instance, on
`
`street lamp poles and road signs, additional MS location accuracy can be obtained. That is, due to the low
`
`power signal output by such location base stations, for there to be signaling control communication (e.g.,
`
`pilot signaling and other control signals) between a location base station and a target MS, the MS must be
`
`relatively near the location base station. Additionally, for each
`
`location base station not in
`
`communication with the target MS, it is likely that the MS is not near to this location base station. Thus,
`
`by utilizing information received from both location base stations in communication with the target MS
`
`and those that are not in communication with the target MS, the present invention can substantially
`
`narrow the possible geographic areas within which the target MS is likely to be. Further, by providing
`
`each location base station (LBS) with a co-located stationary wireless transceiver (denoted a built-in MS
`
`above) having similar functionality to an MS, the following advantages are provided:
`
`Please replace the paragraph beginning on page 17, line 12 with the following paragraph:

`}''
`
`Application Serial No.: 091194.36.
`Document: "Preliminary Amendment"
`
`It is also an aspect of the present invention to automatically (re)calibrate as in (6.3) above with
`
`signal characteristics from other known or verified locations .. In one embodiment of the present invention,
`
`portable location verifying electronics are provided so that when such electronics are sufficiently near a
`
`located target MS, the electronics: (i) detect the proximity ofthe target MS; (ii) determine a highly
`
`reliable measurement of the location of the target MS; (iii) provide this measurement to other location
`
`determining components of the present invention so that the location measurement can be associated and
`
`archived with related signal characteristic data received from the target MS at the location where the
`
`location measurement is performed. Thus, the use of such portable location verifying electronics allows
`
`the present invention to capture and utilize signal characteristic data from verified, substantially random
`
`locations for location system calibration as in (6.3) above. Moreover, it is important to note that such
`
`location verifying electronics can verify locations automatically wherein it is unnecessary for manual
`
`activation of a location verifying process.
`
`Please replace the paragraph beginning on page 18, line 6 with the following paragraph:
`
`Furthermore, a mobile location base station includes modules for integrating or reconciling
`
`distinct mobile location base station location estimates that, for example, can be obtained using the
`

`
`The location estimating system of the present invention offers many advantages over existing
`
`location systems. The system of the present invention, for example, is readily adaptable to existing
`
`wireless communication systems and can accurately locate people and/or objects in a cost effective
`
`manner. In particular, the present invention requires few, if any, modifications to commercial wireless
`
`communication systems for implementation. Thus, existing personal communication system
`
`infrastructure base stations and other components of, for example, commercial CDMA infrastructures are
`
`readily adapted to the present invention. The present invention can be used to locate people and/or
`
`objects that are not in the line-of-sight of a wireless receiver or transmitter, can reduce the detrimental
`
`effects of multi path on the accuracy ofthe location estimate, can potentially locate people and/or objects
`
`located indoors as well as outdoors, and uses a number of wireless stationary transceivers for location.

`
`The present invention employs a number of distinctly different location computational models for
`
`•
`
`location which provides a greater degree of accuracy, robustness and versatility than is possible with
`
`existing systems. For instance, the location models provided include not only the radius-radiusrrOA and
`
`TDOA techniques but also adaptive artificial neural net techniques. Further, the present invention is able
`
`to adapt to the topography of an area in which location service is desired. The present invention is also
`
`able to adapt to environmental changes substantially as frequently as desired. Thus, the present invention
`
`is able to take into account changes in the location topography over time without extensive manual data
`
`manipulation. Moreover, the present invention can be utilized with varying amounts of signal
`
`measurement inputs. Thus, if a location estimate is desired in a very short time interval (e.g., less than
`
`approximately one to two seconds), then the present location estimating system can be used with only as
`
`much signal measurement data as is possible to acquire during an initial portion of this time interval.
`
`Subsequently, after a greater amount of signal measurement data has been acquired, additional more
`
`accurate location estimates may be obtained. Note that this capability can be useful in the context of911
`
`emergency response in that a first quick coarse wireless mobile station location estimate can be used to
`
`route a 911 call from the mobile station to a 911 emergency response center that has responsibility for the
`
`area containing the mobile station and the 911 caller. Subsequently, once the 911 call has been routed
`
`according to this first quick location estimate, by continuing to receive additional wireless signal
`
`measurements, more reliable and accurate location estimates of the mobile station can be obtained.

`
`At a more general level, it is an aspect of the present invention to demonstrate the utilization of
`
`various novel computational paradigms such as:
`
`(8.1) providing a multiple hypothesis computational architecture (as illustrated best in Figs. 8) wherein
`
`the hypotheses are:
`
`(8.1.1) generated by modular independent hypothesizing computational models;
`
`(8.1.2) the models are embedded in the computational architecture in a manner wherein the
`
`architecture allows for substantial amounts of application specific processing common or generic to a
`
`plurality of the models to be straightforwardly incorporated into the computational architecture;
`
`(8.1.3) the computational architecture enhances the hypotheses generated by the models both
`
`according to past performance of the models and according to application specific constraints and
`
`heuristics without requiring feedback loops for adjusting the models;
`
`(8.1.4) the models are relatively easily integrated into, modified and extracted from the
`
`computational architecture;
