Brief Patent Description - Full Patent Description - Patent Application Claims
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of U.S. patent application Ser. No. 09/024,278, titled "Broadcast Data Distribution System with Asymmetric Uplink/Downlink Bandwidths" and U.S. patent application Ser. No. 08/985,731, titled "System for Customized Electronic Identification of Desirable Objects". FIELD OF THE INVENTION [0002] This invention relates to information delivery systems and, in particular, to a system for customizing the information that is displayed to a viewer based on optimizing a match between information purveyors, such as advertisers, and the viewer in a manner that is executed local to an information delivery system. Problem [0003] It is a problem in information delivery systems to provide an information recipient with information that is pertinent to the recipient. This entails determining a match between information purveyors, such as advertisers, and the information recipient such that the information that is provided to the information recipient is desired by the information recipient and pertinent to the needs of the information recipient. Existing information delivery systems are based on static predictions of likely audiences, such as profiles of information recipients for different time periods of television broadcasts or in-store advertisements directed to a typical customer. These information delivery systems are static in nature in that they do not change in response to changes in the information receiving audience that they serve. Even in the context of systems such as the World-Wide Web, systems use stale aggregates to make speculative decisions. Therefore, existing information delivery systems are limited in their effectiveness in providing relevant information to their target audiences, since the defined target audiences represent a simple approximation of the ever changing actual audience. Solution [0004] The above described problems are solved and a technical advance achieved by the Location Enhanced Information Delivery System (LEIA) which customizes the information that is displayed to an information recipient based on optimizing a match between information purveyors, such as advertisers, and the information recipients who are local to an information delivery system. The present location enhanced information delivery system presents the information most suited to the real current audience, as measured by location information systems, rather than to a static predicted audience. While the preferred embodiment discloses a beaconing-style wireless technology, the system concept is easily extensible both to other location-information systems, such as license-plate scanning with cameras, and to utilizing the location-information for private displays of information in addition to public displays of information. [0005] The location enhanced information delivery system can be supported with conventional or advanced networking infrastructures. One example of an advanced networking infrastructure appropriate for the location enhanced information delivery system is the asymmetric bandwidth channel network disclosed in co-pending U.S. patent application Ser. No. 09/024,278, titled "Broadcast Data Distribution System With Asymmetric Uplink/Downlink Bandwidths" that provides a reduced memory architecture for network-attached elements. The location enhanced information delivery system can also utilize the information similarity measurement technologies disclosed in U.S. Pat. No. 5,754,939, titled "System for Generation of User Profiles for a System for Customized Electronic Identification of Desirable Objects" as a means of enhancing pre-fetching of information likely to be needed, with a consequent reduction in network bandwidth required to support the location enhanced information delivery system. The location enhanced information delivery system can protect users identities using a pseudonymity proxy server disclosed in U.S. Pat. No. 5,754,938 titled "Pseudonymous Server for System for Customized Electronic Identification of Desirable Objects". An additional advantage for public information-delivery capability of the location enhanced information delivery system is in its environment-friendliness, as the location enhanced information delivery system can determine when zero information recipients are local and turn off the display, resulting in a significant energy savings during idle periods. BRIEF DESCRIPTION OF THE DRAWING [0006] FIG. 1 illustrates in block diagram form the location enhanced information delivery system; [0007] FIG. 2 illustrates the network bandwidth dynamics typical of the location enhanced information delivery system; and [0008] FIG. 3 illustrates in flow diagram form the information flow in the present location enhanced information delivery system. DETAILED DESCRIPTION Definitions [0009] Relevant definitions of terms for the purpose of this description include: (a) an object available for access by the user, which may be either physical or electronic in nature, is termed "target object," (b) a digitally represented profile indicating that target object's attributes, is termed "target profile," (c) the information recipient who is looking for the target object, is termed "user," (d) a profile holding that user's attributes, is termed "user profile," (e) a summary of digital profiles of target objects that a user likes and/or dislikes, is termed the "target profile interest summary" of that user, (f) a collection of target objects with similar profiles, is termed a "cluster," (g) an aggregate profile formed by averaging the attributes of all target objects in a cluster, is termed a "cluster profile." Wireless Communication [0010] The advent of mobile wireless communication, in the form of pagers, cellular phones, and the like, has made on-demand location-independent communication possible. Many of these wireless technologies provide the ability to locate the call originating or receiving wireless subscriber station, via the unique terminal identifiers used for authentication and billing. Some of these wireless systems incorporate precise location determining apparatus, such as Global Positioning Systems. Except for a few examples, such as the Active Badge technology developed by the Olivetti Research Lab in Cambridge, UK, very little use has been made of the information that relates to the location of the wireless subscriber station, other than for locating the message/call destination as part of the wireless communication service. The Active Badge is very low power and intended for enclosed environments of small geographic scope, such as in a set of offices or on a campus site. The Active Badge technology has been used for tasks such as automatically opening door locks and automatic location of Active Badge wearers. The present location enhanced information delivery system provides a novel means of integrating subscriber location information into the design of advanced communication services. Cellular Telephony [0011] Cellular telephone systems are one example of wireless communication systems. The cellular telephone system divides the service area into "cells," in which the assigned radio spectrum is channeled in some fashion using digital or analog technology. Each cell is provided with a base station to which mobile subscriber stations connect to make a wireless communication connection. The handoff of a communication connection that exists between a mobile subscriber station and a base station to another base station entails executing the steps of: establishing a wireless communication connection from the mobile subscriber station to the base station in the cell into which the mobile subscriber station is about to enter, transitioning the existing wireless communication connection to the new wireless communication connection, and then releasing the old wireless communication connection. The mobile subscriber stations are interconnected with the traditional telephony infrastructure, and thus ubiquitous cellular service can be achieved by the provision of sufficient base stations. The mobile subscriber stations periodically emit an identifying token, so that the base station knows they are present in the service area of the base station. This same beaconing behavior can be exploited to construct the location enhanced information delivery system, because while it is low-cost and requires low bandwidth, it can be integrated with sophisticated delivery systems to provide customizable information to the mobile subscriber station. [0012] Classic cellular telephony[x,y] is based on the use of a set of radio frequencies chosen from a set (a "band" of spectrum), two of which are required per connection (one to send, the other to receive). These frequencies are required during a call, but otherwise not used, so that many cellular telephones can be present in a "cell" but only the active telephones consume frequencies. "Cells" are regions where selected sets of radio frequencies are in use. Adjacent cells do not use the same frequencies for calls to prevent interference. Cells are often arranged as hexagons since hexagons "tile" the plane. [0013] Calls are set up and handed-across cell boundaries using a signaling channel. The signaling channel uses a common protocol which all cell phones understand, Signaling System 7 (SS7). The handset periodically broadcasts a unique identifier (which in the telephone system, maps directly to a telephone number) which is "burned in" to a chip in the telephone. This number is used by the base station for the cell to identify the phone for billing purposes, and to find its "home location". When a cellular telephone enters a base station's cell, the base station uses the ID to find its home Mobile Telephone Switching Office (MTSO), from which calls appear to be traveling to and from as they are made (an interesting consequence is that a New Jersey cellular telephone operating in California will route a call to the East Coast and back, even for a location a block away). The channel between the local Mobile Telephone Switching Office and the home Mobile Telephone Switching Office is carried over the traditional telephone network (e.g., landlines). When moving between cells, the telephone and two base stations use a handoff protocol so that the connection is maintained; it essentially involves setting up frequencies in the destination cell to switch to. Handoff is triggered when the telephone detects two "beacons" of approximately equal strength; each base station emits a beacon (like a radio "lighthouse") so that it can be detected. [0014] The location enhanced information delivery system 100 uses similar mechanisms for location tracking--in fact, one attractive implementation technology for tracking in the location enhanced information delivery system 100 is the telephone number emitted by the cellular handset. Where the cellular network uses the local Mobile Telephone Switching Office as a dumb proxy to the home Mobile Telephone Switching Office via telephone circuits, the location enhanced information delivery system 100 use of a profile fetched from one or more locations, coupled with information from a multiplicity of sources, provides a much richer source of information than a call acceptance decision. The use of this information at the location(s) where the location enhanced information delivery system 100 location ID is detected is much richer, because the use of the information is location-customized, e.g., to a billboard, kiosk, proximity to a vendor, etc. The cellular handset provides the same service everywhere (in fact, that is one of its appeals), which is a telephone circuit. [0015] The integration of the location enhanced information delivery system 100 with the telephony infrastructure provides a junction point for information analysis systems. The beacon capability of the mobile subscriber stations can be used to identify a user, and using this subscriber identification information, to locate and fetch a user profile for the identified subscriber. Simplistic user profiles have been used as part of Personal Communication Service systems, primarily to reduce traffic loads on the network, to reduce the radio bandwidth used, and the traffic load on the SS7 signaling network.
