Definitions

  • the present invention relates generally to a wireless paging system, and more particularly, to a method and system for sending localized information to a two-way paging device.
  • Conventional wireless paging systems are typically one-way communication systems that can only send messages in a forward direction from a service provider to a subscriber " s paging device. Because these one-way paging systems have no knowledge of the locations of paging devices, each message is distributed to all paging transmission facilities of a service provider, which can cover a geographic area such as North America. Each facility then transmits the message so that if an addressed paging device is within a coverage area of one of the transmitters, the message will be delivered to the paging device. This type of one-way paging system is often called a broadcast paging system.
  • the message capacity of such a broadcast paging system is not used efficiently because each message is transmitted by every transmission facility in the system, but only one transmission facility will actually deliver the message to the subscriber's paging device. Therefore, the majority of the message traffic of any given transmitter will typically be occupied by messages addressed to pagers that are not within the coverage area of the transmitter. Accordingly, subscriptions to broadcast-type nationwide paging services are relatively expensive.
  • the messages sent in these one-way paging systems can be intended for one subscriber or for multiple subscribers. For example, a message intended for one subscriber's paging device may inform that subscriber that a third party is attempting to contact them.
  • These paging devices are generally tuned to a predetermined frequency that is shared with many other paging devices.
  • the reception of a particular message by a paging device activates an acoustic, vibrating, or visible alert, thereby indicating to the subscriber that a message has been received.
  • One of the many disadvantages of these one-way paging systems is that they are not capable of verifying whether a message was received by a subscriber's paging device.
  • the addressability of a one-way paging device is determined by a unique identifier stored within the pager.
  • the unique identifier may be considered analogous to a telephone number.
  • it is often referred to as a "capcode" because in early paging devices, a code number was printed on a cap that fit on top of the pager.
  • the capcode is typically a four or seven digit number. This number is used by the paging system to generate the right sequence of tones to alert a specific paging device.
  • the capcode is the unique serial number that paging system transmitters transmit to notify a paging device of an incoming
  • Examples of one-way paging messages intended for multiple subscribers include headline news, sports scores, and financial information. More specifically, companies such as Mobeo, Inc. (formerly DocuPro, Inc.) of Bethesda, Maryland, provide real-time quotes of financial instruments, energy instruments, world metal markets, and late-breaking news.
  • a subscriber of Mobeo can receive such message information using a one-way paging device such as the ADVISORTM Gold pager manufactured by Motorola, Inc. of Schaumburg, Illinois. The same message information is broadcast by every transmission facility of the wireless data network supporting Mobeo.
  • the addressability of a one-way paging device is determined by its capcode. These capcodes can be reprogrammed such that multiple paging devices have the same capcode.
  • each paging device can receive the message information broadcast by the transmitters. So long as a paging device having the Mobeo specific cap code is within a coverage area of one of the transmitters, the message can be received by the paging device.
  • a disadvantage of these one-way paging systems is that unauthorized parties can reprogram capcodes in order to receive information without subscribing to a service. Thus, service providers can lose significant revenue if these reprogrammed paging devices are distributed.
  • Another disadvantage of these one-way paging systems is that they do not verify whether a paging device has received a message.
  • a further disadvantage of these one-way paging systems is that the message information sent to the multiple subscribers is not tailored to the interests of each subscriber. Rather the message information is generally created to appeal to a broad spectrum of subscribers regardless of their individual interests and/or needs. For example, if individuals subscribe to a nationwide sports paging service, the message information may include the final results of the current day's baseball games because this type of information would probably appeal to a broad spectrum of subscribers. However, since the performance of a Baltimore Orioles' player is probably not of interest to a subscriber located in Seattle, such information cannot be economically provided to a Baltimore subscriber.
  • ReFLEXTM Protocol for two-way paging.
  • ACK acknowledgment
  • ReFLEX was designed to modify an existing oneway FLEXTM protocol, its two-way capabilities are somewhat limited.
  • ReFLEX For example, for messages originating at a paging device, ReFLEX support data rates of only 800, 1600, 6400, or 9600 bits per second (bps). Additionally, it typically takes on the order of a few minutes, from the time a message is sent to a paging device, to receive an ACK message using ReFLEX. Accordingly, ReFLEX has not satisfactorily overcome most of the above discussed disadvantages. More generally, ReFLEX has not proved acceptable for real time two-way communications.
  • More robust two-way wireless paging systems include the BellSouth Wireless Data network (also known as the RAM Mobile Data network) and the ARDIS network. These networks provide two-way paging using paging devices such as the Inter@active PagerTM manufactured by Research In Motion (RIM),
  • This RIM two-way pager provides fast two-way delivery of full-length, error-free, alphanumeric messages with guaranteed delivery. For example, when using the RIM pager with the BellSouth Wireless Data network or the ARDIS network, an acknowledgment message is received within a few seconds of the original message being sent. Thus, such networks and paging devices are beginning to provide two-way wireless paging services that have not previously been available.
  • Two-way paging devices are addressed through the use of unique identifiers. Some identifiers are programmable and others are hard coded and fixed in a paging device. A programmable and/or hard coded identifier can be used to address a specific paging device. Because a two-way paging device transmits messages that include these unique identifiers, fraud is more likely to be detected.
  • the present invention is directed toward a method and system for providing localized information to a uniquely identifiable two-way wireless communications device via a wireless communications system that includes a plurality of cell sites that are coupled to a communications network, wherein each cell site has a corresponding coverage area.
  • the method of the present invention includes the steps of receiving a request from a first two-way wireless communications device via a first cell site, identifying the first cell site, determining information correlated to the request and the first cell site, and sending a response to the first device based on the information.
  • the first cell site is identified based on the request.
  • the first cell site is identified by identifying a first unique identifier of the first device based on the request, and by accessing a database that correlates cell sites and unique identifiers to thereby determine the identity of the first cell site based on the first unique identifier.
  • the step of determining the information includes the steps of determining first information relating to the request and determining second information relating to the first cell site. The information is then determined based on the first information and the second information.
  • the first information can, for example, specify a class of information.
  • the second information can, for example, specify a location of a cell site.
  • a first location of the first cell site can be determined by accessing a location database that provides location related information for each of the plurality of cell sites. The information can then be determined based on the first location and the request.
  • a first class relating to the request can be determined. Then, by accessing a class database that provides a plurality of classes of information for each of the plurality of cell sites, the information can be determined based on the first class and the first cell site.
  • the class database can include, for example, class information such as weather, sports, movie listings, restaurant information, business and government listings, emergency address/phone numbers, public transportation information, airline schedules, and automatic teller machine locations.

  • Communications system 100 includes a plurality of cell sites 102 each having a coverage area that is typically about 5 to 10 miles in diameter. A coverage area of one cell site often overlaps a portion of a coverage area of another cell site, which are illustrated for exemplary purposes by the hexagonal regions.
  • Each cell site 102 includes an antenna 104 for transmitting and receiving paging messages to and from two-way wireless paging devices 108 that are located within a geographic coverage area of the cell site 102. Alternatively, separate antennas may be used for sending and receiving messages, as would be apparent to a person skilled in the relevant art.
  • Each cell 102 is coupled to communications network 110, which in a preferred embodiment is an X.25 packet switched network. Communications network 110 may include, but is not limited to, land based links such as fiber optics or terrestrial microwave, and/or satellite based links, as would also be apparent to a person skilled in the relevant art.
  • Each cell site 102 is in communications with a message system center (MSC) 120 that includes a subscriber database that maintains records of all subscribers on the system, a unique identity sequence for the subscriber's paging device, and an indication of the cell site from which the paging device last sent a message (such as an acknowledgment message).
  • MSC message system center
  • communications between each cell cite 102 and MSC 120 is accomplished through communications network 110.
  • each cell site 102 can have a dedicated link to MSC
  • Communications network 110 can be coupled to public switched telephone network (PSTN) 1 12 so that a caller can use PSTN 112 to send a message to paging device 108, and vice versa.
  • PSTN public switched telephone network
  • a message can also be sent from one paging device 108 to another paging device 108 using communications system 100.
  • communications system 100 is the Bell South Wireless Data network (also known as the RAM Mobile Data network) or the ARDIS network, which are both well known two-way nationwide wireless packet data networks.
  • Two-way wireless communications device 108 (also referred to herein as a paging device) typically identifies itself to MSC 120 by sending a registration or identification signal.
  • Such signals include a data field including at least one unique identifier, such as a Mobile Identification Number (MIN) and/or Electronic Serial Number (ESN).
  • MIN Mobile Identification Number
  • ESN Electronic Serial Number
  • a MIN which can be reprogrammed, is analogous to a telephone number.
  • An ESN is hard-coded and fixed such that it difficult, if not impossible to change.
  • Some devices include both a MIN and an ESN.
  • the paging device used in the preferred embodiment of the present invention discussed in more detail below, only includes one unique identifier, known as a Mobile Access Number (MAN), which is similar to an ESN in that it is hard-coded and fixed.
  • the identification signal sent by paging device 108 can include one or more of the above discussed unique identifiers. Such identification information can be periodically transmitted by paging device 108 and/or included with other types of rhessages sent by paging device 108.
  • An optional function of MSC 120 is to determine whether the unique identifier of a paging device is valid.
  • a received unique identifier such as a unique identity sequence comprising a string of digitally represented alphanumeric characters, can be compared to a database maintained of unique identifiers (i.e., MIN, ESN, MAN) to detect fraud.
  • MSC 120 can keep track of the approximate whereabouts of each paging device 108 by keeping track of which cell site 102 a message, sent by a paging device 108, originated. When MSC 120 is thus informed of the approximate whereabouts of each individual paging device 108, it can later limit the number of cell sites 102 from which it transmits a message addressed to a particular paging device 108. MSC 120 can even limit the transmission of a message to only one cell site 120 having a coverage area within which the particular paging device 108 is believed to be located. The coverage area of a limited number of cell cites 102 (possibly only a single cell site or a last know site and its adjacent sites) shall be referred to as a targeted coverage area.
  • the targeted area can be the area covered by a single cell site or a slightly larger area that is also covered by a few adjacent cell sites.
  • This limited or "targetted paging" is much more efficient than broadcast-type paging where a message is transmitted from every cell site, regardless of a location of a paging device 108 to which the message is addressed.
  • Service providers 114 are supported by communications system 100. That is, communications system 100 provides for message delivery between a service provider 1 14 and one or more paging devices 108. Service providers 1 14 can communicate directly with paging devices 108 or indirectly with paging devices 108 via communications network 110. Alternatively, service providers 114 can communicate with communications network 110 through PSTN 112.

Additionally, service providers 114 can initiate the sending of information to a paging device 108. This can be done periodically or upon a triggering event. Additional details about the types of services and the information provided by services providers 114 are discussed below.

Abstract

L'invention concerne un procédé et un système permettant de fournir des informations localisées à un unique dispositif de communication bidirectionnelle sans fil identifiable, par l'intermédiaire d'un système de communication sans fil comprenant plusieurs stations cellulaires couplées à un réseau de communication. Le procédé de la présente invention consiste tout d'abord à recevoir une demande émise par un premier dispositif de communication bidirectionnelle sans fil par l'intermédiaire d'une première station cellulaire, puis à identifier cette première station cellulaire, à déterminer les informations liées à cette demande et à cette station cellulaire, et enfin à envoyer une réponse au premier dispositif, sur la base de ces informations. Dans un mode de réalisation, on identifie la première station cellulaire sur la base de la demande, et dans une variante, on identifie cette première station cellulaire en identifiant, sur la base de ladite demande, un premier identificateur unique du premier dispositif, et en accédant à une base de données liant les stations cellulaires à des identificateurs uniques, ce qui permet de déterminer, sur la base de ce premier identificateur unique, l'identité de la première station cellulaire. Dans un mode de réalisation, cette étape consistant à déterminer les informations implique notamment de déterminer des premières informations concernant cette demande, ainsi que des secondes informations concernant la première station cellulaire. On détermine ensuite les informations sur la base de ces premières et secondes informations, les premières informations pouvant par exemple porter sur une catégorie d'informations, et les secondes concerner des informations de localisation.
