Description

= CA 02407419 2008-01-07 INrORMATION PORTAL

FIELD OF IN-VENTION
This iiivention relates to conuntuiication systems, and in partictilar, to wireless conlm.unication systems.

BACICGROUPdD
Mobile processing-systems, such as portable computers and personal digital assistauts, are often provided with the ability to establish wireless connections with other processing systems. Such wireless connections enable a user to access internet sites while traveling. A user thus equipped is able to obtain real-time infoiznation from an iizternet site aud to act immediately on the basis of that infoznlation. For exarnple, a user on the way to the airport may use a mobile processing-systein to discover that a flight has been cancelled and that it may be preferable to simply ttu~n around and go home.

As a practical matter, however, it is difficult for a user of a mobile processing-system to conveniently acquire timely iuifoxrnation while traveling. The process of identifying and accessing a web site can be cumbersome and difficult to attend to while coping with the exigencies of travel. In addition, the speed of wireless data transmission is itself linvted by numerous physical constraints. For example, high speed data transmission requires high bandwidth. Such bandwidth may not be available simply because a finite spectrum must be shared by many channels. Inadequate signal-to-noise ratio, resulting from noise or inulfii-path reflections, can result in high error rates, which in t-Ltni require frequent retransmission of data packets.

SUMIVI.A.RY
A systeni according to the invention provides high-speed wi.reless convnunicatioxs to a mobile processing system. The system maintains one or more information poi-tals that provide high-speed wireless access to a local area networlc. Because of the limited spatial extent of an information portal, a low-power but high-bandwidth chaiulel can be maintained within the infoi-ination portal. Within t11e Iinlited spatial extent of the information portal, wireless data cominuuication is established at rates much liigher thatl those available in those wireless data conuuuni.cation systems that provide wireless data commuiii.cation over public ail.vvaves.

A communication system incorporating the invention includes a stationary transceiver defining an information portal in its immediate vicinity. A local server in communication with this stationary transceiver is configured to respond to a mobile processing-system present within the information portal.

Typically, the local server is configured to perform a function on the basis of the identity of the mobile processing-system. This function might be to provide selected data to the mobile processing-system, to provide interactive access to a computer network, or to perform various fiuictions associated with the operation of a building that houses the stationary transceiver.
Examples of such functions include permitting building access to a portion of the building, or controlling an elevator in the building.

In one aspect of the invention, the local server is configured to establish a communication linlc between the mobile processing-systein in the information portal and a selected location. The communication linlc can be an audio link, a video link, or a two-way communication link.

Various types of transceivers can be used as stationary transceivers. For example, the stationary transceiver can be a radio transceiver, an optical transceiver, an infrared transceiver, and an acoustic transceiver.

Information is cominunicated to the mobile processing system when the mobile processing system is within an information portal. Consequently, the stationary transceiver, and hence the information portal that it maintains, is deployed at locations in which commuters or travelers are expected to linger momentarily. Such locations include elevators, elevator lobbies, waiting areas at transportation nodes, for exainple train platforms at train stations, airplane gate areas at airports, and even the transportation vehicles themselves.

In another embodiment, the communication system also includes a fulfillment server in communication with the local server. The fu.lfillment server has access to a wide area networlc.
The wide area network can be a global computer network, such as the internet.

The fulfillment server can include a user-interface to enable a user to specify certain actions. Examples of suc11 actions include malcing selected information available for transmission to a mobile processing system at an information portal, or requesting that the fulfillment server send, to the mobile processing system, a message indicating the occurrence of a selected event.
-2-s In one aspect of the invention, the fulfillment server is configured to provide interactive services to the mobile processing system while the mobile processing system is in an information portal. Examples of such interactive services include email or internet access.

To enhance performance, it is useful to provide a cache at the local server.
Such a cache is used to accumulate information intended to be transmitted to a mobile processing system. This
3.0 information remains in cache until the mobile processing system enters an information portal.
Once the mobile processing system for which the accumulated information is intended enters an information portal, the information in cache is relayed to the mobile processing system.

In another embodiment, the communication system includes a plurality of stationary transceivers, each configured for wireless communication with a mobile processing system is present in a corresponding information portal; and a server system in communication with each of the stationary receivers. The server system has a link to a global computer network. this enables the server system to provide the inobile processing system with wireless access to the global computer network.

The invention also includes a method for providing a mobile processing system with 20 wireless access to a global computer network. The method includes maintaining an information portal and establishing wireless communication between the mobile processing system and a server system following entry of the mobile processing system into the information portal. Once communication has thus been established, a link between the server system and the global computer network is provided.

According to one aspect of the present invention, there is provided a communication system comprising: a stationary transceiver defining an information portal in a vicinity thereof; and a local server in communication with said transceiver, said local server being configured to respond to entry of a mobile processing-system present within said information portal, and to provide, to said mobile processing system, data previously requested for said mobile processing system prior to entry of said mobile processing system into said information portal.

According to another aspect of the present invention, there is provided a communication system comprising: a plurality of stationary transceivers, each configured for wireless communication with a mobile processing system present in a corresponding information portal; and a server system in communication with each of said stationary receivers, said server system having a link to a global computer network and thereby providing said mobile processing system with wireless access to said global computer network said server system including a server configured to provide, to said mobile processing system, in response to entry of said mobile processing system into an information portal, data previously requested for said mobile processing system prior to entry of said mobile processing system into said information portal.

According to still another aspect of the present invention, there is provided a method for providing a mobile processing system with wireless access to a global computer network, said method comprising: maintaining an information portal;
establishing wireless communication between said mobile processing system and a server system following entry of said mobile processing system into said information portal; and causing data previously requested for said mobile processing system prior to entry of said mobile processing system into said information portal to be provided to said mobile processing system, in response to entry of said mobile processing system into said information portal.

BRIEF DESCRIPTION OF THE FIGURES
FIG. 1 is a communication system incorporating the invention.
-3b-s FIG. 2 illustrates an application of the communication system of FIG. 1; and FIGS. 3 and 4 show additional coirununication systems incoiporating the invention.
DET_4ILED DESCRIPTION
Referring to FIG. 1, a communication system 10 incorporating the invention includes a local server 12 in data communication with one or more stationary transceivers 14a-n across a a.o private networlc. Each stationay transceiver 14a-n maintains a corresponding information portal 16a-n ea.tending around a vicinity thereof. When a person carrying a mobile processing-system 18, for ea.aniple a portable computer or a portable digital-assistant, en.ters one of these infoimation portals 16a, the stationary transceiver 14a maintaining that iilformation portal 16a establishes wireless coniniunication between the local server 12 and the mobile processing-15 systein 18.

The mobile processing-system 18 and the stationary transceiver 14a can establish wireless conununicatioii by transinitting and receiving electromaglietic waves or acoustic waves modulated by data. ui the case of electromagnetic waves, the waves can be radio-frequency waves, infiared waves, optical waves, or eleetromagnetic waves having any other frequency 20 suitable for short-range data-commwaication. Acoustic waves are typically ultrasonic or mega sonic waves.

In the case of radio-frequency waves, the establishment of the conununication link can be completely passive, with no action required of the person other than entry into the information portal 16a. In the case of infrared or optical waves, or other waves having wavelengths much 25 sllorter than nearby scattering structures, the person establishes communication by pointing a port on the mobile processing-systeni 18 toward the stationary transceiver 14a.

The stationary transceivers 14a-n can be deployed within a building in conjunction with eleva.tor displays and lobby displays as described in issued US Patezit Nos. 6,073,727 and 6,349,797. This deployment is 30 advantageous because the display can then be used to conununicate infonnation to the persoii carrying the mobile processing-system 18. In addition, the display is already in data cominunication witlr the local server 12 and can therefore be easily nrodified to acconlmodate the stationary transceiver 14a. However, stand-alone stationary transceivers 14a-n can also be deployed ht various locations without the presence of a nearby display.
-4-Stationary transceivers 14a-n are typically deployed at locations in which carnmuters and other travelers are likely to linger in the course of their travel. This ensures that the person is in an information data portal 16a-n long enough for meaningful data transmission to occur.

The local server 12 is also connected to one or more peripheral devices 20.
Such peripheral devices can include elevator control system 22, building security systems 24, bullding communication systems 26, building environmental-control-systems 28, and other systems that govern additional aspects of building functionality. These connections enable the local server 12 to control building functions in response to the identity and movement of a person canying a mobile processing-system.

A local area network 30 links the local server 12, the peripheral devices, and the stationary transceivers 14a-n. These links can be wired linlcs, wireless links, or a mixture of bot11 wired and wireless links.

In operation, a person carrying a mobile processing-system 18 enters one of the information portals 16a-n. The mobile processing-system 18 and the stationary transceiver 14a then establish communication, thereby providing a data path between the local server 12 and the mobile processing-system 18. This enables the local server 12 to identify the mobile processing-systein 18. The local server 12 can then interact with the peripheral devices in a manner consistent with the identity of the mobile processing-system 18.

To illustrate examples of some of the various types of interaction that are possible, it is instructive to follow the activities of a typical building tenant upon arrival at the building. FIG. 2 illustrates the progress of a tenant who, at time t,, enters a parking lot 32 adjacent to a building 34.

Throughout this detailed description, reference is occasionally made to a tenant or user as having been detected and identified while within an information portal 16a-n.
It is understood, however, that it is the mobile processing-system 18, and not the tenant or user, that is in fact being detected and identified.

Referring now to FIG. 2, a first stationary transceiver 36a maintains a first information portal 38a at the entra.nce to the parking lot 32. As the tenant drives through this first information porta138a, the local server 12 identifies the mobile processing-system 18 and notes a time-of-entty to be used later for calculating an appropriate parking fee.
-5-s After a few minutes, the tenant parks and begins to wallc toward a nearby elevator lobby 40. At time tZ, as the tenant approaches the elevator lobby 40, he enters a second information portal 38b maintained by a second stationary transceiver 36b. When the tenant enters this second inforination portal 38b, the second stationary transceiver 36b establishes communication between the local server 12 and the tenant's mobile processing-system 18. The local server 12 records the floor on which the tenant has parked. This data is later retrieved and used to program the elevator when the tenant re-enters an elevator at the end of the day. The local server 12 then interacts with the elevator control system 22 to call an elevator 42. By the time the tenant reaches the elevator lobby 40, the elevator 42 is already well on its way to meeting him.

The local server 12 also determines the floor that the tenant works on and, in a further interaction with the elevator control system 22, instructs the elevator 42 to proceed to that floor once the tenant enters a third information portal 38c maintained by a third stationary-transceiver 36c within the elevator 42. The local server 12 then interacts with the building environmental-control-systems 28 to turn on heat or air-conditioning at locations selected on the basis of the tenant's identity.

When the elevator 42 arrives to pick up the tenant at the designated floor of the parking garage, the local server 12 starts a timer. If the tenant fails to enter the third inforlnation portal 38c (located in the elevator 42) within a selected time, the local server 12 sends a message to building security personnel alerting them to the possibility of a mishap.

At time t37 the tenant enters the third information porta138c by boarding the elevator 42.
The third stationary-transceiver 36c in the elevator 42 detects the tenant's entry into the third information portal 38c. Without further intervention from the tenant, the elevator 42 then carries the tenant to the floor selected by the local server 12.

After a few moments, the elevator reaches the selected floor 42, whereupon the tenant exits the elevator 42. At time t4, the tenant enters a fourth information portal 38d maintained by a .30 fourth stationaly transceiver 38d. The local server 12 detects the tenant's entry into the fourth information portal 38d and sends an appropriate message to the building security system 24. In response, the building security system 24 unlocks an appropriate door 44 for the tenant.

In the unlikely event that the elevator 42 becomes stuclc between floors, the elevator control systein 22 detects the existence of this condition and signals the local server 12. The local 3 5 server 12 then checks to see if there are any occupants within the information portal maintained in the elevator 42. If there are such occupants, the local server 12 uses the information portal maintained in the elevator 42 to provide a real-time communication link between the occupants
-6-and building security personnel. The communication link can be a streaining video or audio link.
Preferably, the communication link- thus established is a two-way video link.

The communication system 10 can also be used to broadcast announcements and other data directly to the mobile processing-system 18. In such a case, a tenant enters any one of several infonnation portals scattered throughout the building 34 while carrying a mobile processing-system 18. Upon entry into any such information portal, the local server transmits appropriate data to the mobile processing-system 18.

Another embodiment, shown in FIG. 3, also includes a fulfillment server 46 that interfaces the local server 12 with selected content providers 50a-c across a global computer networlc 52. The fulfillment server 46 communicates with the local server 12 over a private i5 networlc 48 or a virtual private networlc. Data transport over the private network 48 can be carried out using a fraine relay or xDSL service.

The addition of the fulfillment server 46 to the communication system permits the local server to relay information gathered by the fulfillment server 46 to a user whenever that user enters one of many information portals dispersed throughout a building 34. A
user-interface 54 associated with the fulfillment server 46 enables a user to request delivery of selected information from the content providers to the user's mobile processing-system 18.

To illustrate the types of services that can be provided, it is useful to consider a user who wants to obtain a traffic report at the end of every working day. The activities of such a user are illustrated in FIG. 3.

At time tõ the user accesses the user-interface 54 of the fulfillment server 46 using a web-browser 56 executing on the user's computer system 58. Through this user-interface 54, the user instructs the fulfillment server 46 to routinely make a traffic report available everyday.

At an appropriate time, and without fiuther intervention by the user, the fulfillment server 46 retrieves traffic information from a content provider 50a. The fulfillment server 46 then identifies the local server 12 associated with that particular user. After doing so, the fulfillment server 46 sends the requested information to that local server 12. The local server 12 then stores that information in a cache 60 for delivery to the user's mobile processing-system 18 upon entry of that system into an information porta116a-n.

At time t2, while the user is in the elevator 42, the user enters or passes through an infonnation portal while carrying the inobile processing-systein 18. The stationary transceiver
-7-14a maintaining that information portal sends a message to the local server 12 indicating the presence of the user's mobile processing-system 18. In response, the local server 12 retrieves the requested information from cache and sends it to the stationary transceiver 14a. The stationary transceiver 14a then transmits that data directly to the mobile processing-system 18. In this way, by the time the user leaves the information portal 16a, the mobile processing-system 18 will have collected the desired data.

The foregoing example illustrates the manner in which the communication system provides programmed services. Such programmed services are characterized by a request that particular content be made available for delivery during a particular time interval. However, the coinmunication system 10 can also provide real-time services. Real-time services are characterized by the delivery of a message indicating that a particular event has occurred.
To illustrate the use of the communication system 10 in providing real-time service, consider a user who wants to be alerted when, for example, a price of a particular stock has risen above a pre-determined level. The user would then access the user-interface 54 of the fulfillment server 46 using a web-browser 56 executing on the user's computer system 58.
Upon doing so, the user could then request that the share price of a stock be monitored and that a message be sent if the share price reaches or exceeds the pre-determined level.

In response to the user's instruction, the fulfillment server 46 periodically accesses one or more of the selected content providers 50a-50c throughout the day to monitor the price of the stock. If the price exceeds the pre-determined threshold, the monitor sends a message to the local server 12 associated with the user. The local server 12 then caches this message for subsequent delivery to the user whenever the user enters an information portal 16a-n while carrying a mobile processing-system 18.

When the user carries the mobile processing-system 18 into an information portal 16a, the local server 12 detects the presence of the mobile processing-system 18, retrieves the message from cache, if any, and transmits it to the mobile processing-system 18.

A communication system 10 as described herein can also provide interactive services to a user. For example, the local server 12 can provide information such as locations of nearby restaurants, automated teller machines, train stations, and other services.
Such a service is useful for travelers who are unfamiliar with the immediate neighborhood. In this case, the user need not interact witli a fixlfillment server 46 beforehand. Such information can be available upon request whenever a user carrying a mobile processing-system 18 enters an information portal 16a.
-8-
9 PCT/US01/40603 Although the foregoing description teaches a communication system 10 installed in a building, such as an office building or a hotel, similar communication systems can be installed virtually aliywhere that a person carrying a mobile processing-system 18 can be expected to linger moinentarily. For example, communication systems of the type described herein can also be installed at such diverse locations as airports, train stations, train cars, and cruise ships.

A user of the coinmunication system 10 need not be confined to a particular local server 12. For example, a communication system 10 can be installed to encompass a set of train stations, each of which has its own local server 12, as shown in FIG. 4.

In this application, each train station (of which only two are shown in the figure) includes a local server 12a-b having a local cache 60a-b. The first local server 12a provides a link 1s between four stationary traiisceivers 14a-d at a first train station and a fulfillment server 46. The second local server 12b provides a linlc between four additional stationary transceivers 14e-h at a second train station and the fulfillment server 46. The fulfillm.ent server 52 provides a link to a plurality of content providers 50a-c across a global computer network 52. It is understood that the number of stationary transceivers in each train station and the number of train stations can be varied without departing from the scope of the invention.

When a local server 12a detects the user at the train station or entering the train, a link is established in the manner already described in connection with FIGS. 1 and 3.
would be delivered as already described above. For interactive services, such as email, or for extended services, such as music, the local server 12 would accept the request, cache it, and wait for the next train station to complete the request. The user would then be notified when the information becomes available.

It is to be understood that while the invention has been described in conjunction with the detailed description thereof, the foregoing description is intended to illustrate and not limit the scope of the invention, which is defined by the scope of the appended claims.
Other aspects, advantages, and modifications are within the scope of the following claims.
What I claim as new, and secured by letters patent is:
