TECHNICAL FIELD 
       [0001]    This disclosure relates to the control and customization of applications resident on a wireless device from locations remote therefrom and more specifically to systems and methods for allowing applications resident on a mobile device to be controlled using the text messaging capability of the wireless network. 
       BACKGROUND OF THE INVENTION 
       [0002]    Electronic device-based applications, particularly wireless device based applications, allow users to request information from various sources to be delivered to the device. However, the returned information is transient in nature in that it can not be stored in a manner that allows the content of the returned information to be used other than for display or modified by a sender or trusted third party. A particular problem is that the returned information cannot later be addressed for content. 
         [0003]    Another problem results from the fact that wireless device protocols are typically arranged such that the user must request information and such that information cannot be easily “pushed” to the device using standard Hyper Text Transfer Protocol (HTTP) network protocols. Thus, it is difficult to externally trigger from a remote location an application that resides on a particular device to perform a function. 
         [0004]    By way of example, assume a user makes a reservation from his/her cellular telephone for a flight to Las Vegas. When that flight is confirmed, it would be nice to have the particulars of the flight posted in the user&#39;s calendar application. At some point in the future, the user will want to know the gate information and the flight status. Using existing HTTP protocols it is impractical to integrate messages sent from the server into the user&#39;s applications. Certainly, the user can receive a text (SMS) message or an email message, but those messages are stand-alone messages and their content is not in a format that can be readily used other than for display purposes. 
       BRIEF SUMMARY OF THE INVENTION 
       [0005]    Systems and methods are provided that allow an application residing on a user device to intercept messages directed to that device and to extract control information and/or data from the intercepted messages for use by the application. In one embodiment, the intercepted message can cause the application to change its configuration or to present information to the user that came from a sending website. In another embodiment, a message from a device can trigger a website (such as an airline website) to send back a desired piece of data. The returned data can, for example, contain a flag, which directs the data to a formatting server. The formatting server then converts the data into a format that allows the data to be intercepted by the desired application on the user device. This then allows the desired data to be presented to the user in the context of an application resident on the user&#39;s device. 
         [0006]    The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0013]      FIG. 1  shows one embodiment of a system, such as system  10 , in which the concepts of the invention can be practiced. In  FIG. 1  there is shown a link from a user device, such as cellular telephone  15  to website  11 . This link extends from the user device through a carrier network, such as network  14  and via service center  12  to the desired website. The message returned from website  11  contains an HTTP request against service center  12 . The service center then queues a Short Message Service (SMS) message back to device  15  through an SMS broker, such as broker  13 . Broker  13  then routes an SMS message through any carrier network, such as network  14 , which need not be the same network that was used for the originating message from the device. 
         [0014]    An SMS message, also referred to as a text message, is a service for sending short messages of up to  160  characters ( 224  characters if using a  5 -bit mode) to mobile devices, including cellular phones and PDAs. SMS messages do not require the mobile phone to be active and within range and the message will be held for a number of days until the device is active and within range. SMS messages are transmitted within the same cell or to anyone with roaming service capability. 
         [0015]    When the incoming text message arrives at the user&#39;s device it is intercepted, under control of the device processor and an application, such as application  31  (as will be discussed), running on the device. This is possible because application  31  is registered with the device operating system when it was loaded on the device. Application  31  then routes the incoming message to the proper specific application in accordance with the data contained in the text message. Thus, in the situation with the flight reservation to Las Vegas (as discussed above), information pertaining to that flight is routed to a specific application, such as to air travel application  22 - 1  (shown in  FIG. 2B ), which application is dedicated to air travel data pertaining to the device user. 
         [0016]      FIGS. 2A through 2F  by way of example, show one environment, called a tiled environment, in which the concepts of the invention can be used. In such an environment, the device may have on it a number of “tiles” displayed on a screen. Each tile pertains to a particular subject matter. Thus, assuming the user has such a tile-based system on his/her device, the user would, for example, touch TRAVEL tile  21  as shown in  FIG. 2A . This then would bring up the display shown in  FIG. 2B  where the user is given a selection of options  22 - 1  through  22 -N. When the user touches AIR tile (preferably a soft button)  22 - 1  the options shown in  FIG. 2C  appear. Here the user is given a choice of the airlines he/she has pre-selected. 
         [0017]    When the user touches tile  23 - 1  all the flights that the user has booked on, for example, AMERICAN™ airlines (AA) are displayed. Touching tile  24 - 1  then yields the screen shown in  FIG. 2E  which then displays the information that has been received from an external source. In this case this information would have come typically from the AA server in the manner discussed above. There could be any amount of information and tiles (or layers) to this information, all controlled by application  30  residing on the user&#39;s device with the updated information coming, from time to time, via messages from various external locations. Note that in  FIG. 2F  the gate and status of the flight have been updated. This update could have come as a result of a request from the user or could have come as a text message from the airline as part of an update service for customers. In any event, the message would have gone first to service center  12  and then via SMS broker  13  to the user&#39;s device where application  30  would have taken the data and placed it in the proper tile. 
         [0018]      FIG. 3  shows one embodiment of a system for controlling messages on a user device. The incoming SMS message would normally be delivered to level  32  of network stack  30  for subsequent display to device user via, for example, display  16  ( FIG. 1 ). The display would be in text or visual form and would then go into the SMS box in text, graphics or video form as is well-known. However, application  31  intercepts the message because that application is registered with the platform to receive certain SMS messages. This protocol varies from device to device based on operating system. SMS or HTTP transports can be used via the side channel process. SMS has the advantage of being a true “push” notification. Application  31  then routes the incoming message, based on the context and content of the data contained in the message to an individual tile, such as to tile  22 - 1  ( FIG. 2B ) or even more specifically to tile  24 - 1  ( FIG. 2D ), as discussed above. 
         [0019]    The SMS message contains envelope information which includes the phone number to which it is destined, and in this case would include additional routing information to route it to application  31  so that the message does not get stored in the message box so the message will not be text formatted. Thus the system takes advantage of a feature that allows SMS messages to be addressed to internal applications. The application address is added at the service center  12 , or if desired could be added by the sender if the application address is made known to the sender. This could, for example, be accomplished by registering the address with the website in advance. 
         [0020]    Another method for doing this would be to run a Simple Mail Transfer Protocol (SMTP) gateway at service center  12 . This would allow application  31  to receive incoming messages in email form. Such email messages could then be parsed to see if they contain certain information, such as the tile ID, etc. This approach would benefit from a fixed format email message. The parsing includes filtering the email messages to see if they contain certain information. The filtered information then would be sent to the device by an SMS message. Second, the formatted SMS message could be sent to the service center for delivery to the particular user device. 
         [0021]      FIG. 4  shows one embodiment of a method, such as method  40 , for controlling applications resident on a mobile device from a remote location. Process  401  determines if a message is incoming to a particular device. If there is a message available, then process  402  determines if the message contains any code or data that identifies the message as one that is to be delivered to a specific application resident on the device and/or delivered customized in a particular manner. If not, then the message is stored in its normal location, for example in SMS layer  32  ( FIG. 3 ) and delivered without modification. 
         [0022]    If the message does contain a “diversion” code or other data that indicates that the message is to be delivered to another location or delivered in a customized manner, then process  404  delivers the incoming message (or other data) accordingly as discussed above, such that a particular user&#39;s tile is customized for a particular application. Customizing could, for example, include one or more of the following: appearance, context, display parameters, including audio, visual, application state change. In some situations, a control command is sent to a user&#39;s tile, for example, using an SMS transport protocol such that the command controls the display parameters and/or the display message instead of actual text being sent to the tile. 
         [0023]    When implemented via computer-executable instructions, various elements of embodiments of the present invention are in essence the software code defining the operations of such various elements. The executable instructions or software code may be obtained from a readable medium (e.g., a hard drive media, optical media, RAM, EPROM, EEPROM, tape media, cartridge media, flash memory, ROM, memory stick, and/or the like). In fact, readable media can include any medium that can store information. 
         [0024]      FIG. 5  illustrates an example computer system  500  adapted according to one embodiment of the present invention. That is, computer system  500  comprises an example system on which embodiments of the present invention may be implemented (such as servers  11 ,  12 , broker  13 , and handheld device  15  of the example implementation of  FIG. 1 ). Central processing unit (CPU)  501  is coupled to system bus  502 . CPU  501  may be any general purpose or specialized purpose CPU. However, the present invention is not restricted by the architecture of CPU  501  as long as CPU  501  supports the inventive operations as described herein. CPU  501  may execute the various logical instructions according to embodiments of the present invention. For example, one or more CPUs, such as CPU  501 , may execute machine-level instructions according to the exemplary operational flows described above in conjunction with  FIG. 4 . 
         [0025]    Computer system  500  also preferably includes random access memory (RAM)  503 , which may be SRAM, DRAM, SDRAM, or the like. In this example, computer system  500  uses RAM  503  to cache messages that have arrived. Computer system  500  preferably includes read-only memory (ROM)  504  which may be PROM, EPROM, EEPROM, or the like. RAM  503  and ROM  504  hold user and system data and programs, as is well known in the art. 
         [0026]    Computer system  500  also preferably includes input/output (I/O) adapter  505 , communications adapter  511 , user interface adapter  508 , and display adapter  509 . I/O adapter  505 , user interface adapter  508 , and/or communications adapter  511  may, in certain embodiments, enable a user to interact with computer system  500  in order to input information, such as media selections. 
         [0027]    I/O adapter  505  preferably connects to storage device(s)  506 , such as one or more of hard drive, compact disc (CD) drive, floppy disk drive, tape drive, etc. to computer system  500 . The storage devices may be utilized when RAM  503  is insufficient for the memory requirements associated with storing media data. Communications adapter  511  is preferably adapted to couple computer system  500  to network  512  (e.g., the Internet, a LAN, a cellular network, etc.). User interface adapter  508  couples user input devices, such as keyboard  513 , pointing device  507 , and microphone  514  and/or output devices, such as speaker(s)  515  to computer system  500 . Display adapter  509  is driven by CPU  501  to control the display on display device  510  to, for example, display the screens shown in  FIGS. 2A-F . 
         [0028]    While  FIG. 5  shows a purpose computer, it should be noted that the exact configuration of a portion of a system according to various embodiments may be slightly different. For example, handheld devices according to one or more embodiments may be any kind of processor-based device, such as a cell phone, a Personal Digital Assistant, a specialized device, and/or the like. Additionally, servers (e.g., servers  11 ,  12  of  FIG. 1 ) and the SMS broker according to one or more embodiments may be any kind of processor-based device capable of sending messages (e.g., email messages, SMS messages, MMS messages), such as a personal computer, a server-type computer, and the like. Moreover, embodiments of the present invention may be implemented on application specific integrated circuits (ASICs) or very large scale integrated (VLSI) circuits. In fact, persons of ordinary skill in the art may utilize any number of suitable structures capable of executing logical operations according to the embodiments of the present invention.
