Description:
BACKGROUND OF THE INVENTION 
       [0001]    Direct contact to mobile system subscribers is an important method for third-party and carrier-based promotions directed to potential customers for additional services and software for their mobile devices (used herein interchangeably with “mobile handset”). Currently, such promotions have certain limitations in practice. Promotional messages are of limited length, are text-only, and are processed and stored in the mobile device&#39;s Short Message Service (SMS) inbox. Richer content associated with the promotions may be referenced using Internet Uniform Resource Locators (URLs), but such links have to be re-typed by the subscriber in order to reach the associated Web pages on the Internet. Similarly, pictures, images or sound may be delivered as content using Multimedia Message Service (MMS). MMS is limited in that MMS provides for immediate content delivery, and is not trigger-based. MMS also provides no feedback mechanism from users, such as in providing interactive or dynamic buttons on a display screen, only providing delivery of content. MIMS is also restricted as to its ability to combine types of content in the display—such as text and a picture—and has no uniform method to put them together in the presentation on a particular device, as it is very dependent on methods adapted to a specific handset and display type. 
         [0002]    One current disadvantage of text-based SMS (or MMS) promotional campaigns is the uncertainty around the delivery time. While most SMS messages are delivered within a matter of seconds, mass SMS campaigns can suffer from traffic constraints at the Short Message Service Center (SMSC), or experience widespread delay because of the subscribers&#39; handsets being turned off, or face time-of-delivery constraints (e.g., shortened period for sending across the U.S. to reach all time zones, 12 p.m. to 6 p.m. EST, reaching users on PST from 9 a.m. to 3 p.m., to avoid sending when subscribers in the spectrum of time zones are not in work hours) because the time zone of receiving handsets is unknown. This can lead to messages being delivered in a very limited range of hours, or at unacceptable hours, or require unwanted padding around the targeted delivery time. 
         [0003]    It would be advantageous, therefore, to be able to deliver content when a subscriber is active on their mobile device (or handset), thus able to immediately view the message or advertising, as well as to target or personalize the content to be delivered based on the subscriber, their activity on the mobile handset, or activity or location of the mobile handset. It would also be advantageous to deliver and store such messages on the mobile handset independent of the trigger events or display of the message content, asynchronously. 
       SUMMARY OF THE INVENTION 
       [0004]    The present invention provides systems and methods for improving information delivery to mobile devices. In an exemplary method a trigger condition (referred to interchangeably as “trigger” or “display condition”) is specified on the mobile device. A message is delivered to the handset via SMS (referred to interchangeably as “content” or “content message”). While the message may be the text-only contents of an SMS message, it is possible to provide for richer content, the SMS message may contain a URL, allowing the mobile device to retrieve and store additional content from a content server. Note that the content message may be comprised of plain text, of rich content with images, layout and text, audio and video, of a source identifier for the content, such as a file, URL, database query result, cache or memory location, or any other means for specifying the content to be retrieved and shown. A specialized form of markup language for specifying content for display on mobile devices called Intelligent Display Markup Language, or IDML, may be used. Finally, when a trigger condition occurs, stored content associated with that trigger is shown on a display of the mobile device. 
         [0005]    In one aspect of the invention, the content comprises information personalized to at least one of the parties included in a call event or information identifying at least one of the parties included in a call event. 
         [0006]    In another aspect of the invention, the displaying of content occurs in response to a trigger based on a user action on the mobile handset. 
         [0007]    In still another aspect of the invention, the content associated with the stored message includes text, graphics, audio, video, a user action, or an interactive user interface object. The content may be used for communication with a subscriber from a carrier (e.g., on account status information, minutes used, etc.) or for advertising purposes. 
         [0008]    In yet another aspect of this invention, the content may be displayed in combination with carrier termination of and timing of an incoming or outgoing call on the mobile handset. In yet another aspect of the invention, generating the display is performed based on at least one of a call initiation event, receive call page event, end-of-call event, or a call termination event. In a related aspect of the invention, the displaying of content occurs in response to a user action, or during a call, or at the end of a call, as in response to a call initiation event, a call page event, an inbound call termination event, or an end-of-call event. In addition, the invention may combine, where desirable, the request, retrieval and display of the content message with the request, retrieval, evaluation and display of caller identification information from other services, of targeted content, or of personalized content. Some triggers will be based on events that can be registered on the mobile device, such as actions that occur when there is an incoming call event. In one example, a trigger can display content from the stored message cache when there is a specific MDN match to an incoming phone number. Other triggers may be polling-based, such as taking a GPS location on a repeating time cycle and determining whether any of the stored content should be displayed based on proximity to the current location of the mobile device. 
         [0009]    In still yet another aspect of the invention, sending the content includes using at least one of a short message service (SMS), a port-directed or application-directed SMS, or a session initiated protocol (SIP) and receiving includes receiving the content message using at least one of a short message service (SMS), a port-directed or application-directed SMS, MMS, or session-initiated protocol (SIP). Other methods for initiating communications with an individual client device or handset from a server may also be used, without limitation. 
         [0010]    These and other examples of the invention will be described in further detail below.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0014]      FIG. 1  illustrates an exemplary system  20  for performing improved information delivery to a mobile device(s)  24  having a processor and memory. An application-directed SMS is sent to the mobile device  24 , and in response content is downloaded from a content server  28  and stored on the mobile device  24 . The content server  28  sends graphical and/or other media content stored in memory  30  to the mobile device  24 , either directly or via an SMSC  26 , based on the received request. The SMSC  26  generates a short message according to a predefined markup language, such as Handheld Device Markup Language (HDML), or such as a more specialized form of markup language for specifying content for display on mobile devices called Intelligent Display Markup Language (IDML). The short message includes content sent from the content server  28 . The short message is sent to the mobile device  24  via the respective carrier (not shown) using SMS. 
         [0015]    The system  20  also includes a wireless network  32  that is in communication with the mobile device(s)  24  and with the content server  28  or other content servers  40  via Internet, other public or private networks (not shown) via a wireless network  32 . For this purpose, network and data communications to the wireless network  32  can be achieved using network services on established cellular networks (without limitation, networks based on wireless standards such as CDMA, GSM, G3), and may also include network communications via mobile access points for Internet, depending on the specific communications hardware installed in the mobile device. 
         [0016]    The predefined markup language is a generalized, extensible markup language (hereinafter “IDML” (Intelligent Display Markup Language)) for creating and displaying promotional content on mobile devices. In one embodiment, an IDML-coded, application-directed SMS (hereinafter “AD-SMS”), which is hidden from the user of the mobile device  24 , serves as the trigger to initiate a server message (from the content server to the mobile device) to the mobile handset telling it how to obtain the content of a graphical advertisement. An application-directed SMS is sent from the SMSC  26  to the mobile device  24 . The SMS includes, at minimum, a link to the content server  28  having a request for media content (i.e., graphical advertisement and markup language). As an alternative, subscriber SMS may be used to transmit the message to the mobile device  24  as well, provided that the subscriber&#39;s SMS client can be instructed not to display the message to the subscriber via the user&#39;s inbox, but rather to store the received message for later display. Once delivered to the mobile device as an SMS message, if more content is designated (e.g., by a URL in the message) the mobile device  24  uses the link to obtain additional content from the content server  28 . 
         [0017]    Storage or memory facilities on the mobile device  24  are used to cache the received IDML content prior to its display on the mobile device  24 . The display of the stored advertisement may occur upon generation or detection of an event, condition or rule evaluated on the handset, e.g., an end-of-call event, thus ensuring a user is available for viewing of the displayed content; or a geographic location or movement determined with reference to GPS location supplied by the handset&#39;s GPS hardware. Displaying of the message content to the subscriber upon an end-of-call event guarantees subscriber presence to the sender of the message, e.g., an advertiser. After a trigger (e.g., an event, condition or rule detected or evaluated on the handset) is experienced or detected at the mobile device  24 , the mobile device  24  displays the content/IDML message stored in the cache on the mobile device and associated with (or alternatively, registered for execution upon) detection of the trigger event or condition. 
         [0018]    In one embodiment, the campaign is triggered by means of a Session-Initiation Protocol (SIP) communication rather than application- or port-directed SMS. Another form of trigger could also be a command signal from an application or network session. 
         [0019]    Three implementations are considered:
       A. Textual content: If the IDML content contains text for display, plus some minor user interface, and thus fits within a 160-character limit, the application located on the mobile device  24  may be executed on a local toolkit on the mobile device  24 , without requiring access to the content server  28 . No URL or other content download is required. Example: a carrier communication to a subscriber such as minute status, minutes of use to a subscriber, payment due notification, or simple advertising message. Note that this type of simple IDML deployment does not preclude the use of the content server  28  on the network.   B. Graphical content: If the IDML content is all graphical, the use of the content server  28  accessed via the wireless network  32  is preferred. The type of display included in the mobile device  24  is identified and used in a query to the content server  28 . Image bits are sent from the content server  28  to the mobile device  24 . The graphics associated with the image bits are then displayed for the appropriate resolution and placement on the mobile device&#39;s display.   C. Mixed content: If the IDML content is mixed text and graphics, a request for a full set of IDML with text and graphics is sent from the content server  28 . For example, an advertisement with the word TOYOTA, a car image, and a “BUY” button. In this case, the IDML file (i.e., SMS message) includes, without limitation: the word TOYOTA as a logo or in an approved text style; an image file, car.jpg; a time and date condition, such as in the form 11:00:00 pm/10-29-2009; a condition setting for launching the message, such as phone-on, call termination, end-of-voice-call, or a specific, designated time or event. The IDML information would be applied on the mobile device  24  to create and display an advertisement/promotion at the designated time or condition, using the designated content.       
 
         [0023]    Without limitation, other triggers that could be applied to launch or to constrain (e.g., set an expiration) on an SMS campaign include events, conditions or rules to be evaluated using the following:
       Time &amp; date   Location of the mobile device  24  (within certain specified cell coverage territories or distance of certain GPS coordinates)   Network or web ( 32 ,  40 ) access from the mobile device  24     Identifying the Mobile Directory Number (MDN) of an incoming or outgoing call (e.g., matching Home Depot advertisement to a call to or from a Home Depot 800 number)   MDN of an SMS message (e.g., in a 411 information SMS containing an MDN)   Identifying the caller (e.g., by name, address, location associated with an MDN)   Personalized information associated with an MDN or caller information   Launching a browser URL at the mobile device  24     Storing a number at the mobile device  24     Detection of movement by noting changes in a GPS location or cell coverage territory (e.g., handset is moving on highway 5 in Tacoma, Wash., so find advertisements from the mall off the highway at a specific exit); or within a distance of a specific GPS location or specific mapped item; or detection of movement of the device using hardware-based movement reporting (e.g., acceleration, direction, velocity and distance covered, perhaps providing time to target location).       
 
         [0034]    In one embodiment, the trigger includes information (e.g., name, address/city/state/location/employer) to aid in identifying at least one of the parties included in a call event. The trigger may also include information personalized to at least one of the parties included in a call event. The personalized information may include some unique characteristic(s) based on metadata known about the person involved (i.e., the viewer of the content delivered to the mobile device). Personalization information may include tracking data, such as web history, purchase history, reading history, etc. This allows the addition of content to a page that is directed to the person viewing the content, but not necessarily identifying the viewer. 
         [0035]    Note that the sending of the message to the mobile device  24 , the retrieval of further content if specified in the message, association of the message with one or more triggers, and display of the content in response to a trigger are asynchronous activities. They may happen in rapid sequence or occur independently, depending on the schedule for provisioning content to the handsets from the network, and depending on triggers arising from actual use of the handset. In another view, a trigger with no content associated with it, or stored content not yet associated with a trigger, are not programmatically bound, so no error condition will occur. There will simply be no available response to that trigger, and no display of stored content, at that time. On certain networks, data and voice activities may occur at the same time (such as GSM networks). On other networks, voice and data activity may not occur at the same time (such as CDMA networks). The present invention does not, however, require that the message or associated content be retrieved during a call, though that may be possible, if appropriate triggers are specified, on those networks in which allow simultaneous voice and data activity on the mobile device. This overcomes the timing and scheduling issues related to SMS message campaigns as presently practiced. 
         [0036]    The present invention may also be used to deliver and to update content for software trials on mobile devices. Methods for trial and expiration messaging are described in U.S. patent application Ser. No. 12/191,904 filed Aug. 14, 2008, which is hereby incorporated by reference. 
         [0037]    While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
