Abstract:
Systems and methods for automated retrieval of digital content from vendors upon occurrence of a 411 call event from a mobile device. In an example method, a message is sent from the mobile device based on the detected 411 call event. A server receives the sent message, compiles associated digital content based on information in the received message, and sends the digital content to the mobile device. The mobile device outputs/displays at least a portion of the received digital content to the user soon after the occurrence of the 411 call event.

Description:
FIELD OF THE INVENTION 
     This invention relates generally to 411 calls and, more specifically, to enhanced information delivery based on a 411 call event. 
     BACKGROUND OF THE INVENTION 
     When a 411 operator or Directory Assistance (DA) is dialed on a wireless handset, carriers or their 411 service providers (DAs) can optionally provide a Short Message Service (SMS) message to the mobile handset over an SMS network from the operator&#39;s station containing the requested caller information, mapping information, etc. to supplement the expected oral delivery and connection of the caller to the requested number. For example, the SMS message may contain the information “John Doe, 206-555-1212” embedded in an SMS message confirmation of the inquiry. 
     While useful, the method of delivering information to the subscriber via basic SMS is constrained by technical limitations of the SMS. Only text information may be sent, which is limited to 160-characters. Therefore, the prior capabilities have some limitations. 
     SUMMARY OF THE INVENTION 
     The present invention initiates a server lookup after a 411 call in order to display the listing information in a graphical format and provide additional information. The server lookup may be initiated by a short message service (SMS), by an application-directed SMS (AD-SMS), which is hidden from the subscriber, or by the mobile device that initiated the call by detecting that “411” has been entered on the keypad. 
     An example method detects an occurrence of a 411 call event from a mobile device, sends a message from the mobile device based on the detected 411 call event, receives digital content at the mobile device from a server based on the sent message, and displays at least a portion of the received digital content on the mobile device. 
     In one aspect of the invention, the digital content includes at least one of textual and graphical content. The textual and graphical content includes a coupon, operational hours information, a map image, website information or other interactive content.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       FIG. 1  illustrates a wireless/cellular system  20  that includes one of many mobile handsets  30 , wireless/cellular nodes (also known as Mobile Switching Centers or MSCs)  46 , a wireless network  44 , a 411 operator or Directory Assistance center (DA)  38 , a Messaging Application Server (MAS)  52 , one or more content providers  54  and a Short Message Service Center (SMSC)  50 . The handset  30  automatically determines if an incoming short message service (SMS) message is received from the DA  38 . If the SMS message is from the DA  38 , the handset  30  requests the MAS  52  to send content from the one or more content providers  54 . The retrieved content is then sent to the handset  30  via the SMS message (the SMSC  50 ). 
     In one embodiment, the content providers  54  are in data communication with the MAS  52  via a network  58 , such as a public or private data network. The MAS  52 , the content providers  54 , the SMSC  50  and the DA  38  are preferably computer-based systems that automatically perform some or all of the processes described herein. In another embodiment, the information associated with the content providers  54  is previously stored in databases associated with the MAS  52 . 
     As shown in  FIG. 2 , an example of the mobile handset  30  includes a processor  60 , output devices  62  (display(s) and/or speaker(s)), a user interface  64 , a communication device  66 , and memory  68 . An application  72  is stored in the memory  68 . When an SMS message is received, the processor  60  which is running the application  72  determines if the received SMS message is received from the DA  38  (e.g., formatted sender address information associated with the DA  38 ), then outputs an image and/or sound to the user of the handset  30 . The mobile handset  30  may be a cell phone, mobile device, VoIP device, portable data assistant (PDA), or any comparable device. 
       FIG. 3  shows an example process  100  performed by the handset  30 . First at a block  104 , the user/subscriber initiates a 411 query with an operator at the DA  38 . The 411 query includes a request for a phone number. At a block  106  the operator answers the query by finding the requested number (MDN), presents the findings to the subscriber (if multiple numbers are found), makes the connection, and sends an SMS message containing the requested MDN and/or associated listing information to the MAS  52  and/or the mobile handset  30 . Options for further information are selected (or pre-configured). At a block  112 , the MAS  52  obtains enhanced message information by retrieving the enhanced message information from the content provider  54  associated with the MDN or by using the XML containing the requested MDN and listing information. Next at a block  114 , the MAS  52  sends a hidden SMS message using an application-directed (on code division multiplexing (CDMA)) or a port-directed (on GSM) SMS to the mobile device  30 . When the SMS message containing the requested information is received by the subscriber, the format of 411 information is detected by the application  72  on the mobile handset  30 , see decision block  118 . If the SMS message is determined to include content associated with a 411 query, the processor  60  outputs an image on the display  62 , see block  122 . 
     In one embodiment, a popup display appears immediately with mixed text and graphics containing the information from the 411 listing supplemented by additional content, for example, items for subscriber interaction, containing coupons, location and map information, website information, and/or call-back information. Certain or all of the received 411 information and/or the enhanced, additional content received from the server may be store in the mobile device. For example, certain received 411 information pertaining to contact information may be stored in the caller directory. Certain of the enhanced, additional contact may also be stored in and subsequently accessed by the mobile device. Such storage may be done by automatically displaying the received 411 information to the subscriber along with an option to accept and store the received caller information on the mobile device, or to reject and discard it. In another embodiment the received 411 information is automatically displayed and stored in the mobile device. 
     If the received SMS message is not 411 formatted, then the SMS message is processed and presented, see block  120 . 
     An advantage of the present invention is that the listing information is no longer limited to 160-characters. Moreover, the information displayed to the subscriber may contain additional information like hours of operation, payment options (i.e. Visa, Mastercard, Discovery), restaurant ratings, etc. The services described herein can be managed by the mobile carrier itself, contracted DA services, messaging application services, such as those offered by Cequint, Inc., or combinations thereof. Depending on the subscriber&#39;s choices, a carrier supported SMS service can direct the messages for delivery via SMS as contact information, as location and mapping information (for example, to interact with applications such as Networks in Motion&#39;s Navigator product), or as interactive content for advertising and retail services (for example, as provided by Cequint, Inc.&#39;s IDML server). 
     The present invention allows for immediate delivery of 411 information and at the same time, without further subscriber action required, integrates seamlessly a variety of messages to the mobile subscriber. Graphical content may be included to show a picture of the business related to the listing, logos, and/or coupon offers. The content may support the integration of both ecommerce methods (e.g., Google AdSense, Amazon 1-click, EBay, etc.) and traditional retail advertising and sales (e.g., ad and brand placements, 800 numbers, etc.) 
     The present invention also allows integration of coupons and promotions, including software trials, with the display provided, and to engage in both order and payment directly via software communicating with the mobile device (e.g., PayPal or secured credit card transaction). 
     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.
