Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The embodiments herein generally relate to wireless communication, and, more particularly, to a method and application for interacting, creating and presenting information to and from mobile communication devices using a rich graphical web-like user interface over SMS as a means of data transfer. 
         [0003]    2. Description of the Related Art 
         [0004]    Presently, several techniques have been developed for connecting to or accessing Internet-based information resources using conventional graphical user interface (GUI) based Internet browser programs. Online search using web-based search engines is evidenced as a significant application of computer networks. Currently, the users of mobile devices, such as wireless phones, pagers, and Personal Digital Assistants (PDAs), can also access Internet search tools to search for content. 
         [0005]    SMS search services allow a user to text a message to a central database/repository/index and receive a reply using text. This information access is primarily performed by submission of one or more keyword messages from the wireless device to a predetermined number serviced by a server. Based on the available information, the server prepares a response that includes information related to the input keyword message. The SMS message is then delivered to the wireless device that requested the information. 
         [0006]    The users of many wireless devices such as cell phones encounter difficulties using search technologies and information access intended for conventional online use. The current methods of finding and using information from the web or an operator portal or partner sites using a cellular phone over SMS is restrictive and largely requires users to follow specified “syntax”—which includes use a prefix of pre-defined keywords (typically, one each for different categories and sub-categories of information). Currently, SMS based information access generally makes limited amount of data accessible to users of the wireless networks. Further, there is no means to access or retrieve search information over SMS via a simple, user-friendly, graphical interface as provided by the web. 
         [0007]    Users rely on the capabilities of mobile phones to stay in touch with their friends and family. In a regular scenario, the users also seek and provide feedback to their friends and family during the decision making process. Currently, no method exists for providing access to a user&#39;s social network comprising of contacts from the phone address book to an information retrieval service. Also, currently no method exists for obtaining the location of a user and transmitting the location by SMS to obtain location-aware information. 
       SUMMARY 
       [0008]    Embodiments herein relate to a method for requesting and obtaining specific information from across the whole web over the cellular short message service using a point and click graphical user interface. Also, provided are systems and an arrangement for encoding and formatting data that includes results, links, ads, actions and other activity to be sent as cellular short messages from the server and at the mobile terminal reassembling, constructing and presenting the received text messages, in accordance, to provide a browsing experience. 
         [0009]    In view of the mentioned, an embodiment herein also provides a method for requesting and obtaining specific information from the Internet over a Short Message Service (SMS) using a Graphical User Interface (GUI). The messages can be rendered in a browser based application or be loaded in an application, developed using various mobile application development technologies such as Symbian, Java ME or Binary Runtime Environment for wireless (BREW). The communication between the server and the application resident on the phone—the client occurs over SMS&#39;, in a single SMS or multiples of SMS for the same information. 
         [0010]    The embodiments disclosed herein further provides systems and arrangement for encoding and formatting data that includes results, links, ads, actions and other elements to be sent as cellular short messages from the server and reassembling, constructing and presenting the received text messages at the mobile terminal to read the search response or continue to browse for desired result. Should there be a need to obtain more info or refine the information from the already obtained information, clicking on the result; similar to on the web would get the linked information. The click is translated into a SMS message and sent to the server. SMS based communication between client and server can be further optimized by using compression. SMSs can also be used to transmit low-resolution graphic elements such as operator logos, image-based ads, icons and the like from the server. The application can be installed on the device. 
         [0011]    The embodiments disclosed herein further provide a method for recording usage, consumption patterns and interaction feedback and subsequently transferring the data to the server. These provide vital feedback about the effectiveness of the search results and can also be used to influence subsequent interactions for the user in particular and other users in general. The device&#39;s address book can be loaded into the application environment, providing an ability to select one or multiple contacts to send the search results, by sending a message to the server including the text and selected contact details. Further, the location of user device by virtue of geographic location or location derived from cellular connectivity can be obtained and transmitted to the server at the time of initiating a search or browse. Furthermore, the movement, usage and consumption patterns including frequented locations, calls and SMS sent in reaction to a received message, addresses saved to a device after viewing the information etc. provide information to bias subsequent results and important feedback about the effectiveness of the search results. Moreover, this metadata can also be used to ascertain the accuracy and correctness of the results provided to the users. This is especially true for SMS-based information access—because there is no direct way to capture and transmit feedback (as captured by various phone-based activities) back to the service.

         [0021]    The embodiments herein disclose a method for providing web like browsing and search over SMS to a client device using a point and click Graphical User Interface (GUI). Referring now to the drawings, and more particularly to  FIGS. 1 through 6 , where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments. 
         [0022]    Embodiments herein disclose a method and system for requesting and obtaining specific information from the Internet or from specific servers over a Short Message Service (SMS) to the user&#39;s cellular device using a point and click Graphical User Interface (GUI). An application, which can be installed on the user device such as a mobile phone, sends the request from the user in the form of a SMS processes the responses received and presents the GUI to the user. The method includes deconstructing and constructing various textual elements that includes results, ads, community-answers, meta-information, and subscription messages in a fashion that provides a web based search and a browsing experience complete with links, graphical elements and interfaces using SMS as a medium of transmission. Subsequent interactions to obtain more information or to refine details are initiated based on a click and sent as a SMS. In the case of an action such as a Call, SMS or save or any other action from the user, these are stored for transfer during subsequent interactions. The app also provides ability for selecting one or multiple contacts from the device&#39;s address book to send search results and seek their input. Further, the location of the client device can be obtained and transmitted to the server at the time of initiating a search or browsing session. 
         [0023]      FIG. 1  illustrates a block diagram depicting the process elements of a SMS based web search and browsing application in accordance with the embodiments herein. The elements include an SMS compatible device  101 , a wireless air interface  102 , an SMS subsystem  103 , the Internet  106  and a server  107 . The SMS subsystem  103  includes a Short Message Service Center (SMSC)  104  and a SMS gateway  105 . The user may demand information or initiate an activity from the application by sending a request to the server, the request can be sent as a SMS from an SMS compatible device  101  over a mobile wireless air interface  102 . The request sent from the device  101  may comprise of a query which contains the entire string that has been entered. The request from the device  101  may also be an identifier to continue a search, which is already in progress on the device  101 . The request from the device  101  may also comprise any one of the following: an indicator for an action event; where the action event may be any event performed by the user like clicking a link in the page presented to the user, a reference to an advertisement, the location of the requesting device  101 , mobile numbers from the contact or address book of the device  101  and a message entered for communication to a third party. The requests sent to the server can be generated by the text entered in an area specified for the text entry, a click on a particular part of the result, a click on an action element, selection of contacts from the contact or address book of the device  101 , or text composed to send to selected contacts from an area specified for entry. The location of the user using the device  101  may also be a part of the query. The wireless air interface  102  transmits information over the air between base stations and mobile units. The SMS is stored in the Short Message Service Center (SMSC)  104 , which is a network element in the mobile telephone network which delivers SMS messages to the destination user when they are available. The SMS Gateway  105  connects to an SMSC  104  on one side and connects to the server  107  on the Internet  106  on the other side. SMS gateway  105  functions as a gateway between the GSM network and the Internet  106 , providing Internet  106  information to mobile—subscribers using SMS messaging. The response to the request sent from the device  101  may comprise of a single SMS or multiple SMS. If the response comprises of multiple SMS, then the SMS may come in non-sequential order. If the response is in the form of multiple SMS, then the SMS received at a specific instant has to be analyzed to determine the position of the SMS in the sequence of SMS that is to be received as part of the response to the query. Once the last SMS in the sequence of SMS is received, the device  101  has to stop listening for further SMS. Also, once the final SMS is received, the device  101  has to reconstruct the response from the plurality of received SMS and present the response to the user in accordance with the structure as intended by the server. The response can be rendered in a browser or in an application such as Symbian, Java ME or BREW in multiple formats like regular plain text; formats based on JavaScript Object Notation or XML encoded results. The interpreted and reconstructed message that is presented to the user comprises of fields like information or suggestions, which the user can use to further refine the query, snippets of results which the user can use to obtain further information, result specific actions which the user can use to fulfill related tasks and advertisements or coupons which can be used by the user. The application renders arrangements for encoding and formatting search results, links, ads, actions and other activities as SMS from the server to the mobile. The messages are reassembled, reconstructed and presented at the mobile terminal providing a browsing experience. The data is encapsulated to provide abstraction while sending, as there are various message types. Further, metadata on messages to be sent from client to server are stored till an opportune time for transmitting the metadata. The metadata includes action taken on a call or SMS, invalid phone numbers, codes, URLs, duration of the call, unresponsive SMS codes, action taken on adds and the like. Snippets of personalization information can also be sent as SMS. The personalization information includes commonly used terms from messages, frequently called contacts, or location recurrences to interpret areas more frequently present. Metadata and snippets can be appended to the user initiated requests for transmission to save transmission costs. The metadata can be appended and sent with search queries, subscription requests or messages to contacts. Server to client communication can be in a single SMS or multiple SMS for same information. The SMSs are received, reconstructed and parsed for making the data comprehensible. The application uses the phone book of the device  101  as the primary social network of the user. 
         [0024]      FIG. 2  illustrates a schematic diagram depicting the network architecture of a SMS based web search and browse application in accordance with an embodiment herein. The network architecture includes a mobile network  201 , a Signaling System No 7 (SS7) network  204  and an IP network  210 . The mobile network  201  includes a mobile station (MS)  202  comprising all user equipment and software needed for communication with a Wireless telephone network. MS  202  refers to a mobile phone or device held by the users in the mobile network. A base transceiver station (BTS)  203  facilitates wireless communication between MS  202  and a network through a base station controller (BSC)  204 . BSC  204  is a combination of device  101  and software used by a base station which enables the base station to register mobile phones in the cell (a geographic area) to perform handoff, call setup and call termination. The SS7 network  205  comprises a Mobile switching Center  206 , Home Location Register (HLR)  207 , Visitor Location Register (VLR)  208 , a Short message service center (SMSC)  104 , a WAP gateway  209 , and the IP network  210  includes a gateway  105 , a partner Call Management System (CMS)  211 , on-deck CMS  212 , Server  107 , and internet  106 . The base stations route the communications to the MSC  206  via a serving BSC  204 . A mobile switching center  206  includes a database for storing location information and the call or SMS details of a mobile terminal. The Home Location Register (HLR)  207  is the main database of permanent subscriber information for a mobile network. The HLR  207  interacts with the MSC  206 , which is a switch used for call control and processing. The third integral element is the Visitor Location Register (VLR)  208  associated to MSC  206  contains all subscriber data required for call handling and mobility management for mobile subscribers currently located in the area controlled by the VLR  208 . VLR  208  maintains temporary user information (such as current location) to manage requests from subscribers who are out of the area covered by their home system. A WAP Gateway  209  is a server through which all wireless (WAP) data is transferred from the device (using WAP requests) to content sites (in WML format) and back to the device  101 . An on-deck and partner call management system (CMS)  211 ,  212  are information storage means in which customers submit information. (either verbally, by e-mail, as Internet data, or via some other form of communication), the call centre deals with that information, and the response is sent back to the user device  101 . The Internet offers a suite of protocols that are beneficial to a call management implementation; this enables coverage of geographically dispersed customers, call agents, or engineers, and provides broad support for multiple data formats. The server  107  is a mobile answer engine which helps to quickly get answers, and acts on them and identifies the really clear answers upfront, or interactively narrows down the search and connects to the SS7 network  205  through a gateway  214 . The World Wide Web (WWW)  213  is a system of interlinked hypertext documents accessed via the Internet. A user can view Web pages that may contain text, images, videos, and other multimedia and navigate between them using hyperlinks. The result based actions such as call, SMS, save, action responses as call success and duration, call failure and reason, invalid links, SMS success , SMS failure, actions taken on ads, and the like are stored for appropriate time of transmission. The feature provides ability for selecting one or more contacts to send a result and also sending messages to multiple selected contacts. Further, the location of the device  101  is obtained and transmitted to the server at the time of initiating communication. Location of the client can be obtained by virtue of the cell id and location area code or base ID in GSM and CDMA phones respectively. If the device  101  has GPS, then the location of the device  101  can also be obtained by using the latitude and longitude of the device  101 . 
         [0025]      FIG. 3  illustrates a logical diagram depicting the system architecture of a SMS based web search and browse application in accordance with an embodiment herein. The architecture includes an Input/Output (I/O) module  301 , a presentation module  302  and a device module  303 . The I/O module  301  includes messages involved in client to server communication such as alerts  304 , responses  305 , updates  306 , Ads  307 , metadata  308 , requests  309 , to encode  310 , awaken  311  and reconstruct  312  the I/O. The result based actions meant for appropriate time of transmission are stored in storage  313 . The presentation module  302  includes a parser/translation engine  314  and user interfaces  315 . The device module  303  includes device APIs  316  which interact with contact details  317 , subscriber location  318 , logs  319  and storage  313 . The metadata  305  and requests  309  are send as messages from the client to the server. Server to client communication can be in single SMS or multiples of SMS for the same information. The messages are received, reconstructed and parsed such that the entire data is comprehensible. Alerts  303  and subscription messages automatically wake up the client when server sends updates  306  and the messages are subsequently presented in correct context. Application awakening  311  and message interception can be based on SMS push registry, Binary runtime environment for wireless (BREW) directed SMS, or source dependent awakening. Server can also send additional information that can be cached on the phone for subsequent use including ads  307 , updates  306  and the like. 
         [0026]      FIG. 4  illustrates a schematic diagram depicting the structure of a SMS used for web search and browse in accordance with the embodiments herein. An SMS comprises of header  401  and data  402 . Header  401  is information placed at the beginning of a block of text being transmitted. Data  403  refers to a collection of organized information, usually the search results, ads, meta information such as popular searches or other information within a computer system, or a set of premises. Data  403  can also comprise of extra information that can be cached on the phone for subsequent use. This includes ads, results, updates as well as metadata such as “popular searches” and other trends. Data  403  may consist of numbers, words, special characters or even images encoded in the form of alphabets, numbers or special characters, particularly as observations of a set of variables. The data field  402  further comprises fields of notation begin  403 , identifier  404 , notation data unit  405  and notation end  406 . The notation begin field  403  indicates the start of a particular piece of information along with the representation of the kind of data unit that is being transmitted. Multiple data units can form part of the same SMS. Identifier  404  is a compact string of characters used to identify and relate the set of messages that need to be packaged and interpreted together from the multiples of SMS of a resource being transmitted. The main purpose of the identifier  402  is to enable interaction with representations of the resource over a network, typically the World Wide Web, using specific protocols. SMS based communication between client and server can be optimized by using compression. SMS can also be used to transmit low-resolution graphic elements including operator logos, image-based ads, icons etc from the server. 
         [0027]      FIG. 5  illustrates a flow diagram depicting a method of requesting and obtaining information using a SMS based web search and browse application in accordance with an embodiment herein. The application is loaded ( 501 ) by clicking on the application icon on the device. The application initiation process begins ( 502 ) by running a background process that communicates with various processes on the device. The location information availability of the client or the connection details of the client is determined ( 503 ) and past obtained information, other details and identifiers to the information are retrieved ( 504 ). Further, recent and popular context terms are loaded ( 505 ) and the corresponding links if any determined. Then recently received alerts or messages and their links to the messages are retrieved ( 506 ) and then advertisements with actions are loaded ( 507 ). Further, the user interface with text box and information is formatted with links is presented ( 508 ) in a graphical point and click interface. Thereafter, the initiation process is ended ( 509 ) and the application waits for user interaction. 
         [0028]    Obtaining meta information, updates, ads and other periodic information detailed above occurs by the process of messages being pushed by the server, simulating an always on data connection. As the information gets updated in the background, no user intervention is required for it. The arrangement for all the above further includes methods, handled within the application that comprises the steps of receiving the information in a single or multiples of SMS, processing the SMS and determining the position of the message if multiples of messages received, and in the course of processing the SMS and determining the last message. On receipt of last message, ending listening for the current chain of SMS, reconstruction of the entire information, inferring the type of the message and storing the information on the device  101 . The device  101  further stores past searches performed or information retrieved by the user. 
         [0029]      FIG. 6  is a schematic diagram depicting the graphical user interface for providing search and browsing results over SMS to a device  101  in accordance with an embodiment herein. The interface permits SMS-based search and also light-weight browsing and is presented using a user application, existing on the device  101 . The user application on invocation performs the composition and rendering of a main interface that comprises of information on popular content or recently added or updated content, with their terms and further links to the content. The content could be available on the internet or in a closed environment on particular mobile operator or content provider server. The application also renders popular content and added or updated content obtained from the internet or within the confines of a mobile operator or content provider systems with the actual text, their respective sources and the links to view detailed information wherever possible. The application also renders advertisement messages with their text the possible associated interaction attributes as activities to exercise action on them. The graphical user interface  600  of the application includes a block  601  where the user can provide the terms to obtain information or keywords to search. The interface generally includes the popular topics searched, past search data, new alerts and messages such as new deals on apparels, foods, and other offers, new jokes, top movies, product reviews and the like.
