With the explosion of the Internet as a new indispensable worldwide medium, the web is becoming an integral part of our daily personal and working lives. Electronic commerce continues to see phenomenal growth, but so far most e-commerce developments have involved wired infrastructures.
In this new knowledge economy that puts increased demands on every individual's time, mobility will become an essential, relevant and important tool. While the Internet allows real-time communication and transactions, online accessibility has been restricted to PCs. With the advancement of wireless network technologies, electronic commerce through the Internet has extended itself to incorporate new business opportunities in the arena of mobile commerce (m-commerce).
In the field of m-commerce, there are significant restrictions on the efficiency and variety of m-commerce transactions that are available. Current technology is either limited to off-line payment or to restricted merchant specific on-line mobile payment through a mobile phone using a smart card, wherein the mobile phone must contain a dual slot smart card reader. Other m-commerce payment processes include dialing a premium rate number, e.g., 900-number, which has a call charge equivalent to the product price, dialing a prefix plus a premium rate number to indicate that the product should be charged to a different number for billing, and developing a pre-standing agreement for credit card payments, wherein a PIN has to be entered at the time of purchase to validate the user. These payment solutions offer no variety in payment methods and are limited to participating vendors, e.g., off-line vending machines. Further, m-commerce payment limitations affect mobile shopping, mobile retailing, and mobile ticketing. While electronic shopping, retailing, and ticketing have been available for some time, there are additional steps required to complete a mobile transaction. On-line mobile payments, shopping, retailing, ticketing, etc., require language recognition and or conversion in order to complete transactions with electronic merchants and payment authorization systems. Consequently, there is a need for a system and method of performing mobile commerce which facilitates interaction between mobile and electronic components which utilize differing protocols and languages.

The present invention is an enabling product that facilitates implementation of an m-commerce business solution. According to an embodiment of the present invention an m-commerce solution includes: a content provider or merchant site (e.g., an eMall, financial institution, etc.) (hereafter “merchant site”) providing the products and goods to be purchased; a payment system allowing online authorization of funds to purchase the goods; and a wireless network for all customer interactions. Preferred embodiments of the present invention perform at least one of the following three functions: 1) protocol conversions; 2) customer information reposing, and 3) payment authorization system interfacing.
The protocol conversion aspect of the present invention, according to at least one embodiment, converts content (e.g., messages) developed in one of a multitude of languages, such as, HTML (hyper text mark-up language), compact HTML (CHTML), or XML (extensible mark-up language) to an appropriate language for a receiving device, such as, Wireless Markup Language (WML), HDML (handheld device mark-up language or UP Browser), CHTML and vice versa. The customer information repository aspect of the present invention, according to at least one embodiment, contains various customer information such as a preferred shipping address; a list of credit cards, debit cards, and/or other payment vehicles, including, but not limited to, credit card types and card numbers that may be used for a purchase transaction; and a customer identifier, such as, a mobile device subscriber identification (“ID”) number.
The payment authorization system interface aspect of the present invention, according to one embodiment, provides interface logic with a payment authorization system to facilitate the authorization of a commerce transaction.
More particularly, an embodiment of the present invention is directed to a mobile commerce system that comprises at least one mobile device for transmitting and receiving data in a first language, a platform for transmitting and receiving data in the first language and data in a second language, at least one merchant site for transmitting and receiving data in the second language, and a payment authorization system for transmitting and receiving data in the second language.
Another embodiment of the present invention includes a method for conducting mobile commerce. This method comprises: transmitting in a first language a request message for merchant website information from a mobile device; receiving the request message in the first language at a platform and identifying the first language; translating the request message at the platform from the first language to a second language that is recognizable by a merchant website; communicating the translated request message in the second language from the platform to the merchant website; receiving at the platform the requested merchant website information from the merchant website in the second language; recognizing the second language at the platform; parsing the requested merchant website information in the second language into translatable pieces; translating the translatable pieces of the requested website information into the first language so as to form a reply message containing the requested merchant website information in the first language; and transmitting the reply message to the mobile device.
These and other aspects and embodiments of the present invention are set forth below with details.
For purposes of this disclosure, the terms mobile commerce (m-commerce), mobile electronic commerce, and wireless electronic commerce may be used interchangeably. The term m-commerce represents a subset of all e-commerce transactions, both in the business-to-business (B2B) and the business-to-consumer (B2C) area.
The present invention provides a mobile system for facilitating mobile commerce among multiple parties. In the preferred embodiments of the present invention, the mobile system performs at least one, and preferably all three of the following three functions: 1) protocol conversions; 2) customer information reposing, and 3) payment authorization system interfacing. The mobile system achieves these functions using at least one of the following components: a state manager; parsing agents for parsing e.g., XML and HTML; translation agents for translating to and from e.g., WAP, CHTML and HDML; communication agents for communicating between e.g., HTTP (HyperText Transfer Protocol) and HTTPS (Secure HyperText Transfer Protocol); server and database configurations; and settlement systems.
In facilitating protocol conversions, the mobile system enables the delivery of a single sourced web content to a wide range of wireless devices or mobile devices (hereafter “mobile devices”) and vice versa. The mobile system is capable of presenting a transmission from a mobile device to participating Web servers as a standard Web client, thus performing a gateway/protocol conversion function between a mobile device and a merchant site or sites. To accomplish this, the mobile system allows users of mobile devices to communicate through the web with merchant site applications running on web servers using, for example, HTTP or HTTPS protocols. According to the embodiments of the present invention, the mobile system dynamically performs the required translation between the merchant site webpages encoded in, for example, HTML, CHTML, XHTML or XML to WML, CHTML or HDML for the mobile device.
According to further embodiments of the present invention, the mobile system also manages the state and associated context information between the merchant site and the associated mobile device(s). This information includes, for example, HTTP session state, cookies, links and/or universal resource locators (URLs) referenced during the session and control information for each HTML page. As most mobile devices currently do not support cookies, the mobile system manages the persistent store associated with each cookie on behalf of the mobile device.
According to embodiments of the present invention, the mobile system is integratable with existing merchant sites, such as, an eMall for m-commerce applications or Citibank Direct Access in the case of banking transactions. The merchant site operations experience very little interruption. For example, the merchant sites continue to receive and transmit HTTP and HTTPS messages for incoming requests and continue to dictate screen flow.
As described further below, the mobile system offers a scalable architecture, allowing concurrent access by mobile users to HTTP and HTTPS pages served on merchant sites. In an embodiment of the present invention, the scalable architecture is developed on Windows 2000 using COM+ services and at least one Microsoft SQL Server in order to support high numbers of concurrent mobile users on a single server, and includes the ability to add more servers as business requirements dictate. The mobile system can use standards such as COM (Component Object Model), SSL (Secure Sockets Layer), HTTP, WAP, HDML, CHTML, XML and HTML. Using SSL communications, every transmission between the client and the server is encrypted.

In order to perform merchant site format translation to mobile device format, the mobile system insures that all communication between the merchant site and the mobile device occurs through the mobile system architecture. Using the mobile system's link/URL management feature, this is insured by dynamically converting all Hyperlink (Href) information on the page published by the merchant site to the URL (universal resource locator) of the mobile system (e.g., URL of the company offering the services of the mobile system). The mobile system saves the original, unconverted URLs within a relational database 35. In this manner, all user interaction from the mobile device is intercepted and interpreted by the mobile system prior to being forwarded to the merchant site.
In another feature of the present invention, since most mobile devices currently do not provide support for cookies, the state manager component manages the persistent store associated with each cookie on behalf of the mobile device. For instance, if the target HTML page on the merchant site writes a cookie, that cookie is stored on the mobile system on behalf of the mobile device and is returned only when the response is posted to the appropriate merchant site. The mobile system's cookie management insures integrity of the cookies by insuring proper domain association as well as lifetime expectancy.
The parsing agents 25 of
According to an embodiment of the present invention, an exemplary interaction between a merchant site and a mobile device through the mobile system for displaying a single webpage is as follows. Referring to
After retrieving the session information, the state manager 15 engages the communication agent 30, S5. An HTTP or HTTPS Post is performed to the merchant site 40 based on existing link (e.g., HREF) information in the state tables (See Table 1) S6. The merchant site webpage response is returned to the communication agent S7. Based on the webpage content, the communication agent 30 determines the encoding thereof, e.g., HTML or XML, and engages through the state manager 15, the appropriate parsing agent 25 to parse the response S8a, S8b. For each item parsed in the merchant site webpage, the parsing agent 25, in conjunction with the translation agent 20, dynamically performs the associated translation to the predetermined mobile device format S9. This step is repeated until the entire merchant site webpage has been parsed and translated to the predetermined mobile device format. For example, from HTML to WML for a WAP mobile device. All session information is saved to the persistent store, i.e., relational database, on behalf of this mobile device under a mobile device ID (e.g., alphanumeric identifier) S10. As described above with reference to S3, this session information is later retrievable during the next interaction between the mobile device 45 and the merchant site 40. The translated response is returned to the ASP thread S11 through an HTTP response and on to the mobile device 45 through the phone gateway 50, S12.

b illustrates the enhanced scalability available with the mobile system of the present invention. Although the mobile system is capable of handling a high number of concurrent mobile users 45a-45c on a single server, the mobile system includes the ability to add more servers as business requirements dictate. This enhanced scalability is optimized through the use of services such as, Microsoft's COM+services. The mobile system supports a multi-tiered architecture, separating the application logic and data components. This allows for greater scalability based on the projected requirements. In
According to an embodiment of the present invention, the mobile system is designed to provide hosting support for multiple entities (e.g., businesses) within the company providing the mobile system, while utilizing the same physical hardware. For example, hosting multiple mobile system URLs on the same physical server provides the foundation for this capability. The persistent store associated with each business within the company is preserved in different database tables and is indexed by the ID of the current entity being serviced for each mobile device interaction.
Referring to
After retrieving the session information, the state manager 15 engages the communication agent 30, S24. An HTTP or HTTPS Post is performed to the merchant site 40 based on existing link (HREF) information in the state tables (See Table 1) S25. The merchant site response (e.g., Webpage) is returned to the communication agent S26. Based on the response content, the communication agent 30 determines the encoding thereof, e.g., HTML or XML, and engages through the state manager 15, the appropriate parsing agent 25 to parse the response S27a, S27b. For each item parsed in the response, the parsing agent 25, in conjunction with the translation agent 20, dynamically performs the associated translation to the predetermined mobile device format S28. This step is repeated until the entire response has been parsed and translated to the predetermined mobile device format. For example, from HTML to WML for a WAP mobile device. All session information is saved to the appropriate persistent store, i.e., relational database 35a, 35b, on behalf of this mobile device using the mobile device identification number for the business ID S29. As described above with reference to S22, this session information is later retrievable during the next interaction between the mobile device 45a, 45b and the merchant site 40. The translated response is returned to the ASP thread S30 through an HTTP response and on to the mobile device 45a, 45b through the phone gateway 50a, 50b, S31.
As described generally above with reference to the mobile system components, protocol converters are used within the mobile system in order to reformat received content or messages (hereafter “messages”). The reformatted messages can then be sent from and to different types of mobile devices. This enables content providers to deliver a single marked-up message to a wide range of wireless devices. The phrase “mobile device” is not intended to be limited to telephones, but rather this phrase encompasses all mobile or portable communication devices which communicate over wireless phone lines. The protocol converter converts website messages (e.g., from merchants) to a specific mobile device message format and vice versa. The protocol converter converts, by way of non-limiting example, content developed in HTML, Compact HTML, or XML to Wireless Markup Language (WML), HDML (UP Browser), CHTML or Imode. Any source message, e.g., message received, can be converted to any of the possible target message formats, target messages being the messages that are being sent.
In a first protocol conversion example, existing source HTML messages are initially reformatted in order to support XML specifications. Referring to
The customer information repository is stored and provided in order to minimize the amount of input that a customer has to enter while conducting an m-commerce transaction. Minimizing the amount of customer input increases the speed and simplicity of m-commerce transactions, which is very much in keeping with the fundamental idea of mobile commerce. In addition, wireless phone devices are not generally equipped with a robust keypad interface. Therefore, it is important to minimize the amount of information collected from a customer during a transaction. The information stored within the customer information repository, includes, but is not limited to, billing addresses, shipping addresses, a list of credit cards or payment vehicles that may be used for a purchase transaction and a mobile device subscriber ID. The information is gathered during one of multiple m-commerce service registration processes that are available. For example, the information can be gathered during the customer self-registration process through a web site facility or via staff-assisted registration. Alternatively, customer registration may be accomplished via a batch facility wherein a batch file containing registration information for all customers is updated and accessed. The information is linked to the customers mobile device ID (e.g., number, alphanumeric) so at a later time when the customer chooses to make a transaction, the system of the present invention is able to access the customers' personal information. Instead of requiring, for example, a customer to enter the credit card number of the credit card they would like to use during a transaction, the system will prompt the customer to choose which of their pre-registered credit cards they would like to use. Additional required customer enrollment fields can be added based on individual business requirements.
Payment gateways or settlement systems are provided to manage the interface with the payment authorization systems. The payment gateway generates payment authorization requests to the payment engine and then returns the results of the authorization request to the merchant for order fulfillment. The present invention can support a variety of interfaces to the payment authorization system, including, but not limited to, an HTTP(s) post to a secure website payment system or a Microsoft COM-based interface to an ECS payment engine and the CitiConnect system used by, for example, the Global Cash and Trade organization.
Additionally, the mobile system of the present invention may be integrated and can co-reside in business installations with other m-commerce related services, such as the financial transaction and event notification systems (hereinafter “notification system”) described in U.S. patent application Ser. No. 09/832,863, entitled “METHOD AND SYSTEM FOR NOTIFYING CUSTOMERS OF TRANSACTION OPPORTUNITIES” the entirety of which is incorporated herein by reference. The notification system, in conjunction with the mobile system, provide, by way of example, the following additional services: specific account notifications, such as past-due-date reminders, overdrafts, credit limits, specific credit charges (e.g., single amount charges, location charges), credit fraud warnings (e.g., based on unfamiliar pattern of charges, location of charges, amount of charges) direct deposits (e.g., of salary, dividend, etc.), balance, credit card due dates, automatic bill payments, check clearing alert and ATM withdrawals; shipment of goods notification; stock price notifications, and the like. This list is not intended to be exhaustive, but merely exemplary.
The following embodiments of the present invention disclose non-limiting specific, exemplary configurations of the present invention which incorporate some or all of the various aspects of the invention described above.
Referring to
Further to this embodiment, the WAP enabled phone 45, communicates directly with a telephone company, i.e., the wireless carrier who offers the service, which we refer to herein as a phone gateway 50. In this embodiment, the phone gateway 50 is comprised of a Short Message Service Controller (SMSC) 47, a WAP gateway 48, and a specialty server (i.e., BMG server) 49. Data information is carried over the airwaves via, for example, a GSM (Global System for Mobile Communications) network 46, which uses narrowband time division multiple access (TDMA), allowing eight simultaneous calls on the same radio frequency. In a first information configuration of this particular embodiment, data information is collected from the WAP phone 45 by the phone gateway 50 which is connected to the mobile system 10. The data information is communicated between the phone gateway and the mobile system via at least one of a group of first line networks 51 including, leased lines, dial-up, and Internet which support TCP/IP (Transmission Control Protocol/Internet Protocol), HTTP, WML, etc.
The mobile system 10 communicates with both merchant sites 40 and payment gateways 75 through at least one of a group of second line networks 61 including, but not limited to, dial-up and Internet which support TCP/IP, HTTPS, HTML and XML. By way of example, the merchant, Ticket Pro, maintains an inventory of concerts and sporting events, as well as, seating arrangements, costs, etc. The mobile system 10 is in electronic communication with the Ticket Pro website either directly, or through a merchant webpage provider such as eMall 40. In this particular embodiment, the messages provided by the eMall are formatted so as to be recognized and read by the phone authorization system and consequently, the WAP phone 45, without the need for any type of protocol conversion by the mobile system 10. As discussed further herein, in alternative embodiments of the present invention, there is a need for protocol conversion by the mobile system in order to facilitate communication between the merchant site and the mobile device.
Further to the embodiment illustrated in
Another aspect of the embodiment illustrated in
According to this particular embodiment of the invention, customers register with an account set-up and maintenance portion of the payment authorization system 76 in order to access the m-commerce configuration. Similarly, customers register directly with the notification system 90 in order to participate in the alert portion of the enabling platform 5. Registration is performed online, e.g., over the Internet 80 via a personal computer 85 or other acceptable device. During this registration process, the customer repository information, described above, is obtained and stored in a relational database of the mobile system 10.
In yet a further aspect of the embodiment illustrated in
The settlement system employs, for example, Secure Socket Layer (SSL) technology with standard Public Key Infrastructure (PKI) and digital signatures for each message exchange, providing a highly secure transaction processing environment. A user registers with the settlement service 95 prior to conducting m-commerce transactions. Registration may be provided through the payment authorization system 75. As discussed further below, the payment authorization system 75 and the settlement service 95 may be provided by the same host (e.g., Citibank) or as in this embodiment, these services may be offered by different hosts, but are linked for the purposes of the m-commerce transactions described herein. Depending on the payment authorization system configuration 75, the messages communicated between the payment authorization system 75 and the settlement system 95 are formatted differently. For example, in this embodiment and the embodiment described below with reference to
Referring to
In this particular embodiment, at least three different phone companies, each of which uses a different language for its customers, are utilized. Further, while the entire implementation, including information from all three phone companies, could be accomplished using one mobile system server 60 (see
As previously discussed, the embodiment described with reference to
Further, with respect to
In the embodiments described above, because all the wireless protocols being used are not considered secure, leased lines may be used, where available, so that data coming from each of the phone gateways is encrypted. In these configurations, the servers 60a-60c decrypt all incoming data before performing the appropriate protocol conversion and encrypt all outgoing data after performing the appropriate protocol conversion. Any encryption technique known to one of skill in the art may be used, including but not limited to, secure socket layer (SSL) or public/private key (PKI) encryption.
