Wireless Application Service Provider System

The present invention relates to a wireless application service provider (W-ASP) system, and more specifically, to a legacy system that an enterprise has in addition to information existing on a web or a database. It can provide a function that can provide the information in the same form, and by providing a client independent of the content, separate from the increase or change of content in the existing client / server (hereinafter referred to as C / S) system It does not require versioning, includes original technology that provides a component-based user interface provided by the device, rather than simple browsing, and allows the administrator to provide unique and innovative features for dynamic user screen composition. Regarding wireless application service provider system will be.

In general, wireless ASP, which provides outsourcing services wirelessly for various applications and data according to the development of electronic commerce, mobile communication terminal, wireless Internet, etc., stands out in terms of information service outsourcing of enterprises. The wireless ASP acquires information from information providers such as companies and information companies, processes it, and uses mobile communication terminals such as PDAs (personal digital assistants), mobile phones, two-way pagers, laptops, and pocket computers to information consumers through wireless network operators. It is an information technology to maximize the information effect of a company by effectively providing application and data service. The wireless ASP is still in its infancy in terms of technology and market. Therefore, there are various opinions because there is no clear division of the scope of the wireless ASP. Table 1 below shows the wireless ASP service classification of Cahners IN-STAT, which relatively clearly classifies the range of the wireless ASP.

Scope of Wireless ASP Services Data transformation service The transform service provides a transform service function for content and data to provide existing wired web content using a wireless network. Wireless Application Service The wireless application service is a service that provides information and data related to an application using a wireless network according to a specific contract. Wireless content services It is a service that provides information on the existing Internet through a wireless network. Wireless Infrastructure Technology and Services It is a service that provides infrastructure technology for consulting and after-service as well as building software and hardware systems to wireless network providers and content providers.

On the other hand, the wireless ASP is largely composed of the service and system sectors.

The service sector is divided into back service and front service. The back service is part of building and managing solutions such as application development, system construction and integration, customization, consulting, security service, network management, and data center construction for the effective provision of applications and information. In addition, the front service provides services for application-related functions in direct connection with actual users such as customer management and support, and billing.

The system division consists of data centers, gateways, networks, and mobile communication terminals. Data centers are an integral part of application services that run applications and store data, including the enterprise data center and the service provider's data center. The gateway is a part that connects the data center and the network and performs data conversion according to the protocol so that the network can receive the data center information. The network conveys the information in the data center to the user and the user's request to the data center and gateway. Finally, mobile communication terminals are mobile media, PDAs, laptops, and the like, which are actual media users receiving application services.

The front service is a system administrator, software developer, network administrator, etc., which provides various services so that users can effectively access applications and data in the data center by using mobile communication terminals such as mobile phones and PDAs.

The back service is divided into building and managing data centers and building and managing gateways. In terms of building a data center, applications and databases can be built using packaged applications and built on their own using system development tools. Sybase and Oracle are two major vendors that provide such system construction services.

Gateway construction and management are the areas where data centers and networks are effectively linked to maximize the effectiveness of the system. Cvista and Epresence are the representative vendors that provide such services.

The data center is the core of application service provision, and the main tasks of application services such as application execution and management are performed here. It has a corporate data center, and a service provider data center, which is the part that manages corporate data, and the service provider data center is the data center that provides the capabilities to provide wireless application services. Dataroam and Wicities are two of the leading vendors of data center services focused on wireless ASPs.

Acting as a middleware for data centers and networks, the gateway provides security and carrier management. As the gateway is an essential part of ASP for users to support application services using a mobile communication terminal, many vendors provide gateway related services. Major vendors of gateway-related services include Aether Systems and Oracle Mobile. Aether Systems, which provides system design, development, integration and support services for application outsourcing, provides gateway solutions in its data centers in Maryland, USA. Oracle Mobile, Oracle's subsidiary, provides gateway testing, technical support, and monitoring capabilities in its data centers.

A network is a system that directly provides information to and receives information from a user's mobile terminal. Since a user's terminal is wireless, a wireless ASP performs many functions in terms of stability and connectivity compared to a wired ASP.

It is recognized that mobile communication terminals are not included in the wireless ASP system so far, so few wireless ASP vendors provide terminals. Currently, vendors providing mobile communication terminals include Cable Wireless (Compaq terminal) and Nextel (Motorola terminal).

On the other hand, the greatest development of information and communication since the 1990s has occurred in the Internet and mobile communication. With the development of the Internet, users can obtain various information such as text and multimedia from a server using a web browser, etc., and with the development of mobile communication, users can exchange information effectively regardless of the place. Wireless ASP is a combination of these two technologies that allows users to effectively leverage enterprise applications and information wherever they are.

However, there are many problems in combining the Internet and mobile communication. The access technologies of the two technologies are different, the network protocols are different, and the access media and browser standards are different. For example, the Internet uses an internet protocol (IP) in terms of network protocols, while mobile communication uses protocols such as TDMA (USA), GSM (Europe, Asia, USA), CDMA (USA, Asia), and the like.

Technology development to effectively combine these two technologies while optimizing the functionality of the wireless ASP is currently underway in terms of browser and mark-up languages, access media and operating systems, networks, and location services.

XML stands for Extensible Markup Language and is an extensible markup language. XML is a standard (XML 1.0 specification) created by the World Wide Web (W3C) Consortium, and standardization on technologies related to XML is underway. It is, as its name suggests, an extensible language rather than a fixed format such as HTML. While HTML has a limited set of tags, XML allows you to define your own tags that are related to the content of your document, and make them available to others. XML is essentially a language for describing other languages, or meta languages. With the flexibility and extensibility of this XML, not only the information provided on the Internet in the future, but also all forms of information exchanged between companies, countries, and individuals will be written as XML documents.

The mobile ASP business stores various types of contents and applications on servers of service providers in the B2B and B2C markets and provides only the information and results of applications that customers want to have their own applications. Mobile ASP is a business that provides the service to achieve the desired result even if the information is not collected or scattered all over the place. Currently, only two or three companies in the US provide the solution partially. It provides solutions in the form of providing web contents and database contents through PDA or WAP. Although the market is not yet widely formed, if the use of wireless terminals is generalized and the quality of information service using wireless is improved, the market is expected to be broadly formed in B2B and B2C.

In Korea, there is a lack of mobile ASP technology. In Korea, many companies have introduced foreign solutions as they are for marketing, and some have announced that they have their own solutions. In many cases, the performance is minimal or does not actually hold. However, if it is suitable for the domestic market and its performance is superior to that of foreign products, it is expected that it will be able to secure the market as a product with sufficient competitiveness not only in the domestic market but also in the international market.

In other words, the conventional mobile ASP solution is limited to HTML documents, emails, and DB data, and simply provides content information, and provides a simple browsing-level interface or a separate client program for each content. there was.

The present invention is to meet the above expectations, the present invention is to provide a client independent of the content by using the information provided by the legacy system that the company has in addition to the information existing on the Web or database It is not necessary to separate version management that occurs when contents are increased or changed in the server / server system, and it provides a component-based user interface provided by the device rather than simple browsing, enabling wireless user screen composition and relocation by the administrator. Its purpose is to provide a service provider system.
