The present invention relates to an apparatus and method for providing a FastWeb service, and more particularly, to an apparatus and method for providing a FastWeb service between a wired network and a wireless network more efficiently in providing a web service to service users in a mobile communication environment. It is about.

Thanks to the development of mobile communication terminals, ordinary users can easily access the Internet even on the bus or subway. However, wireless environments generally have slower communication channel characteristics than wired environments. This is due to the fact that the mobile communication channel is narrow compared to the wired one and poor in noise. In addition, the usage fee is also higher than that of a wired line because of the limited communication resources.

Currently, mobile terminal users exchange data with servers in a wired network using their mobile terminals. Of course, the data used by the mobile communication service users are highly compressed compared to the data that is not, but due to the nature of the mobile environment, a narrow bandwidth and relatively expensive packet fee should be paid. Therefore, there is a need for a method that can reduce the amount of data in the wireless section as much as possible to reduce the cost of users and improve the data transmission speed.

1 is a diagram illustrating a method of providing an Internet service in an existing mobile environment. In this method, the end mobile communication service users 110 must go through the wired network 140 and the wireless network 120 environment in order to receive content from the content servers 150 in the wired network 140, and provide general web services. The mobile communication service provider 130 only serves to connect the wired network and the mobile network. In this case, since the data content is delivered to the end mobile communication service user 110 without any compression or transcoding, there is a problem that the efficiency is significantly reduced in a mobile communication environment having a relatively narrow bandwidth.

The technical problem to be achieved by the present invention is to provide a web service to service users in a mobile communication environment, to effectively reduce the amount of data exchanged in the narrowband mobile communication environment by reducing the amount of the wired network and more efficiently It is to provide a device that performs FastWeb service between wireless networks.

Another object of the present invention is to provide a method for efficiently performing a FastWeb service between a wired network and a wireless network.

In order to achieve the above technical problem, an embodiment of a FastWeb service providing apparatus in a wired or wireless network according to the present invention, a wired communication unit for receiving text-based general web service data from the wired network; A protocol converter configured to compress and encode general web service data using a FastWeb method in a binary format; And a wireless communication unit for transmitting compression-encoded data to a wireless network in a FastWeb manner.

In addition, according to an embodiment of the present invention, a method for providing a FastWeb service in a wired or wireless network according to the present invention, a client of a wireless network using a FastWeb service is connected to the FastWeb service providing apparatus to provide information of specific data. Requesting; Retrieving specific data from a cache within the FastWeb service providing device; And if the specific data is not found in the search step, the FastWeb service providing apparatus receives the specific data from the wired network and compresses and encodes the specific data using the FastWeb method.

In order to provide services to users in a mobile communication environment at a lower cost, it is important to reduce the capacity of the same data by efficiently compressing or transcoding the data passing through the mobile communication section. By transmitting this reduced data, Internet users can save not only fast data transfer but also royalties, and offer service providers the opportunity to secure multiple customers.

The present invention provides a high speed Internet at a lower cost than the current Internet in the current wired / wireless Internet environment by effectively reducing the capacity of data transmitted by wires when using the Internet using FastWeb service. It provides an apparatus and method that can be.

FastWeb is a technology currently being promoted as an international standard by an international standards organization called ISO / IEC JTC1 / SC6. It operates in the same way as the existing web service. However, while existing web services use text-based instructions (html, xml, etc.), fast web services transmit not only text-based instructions used by existing web services, but also the contents transmitted by using binary compression. It is a technology that can drastically reduce the amount of data that is compared to the existing web service.

Hereinafter, an apparatus and method for providing a FastWeb service in a wired / wireless network according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram illustrating a method for providing an Internet service in a FastWeb environment according to an embodiment of the present invention.

Referring to FIG. 2, entities participating in the service proposed by the present invention are largely mobile using the end mobile communication service user 210, the wireless network 220, and the FastWeb portal / gateway. The communication service provider 230, the wired network 240, and the content server 250 located in the wired network can be divided into five types. Through these entities, the end mobile communication service users 210 may effectively receive content through wired and wireless environments. The content server 250 may be a web server, a media server, or the like, but is not limited thereto.

If the end mobile communication service users 210 need to receive content from the content server 150 in the wired network 140, the end mobile communication service users 210 must pass through the wired network 140 and the wireless network 120 environment. At this time, between the mobile communication service provider 230 and the content server 250 is a normal web service section in which general content is used. In the general web service section, text-based data exists as with general web services.

The mobile communication service provider 230 may reduce the amount of data required to deliver content by using a FastWeb portal / gateway. FastWeb service is a technology that can convert textual data into binary code or restore binary code to original data. The FastWeb service can be expected to have an excellent effect on data compression and security compared to transmitting data such as text. Therefore, in the FastWeb service interval between the end mobile communication service user 210 and the mobile communication service provider 230, there is data of binary code compression-encoded by FastWeb service method, not original data.

Referring to FIG. 3, the FastWeb portal / gateway, that is, the FastWeb service providing apparatus 300 in a wired / wireless network includes a wired communication unit 310, a protocol conversion unit 320, and a wireless communication unit 330.

The wired communication unit 310 serves to receive text-based general web service data from the wired network, and the protocol conversion unit 320 receives the general web service data received from the wired communication unit 310 in a binary format. Perform encoding by compressing with FastWeb method. In addition, the wireless communication unit 330 plays a role of transmitting data encoded and encoded by the FastWeb method to the wireless network, and includes a FastWeb processing unit 335 for this purpose.

 FastWeb service providing apparatus 300 serves to connect a wired network and a wireless network as described in FIG. To connect wired and wireless networks, FastWeb portals / gateways have more than one interface. The first is a wired interface 311 for connecting with a wired network, and the other is a wireless interface 331 for connecting with a wireless network.

Hereinafter, for a detailed description of the FastWeb service providing apparatus 300, a process in which a client of a wireless network receives web data from a server of a wired network will be described as an example.

Data transmitted from the web server of the wired network to the wireless network first passes through the wired network to reach the wired communication unit 310 of the FastWeb service providing apparatus 300.

Data from the wired network is transmitted to the device through the wired interface 311 of the wired communication unit 310, and the data is transmitted to a network layer such as IP (Internet Protocol), more precisely, the protocol 312, TCP of the wired network layer. The protocol converter 320 is reached via a transport layer such as Transmission Control Protocol, more specifically, a transport layer protocol 313 of a wired environment and a general HTTP processor 314 that handles an application layer protocol such as HTTP.

The protocol converter 320 is a module that compresses / restores general web service data using HTML, XML, or the like into a FastWeb service data type, and may be referred to as a protocol gateway module or a redirector.

The protocol converter 320 not only converts a data format into a FastWeb data format, but also converts FastWeb service data into general web service data in the reverse direction.

Data that has been compressed and encoded in the FastWeb manner by reaching the protocol converter 320 may be stored in its cache 340 in order to respond quickly to requests from clients of the wireless network. The operation of protocol converter 320 and cache 340 is described in detail in FIG.

The wireless communication unit 330 transmits the data encoded by the FastWeb method to the wireless network. More specifically, the data encoded by the protocol converter 320 is processed by the FastWeb processor 335 to be sent to the end mobile communication service in the wireless network. The processed data arrives at the air interface 331 through the transport layer protocol 333 and the wireless network protocol 332 or the communication middleware 334 in the wireless environment. Data arriving at the air interface 331 flows into the wireless network.

Until now, a process for transferring data in a wired environment to a wireless environment has been described, and in the case of transferring data from a wireless environment to a wired environment, it may operate in the reverse direction of the above-described method.

That is, the wireless communication unit 330 receives the FastWeb method data from the wireless network, the protocol converter 320 restores the FastWeb method data received by the wireless communication unit to the original general web service data, and wired communication unit 310 ) May be characterized in that to transmit the restored data to the wired network.

4 is an internal configuration diagram of an end mobile communication service user terminal receiving data from a FastWeb portal / gateway.

FastWeb data reached through the wireless network is delivered to the device via the wireless interface 431 of the end mobile service user. This data then arrives at FastWeb processor 435 via wireless network layer protocol 432 and wireless transport layer protocol 433 or communication middleware 434. The FastWeb processing unit 435 processes the data in the opposite manner to that processed by the FastWeb processing unit 335 of the FastWeb portal / gateway 300 (see FIG. 3) (245). The processed data is delivered to the application layer 410 of the end mobile communication service user, and then the application application processes the data.

5 is a diagram illustrating a method of providing a FastWeb service between a plurality of wired and wireless communication entities using the present invention.

Until now, only the case of transmitting and receiving data between the server of the wired network and the client of the wireless network has been described, the present invention can be applied to the communication environment between the wireless network passing through the wired network as shown in FIG. FastWeb data of both clients 510 and 550 participating in the communication may be transmitted to the wired network 540 through FastWeb portals / gateways 530a and 530b located in their wireless networks 520a and 520b. Operation of each entity participating in such a communication environment is as described with reference to FIGS. 3 and 4.

The contents covered by the present invention can be used for all communication schemes in wired and wireless environments. However, a case of providing a web caching service in the same manner as in FIG. 6 through the method proposed by the present invention will be described in order to give a more specific embodiment.

In more detail, the service is started by the client as the end mobile communication service user accesses the mobile communication service provider (S611). The client sends a message requesting information of a specific site to the service provider (S612). According to this request, the service provider checks whether site information requested by the user is stored in its cache (S613). If desired information exists in the cache (S614), a data copy is extracted from the cache (S631). Thereafter, the compressed data is transmitted to the client by FastWeb (S641). After all requests are completed, the client terminates the connection (S642).

If the desired information does not exist in the cache, data is requested from the original data server in the wired network (S621), and data is received from the original data server (S622). The received data is stored in the cache and the cache is updated (S623), and then encoded in the FastWeb method (S624) and transmitted to the client (S641). If the requested data is not received from the original data server of the wired network, an error is generated (S625), and then encoded in a FastWeb method (S624) and transmitted to the client (S641).

The present invention can be utilized in the form of a web portal service or a proxy to a service user of a mobile environment.

The invention can also be embodied as computer readable code on a computer readable recording medium. Computer-readable recording media include all types of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, which may also be implemented in the form of carrier waves (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
