The present invention relates to a method for transmitting a wireless Internet access page menu to a mobile communication terminal, and more particularly, a header for forming a wireless Internet access page menu (menu for wap-connection) received from a content providing server in a swap gateway. The present invention relates to a method of transmitting a header and a body in a packet unit to a mobile communication terminal.

Recently, with the development of wireless Internet-related technology, users can access the wireless Internet through a mobile communication terminal and enjoy contents or search for information. In general, a user inputs a URL by operating a button of a mobile communication terminal to access a content provider (CP) to download various contents.

As described above, in order to access the wireless Internet, the user must directly input a URL every time, but since the user is connected to the corresponding content providing server, the user is troubled with button manipulation and URL memorization. In order to overcome this problem, that is, a wireless Internet access page menu (menu for wap-connection) is provided as a mobile communication terminal so that a mobile terminal user can easily access the wireless Internet.

Briefly describing the provision of a wireless Internet access page menu to a mobile communication terminal in the prior art is as follows. On the other hand, the known swap gateway is responsible for mediating data transmission and reception between the mobile communication terminal in the wireless network and the content providing server in the wired network.

First, when the user presses the wireless internet access button of the mobile communication terminal, the mobile communication terminal sends a Get Message to the content providing server through a WAP gateway and requests the wireless internet access page menu to be transmitted. . Here, the get message is a request signal for transmitting one object (image, etc.) included in the wireless Internet access page menu, and a post message is used as a plurality of object transmission request signals. In other words, unlike a wired network, in a wireless network, due to resource limitations such as wireless channel bandwidth and latency, post message, which is a large file transfer / response method, is not well used to transmit / receive a wireless Internet access page menu. Post message usage restrictions].

Then, the content providing server sends a wireless internet access page menu corresponding to the request message of the get message to the mobile communication terminal through the swap gateway, and responds to the request for transmitting the wireless internet access page menu. Here, the wireless Internet access page menu includes an icon in the form of an image representing a swap page, a textual description of the swap page, a URL indicating the swap page, and the like.

As described above, the get message transmission and response are repeatedly performed several times between the mobile communication terminal, the swap gateway, and the content providing server, and the wireless internet access page menu is downloaded to the mobile communication terminal. By selecting it, you can easily access the corresponding content providing server.

As described above, when the content providing server receives the get message from the mobile communication terminal through the swap gateway, the wireless Internet access page menu corresponding to the get message is transmitted to the mobile communication terminal through the swap gateway. do. In particular, the content providing server delivers one header and a plurality of bodies, each of which has a wireless Internet access page menu, to a swap gateway separately in order, so that the swap gateway is provided from the content providing server. Each received header and each body are relayed to the mobile communication terminal in order. Here, the wireless internet access page menu is composed of one header and a plurality of bodies, and the header includes information indicating an IP address, body summary information, body size, and body type, for example, whether the menu is text or an image. For example, data about a file constituting one image is divided and inserted into a plurality of bodies.

However, in the prior art as described above, the content providing server transmits one header constituting the wireless Internet access page menu to the mobile communication terminal through the swap gateway, and then transmits body # 1 to the mobile communication terminal through the swap gateway. Then transmit body # 2 to the mobile terminal through the swap gateway, and then the body # 3,... Then, body #N is continuously transmitted to the mobile communication terminal separately through the swap gateway. Accordingly, in the mobile communication terminal, the header, body # 1,... In addition, the body #N is separately received according to the transmission period of the swap gateway, which takes a considerable time to download a single wireless internet access page menu, thus delaying the wireless internet access to the user.

That is, the existing content providing server configures a header with a small data size in consideration of wireless channel characteristics such as long latency of a wireless communication network, and configures one image with multiple bodies each having a small data size. It is implemented to transmit to the mobile communication terminal separately through the swap gateway.

In other words, the content providing server according to the related art is built on or extends an existing wireless communication network such as an IS 95A / B network, and moves data as it is even if one header does not form one packet. Sending to communication terminal.

Accordingly, the mobile communication terminal receives two data (header and body) separately from the content providing server in receiving one packet [header + body]. This causes a delay of about 0.7 to 1 second for a mobile terminal to download one packet. However, thanks to the recent developments in CDMA2000 1X-EVDO network, WCDMA network, HSDPA transmission technology, and wireless packet data network equipment, there is no problem in transmitting data in packet units as well as wired communication network.

On the other hand, in order to overcome the above-mentioned problems, a method of changing the wireless Internet access page menu transmission process of the content providing server may be considered, but at present, hundreds of content providing servers are in operation in the wireless communication network. It is difficult to change the provider server providers uniformly.

Therefore, it is easy to change the process by the operation of the mobile telecommunication company, and ten minutes to the intermediary function of the swap gateway, for example, the wireless Internet connection page menu response intermediation function between the mobile communication terminal and the content providing server. There is an urgent need for a technology that can shorten the wireless Internet access time of the mobile communication terminal.

The present invention has been proposed to solve the above problems and to meet the above demands, and includes a header for forming a menu for a wireless Internet access page (menu for wap-connection) received from a content providing server at a swap gateway. It is an object of the present invention to provide a method for transmitting a mobile communication terminal by configuring a body in a packet unit.

In order to achieve the above object, the present invention provides a method of transmitting a wireless Internet access page menu (hereinafter, referred to as a "menu") received from a content providing server in a swap gateway to a mobile communication terminal. Mediating the menu request signal to the content providing server when a menu request signal is received; Upon receipt of a header corresponding to the menu from the content providing server, suspending the header mediation and waiting for a body corresponding to the header to be received from the content providing server; And receiving the body corresponding to the header from the content providing server, combining the header and the body into one packet and transmitting the combined body to the mobile communication terminal.

In addition, the present invention combines the header and the body into one packet and transmits it to the mobile communication terminal, and when receiving the next body corresponding to this header from the content providing server, the mobile communication terminal receives each body as soon as it is received. It further comprises the step of transmitting sequentially.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

1 is a configuration diagram of an embodiment of a communication network to which the present invention is applied.

As shown in FIG. 1, a communication network to which the present invention is applied includes a mobile communication terminal 10, a base station controller 20, a packet data serving node 30, a swap gateway 40, and a content providing server 50. do. Meanwhile, in the present invention, a base station is provided in the base station controller 20 as an example, and in addition, the communication network further includes basic components for mobile communication and data communication, such as a mobile communication switching center and a home location register. It is provided.

In the present invention, even if the content providing server 50 does not transmit the header and the body constituting the wireless Internet access page menu in packet units, the swap gateway 40 uses the wireless Internet access page menu received from the content providing server 50. The header and the body are formed in packet units and transmitted to the mobile communication terminal 10.

To this end, the swap gateway 40 waits for a header and a body corresponding to a get message of the mobile communication terminal 10, for example, a request for transmitting a wireless Internet access page menu, from the content providing server 50. When the corresponding header is received, the header transmission is temporarily suspended. With reference to this header information, when the corresponding body is received, the header and the body are combined into one packet and transmitted to the mobile communication terminal 10. Each of the received bodies is sequentially transmitted to the mobile communication terminal 10.

The mobile communication terminal 10 establishes a TCP / IP session between the swap gateway 40 and the content providing server 50, for example, a packet data serving node 30 according to a wireless internet access request signal of the mobile communication terminal 10. In the state where the IP address is assigned by using a get message to the content providing server 50 requests a wireless Internet access page menu.

In addition to the get message, the mobile communication terminal 10 may request a wireless Internet access page menu from the content providing server 50 using a post message.

The swap gateway 40 supports the mobile communication terminal 10 through wireless internet mediation, that is, get message mediation and wireless internet access page menu mediation. Such a swap gateway 40 is preferably operated by a mobile carrier, and is implemented as a plurality of servers. A plurality of servers for supporting the 1.3 protocol, a plurality of servers for supporting the swap 2.0 protocol, and a wideband code division multiple access scheme It is implemented as a number of servers for supporting the WCDMA WAP protocol.

The content providing server 50 provides a wireless Internet access page menu, various contents, etc. to the mobile communication terminal 10. The content providing server 50 is operated by each content provider, and the present invention will be described using one content providing server 50 as an example.

2 is a flowchart illustrating a method for transmitting a wireless Internet access page menu according to the present invention. Hereinafter, one object included in the wireless Internet access page menu using a get message [eg; Image] is described as an example of downloading from the content providing server 50 as a header and a body, and this one object, for example, one image file is described as an example of being transmitted to the body # 1 and the body # 2. Let's do it.

First, in a state in which a TCP / IP session is established between the mobile communication terminal 10, the swap gateway 40, and the content providing server 50 (200), the mobile communication terminal 10 uses a get message to use a swap gateway. Request 40 the wireless Internet access page menu (201).

Then, the swap gateway 40 transmits a get message, which is a request for a wireless Internet access page menu of the mobile communication terminal 10, to a corresponding content providing server 40, for example, a destination IP address of the get message, using a known signal intermediation function. It transmits to the corresponding content providing server 40 (202).

In addition, the swap gateway 40 requests a wireless Internet access page menu request from the content providing server 40, and a header corresponding to the wireless internet access page menu requested from the mobile communication terminal 10 includes a content providing server ( Wait for reception from 50).

Subsequently, the content providing server 50 transmits only the header corresponding to the wireless Internet access page menu requested from the mobile communication terminal 10 to the swap gateway 40 in a known manner (204).

Then, the swap gateway 40 waits to receive the header, and when the header corresponding to the wireless Internet access page menu is received from the content providing server 50, the swap gateway 40 temporarily suspends the header to the mobile communication terminal 10. In addition, it waits for the body # 1 corresponding to this header to be received from the content providing server 50 (205). At this time, the known swap gateway 40 grasps the data received from the content providing server 50, that is, the destination IP address, body summary information, body size, and body type of the header, and relays the header to any mobile communication terminal. In the present invention, the swap gateway 40 determines in advance how many more bodies will be received through body summary information, body size, etc. without transmitting a header to the mobile communication terminal 10. Waits for further body # 1 to be received in order to join the header and body.

Subsequently, the content providing server 50 transmits the body # 1 following the header to the swap gateway 40 in a known manner (206).

Then, when the swap gateway 40 waits to receive the body # 1 and receives the body # 1 corresponding to the header from the content providing server 50, the swap gateway 40 receives one packet between the header and the body # 1 that have been suspended. Combined and transmitted to the mobile communication terminal (207, 208).

Thereafter, the content providing server 50 transmits the body # 2 following the body # 1 to the swap gateway 40 in a known manner, and the swap gateway 40 receives the content providing server 50 from the content providing server 50. The body # 2 is relayed to the mobile communication terminal 10 in the order of reception thereof (209 and 210).

On the other hand, in the above-described embodiment of the present invention has been described with an example of having two bodies for one object, when the object is composed of a plurality of bodies, the content providing server 50 in the body in a known manner For example, body # 2, body # 3,... , Body #N is transmitted to the swap gateway 40 in order. When the swap gateway 40 of the present invention receives the following bodies from the content providing server 50, the bodies #N and the body # 3 are received. ,… As soon as the body #N is received, the body #N is sequentially transmitted to the mobile communication terminal 10.

Meanwhile, in the above-described embodiment of the present invention, the wireless internet access page menu corresponding to one get message, in particular, the transmission / reception process for one object has been described as an example. The mobile communication terminal 10 transmits a get message corresponding to each object to the content providing server 50 through the swap gateway 40. Accordingly, the swap gateway 40 of the present invention is an object corresponding to each get message. The header and body # 1 are combined into one packet and transmitted to the mobile communication terminal, and successive bodies corresponding to the header are transmitted to the mobile communication terminal.

Meanwhile, the mobile communication terminal downloads the wireless internet access page menu using a post message instead of a get message. That is, the post message is a request signal used when requesting several objects at once. Even though the content providing server receives the post message, the post message sends headers and bodies forming each object sequentially, and then the headers and bodies forming another object sequentially. send. Therefore, since the swap gateway 40 receives the headers and the bodies corresponding to the post message sequentially for each object, the swap gateway 40 may perform the same process as the above-described embodiment of the present invention.

While the content of the present invention has been described by way of examples, the embodiments of the present invention are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art to which the present invention pertains may modify or alter the present invention in various forms within the principles and scope described in the claims herein.

The present invention as described above can shorten the download time of the wireless Internet access page menu of the mobile communication terminal, thereby preventing the delay of the user's wireless Internet access.

In addition, since the present invention only needs to change the Wi-Fi access page menu response intermediation process of the swap gateway, operators can easily change the process more efficiently than changing the processes of hundreds of different content providing servers. It works.
