Description

Wireless internet broadcasting providing system using CBS {Wireless internet broadcasting providing system using CBS}

The present invention relates to wireless internet broadcasting of a cell broadcasting system (CBS), and provides information through wireless internet broadcasting even when subscribers simultaneously access a response to a received CBS message when performing wireless internet broadcasting using a CBS. The present invention relates to a wireless Internet broadcasting providing system in a CBS system for stably transmitting.

CBS, unlike the existing short message service (SMS), is a technology for sending text information to multiple subscribers simultaneously. CBS can send text information to millions or more of subscribers in a single transmission, and can also send messages to local units (province, district, town).

This, using the CBS reply (URL, ARS number) performs a wireless Internet broadcast. That is, the CBS transmits a URL and an ARS number for replying together with the text information. Therefore, when the terminal receiving the text information wants to access the wireless internet broadcasting, the terminals are connected through the wireless internet gateway of the corresponding communication company.

1 is a block diagram illustrating a wireless Internet broadcasting providing system using a general CBS.

1 is a CBS 10 for transmitting text information, a terminal 11 for receiving text information from the CBS 10, a wireless Internet gateway 12 for accessing wireless Internet broadcasting, and access to the Internet. And a data input system 13 for inputting data for wireless Internet broadcasting. In addition, FIG. 1 controls a DNS (domain name system) server 14 connected to a wireless Internet gateway 12 and the Internet, a cluster server 15 for clustering, and each configuration for providing wireless Internet broadcasting on a swap. A swap server 16, a main DB 17 storing data for broadcasting, and a data input server receiving data from the data input system 13 in conjunction with the Internet and outputting the data to the main DB 17 ( 18).

In FIG. 1, the CBS 10 simultaneously transmits a URL or ARS number for replying with text information to numerous subscribers. Then, it is assumed that the received text information is displayed on the screen of the terminal 11, and at the same time, a URL for accessing the corresponding swap site is received. If the user wants to see the related contents with respect to the text information received on the screen of the terminal 11 in more detail, the user attempts to access the corresponding URL. Then, the terminal 11 is connected to the DNS server 14 of the URL through the wireless Internet gateway 12. When the connection of the DNS server 14 is completed, the cluster server 15 performs clustering to connect to the swap server 16. The swap server 16 reads and transmits information stored in the main DB 17 to transmit the requested broadcast information to the connected terminal 11. The main DB 17 receives broadcast information to be provided from the data input server 18. The data input server 18 outputs to the main DB 17 using broadcast information input from the data input system 13 connected to the Internet. One or more data input systems 13 may be connected via the Internet. For example, each computer may input broadcast information such as a broadcast PD. That is, the data input system 13 connects with the data input server 18 through the Internet and inputs broadcast information. The data input server 18 outputs the input broadcast information to the main DB 17. The broadcast information stored in the main DB 17 is read out at the request of the swap server 16 by a request from the terminal 11. The swap server 16 transmits the read broadcasting information to the terminal 11 through the wireless internet gateway 12. Then, the user can receive the wireless Internet broadcast received in his terminal (11).

Until now, WAP has not generated excessive traffic such as WEB due to the limitation of domestic specific mobile communication and the closure of wireless Internet service.

The simultaneous connection of users according to the wireless Internet broadcasting will continue to increase. As the number of applications using CBS increases, the number of concurrent users will increase, and the cost burden for CBS service providers will increase.

However, the conventional wireless Internet broadcasting providing system has no countermeasures against simultaneous access and excessive traffic of users, and even if a DB and a swap server are added in order to prepare for a large number of concurrent users, the service speed is reduced and smooth. There was a problem that a broadcast accident that can not support the service may occur.

Accordingly, an object of the present invention is not to rely on the expansion of the DB and the swap server even when a large number of concurrent users occur so that the above-mentioned problems can be solved. The present invention provides a wireless Internet broadcasting providing system using a CBS to transmit stored pre-published broadcast information.

Hereinafter, with reference to the accompanying Figure 2 will be described in detail a preferred embodiment of the present invention.

2 is a block diagram illustrating a wireless Internet broadcasting providing system using CBS according to an embodiment of the present invention.

2 is a CBS 20 for transmitting text information, a terminal 21 for receiving text information from the CBS 20, and requesting wireless Internet broadcast information, and a wireless Internet at the request of the terminal 21. A broadcast providing device 24 for transmitting broadcast information, a wireless Internet gateway 22 for connecting the broadcast providing device 24 and the terminal 21, and a data input system for inputting broadcast information through the Internet. And (23). In addition, the broadcast providing device 24 includes a DNS (domain name system) server 241 connected to the wireless Internet gateway 22 and the Internet, a cluster server 242 for clustering, and a wireless Internet broadcast on a swap. A swap server 243 for controlling each configuration, a swap publishing server 246 for documenting and providing swap published broadcast information to the swap server 243, and a main DB 247 for storing data for providing broadcast information. And a data input server 248 that receives data from the data input system 23 in association with the Internet and outputs the data to the main DB 247. The swap server 243 may configure a plurality of swap servers (not shown), including the first swap server 244 and the second swap server 245.

The operation of the wireless Internet broadcasting providing system of FIG. 2 configured as described above will be described in more detail.

In FIG. 2, the CBS 20 simultaneously transmits a URL or ARS number for replying with text information to numerous subscribers. Then, it is assumed that the received text information is displayed on the screen of the terminal 21, and at the same time, a URL for accessing the corresponding swap site is received. If the user wants to see the related contents in detail about the text information received on the screen of the terminal 21, the user attempts to access the corresponding URL. Then, the terminal 21 is connected to the DNS server 241 of the URL through the wireless Internet gateway 22. When the connection of the DNS server 241 is completed, the cluster server 242 performs clustering (clustering) to connect to the swap server 243. That is, when a plurality of terminals are connected, clustering with the first and second swap servers 244 and 245 in the swap server 243 is performed.

On the other hand, the data input system 23 is connected to the data input server 248 via the Internet. Then, the data input system 23 transmits the data for providing broadcast information to the connected data input server 248. The data input server 248 outputs the input data to the main DB 247. The main DB 247 outputs the input data to the swap publishing server 246. At this time, the swap document output from the main DB 247 is D (dynamic) WML (wireless markup language). For a case where many users connect at the same time, the swap publishing server 246 converts the DWML to S (static) WML. The converted SWML document is distributed in order to the first and second swap servers 244 and 245 of the swap server 243 and stored.

Accordingly, the swap server 243 reads and transmits the swap published broadcast information stored in the first swap server 244 to transmit the requested broadcast information to the connected terminal 21. That is, the swap server 243 transmits the read swapped broadcast information to the terminal 21 through the wireless Internet gateway 22. Then, the user can receive the wireless Internet broadcast received in his terminal 21. When another terminal (not shown) other than the terminal 21 is connected, the broadcasting information stored in the second swap server 244 is read and transmitted, and in the case of a plurality of other instances, the expansion of the swap server 243 can be sufficiently realized. In the present invention, the terminal and the swap server are described as one-to-one correspondence, but in reality, a plurality of terminals simultaneously connected are equally allocated to the plurality of swap servers. For example, if there are two swap servers for 100,000 terminals simultaneously connected, 50,000 terminals are allocated to one swap server to receive information.

Accordingly, the apparatus of the present invention can provide broadcast information even when a plurality of terminals are simultaneously connected to the swap server by performing the swap publishing, and even if the connection is congested, the service can be provided only by the expansion of the swap server.
