DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, a mobile phone broadcasting service system according to the present invention includes an information providing system 10, a mobile phone broadcasting system 30, a plurality of mobile phone terminals 60, and a wireless network 50 having an Internet network 20 connecting these systems to one another and a separate base station.
Referring to FIG. 2, the information providing system 10 includes a dedicated content server 11, a web server 12 and a router 13.
The dedicated content server 11 processes a variety of updated information into the forms of voice, multimedia, text and image data. In other words, the dedicated content server 11 processes various types of information in order to provide useful information in real time to the mobile phone terminals 60 used by mobile phone broadcasting information providing service subscribers.
The web server 12 constructs a web-based service environment in which the processed information is to be provided to the mobile phone broadcasting system 30 over the Internet network 20. The router 13 specifies the most efficient path for transmission of the processed information.
Referring to FIG. 3, the mobile phone broadcasting system 30 includes a router 31, a mobile phone broadcasting server 32, an automatic response system (ARS) 33, a wireless Internet broadcasting server 34, a cell broadcasting system (CBS) 35, an Inter-gateway system (IGS) 36, an Inter-working function server (IWF) 37, a dedicated packet network 38 and a mobile switching center (MSC) 39. Here, the mobile phone broadcasting server 32, the ARS 33 and the wireless Internet broadcasting server 34 are collectively referred to as a mobile phone broadcasting platform 40.
The router 31 specifies the most efficient path for receiving the information processed and transmitted from the information providing system 10.
The mobile phone broadcasting server 32 categorizes and separates the information received from the information providing system 10 via the router 31 as voice information, multimedia information, text information or image information.
The ARS 33 stores the voice information separated by the mobile phone broadcasting server 32 and automatically provides the voice information upon request by the mobile phone terminals 60.
The wireless Internet broadcasting server 34 stores the multimedia information separated by the mobile phone broadcasting server 32 and automatically provides the multimedia information upon request by the mobile phone terminals 60.
The CBS 35 receives and manages the text information and the image information separated by the mobile phone broadcasting server 32, transmits the information to the wireless network 50 upon request, and transmits the information to the mobile phone terminals 60 via the scoreless network 50 that has passed through the base station simultaneously in real time.
When voice information is separately requested by the mobile phone terminals 60, connection to the MSC 39 is made via the wireless network 50 and the ARS 33 is connected through the IGS 36, that is, a gateway for voice communication.
When voice information is separately requested by the mobile phone terminals 60, a connection to the MSC 39 is made via the wireless network 50 and the ARS 33 is connected through the IGS 36, that is, a gateway for voice communication.
When wireless Internet information is separately requested by the mobile phone terminals 60, a connection to the MSC 39 is made via the wireless network 50 and the wireless Internet broadcasting server 34 is connected through the IWF 37, that is, a gateway for data communication. Hero, in the case where the mobile phone terminals 60 support packet transmission of CDMA2000-IX network or the like, a direct connection to the wireless Internet broadcasting server 34 is made through the wireless network 50 and the dedicated packet network 38, without a separate gateway.
FIG. 4 is a flow diagram of a method of providing a mobile phone broadcasting service according to the present invention.
The mobile phone broadcasting service according to the present invention will now be described in detail with reference to FIG. 4. First, the information in the forms of voice, multimedia, text and image that has been processed by the information providing system 10 is transmitted to the mobile phone broadcasting system 30 through the Internet network 20 (First step: S 100).
Next the mobile phone broadcasting system 30 simultaneously transmits the text and image information among the received information, a linked phone number connected to the ARS 33 or a linked URL connected to the wireless Internet broadcasting server 34 to the plurality of mobile phone terminals 60 through the wireless network 50 (Second step: S200).
The mobile phone terminals 60 select, using the received information, the phone number linked to the ARS 33 if the voice information is desired, and the URL linked to the wireless Internet broadcasting server 34 if the multimedia information is desired. Then, the ARS 33 or the wireless Internet broadcasting server 34 is connected according to the selection of the linked phone number or URL to be provided with the voice or multimedia information (Third step: S300).
FIG. 5 is a flow diagram of a detailed embodiment of the second step shown in FIG. 4.
Referring to FIG. 5, the mobile phone broadcasting server 32 separates the information received from the information providing system 10 via the Internet network 20 into voice information, multimedia information, text information and image information (step S210).
Here, the separated voice information is transmitted to the ARS 33 and stored in a separate storage means (steps S220 and S230). The separated multimedia information is transmitted to the wireless Internet broadcasting server 34 and stored in a separate storage means (steps S240 and S250). Also, the separated text information and the separated image information are transmitted to the CBS 35 and stored in a separate storage means (steps S260 and S270).
Then, the text information and the image information stored in the storage means of the CBS 35, the phone number linked to the ARS 33 or the URL linked to the wireless Internet broadcasting server 34, are simultaneously transmitted in real time to the plurality of mobile phone terminals 60 through the wireless network 50 via the base station.
In an embodiment of the method of providing a mobile phone broadcasting service using the CBS, the text or image information may be transmitted to a predetermined subscriber of the mobile phone terminal according to the operator's selection, and charges for communication or use of information may be separately billed whenever the voice or multimedia information is used.
According to the present invention, useful information can be simultaneously transmitted to a plurality of mobile phone terminals in real time and an information service may be provided by means of a base station. Also, mass marketing tools can be advantageously utilized.
