Description

Broadcasting method using mobile communication base station as transmission station {METHOD FOR BROADCASTING DATA USING BASE STATION THAT SUBSTITUTED FOR REPLAY STATION}

The present invention relates to a broadcasting method using a mobile communication base station as a relay station, and a computer-readable recording medium recording a program for realizing the method. In particular, the present invention relates to a multicasting method using a base station of a mobile communication network. The present invention relates to a method for allocating a radio resource (traffic channel) and broadcasting multimedia data to a mobile data host of a subscriber of a mobile communication network, and a computer-readable recording medium storing a program for realizing the method.

In the present invention, a mobile communication base station, a mobile communication network, and the like are described. Here, the mobile communication refers to a wireless communication such as cellular communication, personal communication system (PCS), next generation mobile communication (IMT-2000), and the like.

In general, the existing air broadcasting has a problem that the channel is limited because the frequency bandwidth is narrow in transmitting the video signal through the transmission center, and the mobile communication method uses the WAP (Wireless Application Protocol). Multimedia data is transmitted in the form of Demand, and the traffic channel is inefficiently used and the load of the system is increased by dedicating the individually allocated circuits through the PPP (PPP: Point to Point Protocol) between the base station and the mobile host terminal. And there was a problem of increasing the subscriber's line fee burden.

That is, over-the-air broadcasting can be broadcasted by multicasting, so anyone with a TV receiver can watch the broadcast, while the available radio frequency bandwidth is limited, so VHF (Very High Frequency) and UHF (Ultra High Frequency) are available. Since the number of channels cannot be increased, it is difficult to expand channels to satisfy various needs of viewers.

In addition, the broadcasting method using the mobile communication network was using the on-demand unicasting (Unicasting) method using PPP. That is, unicasting type broadcasting is used to transmit content requested by mobile subscribers individually between the host and the terminal by using push technology. In such a situation, the amount of money invested in order to service a variety of contents to meet the needs of viewers is large, whereas the amount payable by the viewers is small, making it difficult to provide the majority of contents.

Accordingly, the present invention has been made to solve the above-described problems, and the mobile terminal is to process the content transmission by the broadcast method between the base station and the user's mobile terminal to transmit more various types of information through limited radio resources. It is an object of the present invention to provide a broadcasting method using a communication base station as a relay station and a computer-readable recording medium recording a program for realizing the method.

That is, according to the present invention, a broadcast station can be freely used within the area of simultaneous communication subscribers by utilizing a mobile communication base station as a relay station, and a viewer who wants to watch the same broadcasting channel with one traffic channel by using a multicasting method. The present invention aims to provide a subscriber to a mobile communication network a broadcasting method using a mobile communication base station that can provide unlimited multimedia data as a relay station and a computer-readable recording medium recording a program for realizing the method. have.

Referring to the broadcast method using a mobile communication base station as a relay station according to the present invention according to the flow of the drawings as follows.

First, a mobile data host is requested to broadcast through a broadcast button from a user and receives a corresponding broadcast channel number (401).

The mobile communication terminal receiving the broadcast request transmits the broadcast request of the corresponding channel received from the user to the mobile communication base station through the communication channel (402), and the mobile communication base station broadcasts the corresponding channel transmitted from the mobile communication terminal. The request is received (403).

The mobile communication base station identifies the user by searching the user information through the connected server (404).

The relay office checks the reception status to see if the user's mobile data host can receive the broadcast after determining that the user information is confirmed to be a normal mobile data host (405). It is determined whether casting reception is possible (406).

As a result of determining whether the mobile data host can receive the broadcast, if the broadcast reception is possible, it is checked whether the broadcast channel desired by the user is already multicasted through the traffic channel (407).

After confirming that the desired broadcasting channel is already multicasted through the traffic channel, if it is not multicasted, the mobile base station allocates a traffic channel to transmit the desired broadcasting channel in a multicast manner (408). Inform 409 of the allocated traffic channel to the user's mobile data host.

As a result of checking whether the channel desired by the user is already multicasted through the traffic channel, if the multicasting is performed, the mobile communication base station notifies the user of the mobile data host of the traffic channel whose channel is multicasted (409). .

In this case, notifying the user of the traffic channel means providing information for identifying the traffic channel so that the user can receive it.

The mobile communication base station transmits data of the broadcasting channel requested by the user through a multicasting method through the corresponding traffic channel notified to the user's mobile data host (410), and the user's mobile data host transmits the request channel transmitted by the multicasting method. Receive the data of the data provided to the user (411).

Through this process, the user can check the broadcasting. This means that not only broadcasting but also other information can be delivered to multiple people.

If the mobile data host determines that the broadcast reception is possible, if the broadcast reception is not possible, the mobile communication base station notifies the mobile data host that broadcast reception is impossible (412), and the mobile data host notifies the user. (413).

In the above embodiment, while receiving a broadcast request from the user and receiving a channel number, the mobile data host may receive a broadcast channel input after confirming that the broadcast data can be received. have.

In the above-described embodiment, the expression broadcasting and the expression multicasting are used together. In this case, broadcasting is a concept of broadcasting, and the same data is transmitted to several mobile data hosts (mobile communication terminals) at the same time as in the concept of over-the-air broadcasting. It is a conceptual representation of the possibility that, in practice, the transfer of this data is done in a multicasting manner between the mobile communication base station (transmission station) and the serviced mobile data hosts (mobile communication terminals).
