Furthermore, the wireless broadcast control system 100 may perform the time synchronization function of one or more wireless broadcast receiving apparatuses 300. Specifically, when a current time is received through a device (for example, a CDMA modem or the like) that provides standard time information and the current time corresponds to a preset specific time (for example, 6:00 am) A time synchronization message for synchronizing the receiving apparatus with a specific time can be set and the corresponding time synchronization message can be transmitted to the wireless broadcast receiving apparatus 300 so that the wireless broadcast receiving apparatus 300 can perform time synchronization. For example, if the wireless broadcast control system 100 transmits a tone, which is a specific code, at a predetermined time, the wireless broadcast receiving apparatus 300 is synchronized at a predetermined time.

2 is a diagram illustrating a process of transmitting a wireless broadcast by a wireless broadcast control system according to an exemplary embodiment. The wireless broadcast control system 100 plays a role of supporting a broadcast service including announcements and the like by using wireless communication. Those who provide broadcasting are those who have certain authority in broadcasting such as village head. It is possible to effectively control unnecessary broadcasting such as advertisement, play, etc. by classifying the persons having the broadcasting authority in advance. A person having a broadcasting authority can transmit a character, which is a broadcast request message, to the wireless broadcast control system 100 using his / her wireless broadcast request apparatus 200. [ The wireless broadcast request apparatus 200 may be a mobile device that can be carried by a user and can send a character in a CDMA manner, for example, a smart phone, a PDA, a tablet, or the like. In addition, an application for sending texts to the wireless broadcast control system 100 may be used.

The wireless broadcast receiving apparatus 300 may have a variety of types, and the number of the wireless broadcast receiving apparatuses 300 may be one or more. That is, the wireless broadcast control system 100 may have information on the type of each wireless broadcast receiving apparatus 300, user information using the device, group information on the user grouping according to needs, and the like. For example, if village broadcasting for an elementary school located in a village is decided, a family group having elementary school students can be classified and stored in order to selectively broadcast a village broadcast only to an elementary school student who is attending the corresponding elementary school Can be managed.

3 is a block diagram of a wireless broadcast control system according to an embodiment. The wireless broadcast control system 100 includes a receiving unit 110 for receiving a broadcast request message or an emergency situation message, a user authentication unit 120 for authenticating who has a broadcasting right, A controller 130 for analyzing the received message to set broadcast contents, and an output unit 140 for transmitting broadcast contents to the wireless broadcast receiving apparatus 300. Hereinafter, each configuration will be described in detail.

The receiving unit 110 may receive a message from the user. The user may or may not be a broadcaster who has the authority to broadcast the town. A user can transmit a message using a wireless broadcast receiving apparatus such as a real smartphone or a wire telephone, so that the receiving unit 110 can perform wireless communication with the wireless broadcast requesting apparatus or the wireless broadcast receiving apparatus. have. In particular, when receiving a character from a wireless broadcast requesting device, it is necessary to include the user's phone number information. Therefore, the character can be received by the CDMA method instead of the 3G method. Also, if the broadcast request message is a real-time broadcast service, the user who has transmitted the broadcast request message can receive the broadcast content by making a reply call. At this time, the reply telephone can also follow the CDMA communication system.

In one embodiment, the user authentication unit 120 may perform user authentication based on a user phone number registered in advance, whether the user who transmitted the broadcast request message has broadcasting rights. For example, the user authentication unit 120 may include a telephone number list for a person who has broadcasting authority, and may compare the telephone number of the device that transmitted the broadcast request message with the telephone number list, It is possible to certify whether or not it is a broadcasting right.

On the other hand, the user authentication unit 120 may identify the wireless broadcast receiving apparatus that transmitted the emergency call message when receiving the emergency call message set in advance in another embodiment. Since the wireless broadcast control system has information on all the wireless broadcast receiving devices capable of wireless broadcast, when receiving the emergency call message, the wireless broadcast control system identifies the device through the telephone number of the wireless broadcast receiving device or the emergency code . Identifying the device that sent the emergency call message is to include information on who is the user who has experienced the emergency in the announcement broadcast. In addition, the location information of the wireless broadcast receiving apparatus may be provided automatically when an emergency situation is notified to an administrative institution such as a fire station, a police station, or the like.

In one embodiment, the control unit 130 may set broadcast contents according to a broadcast request message if the user who transmitted the message corresponds to a user having broadcast rights. Specifically, when the broadcast request message is a real-time broadcast request message, the broadcast content can be set by placing a reply call to the user and receiving a voice file generated by the user. On the other hand, if the broadcast request message is a non-real-time broadcast request message, the broadcast content can be set by selecting one selected from the list of recorded audio files corresponding to the non-real-time broadcast request message.

Also, the control unit 130 may determine a target wireless broadcast receiving apparatus to which the broadcast contents will be transmitted according to the broadcast request message. Since the wireless broadcast receiving apparatus has various types and includes all the receiving apparatuses capable of providing the wireless broadcast by the wireless broadcast control system 100, the control unit 130 may selectively set the broadcast target according to the nature of the wireless broadcast It is possible to do. The wireless broadcast receiving apparatus may be an outdoor apparatus or an indoor apparatus, and a broadcast object may be determined to include one or both of them.

In another embodiment, the controller 130 may determine the type of emergency based on the emergency call message, and determine the content of the broadcast including the type of emergency and user information using the identified wireless broadcast receiving apparatus. Furthermore, the broadcast destination to which the emergency call message is to be transmitted can be specified. At this time, the emergency call message is divided into a character code and can be synchronized information between the wireless broadcast receiving apparatus and the wireless broadcast control system 100. For example, if a user activates an emergency call device (for example, a pull cord or a button) through a wireless broadcast receiving device connected to an emergency call device provided in a specific home, the wireless broadcast receiving device automatically transmits the wireless broadcast control system 100 to the emergency call message A001 !. The wireless broadcast control system 100 confirms that A001 is Hong Kil-dong through an emergency call message, and confirms that an emergency situation has occurred from!.

The output unit 140 may transmit the broadcasting contents set by the controller 130 to the wireless broadcast receiving apparatus. The wireless broadcast receiving apparatus to be transmitted can also transmit the wireless broadcast only to the selected wireless broadcast receiving apparatus when the control unit 130 is specific. The output unit 140 can transmit broadcast contents using various wireless communication methods and can use, for example, UHF communication in a 400 MHz frequency band. The wireless communication method can be determined in the output unit 140 in accordance with the communication characteristics of the wireless broadcast receiving apparatus, and thus the type is not limited thereto.

4 is a flowchart illustrating a process of transmitting a real-time broadcast by a radio broadcast control system according to an embodiment. In detail, the wireless broadcast control system 100 interacts with the wireless broadcast request apparatus 200 and the wireless broadcast receiving apparatus 300 to perform wireless broadcast.

First, the user transmits a broadcast request message to the wireless broadcast control system 100 using the wireless broadcast request apparatus 200 (401). Specifically, the wireless broadcast request apparatus 200 may be implemented as a telephone capable of communicating with a public telephone, a mobile phone, a 070 telephone, or the like. At this time, the broadcast request message may be a specific character set in advance. For example, if * 1 # is sent, it can be a message requesting real-time broadcasting. If * 5 # is sent, it can be a message requesting a recording broadcast. Further, * 6 # may be a broadcast broadcast service, and * 7 # may be a message indicating a broadcast broadcast service. The description is illustrative, and the user can define a specific character between the wireless broadcast request apparatus 200 and the wireless broadcast control system 100 in various ways, and determine the corresponding function in advance.

The wireless broadcast control system 100 receives the broadcast request message and authenticates the user who transmitted the message (402). Since the broadcast request message includes the telephone number information of the wireless broadcast requesting apparatus 200 that sent the message, the broadcast request message can be authenticated by checking whether the broadcast request message corresponds to a telephone number of a person having a broadcast authority set in advance. If the user does not correspond to a person having a legitimate broadcasting right, the broadcasting service can not be provided, and the wireless broadcast control system 100 can notify the wireless broadcast request apparatus 200 of, for example, " Thereby responding to a wrong broadcast request message.

If the user corresponds to a person having a legitimate broadcasting right, the radio broadcasting control system 100 identifies a broadcasting request message (403). As described above, since character codes and corresponding functions are defined and synchronized in advance between the wireless broadcast control system 100 and the wireless broadcast request apparatus 100, for example, when the broadcast request message is * 1 # It is possible to make a reply call to the wireless broadcast request apparatus 100 (404). At this time, the reply telephone can be implemented by the CDMA method. In the case of real-time broadcasting, it means providing a function of a user who is a broadcasting right person to specify broadcasting contents in real time and broadcast. When the user specifies the broadcast content through the wireless broadcast request apparatus 100 by receiving a reply call (specifically, the user may be notified of the broadcast content by voice), the wireless broadcast control system 100 receives the broadcast content (405). Next, the wireless broadcast control system 100 can determine a transmission mode to transmit the broadcast contents (406). The broadcasting mode can be determined according to the broadcasting object. If the broadcasting mode corresponds to the entire broadcasting mode, the broadcasting mode includes both the outdoor broadcasting device and the in-home broadcasting device. Alternatively, only the outdoor broadcasting mode can be selected. In addition, in outdoor broadcasting, it is possible to decide whether to select a whole outdoor broadcasting device as a broadcasting object or a part of the outdoor broadcasting device according to a location where an actual outdoor broadcasting device is disposed, The user's receiving device may also be selected.

When the transmission mode is determined, the wireless broadcast control system 100 transmits the broadcast content to the wireless broadcast receiving apparatus 300 in the UHF (400 MHz) frequency band (407). The wireless broadcast receiving apparatus 300 can perform wireless broadcast by reproducing the received broadcast contents by voice.

4 is a case in which a broadcasting station requests real-time broadcasting. Accordingly, the present invention is not limited to the above-described embodiments, but may be embodied in various ways in each step by the practitioner. For example, if the number of broadcasts is set and transmitted in step 407 of broadcasting contents, the wireless broadcast receiving apparatus 300 may repeatedly reproduce the broadcast contents as many times as the number of broadcasts.

FIG. 5 is a flowchart illustrating a process of transmitting an emergency status broadcast according to another embodiment of the present invention. The wireless broadcast control system 100 may set an individual telephone number and a code value for the wireless broadcast receiving apparatus 200 in advance in order to receive an emergency situation request and broadcast a notification to the user in case of an emergency .

In another example of a case where an emergency occurs, an emergency call message is first received from the wireless broadcast receiving apparatus 300 (501). The emergency call message is sent in an emergency, and the user can be automatically configured to send a message if the emergency call is notified by using a specific emergency call device such as a pull string or a button provided in the wireless broadcast receiving device 300. Specifically, an emergency tone can be transmitted to the radio broadcasting control system 100 using a public telephone network (for example, a public switched telephone network (PSTN) communication network). That is, the tone is transmitted to the wireless broadcast control system 100 through the ordinary wired telephone. The tone may be implemented, for example, as a # 1 emergency or as a # 2 fire alarm. The emergency call message may include information of the wireless broadcast receiving apparatus 300. The information may be a telephone number of the wireless broadcast receiving apparatus 300 or a user identification code using a code number previously agreed with the wireless broadcast control system 100 in a message.

Next, the wireless broadcast control system 100 can identify the wireless broadcast receiving apparatus 300 by analyzing the emergency call message. For example, the identification information may be an individual telephone number and a tone of the wireless broadcast receiving apparatus 200 that transmitted the tone. Then, the broadcast contents can be set according to the emergency call message. Basically, you can set broadcasting contents with emphasis on the notification itself, such as "Emergency situation occurs with Hong Gil-dong". As another example, it is possible to set the contents of a broadcast with a notification content including a specific content such as "Fire at home of Hong Gil-dong ". The broadcasting contents can also be determined by analyzing code values defined between the radio broadcasting control system 100 and the radio broadcasting receiving apparatus 300 in advance in the emergency call message. Accordingly, the wireless broadcast control system 100 authenticates the sender and the code value, and then broadcasts the broadcast message to repeatedly broadcast the stored guidance message (504). At this time, the wireless broadcast control system 100 may select a broadcast object to transmit a broadcast, or may be a wireless broadcast receiving device provided by a specific organization (for example, a police station, a hospital, a fire station, etc.) An outdoor broadcasting device and an indoor receiving device located within a predetermined distance from the area in which the situation occurs may be selected and determined as a broadcasting object. The practitioner of one embodiment may classify and predefine broadcast objects according to the type and characteristics of the emergency situation.

FIG. 6 is a flowchart illustrating a process of transmitting broadcast contents according to a request message according to another embodiment of the present invention. Referring to FIG. The wireless broadcast control system 100 may receive a broadcast request message (601), and may identify the user authentication and request message. According to the result of user authentication, if the user does not have a proper broadcasting right (602-No), the broadcasting is not performed and the process is terminated. Identifies the request message if it corresponds to a person with legitimate broadcasting rights (602 - YES). The next step may be determined according to various broadcast services provided by the radio broadcast control system. Specifically, if the request message is real-time broadcast, the user can send a reply call to the user (604) and receive the broadcast contents (605). If the request message is a recorded broadcast, the broadcast contents can be determined by selecting one of the recorded broadcast contents without calling the user (606). If the request message is time synchronization, time synchronization is determined by comparing the current time with a preset specific time (608).

If the broadcast contents are determined to be different (605, 606), broadcast contents can be sent out (607) and terminated. In the case of time synchronization, a time synchronization command may be transmitted (609) and terminated.

As described above, the wireless broadcast control system 100 determines contents of a wireless broadcast service by analyzing a user and a request message, and provides a wireless broadcast according to a predetermined process.
