FIG. 1 is a block diagram of a system for transmitting and receiving a workplace information according to an exemplary embodiment of the present invention. Referring to FIG.

Referring to FIG. 1, a network-based local information transmission system includes an administrator server 100 and a user terminal 115. The manager server 100 includes a repeater 105 and an antenna 110. The manager server 100, the repeater 105 and the antenna 110 will be described separately for convenience of explanation .

The manager server 100 is located in a specific business place (such as a department store, a baseball field, a public office, a financial institution, a hospital, a performance hall, a movie theater, etc.) The terminal 110 transmits the business site information such as event guide, facility utilization, and product related to the specific business site to the user terminal 115 through the antenna 110.

The administrator server 100 builds up various kinds of business site information databases provided to the user in advance.

The repeater 105 receives various kinds of workplace information from the manager server 100 operated by the business site, modulates the received service information, and transmits the modulated information to an antenna (not shown) through a coaxial cable or an optical cable (Hereinafter, referred to as a bundle signal) to the terminal device 115 carried by the user.

At this time, when the terminal device 115 carried by the user is a dedicated terminal device according to the present invention, a radio frequency of about 2.45 GHz can be applied, and when a general mobile communication terminal is applied, The frequency band used for communication can be applied as it is.

The terminal device 115 receives a sum signal transmitted from the antenna 110, demodulates the received sum signal, and outputs a demodulated business site information through a receiving adapter function (including a storing and inquiring function) .

Here, the terminal device 115 may be a dedicated terminal device that performs only the above-described function of the receiving adapter. Preferably, the terminal device 115 may be a mobile communication terminal, a personal digital assistant (PDA) Can be attached or mounted. The description of the terminal device 115 is similarly applied in the following.

At this time, the repeater 105 adjusts the output of the bundle signal broadcasted through the antenna 110 so as not to exceed the range of the limited space (for example, the entrance of the department store) and transmits it to the user terminal 115 So that the effective reach can be adjusted as much as possible.

The contents of the present invention will be briefly described as follows. At this time, the business is assumed to be a department store.

First, a department store has an administrator server 100, a repeater 105, and an antenna 110. In addition, the antenna 110 is installed in advance at the entrance of the department store (at this time, the antenna 110 can be included in the repeater).

The manager server 100 transmits a bundle signal including various shop information such as a department store guide, an event event, a facility use, and the like through a repeater 105 and an antenna 110 to a user who passes through an entrance of a department store Device 115). ≪ / RTI >

Then, the user's terminal device 115 receives the bundle signal broadcasted from the antenna 110. Here, the reception is performed through the reception antenna provided in the terminal device 115. [ The terminal device 115 includes a storage and inquiry function for the received business information.

Thereafter, the user can utilize the department store while inquiring various business site information such as department store guidance, event promotion, and facility use by using the terminal device 115.

Here, the business information to be transmitted to the user terminal 115 may be stored in advance in the database, and may be provided to the user according to a predetermined time. Preferably, Lt; / RTI >

In this case, a specific user can visit a plurality of sites according to the present invention. In such a case, a unique code may be included in the site information to distinguish each site.

Hereinafter, the contents of the present invention, which are schematically described above, will be described in detail with reference to the drawings.

FIG. 2 is a flowchart illustrating a method of providing various types of business information related to a place to a user terminal when a user carrying a terminal device having only a receiving adapter function according to an exemplary embodiment of the present invention visits a specific place FIG. Referring to FIG. 2, in step 200, the administrator server 100 constructs various business site information databases related to the business sites to be provided to the user terminal 115 in advance. At this time, various business site information means, for example, in the case of a department store, regarding new products, events, store guidance, facility use, and the like.

In step 205, the manager server 100 continuously checks the time and proceeds to step 210.

In step 210, the manager server 100 determines whether the service start time has come on the basis of the time checked in step 205. If it is the service start time, the manager server 100 proceeds to step 215, otherwise proceeds to step 260.

Here, the service start time means a start time for providing various workplace information to a user at a specific workplace. For example, in the case of a department store, sales start from 10:00 am, in which the sales start time of the department store becomes the service start time.

In step 215, the manager server 100 searches the business information to be provided to the terminal 115 of the user according to the determination result of the service start time in step 210.

In step 220, the manager server 100 transmits the business information searched in step 215 to the relay device 105.

In step 225, the relay device 105 receives the business information transmitted by the manager server 100 in step 220, and proceeds to step 230.

In step 230, the relay device 105 modulates the received business information in step 225, and proceeds to step 235.

Then, in step 235, the repeater 105 broadcasts the modulated site information in step 230 to the bundle signal through the antenna 110 connected with the coaxial cable or optical cable.

Here, the antenna means a directional antenna, and the directional antenna refers to an antenna having a characteristic in which a radio wave is strongly radiated only in a specific direction, or a sensitivity is increased with respect to a radio wave coming from that direction.

For example, from step 225 to step 235, assume that the antenna 110 is installed at the entrance of the department store.

The repeater 105 receives the business site information including the store guidance, the goods, the facility use and the event from the manager server 100, modulates the received business location information, and transmits the modulated information to the coaxial cable or optical cable And broadcasts it as a compressed signal through an antenna 110 connected to the antenna.

Here, it is possible to arbitrarily determine a specific bit string as a constellation recognizing signal for allowing the terminal device 115 to recognize a constellation signal including business site information provided by a specific business site. For example, '0101001' I can decide.

At this time, the business site information provided by the administrator server 100 is divided into small packets and transmitted. That is, the data corresponding to the workplace information is not transmitted at one time but divided into several pieces, and each of them is packetized and broadcasted.

In step 240, the user receives an arbitrary radio frequency signal using the portable terminal device 115.

In step 245, the terminal device 115 determines whether the signal is a positive signal based on the RF signal received in step 240. If the signal is a positive signal, the terminal device 115 proceeds to step 250. Otherwise, the terminal device 115 continues to stand by .

For example, in step 245, in determining whether the user's terminal device 115 is a broadcast signal broadcasted from an antenna (for example, a directional antenna) 110 installed at an entrance of a business site such as a department store or the like, (For example, a specific bit string) (hereinafter, referred to as a bundle identification signal) transmitted from the repeater 105 to determine that the corresponding bundle signal is being transmitted.

The above contents will be described again in comparison with a general mobile phone.

In a CDMA system, in the case of a general mobile phone, data is transmitted through four channels. The four channels at this time are the pilot channel, the sink channel, the paging channel, and the traffic channel.

Basic settings are made with the base station in the pilot channel, basic synchronization work is performed through the sink channel, simple information and control information are transmitted through the paging channel, and voice and data are transmitted through the traffic channel.

That is, in the CDMA system, the mobile station receives the pilot channel of the base station, selects the base station, receives the synchronization channel of the base station and synchronizes the received pilot channel, and receives the mobile communication service through the traffic channel.

However, the jersey signal according to the present invention notifies that the bundle recognition signal is being transmitted through the pilot channel, and the business information is transmitted through the traffic channel.

That is, the repeater 105 applies a specific bit string as the bundle recognition signal when broadcasting the bundle signal to the user's terminal device 115. Since the specific bit string at this time is unique information for allowing the terminal device 115 to recognize the bundle recognition signal, the terminal device 115 interprets the specific bit string and judges whether it is a bundle signal.

The case where the terminal device 115 receives the above-mentioned business site information will be described as follows.

The repeater 105 broadcasts the bundle signal including the business site information through the antenna 110, and the terminal device 115 continuously receives the business site information until the business site information provided at the business site is received.

In other words, the business site information is not transmitted at one time, but is divided into several pieces, each of which is packetized and transmitted. Thus, once all of the packetized business location information is received, the business location information is no longer received. In other words, duplicate business information is not received.

An identification code included in the bundle signal can be used for not duplicating the business site information. The identification code may be a time stamp indicating a modification date and time of the business information.

At this time, preferably, the identification code may be at least one of a number, a letter, or a combination of a number and a letter to recognize whether or not the business information is updated.

In this way, the terminal device 115 checks whether the business information extracted from the bundle signal transmitted from the relay device 105 through the antenna 110 has already been received or newly updated, using the identification code, And does not receive business information that is not received.

Preferably, each packet does not include an identification code indicating whether or not the business information is updated, and after all the business information is received, the information is compared with all the business information stored in advance and stored if it is new business information, .

The receiving terminal device 115 will be described in detail as follows.

The terminal device 115 includes a control table, an operating system (OS), and a memory.

The operating system performs memory allocation, control table management, memory management, and user input / output management of data included in the compressed signal.

The control table stores information for memory management and determination of whether or not to receive data, and stores information such as a location of a root node indicating a storage location of data, an unlock value of an initial value of data, A lock ID indicating the movement of data to the lock data area of the memory, a business ID, a time stamp, and a total number of data.

The memory includes a control information block which is a temporary information storage area, a buffer area which is a primary storage area of received data, a general storage area which stores information in a logical circular queue form, lock data by user request, And a lock data area for storing the data.

In step 250, the terminal device 115 demodulates the received jersey signal according to the result of judging that the arbitrary radio frequency signal received in step 245 is a jersey signal.

Preferably, transmission and reception of packets corresponding to the sum signal do not necessarily have to be performed in order from the first packet. Any packet may be demodulated and stored in any order, and then repeatedly received until all packets are received. .

In addition, the terminal device 115 can additionally receive and receive packets that are not received due to an exceptional interference (noise or the like) in the process of receiving a packet for the first time, There is a number.

Here, the deletion of the duplicate received packet is performed by searching the time stamp included in the packet (recording the generation and modification date and time of data), determining whether the received packet is already received, updating the data included in the packet, Otherwise, it can be deleted.

The above description can be similarly applied to the following.

In step 255, the business information such as the department store demodulated through the above process is displayed on the display device of the terminal device 115. The terminal device 115 may include a storing and inquiring function for the business information such as the department store.

In step 260, it is determined whether the service end time has come. If the time has not come, the process proceeds to step 205, and if the time comes, the process is terminated.

The present invention can be applied to the case where the administrator server 100 uses the antenna 110 installed at the entrance of a specific business site and uses the built-in business entity information stored in advance in the terminal device 115 carried by the user, It is assumed that the signal is broadcast repeatedly and continuously.

Preferably, however, a plurality of dispatchers 110 may be installed in the workplace as well as at the entrance of the workplace to store a premix signal including newly-updated information, . This can be similarly applied to the following.

FIG. 3 is a flowchart illustrating a method of providing various types of service information and emergency information to a terminal of a user visiting a specific place according to a preferred embodiment of the present invention.

Hereinafter, the user terminal 115 will be described on the assumption that a dedicated terminal including a receiving adapter function is attached to or attached to a mobile communication terminal. For convenience of description, the parts that will be described in conjunction with FIG. 2 will be omitted.

Referring to FIG. 3, in step 315, the administrator server 100 searches the business information database and proceeds to step 320.

If the business site information database is related to a baseball field, the business site information database may include game related information such as an athlete, prize, weather, and the like that can be provided to a user carrying the terminal device 115 such as a mobile communication terminal Can be stored.

In step 320, the administrator server 100 determines whether new input information (for example, emergency news) is received during the search of the business information in step 315. If new input information is received, the manager server 100 proceeds to step 325, Otherwise, the process proceeds to step 330

In step 325, the manager server 100 transmits new input information (for example, urgent news, etc.) to the relay apparatus 105 in accordance with the result of determination in step 320 that new input information has been received.

For example, from step 325 to step 330, when an administrator needs to deliver a game breaking news or breaking news in addition to the information stored in the database to the user (meaning crowd), the manager server 100 sends a new game breaking notice Or breaking news, etc., and the manager server 100 transmits the received input information to the relay device 105. [

In step 330, the manager server 100 transmits the information stored in the business site information database to the relay 105 in advance according to the determination result in step 320.

In step 335, the relay device 105 receives the business information transmitted by the manager server 100 in step 330, and proceeds to step 340.

In step 340, the repeater 105 modifies the received business location information in step 335, and proceeds to step 345.

Then, in step 345, the repeater 105 broadcasts the modulated business site information in step 340 to the bundle signal through the antenna 110 connected by a coaxial cable or an optical cable.

Here, the antenna means a directional antenna, and the directional antenna refers to an antenna having a characteristic in which a radio wave is strongly radiated only in a specific direction, or a sensitivity is increased with respect to a radio wave coming from that direction.

For example, from step 335 to step 345, assume that the antenna 110 is installed at the entrance of a baseball field.

The relay 105 receives the guide information, the product information, the competition information, the event information, and the like from the manager server 100, demodulates the received information, and transmits the demodulated baseball field information through the coaxial cable or the optical cable (110) to the user's terminal (115).

Thereafter, in step 350, the user receives an arbitrary radio frequency signal using the terminal device 115 such as a mobile communication terminal or a personal digital assistant (PDA).

In step 355, the terminal device 115 determines whether it is a call paging signal (a signal for a general telephone call) based on a certain radio frequency signal received in step 350 and proceeds to step 360 if it is a paging call signal, Proceed to 365.

That is, the terminal device 115 can receive a call paging signal from the base station of the mobile communication service provider.

In step 360, the terminal device 115 maintains a standby state for receiving a certain signal after performing the call service according to the determination result that the signal received in step 355 is a call paging signal.

In step 365, the terminal device 115 determines whether the received signal is a broadcast signal broadcasted by the antenna 110 of the corresponding workplace, according to a result of the determination in step 355 that the received signal is not a call paging signal.

In step 370, the terminal device 115 demodulates the radio frequency signal according to the result of judging that the arbitrary radio frequency signal received in step 365 is the sum signal.

For example, steps 365 to 370 will be described in detail.

In order to use the existing hardware of the mobile phone terminal, all the people entering the business place through the PN code for virtual broadcasting can receive the bundle signal at the same time.

In other words, in the CDMA system, the PN code includes a Short PN code and a Long PN code. The short PN code is used for recognition between the base stations, and the long PN code is synthesized and transmitted to the data to be actually transmitted.

Therefore, in the present invention, modulation and demodulation of transmission data is performed using the above-mentioned Long PN code (hereinafter referred to as PN code). That is, the terminal device 115, which has confirmed that the bundle recognition signal is being transmitted through the pilot channel, receives the original PN code used in the CDMA system in order to receive and demodulate the bundle signal, ), And demodulates the sum signal using the converted PN code for constellation.

After completing the above processing, the terminal device 115 converts the PN code for suspending to the original PN code again.

Accordingly, the present invention can be applied to a general cellular phone (particularly, a cellular phone) used in a CDMA system without any hardware modification through the above process as a receiving and inquiring apparatus.

In step 375, the terminal device 115 displays game information on the demoted baseball field and the like on the display device of the terminal device 115 through the above process. Preferably, the terminal device 115 may include a storage function and an inquiry function for the game information on the baseball field or the like.

In step 380, it is determined whether the service end time is reached during the above process. If the service end time is reached, the process is terminated. Otherwise, the process is repeated in step 305.

4 is a configuration diagram of a dedicated terminal apparatus having a function of a receiving adapter for receiving and processing a bundle signal transmitted from an antenna according to a preferred embodiment of the present invention.

4, the dedicated terminal 400 includes a receiving unit 405, a demodulating unit 410, a controlling unit 415, a storing unit 420, and a display unit 425.

The receiving means 405 may include an antenna and the like. The receiving means 405 receives the sum signal transmitted from the antenna 110, amplifies the received sum signal, and transmits the amplified sum signal to the demodulating means 410.

The demodulation means 410 demodulates the compressed signal received through the reception means 405 into digital information and transmits the demodulated digital information to the control means 415. [ Digital information at this time refers to various kinds of business information (such as department store information and baseball field information) to be provided to the user from the business site.

The control means 415 stores the digital information received from the demodulation means 410 in the storage means 420. Preferably, the control means 415 may display the received digital information (various kinds of service information) on the display means 425 in real time.

Thereafter, the user can inquire and retrieve the stored information on the basis of a predetermined input key or the like when the user wants to use the information stored in the storage means 420.

5 is an exemplary diagram illustrating a layer model of a network architecture according to an exemplary embodiment of the present invention.

Referring to FIG. 5, a layer model 500 includes an application layer for data transmission, a transport layer for datagram transmission, a packet transmission And a radio frequency baseband (RF baseband) layer.

The application layer performs data structuring, control data processing, error detection, etc., and the transport layer performs processing of duplication of datagrams, compression processing, error detection, etc., and the radio frequency baseband layer Packet synchronization, and whether to accept the packet.

Such protocols are characterized by non-connectivity, unreliability and unidirectional transmission.

The reason why the protocol has characteristics of non-connected, unreliable and unidirectional transmission is that the antenna transmits the object without specifying it.

Specifically, it is unreliable because it does not confirm whether or not the connection to the reception terminal apparatus 115 is connected, and therefore, it is non-connectable and continuously transmitted without confirming whether or not it is received according to data transmission. Since the protocol does not support bi-directional communication with the reception terminal apparatus 115, it has a unidirectional characteristic.

6 is a diagram illustrating a data structure according to an exemplary embodiment of the present invention.

Referring to FIG. 6, an application layer forms a data code composed of a data head, data and a checksum as a first data structure 600, and a transport layer includes a first data structure 600 form a second data structure 605 as a data code encapsulated with a datagram header and a checksum.

And the radio frequency (RF) baseband layer is composed of actual packets and sent.

FIGS. 7A and 7B are diagrams illustrating screens displayed on a terminal device of a user according to an exemplary embodiment of the present invention.

Hereinafter, for convenience of description, FIGS. 7A and 7B will be described together. 7A and 7B, an initial screen example 700 of service information provided by the administrator server 100 to the user terminal 115 includes a store information item 705, an event information item 710, A recommendation item item 715, a next screen item 720, and a main screen item 725, and the like.

If the user selects the store guidance item 705 in the initial screen example 700 of the service information output to the terminal device 115, the terminal device 115 may include a floor guide, a brand guide, Print the item on the screen.

If the user selects the floor guide item again, the terminal device 115 outputs the map of the corresponding floor, the brand guide of the floor, the convenience facilities of the floor, and the like.

When the user selects the recommended product item 715 in the initial screen example 700, the product information shown in FIG. 5B is displayed on the screen of the terminal device 115.

At this time, the displayed product information is an image of the product and an introduction to the product. For example, the display information is sold at a discount of 50% for 10 new products of Rogatis only in the 4th floor of the men's clothing store. Quick haste, it is not much left. ' Or the like, on the screen of the terminal device 115.

7A and 7B can be hyperlinked, can display and display various contents (such as text, graphics, and sound), and can represent a hierarchical structure. For this expression, the HDML (Handheld Device Markup Language (WML), and Wireless Markup Language (WML).

Each information displayed on the terminal device 115 has a hierarchical structure such as a directory structure.

Wireless Markup Language (WML) is based on XML (eXtensible Markup Language) for input and display on mobile communication terminals such as wireless telephone and personal digital assistant (PDA) It is a markup language that has been developed. Such a WML language is suitable for a mobile terminal having a small screen, a limited memory, a CPU, a low bandwidth, and a long latency of connection.

And the Handheld Device Markup Language (HDML) is a language created to connect to the Internet in a mobile communication terminal whose memory, screen size, and input method are relatively smaller than the desktop.

Therefore, according to the network-based local information transmission system and method according to the present invention, the user can receive various information such as event information, event site information, product information, and the like through the network, thereby reducing discomfort caused by distribution of flyers, And so on.

Then, the business operator can transmit various information related to the place such as the product information to the user based on the network, thereby preventing the occurrence of the garbage, thereby building an image as an environmentally-friendly enterprise.

In addition, the operator can reduce the production cost of leaflets or pamphlets for delivering service information and the like to the user, thereby enabling stable and efficient financial operation.
