In particular, the present invention relates to a content downloading system and a content server system and method for controlling traffic according to a capacity of a content and a load of a system.

The mobile communication system provides a basic service for communicating voice signals to a subscribed portable terminal while developing various supplementary services.

Examples of the additional service provided by the mobile communication system include wireless Internet, TV watching, online game, mobile chat, and the like. Particularly, the message service is an additional service that is recently activated.

The message service includes a voice message using a voice signal and a text message using character data. The digital message of the mobile communication system and the high-speed data transmission are available, and a multimedia message service including a video signal is being activated.

In addition, due to the development of technology related to portable terminals, functions are advanced and models of various specifications are introduced.

Since a code division multiple access (CDMA) mobile communication system basically includes a function of providing a text message service, the text message data processing and transmission / reception specifications are the same in all systems.

However, in the case of the multimedia message service, the data processing standards and the method are different for each service provider operating the mobile communication system, and the multimedia message (hereinafter, contents) generation and reproduction specifications are different for each portable terminal.

For example, in the case of an audio signal of a content, the number of synthetic sound sources or chords used for reproduction is 16, 32 or 64, and the number varies depending on the type of portable terminal. In the case of a video signal, There is a difference in the method, and a difference in reproduction standard or the like occurs due to the number of picture element unit pixels (PIXEL).

Therefore, the multimedia contents transmitted and received between the portable terminal of the service provider and the mobile communication system different from the reproduction standard must be converted to be reproducible on the receiving side.

Generally, a packet (PACKET) data communication method is used for content transmission in the mobile communication system.

There is an MTS (MULTIMEDIA TRANSCODER SERVER) server for converting the contents to a reproduction standard of the receiving-side portable terminal.

Since the contents can easily convey a lot of information to be transmitted, it is often used by the event company for the purpose of publicity, advertisement, guidance, and the like.

A virtual multimedia message gateway (VMG) device is used for transmitting contents having the same contents to a specified multiple mobile terminals and utilizing the contents as event messages.

The VMG device manages whether the receiving side mobile terminal only receives a text message or receives multimedia contents, checks and converts the video signal and the audio signal reproduction standard or specifications of the receiving side, and outputs the selected MDD (MOBILE DIRECTORY NUMBER To be transmitted to the mobile terminal of the mobile terminal.

The mobile communication system requests the mobile terminal of the MDN to receive the content, and when the mobile terminal is ready, the mobile terminal downloads and provides the converted content suitable for the reproduction standard.

At this time, since a call for requesting contents reception is set to the portable terminal by the MDN, a traffic congestion occurs, a traffic congestion occurs due to a content download request of the portable terminal, and a load increases .

1, when a mobile communication system determines that there is a request to send a content to a plurality of MDNs (S10), the content information is transmitted to a large number of mobile terminals And inputs the MDN information which is the terminal phone number (S20).

The content information is converted into a reproduction standard of the portable terminal to be received (S30), and the converted content is sent to the input MDN in a downloading manner (S40).

As described above, in the case of the large-capacity transmission in which the same content is transmitted to a plurality of portable terminals, the content is simultaneously transmitted to the portable terminal of the input MDN, so that traffic is temporarily congested in the system, there is a problem.

In order to solve the above problem, an improved conventional technique of reducing the temporary load increase of the system is introduced because the whole MDN is divided into a certain size and the content is sent in units of MDNs divided.

However, even in the improved prior art, there is a problem that the problem of the traffic congestion and the load of the system being increased due to the increase of the capacity of the content transmitted through the downloading method can not be solved.

The present invention examines the download time of contents by the data size to determine the number of MDN constituents in the transmission group and monitors the download load to adjust the number of transmission groups in case of an overload state. And a content server system and a method for operating the content server.

According to an aspect of the present invention, there is provided a mobile communication system including: a mobile terminal for downloading and playing a content according to a request for receiving a mobile communication system; A mobile communication system for requesting reception of a content from a portable terminal and downloading a content converted into a reproduction standard by a download request in a normal load state of a download server at a delay time interval for each sending group; A content server system for testing the downloading time of the content by controlling the mobile communication system, determining and downloading the number of the sending group, and adjusting the number of the sending group when the load of the downloading server increases; A content download system configuration is proposed in which a large number of MDN numbers and content information are input to a mobile communication system and a content server system to request an event to be transmitted.

Hereinafter, a content download system and a content server system and an operation method according to the present invention having the above-described configuration will be described with reference to the accompanying drawings.

2 is a functional block diagram of a content download system according to the present invention, FIG. 3 is a flowchart of an operation method of a content download system according to the present invention, FIG. 4 is a flowchart FIG. 5 is a detailed block diagram of the server apparatus according to the present invention, and FIG. 6 is a flowchart illustrating an operation method of the content server system according to the present invention.

Referring to FIG. 2, the portable terminal 100 wirelessly connects to a mobile communication system 110 through a channel allocated in a service area formed by a base station device of the mobile communication system 110, Lt; RTI ID = 0.0 > 110, < / RTI >

The SMS NOTIFICATION information includes URL (UNIFORM RESOURCE LOCATOR) address information, so that the contents can be downloaded.

For example, the portable terminal 100 reserves a self-operated memory area for recording a content to be downloaded, suspends a service in operation, or performs a task (TASK) application in which importance or priority is low And to delay the operation of programs.

The mobile terminal 100 ready for download requests the mobile communication system 110 to download the corresponding content.

A content is a multimedia message including a voice, a character, and a video signal. The multimedia message includes a large amount of information and can easily confirm information contents to be transmitted only by viewing or listening.

The content requested to be received by the mobile terminal 100 through the mobile communication system 110 may be information transmitted by search or reservation or may be information transmitted by the event company 140 such as advertisement, Information transmitted for the purpose, and so on.

The event server 140 creates or generates the corresponding contents and transmits the contents of the mobile communication system 110 connected via the public network 130 including the Internet together with the number of the portable terminals or MDN (MOBILE DIRECTORY NUMBER) Or the content server system 120 and requests transmission.

The MDN number (telephone number) information of the portable terminal, which the event server 140 inputs at one time for content transmission, may be from tens of thousands to hundreds of thousands or millions, for example. In the system 120, a large amount of content is transferred.

The mobile terminal 100 has a wide variety of models due to the development of manufacturing technology.

For example, a CCD (Charge Coupled Device) can be used, or an image pickup device of a camera that captures a video signal can use a C-MOS (COMPLEMENTARY METAL OXIDE SEMICONDUCTOR) 1 million pixels and so on.

There are VGA (Video Graphics Array) method and CIF (COMMON INTERMEDIATE FORMAT) method for processing a frame-based video signal for recording an image signal captured and input by an imaging device.

Particularly, in one portable terminal, it is general that a video signal processing method, that is, a recording standard and a playback standard are the same.

The VGA method was announced by IBM in 1987 and is now adopted as the basic standard for monitors in many computers.

The resolution of the VGA system depends on the number of colors displayed. For example, a resolution of 640 * 480 pixels (PIXEL) can represent 16 colors. To use 256 colors, the resolution must be reduced to 320 * 200 pixels .

In addition, the CIF method is a video signal processing method of a video conference system, and supports NTSC and PAL, and supports a data transmission rate of 30 frames per second. Each frame is composed of 352 pixels and 288 lines.

Related to the CIF method, QCIF (QUARTER CIF) transmits 1/4 data amount and is suitable for video conference data transmission using a telephone line, and CIF is called FCIF (Full CIF) for distinguishing from QCIF.

There is a high end model and low end model on the cost side of the mobile terminal. In general, VGA type lens assembly (ASSY: ASSEMBLY) is used for high price and CIF type lens assy And the like.

Since the models of portable terminals to receive and reproduce the contents created or generated by the event maker 140 are various and their playback standards are different, the contents must be converted and transferred to the playback standard of the portable terminal.

The content server system 120 records and updates the model type and related standard information of all the mobile terminals 100 subscribed to the mobile communication system 110 into a database, updates (UPDATE) do.

In addition, it has an MTS server function for converting the original contents into the reproduction standard of the receiving-side portable terminal 100, and records the contents converted by the MTS server function in the allocated area.

That is, the content server system 120 confirms the portable terminal playback standard of the MDN input by the event server 140 as the content transmission object, converts the input content into the confirmed playback standard, and transmits the converted playback standard to the portable terminal 100 do.

When the content converted into the playback standard is transmitted to the portable terminal, the content server system must include a server for managing the download (D / L) since the download method is used.

In addition, the present position of the portable terminal of the MDN as a target of contents transmission is checked, and when the mobile terminal is out of the service area, it is excluded from the call connection object, thereby preventing traffic congestion and reducing communication cost.

The mobile communication system 110 has to confirm the current position of each mobile terminal in the movement for the call connection processing of the path setting to communicate with the mobile terminal 100. The mobile communication system 110 records and updates the confirmed position information, If requested by the server system 120, it is provided immediately.

In other words, the event maker 140 aims to notify the portable terminal 100 of a very large number of MDNs simultaneously and rapidly.

In addition, the mobile communication system 110 is required to respond to a call connection request of a general subscriber while limiting the number of simultaneous call connection establishments to the mechanical switching processing capability of the mobile switching center.

Therefore, the number of call connections in which the event-like contents are simultaneously transmitted by the operator or manager of the mobile communication system is within a range of long-term experience or experimentally secured, and it prevents the congestion of the temporary traffic, Is limited to the extent to prevent the occurrence.

When the mobile communication system 110 requests the mobile terminal 100 to receive the content, the traffic is generated even when the traffic TRAFFIC occurs and the download request signal is received from the mobile terminal ready for downloading.

Also, in the case of a download server providing contents, when there is a download request from many portable terminals at once, an increase in load may cause an error or a shutdown phenomenon in which the operation is stopped.

That is, if the mobile communication system needs to maintain and manage the traffic for requesting reception of content and the traffic caused by the content download request of the mobile terminal so that the error due to congestion does not occur, It is a technique to solve the need.

A method of operating a content download system according to the present invention will be described in detail with reference to FIG.

If there is a content transmission request from the event server 140 (S100), the mobile communication system 110 inputs content information to be transmitted and a large amount of MDN number information (S110).

The mobile communication system 110 controls the content server system 120 to record the input content and the MDN information in the allocated areas and analyze the size of the content (SIZE) (S120).

In analyzing the size of content to be transmitted, the selected portable terminal is designated as a test portable terminal, the content is converted into a content conforming to the playback standard, and downloaded to the test portable terminal through the download server.

When the test portable terminal has completed the downloading of the content, the download server is controlled to measure the time required for the download.

By analyzing the download time thus measured, a call connection number that can simultaneously request to receive the content in the mobile communication system is estimated.

The estimated number is a number that can send out the MDN at a time, and is specified and determined by the number of the sending group.

The content server system 120 under the control of the mobile communication system analyzes the inputted large amount of MDN number information and classifies and arranges the information according to the model type of the portable terminal at step S130.

That is, the large number of MDN numbers include mobile terminals based on the same model.

The content server system 120 checks each reproduction standard for each model type of the portable terminal, converts the original content so that the original content can be reproduced by the portable terminal of the corresponding model, and sequentially divides the original content into the transmission group S140).

The content server system 120 requests the mobile terminal of each MDN number constituting the sending group to receive the content by SMS NOTIFICATION by controlling the mobile communication system.

If there is a download request from each portable terminal of the MDN, the download server is controlled, so that the content converted into the reproduction standard is controlled and monitored through the mobile communication system in accordance with the set order of the transmission group to the portable terminal S150).

If the delay time is counted, the load value of the download server is detected, and if it is larger than the set threshold value, that is, It is checked whether the normal load LOAD is operated (S170).

When the download server is not operated as a normal load, the number of the sending group is designated and determined by a number obtained by subtracting a predetermined numerical value set from the designated and determined number as the sending group, and FEEDBACK is sent to the sending process (S140) S180).

For example, every time it is confirmed that the download server is overloaded, the number of the sending group is reduced by subtracting 10 from the number specified as the sending group, thereby reducing the load on the download server while reducing traffic in the mobile communication system.

When the download server is operated under normal load, the content server system 120 checks whether the transmission of the content converted into the playback standard has been completed in the entire MDN. If the download is not completed, the content server system 120 proceeds to step S140, FEEDBACK). If the transmission is completed, the process proceeds to the end (S190).

Therefore, the present invention having the above-mentioned configuration controls the number of the sending groups notifying SMS NOTIFICATION in the mobile communication system, thereby controlling the outbound traffic congestion and indirectly controlling the load of the download server, .

In addition, since the input MDN information is analyzed, the content is classified according to the model of the portable terminal, and the converted content is transmitted according to each type of playback standard, the processing time is saved and transmitted quickly.

4 and 5, the content server system 120 includes a VMG apparatus 200, a download server 300, and a server apparatus 400.

When a large amount of MDN information is received, the VMG device 200 measures the download time through the test portable terminal, determines the configuration number of the sending group, and divides the group into the sending group by type VMG memory 210, VMG memory 220, and VMG database 230 for controlling and monitoring the converted MDNs so that the converted contents are downloaded.

The VMG server 210 inputs the original content to be received and records the original content in the MMS server 420 of the server device, and the MDN information that is input together with the original content is stored in the VMG memory 220 area.

In addition, the download server 300 may measure the load value generated when downloading the content converted into the playback standard by the request of the portable terminal of the MDN, compare the set threshold value (THRESHOLD VALUE) with the measured load value, If it is confirmed, the number of MDNs constituting the sending group is controlled to be reduced by a predetermined unit.

In addition, the input MDN information is classified according to the model type of the mobile terminal, the mobile terminal is arranged in units of the sending group, the SMSNTIFICATION request is received to the MDN mobile terminal of each sending group in units of delay time, And controls the MDN portable terminal of the next sequential sending group to request the content reception.

Under the control of the VMG server 210, the VMG memory 220 stores a content signal converted into a content reproduction standard for each model type of the MDN portable terminal and a large amount of MDN information input by the event history 140, And at the same time records information used for content transmission.

Under the control of the VMG server 210, the VMG database 230 stores content playback standard information, delay time value, set load threshold value of the download server 300, number information of the sending group And so on.

The download server 300 transmits the contents to the test portable terminal under the control of the VMG device 200 to measure the downloading time and requests the respective MDN portable terminals of the sending group to receive the contents by SMS NOTIFICATION, And transmits the converted content to the MDN portable terminal requesting the download in a downloading method.

The server 400 includes an MTS (MULTIMEDIA TRANSCODER SERVER) server 410, a MULTIMEDIA MESSAGE SERVER (MMS) server 420, and a location server 430.

The MTS server 410 receives the original content and the reproduction standard information under the control of the VMG device 200 and converts the content so that the mobile terminal of the reproduction standard can reproduce the content without error.

The multimedia (MMS) server 420 records the original content under the control of the VMG device 200, and performs general multimedia message creation and playback processing of the received multimedia message.

The location server 430 searches the current location of the mobile terminal and confirms whether or not it is located in the service area. When each mobile terminal is out of the service area by a large MDN, And reduces unnecessary communication costs of the event company.

Referring to FIG. 6, FIG. 2, FIG. 4, and FIG. 5, a method of operating a content server system according to the present invention will be described in detail.

The VMG apparatus 200 constituting the content server system is an event sender 140 or an application server through the mobile communication system 110, and receives contents transmission request information (ST 200).

The contents transmission request information includes contents to be transmitted, portable terminal number based on a large amount of MDN, time information requesting transmission, and the like.

The VMG apparatus 200 records the original content information in the multimedia information (MMS) server 420 and the large amount of MDN portable terminal number information in the VMG memory 220 area.

To control the traffic to transmit the input contents to the mobile terminal 100 of the designated MDN without traffic congestion and overload of the mobile communication system 110 and the content server system 120, .

That is, the VMG device 200 requests the test portable terminal 100 to receive the content using the SMS NOTIFICATION information (ST210), and transmits the request message to the VMG device 200 by the test portable terminal 100 And requests download of the content (ST220).

The VMG apparatus 200 confirms the reproduction standard of the portable terminal requesting the download and converts the content so that the content can be reproduced without error (ST 230).

(ST240). Then, the download server 300 downloads the content in the format specified in the test portable terminal 100 (ST250).

The downloading method includes a streaming method in which, when a part of the set size is downloaded from the entire data, the streaming continues to download the remaining data while the playback is started, and the downloading method in which the entire data is received after completion of reception.

The VMG apparatus 200 controls the download server 300 to measure the time required for completely downloading the content from the trial mobile terminal 100 without error (ST260).

The test portable terminal is not specially manufactured but is the same as a general portable terminal and is a portable terminal selected for testing.

The VMG apparatus 200 analyzes the measured download time to calculate a number that can maximally make a call connection simultaneously with no traffic congestion in the mobile communication system 110, Specify.

In addition, the portable terminals of the MDN are classified into models, and the shipping groups are sequentially sorted by the calculated numbers (ST270).

The mobile terminal 100 requests the MDN mobile terminal 100 of the corresponding sending group to receive the content by using the SMS NOTIFICATION in the sorted order (ST280), and receives the download request signal of the content from the portable terminal 100 (ST290).

The VMG apparatus 200 confirms the reproduction standard for allowing the content to be reproduced without error in the portable terminal type of the transmission group, and converts the content to conform to the reproduction standard (ST 300).

The contents converted into the reproduction standard of the sending group are transmitted to the download server together with the MDN information of the sending group and controlled to be transmitted (ST310).

The download server 300 downloads the converted content to the portable terminal 100 by the MDN of the designated sending group (ST320).

The VMG device 200 monitors the download server 300 to detect a load value, and confirms whether or not the load value is an overload state in comparison with the set threshold value (S330).

As a result of monitoring the load of the download server 300, if it is confirmed as an overload state, the configuration number of the sending group is adjusted to be decreased, and after the elapse of a predetermined delay time (DELAY TIME) Since the content is fed back to the monitoring process (ST280), it is repeated until the content download is completed to the entire input MDN (ST340).

Therefore, the number constituting the sending group unit is determined according to the time required for downloading the content, and when the load due to the content download increases by monitoring the download server, the unit number of the sending group is further reduced. Traffic congestion and load are reduced, and there is an advantage of indirect control so that the entire system operates stably.

The present invention having such a configuration has industrial effect of increasing the operation rate of the system by informing the maximum portable terminal to receive the contents while preventing the temporary traffic congestion of the mobile communication system when the contents signal is transmitted in a large amount.

Further, when a server for downloading a content by a request of the portable terminal is operated with an overload exceeding a threshold value, since the number of the sending group is variably adjusted by SMS NOTIFICATION SCHEDULER, the industrial use for indirectly controlling the load of the download server It is effective.

In addition, the phenomenon that the traffic of the mobile communication system is congested due to simultaneous occurrence of the call connection by the content request call connection and the content download of the mobile terminal is predicted and prevented by the load monitoring of the download server, There is an advantageous effect in use that increases the reliability.

In addition, since a large amount of MDN information is analyzed and classified into portable terminal model types, contents are converted and transmitted according to classified classified playback standards, so that it is possible to reduce the content conversion time and reduce the load on the system, It is effective.
