When the TCP connection is successfully established, the operating system 100a generates a socket associated with the TCP connection. In response to the socket creation request, the operating system 100a returns the identifier of the socket to the data transmission / reception unit 112 do.

When the identifier of the generated socket is returned, the transmission / reception control unit 112 transmits the request based on the communication protocol requested to be transmitted to the operating system 100a through the socket specified by the returned identifier, For example, to the content server 12, to the corresponding destination. Of course, the request at this time is transmitted as a signal corresponding to the physical communication resource (the Wi-Fi codec 2b / the Wi-Fi modem 2a) for the Wi-Fi network 11b currently connected do. The transmitted request is routed to the content server 12 by the associated communication networks and the content server 12 constructs a response to the request and transmits it to the wireless communication terminal 100 . The response provided by the content server 12 is received by the transmission / reception control unit 112 from the operating system 100a via the generated socket, reads the received response data, And transfers the data to the media processing unit 113. The transmission at this time may be performed through a memory space that is mutually shared between the transmission / reception control unit 112 and the media processing unit 113. For example, the transmission / reception control unit 112 may record data received in the memory space and transmit the head address of the recorded location to the media processing unit 113. The response received by the transmission / reception control unit 112 includes not only the media data (hereinafter, simply referred to as "content data") of the content file to be delivered to the media processing unit 113, (Mime type of the content file, file size, and the like) provided in accordance with the protocol format. The transmission / reception control unit 112 grasps the media information (the total play time of the content, etc.) from the head data of the received content data, and stores the meta data together with the file description information. The metadata for the currently stored content is also shared by the UI processing unit 111. In another embodiment of the present invention, the media processing unit 113 may write the media information obtained by decoding the corresponding content data into the corresponding information field of the metadata.

As described above, when the data is received for the remote content requested by the user's selection, the media player 110 transmits the content via the Wi-Fi network according to the flowcharts illustrated in FIGS. 3A and 3B, Displays expected data usage for the cellular network while receiving data, and performs an operation of temporarily receiving the content data through a plurality of communication networks by using the cellular network, if necessary. This operation will be described in detail below.

When a response to the request for content is received from the operating system 100a (S301), the transmission / reception control unit 112 transmits the content data to the media processing unit 113 in the received response, And counts the total reception amount for the data. During the counting of the total reception amount, the transmission / reception control unit 112 classifies the amount of data received by the communication network on which the data is received and ascertains the amount (of course, in the present case of receiving the content data using only the Wi-Fi network, The total amount received is the usage for the Wi-Fi network.) Since the communication network to be used by the socket is specified at the time of creation of the socket, the amount of data received through the sockets classified by the use network is counted, and the total reception amount of each communication network and the total reception The amount can be grasped. Also, the transmission / reception control unit 112 continuously measures the service speed for the access point of the currently connected Wi-Fi network by counting the amount of data received through the socket created for use of the Wi-Fi network ( S302). In one embodiment according to the present invention, the average of the service rates measured several times may be used as the service rate for the current access point. (For example, 100 msec, or 200 msec, etc.) during the progress of the delivery of the received content data to the media processing unit 113 and the service speed measurement operation of the current access point (S303), and notifies the UI processing unit 111 of the service speed of the currently measured connection point (S311). When the reception of the content data from the remote place is started, the state check period is set to the transmission / reception control unit 112 as a predetermined time period. By driving a timer corresponding to the set time period, It is possible to know whether it corresponds to the status check cycle.

As one method of measuring the service speed provided by the connected current access point, the transmission / reception control unit 112 controls the transmission / reception of the Wi-Fi network to use the Wi-Fi network with the operating system 100a, The amount of media data to be transferred to the shared memory 42 which is received via the generated socket 41 and which is a data space for transferring to the media processing unit 113 is set to a predetermined time width T _int , And measures the data reception rate at the present time. In the example of the figure, (dB _M + dB _{M + 1} + dB _{M + 2} ) / T _int is the calculated current service speed. In response to a request by a communication protocol such as an HTTP request, the server transmits the requested data at the maximum speed within the range accommodated by the other party, that is, the wireless communication terminal. Its speed is limited on the path of the wireless service. Therefore, when the server measures the amount of data received through the socket for a predetermined time with respect to the data transmitted at the maximum speed, the service rate provided by the current access point as a radio signal to the terminal is reflected in the measured value . If the terminal transmits a request based on a communication protocol in which the server restricts the content data to a predetermined rate and requests the content of the remote site, for example, as an RTSP / RTP request, the transmission / Requests a test file of several hundreds of kbytes as an HTTP Request to a designated specific server and performs a receiving operation at an arbitrary cycle to detect the time at which the test file is received for each request, May be measured. If the operating system 100a continuously measures the service speed for the currently connected access point, the transmission / reception control unit 112 may request the operating system 100a to use the information.

In the embodiment of the present invention, the transmission / reception control unit 112 may set the service speed of the current access point to a specific execution object (application or process, etc.) being executed in the wireless communication terminal 100, And provides the UI processing unit 111 with the information. In the present embodiment, the specific execution entity performs an operation of measuring the service speed of the connection point described above with respect to the transmission / reception control section 112, and provides information on the measured service speed to the transmission / reception control section 112 do. In addition, in the present embodiment, the specific execution entity may be configured to not only measure the service speed for the connection point and provide speed information, but also store the content data that the other execution entity, for example, May be provided. In the case of having the data relay function, a request by the communication protocol that the media player 110 wants to transmit to the outside via the operating system 100a, for example, an HTTP request, Is transmitted to the specific execution entity by a redirection instruction, and the specific execution entity transmits a response according to the request, that is, content data, by transmitting the request to the destination of the request through the operating system 100a Instead. The content data received in this way is transmitted to the media player 110 that transmitted the request for the first time, thereby performing the data relay function in the wireless communication terminal 100. [ In this case, an internal socket may be used as a data path between the specific execution entity and another execution entity, for example, the media player 110. The internal socket refers to a socket that is the same as the general socket and information structure and usage method used by the operating system 100a to provide communication services with an external entity for an arbitrary execution entity or a destination of the socket Refers to different sockets in that they are all internal execution objects that are executed based on the operating system 100a.

If the service rate can not be determined for the current connection point, for example, when the current time falls within the specified status check cycle, there is no service rate measured for the connection point yet, or the average value of the measurements during the valid time is not secured Reception control unit 112 notifies the UI processing unit 111 of the default service speed previously set for the Wi-Fi network to the UI processing unit 111, The service speed is notified. This default service rate may be one fixed value and may be some value that can be selected according to the condition. In the latter case, different default service rates may be provided, for example, according to a service set identifier (SSID) of several major access points. In addition, different default service rates may be provided depending on the time zone (e.g., morning, afternoon, evening, etc.) and day of the week type (e.g. weekday, weekend, holiday, etc.). In this way, when a plurality of default service speeds are provided, the transmission / reception control unit 112 selects a default service speed corresponding to the current situation (the service identifier of the connected access point or the current day type and the time zone) The UI processing unit 111 is notified. Information related to the current situation is requested and confirmed by the operating system 100a. In the case of information on connected access points, when the Wi-Fi modem 2a physically searches for a Wi-Fi signal band, if a valid signal is detected, identification information of each access point retrieved from the signal, The operating system 100a detects an identifier or a MAC address and a received signal strength indicator (RSSI) of the connection point and provides the received signal strength indicator to the operating system 100a, The control unit 112 informs the transmission / reception control unit 112 of the above-described information.

On the other hand, the media processing unit 113 determines the decoding method based on the encoding information of the data recorded in the header of the content data provided from the transmission / reception control unit 112, and then, according to the determined decoding method Partially or completely decodes the content data. In case of partial decoding, the decoder 8 is also set to the determined decoding method. The partial decoding may be extraction of media packets, for example, block unit, picture unit, or Group of Pictures (GoP) unit. In the case of partial decoding as described above, the decoded media packets are applied to the decoder 8 to request decoding, thereby outputting the video and audio signals of the decoded media packets. The image data completely decoded by the media processing unit 113 is applied to the display driver 4 through the operating system 100a to be output as a video signal. As a result, the user starts listening to the content selected by the user.

3B, the UI processing unit 111 maintains a normal standby mode in which an appropriate menu screen or an operation according to the request is performed when a user requests it, , When the service speed of the connection point measured by the transmission / reception control unit 112 is notified (S321), it is determined whether or not the wireless communication network other than the Wi-Fi network 11b currently used for receiving the content data, The expected data amount to be received by additionally using the service rate 11a is calculated using the notified service speed (S322). In order to calculate the expected data amount, the UI processing unit 111 refers to the metadata of the currently received content created by the transmission / reception control unit 112, and grasps the necessary speed requested by the current content first. Here, the required speed is a value for a data rate obtained by dividing the size of the content file by the play time of the content or a data amount to be decoded per a predetermined time (for example, 1 second) , It is necessary to play at the necessary speed or more to play the content normally. That is, a phenomenon such as break, screen break, or stop does not occur.

The UI processing unit 111 compares the required speed with the required speed each time the measured service speed is notified from the transmission / reception control unit 112 to the current connection point, while the necessary speed for the content is grasped, As a result, if the service speed is higher than the necessary speed, the expected usage amount for the cellular network is determined as 0. If the service speed is lower than the required speed as a result of the comparison, the UI processing unit 111 calculates an expected usage amount (Pred_DSize) for the cellular network 11a according to the following equation [1].

Pred_DSize = (ReqSpd - Ap_SvcSpd) * (Ply_Time - Plyed_Time) Expression [1]

Here, Plyed_Time = Recvd_DSize * Ply_Time / CTot_DSize, and Expression [1] -1

ReqSpd is the rate of content required,

AP_SvcSpd is the measured service rate for the connected access point,

Ply_Time is the total play time of the content,

Plyed_Time is the time at which the play progressed to the content,

Recvd_DSize is the size of data received up to the present time on the content,

CTot_DSize indicates the size of the content data (i.e., the size of the content file).

The expected usage calculated according to Equation [1] is for the remainder of the content at the current point in time. Therefore, in the case of before play (Plyed_Time = 0), the expected usage amount is the amount of data estimated to use the cellular network 11a before the play for the entire content.

The UI processing unit 111 notifies the reception amount (Recvd_DSize) information of the content tracked by the transmission / reception control unit 112 up to the present time from the transmission / reception control unit 112 as described above, Although it is possible to grasp the time (Plyed_Time) at which the play progressed according to Equation [1] -1, the media processing unit 113 may request the media processing unit 113 to grasp the current play time (Plyed_Time). When the playing time (Plyed_Time) is recognized, the expected information amount for the cellular network is calculated by substituting the information (the required speed of the content and the total playing time) and the service speed of the notified connection point into the equation [1].

When the expected usage amount for the cellular network is calculated, the UI processing unit 111 transmits information indicating the expected usage amount to the media processing unit 113 on the display panel 5, as illustrated in FIG. 5, (52) on the upper part of the window (51) representing the image of the image (52) (S323). Of course, the Wi-Fi network 11b is basically used so that a symbol or indicator 501 indicating that data of the content is being received is maintained in a state of connection with the Wi-Fi network 11b It is always displayed at a specific position on the screen. 5, when the user plays the content selected by the user from the current play point to the end and watches the selected content, the user is informed of how much of the cellular network he / It is determined whether the amount of data is expected to be used, and based on the prediction information, it is decided whether to proceed with the content play or to watch in a place where more Wi-Fi network is available.

Since the expected usage amount information calculated as described above and displayed on the screen is a value at a specific point in time, the value changes as the measured service speed changes. Basically, as the time for decoding the content data received by the media processing unit 113 and outputting the content data is elapsed, the value of the content data is set to the service speed 62 of the measured connection point as illustrated in FIG. 6 (61). Of course, if the service speed of the connection point becomes instantaneously larger than the required rate of the content, the expected usage amount for the cellular network becomes zero at that moment. Thus, the user may be less aware of the use of the cellular network because he sees the expected usage for the cellular network, which is gradually decreasing during the play of his or her selected content. In order to prevent such a situation, in an embodiment according to the present invention, the total amount of data to be received through the cellular network 11a after the start of the play of the content is estimated as an estimated usage amount 52 (53). An operation of additionally receiving the content data using the cellular network 11a in addition to the currently connected Wi-Fi network 11b will be described later. The UI processing unit 111 inquires the transmission / reception control unit 112 about the amount of data received using the cellular network, and obtains the information.

In another embodiment according to the present invention, instead of displaying the expected amount of usage calculated by the formula [1] on the screen, the information may be appropriately processed and displayed. For example, the data amount information received up to the present time using the cellular network 11a obtained by inquiring to the transmission / reception control unit 112 may be added to the expected usage amount of the cellular network calculated as described above and displayed have. The amount of data thus calculated is separated from the expected amount of usage (Pred_DSize) calculated by Equation [1], and the term "estimated actual use reflected amount" is used. Since the amount of data actually received through the cellular network 11a is added to the estimated actual usage reflected amount displayed on the screen according to the present embodiment, it has a value that increases substantially in accordance with time, The total amount of data to be received using the cellular network 11a from the beginning is a value expected at a certain time. At the end of play, the amount of data actually received is reflected using the cellular network 11a for the play of the content.

On the other hand, after the transmission / reception control unit 112 notifies the UI processing unit 111 of the measured service speed of the connection point, there is a possibility that there is insufficient data in the play of the content (that is, Possibility of occurrence of a situation) (S312). In an embodiment according to the present invention, a buffering amount that has already been received but has not yet been decoded by the media processing unit 113 (for example, the amount of buffering that has not been read by the media processing unit 113 in the shared memory 42) (I.e., the remaining amount of data - hereinafter referred to as the "amount of untreated data") is a data amount equal to or less than a predetermined time limit (for example, 2 seconds or 3 seconds) It is judged that there is a possibility of data shortage. The conversion between the data amount and the time value is performed by the conversion factor (a = S / T) determined by the data size (S) of the current content and the play time (T). That is, a given time value is multiplied by the conversion coefficient to obtain a corresponding data amount, and a given data amount is divided by the conversion coefficient to obtain a corresponding time value.

In another embodiment according to the present invention, it can be determined that there is a possibility of data shortage if the service speed of the current access point is lower than the required speed of the content and only the current single network, that is, the Wi-Fi network 11b is being used.

If it is determined that there is a possibility of data shortage, the transmission / reception control unit 112 uses a plurality of communication networks. That is, the cellular network 11a is additionally used to receive part of the content data (S313). 7, the transmission / reception control unit 112 stores a predetermined period 701 (for example, 1 second or 2 seconds of data) at the last point 71 of the received content data (For example, a data amount of 5 seconds or 10 seconds) of the content from the point where the content has been skipped, and makes a request based on the communication protocol requesting the content Requesting the request to the operating system 100a while designating the cellular network. At this time, a socket for use of the cellular network is generated, of course, and a request by the communication protocol is requested to the operating system 100a through the socket. Since the interval 702 requested through the cellular network overlaps with the interval specified by the request 710 requesting the corresponding content file to the Wi-Fi network 11b, the point 72 where the overlap starts, And forwards the data through the Wi-Fi network 11b. One way to stop the transmission is to close the socket through which the data is delivered after receiving data up to that point 72 from the operating system 100a. When the socket is closed, the data transmission is stopped by flow control between the operating system 100a and the content server 12 that is transmitting the content data. The transmission / reception control unit 112 creates a request 720 based on a communication protocol requesting data from a point 73 immediately after the requested interval 702 through the cellular network 11a, (11b) to the operating system (100a). If a request based on the communication protocol at this time is requested to be transmitted to the operating system 100a through the newly created socket or if there is an existing socket based on the use of the Wi-Fi network for the same remote location, .

As described above, in response to a request for content data using the cellular network 11a, the data of the requested interval 702 is transmitted to the cellular network 11b separately from the reception of the content data via the Wi-Fi network 11b 11a so that the data reception speed becomes higher than the required speed of the content depending on the use of the plurality of networks, and thus the situation in which the content data becomes insufficient for play is temporarily prevented. The transmission / reception control unit 112 transmits the content data received through the plurality of sockets from the operating system 100a to the media processing unit 113 (in the order of the data interval requested through the socket) To be stored in an appropriate location on the memory that is shared with each other. Thereby, even if the content data is received by using a plurality of networks temporarily, the playback of the content by the media processing unit 113 proceeds smoothly without any trouble or error.

The transmission / reception control unit 112 temporarily performs an operation of supplementing data by accelerating data reception using the cellular network 11a whenever a data shortage is expected during play, Until the user requests interruption (S314).

According to an exemplary embodiment of the present invention, when it is determined that there is a possibility of data shortage in play, the size of the data section 702 that is supplementarily requested through the cellular network 11a And thus adaptively determined. FIG. 8 is a graph illustrating a rule for determining the size of a data interval supplementarily requested using the cellular network. The illustrated rule is merely to illustrate a basic rule in which the size of a data section to be received through the cellular network is determined to be longer than when the probability of data shortage is high. Other numerical values not illustrated in the figures may be used, or other rules may be applied for the present invention. In the rule illustrated in Fig. 8, the possibility upper limit point 801 in which the size of the data interval does not increase any more is set, but the size of the interval may be determined without setting such an upper limit point. The size of the data shortage possibility is determined by the time difference that the time corresponding to the current unprocessed data amount does not reach the above-mentioned time limit. That is, the greater the time difference, the higher the possibility of data shortage. Alternatively, the current service speed of the connection point may be determined by a speed difference that does not meet the required speed of the content.

On the other hand, in the case where the UI processing unit 111 displays the estimated usage amount for the cellular network (together with the actual usage amount for the cellular network) or the actual usage reflected expected amount on the screen, in the embodiment of the present invention, Wi It can also be displayed together with the actual usage for the -Fi network. In the present embodiment, the UI processing unit 111 sets the actual usage amount of the Wi-Fi network 11b at the required time (for example, before the expected usage amount for the cellular network is displayed on the screen) Reception control unit 112 and acquires them. The UI processing unit 111 displays the actual usage amount of the Wi-Fi network 11b on the screen of the wireless communication terminal 100 together with the expected usage amount for the cellular network 11a, Information may be displayed only in a text form as shown in the screen illustrated in FIG. 5, but may be expressed in a graphic form or with text information so that the user can grasp it at a glance. FIG. 9 is an example of information on the usage amount displayed in accordance with the present invention. The usage status bar is displayed based on 15 MBytes assumed for the size of the content currently playing. Network indicators 90a and 90b indicating that the information on the amount of usage indicated in the usage status bar is for a certain network are also displayed.

9, it is assumed that 3012 KBytes is received in the Wi-Fi network 11b and 845 KBytes in the cellular network 11a up to the current time, Based on the service speed measured at the current point in time for the access point, or based on the service speed information obtained for the connected access point (the acquisition of the service speed information for the access point will be described later in detail) The amount of data expected to be received through the network 11a is 2912 KBytes (901). The UI processing unit 111 displays a usage identifier 91 on the usage status bar that allows intuitive determination of how much data is to be used through a certain communication network. The display position of the usage amount identifier 91 is calculated from the starting point 92 indicating the usage amount for the cellular network and the data amount obtained by adding the actual usage amount to the cellular network and the expected usage amount 901 ). The user can intuitively know how much data amount is to be received using the cellular network 11a in order to complete the current content based on the position on the usage status bar indicated by the usage amount identifier 91 . The UI processing unit 111 subtracts the identified usage amounts (3012, 845, 2912 KBytes) from the size of the entire data (assumed 15000 KBytes) obtained from the metadata of the currently selected content (8231 = 15000 -3012 -845-2912) may be displayed on the usage status bar as the amount of data expected to be received through the Wi-Fi network 11b.

As described above, the UI processing unit 111 reflects, in real time, the service speed of the connection point measured while the transmission / reception control unit 112 receives the content data currently being played, and calculates the expected usage amount for the cellular network, The usage indicator 91 will be displayed on the usage status bar while being vibrated in the left and right direction because the actual usage reflected amount is changed dynamically in the case of providing to the user through the usage status bar in the manner as illustrated in FIG. On the other hand, in the embodiment using service rate information acquired for the currently connected access point as described later, the expected usage amount for the cellular network 11a is displayed once using the acquired rate information, and thereafter The usage identifier 91 will be maintained until the content playback is stopped for the first displayed position. In this case, however, only the portion indicating the amount of data actually received through each wireless communication network (each portion hatched in the usage status bar in Fig. 9) will become larger while approaching the center.

In the case of displaying the expected usage amount for the cellular network as in the above-described embodiments, if there is a limitation amount per content set by the user, the UI processing unit 111 can also display the limitation amount information on the screen have. Alternatively, instead of the limited amount per the set content, an estimated remaining amount obtained by subtracting the real use reflected amount as described above from the limited amount may be displayed on the screen. The user can set a limit amount per content in order to prevent excessive use of data when viewing any content through the wireless communication terminal. The set amount of content per unit of content can be set in the operating environment information of the terminal through the UI provided by the wireless communication terminal 100. The operating environment information thus set is transmitted to the operating system 100a through a request And the UI processing unit 111 can confirm this. Alternatively, it may be directly set in the media player 110 through a menu screen provided by the UI processing unit 111. [

On the other hand, the display of the predicted usage amount (or the actual usage reflected amount) for the cellular network as described above is based on the total size of the currently playing content. However, there are cases where the size of the currently playing content is unknown. For example, in the case of live contents, since it is captured and provided in real time, it is usually unknown when the data of the content is ended. That is, the total size of the content is not normally known. Accordingly, in the case of the live content, the UI processing unit 111 can calculate the expected usage amount (or the actual usage reflected amount (for example, ) On the screen. In the following description, even if the actual use reflected amount is not separately written in parentheses but only the expected usage amount is described, unless the related explanation does not meet the actual use reflected amount, The present invention is not limited thereto.

If the content selected by the user is provided by a live streaming method, the transmission / reception control unit 112 requests each file in the order of fragmented files described in the piece list information received in response to the request for the content, And provides the received data of the fragmented file to the media processing unit 113. Since the play time for each piece file is specified in the piece list information and the total size of the piece file in addition to the corresponding data is described in the response when the piece file is requested, the transmission / You can determine the required speed of the fragment file. Therefore, the transmission / reception control unit 112 calculates the average value of the required speeds at each reception of each fragment file while grasping the required speed for each fragment file of the selected live content. Then, the required speed average value thus calculated is provided to the UI processing section 111 at an arbitrary cycle or whenever the necessary speed average value is changed. Then, the UI processing unit 111 transmits the average speed value of the provided live content to the service speed of the connection point measured or provided by the transmission / reception control unit 112 in real time (or, for example, And if the speed of the latter is insufficient, the predicted amount of use for the cellular network 11a is calculated by multiplying the insufficient speed by a predetermined time. Then, the estimated usage amount thus calculated is displayed on the screen. The amount of data using the cellular network 11a from the start of the play of the content to the present can be also displayed on the screen even when the expected usage amount of the cellular network for the live content is displayed on the screen. Alternatively, the actual use reflection estimated amount obtained by adding the expected usage amount for the cellular network 11a for a certain period of time to the data amount using the cellular network 11a until the present time may be displayed on the screen. In addition, several different times are designated for the predetermined time to calculate an expected usage amount (or actual use reflected amount) for each designated time (for example, 1 minute, 5 minutes, and 10 minutes) Respectively.

In an embodiment according to the present invention, the user may set a limited usage amount that is additionally applied when the user is a live content. The setting of the limited usage amount at this time is also set to the time width to which the limited usage amount is applied. Alternatively, it may be set as a limit speed corresponding to a desired limited usage amount for the designated time width. The limitation information, that is, the limited usage amount, the time width, or the restriction speed may be displayed on the screen together with the expected usage amount for the cellular network by the UI processing unit 111. [

In the above-described embodiments, when the media player 110 directly measures the service speed provided by the Wi-Fi network 11b while receiving the remote content selected by the user, When the cellular network 11a is additionally required, the expected usage amount or the like is displayed on the screen of the wireless communication terminal. In other embodiments according to the present invention, by using the service rate information that has been measured for the corresponding access point before the current content data is received, the expected amount of usage of the currently received content for the cellular network 11a And provides it to the user. In the present embodiment, the transmission / reception control unit 112 requests the remote site for arbitrary content selected by the user while being connected to the Wi-Fi network 11b, receives the data and transmits the request to the media processing unit 113 ), The service speed of the connected access point in the above-described manner, that is, the used speed, is measured. Then, the average value of the usage rates measured repeatedly until the end of the play for the content or until the connection with the connection point is released is recorded as the support rate of the connection point together with the identification information of the connection point. FIG. 10A shows an example of an access point property table in which support rates obtained for an arbitrary access point in this manner are collected and configured. In the connection point characteristic table constructed as shown in FIG. 10A, if there is a previously recorded support speed for the connection point at which the currently measured support speed is to be recorded, the support speed is updated and recorded, or the previous support speed and the average value It can be recorded as the support speed of the connection point.

In another embodiment according to the present invention, when constructing the connection point characteristic table, the average service speed for the arbitrary connection points obtained by the present measurement is divided for the current day type and the time zone, and written for the corresponding connection point. 10B shows an example of the characteristic table of the connection point constructed according to the present embodiment. As illustrated in FIG. 10B for the measured service speed, when the connection point characteristic table is constructed, if there is a support speed recorded by measuring the time corresponding to the same connection condition with the same connection point, it is replaced with the newly measured speed, May update the recorded support rate.

In an embodiment according to the present invention, when the support speed obtained by measuring the arbitrary connection point is described in the connection point characteristic table, the date and time at that time may be described together. In the present embodiment, when the support rate described for the currently connected access point is used to calculate the expected usage amount for the cellular network in a manner to be described below, if the predetermined time period has elapsed from the recorded date and time, It may not be used to calculate the expected usage amount. Instead, it uses the default service rate as described above that is applicable for that connection point, or the service rate obtained by measuring for that connection point through reception of the test file as described above.

10A or 10B, in the embodiment according to the present invention in which the support rate information when the base service is connected and the data service is used is collected, the transmission / reception control unit 112 determines whether or not the radio communication terminal 100 When the user selects the content selected by the user in the state of using the Wi-Fi network by connecting to an arbitrary connection point and receives the data from the remote site as described above and starts to deliver the data to the media processing unit 113, Requests the operating system 100a to identify the currently connected access point and confirms the identified identification information in the access point characteristic table configured as shown in FIG. 10A or 10B, which is managed by the operating system 100a. If the same identification information is found in the search, the registered support speed for the identification information is read and the UI processing unit 111 is notified as the service speed of the current access point. In the embodiment according to FIG. 10B, the UI processing unit 111 is notified by reading the support speeds registered in the entry items which are the same with the identification information but which match the current day type and time zone. If the same connection point is not listed in the connection point characteristic table (the embodiment of Fig. 10A), or if the support rate is not registered in the entry corresponding to the current day type and time zone (the embodiment of Fig. 10B) The transmission / reception control unit 112 notifies the UI processing unit 111 of the corresponding default service speed or the service speed measured through acquisition of the test file, as described above. If there is such a notification of the service speed, the UI processing unit 111 calculates the expected usage amount for the cellular network 11a in the manner described above, and the image is represented by the media processing unit 113 It is displayed adjacently to or overlapped with the window.

10A or 10B by measuring and recording the service rate provided when using the data service via any access point, as described above, may be performed by the media player (e. G. (An application or a process, and the like) for performing another unique function (for example, a function of controlling a Wi-Fi network connection of the wireless communication terminal, etc.) other than the specific execution object . ≪ / RTI > In this case, when the transmission / reception control unit 112 requests the content selected by the user at the remote location and starts receiving the response, the transmission / reception control unit 112 transmits identification information of the currently connected access point to the execution object of the unique function or the specific execution object And provides the UI to the UI processing unit 111 in response to the support rate registered for the connection point. As a result, the above-described expected amount of usage calculation for the content selected by the user is performed. The unique execution entity or the specific execution entity always maintains its execution state in the background mode in the wireless communication terminal 100 at all times.

In another embodiment in accordance with the present invention that utilizes the service rate information that was previously measured for that connection point prior to receipt of the content data, the support rate recorded as illustrated in FIG. 10A or 10B Instead of using the media player 110, the transmission / reception control unit 112 transmits an HTTP Request to the predetermined server at the time of connection to the arbitrary connection point or change of connection in the execution state of the media player 110 to receive the test file The service speed provided by the connected access point can be measured in advance. The pre-measured service speed is provided to the UI processing unit 111 when the content selected by the user is played, thereby being used for calculating the expected usage amount of the content with respect to the cellular network as described above.

As described above, in an embodiment that displays the expected usage of the cellular network for the current play requested content, previously measured for that attachment point or using a pre-measured service rate via a test file prior to content reception, The expected usage amount can remain unchanged until the play on the current content is terminated. Of course, also in this embodiment, the amount of data actually received using the cellular network 11a can be displayed on the screen as in the above-described embodiment. In another embodiment according to the present invention, the expected usage amount of the cellular network 11a with respect to the content currently requested to play is displayed using the service rate previously measured for the corresponding connection point or measured in advance through the test file In this case, if a predetermined time, for example, one minute, elapses after the start of the play, if the current content data is being received through the access point of the connected Wi-Fi network, (Or actual use reflection expected amount) for the cellular network reflecting the actual usage can be displayed in real time.

In the above-described embodiment, the speed information obtained by measuring directly at the wireless communication terminal 100 is used for the currently connected connection point. In another embodiment of the present invention, the service rate of the currently connected access point may be provided from an external access point information providing server that provides information on the access point. In this embodiment, the media player 110 (or a specific executing entity that performs other functions) executed in a certain wireless communication terminal receives content data from an arbitrary server through the Wi-Fi network 11b The service speed measured as described above is transmitted to the connection point information providing server together with the identification information of the connection point. When the connection point information providing server receives two or more service speeds for the same connection point, the connection point information providing server updates the received service speed with a later received service speed or records the previously received service speed and average value as a service speed for the corresponding connection point . When the wireless communication terminal 100 connects to the Wi-Fi network 11b or when the connected access point is changed, the transmission / reception control unit 112 of the media player 110 transmits the connection point From the operating system 100a, and obtains the service speed for the corresponding access point while providing the identification information to the access point information providing server. As to the service rate thus obtained, the transmission / reception control unit 112 requests the content selected by the user at a remote location and provides the content to the UI processing unit 111 at the time of receiving the response, Is used to calculate the usage of the cellular network.

Even in the embodiment in which the service speed for the arbitrary access point is obtained from the access point information providing server and used, the present day type and time zone can be applied. To this end, when the access point identification information and the measured service speed are received from an arbitrary wireless communication terminal, the access point information providing server grasps the type and time zone of the day of the week when the access point identification information and the measured service speed are received, When a request for a service speed is made with an access point identification information from an arbitrary wireless communication terminal, the type and time zone of the day of the week when the request is received are identified, and the received connection point identification The information on the support speed registered in the item corresponding to the day type and the time zone is read and provided to the corresponding terminal.

According to the above-described embodiments, in the case of playing the content selected by the user using the service speed measured in real time or the speed information measured in advance for the connection point of the currently connected Wi-Fi network 11b When the expected usage amount for the cellular network 11a is calculated and displayed on the screen of the wireless communication terminal 100, the expected usage amount (or actual use reflection expected amount) The UI processing unit 111 notifies the user of the amount of content (or a limited amount of usage per predetermined time) set in advance by the processing unit 111 or a content set by the user. In the case where the user is notified according to the present embodiment, any one of the following cases may be used.

First, when the service speed of the access point is measured and used in real-time in the non-live content play, when the actual use reflection amount for the cellular network becomes equal to or more than the limit amount per specified content,

Secondly, in the case of playing non-live content, in the case where the speed information of the connection point measured in advance is used but the real-time measured service speed is not used, the estimated usage amount for the cellular network by the speed information is limited to the specified content amount Or more,

Thirdly, in the case of playing live content, when the estimated actual usage reflection amount for the cellular network including the expected usage amount per a predetermined time is equal to or more than the specified amount per content,

Fourth, in the case of playing live content, the expected amount of usage for a certain period of time for the cellular network is more than the amount corresponding to the specified speed limit.

Any case belonging to the cases exemplified above is hereinafter referred to as "exceeding the limit of the anticipated amount ", and the designated limit amount per content and the limit speed are collectively referred to as the" limit limit ".

In an embodiment according to the present invention, the UI processing unit 111 appropriately calls the API provided by the operating system 100a, as shown in the screen illustrated in FIG. 11, And a control window 1100 including guidance information indicating that the status is exceeded and allowing input or selection to adjust the restriction criteria is configured on the screen of the wireless communication terminal 100. [ 11 shows that the amount of data that additionally uses the cellular network 11a while playing the corresponding content up to now is 8,780 KBytes and the service amount provided by the connection point of the Wi-Fi network 11b at present The estimated usage amount for the cellular network 11a is calculated as 1,225 KBytes based on the speed and assumes that the sum (actual use reflected amount) exceeds the limit amount per content of 10,000 KBytes set by the user It is. 11 is an example in the middle of playing the selected content. However, as described above, even if the expected usage amount for the cellular network exceeds the limit criterion before or after the start of the content play, A control window for adjusting the restriction criterion as illustrated in Fig. 11 may be provided on the screen as well.

The user may either raise the restriction criterion through the control window 1100 as illustrated in FIG. 11 or ignore the guidance for exceeding the limit of the expected amount. When the limitation criterion is raised, the UI processing unit 111 is applied to determine whether the limit criterion exceeds the limit of the estimated amount. If the user ignores the guideline for exceeding the estimated amount limit, the user may continue to play the content or may stop playing the content.

In one embodiment according to the present invention, instead of guiding the adjustment of the restriction criterion as described above, the quality change of the content may be guided. This embodiment can be applied when the content selected by the user is provided at a different quality or bit rate. For example, when the selected content is live content, when the content is requested, the list information for each media stream having a different quality or bit rate is stored in the media index information 1200 created in the manner illustrated in FIG. Lt; / RTI > is received. When the media index information 1200 of a list of media streams of different quality is received, the transmission / reception control unit 112 transmits the media index information 1200 to the UI processing unit 111, For each media stream described in the index information 1200, items to be selected by the user are displayed on the screen together with the usage bandwidth 1201 indicating the quality, and when one of the media stream items is selected, To the transmission / reception control unit 112, information capable of requesting the media stream of the selected item. Then, the UI processing unit 111 marks the media index information 1200 for the selected media stream. The transmission / reception control unit 112 generates a request based on a communication protocol, for example, an HTTP request, from information capable of requesting the selected media stream received from the UI processing unit 111, To the Wi-Fi network 11b. Thus, the slice list information for the corresponding media stream is received, the sequential transmission request for each slice file of the transmission / reception control unit 112 based on the slice list information proceeds, data of the media stream of the selected quality is received And is provided to the media processing unit 113.

While the media stream of the selected quality as described above is being played by the media processing unit 113 (or even after the date has been received but the play has just started or played) , The UI processing unit 111 first confirms whether a media stream of a lower quality than the current quality media stream is being provided for the selected content. This is done based on the previously stored media index information 1200. The UI processing unit 111 searches the stored media index information 1200 to see if there is a media stream of a lower quality or bit rate than the marked media stream 1202 and if there is no such media stream, A confirmation window is displayed on the screen of the wireless communication terminal 100 to inquire whether to continue or stop playing the current media stream. If there is a media stream of a quality lower than the current quality, as illustrated in FIG. 13, a list of media streams of a current quality or lower and a control for selection Window 1300 is formed on the screen. The control window 1300 illustrated in FIG. 13 is based on the assumption that the quality selected by the user for the selected content is 50,000 bps, among the media streams in FIG. 12. In an embodiment of the present invention, when a list of lower quality media streams is presented to the control window 1300, ratio information indicating how much data usage is reduced for each media stream in comparison with the current media stream (1301) may be presented together. Of course, this ratio information is calculated on the basis of information on the usage bandwidth 1201 of each media stream described in the media index information 1200 that has been previously stored.

13, when a media stream is selected by the user in the control window 1300, the UI processing unit 111 transmits information for requesting the selected media stream to the transmission / reception control unit 112 So that the content of the corresponding quality is received from the remote place. In this process, as described above, the slice list information for the media stream of the selected quality is received first, and the quality of the slice list information is reduced according to the request of the sequential slice file of the transmission / reception control unit 112 based on the slice list information degraded content data is received and provided to the media processing unit 113. [ Of course, by receiving data with such reduced quality, the average value of the necessary speeds calculated by the transmission / reception control unit 112 in real time becomes small. The average value of the reduced required speed is provided to the UI processing unit 111 so that the condition exceeding the limit of the estimated amount is released under the condition that the service speed of the current connection point is the same. On the other hand, even when the quality of the content is lowered according to the user's request, the UI processing unit 111 does not initialize the amount of data using the cellular network 11a upon reception of the media stream before the quality change, The amount of data when the cellular network 11a is used to receive the data of the newly selected media stream is added to the usage amount. That is, even if the quality of the media stream is changed, the actual usage before the change of the media stream is reflected in the calculation of the actual usage reflected amount.

In the above-described embodiment, it has been described that the event exceeding the limit amount is processed on the basis of the limit amount per content set by the user or arbitrarily set by the user. In another embodiment according to the present invention, other limits may be set and used. As described above, the basic data amount that can be used without additional charge is allocated to the data service using the cellular network 11a, in the mobile communication plan provided to the mobile communication service provider by the mobile communication service provider. The individuals using the mobile communication pay attention to use the cellular network 11a within a range not exceeding the basic data amount allocated according to the respective charge plan. Such basic data amount can act as a limitation criterion have. In the embodiment of the present invention in which the amount of basic data acts as a limit criterion, before the UI processing unit 111 determines whether or not the limit criterion is exceeded, the wireless communication terminal 100 transmits the cellular network 11a ) Is first obtained. Information on the amount of cellular network usage within the charge period can be received from the server by providing terminal identification information (e.g., subscriber telephone number) to the subscriber information providing server at the pre-designated address. When the current usage amount in the charge period is grasped, the UI processing unit 111 adds the identified usage amount to the estimated usage amount (or actual use reflected amount) calculated based on the service speed of the connection point with respect to the selected content, Is compared with the set limit criterion (i.e., the basic data amount). In this comparison, when the limit is exceeded, the UI processing unit 111 presents a control window for lowering the quality of the current content, as described with reference to the example of FIG. 13, To be performed. In an embodiment according to the present invention, instead of the basic data amount, a data amount corresponding to a certain rate (for example, 80%, 90%, or the like) of the basic data amount may be applied as the limit criterion.

In the embodiments described so far, the expected usage amount (or actual usage reflecting expected amount) for the cellular network is maintained while the content selected by the user is being played. In other embodiments according to the present invention, it is also possible to display the anticipated amount of usage for the cellular network (or actual use reflected anticipation) only in certain cases. For example, in a state where play is being performed on the content selected by the user, information on the estimated usage amount or the like is not displayed on the screen, and when there is a display request by the user, Information on the estimated usage amount and the like is displayed on the screen. Of course, in the latter case, it can be displayed together with the output of the control window for changing the restriction criterion or changing the content quality.

In another embodiment in accordance with the present invention, an expected amount of usage for the cellular network may be provided to the user before play on the content begins. In the present embodiment, since the expected usage amount of the cellular network for the content is displayed before the selection for the play, the expected usage amount to be displayed reflects the service speed of the connection point of the Wi-Fi network that measures while receiving the data of the content And is usage amount information calculated based on the speed information acquired for the connected connection point. In the present embodiment, when the media player 110 is activated in the radio communication terminal 100, the transmission / reception control unit 112 creates a request based on the communication protocol using the pre-designated address information, (Preferably, the Wi-Fi network 11b) of the currently connected wireless communication networks, and when a response to the request is received from the corresponding remote server, the UI processing unit 111). This response may be list information about the content that the remote server (or other associated servers) can provide. Then, the UI processing unit 111 analyzes the response according to the predetermined information format, and displays a content list for user selection on the screen of the wireless communication terminal 100 as shown in FIG. 14 . Of course, the content list as illustrated in FIG. 14 may be obtained after a request to the outside and a response therefrom in response to a selection process of a number of content types.

When displaying the content list on the screen based on the received content list information, the UI processing unit 111 transmits information on the service speed of the connection point of the Wi-Fi network 11b in the currently connected state to the above- And the expected usage amount for the cellular network for each content on the list displayed on the screen is calculated as described above and displayed as illustrated in FIG. 14 (1401). Of course, if the acquired service rate information is higher than the highest required rate of the content in the list displayed on the screen, the expected usage for the cellular network will be all zeros. In an embodiment according to the present invention, when the expected usage amount for each content is displayed as described above, if the expected usage amount exceeds the predetermined limitation criterion (a content limit per content or a predetermined time) And may be displayed on the screen together with information on the restriction criterion (1402).

When the file size and the play time for each content are described in the list information about the contents received from the remote server, the information is used for calculating the expected usage amount, and if there is no such information, The UI processing unit 111 instructs the transmission / reception control unit 112 to acquire and transmit only a part of the head data while providing information capable of requesting each content. In accordance with this instruction, only a part of head data for each content Reception control unit 112, the UI processing unit 111 determines the file size and the play time of the corresponding content from the information included in the respective responses. When only the necessary speed is obtained for the content, as described for the live content, the expected usage amount for a predetermined predetermined time can be calculated and displayed.

The act of indicating the expected amount of usage for the cellular network for each content included in the received content list need not necessarily be performed by an executing entity having the ability to play the content, for example, the media player 110 , An execution entity having a function of transmitting a request by a communication protocol according to a request of a user to a remote location, receiving a response to the request, and displaying a content list on the screen of the wireless communication terminal , A browser, an integrated viewer application for searching contents provided by various content servers, etc.), the above-described function of displaying the expected usage amount for the cellular network performed by the UI processing unit 111 is implemented . In particular, when a user presents a list of the contents provided by various content servers and the user selects one of the listed contents, an execution entity (hereinafter referred to as a "play execution entity " When the function for displaying the expected usage amount for the cellular network as described above is implemented in the execution entity (hereinafter referred to as "integrated execution entity") that is activated in the wireless communication terminal 100, , When the retrieved contents are listed along with the expected usage amount of the cellular network as illustrated in FIG. 14, the restriction criteria are applied to each of the play execution objects capable of playing the content, can do. For example, when the contents to be searched by the integrated execution entity and displayed on the screen are those that can be played by three different play execution entities, the integrated execution entity may include content to be played by the first play execution entity A second limitation criterion for the content by the second play execution entity and a third restriction criterion for the content by the third play execution entity, The third limitation criterion may or may not all have the same value), it is checked whether the expected usage amount for the cellular network calculated for each content exceeds the corresponding limit criterion, And outputs it on the screen. Of course, the restriction criteria for each type of play execution entity may be set in advance by the integrated execution entity, or may be set to an arbitrary value for each play execution entity in the operation environment information of the integrated execution entity by the user.

In one embodiment of the present invention, when one content is selected from the list of contents displayed on the screen of the media player 110, or when another executing entity (for example, a browser or the like) The media player 110 is requested by the operating system 100a in accordance with the installation information associated with the mime type recorded in the response to the request, When the content information selected by the user is received, the media player 110 stores the necessary information (the size of the content file and the play time, or the necessary speed in the case of live content, etc.) The expected usage amount for the cellular network is calculated based on the service speed information of the connection point of the currently connected Wi-Fi network 11b, If the expected usage amount is 0 or less than or equal to the specified default allowable amount (for example, 1 MBytes), the operation of acquiring and playing the data of the selected content is immediately started. Otherwise, the expected usage amount is displayed to the user And present a confirmation window asking whether or not the content is to be played on the screen of the wireless communication terminal 100. In the present embodiment, only the necessary information on the selected content is acquired first by the transmission / reception control unit 112 and transferred to the UI processing unit 111. The UI processing unit 111 transmits the necessary information to the currently connected access point The estimated usage amount for the cellular network 11a is calculated from the service rate information obtained for the cellular network 11a. If the calculated estimated usage amount is not 0 or is larger than the specified default allowed amount, Depending on whether it is approved or not. If it is determined to play the content, the UI processing unit 111 requests the transmission / reception control unit 112 to start receiving data for the previously selected content. Then, the transmission / reception control unit 112 transmits a request by the communication protocol requesting the content through the connection point of the Wi-Fi network 11b in the connection state, and transmits the data of the content to the Wi- (11b) and provides the received content to the media processing unit (113) so that the content is played.

After the play on the content is started, the media player 110 measures the service speed for the current access point in real time, as in the above-described embodiments, while the cellular network 11a, based on the measured speed, (Or actual use reflection estimated amount) for the user to be displayed on the screen in the manner as illustrated in FIG. 5 or 9.

Based on the service rate information acquired for the currently connected access point or based on the service rate obtained by measuring the access point through reception of the test file, an expected usage amount of the selected content for the cellular network is displayed on the screen In the example, the displayed estimated usage amount can be updated and displayed. When there is an actual usage amount for the cellular network 11a, it may be displayed together with the actual usage amount or may be displayed as the actual use reflection expected amount. The expected usage amount can be updated periodically or when the change in signal characteristics (e.g., signal strength, or data reception rate) of the connected access point is large, and the Wi- Or when the connection with the connection point of the connection point is released or changed. According to the present embodiment, when updating the indicated expected usage amount or the like, the transmission / reception control unit 112 receives information on the service speed of the corresponding connection point at the current point in time from the connection point information providing server described above, 111 or transmits a test file to the UI processing unit 111 by requesting the test file again and measuring the received service speed to the UI processing unit 111. The UI processing unit 111 then transmits the service speed to the UI processing unit 111 using the received service speed, The estimated usage amount is calculated and the information displayed on the screen is updated. In particular, when the connection to the connection point is released, the transmission / reception control unit 112 transmits the service speed of the connection point to the UI processing unit 111 as 0, and accordingly, the UI processing unit 111 stores all The expected usage amount is calculated on the premise that the cellular network 11a is used for reception. When the connection point is changed to another connection point, the service speed information obtained by measuring the service speed information received from the connection point information providing server to the changed connection point or through the reception of the test file for the changed connection point is re-calculated . In addition, in the present embodiment, the displayed estimated usage amount is updated even when the quality of the content is changed during the play of the content. In this case, it is also possible to update the anticipated amount of use or the like using the already obtained information without acquiring the service speed information for the connection point again.

Embodiments according to the present invention as described so far are to display the amount of data (or actual use reflection expectation amount) expected to be received using the cellular network for each content of the selected content or the listed contents. In another embodiment according to the present invention, when the above-described limitation criterion is set, the UI processing section 111 determines whether or not the estimated remaining amount (or actual use reflected amount) obtained by subtracting the expected usage amount May be displayed on the screen of the radio communication terminal 100 instead of the expected usage amount (or actual use reflection expected amount) described above. Instead of displaying the value of the predicted remaining amount, the time obtained by dividing the predicted remaining amount by the conversion coefficient determined as described above for the content, that is, the remaining time, may be displayed.

Various methods applied to the method of displaying the expected usage amount information in the data reception of the remote content, which are described in detail in the above-described embodiments, may be appropriately selected and combined together as long as they are incompatible with each other.

As a wireless communication network that can be used by the wireless communication terminal 100, a high-speed wireless LAN that is provided with wireless services locally as very narrow service areas as compared with each cell of a cellular network, in addition to a mobile communication network called a cellular network, The principles and concepts of the present invention will be described in detail with reference to the Wi-Fi network. However, the principle and concept of the present invention is that if there is another type of non-cellular wireless communication network that is relatively inexpensive to use a data service outside of a Wi-Fi network compared to a cellular network, The service rate of the access point providing the access can be applied to calculate the expected usage amount for the cellular network and the like. Further, even in the case of a wireless communication network using the same cellular system, in the case of operating in a separate communication network in which the modulation / demodulation of signals, the transmission / reception band, or the channel coding are different from each other and are separated from each other, The service speed of the access point that makes it possible to access the communication network may be applied to the calculation of the expected usage amount of another cellular wireless communication network with respect to the arbitrary content in the same manner as described above.
