In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may be changed according to intention or custom of a user, an operator, or the like. Therefore, the definition should be made based on the technical idea described throughout this specification.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a block diagram of a data service providing system suitable for applying a data service control apparatus according to the present invention, which includes a user terminal group 110, a network 120, and a plurality of user terminals 110/1 110 / n. The conversion service server 130, the network 140, the network load management node 150, and the web server 160 may be included.

Referring to FIG. 1, each of the user terminals 110/1110 / n in the user terminal group 110 is a wireless portable terminal used by a user who wants to receive an adaptive data service based on an access network provided according to the present invention. (For example, a mobile phone, a smart phone, a smart pad, a notepad, a tablet PC, etc.), each of these user terminals 110/1-110 / n is connected to a connection path via the network 120 according to a user's operation. By connecting to the conversion service server 130 through, the conversion service server 130 can be provided with an access network-based adaptive data service provided to each user terminal according to the present invention.

The network 120 may include, for example, a second generation (2G) wireless network (eg, a CDMA mobile communication system, etc.), a third generation (3G) wireless network (eg, a WCDMA mobile communication system, etc.), and a fourth generation (4G) wireless network. (Eg, LTE mobile communication system, etc.), a wireless communication network including any one of future generation wireless networks or a combination of at least two or more wireless networks and a wired communication network including a wired Internet. That is, the network 120 may provide a wireless communication path between each user terminal, and may provide a wired communication path with the conversion service server 130.

Next, the conversion service server 130 converts the data of the service response received from the web server according to the conversion level (compression level or transmission quality level) determined based on the connection network load information provided from the network load management node, and the user terminal. Means a data service control device of the present invention that services to the user, for this purpose, the conversion service server 130 may include the components as shown in Figure 2, the network-based adaptation to users in accordance with the present invention Details of providing a data service will be described later in detail with reference to FIGS. 2 to 4.

Here, the access network load information may be, for example, load information of a base station or an eNodeB where a user terminal is located, may include load information of a forwarding node such as a gateway (GW), and may also include radio wave strength of the user terminal. It may include time zone information on whether or not to apply the transformation, for example, information about a preset time zone for applying a transformation and information about time zones for which no transformation is applied.

Here, the conversion level for the data of the service response determined according to the access network load information may be set to different compression levels (compression ratio) according to the type of data (eg, video, image, text, etc.). For example, the video may be set to a relatively high compression rate (relatively high bitrate), and the image and text may be set to a relatively low compression rate (relatively low bitrate).

In addition, the conversion level is set to be time-selective, that is, in a time zone in which communication traffic occurs relatively frequently (a preset conversion time zone), the transformation is applied to data of a service response received (obtained) from the corresponding web server. In a time zone (e.g., a late night time zone, a dawn time zone, etc.) where communication traffic is less likely to occur (eg, a non-conversion time zone set in advance), a transformation may not be applied to data of a service response received (obtained) from a corresponding web server. Can be. These conversion application time zones and non-application time zones may be set (determined) according to the service policy at the network load management node or by requests from each site.

The conversion level (compression level) may be dynamically determined according to load information of the access network. For example, 1 Mbps may be transmitted to the user terminal is compressed to 800Kbps, 600Kbps, 400Kbps, etc. according to the load of the access network.

In addition, when the access network load information includes the radio wave strength of the user terminal, the conversion service server 130 changes the conversion level so that a relatively low bit rate occurs when the radio wave strength of the user terminal is less than or equal to a preset reference strength. When the radio wave strength of the corresponding user terminal is greater than or equal to the preset reference intensity, the conversion level may be changed to generate a relatively high bit rate. This is because the user terminal may not receive the data properly even if the data is transmitted at a high bit rate when the radio wave strength is weak. This is to suppress unnecessary data traffic even though the reception possibility is low.

For example, assuming that 1 Mbps of data is compressed at a bit rate of 800 Kbps according to a conversion level determined based on access network load information. Compression is transmitted at a low bit rate.

In addition, the network 140 refers to a wired communication network including, for example, a wired Internet, such as the network 140 between the conversion service server 130 and the network load management node 150 and the conversion service server 130. And a wired communication path between the web server 160.

In addition, the network load management node 150 may detect and manage a load state of a network (mobile communication network) in real time, or provide a function such as managing and changing a network operation policy. For example, it may mean changing the application level of the conversion level itself or changing the range of the conversion level according to the load state of the network. The information such as the access network load information, the network operation policy, and the policy change managed here may be transmitted to the conversion service server 130 through the network 140 in order to realize the present invention.

Finally, web server 160 is, for example, YouTube. It refers to a server operated by a site such as Naver, Daum, Nate, Google, etc., and when a service request (eg, a video, image, text, flash animation, etc.) is requested from the conversion service server 130, The service response data corresponding to the service request may be retrieved from the DB and transmitted to the conversion service server 130 through the network 140.

2 is a block diagram of an adaptive data service control apparatus based on an access network according to the present invention, wherein the service response data acquisition unit 202, the load state acquisition unit 204, the conversion level determination unit 206, and data conversion execution are performed. The unit 208 and the data storage unit 210 may be included.

Referring to FIG. 2, the service response data acquisition unit 202 responds to a web service request when the web service request is received from the user terminal (for example, 110/1) together with identifier information of a related site (web server) through the network 120. Sends a request for a service response by transmitting to the web server 160, and provides a function such as obtaining data (eg, video, image, text, etc.) of the service response transmitted from the web server 160 in response to the request. can do.

Next, the load state obtaining unit 204 requests access network load information to the network load management node 150 via the network 140 when the web service request is received from the user terminal 110/1 (related web server). Request to include the site separator information), and in response to the request, obtain the access network load information provided from the network load management node 150 through the network 140, and store or update the data in the data storage unit 210. Can provide functionality.

In this case, the access network load information may include, for example, load information of a base station or eNodeB where a user terminal is located, load information of a forwarding node such as a gateway (GW), propagation strength of the user terminal, and time zone information on whether the transformation is applied (preset transformation). Applicable time zone information and preset non-conversion time zone information).

In addition, the load state acquisition unit 204, according to another embodiment of the present invention, regardless of the service request from the user terminal (110/1), the access network provided from the network load management node 150 at a predetermined predetermined period A function of acquiring load information and storing or updating the data in the data storage 210 may be provided.

Meanwhile, the conversion level determining unit 206 analyzes the access network load information obtained and stored in the data storage unit 210, and the data of the service response (eg, received) obtained from the web server 160 according to the analysis result. Functions such as determining whether to apply (execute) a transform to a video, an image, text, etc., or determine the level of the transform.

That is, the conversion level determiner 206 may include load information of a base station or eNodeB in which a user terminal is located, load information of a forwarding node such as a gateway (GW), propagation strength of the user terminal, and time zone information on whether to apply a transform (preliminary description). By taking into consideration the set conversion application time zone information and the preset conversion non-application time zone information), etc., it may be decided to compress the data of 1 Mbps into a relatively low bit rate such as 800 Kbps, 600 Kbps, 400 Kbps, and the like.

In addition, the conversion level determiner 206 checks the current time when the service response is obtained (received) from the web server 160 when the data conversion is set to be selectively applied. The application of data conversion may be determined when the set conversion time zone is applied. Alternatively, the application of data conversion may be determined when the current time is a preset non-application time zone (eg, a late night time zone or a dawn time zone).

Further, the conversion level determining unit 206 checks the radio wave strength of the user terminal 110/1 when the access network load information includes the radio wave strength of the user terminal, and relatively when the radio wave strength is less than or equal to the preset reference intensity. The conversion level may be changed to generate a low bit rate, and the conversion level may be changed to generate a relatively high bit rate when the radio wave strength of the corresponding user terminal 110/1 is greater than or equal to a preset reference strength.

Meanwhile, the conversion determining unit 206 sets the conversion level relatively low when the network load is low based on the access network load information (ie, when the access network load information is less than or equal to the preset reference load) and when the network load is high (ie For example, when the network load information is greater than or equal to a predetermined reference load, the conversion level can be set relatively high.

In addition, the conversion determining unit 206 does not apply data conversion (compression) to the traffic of all users (subscribers), and a relatively low priority such as some users, for example, heavy users. May decide to compress only their traffic (apply transform selection).

In addition, the conversion determination unit 206 may set the data conversion to be adaptively applied for each data type according to the load fluctuation state of the access network. For example, if a network load is detected, the video traffic is first compressed by 10%, and when the network load is maintained and increased, the video traffic is compressed by 20% and the image traffic is compressed by 10%. You can decide to apply 30% compression, 20% compression of image traffic, and 50% compression for all traffic if the network load exceeds a certain set threshold.

Next, when the data conversion application instruction is provided from the conversion level determining section 206, the data conversion executing section 208 sends the data of the service response obtained from the web server 160 to the determined conversion level (compression level or transmission quality). Level), and transmits the converted data to the corresponding user terminal 110/1, and stores the conversion result value of the data in the data storage 210. FIG. .

Here, the transformation on the data of the service response may be performed by decompressing the data of the service response through, for example, a decoding process, and recompressing the data of the service response decompressed through the encoding process at a relatively high preset compression rate. Can be executed.

Next, a series of processes for adaptively providing a data service to a user terminal based on access network load information through the data service control apparatus of the present invention having the above-described configuration will be described in detail.

3 is a flowchart illustrating a main process of providing an adaptive data service based on an access network according to an embodiment of the present invention.

Referring to FIG. 3, when any user terminal (eg, 110/1) accesses the conversion service server 130 through the network 120 and requests a service for the web server 160 (step 302), The load state acquisition unit 204 in the conversion service server 130 requests access network load information by accessing the network load management node 150 through the network 140 (step 304).

In response, the network load management node 150 retrieves the relevant access network load information from the information management DB (not shown) and transmits it to the conversion service server 130 via the network 140 (response request) (step 306). The load information of the access network may optionally include, for example, load information of a base station or eNodeB where a user terminal is located, load information of a forwarding node such as a gateway (GW), propagation strength of the user terminal, time zone information on whether to apply a transform, and the like. can do.

Next, the translation level determining unit 206 in the translation service server 130 analyzes the obtained access network load information, and the data of the service response to be received (obtained) from the web server 160 according to the analysis result (eg, For a video, an image, text, etc., it is determined whether to apply (execute) the transformation and its transformation level (step 308).

In this case, when the data conversion is set to be selectively applied to the time, the conversion level determining unit 206 checks the current time when the service response is obtained (received) from the web server 160, and the current time is preset. The application of the data transformation is determined in the time zone of the transformation application, and in contrast, the non-application of data transformation will be determined when the current time is a preset non-application time zone (eg, a late night time zone, a dawn time zone, etc.).

In addition, when the access network load information includes the radio wave strength of the user terminal, the conversion level determining unit 206 checks the radio wave strength of the user terminal 110/1 and is relatively low when the radio wave strength is less than or equal to the preset reference intensity. When the propagation strength of the corresponding user terminal 110/1 is greater than or equal to the preset reference strength, it is determined to change the conversion level so that a relatively high bitrate is generated.

Then, the service response data acquisition unit 202 in the conversion service server 130 requests a service response by accessing the web server 160 through the network 140 (step 310), and responds to the request in response to the web. Obtain data (eg, video, image, text, etc.) of the service response delivered from server 160 (step 312).

Next, when the conversion level determining unit 206 determines the data conversion according to the analysis result of the access network load information, the data conversion execution unit 208 converts the data of the service response obtained from the web server 160 (data). Application of the conversion) (step 314), and transmits the converted data through the network 120 to the corresponding user terminal 110/1 (step 316). In this case, the conversion result value of the data may be stored in the data storage unit 210.

That is, the data conversion execution unit 208 decompresses the data of the service response through the decoding process, and then recompresses the data of the service response decompressed through the encoding process at a relatively high preset compression rate. You can run (apply) the transformation.

4 is a flowchart illustrating a main process of providing an adaptive data service based on an access network according to another embodiment of the present invention.

Referring to FIG. 4, the load state acquisition unit 204 in the conversion service server 130 receives (collects) the network load information and policy change request from the network load management node 150 through the network 140 at a predetermined period. (Step 402).

In response, the translation level determination unit 206 generates a policy change response for the network load information and the policy change request when it receives the request and changes the network load management node 150 through the network 140 (step 404). 3, the same process as in FIG. 3 described above is performed to determine whether to apply a transform to the data of the service response and its transform level (step 406), and whether to apply the transform and its level is determined by the network load. Each time connection network load information is received (obtained) from the management node 150, it is dynamically determined or changed and stored (or updated stored) in the data storage unit 210.

Next, when the service response data acquisition unit 202 receives a service request from any user terminal (eg, 110/1) (step 408), the service response data acquisition unit 202 accesses the corresponding web server 160 through the network 140 to perform a service. Request a response (step 410), and obtain data (e.g., video, image, text, etc.) of the service response delivered from the web server 160 in response to the request (step 412).

Thereafter, the data conversion execution unit 208 retrieves the conversion-related information (whether or not to apply the conversion, the conversion level, etc.) from the data storage unit 210, and analyzes the retrieved conversion-related information to apply the conversion. In operation 414, data of the service response obtained from the web server 160 is converted (data compression is applied), and the converted data is transmitted to the corresponding user terminal 110/1 through the network 120 (step 416). ). In this case, the conversion result value of the data may be stored in the data storage unit 210.

For example, the data conversion execution unit 208 decompresses the data of the service response through the decoding process, and then recompresses the data of the service response decompressed through the encoding process at a relatively high preset compression rate. You can run the transformation.
