However, hereinafter, for convenience of description, one core cloud node 200 and one edge cloud node 100 will be described.

The core cloud node 200 is located in the core network 1 and provides a cloud service (or cloud computing) that realizes a data service based on virtualized information technology (IT) resources.

Accordingly, the user, that is, the terminal 10, can use a data service based on a cloud service provided using IT resources such as functions (processes), storage spaces, etc. of various calculation processing such as data classification, calculation, processing, and analysis. have.

Accordingly, the core cloud node 200 performs data calculation processing according to a specific application (hereinafter referred to as an app 15) executed in the terminal 10 based on resources allocated to a user of the terminal 10 as a cloud service target. To provide a cloud service.

Specifically, the core cloud node 200 may provide a cloud service by interworking with the app 15 running on the terminal 10 for the terminal 10 by the user registered in the cloud service provided by the user. have.

That is, the core cloud node 200 is a resource allocated to a corresponding user inside the data generated in connection with the data service provided by the app 15 in conjunction with the app 15 running on the terminal 10 Based on the calculation processing, by providing the data calculation processing result to the app 15 of the terminal 10, it is possible to provide a user context (User Context) based cloud service.

At this time, the data generated in connection with the data service provided by the app 15 is the data generated by the app 15 running on the terminal 10, specifically, the terminal 10 (eg, request data, response data, reporting Data, etc.) and data generated from a separate sensing device (not shown) built for the corresponding data service (eg, collected data, report data, etc.).

The edge cloud node 100 also provides a cloud service (or cloud computing) that realizes a data service based on virtualized information technology (IT) resources.

However, the edge cloud node 100 is a method of selectively performing a specific function (some data calculation processing) of the cloud service at a position closer to the terminal 10 than the core cloud node 200, the core cloud node 200 ) And cloud services.

Specifically, the edge cloud node 100, when the terminal 10 is connected, allocates application execution resources for the app 15 running on the terminal 10, and based on the application execution resources, the app 15 By selectively performing some data calculation processing among the data calculation processing according to, the cloud service may be distributed with the core cloud node 200.

The edge cloud node 100, based on the storage node located at the base station 20 terminal that the terminal 10 accesses for connection with the core network 1, the core cloud node 200 and the cloud service It is preferred to provide dispersion.

More specifically, for example, the edge cloud node 100 may include a mobile edge computing node located at the base station 20 end.

The mobile edge computing node (hereinafter referred to as a MEC node) is a server-type node provided in the base station to store large amounts of data that are frequently utilized by users or require fast transmission and to be immediately transmitted upon request.

Accordingly, the MEC node implements storage for storing large amounts of data that are frequently utilized by users or require fast transmission.

Thus, in the present invention, the edge cloud node 100, in the case of a separate node from the MEC node, provides a core cloud 200 and a cloud service based on the storage of the storage node located at the base station 20, that is, the MEC node. Distributed can be provided.

In this case, the edge cloud node 100 is also preferably located at the base station 20 end.

Alternatively, in the present invention, when the edge cloud node 100 is implemented including a MEC node, the core cloud node 200 and the cloud are based on the storage node located at the base station 20 end, that is, the storage they contain. The service can also be distributed.

In this case, the edge cloud node 100 will be located at the base station 20 end.

Alternatively, in the present invention, the edge cloud node 100 may include a separate storage node or interwork with it, separately from the MEC node, and the core cloud node 200 and the cloud service based on the storage node. It can also be distributed.

From a cloud service point of view, a section in which data generated from an app 15 running on the terminal 10 or a sensing device (not shown) enters a network to be delivered to a subject providing a cloud service (for example, data collection) A section is a section from the terminal 10 or a sensing device (not shown) to the base station 10, and a section for transmitting and calculating data according to a procedure required for the data, such as data entered into the network in this way (eg, section) Data analysis section) may be referred to as a section from the base station 10 to a subject providing a cloud service.

As can be seen in Figure 1, in the present invention, by implementing the edge cloud node 100 to provide a distributed cloud service provided by the core cloud node 200 to the base station 20, the cloud service in the data collection section (cloud Computing).

Hereinafter, a specific configuration of an edge cloud node (device) according to a preferred embodiment of the present invention will be described with reference to FIG. 2.

First, when the edge cloud node 100 of the present invention is described, the edge cloud node 100 includes a terminal interworking unit 110 interworking with a connected terminal 10 and a terminal 10 when the terminal 10 is connected. ), the resource allocation unit 120 for allocating application execution resources for a specific application, that is, the app 15, and data generated in connection with the app 15, the app 15 in the core network 1 stage Selects data related to a specific function of a cloud service provided for, and performs filtering processing on the selected data based on the assigned application execution resource and a filtering unit 130 that delivers other data to the core network 1 By doing so, it includes an application execution unit 140A for providing the cloud service in a distributed manner.

Hereinafter, for convenience of description, reference will be made to reference numerals shown in FIG. 1.

The terminal interworking unit 110 is a function unit interworking with the terminal 10 to be connected.

That is, the terminal interworking unit 110 may check the terminal 10 connected through a predetermined authentication procedure, or may check the unspecified terminal 10 connected without the authentication procedure.

At this time, the method in which the terminal 10 is connected to the edge cloud node 100 and more specifically, the terminal interlocking unit 110 is searched and connected by the edge cloud node search function mounted on the terminal 10 side. Can be realized.

Here, the search function may be a search function developed for the present invention, but may also be a search function provided by a wireless communication (eg, WiFi, etc.) that is used in the past, and is not limited to a separate search function.

Accordingly, the terminal linkage unit 110 receives data (eg, request data, response data, report data, etc.) from the terminal 10 to which connection is confirmed, and transmits data to the terminal 10 (eg, data calculation processing result_App Streaming), it is possible to interwork with the terminal 10.

The resource allocation unit 120 allocates an application execution resource for the app 15 running on the terminal 10 when the terminal 10 is connected.

That is, the resource allocation unit 120, when the connection to the terminal 10 in the terminal interlocking unit 110 is confirmed, the edge cloud node 100 in the computing resource for processing data processing, the terminal 10 Application execution resources for the app 15 running in the can be immediately assigned.

In addition, the resource allocation unit 120, if the terminal 10 connection termination is confirmed in the terminal interlocking unit 110, previously retrieves the application execution resources allocated for the app 15 running on the terminal 10 can do.

The filtering unit 130, among data generated in connection with the app 15 executed in the terminal 10, the data related to a specific function of the cloud service provided for the app 15 in the core network (1) stage Select and transfer other data to the core network (1).

At this time, the data generated in connection with the app 15 means data generated in connection with the data service provided by the app 15 as described above.

That is, the data generated in relation to the app 15 includes data generated in the terminal 10, specifically, the app 15 in the terminal 10 (eg, request data, response data, report data, etc.), and corresponding data. It includes data (eg, collected data, report data, etc.) generated from a separate sensing device (not shown) built for service.

That is, the filtering unit 130, among data generated in connection with the app 15 running on the terminal 10, the core cloud node 200 located in the core network (1) and the cloud service to provide distributed Only data related to the function is filtered (optional), and other data is transmitted to the core network 1.

For example, when the current data generated/received in connection with the app 15 executed in the terminal 10 is data related to a data processing function for information display, the filtering unit 130 may filter (select) have.

On the other hand, for example, when the current data generated/received in connection with the app 15 executed in the terminal 10 is data related to a data analysis function for image analysis based on large data, the filtering unit 130 filters It can be delivered to the core network 1 without (optional).

In this case, in detail, the filtering unit 130 uses the core network 1 based on the user context of the terminal 10 for other data (eg, image analysis data) that is not filtered (selected). Delivered to the core network (1), the service subject providing the cloud service, that is, the core cloud node 200 may request a resource-based cloud service pre-assigned to the user according to the user context.

In this case, the data transmitted to the core cloud node 200 without being filtered by the edge cloud node 100 is assigned to the corresponding user of the terminal 10 in the core cloud node 200 interworking with the big data (storage node). It will be processed based on the resource that was created, that is, based on the user context.

In addition, the core cloud node 200 stores the result of data calculation processing, which is computed based on resources allocated to a corresponding user of the terminal 10, in an internal storage or a storage node interworking based on a user context, and the terminal Based on the user context of (10), it can be provided (delivered) to the app 15 of the terminal 10 through the edge cloud node 100 to provide a cloud service based on the user context.

The application execution unit 140A calculates and processes the data (for example, information display data) selected by the filtering unit 130 based on the application execution resource allocated by the resource allocation unit 120, and performs cloud service. Provides distributed with the core cloud node 200.

Specifically, the application execution unit 140A is executed based on a virtual machine (VM) operating based on the user context of the terminal and a virtualization terminal according to the operation of the virtual machine (VM), and the filtering unit It may be composed of a virtual application (Virtual Application, vApp) to process the selected (filtered) data on behalf of the app 15 in the terminal 10.

In addition, the application execution unit 140A composed of the virtual machine (VM) and the virtual application (vApp) is preferably configured and operated in the application execution resource allocated by the resource allocation unit 120 when the terminal 10 is connected. .

More specifically, for example, in the case of configuring the application execution unit in an app unit in the present invention, on the premise that the application running on the terminal 10 at the time of connection to the terminal 10 is the app 15, the terminal 10 The application execution unit 140A may be configured in the application execution resource allocated to the application execution unit for the new application in the application execution resource allocated to the terminal 10 when the new app is additionally executed in the terminal 10 ( 140B) may be further configured.

In addition, the application execution unit 140A composed of a virtual machine (VM) and a virtual application (vApp) is preferably removed from the application execution resource previously allocated by the resource allocation unit 120 when the terminal 10 is connected. .

More specifically, for example, if the application execution unit is configured in an app unit in the present invention, the application execution unit 140A may be removed from the application execution resource allocated to the terminal 10 when the terminal 10 connection is terminated. Also, even if the connection of the terminal 10 is not terminated, it may be removed from the application execution resource allocated to the terminal 10 when the app 10 is terminated.

Again, referring to the application execution unit 140A, a process of providing a cloud service in a distributed manner is as follows.

Application Execution Unit 140A Specifically, a vApp executed based on a virtualization terminal (user context of the terminal 10) is selected by the filtering unit 130 based on the application execution resource allocated by the resource allocation unit 120 ( Filtering) computes the processed data, and provides a cloud service with the core cloud node 200.

The application execution unit 140A, that is, the vApp, computes and processes data based on a storage node (not shown) located at the base station 20 terminal to which the terminal 10 accesses for connection with the core network 1. It is preferred.

For example, if the data selected (filtered) by the filtering unit 110 is information display data, the application execution unit 140A, that is, the vApp processes the data based on the data stored in the storage node (not shown). By generating (information display screen), the cloud service may be distributed with the core cloud node 200.

At this time, the interlocked storage node (not shown) may be storage of a separate MEC node as described above, or may be storage of a MEC node included in the edge cloud node 100, and a storage node separate from the MEC node. It may be.

Accordingly, the data filtered by the edge cloud node 100 is computed and processed by the application execution resource and the application execution unit 140A configured to be dynamically allocated by the edge cloud node 100, so that the edge cloud node 100 May selectively provide a distributed cloud service (specific function) through filtering (optional) data operation processing for the app 15 in the terminal 10.

Here, a specific function of the cloud service may be changed according to a preset distribution policy.

Therefore, depending on how the distribution policy is set, the data filtered by the filtering unit 130 will change, and eventually the cloud service (specific function) provided by the edge cloud node 100 will change.

As described above, the distributed policy affecting data filtering of the filtering unit 130 is in a function range of a cloud service capable of supporting data stored in a storage node (not shown), a type of an app (data service), and an app (data service). It may be set based on at least one of the required computation amount and service speed.

However, as the function range of a cloud service capable of supporting data stored in a storage node (not shown) is larger, the distributed policy is such that the edge cloud node 100 filters data services that require a larger amount of computation than when the function range is small. Can be set.

In addition, as the real-time guarantee of the type of the app (data service) is important, a distributed policy may be set to filter in the edge cloud node 100 in the opposite case.

In addition, the smaller the amount of computation required by the app (data service) and the faster the service speed, the distributed policy may be set to filter in the edge cloud node 100 as opposed to the opposite case.

That is, in the present invention, it is to propose a control framework (Management Framework) that can control the distribution of the cloud service through the distribution policy setting.

The terminal interworking unit 110 specifically displays the result (eg, the information display screen) of the operation result (eg, the information display screen) of the application execution unit 140A (eg, the information display screen). Provides as an app 15.

At this time, the result of calculating and processing the data in the application execution unit 140A is preferably provided to the terminal 10 in a streaming manner by the terminal interworking unit 110.

That is, the result (for example, an information display screen) processed by the data in the edge cloud node 100 is provided to the terminal 10 in a streaming manner, and the app 15 running in the terminal 10 receives streaming data ( Hereinafter, App Streaming) can be immediately output (eg, display) without additional calculation processing.

On the other hand, the terminal interworking unit 110, when the data delivered to the core network (1) receives a result of the calculation processing by the service provider that provides the cloud service in the core network (1), that is, the core cloud node 200, This is provided to the terminal 10, specifically, the app 15.

Accordingly, the edge cloud node 100 of the present invention is located closer to the user (terminal) than the core cloud node 200 that provides a user context-based cloud service in the core network 1, and resources are dynamically allocated. Through the application execution unit configured in (application execution resource), a cloud service (specific function) based on a user context may be distributed.

In addition, the edge cloud node 100 of the present invention may further include a storage interlocking unit 150.

The storage interworking unit 150 provides the cloud service at the core network (1) stage by delivering the result of the data processing and processing by the application execution unit (140A) to the core network (1) stage based on the user context of the terminal. To share with the service subject, that is, the core cloud node 200.

In detail, for example, the storage interworking unit 150 sets the user context of the terminal 10 to a storage node (not shown) in which the edge cloud node 100 interlocks the data calculation processing result of the application execution unit 140A. Stored on the basis, it can be provided to the core cloud node 200 based on the user context of the terminal 10 to be shared with the core cloud node 200.

In this case, the result of the cloud service (specific function) provided by the edge cloud node 100 distributedly is stored in the edge cloud node 100 side that performed the cloud service (specific function), and the corresponding cloud service (specific function) is stored. Although not actually performed, it is also stored in a shared manner on the core cloud node 200 side.

Accordingly, in the present invention, even if the edge cloud node 100 of the base station stage and the core cloud node 200 on the network provide distributed cloud services, each of the edge cloud node 100 and the core cloud node 200 provides cloud services. A storage state that can be normally provided may be maintained.

As described above, in the present invention, the user (terminal) than the core cloud node 200 and the core cloud node 200 that provides a cloud service provided for an app running on the terminal based on a user context. ) To provide a distributed structure (cloud service-based hybrid application execution environment) provided by the edge cloud node 100, which is provided based on the user context, and partially (specific functions) cloud service (cloud) in the data collection section. Computing) becomes possible.

In this case, as shown in FIG. 1, in the case of the cloud service selectively provided by the edge cloud node 100, the service delay (Latency_Edge in FIG. 1) is superior to the existing cloud-based application execution environment (Latency_Core in FIG. 1). In the case of the cloud service provided by the core cloud node 200, the service reliability (because it can process and process large amounts of data at high speed as in the existing cloud-based application execution environment) precision will not deteriorate.

In addition, in the present invention, by providing a cloud service through an application execution unit configured in a resource (application execution resource) to which the edge cloud node 100 is dynamically allocated/recovered, creating a recyclable environment for resources for the cloud service Therefore, it is possible to expect performance improvement to enable ultra low latency/large data service.

In addition, in the present invention, a core cloud node and a plurality of edge cloud nodes propose a cloud computing platform (distributed cloud computing system) having a fluid structure in which cloud services are distributed, thereby realizing distributed cloud services. It is possible to provide a structural environment capable of flexible resource interlocking (association) without having a separate central device.

In addition, in the present invention, due to the above-mentioned effects, that is, the effect of enabling flexible resource interlocking (association) while reducing service latency, reducing traffic at the core network stage and flexible scalability of edge cloud nodes. Various side effects can be expected.

Hereinafter, an operation method of an edge cloud node (device) according to a preferred embodiment of the present invention will be described with reference to FIG. 3.

According to the operation method of the edge cloud node 100 of the present invention, a distribution policy affecting data filtering is pre-set (S100).

According to the operation method of the edge cloud node 100 of the present invention, the edge cloud node 100 recognizes a specific application executed in the terminal 10 when the connected terminal 10 is confirmed (S110) (S120). .

Hereinafter, for convenience of description, it is assumed that the app 15 is executed in the terminal 10.

According to the operation method of the edge cloud node 100 of the present invention, the edge cloud node 100 allocates application execution resources for the app 15 running on the terminal 10 (S130).

That is, the edge cloud node 100 may immediately allocate the application execution resource for the app 15 running on the terminal 10 from the computing resource for processing the data operation held by the edge cloud node 100.

In addition, according to the operation method of the edge cloud node 100 of the present invention, the edge cloud node 100 is an application execution unit including a virtual machine (VM) and a virtual application (vApp) in the application execution resource allocated in step S130. Configure (140A) (S140).

That is, the application execution unit 140A is executed based on a virtual machine (VM) operating based on a user context and a virtualization terminal according to the operation of the virtual machine (VM) to transmit data in the terminal 10. It is composed of a virtual application (vApp) that processes and operates on behalf of the app 15.

In addition, according to the operation method of the edge cloud node 100 of the present invention, the edge cloud node 100 receives data generated in connection with the app 15 executed in the terminal 10 (S150). It is determined whether the data is data related to a specific function of a core cloud node 200 located in the core network 1 and a cloud service that is distributed and provided (S160).

At this time, the data generated in connection with the app 15 includes data generated in the app 15 in the terminal 10, specifically the request data, response data, report data, etc., and the corresponding data. It includes data (eg, collected data, report data, etc.) generated from a separate sensing device (not shown) built for service.

That is, the edge cloud node 100 of the data generated in connection with the app 15 running on the terminal 10, of the core cloud node 200 located in the core network (1) and the cloud service to provide distributed Filter/select only data related to a specific function (S160 Yes), and transfer other data to the core network 1 (S160 No).

For example, when the current data generated/received in connection with the app 15 executed in the terminal 10 is data related to a data processing function for information display, the edge cloud node 100 filters (selects). It can be done (S160 Yes).

On the other hand, for example, when the current data generated/received in connection with the app 15 executed in the terminal 10 is data related to a data analysis function for image analysis based on large data, the edge cloud node 100 , It can be delivered to the core network (1) without filtering (selection) (S160 No).

In this case, in detail, the edge cloud node 100 uses the core network (1) based on the user context of the terminal 10 for other data (eg, image analysis data) that has not been filtered (selected). By transmitting to the stage (S210), the core cloud node 200 of the core network (1) may request a resource-based cloud service previously allocated to a user according to a user context.

In this case, the data transmitted to the core cloud node 200 without being filtered by the edge cloud node 100 is assigned to the corresponding user of the terminal 10 in the core cloud node 200 interworking with the big data (storage node). It will be processed based on the resource, that is, based on the user context (S220).

In addition, the core cloud node 200 stores the result of data calculation processing, which is computed based on resources allocated to a corresponding user of the terminal 10, in an internal storage or a storage node interworking based on a user context, and the terminal By passing to the edge cloud node 100 based on the user context of (10) (S230), the edge cloud node 100 to provide the result of the data operation processing transferred to the app 15 of the terminal 10 Will do (S240).

On the other hand, according to the operation method of the edge cloud node 100 of the present invention, the edge cloud node 100 calculates and processes the data (for example, information display data) selected (filtered) in step S160 (S170). The service is distributed with the core cloud node 200.

That is, the edge cloud node 100, the application execution resource allocated in step S130, through the vApp executed based on the application execution unit 140A specifically configured in step S140, specifically the virtualization terminal (user context of the terminal 10). Based on the data processing processing, the cloud service is distributed to the core cloud node 200.

The application execution unit 140A of the edge cloud node 100, that is, the vApp, stores a storage node (not shown) located at the terminal of the base station 20 that the terminal 10 accesses for connection with the core network 1. It is desirable to process the data based on it.

For example, when the data selected (filtered) in step S160 is information display data, the application execution unit 140A, that is, the vApp processes the data based on the data stored in the storage node (not shown) (information display screen) Generated), the cloud service may be distributed with the core cloud node 200.

Accordingly, the data filtered by the edge cloud node 100 is computed and processed by the application execution resource and the application execution unit 140A configured to be dynamically allocated by the edge cloud node 100, so that the edge cloud node 100 May selectively provide a distributed cloud service (specific function) through filtering (optional) data operation processing for the app 15 in the terminal 10.

In addition, according to the operation method of the edge cloud node 100 of the present invention, the edge cloud node 100 calculates and processes data (for example, information display data) in the application execution unit 140A (for example, information display screen generation). One result (for example, an information display screen) is provided to the terminal 10, specifically, to the app 15 in a streaming manner (S180).

That is, the result (for example, an information display screen) processed by the data in the edge cloud node 100 is provided to the terminal 10 in a streaming manner, and the app 15 running in the terminal 10 receives streaming data ( Hereinafter, App Streaming) can be immediately output (eg, display) without additional calculation processing.

In addition, according to the operation method of the edge cloud node 100 of the present invention, the edge cloud node 100 is a storage node that the edge cloud node 100 interlocks with the result of calculating and processing data in the application execution unit 140A. Stored based on the user context of the terminal 10 in (not shown), but provided to the core cloud node 200 based on the user context of the terminal 10 to be shared with the core cloud node 200 (S190) ).

In this case, the result of the cloud service (specific function) provided by the edge cloud node 100 distributedly is stored in the edge cloud node 100 side that performed the cloud service (specific function), and the corresponding cloud service (specific function) is stored. Although not actually performed, the core cloud node 200 is also stored based on the user context (S200).
