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

A mobile edge computing node (hereinafter referred to as MEC node) is a server-type node provided at a base station so as to store a large amount of data frequently used by a user or required to be transmitted quickly and to transmit the requested data immediately upon request.

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

The edge cloud node 100 includes a terminal interlocking unit 110 interlocked with a connected terminal 10, A resource allocation unit 120 for allocating an application execution resource for a specific application executed in the application 15 or the application 15 and a resource allocation unit 120 for allocating application execution resources for the application 15 in the core network 1, A filtering unit 130 for selecting data related to a specific function of the cloud service provided to the core network 1 and transmitting the other data to the core network 1, And an application execution unit 140A that distributes and provides the cloud service.

Hereinafter, for ease of explanation, reference will be made to the reference numerals shown in Fig.

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

That is, the terminal interlocking unit 110 can confirm the terminal 10 connected through the predetermined authentication procedure, or can check the unspecified terminal 10 connected without the authentication procedure.

At this time, the manner in which the terminal 10 is connected to the edge cloud node 100, more specifically, the terminal interlocking unit 110, is a method in which the edge cloud node searching function mounted on the terminal 10 searches and connects the edge cloud node 100 Can be realized.

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

The terminal interlocking unit 110 receives the data (e.g., request data, response data, report data, etc.) from the terminal 10 to which the connection is confirmed and transmits data (e.g., Streaming) is transmitted, and can be interworked with the terminal 10.

The resource assignment unit 120 allocates an application execution resource for the application 15 executed in the terminal 10 when the terminal 10 is connected.

That is, when the connection of the terminal 10 in the terminal interworking unit 110 is confirmed, the resource assignment unit 120 determines that the terminal 10 is connected to the computing resource for the data operation processing held by the edge cloud node 100, The application execution resources for the application 15 to be executed in the application 15 can be immediately allocated.

The resource assignment unit 120 may also collect the application execution resources allocated for the application 15 executed in the terminal 10 when the termination of connection of the terminal 10 is confirmed in the terminal interlock unit 110 can do.

The filtering unit 130 stores data related to the specific function of the cloud service provided by the core network 1 to the app 15 among data generated in association with the app 15 executed in the terminal 10 And transmits the other data to the core network 1. [

Here, the data generated in relation to the app 15 means data generated in association with the data service provided by the app 15 as described above.

That is, the data generated in association with the application 15 is data (e.g., request data, response data, report data, etc.) generated in the application 15 in the terminal 10, specifically, (E.g., collected data, report data, etc.) generated from a separate sensing device (not shown) built for the service.

That is, the filtering unit 130 determines whether or not the cloud service is distributed to the core cloud node 200 located in the core network 1 among the data generated in association with the application 15 executed in the terminal 10 Only the data related to the function is selected (selected), and other data is transmitted to the core network 1.

For example, when the present data generated / received in association with the application 15 executed in the terminal 10 is data related to a data processing function for displaying information, the filtering unit 130 can filter (select) have.

On the other hand, for example, when the current data generated / received in association with the application 15 executed in the terminal 10 is data related to a data analysis function for image analysis based on a large capacity data, the filtering unit 130 performs filtering (Not selected) to the core network 1.

More specifically, the filtering unit 130 extracts other data (e.g., image analysis data) not filtered (selected) from the core network 1 based on the user context of the terminal 10 To the service provider providing the cloud service in the core network 1, that is, the core cloud node 200, a resource based cloud service that is pre-allocated to the user according to the user context.

Data to be transmitted to the core cloud node 200 without being filtered by the edge cloud node 100 is allocated to the corresponding user of the terminal 10 in the core cloud node 200 interworking with the big data (storage node) Based on the resource, that is, based on the user context.

The core cloud node 200 stores the result of the data operation processing operation based on the resource allocated to the user of the terminal 10 in the internal storage or the storage node that cooperates with the user based on the user context, (Delivered) to the app 15 of the terminal 10 through the edge cloud node 100 based on the user context of the user terminal 10 to provide a cloud service based on the user context.

The application execution unit 140A computes data (for example, information display data) selected (filtered) by the filtering unit 130 based on application execution resources allocated by the resource assignment unit 120 and generates a cloud service Distributed to the core cloud node 200.

More specifically, the application execution unit 140A includes a virtual machine (VM) operating on the basis of the user context of the terminal, a virtual machine (VM) based on the operation of the virtual machine A virtual application (vApp) for performing arithmetic processing on data selected (filtered) by the application 130 in place of the app 15 in the terminal 10. [

The application execution unit 140A configured by the virtual machine (VM) and the virtual application (vApp) is preferably constituted and operated on the application execution resource allocated by the resource assignment unit 120 in the connection of the terminal 10 .

More specifically, for example, in the present invention, when the application execution unit is configured on an application-by-app basis, when the application running on the terminal 10 at the time of connection of the terminal 10 is an application 15, The application execution unit 140A can be configured to the application execution resource allocated to the terminal 10. When a new application is additionally executed in the terminal 10, the application execution unit allocated to the application execution resource allocated to the terminal 10 140B may be further configured.

The application execution unit 140A configured by the virtual machine (VM) and the virtual application (vApp) is preferably removed from the application execution resource allocated by the resource assignment unit 120 at the end of connection of the terminal 10 .

More specifically, for example, in the present invention, when the application execution unit is configured on an application-by-app basis, the application execution unit 140A may be removed from the application execution resource allocated to the terminal 10 upon termination of the connection to the terminal 10 And may be removed from the application execution resources allocated to the terminal 10 at the end of execution of the application 10 even if the connection of the terminal 10 is not terminated.

Hereinafter, a process of distributing a cloud service by referring to the application execution unit 140A will be described.

Specifically, the vApp executed on the basis of the virtualization terminal (the user context of the terminal 10) is selected by the filtering unit 130 based on the application execution resources allocated by the resource assignment unit 120 And processes the data to provide the cloud service to the core cloud node 200 in a distributed manner.

The application execution unit 140A or vApp performs data processing based on a storage node (not shown) located at the end of the base station 20 to which the terminal 10 connects for connection with the core network 1 .

For example, when the data selected (filtered) by the filtering unit 110 is information display data, the application executing unit 140A, that is, the vApp, processes the data based on the data stored in the storage node (Generate an information display screen), and provide the cloud service to the core cloud node 200 in a distributed manner.

The storage node (not shown) that is interlocked at this time may be a storage of a separate MEC node as described above, or may be a storage of an MEC node included in the edge cloud node 100, Lt; / RTI >

The data filtered by the edge cloud node 100 is processed by the application execution resources dynamically allocated in the edge cloud node 100 and the application execution unit 140A included therein, Can selectively distribute cloud services (specific functions) through filtering (selection) data processing to the app 15 in the terminal 10. [

Here, the specific function of the cloud service can be changed according to the predetermined distribution policy.

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

The distribution policy that affects the data filtering of the filtering unit 130 may be a function range of a cloud service capable of supporting data stored in a storage node (not shown), a type of an application (data service), an application And may be set based on at least one of a required computation amount and a service speed.

It should be noted that the distributed policy is set so that the edge cloud node 100 filters the data service requesting a larger calculation amount in the case where the functional range of the cloud service capable of supporting the data stored in the storage node (not shown) is large, Can be set.

In addition, the distribution policy can be set so that the type of the app (data service) is important in real time, and in the opposite case, the contrast edge cloud node 100 filters.

In addition, a distributed policy may be set so that the amount of computation required by the application (data service) is small and the service speed is high, and in the opposite case, the contrast edge node 100 filters.

That is, the present invention proposes a control framework that can control distribution of cloud services through a distribution policy setting.

The terminal interlocking unit 110 transmits a result (for example, an information display screen) obtained by computing (e.g., generating an information display screen) data (e.g., information display data) in the application execution unit 140A to the terminal 10 specifically To the app 15.

At this time, it is preferable that the result of the operation processing of the data by the application executing unit 140A is provided to the terminal 10 by the terminal interlocking unit 110 in a streaming manner.

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

When the data transmitted to the core network 1 is received by the service provider providing the cloud service in the core network 1, that is, the result of the operation performed by the core cloud node 200, And provides it to the terminal 10, specifically to the application 15.

The edge cloud node 100 of the present invention is located closer to the user (terminal) than the core cloud node 200 providing the cloud service based on the user context in the core network 1, (A specific function) based on the user context through the application execution unit configured in the application execution resource (application execution resource).

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

The storyline delaying unit 150 transmits the result of the operation processing of the data in the application executing unit 140A to the core network 1 based on the user context of the terminal and provides the cloud service in the core network 1 That is, the core cloud node 200.

Concretely, for example, the storyline delaying unit 150 stores the result of the data operation of the application executing unit 140A in a storage node (not shown) in which the edge cloud node 100 is linked with the user context of the terminal 10 And may be provided to the core cloud node 200 based on the user context of the terminal 10 and shared with the core cloud node 200. [

In this case, the result of the cloud service (specific function) distributed and provided by the edge cloud node 100 is stored in the edge cloud node 100 that has performed the corresponding cloud service (specific function), and the corresponding cloud service It is stored in a shared manner on the core cloud node 200 side.

The edge cloud node 100 and the core cloud node 200 each provide a cloud service even if the cloud service is distributed from the edge cloud node 100 of the base station and the core cloud node 200 on the network. Storage conditions that can be provided normally can be maintained.

According to the operation method of the edge cloud node 100 of the present invention, the edge cloud node 100 performs operation processing (S170) on data (e.g., information display data) selected (filtered) Service to the core cloud node 200 in a distributed manner.

That is, the edge cloud node 100 determines whether or not the application execution unit 140A configured in step S140, specifically the application execution resource allocated in step S130, through the vApp executed based on the virtualization terminal (the user context of the terminal 10) And distributes the cloud service to the core cloud node 200 in a distributed manner.

The application execution unit 140A or vApp of the edge cloud node 100 has a storage node (not shown) located at the end of the base station 20 to which the terminal 10 connects for connection with the core network 1 It is preferable that the data is subjected to arithmetic processing.

For example, when the data selected (filtered) in step S160 is information display data, the application executing unit 140A, that is, the vApp, performs arithmetic processing based on data stored in a storage node (not shown) And provide the cloud service to the core cloud node 200 in a distributed manner.

The data filtered by the edge cloud node 100 is processed by the application execution resources dynamically allocated in the edge cloud node 100 and the application execution unit 140A included therein, Can selectively distribute cloud services (specific functions) through filtering (selection) data processing to the app 15 in the terminal 10. [

According to the method of operating the edge cloud node 100 of the present invention, the edge cloud node 100 performs processing (e.g., generating an information display screen) of data (e.g., information display data) in the application execution unit 140A, And provides a result (for example, an information display screen) to the terminal 15 (specifically, the application 15) in a streaming manner (S180).

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

According to the method of operating the edge cloud node 100 of the present invention, the edge cloud node 100 may store the result of the operation of the data by the application execution unit 140A in the storage node 100, which is connected to the edge cloud node 100, (Not shown) based on the user context of the terminal 10, and may provide the same to the core cloud node 200 based on the user context of the terminal 10 and may be shared with the core cloud node 200 ).

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