Edge connection management device and operation method of edge connection management device

The present invention, when the same application for the edge service is installed in each of the Mobile Edge Computing Sites distributed and arranged for each country to enable terminal access, through the Mobile Edge Computing Site closest to the terminal to access. It is about a plan to provide edge services.

In an existing mobile communication network, for reasons such as mobility management and billing, a method in which all traffic generated from a terminal is delivered to a central SP-GW (SGW, PGW) was common.

In this centralized network structure, services such as telephony (IMS), Internet access, and messaging/video through various portals/OTTs, which are mainly used in terminals (e.g., smartphones), are not very sensitive to delay and must have large capacity. There was no big problem in using it as it was as small as several tens of Mbps.

However, in recent years, terminals connected to the mobile communication network have been diversified into objects such as cars, drones, sensors, VR headsets, cameras, and robots as well as existing smartphones (humans), and services required by each terminal have been diversified. Ultra-low latency (RTT) within ms to 10ms is required, and large-capacity bandwidths from hundreds of Mbps to several Gbps per stream have been required.

In this regard, as a technology to meet these needs, an infrastructure for edge services is configured on a Mobile Edge Computing Site placed near a terminal to provide ultra-low latency and large-capacity applications. Acceptable mobile edge computing (MEC, Mobile Edge Computing) technology is attracting attention.

In the edge service environment to which mobile edge computing technology is applied, a host server is configured to provide edge virtual resources to customers using edge services for each distributed mobile edge computing site that terminals can access, and terminals access edge virtual resources. Edge service can be implemented by setting and providing access information (IP/URL) for access.

However, in such an edge service environment, mobile edge computing sites accessible to terminals are distributed and arranged for each country, and accordingly, the physical distance for connection between each mobile edge computing site and terminal is different.

Therefore, despite the characteristics of the edge service environment requiring ultra-low latency, the performance of the edge service (edge service flow latency) provided to the terminal may vary greatly for each mobile edge computing site.

The present invention was created in view of the above circumstances, and the purpose to be reached in the present invention is that the same application for edge service is provided for each Mobile Edge Computing Site distributed and arranged for each country so that terminal access is possible. When installed, it is to induce access of the terminal to the mobile edge computing site closest to the terminal.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In one embodiment of the present invention, mobile edge computing (MEC, Multi-Access Edge Computing) technology is dealt with.

In the edge service environment based on these mobile edge computing technologies, service performance improvements such as ultra-low latency and large-capacity applications can be expected as the infrastructure for edge services is configured at the edge cloud site (MEC Site) close to which terminals can access. can

However, in an edge service environment to which mobile edge computing technology is applied, mobile edge computing sites that terminals can access can be distributed and arranged for each country, and accordingly, the physical distance for connection between each mobile edge computing site and terminal is different. .

Therefore, despite the characteristics of the edge service environment requiring ultra-low latency, the performance of the edge service (edge service flow latency) provided to the terminal may vary greatly for each mobile edge computing site.

Therefore, considering the environment in which the same application for the edge service is installed at each mobile edge computing site deployed for each station to which the terminal can access, in order to implement the ultra-low latency edge service, the mobile station of the nearest station to which the terminal can access It is necessary to provide edge services through edge computing sites.

In this regard, as a method for providing an edge service through a mobile edge computing site of a country closest to a terminal to access, a method of utilizing a DNS (Domain Name System) may be considered.

However, in the case of telecommunication companies, since DNS is built in the form of a centralized system, it is impossible to find a mobile edge computing site that can provide edge services at the location closest to the terminal.

In other words, in order to check the mobile edge computing site closest to the terminal, a method of specifying the location of the terminal from the source (Src) IP of the terminal may be applied, but as the DNS server of the carrier side transmits the DNS message, Due to the characteristics of recursive DNS query, the IP of the DNS server instead of the terminal is inserted into the source (Src) IP, so the location of the terminal cannot be specified.

Therefore, in the 3GPP SA6 standard, ECS (Edge Configuration Server) / EES (Edge Enable Server), AWS uses AWS Pulse, and in the case of telecommunication companies, a separate system replaces DNS to teach the terminal the application address installed in the nearest mobile edge computing site. following the giving method.

However, in order to build such a DNS replacement system, in the case of the 3GPP SA6 standard, it is necessary to develop EEC (Edge Enable Client) at the terminal level, and in the case of AWS, terminal development based on Pulse API is required. A separate API must be developed for

After all, in order to build the above-mentioned DNS replacement system in order to identify the mobile edge computing site closest to the terminal, development of a separate SDK or API is required at the terminal level, which can be a major barrier to entry to edge service development. .

Accordingly, in one embodiment of the present invention, a new method for providing an edge service through a mobile edge computing site of a country closest to a terminal to access is proposed.

As shown in FIG. 1, in the edge service environment according to an embodiment of the present invention, the same application for the edge service is installed at each mobile edge computing site (MEC Site A, MEC Site B) deployed for each country terminal. When (10) wants to use the edge service, it may have a configuration including an edge connection management device 20 that induces access to an application installed in a mobile edge computing site closest to the terminal 10.

Here, the edge access management device 20 is the DNS server 30 of the customer company side, which is the subject that installs the same application for the edge service for each mobile edge computing site (MEC Site A, MEC Site B) for each country, and the carrier side By linking with the DNS server 40, connection to an application installed on a mobile edge computing site closest to the terminal 10 can be induced.

The edge access management device 20 may be understood as a configuration that performs, for example, the EES/ECS role of 3GPP SA6 as a kind of access policy management system.

On the other hand, the edge service environment according to an embodiment of the present invention may have a configuration further including a biz portal server 50 that provides an interface to the customer company in relation to application installation.

Above, in the edge service environment according to an embodiment of the present invention, the edge service can be provided through the mobile edge computing site (MEC Site A or MEC Site B) of the country closest to the terminal 10. The configuration of the edge access management device 20 for the purpose will be described in more detail.

2 shows a schematic configuration of an edge connection management device 20 according to an embodiment of the present invention.

As shown in FIG. 2, the edge access management device 20 according to an embodiment of the present invention includes an access management unit 21 that manages access information for applications installed for edge services for each mobile edge computing site for each country. , and a connection inducing unit 22 for inducing connection of the terminal 10 to an application installed for each mobile edge computing site for each country.

The entire configuration or at least a part of the edge connection management device 20 may be implemented in the form of a hardware module or a software module, or a combination of a hardware module and a software module.

Here, the software module may be understood as, for example, a command executed by a processor that processes an operation within the edge connection management device 20, and these commands are loaded in a separate memory within the edge connection management device 20. can have a shape.

On the other hand, the edge access management device 20 according to an embodiment of the present invention provides an interface to the customer company in connection with installing the same application for the edge service for each mobile edge computing site for each country, in addition to the above configuration. It may have a configuration further including a communication unit 23 in charge of actual communication functions with the portal server 50 and other components.

The communication unit 23 includes, for example, an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, and a memory, but is not limited thereto. Known circuits to perform may include all.

Based on the configuration described above, the 5G base station 20 according to an embodiment of the present invention provides a mobile edge closest to the terminal 10 in an environment in which the same application for the edge service is installed at each mobile edge computing site deployed for each country. Connection of the terminal 10 to the application installed on the computing site can be induced. Hereinafter, a more detailed description of the configuration within the edge access management device 20 for realizing this will be continued.

The access management unit 21 performs a function of managing access information for applications installed for edge services.

More specifically, the access management unit 21 allocates and manages a representative IP for the same application installed for the edge service at each mobile edge computing site deployed for each country.

At this time, if the access management unit 21 confirms that the same application for the edge service is installed for each mobile edge computing site deployed for each country through the biz portal server 50 at the request of the customer company, the domain name and A representative IP for matching can be allocated.

In addition, when a representative IP is assigned to the same application installed in each mobile edge computing site for each country, the access management unit 21, for example, as shown in [Table 1] below, uses the application identification information (App ID) as the representative IP (Rep. IP), and for the divided representative IP (Rep. IP), it is possible to manage by matching the individual IP (App IP) assigned to the application at the mobile edge computing site of each bureau (A, B).

App ID Rep. IP national history App IP abc 100.100.1.1 National History A 210.100.1.1 National History B 220.100.1.1 pqr 100.100.1.2 National History A 210.100.2.1 National History B 220.100.2.1

On the other hand, the representative IP assigned to the application is transmitted to the customer as an IP for DNS through the biz portal server 50 that provides the interface to the customer. It is managed by matching with the domain name (www.abc.com) of the domain name (www.abc.com). In this regard, in FIG. 3, in order to help the understanding of the description, the access information management procedure of the application implemented in the edge service environment according to an embodiment of the present invention is shown. is shown by way of example.

That is, the biz portal server 50 installs the same application for the edge service for each mobile edge computing site (Corporation A, B) deployed for each country at the request of the customer company (① - ④), and upon completion of the installation Representative IP allocation for applications can be requested by obtaining information on individual IPs allocated to applications from each mobile edge computing site and forwarding the information to the edge connection management device 20 (⑤).

In contrast, the edge access management device 20 allocates a representative IP for the same application installed at each mobile edge computing site for each country. When the representative IP is allocated to the application in this way, as shown in [Table 1] above, , The representative IP (Rep. IP) is classified by the application identification information (App ID), and for the divided representative IP (Rep. IP), the individual assigned to the application at the mobile edge computing site of each bureau (A, B) IP (App IP) is matched and managed (⑥).

Furthermore, the biz portal server 50 receives the representative IP assigned to the application from the edge access management device 20 and delivers it to the customer company as an IP for DNS (⑦, ⑧), and the DNS of the customer company that received it. In the server 30, the domain name (www.abc.com) of the application and the representative IP (100.100.1.1) are matched and managed (⑨, ⑩).

The connection inducing unit 22 performs a function of inducing connection to applications installed for each mobile edge computing site for each country.

More specifically, when the connection of the terminal 10, which has obtained the representative IP pre-allocated from the domain name of the application, is confirmed, the connection induction unit 22 determines the closest terminal to the terminal 10 based on the access information of the terminal 10. The individual IP assigned to the application at the mobile edge computing site of the government company is returned to the terminal 10 to induce access to the individual IP.

At this time, the connection induction unit 22 checks the application that the terminal 10 wants to access from the destination (Dest) IP in the access information of the terminal 10, and from the source (Src) IP in the access information of the terminal 100. A specific office to which the terminal 10 is connected to the network can be identified.

In this regard, when the terminal 10 attempts access through input of the domain name of the application, the representative IP that matches the domain name of the application through the DNS server 40 of the telecommunication company is sent from the DNS server 30 of the customer company. It can be acquired and connected to the edge access management device 20 .

At this time, the representative IP of the application obtained from the DNS server 30 of the customer company is set as the destination IP of the terminal 10, and Network Address Translation (NAT) corresponding to the official IP of the country where the network connection is made. The IP is set to the source (Src) IP of the terminal 10.

In this case, the connection induction unit 22 can check the application that the terminal 10 wants to access from the representative IP, which is the destination IP in the access information of the terminal 10, and the source in the access information of the terminal 10 ( From the NAT IP, which is Src) IP, it is possible to check a specific station through which the terminal 10 has access to the network.

On the other hand, in order to identify a specific station through which the terminal 10 is connected to the network from the NAT IP, it is of course required that information on the NAT IP assigned to each station should be set in advance.

In addition, when the specific station to which the terminal 10 is connected to the network is confirmed from the NAT IP, which is the source (Src) IP in the access information of the terminal 10, the access induction unit 22 among the mobile edge computing sites arranged for each station It is possible to identify a mobile edge computing site of the station that matches or is closest to the specific station, and returns an individual IP assigned to the application from the identified mobile edge computing site.

In this regard, FIG. 4 illustratively illustrates a procedure for inducing access to an application implemented in an edge service environment according to an embodiment of the present invention to aid understanding of the description.

That is, when the terminal 10 attempts access by inputting the domain name (www.abc.com) of the application, the representative IP that matches the domain name of the application through the DNS server 40 of the communication company is transferred to the DNS of the customer company. It is obtained from the server 30 (① - ④), and in this way, the representative IP of the obtained application is set as the destination (Dest) IP to access the connection management server 20 (⑤).

At this time, the source (Src) IP of the terminal 10 is set to a NAT IP, which is the public IP of the station through which the terminal 10 is connected to the network.

In this regard, the connection induction unit 22 checks the application (abc) that the terminal 10 wants to access from the representative IP (100.100.1.1), which is the destination IP in the access information of the terminal 10, and the terminal From the NAT IP, which is the source (Src) IP in the access information of (10), the specific bureau (office B) to which the terminal 10 has connected to the network is confirmed (⑥).

Furthermore, the connection induction unit 22, when a specific bureau (office B) to which the terminal 10 is connected to the network is confirmed from the NAT IP, which is the source (Src) IP in the access information of the terminal 10, mobile devices deployed for each bureau Among the edge computing sites, a mobile edge computing site disposed in the specific office (office B) is identified, and an individual IP (220.100.1.1) assigned to the application is returned to the terminal 10 from the mobile edge computing site. (⑦).

In this case, the terminal 10 sets the returned individual IP (220.100.1.1) as the destination IP and accesses the application to which the individual IP (220.100.1.1) is assigned, and accordingly, the terminal 10 is to be able to receive edge services from the application of the mobile edge computing site closest to oneself among a plurality of mobile edge computing sites where the same application is installed (⑧).

As described above, according to the configuration of the edge access management device 20 according to an embodiment of the present invention, mobile edge computing sites distributed and arranged for each country to enable access of the terminal 10 In an environment where the same application for each edge service is installed, by inducing access of the terminal 10 to the mobile edge computing site closest to the terminal 10 to access, the connection between the terminal 10 and the application when using the edge service is induced. As the physical distance is minimized, it can be seen that ultra-low latency edge service can be implemented.

Hereinafter, an operating method of the edge connection management device 20 according to an embodiment of the present invention will be described with reference to FIG. 5 .

At this time, if the access management unit 21 confirms that the same application for the edge service is installed for each mobile edge computing site deployed for each country through the biz portal server 50 at the request of the customer company, the domain name and A representative IP for matching can be allocated.

In addition, when a representative IP is assigned to the same application installed at each mobile edge computing site for each country, the access management unit 21 matches the assigned representative IP with the individual IP assigned to the application at each mobile edge computing site for management ( S14).

At this time, the access management unit 21 classifies the representative IP (Rep. IP) with the application identification information (App ID) as shown in [Table 1] previously illustrated, and for the divided representative IP (Rep. IP), each country office It can be managed by matching the individual IP (App IP) assigned to the application at the Mobile Edge Computing site of (Corporation A, B).

On the other hand, the representative IP assigned to the application is transmitted to the customer as an IP for DNS through the portal server 50 that provides the interface to the customer. It is managed by matching with the domain name (www.abc.com).

In contrast, the edge access management device 20 allocates a representative IP for the same application installed at each mobile edge computing site for each country. When the representative IP is allocated to the application in this way, as shown in [Table 1] above, , The representative IP (Rep. IP) is classified by the application identification information (App ID), and for the divided representative IP (Rep. IP), the individual assigned to the application at the mobile edge computing site of each bureau (A, B) IP (App IP) is matched and managed (⑥).

In this regard, the biz portal server 50 receives the representative IP assigned to the application from the edge access management device 20 and delivers it to the client company as an IP for DNS (⑦, ⑧), and the client side that receives it In the DNS server 30 of the application, the domain name (www.abc.com) and the representative IP (100.100.1.1) are matched and managed (⑨, ⑩).

Furthermore, when the access of the terminal 10 having obtained the pre-allocated representative IP from the domain name of the application is confirmed, the connection induction unit 22 determines the terminal 10 from the destination IP in the access information of the terminal 10. The application to be accessed is checked, and a specific station through which the terminal 10 is connected to the network is checked from the source (Src) IP in the access information of the terminal 100 (S14-S16).

In this regard, when the terminal 10 attempts access through input of the domain name of the application, the representative IP that matches the domain name of the application through the DNS server 40 of the telecommunication company is sent from the DNS server 30 of the customer company. It can be acquired and connected to the edge access management device 20 .

The IP is set to the source (Src) IP of the terminal 10.

In this case, the connection induction unit 22 can check the application that the terminal 10 wants to access from the representative IP, which is the destination IP in the access information of the terminal 10, and the source in the access information of the terminal 10 ( From the NAT IP, which is Src) IP, it is possible to check a specific station through which the terminal 10 has access to the network.

Thereafter, when the specific station to which the terminal 10 is connected to the network is confirmed from the NAT IP, which is the source (Src) IP in the access information of the terminal 10, the connection induction unit 22 among the mobile edge computing sites arranged for each station The mobile edge computing site of the station that matches or is located closest to the specific station is identified, and the individual IP assigned to the application is returned to the terminal 10 at the identified mobile edge computing site (S17).

In this regard, FIG. 4 exemplarily illustrates a procedure for inducing access to an application implemented in an edge service environment according to an embodiment of the present invention in order to help understanding of the description.

That is, when the terminal 10 attempts access by inputting the domain name (www.abc.com) of the application, the representative IP that matches the domain name of the application through the DNS server 40 of the communication company is transferred to the DNS of the customer company. It is obtained from the server 30 (① - ④), and in this way, the representative IP of the obtained application is set as the destination (Dest) IP to access the connection management server 20 (⑤).

At this time, the source (Src) IP of the terminal 10 is set to a NAT IP, which is the public IP of the station through which the terminal 10 is connected to the network.
