It is therefore desirable to sink traffic as much as possible to the edge of the network to enable local offloading of traffic. In a 5G ultra-reliable low-latency communication (URLLC) scene, ultra-reliable ultra-low latency communication needs to be provided, such as automatic driving, industrial control, telemedicine, etc., and the end-to-end high reliability of 99.999% and the end-to-end ultra-low latency of less than 1ms are required, thereby meeting higher requirements of the digital industry of people. It is also desirable to sink traffic to the edge of the network to reduce network latency associated with network traffic and multi-level traffic forwarding.
Mobile/multi-access edge computing (MEC) can meet the requirements in the above 5G application scenario. On one hand, the MEC is deployed at the edge of the network, the edge service runs on the terminal equipment, the feedback is quicker, and the problem of time delay is solved; on the other hand, the MEC sinks the content and the computing power, provides intelligent traffic scheduling, locally shunts the service, and locally caches the content, so that part of regional services can be terminated locally, thereby improving the service experience of users and reducing the resource occupation of a backbone transmission network and an upper core network. Thus, in the age of 5G, MEC will be the best choice for 5G network edge cloud deployment. However, when the MEC edge cloud is deployed, the related technical personnel often need to determine the deployment position of the MEC edge cloud through a large number of complicated calculation and analysis processes.

The following specifically describes a method for determining an MEC node provided by the present application, with reference to the accompanying drawings of the specification.
As shown in fig. 3, an embodiment of the present application provides a method for determining an MEC node, where the method includes the following steps:
s101, the determining device of the MEC node obtains a service demand area, service quality parameters of the service and deployment information of an application server of the service.
The service types of the services may include high-speed downloading, high-definition video, automatic driving, or industrial control. Different service types may correspond to different Service Level Agreement (SLA) indexes and quality of service (QoS) indexes.
In addition, the service demand area refers to an area where an operator needs to provide a communication service for the service when the user is performing the service, that is, an area where the service needs to deploy the MEC server. The service quality parameter of the service is specifically an SLA index and a QoS index corresponding to the service type of the service. The deployment information of the application server of the service may include information such as a deployment location and a network coverage of the application server of the service.
The application server of the service comprises a server which can provide the service for the current user. In this embodiment, the application server may be a server of an edge cloud of an MEC that has been deployed, such as a home host (micro host, mini host, etc.), an industrial gateway, a Customer Premise Equipment (CPE), and the like, which may provide an edge computing service.
The SLA metrics include Availability (Availability), Accuracy (Accuracy), system Capacity (Capacity), and Latency (Latency), among others. The QoS metrics may include resource type (e.g., GBR, non-GBR, Delay Critical GBR), expected Delay (PDB), Packet Error Rate (PER), Maximum Data Burst Volume (MDBV), data rate Averaging Window (Default Averaging Window), and so on.
It should be understood that in a 5G network, the quality of service parameter of the service may be a 5QI value of the service. Where the 5QI value is a scalar that can be used as a reference for the 5G QoS feature.
In some embodiments, before performing step S101, the determining device of the MEC node may receive a service request sent by the terminal device, where the service request may include information of a service type, a service location, and the like. The service location may be location information of the terminal device.
Correspondingly, after receiving a service request sent by a terminal device, the determining device of the MEC node may determine a service demand area, a service quality parameter of the service, and deployment information of an application server of the service according to a service type and a service location of the service request.
The service location may be location information of the terminal device, the service type may include high-speed downloading, high-definition video, automatic driving, industrial control, and the like, and the requirements of bandwidth, reliability, time delay, and the like of different service types are different, so that service demand areas of different services, service quality parameters of the services, and deployment information of the application servers of the services may be different.
S102, the MEC node determining device queries an MEC boundary database according to the service demand area to obtain a first node set.
The MEC boundary database is used for storing configuration information of each node in the network. For example, the MEC boundary database may include configuration information of each node within a geographic range operable by an operator.
Further, the configuration information of one node may include a deployment location of the node and at least one MEC area information. The method comprises the steps that an MEC area message corresponds to a service quality parameter, and the MEC area message is used for indicating at least one other node which can communicate with the node and meets the service quality parameter requirement corresponding to the MEC area message.
Illustratively, fig. 4 shows an MEC area information of one node. As shown in fig. 4, the node 21, the node 22, the node 23, the node 24, the node 25, the node 26, and the node 27 are other nodes capable of performing communication with the node 20 that satisfies the requirement of the quality of service parameter corresponding to the MEC area information.
The following describes a process of determining MEC zone information:
and S1, determining the MEC boundary node.
Illustratively, as shown in fig. 4, in the communication system, the node 20 may correspond to a plurality of transmittable paths, each including one or more other nodes.
On a transmittable path of a node, at least one node having a communication distance with the node smaller than or equal to the maximum communication distance is an MEC boundary node.
The maximum communication distance of a node may be determined according to the qos parameter, and the maximum communication distance may be understood as the farthest effective distance that the node can reach when sending the service data corresponding to the qos parameter, that is, the farthest distance that the node can perform communication meeting the qos parameter requirement.
And S2, determining the MEC area according to the MEC boundary nodes.
As shown in fig. 4, if the node 21, the node 23, the node 24, and the node 27 are the nodes having the maximum communication distance from the node 20 on the path 1, the path 2, the path 3, or the path 4, respectively, among the nodes having the communication distance from the node 20 that is less than or equal to the maximum communication distance from the node 20 under the quality of service parameter corresponding to the MEC area information, the MEC boundary node 21, the node 23, the node 24, and the node 27 of the node 20 are provided. Furthermore, boundary 1, boundary 2, boundary 3, and boundary 4 may be determined from the four MEC boundary nodes of the node 20, and boundary 1, boundary 2, boundary 3, and boundary 4 may constitute the MEC area of the node 20.
S3, the MEC area information is used to indicate at least one node within the MEC area.
The MEC area information of one node may indicate at least one other node in the MEC area of the quality of service parameter corresponding to the MEC area information, that is, at least one other node capable of performing communication meeting the requirement of the quality of service parameter corresponding to the MEC area information with the node.
Illustratively, as shown in fig. 4, MEC area information of the node 20 under the quality of service parameters of the traffic may be used to indicate the node 21, the node 22, the node 23, the node 24, the node 25, the node 26 and the node 27.
Optionally, the configuration information of the nodes in the MEC boundary database further includes: one or more of an identification of the node, a node type, network coverage, and frequency resources.
The identifier of the node is used to indicate the node, which may be a name or a serial number of the node, and has uniqueness. The node types comprise a base station, IDC, a backbone network node, a sink node, an access network node or a relay node. The network coverage of a node may be determined according to the signal coverage performance of the node, and thus, the network coverage of each node may be the same or different. The frequency resource of the node refers to a frequency band specified for use, and the richer the frequency resource is, the higher the transmission rate can be realized.
Optionally, in this embodiment of the present application, the service provided by the network node may be classified according to the QoS index and the SLA index, and the services at different levels may correspond to different QoS indexes and SLA indexes.
Illustratively, the traffic classification may be as shown in table 1:
TABLE 1
Further, in this embodiment of the present application, in at least one MEC area information of one node, one MEC area information corresponds to one service level.
Illustratively, the configuration information of one node may be as shown in table 2 below:
TABLE 2
Further, the MEC boundary database may store the service hierarchy shown in table 1 and the configuration information of the node shown in table 2. Therefore, the determining device of the MEC node queries the MEC boundary database according to the service quality parameter of the service, so as to obtain the service level of the service and further obtain the MEC region information corresponding to the service level of the service.
It should be understood that, before deploying the MEC server, the MEC node determining device may obtain directly available configuration information of the network service area of the operator, the node type, the deployment location, the network coverage area, and the like of each node in the network service area, and further determine at least one MEC area information of each node according to the above steps S1-S3. The MEC boundary database shown in table 1 is generated based on directly available configuration information of each node and MEC area information of each node.
In addition, the first node set includes at least one first node, and the first node is a node capable of providing service for a service demand area.
It should be understood that the coverage areas of all the first nodes in the first node set may be combined to form a first network service area of the first node set, and the first network service area may cover the service requirement area. Therefore, the first node is a candidate node of the deployable MEC server preliminarily determined by the determining device of the MEC node, and the first node set is a set of candidate nodes of the deployable MEC server preliminarily determined by the determining device of the MEC node.
S103, the MEC node determining device queries an MEC boundary database according to the deployment information of the application server and the service quality parameters of the service to obtain a second node set.
The second node set comprises at least one second node, and the second node is a node capable of communicating with the application server to meet the service quality parameter requirement of the service.
Optionally, the deployment information of the application server further includes an identifier of a node where the application server is located.
The identifier of the node where the application server is located has uniqueness, and one identifier may indicate one node. For example, the identifier of the node where the application server is located may be a node number, a node name, or other identifier capable of indicating the node.
In some embodiments, the MEC node determining device may search the target MEC area information from the MEC boundary database according to the identifier of the node where the application server is located and the service quality parameter of the service, and further form the second node set with the node where the application server is located and all nodes indicated by the target MEC area information.
The target MEC area information corresponds to the service quality parameter of the service, and belongs to the node where the application server is located.
It should be understood that the deployment location of the node where the application server is located is within the service demand area, and the node where the application server is located is a node that does not need to deploy the MEC server. And the node indicated by the target MEC area information can perform communication meeting the requirement of the service quality parameter of the service with the node where the application server is located, so that the node indicated by the target MEC area information is also a node without deploying an MEC server. Therefore, the second node set determined in step S103 is a set of nodes that do not need to deploy the MEC server.
S104, the determining device of the MEC node takes the difference of the first node set minus the second node set as a third node set.
The third node set comprises K third nodes, and K is a positive integer. It should be understood that the third set of nodes includes all nodes belonging to the first set of nodes but not to the second set of nodes.
It should be noted that, since the first node set is a set of candidate nodes capable of deploying the MEC server preliminarily determined by the determination device for the MEC node, and the second node set is a set of nodes not requiring to deploy the MEC server, the determination device for the MEC node subtracts the second node set from the first node set to obtain the candidate nodes requiring the MEC server in the first node set, and the third node set is a set of candidate nodes requiring to deploy the MEC server.
S105, the determining device of the MEC node selects at least one third node from the K third nodes as a node for deploying the MEC server.
The K third nodes are all candidate nodes which need the MEC server and are determined by the determination device of the MEC node.
It should be noted that, due to the difference between the service type, the user requirement, and the cost required for deploying the MEC server at each node, the operator may comprehensively analyze the actual service condition, and instruct the determining device of the MEC node to select at least one third node from the K third nodes as the node for deploying the MEC server.
As a possible implementation manner, the step S105 may be implemented as the following steps S1051 to S1054:
s1051, the determining device of the MEC node inquires the MEC boundary database according to the K third nodes in the third node set to obtain the network coverage of each third node in the K third nodes.
S1052, the determining device of the MEC node determines the second network service area according to the network coverage of the K third nodes.
And S1053, the determining device of the MEC node inquires the MEC boundary database according to the second network service area, and screens out M third nodes from the K third nodes.
Wherein M is a positive integer and is not more than K. Any one of the M third nodes is a node capable of providing a service meeting the service quality parameter requirements of the service in the second network service area.
S1054, the determining device of the MEC node selects at least one third node from the M third nodes as a node for deploying the MEC server.
It should be understood that, since M is less than or equal to K, the determining device of the MEC node selects at least one third node from the M third nodes as the node for deploying the MEC server, thereby further reducing the number of the nodes for deploying the MEC server and reducing the deployment cost of the MEC server.
In the embodiment of the application, based on the preset MEC boundary database, when the MEC server needs to be deployed, the node set for deploying the MEC server can be determined by querying configuration information of nodes in the MEC boundary database according to the service demand area, the service quality parameter of the service, and the deployment information of the application server of the service. According to the method for determining the MEC, a large number of complex calculation and analysis processes are not needed, and by inquiring the database, service personnel can quickly obtain the node set for deploying the MEC server, so that the analysis time of the service personnel can be reduced, and the deployment efficiency of the MEC server is improved.
Alternatively, based on the method shown in fig. 3, as shown in fig. 5, the step S102 may be implemented as the following steps S1021 to S1023:
and S1021, the determining device of the MEC node queries the MEC boundary database according to the service demand area to obtain a fourth node set.
The fourth node set comprises all fourth nodes located in the service demand area, and the node type of the fourth nodes is a base station.
Specifically, the MEC node determining device searches configuration information of each node recorded in the MEC boundary database according to the service demand area, extracts at least one fourth node in which the node position is in the service demand area and the node type is a base station, and the at least one fourth node forms the fourth node set.
It should be noted that, according to the combination of the network coverage ranges of the fourth nodes in the fourth node set, a fourth network service area may be formed, and the fourth network service area may cover the service demand area.
Optionally, the fourth node set may include all fourth nodes whose node positions are in the service requirement area and whose node types are base stations, or the fourth node set may also include N fourth nodes whose node positions are in the service requirement area and whose node types are base stations, where N is a positive integer.
The N fourth nodes belong to all fourth nodes whose node positions are in the service demand area and whose node types are base stations, and the N fourth nodes are the minimum nodes of which the fourth network service area can cover the service demand area. It should be understood that the smaller the nodes in the fourth node set, the fewer the nodes that the MEC node determination means finally determines need to deploy the MEC server, and thus, if the fourth node set includes N fourth nodes, the deployment cost of the MEC server may be reduced.
S1022, for each fourth node, the determining device of the MEC node finds all the nodes in the network coverage area of the fourth node from the MEC boundary database.
Specifically, the MEC node determining device may search the network coverage of each fourth node from the MEC boundary database, and determine all nodes whose deployment positions are within the network coverage of the fourth node according to the deployment position of each node in the MEC boundary database.
S1023, the MEC node determination device uses all fourth nodes included in the fourth node set and all nodes in the network coverage area of each fourth node to form the first node set.
It should be understood that each first node in the first node set is a candidate node where the MEC server may be deployed. Moreover, the network coverage of each first node in the first node set may cover the service demand area, so that the first node provides service for the service demand area.
Based on the above embodiment, the fourth node set may be obtained by querying the MEC boundary database, and then, according to the fourth node set, the set of candidate nodes that can deploy the MEC server, that is, the first node set, may be determined more accurately.
