Description

This disclosure relates to core network devices, application servers, communication systems, communication methods, and programs. Various application services are provided via mobile networks. Application service providers distribute computing resources, such as physical or virtual servers, across multiple locations. Application providers deploy application servers to these computing resources to provide high-quality and highly reliable application services. For example, application servers may include servers providing applications such as mail servers, video distribution servers, and web servers. To provide high-quality and highly reliable application services, providers may dynamically change the allocation of computing resources depending on their usage and other factors. The purpose of dynamically changing the allocation of computing resources is to achieve both acceptable costs and the availability of necessary computing resources. Application service providers can secure computing resources using cloud services. Cloud services offer various options, such as high-performance, high-cost computing resources, or general-purpose, low-cost computing resources. Furthermore, securing computing resources at a lower cost can be achieved through long-term contracts for high-performance resources or spot utilization of unused surplus computing resources. Additionally, reserved computing resources can be allocated to limited user groups, while other users can be provided with on-demand or spot computing resources. This can reduce the overall cost of application services. In this way, application providers aim to achieve both acceptable costs and the availability of computing resources by managing dynamic distributed computing resources, securing the necessary resources when needed and releasing them when not needed, all while considering acceptable costs. Non-Patent Document 1 discloses a process for distributing or offloading traffic in a mobile network. Non-Patent Document 1 discloses that an Application Function (AF) achieves traffic distribution using a Network Exposure Function (NEF) service. For example, the AF sends an AF request to the NEF that includes N6 Traffic Routing requirements as an Information element. N6 Traffic Routing requirements are information specifying the traffic route at N6 reference points as defined by 3GPP®. Furthermore, Non-Patent Document 2 specifies the TrafficInfluence API as an Application Programming Interface (API) related to N6 Traffic Routing requirements. The TrafficInfluence API specifies that multiple RouteToLocation attributes can be specified in the trafficRoutes attribute. Since the RouteToLocation attribute indicates the destination of traffic, specifying multiple RouteToLocation attributes enables the distribution or offloading of traffic related to a particular application service. 3GPP TS 23.501 V17.5.0 (2022-06)3GPP TS 29.522 V17.6.0 (2022-06) This is a configuration diagram of the application server related to this disclosure.This is a configuration diagram of the core network device related to this disclosure.This diagram shows the flow of communication processing performed in the application server related to this disclosure.This diagram shows the flow of communication processing performed in the core network device related to this disclosure.This is a diagram of the communication system related to this disclosure.This diagram illustrates the resource group related to this disclosure.This diagram shows the traffic offload processing flow related to this disclosure.This diagram illustrates the TrafficInfluence API related to this disclosure.This diagram illustrates the AF Request information related to this disclosure.This diagram illustrates the TrafficControlData attribute related to this disclosure.This diagram illustrates the resource group related to this disclosure.This diagram illustrates the TrafficInfluence API related to this disclosure.This diagram illustrates the AF Request information related to this disclosure.This diagram illustrates the TrafficControlData attribute related to this disclosure.This is a configuration diagram of the application server and core network device related to this disclosure.
