Among the terms used in this disclosure, terms defined in general dictionaries may be interpreted to have the same or similar meaning as the meaning they have in the context of related technology, and unless clearly defined in this disclosure, have an ideal or excessively formal meaning. It is not interpreted as In some cases, even terms defined in the present disclosure cannot be interpreted to exclude embodiments of the present disclosure.

In various embodiments of the present disclosure described below, a hardware approach method is explained as an example. However, since various embodiments of the present disclosure include technology using both hardware and software, the various embodiments of the present disclosure do not exclude software-based approaches.

Terms used in the following description refer to signals, terms referring to channels, terms referring to control information, terms referring to network entities, terms referring to data stored in network objects, and transmission and reception between objects. Terms referring to messages, terms referring to components of a device, etc. are provided as examples for convenience of explanation. Accordingly, the present disclosure is not limited to the terms described below, and other terms having equivalent technical meaning may be used.

In addition, the present disclosure describes various embodiments using terms used in some communication standards (eg, 3rd Generation Partnership Project (3GPP)), but this is only an example for explanation. Various embodiments of the present disclosure can be easily modified and applied to other communication systems.

In order to meet the increasing demand for wireless data traffic following the commercialization of the 4G (4th generation) communication system, efforts are being made to develop an improved 5G (5th generation) communication system or pre-5G communication system. For this reason, the 5G communication system or pre-5G communication system is called a Beyond 4G Network communication system or a Post LTE (long term evolution) system.

To achieve high data rates, 5G communication systems are being considered for implementation in ultra-high frequency (mmWave) bands (such as the 60 GHz band). In order to alleviate the path loss of radio waves in the ultra-high frequency band and increase the transmission distance of radio waves, the 5G communication system uses beamforming, massive array multiple input/output (massive MIMO), and full dimension multiple input/output (FD-MIMO). ), array antenna, analog beam-forming, and large scale antenna technologies are being discussed.

In addition, to improve the network of the system, the 5G communication system uses advanced small cells, advanced small cells, cloud radio access networks (cloud RAN), and ultra-dense networks. , Device to Device communication (D2D), wireless backhaul, moving network, cooperative communication, CoMP (Coordinated Multi-Points), and interference cancellation. Technology development is underway.

In addition, the 5G system uses FQAM (Hybrid FSK and QAM Modulation) and SWSC (Sliding Window Superposition Coding), which are advanced coding modulation (ACM) methods, and advanced access technologies such as FBMC (Filter Bank Multi Carrier) and NOMA. (non orthogonal multiple access), and SCMA (sparse code multiple access) are being developed.

Meanwhile, 3GPP, which is in charge of cellular mobile communication standards, has named a new core network structure as 5G core (5GC) and is standardizing it in order to evolve from the existing 4G LTE system to a 5G system.

5GC supports the following differentiated functions compared to the evolved packet core (EPC), which is the existing network core for 4G.

First, in 5GC, the network slice function is introduced. As a requirement for 5G, 5GC must support a variety of user equipment (UE) types and services. For example, enhanced mobile broadband (eMBB), ultra reliable low latency communications (URLLC), and massive machine type communications (mMTC). These terminals/services each have different requirements for the core network. For example, eMBB service requires a high data rate, and URLLC service requires high stability and low delay. One of the technologies proposed to satisfy these various service requirements is network slicing.

Network slicing is a method of creating multiple logical networks by virtualizing one physical network, and each network slice instance (NSI) can have different characteristics. Therefore, each NSI can satisfy various service requirements by having a network function (NF) suitable for its characteristics. Multiple 5G services can be efficiently supported by allocating an NSI that matches the characteristics of the service required for each terminal.

Second, 5GC can facilitate support of network virtualization paradigm through separation of mobility management function and session management function. In 4G LTE, all terminals could receive services through signaling exchange with a single core device called a mobility management entity (MME), which is responsible for registration, authentication, mobility management, and session management functions. However, in 5G, as the number of terminals increases explosively and the mobility and traffic/session characteristics that must be supported depending on the type of terminal are subdivided, when all functions are supported by a single device such as MME, expansion is required to add entities for each required function. Scalability is bound to drop. Therefore, various functions are being developed based on a structure that separates the mobility management function and session management function to improve scalability in terms of signaling load and functional/implementation complexity of the core equipment responsible for the control plane.

Meanwhile, edge computing systems are emerging recently. In an edge computing system, UE (user equipment) can receive edge computing services by establishing a data connection to an edge data network (EDN) located close to its location in order to use low-latency or broadband services. there is. These edge computing services are an edge hosting environment running on the Edge Enabler Server (EES) of a specific edge data network or an edge application server running on the edge computing platform. The service can be provided through (Edge Application Server, EAS). In other words, the UE can receive edge computing services from the edge application server (EAS) closest to the area where it is located.

The present disclosure provides a method and device for searching and obtaining an edge application server that can use the functions of an application with which the edge application server is associated when the terminal moves.

Additionally, the present disclosure provides an operation and device for notifying the validity and reuse of information about previously connected federated edge computing service-related servers when re-running an edge application server providing a federated function.

Additionally, the present disclosure provides a method of searching for a valid edge application server when an edge application server for providing a federation function is not found.

In addition, the present disclosure provides elements that allow the application enabler server to identify the edge application server providing federation functions and the services of the available federated application servers (e.g. federated EAS indicator, available EAS APIs.) and federated edge application server information ( Provides a federated context processing method to provide Edge Application Server Profile, e.g. Edge Application Server address/service area/ststus/service KPI, etc.) to the edge application server.

In addition, the present disclosure provides a method for minimizing terminal signaling to reacquire edge computing setting information and edge application information of the terminal when an update to the above information occurs.

According to an embodiment of the present disclosure, a method performed in an edge enabler server (EES) in a wireless communication system supporting edge computing includes registering the EES including a federated edge application server identifier from an edge application server (EAS). A process of receiving a request message, a process of providing federated EAS information valid for the EAS to the EAS, a process of selecting a method for the EES to provide EAS information that can use the federated EAS to the EAS, and the federation It includes the process of performing an operation based on the selected provision method so that EAS information is provided.

Additionally, according to an embodiment of the present disclosure, in a wireless communication system supporting edge computing, an edge enabler server (EES) includes a transceiver and, through the transceiver, the context of a federated edge application server that is not set in the EES. and a processor configured to receive a registration request message including, select a method for providing federated EAS information for the EAS, and perform an operation based on the selected provision method so that the EAS information is provided to the terminal.

The present invention proposes a context relocation method to continuously provide federated services of an edge application server when a terminal moves. We propose a method to search for edge application servers that provide federation functions. When there is no edge application server that provides valid federation functions within the same edge data network, we propose a method of requesting a search from another edge data network. We propose a method for an edge computing service entity to identify edge application servers that provide federation functions. We propose a method for storing and providing a list of valid federated edge application servers. This situation may occur depending on the geographically distributed deployment characteristics of the edge computing servers and the mobility of the terminal.
