Abstract

A wireless transmit/receive unit (WTRU) may transmit a discovery request to a first edge enabler server (EES) instance to obtain edge application server (EAS) information. The WTRU may receive a discovery response from the first EES instance. The discovery response may display a list of EAS information and/or registrar EES information for one or more EAS instances in the list of EAS information. The WTRU may select an EAS instance based on one or more of the list of EAS information or the registrar EES information for one or more EAS instances. Among the multiple EES instances, the second EES instance may be the registrar EES of the selected EAS instance.

Description

Discovery, selection, and provisioning of edge services driven by a Wireless Transceiver Unit (WTRU) using shared edge application server (EAS) information and registrar edge enabler server (EES) information This application claims the benefit of U.S. Provisional Application No. 63/466,372 filed on May 15, 2023, the full text of which is incorporated herein by reference. The edge enablement service layer of a cellular communication system may have cardinality rules that restrict an Edge Application Server (EAS) to a single Edge Enabler Server (EES). For a WTRU to discover available edge services, an EAS discovery request must be sent to the EES where the EAS is registered (e.g., a registrar EES). Discovery of a common EAS for a group of Application Clients (ACs) may require EAS discovery (e.g., by communicating with an EES other than the EAS's registrar EES). Therefore, a cellular communication system may be configured to support EAS discovery by using, for example, an EES other than the registrar EES. One or more techniques associated with the use of a non-registrar EES for discovery operations are described herein. As a first instance, the WTRU can obtain information about EAS instances available in the Edge Data Network (EDN) by sending EAS discovery requests to each EES instance within the EDN. Additionally, new use cases may require EAS information to be provided during edge service discovery or selection from different registrar EES(s). For example, the WTRU can discover and select edge services without connecting individually to all EES within the EDN. The edge enablement service layer of a cellular communication system may be used to enable edge service discovery, for example, by using an EES other than the registrar EES of the EAS that needs to be discovered. As a second instance, specific edge service discovery procedures may provide EAS information regarding discovered EAS instances registered with the EES handling the request. For example, if an EES can return EAS information from an EAS registered with another EES instance, the WTRU may not be able to determine the EES to which the EAS is registered and may not be able to indicate the selection of the EAS and Application Context Relocation (ACR) scenario from the registrar EES. A service continuity procedure failure may occur. Therefore, the edge enablement service layer of the cellular communication system may be used to enable the WTRU to acquire the registrar EES information necessary to accurately indicate the selection of the EAS and ACR scenario from the EES to which the selected EAS is registered. Alternatively, the edge enablement service layer of the cellular communication system may be used to enable the EES to accurately handle service continuity for an EAS registered with another EES.
