US 12,531,933 B2 · Edge application server relocation

Abstract

Methods and apparatuses for reducing application instantiation delay and downtime are described herein. A method may comprise relocating an application function from a source Edge Data Network (EDN) component to a target EDN component. The method may comprise receiving an indication, and/or determining, based on at least one of a user mobility, resource optimization requirement, key performance indicator (KPI), or a failed relocation attempt, to relocate the application function. The method may further comprise performing a Protocol Data Unit (PDU) session establishment procedure toward the target EDN component. The method may further comprise determining, based on one or more received parameters for edge usage and capabilities, to relocate the application function. The method may further comprise sending, to a European Telecommunications Standards Institute (ETSI) Multi-access Edge Computing (MEC) orchestrator, an indication that the application function will be relocated. The application function may be a User Plane Function (UPF).

Dependent claims

A method performed by a wireless transmit receive unit (WTRU) for transferring a communication session between a source edge data network (EDN), including a source edge application server (EAS) and a source edge enabler server (EES), and a target EDN including a target EAS and a target EES, the method comprising:

communicating over a first connection, using a first protocol data unit (PDU) session, with the source EDN;
receiving notification information at the WTRU indicating:
an upcoming EAS relocation, a target EES profile, and a target EAS profile, wherein the notification information includes a notification to establish a connection to the target EDN;
receiving an indication of a time period to maintain the first connection with the source EDN;
obtaining connectivity information for the target EDN using the target EES profile and the target EAS profile;
initiating a transfer of the communication session to the target EAS using the connectivity information to establish a second connection, using a second PDU session, with the target EDN;
and maintaining the first connection with the source EDN at least until the second connection is established or until expiration of the time period.
