An edge configuration server, a multi-access system, a method, and a computer-readable medium are provided that make it possible to relocate an application context between different multi-access edge computing systems. An edge configuration server according to the present disclosure is a server included in a multi-access edge computing (MEC) system, and includes: a reception unit configured to receive, from a source-edge enabler server (S-EES) in the MEC system, an inquiry about a relocation target of an application context; and a transmission unit configured to transmit, to another edge configuration server (ECS) in another MEC system, an inquiry about the relocation target.
