Abstract: Methods and apparatus are provided for managing a Virtual Machine (VM) in a mobile communication system. Upon receiving a VM provisioning request message from a 3rd party entity, an Edge Cloud-Radio Access Network (EC-RAN) VM control command message, indicating that the Edge Cloud Management Controller (ECMC) commands a VM provisioning, is transmitted to an Edge Cloud Manager (ECM). An EC-RAN VM control command Ack message is received, including information indicating whether a VM host, which the EC-RAN VM control command message targets, accepts or rejects the EC-RAN VM control command message, and including a VM instance ID allocated to the VM host. A VM instance corresponding to the VM instance ID is registered and a status of the VM instance is set as an allocation status, after the EC-RAN VM control command Ack message is received from the ECM.
