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 3^rd 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.

transmitting, by the ECM, a second EC-RAN VM control command Ack message, indicating that the VM instance has started, to the ECMC, thereby the ECMC changes the status of the VM instance to a start status.

7. The method of claim 4, further comprising:

transmitting, by the ECM, to the VM host, an ECM command message indicating that the ECM commands to start the VM instance, after receiving the EC-RAN VM control command message from the ECMC; and

receiving, by the ECM, an ECM command Ack message as a response message to the ECM command message from the VM host.

8. A method for managing a virtual machine (VM) by a VM host in a mobile communication system, the method comprising:

performing, by the VM host, a preparation operation for starting a VM instance based on the preparation operation information, after receiving the first ECM command message; and

transmitting, by the VM host, a first ECM command Ack message, as a response message to the first ECM command message, to the ECM, after performing the preparation operation for starting the VM instance,

receiving a second ECM command message, which the ECM transmits according to a reception of an edge cloud-radio access network (EC-RAN) VM control command message, which comprises a VM instance identifier (ID), an EC-RAN ID, and a start code, from an edge cloud management controller (ECMC), after transmitting the first ECM command Ack message; and

transmitting a second EMC command Ack message, as a response message to the second ECM command message, to the ECM,

wherein the preparation operation information includes at least one of central processing unit (CPU) type information, memory size information, disk volume information, and operating system type information, related to the VM instance.

9. The method of claim 8, further comprising:

starting the VM instance after receiving the second ECM command message.
