Abstract

A method for enabling migration of computing information between a first edge computing device associated with a first cell in a cellular network and at least a second edge computing device associated with a second cell in the cellular network, wherein the cellular network comprises a plurality of cells, the method comprising determining the trajectory of a wireless communication device located within a first cell of the cellular network, identifying a second cell of the cellular network towards which the trajectory leads, causing allocation of resources at the second edge computing device associated with the second cell to enable migration of computing information from the first edge computing device associated with the first cell to the second edge computing device associated with the second cell.

The invention claimed is:

1. A method, performed by a computing device in a communication system, for enabling migration of computing information between a first edge computing device associated with a first cell in a cellular network and at least a second edge computing device associated with a second cell in the cellular network, wherein the cellular network comprises a plurality of cells, the method comprising:
determining a trajectory of a wireless communication device located within a first cell of a cellular network based on positioning information received from a massive Multiple-Input and Multiple-Output (MIMO) antenna operatively connected to a base station in an access network;
identifying a second cell of the cellular network towards which the trajectory leads;
causing allocation of resources at the second edge computing device associated with the second cell to enable migration of computing information from the first edge computing device associated with the first cell to the second edge computing device associated with the second cell, wherein the computing information enables the wireless communication device to operate with an application executing on the second edge computing device;
before handover is performed, migrating a first group of computing information from the first edge computing device associated with the first cell to the second edge computing device associated with the second cell, wherein the first group of computing information comprises static information; and
when the handover has been performed, migrating a second group of computing information from the first edge computing device associated with the first cell to the second edge computing device associated with the second cell, wherein the second group of computing information comprises dynamic information; and
wherein the dynamic information comprises information that changes frequently relative to the static information.

2. The method of claim 1 , wherein the method comprises determining the trajectory of the wireless communication device based on determining a beam/signal strength of the wireless communication device relative to at least one access node of the network.

3. The method of claim 1 , further comprising causing allocation of resources at at least one third edge computing device associated with at least one third cell to enable migration of computing information from the first edge computing device associated with the first cell to the at least one third edge computing device associated with the at least one third cell.

4. The method of claim 1 , wherein the allocation of resources comprises configuring computational capacity, storage capacity, connectivity, and/or radio capacity of the respective edge computing device.

wherein the dynamic information comprises information that changes frequently relative to the static information.

6. The computing device of claim 5 , wherein the instructions are such that the computing device is operative to determine the trajectory of the wireless communication device based on a beam/signal strength of the wireless communication device relative to at least one access node of the network.

7. The computing device of claim 5 , wherein the instructions are such that the computing device is operative to cause allocation of resources at at least one third edge computing device associated with at least one third cell to enable migration of computing information from the first edge computing device associated with the first cell to at least one third edge computing device associated with at least one third cell.

8. The computing device of claim 5 , wherein the allocation of resources comprises configuring computational capacity, storage capacity, connectivity, and/or radio capacity of the respective edge computing device.

9. A non-transitory computer readable recording medium storing a computer program product for controlling a computing device in a communications system for enabling migration of computing information between a first edge computing device associated with a first cell in a cellular network and at least a second edge computing device associated with a second cell in the cellular network, wherein the cellular network comprises a plurality of cells, the computer program product comprising program instructions which, when run on processing circuitry of the computing device, causes the computing device to:
