Abstract

Embodiments for network virtualization of user equipment (UE) in a wireless communication network. A trigger may be received from a user equipment (UE) indicating potential UE mobility away from a remote virtual machine (VM) instance on a host server collocated on an eNodeB in the wireless communication network. One or more identifiers (ID) of one or more potential host servers collocated on one or more alternative eNodeBs may be determined for receiving the UE. VM replication may be provided to the one or more potential host servers to enable continuation of the remote VM instance.

First claim

The invention claimed is:

1. A method for network virtualization of user equipment (UE) in a wireless communication network, comprising:
receiving a trigger from a user equipment (UE) indicating potential UE mobility away from a remote virtual machine (VM) instance on a host server in the wireless communication network;
determining one or more identifiers (ID) of potential host servers for receiving the UE; wherein the one or more potential host servers for receiving the UE are predicted prior to receiving a signal from the UE indicating which of the one or more potential host servers is to receive the UE;
providing VM replication to the one or more potential host servers, according to the prediction, to enable continuation of the remote VM instance; and
performing the VM replication on the one or more potential host servers in conjunction with a handover operation of the UE from an eNodeB to an alternative eNodeB; wherein the VM replication is initiated to each of the one or more potential host servers, irrespective of whether the one or more potential host servers includes a plurality of the potential host servers, prior to the UE commencing the handover operation from the eNodeB to the alternative eNodeB.

2. The method of claim 1 , further including predicting the UE mobility based on historical mobility patterns from the host server to the one or more potential host servers.

3. The method of claim 1 , further including predicting the UE mobility based on handover information from the eNodeB to the alternative eNodeB.

4. The method of claim 1 , further including ordering the one or more potential host servers according to a ranking for receiving the UE.

5. The method of claim 1 , further including collecting historical mobility patterns of the UE from one or more cloud storage systems.

6. The method of claim 1 , wherein each host server in the wireless communication network is an edge server collocated at the eNodeB.

7. A system for network virtualization of user equipment (UE) in a wireless communication network, comprising:
one or more computers with executable instructions that when executed cause the system to:
receive a trigger from a user equipment (UE) indicating potential UE mobility away from a remote virtual machine (VM) instance on a host server in the wireless communication network;
determine one or more identifiers (ID) of potential host servers for receiving the UE; wherein the one or more potential host servers for receiving the UE are predicted prior to receiving a signal from the UE indicating which of the one or more potential host servers is to receive the UE;
provide VM replication to the one or more potential host servers, according to the prediction, to enable continuation of the remote VM instance; and
perform the VM replication on the one or more potential host servers in conjunction with a handover operation of the UE from an eNodeB to an alternative eNodeB; wherein the VM replication is initiated to each of the one or more potential host servers, irrespective of whether the one or more potential host servers includes a plurality of the potential host servers, prior to the UE commencing the handover operation from the eNodeB to the alternative eNodeB.

8. The system of claim 7 , wherein the executable instructions further predict the UE mobility based on historical mobility patterns from the host server to the one or more potential host servers.

9. The system of claim 7 , wherein the executable instructions further predict the UE mobility based on handover information from the eNodeB to the alternative eNodeB.

10. The system of claim 7 , wherein the executable instructions further order the one or more potential host servers according to a ranking for receiving the UE.

11. The system of claim 7 , wherein the executable instructions further collect historical mobility patterns of the UE from one or more cloud storage systems.

12. The system of claim 7 , wherein each host server in the wireless communication network is an edge server collocated at the eNodeB.

13. A computer program product for, by a processor, network virtualization of user equipment (UE) in a wireless communication network, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
an executable portion that receives a trigger from a user equipment (UE) indicating potential UE mobility away from a remote virtual machine (VM) instance on a host server in the wireless communication network;
an executable portion that determines one or more identifiers (ID) of potential host servers for receiving the UE; wherein the one or more potential host servers for receiving the UE are predicted prior to receiving a signal from the UE indicating which of the one or more potential host servers is to receive the UE;
an executable portion that provides VM replication to the one or more potential host servers, according to the prediction, to enable continuation of the remote VM instance; and
an executable portion that performs the VM replication on the one or more potential host servers in conjunction with a handover operation of the UE from an eNodeB to an alternative eNodeB; wherein the VM replication is initiated to each of the one or more potential host servers, irrespective of whether the one or more potential host servers includes a plurality of the potential host servers, prior to the UE commencing the handover operation from the eNodeB to the alternative eNodeB.

14. The computer program product of claim 13 , further including an executable portion that predicts the UE mobility based on historical mobility patterns from the host server to the one or more potential host servers, wherein each host server in the wireless communication network is an edge server collocated at the eNodeB.

15. The computer program product of claim 13 , further including an executable portion that predicts the UE mobility based on handover information from the eNodeB to the alternative eNodeB.

16. The computer program product of claim 13 , further including an executable portion that orders the one or more potential host servers according to a ranking for receiving the UE.

17. The computer program product of claim 13 , further including an executable portion that collects historical mobility patterns of the UE from one or more cloud storage systems.
