Abstract

A new traffic offloading technique in a communication system is provided. A control apparatus of the present invention includes: a first means for managing a policy used for load balancing among a plurality of networks including a first network and a second network, wherein the first network includes a first network node that performs predetermined signal processing and the second network includes a second network node that operates a function of the first network through a virtual machine; and a second means for notifying the policy to a communication apparatus, which is capable of selecting a network node to which communication data related to a terminal is to be sent.

Claims

1. A control apparatus comprising:

a first controller that is configured to manage a policy used for load balancing among a plurality of networks including a first network and a second network, wherein the first network includes a first network node that performs predetermined signal processing and the second network includes a second network node that operates a function of the first network through a virtual machine; and

a second controller that is configured to notify the policy to a communication apparatus, which is capable of selecting a network node to which communication data related to a terminal is to be sent.

2. The control apparatus according to claim 1, wherein the second controller is configured to notify the communication apparatus of the policy, which is used for the second network to offload a load on the first network.

3. The control apparatus according to claim 1, wherein the second controller is configured to notify the communication apparatus of the policy, which is used to identify a type of the terminal to be allocated to the second network node.

4. The control apparatus according to claim 1, wherein the second controller is configured to notify the communication apparatus of the policy, which is used to identify an attribute of the terminal to be allocated to the second network node.

5. The control apparatus according to claim 1, wherein the second controller is configured to notify the communication apparatus of the policy, which is used to identify a communication type to be allocated to the second network node.

6. The control apparatus according to claim 1, wherein the second controller is configured to notify the communication apparatus of the policy, which is used for the second network node to offload a load on the first network node, wherein the second network node is operated by the virtual machine, which is dynamically constructed.

7. The control apparatus according to claim 1, wherein the second controller is configured to notify the communication apparatus of the policy, which is used for the second network node to offload a load on the first network node, wherein the second network node is operated by the virtual machine, which is dynamically constructed according to a predetermined requirement.

8. The control apparatus according to claim 1, further comprising:

a third controller that is configured to perform resource allocation to the virtual machine in the second network.

9. The control apparatus according to claim 1, further comprising:

a third controller that is configured to allocate a resource to the virtual machine, the resource corresponding to a load to be offloaded by the second network based on the policy.

10. The control apparatus according to claim 1, further comprising:

a third controller that is configured to perform resource allocation to the virtual machine responsive to a processing load on the second network.

21. A communication system including the control apparatus according to claim 1.

11. A control method comprising:

managing a policy used for load balancing among a plurality of networks including a first network and a second network, wherein the first network includes a first network node that performs predetermined signal processing and the second network includes a second network node that operates a function in the first network through a virtual machine; and

notifying the policy to a communication apparatus, which is capable of selecting a network node to which communication data related to a terminal is to be sent.

12. The control method according to claim 11, wherein the communication apparatus is notified of the policy, which is used for the second network to offload a load on the first network.

13. The control method according to claim 11, wherein the communication apparatus is notified of the policy, which is used to identify a type of the terminal to be allocated to the second network node.

14. The control method according to claim 11, wherein the communication apparatus is notified of the policy, which is used to identify an attribute of the terminal to be allocated to the second network node.

15. The control method according to claim 11, wherein the communication apparatus is notified of the policy, which is used to identify a communication type to be allocated to the second network node.

16. The control method according to claim 11, wherein the communication apparatus is notified of the policy, which is used for the second network node to offload a load on the first network node, wherein the second network node is operated by the virtual machine, which is dynamically constructed.

17. The control method according to claim 11, wherein the communication apparatus is notified the policy, which is used for the second network node to offload a load on the first network node, wherein the second network node is operated by the virtual machine, which is dynamically constructed according to a predetermined requirement.

18. The control method according to claim 11, further comprising:

performing resource allocation to the virtual machine in the second network.

19. (canceled)

20. (canceled)

22. A non-transitory recording medium storing a program comprising a set of instructions to:

manage a policy used for load balancing among a plurality of networks including a first network and a second network, wherein the first network includes a first network node that performs predetermined signal processing and the second network includes a second network node that operates a function in the first network through a virtual machine; and

notify the policy to a communication apparatus, which is capable of selecting a network node to which communication data related to a terminal is to be sent.
