Abstract

A more efficient network can be achieved using software-defined networking to configure routing tables to route data traffic to and from proper cells. User equipment address data and network device internet protocol address data can be utilized to define locators specific to a user equipment device in relation to various network devices. For instance, broadcasted network address data representative of a mobile device identifier address can be received by a first network device from the mobile device, wherein the mobile device identifier address comprises network address data related to an internet protocol address of a second network device, the first network device can determine a third network device capable of a communication with the mobile device, and the communication with the mobile device can be routed by the first network device to the third network device.

Claims

1. A method, comprising:

determining, by a software-defined network device comprising a processor, a first network device other than the software-defined network device;

based on a change in speed of a mobile device, updating, by the software-defined network device, a mobility status associated with the mobile device, wherein the updating comprises updating a first speed of the mobile device in relation to the first network device and updating a second speed of the mobile device in relation to a second network device; and

in response to the updating the mobility status and a condition associated with a distance of the mobile device to the first network device being satisfied,

prompting, by the software-defined network device, the mobile device to communicate with the second network device, and

routing, by the software-defined network device, a communication to the second network device to send to the mobile device.

2. The method of claim 1, further comprising:

receiving, by the software-defined network device, from the mobile device, broadcasted network address data representative of an identifier address of the mobile device.

3. The method of claim 2, wherein the identifier address comprises network address data related to an internet protocol address of the first network device.

4. The method of claim 1, further comprising:

based on the updating the mobility status, updating, by the software-defined network device, location data representative of a location of the mobile device.

5. The method of claim 1, further comprising:

updating, by the software-defined network device, network address data associated with the second network device.

6. The method of claim 5, wherein the updating comprises removing network address data associated with the first network device.

7. The method of claim 5, wherein the updating comprises adding location data representative of a location of the mobile device.

8. A software-defined network device, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

determining a condition related to a handoff of a communication between a first network device and a mobile device has been satisfied, wherein the condition is related to a first range of the mobile device in relation to the first network device and a second range of the mobile device in relation to a second network device;

generating first speed data associated with a first speed of the mobile device in relation to the first network device;

generating second speed data associated with a second speed of the mobile device in relation to the second network device; and

in response to the determining the condition has been satisfied and based on the first speed data, and the second speed data, terminating the communication between the first network device and the mobile device.

9. The software-defined network device of claim 8, wherein the operations further comprise:

receiving broadcasted network address data representative of a mobile device identifier address from the mobile device.

10. The software-defined network device of claim 9, wherein the mobile device identifier address comprises network address data related to a first internet protocol address of the first network device.

11. The software-defined network device of claim 10, wherein the operations further comprise:

receiving broadcasted network address data related to a second internet protocol address of the second network device.

12. The software-defined network device of claim 11, wherein the operations further comprise:

in response to the receiving the broadcasted network address data, updating the network address data related to the second network device.

13. The software-defined network device of claim 12, wherein the updating comprises adding the network address data to a data structure associated with the second network device.

14. The software-defined network device of claim 8, wherein the operations further comprise:

in response to the determining the condition has been satisfied, updating mobility status data associated with the second speed of the mobile device in relation to the second network device.

15. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a software-defined networking device, facilitate performance of operations, comprising:

receiving first speed data associated with a first speed of a mobile device in relation to a first network device;

receiving second speed data associated with a second speed, different from the first speed, of the mobile device in relation to a second network device;

generating a communication transfer condition associated with range data representative of a distance between the mobile device, the first network device, and the second network device; and

in response to the receiving the first speed data, the second speed data, and the communication transfer condition being determined to have been satisfied, initiating a first communication between the second network device and the mobile device, and terminating a second communication between the mobile device and the first network device.

16. The non-transitory machine-readable medium of claim 15, wherein the operations further comprise:

updating mobile device address data associated with the first communication between the second network device and the mobile device.

17. The non-transitory machine-readable medium of claim 16, wherein the updating comprises updating mobile device location data with the range data of the mobile device.

18. The non-transitory machine-readable medium of claim 17, wherein the operations further comprise:

receiving first broadcasted network address data representative of a mobile device identifier address from the mobile device.

19. The non-transitory machine-readable medium of claim 15, wherein a mobile device identifier address associated with the mobile device comprises network address data related to a first internet protocol address of the first network device.

20. The non-transitory machine-readable medium of claim 19, wherein the operations further comprise:

in response to the communication transfer condition being determined to have been satisfied, deleting the network address data related to the first internet protocol address of the first network device.
