Abstract

Methods, systems, and apparatuses for device routing management are disclosed. A client device of a wireless network may roam from a first access point to a second access point of the wireless network. The second access point, or the client device itself, may send a network message indicating the client device is currently being served by the second access point. The message may cause a network mapping stored at the first access point and/or at each device associated with the wireless network to be updated to indicate the client device is associated with the second access point, thereby enabling proper routing of network traffic to the client device via the second access point.

Claims (54)

1. A method comprising:

determining, by a network device, that a portion of network traffic comprises voice call data;

determining, by the network device, that a user device associated with the voice call data is no longer communicating with a first access point of a plurality of access points; and

sending, by the network device, based on the portion of network traffic being voice call data, a message to the plurality of access points, wherein the message indicates the user device is no longer communicating with the first access point.

2. The method of claim 1 , wherein determining that the user device is no longer communicating with the first access point comprises: determining, based on a time-to-live element of a network mapping table, that an amount of time indicated by the time-to-live element has elapsed, wherein the time-to-live element and the amount of time are associated with a voice call protocol.

3. The method of claim 1 , further comprising: determining that the user device has associated with a second access point of the plurality of access points, wherein the message comprises a network mapping between an identifier of the user device and an identifier of the second access point.

4. The method of claim 1 , further comprising: determining that the user device has associated with a second access point of the plurality of access points, wherein the message causes each access point of the plurality of access points to update a network mapping table to indicate the user device has associated with the second access point.

5. The method of claim 1 , wherein determining that the portion of network traffic comprises voice call data comprises:

determining, based on at least one of:

a size of a packet associated with the portion of network traffic,

a protocol type associated with the portion of network traffic,

a frequency of receipt of packets associated with the protocol type, or

a destination of the packet associated with the portion of network traffic, that the portion of network traffic comprises voice call data.

6. The method of claim 1 , further comprising:

receiving, from a second access point of the plurality of access points, an indication that the user device has associated with the second access point of the plurality of access points; and

sending, via the second access point, based on the indication, further voice call data to the user device.

7. The method of claim 6 , wherein sending the further voice call data to the user device comprises:

receiving further voice call data; and

causing, based on the indication, the second access point to send the further voice call data to the user device.

8. A method comprising:

determining, by a first device of a plurality of devices, that a portion of network traffic associated with a user device and at least one device of the plurality of devices comprises voice call data;

determining that the user device is no longer communicating with the at least one device; and

sending, based on the portion of network traffic being voice call data, a message to the plurality of devices, wherein the message indicates the user device is no longer communicating with the at least one device.

9. The method of claim 8 , wherein:

the at least one device comprises the first device, and wherein the first device comprises a gateway device; or

the at least one device comprises a second device of the plurality of devices, and wherein the second device comprises an access point.

10. The method of claim 8 , wherein determining that the user device is no longer communicating with the at least one device comprises:

determining, by a gateway device, that the user device is no longer communicating with the at least one device; or

determining, by a second device of the plurality of devices, that the user device is no longer communicating with the at least one device, wherein the second device comprises an access point.

11. The method of claim 8 , wherein determining that the user device is no longer communicating with the at least one device comprises: determining, based on a time-to-live element of a network mapping table, that an amount of time indicated by the time-to-live element has elapsed, wherein the time-to-live element and the amount of time are associated with a voice call protocol.

12. The method of claim 8 , further comprising: determining that the user device has associated with a second device of the plurality of devices, wherein the message comprises a network mapping between an identifier of the user device and an identifier of the second device.

13. The method of claim 8 , further comprising: determining that the user device has associated with a second device of the plurality of devices, wherein the message causes each device of the plurality of devices to update a network mapping table to indicate the user device has associated with the second device.

14. The method of claim 8 , wherein determining that the portion of network traffic comprises voice call data comprises:

determining, based on at least one of:

a size of a packet associated with the portion of network traffic,

a protocol type associated with the portion of network traffic,

a frequency of receipt of packets associated with the protocol type, or

a destination of the packet associated with the portion of network traffic, that the portion of network traffic comprises voice call data.

15. A method comprising:

determining, by a first device of a plurality of devices, that a portion of network traffic at the first device comprises voice call data associated with a user device;

determining that the user device is no longer communicating with the first device; and

sending, based on the user device no longer communicating with the first device, a message to at least one device of the plurality of devices, wherein the message causes the at least one device to update a network mapping associated with the user device and the voice call data.

16. The method of claim 15 , wherein the first device comprises an access point, and wherein the at least one device comprises at least one access point.

17. The method of claim 15 , wherein the network mapping comprises an identifier of the user device and an identifier of an access point, and wherein the plurality of devices comprises the access point.

18. The method of claim 15 , wherein determining that the user device is no longer communicating with the first device comprises:

determining, by a gateway device, that the user device is no longer communicating with the first device; or

determining, by a second device of the plurality of devices, that the user device is no longer communicating with the first device, wherein the second device comprises an access point.

19. The method of claim 15 , wherein determining that the user device is no longer communicating with the first device comprises: determining, based on a time-to-live element of a network mapping table, that an amount of time indicated by the time-to-live element has elapsed, wherein the time-to-live element and the amount of time are associated with a voice call protocol.

20. The method of claim 15 , wherein determining that the portion of network traffic comprises voice call data comprises:

determining, based on at least one of:

a size of a packet associated with the portion of network traffic,

a protocol type associated with the portion of network traffic,

a frequency of receipt of packets associated with the protocol type, or

a destination of the packet associated with the portion of network traffic, that the portion of network traffic comprises voice call data.
