Abstract

A method and system for handling a wireless communication in a Voice over Wireless Fidelity (VoWiFi) system including a plurality of nodes is provided. The method includes detecting, by a VoWiFi controller, a wireless connection between an electronic device and a first node from among the plurality of nodes; determining, by the VoWiFi controller, a performance of each of the plurality of nodes; detecting, by the VoWiFi controller, that a first performance of the first node is less than a second performance of a second node from among the plurality of nodes; and performing, by the VoWiFi controller, a handover of the electronic device from the first node to the second node.

First claim

What is claimed is:

1. An electronic device for handling a wireless communication in a Voice over Wireless Fidelity (VoWiFi) system comprising a plurality of nodes, the electronic device comprising:
a memory;
a transceiver; and
a processor coupled to the memory and the transceiver,
wherein the processor is configured to:
detect a connection between the electronic device and a first node from among the plurality of nodes,
determine a performance of each of the plurality of nodes,
detect that a first performance of the first node is less than a second performance of a second node from among the plurality of nodes, and
perform a handover of the electronic device from the first node to the second node by transferring an internet protocol security (IPSec) tunnel from a first interface associated with the first node to a second interface associated with the second node.

2. The electronic device of claim 1 , wherein the processor is further configured to perform the handover by:
detecting (the IPSec) tunnel between the electronic device and the first interface associated with the first node; and
preserving the IPSec tunnel for a time period.

3. The electronic device of claim 2 , wherein the processor is further configured to use routing commands to transfer the IPSec tunnel from the first interface associated with the first node to the second interface associated with the second node.

4. The electronic device of claim 2 , wherein the first interface associated with the first node is bounded to the second interface associated with the second node based on a Real-simultaneous dual-band (RSDB).

5. The electronic device of claim 1 , wherein the first node is a first Wi-Fi access point and the second node is a second Wi-Fi access point.

6. The electronic device of claim 1 , wherein the processor is further configured to determine the performance of each of the plurality of nodes by:
determining a Socio VoWiFi metric for each of the plurality of nodes based on a plurality of socio parameters associated with each of the plurality of nodes; and
determining the performance of each of the plurality of nodes based on the Socio VoWiFi metric.

7. The electronic device of claim 6 , wherein the plurality of socio parameters comprises social activities, a connection status, quality parameters, and a growth poll period.

8. The electronic device of claim 7 , wherein the social activities comprise a time of user activity, and a location of user activity.

9. The electronic device of claim 1 , wherein the processor is further configured to determine the performance of each of the plurality of nodes by:
determining a Cross Layer Enhanced Handover (CLEH) metric for each of the plurality of nodes based on a plurality of CLEH parameters; and
determining the performance of each of the plurality of nodes based on the CLEH metric.

10. The electronic device of claim 9 , wherein the plurality of CLEH parameters comprises at least one of a Wi-Fi Received Signal Strength Indicator (RSSI), a Long Term Evolution (LTE Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and an Internet Protocol (IP) Multimedia Subsystem (IMS) registration state.

11. A method for handling a wireless communication in a Voice over Wireless Fidelity (VoWiFi) system comprising a plurality of nodes, the method comprising:
detecting a connection between an electronic device and a first node from among the plurality of nodes,
determining a performance of each of the plurality of nodes;
detecting that a first performance of the first node is less than a second performance of a second node from among the plurality of nodes, and
performing the handover of the electronic device from the first node to the second node by transferring an internet protocol security (IPSec) tunnel from a first interface associated with the first node to a second interface associated with the second node.

12. The method of claim 11 , wherein the performing the handover further comprises:
detecting the (IPSec) tunnel between the electronic device and the first interface associated with the first node; and
preserving the IPSec tunnel for a time period.

13. The method of claim 12 , wherein the performing the handover further comprises:
transferring the IPSec tunnel using routing commands.

14. The method of claim 12 , wherein the first interface associated with the first node is bounded to the second interface associated with the second node based on a Real-simultaneous dual-band (RSDB).

15. The method of claim 11 , further comprises:
determining a Socio VoWiFi metric for each of the plurality of nodes based on a plurality of socio parameters associated with each of the plurality of nodes; and
determining the performance of each of the plurality of nodes based on the Socio VoWiFi metric.

16. The method of claim 15 , wherein the plurality of socio parameters comprises social activities, a connection status, quality parameters, and a growth poll period.

17. The method of claim 16 , wherein the social activities comprise a time of user activity and a location of user activity.

18. The method of claim 11 , wherein the determining the performance of each of the plurality of nodes comprises:
determining a Cross Layer Enhanced Handover (CLEH) metric for each of the plurality of nodes based on a plurality of CLEH parameters; and
determining the performance of each of the plurality of nodes based on the CLEH metric.
