Predictive scanning and handover
Systems and methods for predictive scanning and handover are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: receive context information; predict a loss of a first wireless connection based upon the context information; in response to the prediction, start scanning for a second wireless connection while maintaining the first wireless connection; and switch to the second wireless connection prior to losing the first wireless connection.
1. An Information Handling System (IHS), comprising:
a processor; and
a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to:
receive context information comprising at least one of an IHS posture, a bag state, and user presence information;
predict a loss of a first wireless connection based upon a first threshold distance or time associated with a first instance of the context information or a second threshold distance or time associated with a second instance of the context information, wherein the first instance is different than the second instance, and wherein the first threshold distance or time is different than the second threshold distance or time;
in response to the prediction, start scanning for a second wireless connection while maintaining the first wireless connection; and
switch to the second wireless connection prior to losing the first wireless connection.
2. The IHS of claim 1 , wherein the IHS comprises at least one of a mobile device, a laptop computer, or a tablet computer.
3. The IHS of claim 1 , wherein the first wireless connection comprises a WiFi connection, and wherein the second wireless connection comprises a cellular connection.
4. The IHS of claim 1 , wherein the context information comprises a Received Signal Strength Indicator (RSSI) indication.
5. The IHS of claim 1 , wherein the context information comprises a Time-of-Flight (ToF) indication.
6. The IHS of claim 1 , wherein to predict the loss, the program instructions, upon execution, further cause the IHS to determine that the IHS is moving toward a dead zone with respect to the first wireless connection using the context information.
7. The IHS of claim 6 , wherein to determine that the IHS is moving toward the dead zone, the program instructions, upon execution, further cause the IHS to compare a current behavior of a user of the IHS with a historical behavior of the user.
8. The IHS of claim 1 , wherein the IHS posture comprises at least one of a tablet posture, a laptop posture, a book posture, a tent posture, a display posture, or a closed posture.
9. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to predict the loss of the first wireless connection based upon a third threshold distance or time associated with a third instance of the context information, wherein the third instance is different than the first and second instance, and wherein the third threshold distance or time is different than the first and second threshold distance or time.
10. The IHS of claim 9 , wherein the context information comprises the presence information, and wherein the first threshold distance comprises a near-field distance, the second threshold distance comprises a mid-field distance, and the third threshold distance comprises a far-field distance.
11. The IHS of claim 1 , wherein the bag state comprises an indication of whether the IHS is inside or outside of a bag, and wherein the first threshold distance or time is associated with the IHS being inside the bag, and the second threshold distance or time is associated with the IHS being outside the bag.
12. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to:
receive additional context information;
predict a detection of the first wireless connection based upon the additional context information;
in response to the prediction, start to scan for the first wireless connection while maintaining the second wireless connection; and
switch to the first wireless connection prior to dropping the second wireless connection.
13. The IHS of claim 12 , wherein to predict the detection of the first wireless connection, the program instructions, upon execution, further cause the IHS to determine that the IHS is moving toward a live zone with respect to the first wireless connection using the additional context information.
14. The IHS of claim 13 , wherein to determine that the IHS is moving toward the live zone, the program instructions, upon execution, further cause the IHS to compare the current behavior of a user of the IHS with the historical behavior of the user.
15. The IHS of claim 12 , wherein to predict the detection of the first wireless connection, the program instructions, upon execution, further cause the IHS to determine that the IHS is within another threshold distance or time from the live zone based upon the comparison.
16. The IHS of claim 15 , wherein the program instructions, upon execution, further cause the IHS to predict the detection of the first wireless connection based upon the other threshold distance or time.
17. The IHS of claim 16 , wherein the additional context information comprises the presence information, and wherein the other threshold distance comprises at least one of a near-field distance, a mid-field distance, and a far-field distance.
18. The IHS of claim 16 , wherein the bag state comprises an indication of whether the IHS is inside or outside of a bag, and wherein the other threshold distance or time is associated with whether the IHS is inside or outside the bag.
19. A memory device having program instructions stored thereon that, upon execution by an Information Handling System (IHS), cause the IHS to:
receive context information comprising at least one of an IHS posture, a bag state, and user presence information;
predict a loss of a first wireless connection based upon a first threshold distance or time associated with a first instance of the context information or a second threshold distance or time associated with a second instance of the context information, wherein the first instance is different than the second instance, and wherein the first threshold distance or time is different than the second threshold distance or time; and
in response to the prediction, start to scan for a second wireless connection.
20. A method, comprising:
receiving context information comprising at least one of an IHS posture, a bag state, and user presence information;
predicting a loss of a first wireless connection based upon a first threshold distance or time associated with a first instance of the context information or a second threshold distance or time associated with a second instance of the context information, wherein the first instance is different than the second instance, and wherein the first threshold distance or time is different than the second threshold distance or time; and
in response to the prediction, starting to scan for a second wireless connection.
