Cross radio access technology handoff using caching
View Patent ↗Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments for handing off wireless communication. The apparatus comprises an antenna configured to receive data from a first access point; a cache configured to store the data; and a controller configured to predict when the transceiver will hand off a connection from the first access point to a second access point and request a burst of data from the first access point to supplement the data in the cache in preparation for the hand off.
1. A User Equipment (UE), comprising:
an antenna configured to receive data from a first access point;
a cache that stores the data; and
a controller configured to predict if the UE will undergo a connection handoff from the first access point to a second access point, and to request, responsive to predicting that the UE will undergo the connection handoff, a burst of data from the first access point to supplement the data in the cache in preparation for the connection handoff,
wherein the antenna is further configured to transmit a request for the burst of data to the first access point, and to receive the burst of data from the first access point in response to transmitting the request.
2. The UE of claim 1 , wherein the prediction is based on motion information of the UE.
3. The UE of claim 1 , wherein the prediction is based on a signal strength from the first access point.
4. The UE of claim 1 , wherein the prediction is based on a signal strength from the second access point.
5. The UE of claim 1 , wherein the controller is further configured to identify the second access point while the UE uses the data in the cache.
6. The UE of claim 5 , wherein the controller is configured to identify the second access point based on cost, data rate, Quality of Service (QoS), or a combination thereof.
7. The UE of claim 1 , wherein the controller is further configured to request an increase in a cache size in preparation for the connection handoff.
8. The UE of claim 1 , wherein the controller is further configured to request the burst of data to maintain a Quality of Service (QoS) for an application running on the UE during the connection handoff.
9. A User Equipment (UE), comprising:
an antenna configured to receive data from a first access point;
a cache that stores the data; and
a controller configured to predict if the UE will undergo a connection handoff from the first access point to a second access point, and to request, responsive to predicting that the UE will undergo the connection handoff, a burst of data from the first access point to supplement the data in the cache in preparation for the connection handoff,
wherein the antenna is further configured to transmit a request for the burst of data to the first access point, and to receive the burst of data from the first access point in response to transmitting the request, and
wherein the prediction is based on the UE approaching a dead zone.
10. A method performed by a User Equipment (UE) for handing off wireless communication, comprising:
predicting a connection handoff of the UE from a first network element to a second network element;
responsive to predicting the connection handoff, transmitting a request for a burst of data from a network;
receiving the requested burst of data in response to transmitting the request;
caching the requested burst of data; and
performing the connection handoff from the first network element to the second network element.
11. The method of claim 10 , further comprising requesting the burst of data from the first network element.
12. The method of claim 10 , wherein the prediction is based on motion information of the UE.
13. The method of claim 10 , wherein the prediction is based on a signal strength of the first network element.
14. The method of claim 10 , wherein the prediction is based on a signal strength of the second network element.
15. The method of claim 10 , further comprising identifying the second network element based on a cost, a data rate, a Quality of Service, or a combination thereof.
16. The method of claim 10 , where the prediction is based on the UE approaching a dead zone.
17. The method of claim 10 , further comprising using the burst of data to maintain a Quality of Service (QoS) of an application running on the UE while the connection handoff occurs.
