Abstract

The invention is directed to systems, methods and computer program products for managing handover of a terminal on a network. An exemplary method comprises: receiving sensor data associated with the terminal; receiving time data associated with the terminal; predicting a journey of the terminal based on at least one of the sensor data and the time data; generating a mobility map based on the predicted journey; and transmitting the mobility map to the network.

First claim

The invention claimed is:

1. A method for managing handover of a terminal on a wireless network, the method comprising:
receiving, by a processor device, sensor data from one or more sensors, wherein the sensor data includes at least location data and
time data associated with the terminal;
determining, by the processor device, a predicted travel route of the terminal and a predicted time for the terminal to be on the predicted travel route based on the sensor data;
generating, by the processor device, a mobility map that includes the predicted travel route of the terminal and the predicted time; and
transmitting the mobility map from the terminal to the wireless network, wherein the wireless network uses the mobility map to determine when the terminal will be in a high mobility mode that is defined by occurrence of a predetermined threshold number of handovers during a predetermined time period based on the predicted travel route from the mobility map, wherein determination of when the terminal is in a high mobility mode provides for the wireless network to manage handovers of the terminal during the high mobility mode so as to minimize an amount of control data traffic between the terminal and the wireless network.

2. The method of claim 1 , wherein the wireless network uses the mobility map to determine when the terminal will be in high mobility mode based on a number of handovers to be executed during the predicted travel route being equal to or greater than the predetermined threshold number of handovers.

3. The method of claim 1 , wherein the wireless network further uses the mobility map to determine at least one of, a timing associated with one or more handovers of the terminal during the predicted travel route, or one or more cells or base stations to which the terminal's data or voice session is handed over during the predicted travel route.

4. The method of claim 1 , wherein transmitting the mobility map comprises transmitting, from the terminal to the wireless network, a link to the mobility map.

5. The method of claim 1 , wherein transmitting the mobility map further comprises transmitting the mobility map from the terminal to a navigation server, wherein the navigation server is accessible to the wireless network.

6. The method of claim 1 , wherein in response to the wireless network determining that the terminal is in high mobility mode, assigning the terminal to a macrocell upon receiving a first handover request associated with the terminal during the predicted travel route.

7. The method of claim 1 , wherein the sensor data comprises movement data from an accelerometer, a gyro, a compass or other sensor that can provide relevant movement data.

8. The method of claim 1 , wherein the location data is received using a positioning system associated with the terminal.

9. The method of claim 1 , wherein the determining step is based further on movement history associated with sensor data acquired over time by the one or more sensors inal.

10. The method of claim 1 , wherein the mobility map further includes network coverage information and signal strength information.

11. The method of claim 1 , wherein the mobility map comprises a geographical map.

12. The method of claim 1 , wherein the terminal comprises at least one of a mobile computing device, a mobile phone, a television, a watch, or a tablet computing device.

13. The method of claim 1 , wherein the network comprises at least one base station.

14. The method of claim 1 , wherein generating further comprises generating multiple mobility maps, wherein the multiple mobility maps are differentiated based on at least one of the time data, the location data or the sensor data.

15. The method of claim 1 , wherein generating further comprises generating multiple mobility maps, wherein the multiple mobility maps are differentiated based on local or remote information.

16. The method of claim 1 , wherein use of the mobility map to determine when the terminal is in high mobility mode is triggered based on an application being executed on the terminal requiring a power level equal to or greater than a threshold power level.

17. The method of claim 1 , wherein generating further comprises generating the mobility map based on local and remote information sources.

18. An apparatus for managing handover of a terminal on a wireless network, the apparatus comprising:
a memory;
a processor in communication with the memory;
one or more sensors in communication with the processor; and
a module stored in the memory, executable by the processor, and configured to:
receive sensor data from the one or more sensors, wherein the sensor data includes at least location data and
time data associated with the terminal,
determine a predicted travel route of the terminal and a predicted time for the terminal to be on the predicted travel route based on the sensor data,
generate a mobility map that includes the predicted travel route of the terminal and the predicted time, and
transmit the mobility map from the terminal to the wireless network, wherein the wireless network uses the mobility map to determine when the terminal will be in a high mobility mode that is defined by occurrence of a predetermined threshold number of handovers during a predetermined time period based on the predicted travel route from the mobility map, wherein determination of when the terminal is in a high mobility mode provides for the wireless network to manage handovers of the terminal during the high mobility mode so as to minimize an amount of control data traffic between the terminal and the wireless network.

19. A computer program product for managing handover of a terminal on a network, the computer program product comprising:
a non-transitory computer-readable medium comprising a set of codes for causing a computer to:
receive sensor data from the one or more sensors, wherein the sensor data includes at least location data and
time data associated with the terminal;
determine a predicted travel route of the terminal and a predicted time for the terminal to be on the predicted travel route based on the sensor data;
generate a mobility map that includes the predicted travel route of the terminal and the predicted time; and
transmit the mobility map from the terminal to the wireless network, wherein the wireless network uses the mobility map to determine when the terminal will be in a high mobility mode that is defined by occurrence of a predetermined threshold number of handovers during a predetermined time period based on the predicted travel route from the mobility map, wherein determination of when the terminal is in a high mobility mode provides for the wireless network to manage handovers of the terminal during the high mobility mode so as to minimize an amount of control data traffic between the terminal and the wireless network.
