Method and system for adjusting a measurement cycle in a wireless receiver
View Patent ↗Methods and systems for measuring wireless signals in a wireless receiver are described. The method includes designating a measurement cycle frequency for the wireless receiver at a nominal frequency. A determination that a motion change event has occurred can be determined based on the detection of a transition between base stations in a wireless communications network. In response to the motion change event, the measurement cycle frequency can be adjusted according to various aspects of the disclosure.
1. A method of measuring a wireless signal in a wireless receiver, comprising:
designating a measurement cycle frequency for the wireless receiver at a nominal frequency;
determining that a motion change event has occurred to the wireless receiver based on detecting a transition between base stations of a wireless communications network; and
adjusting the measurement cycle frequency in response to the motion change event.
2. The method of claim 1 , further comprising determining that the motion change event is complete.
3. The method of claim 2 , further comprising resetting the measurement cycle frequency to the nominal frequency in response to determining that the motion change event is complete.
4. The method of claim 2 , wherein the motion change event is determined to be complete after a predetermined amount of time has elapsed.
5. The method of claim 2 , wherein the motion change event is determined to be complete after a predetermined time has elapsed without the occurrence of another motion change event.
6. The method of claim 1 , wherein the motion change event comprises a change in velocity or a change in direction.
7. The method of claim 1 , further comprising adjusting the measurement cycle frequency from a current frequency to a new frequency in response to detecting the occurrence of a route critical event.
8. The method of claim 7 , wherein the current frequency is different from the nominal frequency.
9. The method of claim 7 , further comprising adjusting the measurement cycle frequency from the new frequency back to the current frequency in response to determining that the route critical event is complete.
10. The method of claim 9 , wherein the route critical event is complete after a predetermined time period has elapsed or when the wireless receiver is outside of a route critical location by a threshold distance.
11. A wireless receiver device, comprising:
a receiver;
a wireless transceiver;
a memory; and
a processor configured to:
designate a measurement cycle frequency for the wireless receiver at a nominal frequency;
determine that a motion change event has occurred to the wireless receiver based on detecting a transition between base stations of a wireless communications network; and
adjust the measurement cycle frequency in response to the motion change event.
12. The wireless receiver device of claim 11 , wherein the processor is further configured to determine that the motion change event is complete.
13. The wireless receiver device of claim 12 , wherein the processor is further configured to reset the measurement cycle frequency to the nominal frequency in response to determining that the motion change event is complete.
14. The wireless receiver device of claim 12 , wherein the processor is configured to determine that the motion change event is complete after a predetermined amount of time has elapsed.
15. The wireless receiver device of claim 12 , wherein the processor is configured to determine that the motion change event is complete after a predetermined time has elapsed without the occurrence of another motion change event.
16. The wireless receiver device of claim 11 , wherein the motion change event comprises a change in velocity or a change in direction.
17. The wireless receiver device of claim 11 , wherein the processor is further configured to adjust the measurement cycle frequency from a current frequency to a new frequency in response to detecting the occurrence of a route critical event.
18. The wireless receiver device of claim 17 , wherein the current frequency is different from the nominal frequency.
19. The wireless receiver device of claim 17 , wherein the processor is further configured to adjust the measurement cycle frequency from the new frequency back to the current frequency in response to determining that the route critical event is complete.
20. The wireless receiver device of claim 19 , wherein the processor is configured to determine that the route critical event is complete after a predetermined time period has elapsed or when the wireless receiver is outside of a route critical location by a threshold distance.
