Method, device and computer program product for managing radio states in a mobile communication device using device mobility information
This disclosure is directed to a method, computer program product and mobile communication device configured for managing radio states in a mobile communication device using device mobility information. A mobility state is determined from the number of cell changes over a predefined period of time. If the mobility state transitions to medium or high, such as when the user is in a vehicle, a Bluetooth™ radio is enabled. If a connection to a Bluetooth™-enabled device is available, a connection is established. When the connection is disconnected, a configurable timer is started. If the timer expires without re-establishing the connection or the mobility state transitioning to medium or high, the Bluetooth™ radio is disabled to reduce power consumption. According to an embodiment, a Wi-Fi radio may then be enabled to establish a Wi-Fi connection. Various configurations of computer program products and mobile communication devices are also described.
1. A method comprising:
when a mobility state of a mobile device is at or above a first predetermined threshold, enabling a first short-range radio and establishing a first short-range radio connection;
when the first short-range radio connection is disconnected, disabling the first short-range radio after a first predetermined time period during which: the mobility state is below the first predetermined threshold; and, the first short-range radio connection is not re-established;
when the mobility state is at or above a second predetermined threshold, enabling a second short-range radio after a second predetermined time period that follows the first short-range radio being disabled; and,
when no second short-range radio connection is established during a third predetermined time period, disabling the second short-range radio.
2. The method of claim 1 , further comprising establishing the first short-range radio connection after the first short-range radio is enabled.
3. The method of claim 1 , further comprising monitoring the mobility state of the mobile device.
4. The method of claim 1 , wherein the first short-range radio comprises a Bluetooth™ radio.
5. The method of claim 1 , further comprising configuring the first predetermined time period.
6. The method of claim 1 , wherein the second short-range radio comprises a Wi-Fi radio.
7. The method of claim 1 , further comprising configuring the second predetermined time period.
8. The method of claim 1 , further comprising, when the second short-range radio connection is not established, and after the mobility state is at or above the first predetermined threshold, disabling the second short-range radio.
9. The method of claim 1 , further comprising configuring the third predetermined time period.
10. A mobile device comprising:
a processor, a first short-range radio, and, a second short-range radio, the processor configured to:
when a mobility state of a mobile device is at or above a first predetermined threshold, enable the first short-range radio and establishing a first short-range radio connection;
when the first short-range radio connection is disconnected, disable the first short-range radio after a first predetermined time period during which: the mobility state is below the first predetermined threshold; and, the first short-range radio connection is not re-established;
when the mobility state is at or above a second predetermined threshold, enable the second short-range radio after a second predetermined time period that follows the first short-range radio being disabled; and,
when no second short-range radio connection is established during a third predetermined time period, disable the second short-range radio.
11. The mobile device of claim 10 , wherein the processor is further configured to establish the first short-range radio connection after the first short-range radio is enabled.
12. The mobile device of claim 10 , wherein the processor is further configured to monitor the mobility state of the mobile device.
13. The mobile device of claim 10 , wherein the first short-range radio comprises a Bluetooth™ radio.
14. The mobile device of claim 10 , wherein the processor is further configured to configure the first predetermined time period.
15. The mobile device of claim 10 , wherein the second short-range radio comprises a Wi-Fi radio.
16. The mobile device of claim 10 , wherein the processor is further configured to configure the second predetermined time period.
17. The mobile device of claim 10 , wherein the processor is further configured to when the second short-range radio connection is not established, and after the mobility state is at or above the first predetermined threshold, disable the second short-range radio.
18. The mobile device of claim 10 , wherein the processor is further configured to configure the third predetermined time period.
19. A non-transitory computer-readable medium storing a computer program, wherein execution of the computer program is for:
when a mobility state of a mobile device is at or above a first predetermined threshold, enabling a first short-range radio and establishing a first short-range radio connection;
when the first short-range radio connection is disconnected, disabling the first short-range radio after a first predetermined time period during which: the mobility state is below the first predetermined threshold; and, the first short-range radio connection is not re-established;
when the mobility state is at or above a second predetermined threshold, enabling a second short-range radio after a second predetermined time period that follows the first short-range radio being disabled; and,
when no second short-range radio connection is established during a third predetermined time period, disabling the second short-range radio.
