Abstract

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.

Claims

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.
