Method, device and computer program product for managing radio states in a mobile communication device using device mobility information

摘要

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.

主权项

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.
