Methods and apparatus for reducing power consumption during network scanning operations with adverse battery conditions
First Claim
1. A method for use by a communication device in scanning to establish a connection with a wireless communication network for communications, the method comprising the acts of:
- causing a scanning operation to be performed to identify one or more available wireless communication networks in a geographic area of the communication device;
each time the scanning operation fails to result in identifying a wireless network to be available for connection with the communication device, causing the scanning operation to be repeated after delaying for a next scanning delay period of a plurality of consecutively-increasing scanning delay periods n=[n1, n2, . . . , M] wherein M is set as an upper limit;
in response to identifying a first predetermined battery condition of the communication device;
adding a first new upper limit N to the plurality of consecutively-increasing scanning delay periods n=[n1, n2, . . . , M, N], wherein N is the first new upper limit such that N>
M; and
in response to identifying a second predetermined battery condition of the communication device;
adding a second new upper limit to the plurality of consecutively-increasing scanning delay periods n=[n1, n2, . . . , M, N, P], wherein P is the second new upper limit such that P>
N>
M.

Abstract
In a mobile communication device, a scanning operation is performed with use of a wireless transceiver to identify one or more available wireless communication networks in a given geographic area. Each time the scanning operation fails to result in identifying a wireless network to be available for connection with the communication device, the scanning operation is repeated after delaying for a next scanning delay period of a plurality of consecutively-increasing scanning delay periods n=[n1, n2, . . . , M], wherein M is set as an upper limit. In response to identifying a first predetermined battery condition of the communication device, a first new upper limit N is added to the plurality of consecutively-increasing scanning delay periods n=[n1, n2, . . . , M, N], wherein N is the first new upper limit such that N>M. Further, in response to identifying a second predetermined battery condition of the communication device, a second new upper limit is added to the plurality of consecutively-increasing scanning delay periods n=[n1, n2, . . . , M, N, P], wherein P is the second new upper limit such that P>N>M. Advantageously, power consumption is reduced during adverse battery conditions of the mobile device.
