Abstract:
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: establishing an upper limit of a plurality of consecutively-increasing scanning delay periods n=[n causing a scanning operation to be performed to identify one or more available wireless communication networks in a coverage area of the communication device; if a preferred wireless network is identified to be available for communication services from the scanning operation, establishing a connection with the preferred wireless network for accessing the communication services made available in the preferred wireless network; each time the scanning operation fails to result in any connection between the communication device and a wireless network, causing the scanning operation to be repeated after delaying for a next scanning delay period of the plurality of consecutively-increasing scanning delay periods; identifying whether a predetermined battery condition of the communication device exists; and reestablishing the upper limit of the plurality of consecutively-increasing scanning delay periods n=[n
