Methods and apparatus for use in controlling scanning operations or a scan rate based on call appointments or reminders are disclosed. In one illustrative example, one or more processors of a mobile communication device are operative to identify whether a call appointment or reminder for a communication session to be established during a current time period is stored in the memory, and determine a scan rate for scanning operations of the wireless transceiver which varies based on whether the call appointment or reminder for the communication session to be established is identified. If the call appointment or reminder for the communication session to be established is identified, then the scan rate may be determined to be a first scan rate; otherwise the scan rate may be determined to be a second scan rate that is less than the first rate. The scan rate may further be determined to vary based on a duration of time over which repeated scanning operations fail to identify a suitable wireless communication network for communication (e.g. as the duration of time increases, the scan rate decreases). Thus, scanning operations and/or the scan rate is preferably determined based on different items which include any stored upcoming appointments requiring wireless service, previous call attempts or call reminders, as well as the time period over which scanning has been unsuccessful. In a simpler embodiment, a scanning operation is triggered based on identifying an imminent appointment or reminder regardless of the existing scan rate which is otherwise left unchanged. Advantageously, scanning procedures are performed so as to reduce power consumption in the mobile communication device without compromising calling ability.
