Abstract
An integrated pager and cellular phone (123) includes circuitry (502, 515) that responds to receipt by the pager (122) of an incoming-call-indicative paging signal by connecting the cellular phone (121) to a battery power source (513). This activates the cellular phone, whereupon it registers with a base station (107-109) and thus becomes able to receive the incoming call. The circuitry further responds to receipt by the pager of a second paging signal by disconnecting the cellular phone from the battery power source. This allows the cellular phone to be kept in a deactivated condition and not draining battery power at times when the cellular phone is not in use, without missing incoming calls, and does so automatically, without intervention of the user of the cellular phone.
