ABSTRACT:
A selective call receiving device (10) such as a pager is controlled to dynamically change a base frame assigned to the device and subsequent control frames derived therefrom. The time that the device is operative to look for its address in a received signal can thus be dynamically changed to improve the efficiencies of a mixed systems environment without substantially reducing the battery life of the selective call receiving device (10). In two embodiments of the invention a new base frame for the device is derived from an originally assigned base frame that is stored in the selective call receiving device. In another embodiment, a new base frame for the device is derived from the device's address along with frame management information that is received by the selective call receiving device.
