A system and method for a communication apparatus to provide advanced features such as communication channel mobility, billing options for communication charges (for instance reverse billing), and definable accessibility controls. A subscriber apparatus (for instance a wireless communication apparatus) includes pager (such as a page phone) or radiotelephone functions. A caller calls the subscriber apparatus. The caller gains two-way communication with the subscriber apparatus. The subscriber apparatus may include a radio frequency power level monitor to control movement of a communication channel of the subscriber apparatus from a first communication system (for instance a regular cellular system) to a second communication system (for instance a local loop). The billing options include reversing communication charges (for instance from a subscriber to a calling party), listening to advertisements to reduce communication charges, or splitting communication charges (for instance between a subscriber and a calling party).
