ABSTRACT:
A wireless terminal or other type of user terminal in a communication system is configured so as to be permitted to enter an enhanced feature access mode based at least in part on a communication of designated information between the user terminal and a corresponding switch of the system. The designated information may comprise, e.g., a feature access code associated with the enhanced feature access mode and entered by a user at the user terminal, or a pre-specified signal transmitted from the user terminal to the switch of the system. When in the enhanced feature access mode, the user terminal is provided with navigation and activation mechanisms which utilize a keypad of the user terminal in conjunction with a display of the user terminal to provide access to features of the communication system from the user terminal. For example, the navigation and activation mechanisms may each utilize disjoint subsets of a given set of keys on a terminal keypad, e.g., an otherwise conventional 12-key keypad.
