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.

Claims

1. A method of providing enhanced feature access in a display-based mobile wireless user terminal of a communication system, the method comprising the steps of:

configuring the mobile wireless user terminal so as to permit the user terminal 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; and

providing navigation and activation mechanisms within the user terminal as part of the enhanced feature access mode, the navigation and activation mechanisms utilizing a keypad of the user terminal in conjunction with a display of the user terminal to provide access to features of the communication system not otherwise accessible utilizing the keypad, the keypad comprising a plurality of numeric keys and a plurality of non-numeric keys and being utilizable in entering a telephone number to be dialed.

2. The method of claim 1 wherein the user terminal comprises a wireless terminal.

3. The method of claim 1 wherein the designated information comprises a feature access code associated with the enhanced feature access mode and entered by a user at the user terminal.

4. The method of claim 1 wherein the designation information comprises a pre-specified signal transmitted from the user terminal to the switch of the system.

5. The method of claim 1 wherein the navigation mechanism uses a first subset of the keys of the keypad and the activation mechanism uses a second subset of the keys of the keypad, the first and second subsets being disjoint subsets.

6. The method of claim 1 wherein the activation mechanism comprises a single key the activation which is operative to activate a feature currently displayed on the display of the user terminal.

7. The method of claim 1 wherein the keypad comprises a 12-key keypad including keys for digits “

1”

through “

9”

, a “

*”

key and a “

#”

key.

8. The method of claim 7 wherein the “

*”

key and the “

#”

key are each used for one of forward or reverse scrolling through a set of available features.

9. The method of claim 7 wherein the “

1”

through “

9”

keys are used for selection of particular sub-features associated with a given currently-displayed feature.

10. The method of claim 7 wherein the “

0”

key is used for activation of a given currently-displayed feature.

11. The method of claim 1 wherein the enhanced feature access mode is exited based at least in part on detection of designated activity at the user terminal.

12. The method of claim 1 wherein the enhanced feature access mode is temporarily disabled if a particular feature activated using the activation mechanism utilizes a display mode other than that associated with the enhanced feature access mode.

13. The method of claim 12 wherein the enhanced feature access mode is subsequently re-enabled when the particular activated feature is completed or the particular activated feature is otherwise no longer activated.

14. An apparatus comprising:

a display-based mobile wireless user terminal of a communication system, the mobile wireless user terminal being operative 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 enhanced feature access mode having navigation and activation mechanisms associated therewith, the navigation and activation mechanisms utilizing a keypad of the user terminal in conjunction with a display of the user terminal to provide access to features of the communication system not otherwise accessible utilizing the keypad, the keypad comprising a plurality of numeric keys and a plurality of non-numeric keys and being utilizable in entering a telephone number to be dialed.

15. The apparatus of claim 14 wherein the user terminal comprises a wireless terminal.

16. The apparatus of claim 14 wherein the designated information comprises a feature access code associated with the enhanced feature access mode and entered by a user at the user terminal.

17. The apparatus of claim 14 wherein the designation information comprises a pre-specified signal transmitted from the user terminal to the switch of the system.

18. The apparatus of claim 14 wherein the navigation mechanism uses a first subset of the keys of the keypad and the activation mechanism uses a second subset of the keys of the keypad, the first and second subsets being disjoint subsets.

19. The apparatus of claim 14 wherein the activation mechanism comprises a single key the activation of which is operative to activate a feature currently displayed on the display of the user terminal.

20. The apparatus of claim 14 wherein the keypad comprises a 12-key keypad including keys for digits “

1”

through “

9”

, a “

*”

key and a “

#”

key.

21. The apparatus of claim 20 wherein the “

*”

key and the “

#”

key are each used for one of forward or reverse scrolling through a set of available features.

22. The apparatus of claim 20 wherein the “

1”

through “

9”

keys are used for selection of particular sub-features associated with a given currently-displayed feature.

23. The apparatus of claim 20 wherein the “

0”

key is used for activation of a given currently-displayed feature.

24. The apparatus of claim 14 wherein the enhanced feature access mode is exited based at least in part on detection of designated activity at the user terminal.

25. The apparatus of claim 14 wherein the enhanced feature access mode is temporarily disabled if a particular feature activated using the activation mechanism utilizes a display mode other than that associated with the enhanced feature access mode.

26. The apparatus of claim 25 wherein the enhanced feature access mode is subsequently re-enabled when the particular activated feature is completed or the particular activated feature is otherwise no longer activated.

27. An apparatus comprising:

a communication system switch operative to support enhanced feature access in a display-based mobile wireless user terminal of a communication system, the switch permitting the mobile wireless user terminal 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 enhanced feature access mode having navigation and activation mechanisms associated therewith, the navigation and activation mechanisms utilizing a keypad of the user terminal in conjunction with a display of the user terminal to provide access to features of the communication system not otherwise accessible utilizing the keypad, the keypad comprising a plurality of numeric keys and a plurality of non-numeric keys and being utilizable in entering a telephone number to be dialed.

28. An article of manufacture comprising:

a machine-readable storage medium storing one or more programs for providing enhanced feature access in a display-based mobile wireless user terminal of a communication system, the one or more programs when executed permitting the mobile wireless user terminal 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 enhanced feature access mode having navigation and activation mechanisms associated therewith, the navigation and activation mechanism utilizing a keypad of the user terminal in conjunction with a display of the user terminal to provide access to features of the communication system not otherwise accessible utilizing keypad, the keypad comprising a plurality of numeric keys and a plurality of non-numeric keys and being entering a telephone number to be dialed.
