Abstract

A cellular radiotelephone (10) includes a keypad (22) having a plurality of keys (22a, 22b) and a display device (20) for displaying information, including messages, to a user. A method includes the steps of: (a) transmitting a short message service (SMS) message from a network (32) to the cellular radiotelephone; (b) receiving the SMS message from the network and storing the message in a memory (24) of the cellular radiotelephone; (c) presenting the stored SMS message to a user; (d) determining if the presented SMS message requires a manual acknowledgment by the user and, if so, monitoring an output of the keypad to detect a single key depression by the user. The method further includes a step of (e) determining if the user'"'"'s single key depression is a correct manual acknowledgement and, if so, automatically generating and transmitting to the network a SMS manual acknowledgement message that includes an identification of the single key depressed by the user.

Claims

1. A method for operating a cellular radiotelephone of a type that is bidirectionally coupled to a network through an RF interface, said cellular radiotelephone comprising a keypad having a plurality of keys and a display device for displaying information, including messages, to a user, comprising the steps of:

transmitting a short message service (SMS) message from the network to the cellular radiotelephone;

receiving the SMS message from the network and storing the message in a memory of the cellular radiotelephone;

presenting the stored SMS message to a user;

determining if the presented SMS message requires a manual acknowledgment by the user and, if so, monitoring an output of the keypad to detect a single key depression by the user; and

determining if the user'"'"'s single key depression is a valid manual acknowledgement and, if so, generating and transmitting to the network a SMS manual acknowledgement message that includes an identification of the single key depressed by the user.

2. A method as set forth in claim 1, wherein if the step of monitoring detects that the user indicates that a next stored message is to be presented, before the currently presented message is acknowledged, the method includes a further step of inhibiting a presentation of a next SMS message.

3. A method as set forth in claim 1, wherein if the step of monitoring detects that the user indicates that a currently presented SMS message is to be erased, before the currently presented SMS message is acknowledged, the method includes a further step of erasing the currently presented SMS message without formatting and transmitting to the network a SMS manual acknowledgement message.

4. A method as set forth in claim 1, wherein if the step of monitoring detects that the user indicates that the presentation of stored SMS messages is to be terminated, before the currently presented SMS message is acknowledged, the method includes a further step of terminating the presentation of SMS messages, including the currently presented SMS message, without formatting and transmitting to the network a SMS manual acknowledgement message, and without erasing the currently presented SMS message from the memory.

5. A method as set forth in claim 1, and further comprising a step of displaying a message to the user for informing the user that the cellular radiotelephone has formatted and transmitted the acknowledgement message that includes the user'"'"'s acknowledgement signal.

6. A method for operating a cellular radiotelephone of a type that is bidirectionally coupled to a network through an RF interface, said cellular radiotelephone comprising a keypad having a plurality of keys and a display device for displaying information, including messages, to a user, comprising the steps of:

transmitting a short message service (SMS) message from the network to the cellular radiotelephone;

receiving the SMS message from the network and storing the message in a memory of the cellular radiotelephone;

presenting the stored SMS message to a user;

determining if the presented SMS message requires a manual acknowledgment by the user and, if so, monitoring an output of the keypad to detect a single key depression by the user; and

determining if the user'"'"'s single key depression is a depression of one of a predetermined set of keys and, if so, generating and transmitting to the network a SMS manual acknowledgement message that includes an identification of the single key depressed by the user.

7. A method as set forth in claim 6, wherein if the step of monitoring detects that the user indicates that a next stored message is to be presented, before the currently presented message is acknowledged, the method includes a further step of inhibiting a presentation of a next SMS message.

8. A method as set forth in claim 6, wherein if the step of monitoring detects that the user indicates that a currently presented SMS message is to be erased, before the currently presented SMS message is acknowledged, the method includes a further step of erasing the currently presented SMS message without formatting and transmitting to the network a SMS manual acknowledgement message.

9. A method as set forth in claim 6, wherein if the step of monitoring detects that the user indicates that the presentation of stored SMS messages is to be terminated, before the currently presented SMS message is acknowledged, the method includes a further step of terminating the presentation of SMS messages, including the currently presented SMS message, without formatting and transmitting to the network a SMS manual acknowledgement message, and without erasing the currently presented SMS message from the memory.

10. A method as set forth in claim 6, and further comprising a step of displaying a message to the user for informing the user that the cellular radiotelephone has formatted and transmitted the acknowledgement message that includes the user'"'"'s acknowledgement signal.

11. A radiotelephone, comprising:

a transceiver for bidirectionally coupling said radiotelephone to a telecommunications network through an RF interface;

a user interface comprising a display and a plurality of user activated data entry keys;

a memory; and

a controller coupled to said transceiver, said user interface, and to said memory, said controller operating under the control of a stored program and being responsive to a receipt of a short message service (SMS) message from the telecommunications network for storing the received SMS message in said memory and for presenting the stored SMS message to a user through said display, said controller further operating under the control of said stored program to determine if the presented SMS message requires a manual acknowledgment by the user and, if so, for monitoring an output of said user interface to detect an activation of a single data entry key by the user, said controller further operating under the control of said stored program to determine if the user'"'"'s single data entry key activation is an activation of one of a predetermined set of data entry keys and, if so, for generating and outputting to the transceiver a SMS manual acknowledgement message for transmission to the telecommunications network, said generated SMS manual acknowledgment message including an identification of the single data entry key that was activated by the user.

12. A radiotelephone as set forth in claim 11, wherein said user interface is an integral part of said radiotelephone.

13. A radiotelephone as set forth in claim 11, wherein at least a portion of said user interface is disposed outside of said radiotelephone.

14. A radiotelephone as set forth in claim 11, wherein individual ones of said plurality of data entry keys are activated by a user'"'"'s voice command.
