Abstract: Provided, inter alia, is a type of contest in which, at various intervals, geographically dispersed players attempt to answer the identical problem at substantially the same time. In representative embodiments, problems (typically, questions) are made available at seemingly random times throughout the day (or throughout some specified time interval), and players have the opportunity either to respond to the problem or (e.g., in the event that a given player is occupied when a particular problem arises) to pass on the current problem and wait for another one. In such embodiments, more questions are made available than the players are permitted to answer in accordance with the rules of the game, so that players have flexibility as to when they participate.

Abstract: Provided, inter alia, is a system for generating substantially simultaneous alerts, in which a plurality of user devices is accessible via at least one publicly available network. Each such user device has installed on it an alert-based client. A server is configured to download identical alert information, including a message that has been encrypted, to the plurality of user devices. The alert-based clients are configured to receive the alert information and, in response: (i) to store the message in encrypted form until just prior to a specified delivery time; and (ii) to decrypt and deliver the message substantially at the specified delivery time. By virtue of the foregoing arrangement, substantially simultaneous delivery of the message to the user devices is achieved.

Abstract: A method and apparatus for service level recognition and registration processing in a wireless communication device are provided. According to one aspect of the present invention, a method is provided for transitioning between service modes and indicating a current service mode to a user of a wireless communication device. The status of a signal associated with a forward channel from a messaging system to the wireless communication device is determined. A quality metric is determined based upon the status over a predetermined period of time. Three service modes, including a full service mode, a basic service mode, and a storing service mode are provided. In the storing service mode, after determining the quality metric is better than a first predetermined threshold a transition is made to the basic service mode. In the basic service mode, after verification of a reverse channel from the wireless communication device to the messaging system a transition is made to the full service mode.

Abstract: A method and apparatus for detecting duplicate messages and correcting garbled messages in a wireless communication device are provided. According to one aspect of the present invention, erred messages received by a wireless communication device are corrected. A first message fragment is received by the wireless communication device. The first message fragment is corrected based upon a second message fragment after it has been determined that the first message fragment contains one or more errors. According to another aspect of the present invention, a wireless communication device includes a receiver configured to receive messages transmitted over a forward channel from a messaging system; a transmitter configured to transmit responses over a reverse channel to the messaging system; and a processor. The processor is coupled to the receiver to receive messages from the messaging system. The processor is further coupled to the transmitter to transmit acknowledgments to the messaging system.

Abstract: In a paging system, a central paging station determines a preferred amount of time, or "sleep value," that a paging device is to be inactive during a paging cycle based upon the volume of page messages that paging device historically receives during given time periods. After determining a preferred sleep value, the central paging station creates and transmits a wake-up interval page message. The paging device receives the wake-up interval page message and changes its wake-up interval to correspond to the one contained in the received page message.

Abstract: An electronic messaging network comprises a network operation center and plural message terminals, all including memories for storing corresponding files of canned messages and associated message codes. To send a canned message, a calling party selects a canned message stored at one message terminal and transmits the assigned message code to a receiving party at another message terminal via the network operation center. The receiving terminal retrieves the selected canned message from its memory using the received message code for display to the receiving party. Files of canned responses and associated response codes may also be stored in the memories at the terminals and network operation center to allow the exchange of selected canned response options in conjunction with canned messages to be in response code form.

Abstract: A network operations center transmits a data message to a wireless mobile unit and waits for a data acknowledgment message. If no acknowledgment is received within a specified time, the network operations center sends a probe message to attempt to locate the mobile unit and waits for a probe acknowledgment message. If still no acknowledgment, the network operations center marks the data message as undelivered and stores it for future delivery. If a mobile unit receives a probe message while its transmitter is powered off, it displays an indication to the subscriber that there is a message waiting to be delivered. The subscriber can then dial into the network operations center to retrieve the message. Or, when the transmitter of the mobile unit is powered back on, the mobile unit sends a registration message to the network operations center; and upon receiving the registration message, the network operations center automatically re-transmits the undelivered data message to the mobile unit.
