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. Additionally, the processor is configured to correct garbled messages by determining whether or not a second message is a duplicate of the garbled message. If the second message is a duplicate of the garbled message, then the garbled message is corrected based upon the second message.
