| 20100318351 | SYSTEM AND METHOD FOR OBTAINING A MESSAGE TYPE IDENTIFIER THROUGH AN IN-BAND MODEM - A system and method is provided for obtaining a message type identifier through a speech codec (in-band) such as found in a wireless communication network. A first predetermined sequence with noise-like characteristics is detected and identifies a first message type. A second predetermined sequence with noise-like characteristics is detected and identifies a second message type. | 12-16-2010 |
| 20110142030 | SYSTEM AND METHOD FOR SUPPORTING HIGHER-LAYER PROTOCOL MESSAGING IN AN IN-BAND MODEM - Acknowledging a source terminal data message from a destination terminal in an in-band communication system is disclosed. A first synchronization sequence followed by a low layer acknowledgement message and a second synchronization sequence followed by a high layer acknowledgement message is transmitted. | 06-16-2011 |
| 20110149847 | SYSTEM AND METHOD FOR SUPPORTING HIGHER-LAYER PROTOCOL MESSAGING IN AN IN-BAND MODEM - Detecting an acknowledgment signal sent from a destination terminal at a source terminal in an in-band communication system is disclosed. A first synchronization sequence followed by a low layer acknowledgement message and a second synchronization sequence followed by a high layer acknowledgement message is detected. | 06-23-2011 |

| 20090304057 | SYSTEM AND METHOD OF AN IN-BAND MODEM FOR DATA COMMUNICATIONS OVER DIGITAL WIRELESS COMMUNICATION NETWORKS - A system is provided for transmitting information through a speech codec (in-band) such as found in a wireless communication network. A modulator transforms the data into a spectrally noise-like signal based on the mapping of a shaped pulse to predetermined positions within a modulation frame, and the signal is efficiently encoded by a speech codec. A synchronization sequence provides modulation frame timing at the receiver and is detected based on analysis of a correlation peak pattern. A request/response protocol provides reliable transfer of data using message redundancy, retransmission, and/or robust modulation modes dependent on the communication channel conditions. | 12-10-2009 |
