Abstract: A SYSTEM IS PROVIDED FOR TRANSMITTING INFORMATION THROUGH A SPEECH CODEC (IN-BAND) SUCH AS FOUND IN A WIRELESS COMMUNICATION NETWORK. A MODULATOR (235) 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.

Abstract: A system is provided for transmitting information through a speech codec (inband) 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 synchro-nization 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 modula-tion modes dependent on the communication channel conditions

Abstract: Techniques for retransmitting data via RLP in a CDMA (e.g., cdma2000) system with a first retransmission mechanism provided by the RLP and a second retransmission mechanism provided by an HARQ-CF. In one method, missing RLP frames are first detected (e.g., by a receiver RLP). A dynamic timer is then maintained (e.g., by a receiver HARQ-CF) for each RLP frame detected to be missing. The dynamic timers are event-driven and have variable time durations. Each dynamic timer is updated based on events known to the receiver HARQ-CF. Fixed timers with fixed time durations may also be maintained (e.g., by the receiver RLP) for the missing RLP frames. Whether or not a missing RLP frame is lost is determined based on the dynamic timer and the fixed timer (if any) maintained for the RLP frame. A NAK may be issued for retransmission of each RLP frame deemed to be lost.

Abstract: Method and apparatus for secure transmissions. Each user is provided a registration key. A long-time updated broadcast key is encrypted using the registration key and provided periodically to a user. A short-time updatedkey is encrypted using the broadcast key. The short-time key is available with each broadcast message,wherein sufficient information to calculate the short-time key is provided in an Internet protocol headerpreceding the broadcast content. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key.

Abstract: A method for detecting delayed data frames in a transport function includes the steps of comparing a frame sequence counter with a predetermined threshold value, detecting a delayed frame if the sequence counter exceeds the threshold value, and processing the detected delayed frame accordingly. In an RLP data transport protocol, the delayed frame may be processed as a retransmitted frame. The threshold value may be proportional to the maximum number of frames sent in a given bundle times the maximum delay, in units of frame intervals, between frames sent simultaneously over the air in the same frame interval.

Abstract: A novel and improved method and apparatus for providing an interface to a digital wireless telephone system compatible with standard analog wire line fax machines is described. To process a fax, a source interface waits until an interface to a destination fax machine has been established before establishing an interface to a source fax machine. The source fax transmission rate must be less than or equal to the destination fax transmission rate and the data rate of the digital channel. To establish the source fax interface at the proper rate, the source interface first selects and initial data rate from a set of standard fax transmission rates. The source interface sends unacceptable rate (failure to train) messages to the source fax machine until the source fax transmission rate is less than or equal to the data channel rate and the destination fax transmission rate. During fax processing, the destination interface inserts non-printing data (fill bits) if the destination fax transmission rate is greater than the source fax transmission rate. Fill bits are also inserted to compensate for transmission delays.
