摘要： A method and apparatus for reducing transmission delay in a wireless communication system that carries packetized voice and data information. Interruptions in the traffic channels cause loss of synchronization between a header compressor and a header decompressor. Rather than transmitting resynchronization information on the traffic channel, the information dropped by an interruption is re-transmitted on a non-traffic channel in parallel with the traffic channel. At the remote station, information from the traffic channel and the non-traffic channel is reassembled before input into the decompressor. Alternatively, the non-traffic channel can be used to carry overflow information so that a higher average data rate can be achieved than the average data rate of the traffic channel alone.

摘要： 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.

摘要： 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.

摘要： In a half-duplex communication system in which additional delays in the communication channel may cause a message collision between a message and a response, a collision detector is utilized to prevent and detect message collisions. The collision detector determines if a response may be transmitted from the communication device while it is receiving the current message. If no response is expected, the collision detector is placed into a train mode. If a response is possible, the collision detector is placed into the monitor mode. In the monitor mode, the collision detector monitors the communication channel and determines if a message collision has occurred during transmission of the message. A detection of a message collision causes retransmission of the message or possibly a new message at a later time after it has been determined that the communication channel is clear.

摘要： Micro-tunnels are used to provide multiple data service sessions to the same mobile node in a wireless communications system. Further, the flexibility of the micro-tunnels optimizes the resources of the system. On request for a data service, an encapsulation configuration record is generated. An encapsulation header is created in response to the encapsulation configuration. The encapsulation header includes a packet service identifier and a micro-tunnel identifier.

摘要： 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.

摘要： Apparatus and methods for supporting analog fax calls between two wireless subscriber stations in a tandem configuration are presented herein. To support the tandem configuration, full duplex communication may be established between the two base stations. Full duplex communication may be realized by incorporating an echo canceler in the base station, or by utilizing both BFSK channels of the V.21 fax system for communication. The tandem configuration may also be supported by advanced flag synchronization, wherein a second base station will immediately start sending preamble flags to a first base station after a message is transmitted from the first base station to the second base station. The first base station may then synchronize its receiver for immediate receipt of the return message from the second base station.
