Method and apparatus for automatic power saving mode insertion when an unknown or an offensive receiver detected in a wireless access system

Abstract

Embodiments of the invention provide a method, system, etc. for automatic power saving mode insertion when an unknown or an offensive receiver detected in a wireless access system. A method comprises generating a look-up-table from AGWN payloads in a plurality of AGWN packets. The look-up-table is then transmitted from a transmitter to a receiver. Next, the method generates a coded packet from an AGWN packet in a data packet using the look-up-table, wherein a code from the look-up-table is substituted in place of the AGWN packet. Specifically, the substituting of the code from the look-up-table comprises substituting coded symbols representing AGWN payloads in the AGWN packets. Further, the generating of the look-up-table comprises generating the code to represent size and strength information regarding an AGWN, wherein the coded packet is generated with a size that is less than the data packet.

Description

BACKGROUND [0001] 1. Field of the Invention [0002] The embodiments of the invention provide a method, system, etc. for automatic power saving mode insertion when an unknown or an offensive receiver detected in a wireless access system. [0003] 2. Description of the Related Art [0004]FIG. 1 shows a typical digital quantized voice stream 100 in a communication channel. The diamond represented the bi-directional quantized active voice or useful source information, and the line represent the silent gap. More specifically, control component 110 is between voice components 120. The background nature noise is normally filtered out by the digital non-linear quantization. To add back to the realistic of feeling of channel connection and nature communication, noise packets are added to the voice codec (Coder Decoder). [0005] In a packet switched wired or wireless communication channel 200, a typical sequence of packets from a voice codec is laying out as illustrated in FIG. 2. More specificall...

AI Technical Summary

Benefits of technology

[0014] Accordingly, embodiments herein provide methods that transmit the far small sized code of the much larger sized AGWN payload; thus, the whole down stream functional block can effectively concentrate on the voice payload and significantly improve the efficiency of the channel. The effective channel capacity will store the code table (also referred to herein as the “codebook”, the “look-up-table”, and / or the “LUT”) in between the TX transmitter and RX receiver. After the decoding process of their represented AWGN, the RX receiver can then search the LUT the packet to get AWGN payload.

Problems solved by technology

First, the space in between the packet is the maximum separator time gap that can't be utilized due to separation needed in between packets.

This problem is that the AGWN being carry out with more and more coding along the output of source coding and send out all the way through modem, thus significantly degraded effective channel utilization.
