AI Technical Summary

Benefits of technology

This technology allows for efficient transmission between two devices without having them communicate with each other over an intermediary device called a server or relaying system (S). When one party wants something done on their behalf, they send it along with its own code-matched data set into another S computer network where this collaboration happens. They then use these codes back together again when needed. By selecting which coding method will work best based on how well the receiving process works, there's no longer any waiting times at all.

Problems solved by technology

Technics: The technical problem addressed in this patented method relates to improving the efficiency at transmitting data over a network with high delays caused by packet based signalling systems like SMTP or HTTP. Current solutions involve reducing the size of messages sent through these networks while still being able to send their content quickly enough without causing any issues during decoding process.

Embodiment Construction

[0019] The core idea of ​​the present invention is: the communication end initiates a compression algorithm negotiation request to the communication peer end, and the communication peer end negotiates with the communication end to select a compression algorithm supported by both parties.

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0021] figure 1 It is a flowchart of Embodiment 1 of the method of the present invention, as figure 1 As shown, before the communication terminal and the communication peer need to compress the exchanged information and transmit it, the following steps are included:

[0022] Step 100: The communication end carries the compression algorithm information of the compression algorithms supported by itself in the compression algorithm negotiation request and send

Abstract

The invention discloses a method for determining a decompression algorithm and a system thereof, before the transmission of the compressed information to be exchanged by a communication end and a communication opposite end, the communication end send a request of a compression algorithm protocol to the communication opposite end which negotiates with the communication end to select out a compression algorithm supporting by both parts. The invention, as the two communication parts negotiate and select out a compression algorithm supported by both parts, in the following information exchange process, can compress/decompress information by the local supported compression algorithm thereof, thereby reducing decompression time as well as the time delay of information exchange.
