Link decision-making method and decision-making device

A decision-making computing device having one or more processors and memory storing a plurality of programs, the decision-making computing device being applied to a link decision-making system, the link decision-making system further comprising a first user equipment and a second user equipment that are in a Voice over Internet Protocol (VoIP) call status and a transit server, a first link directly connecting the first user equipment to the second user equipment and a second link that transits by using the transit server existing between the first user equipment and the second user equipment, wherein the plurality of programs, when executed by the one or more processors, cause the decision-making computing device to perform the following operations:

• receiving, by the decision-making computing device, audio service quality data reported by the first user equipment, the audio service quality data being determined by the second user equipment according to audio data sent by the first user equipment and being returned to the first user equipment;
• determining, by the decision-making computing device according to the audio service quality data, a link quality score of a current sending link of the first user equipment, the current sending link being the first link or the second link;
• and
• making, by the decision-making computing device according to the link quality score of the current sending link, a decision about using the first link or the second link as a subsequent sending link of the first user equipment, further including:
• determining, by the decision-making computing device, a decision-making model as an absolute threshold decision-making model according to stored historical link information that comprises only information about one type of link, wherein the one type of link is one of the first link and the second link, and a formula of the absolute threshold decision-making model is defined as:
• Thresholdabs=Thresholdabs0−Xn
• wherein Thresholdabs is a current absolute threshold, Thresholdabs0 is an initial absolute threshold, X is an attenuation parameter, and n is a total number of times of link handover up to now;
• and
• determining, by the decision-making computing device according to a determination that the link quality score of the current sending link is less than the current absolute threshold Thresholdabs and the decision-making model, one of the first link and the second link as the subsequent sending link of the first user equipment;
• and
• making, by the decision-making computing device, a decision about using another link as the subsequent sending link of the first user equipment, wherein the another link is the other of the first link and the second link.

A non-transitory computer readable storage medium storing a plurality of programs in connection with a decision-making computing device having one or more processors, the decision-making computing device being applied to a link decision-making system, the link decision-making system further comprising a first user equipment and a second user equipment that are in a Voice over Internet Protocol (VoIP) call status and a transit server, a first link directly connecting the first user equipment to the second user equipment and a second link that transits by using the transit server existing between the first user equipment and the second user equipment, wherein the plurality of programs, when executed by the one or more processors, cause the decision-making computing device to perform the following operations:
