Implementation method, device and system of scheduling

Abstract

The embodiment of the invention provides an implementation method, device and system of scheduling, and relates to the field of communications. The priority of a user is automatically adjusted according to the processing delay of the user, the user requests are processed in accordance with the priority, and thus the processing capacity of the system is fully utilized, and the performance of the system is ensured. The method comprises the following steps of: determining the priority to which the user processing request currently belongs according to the processing delay of the user priority request and user priority information; if the user processing request is not recorded in a priority queue corresponding to the priority to which the user processing request currently belongs, then the user processing request is written into the priority queue corresponding to the priority to which the user processing request currently belongs; and under the condition that the processing device is in an idle state, reading the user processing request in an unempty highest-priority queue, if the highest-priority user processing request does not timeout, sending the highest-priority user processing request to the processing device. The embodiment of the invention is suitable for an adaptive scheduling scene.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a scheduling implementation method, device and system. Background technique [0002] The CDMA system has become the development direction of the third-generation mobile communication because of its high capacity, high service quality, and good confidentiality. In an actual CDMA communication system, there is a certain correlation between the signals of various users, so that multiple access interference (Multiple Access Interference) exists in the communication system. The multiple access interference caused by a single user is usually small, but when the number of users increases, for a certain user, the sum of the multiple access interference caused by other users is very large. When there is a near-far effect, when the signal amplitude of a certain user is relatively large, the multiple access interference caused by the user to a weak signal user is very large. Sin...

Problems solved by technology

[0006] In the process of realizing the above-mentioned scheduling, the inventor found at least the following problems in the prior art: When ensuring that the beneficiary users enjoy the cancellation gain, if the number of cancellation users is less than the number of beneficiary users, the system allocates the same number of cancellation treatments as the number of beneficiary users Time processing cancels users, so that the cancellation processing time is longer than the actual time required to process the canceled users, which increases the processing delay of the beneficiary users, and causes the data that some beneficiary users need to process to be delayed due to the processing delay exceeding the user's timeout time. are discarded and do not fully utilize the processing power of the system
