A Method of Semi-Static and Dynamic Hybrid Scheduling in LTE System

Abstract

The invention discloses a semi-static and dynamic hybrid scheduling method applied to an LTE system. The method includes the following steps that: A, after SPS authorization activation is carried out on business applicable to semi-static scheduling, the business is identified as business which has been subjected to SPS authorization activation; B, when periodic new data arrive, if the business identified as the business which has been subjected to SPS authorization activation cannot be dynamically scheduled due to insufficient resources, and a part of data are left, the business is identified as SPS activation to-be-supplemented dynamical scheduling business, and the remaining data are cached as data to be transmitted; and C, the cached data to be transmitted are dynamically scheduled and transmitted, the business are restored and identified as business which has been subjected to SPS authorization activation. With the semi-static and dynamic hybrid scheduling method applied to the LTE system of the invention adopted, the data of the business in a cache region can be transmitted as quickly as possible in a wireless network, and the time delay of the business can be decreased, and the satisfaction of a user can be improved, signaling cost can be further decreased.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and relates to a semi-static and dynamic hybrid scheduling method in an LTE system. Background technique [0002] With the rapid development of mobile communication, the radio resources of the air interface have become one of the main bottlenecks in the further development of mobile communication systems. On the one hand, the research on physical layer technology, such as efficient coding technology, modulation technology, diversity technology, etc., is crucial to the improvement of system capacity; on the other hand, how to reasonably schedule, configure and manage wireless resources is of great importance to It is also very important to maximize system capacity and meet system requirements as much as possible. [0003] The dynamic shared resource scheduling mode adopted in the LTE system greatly optimizes the allocation of system resources. But on the other hand, becaus...

However, in the actual process, there is a certain difference in the size of the data packet during the transient period of the service and the activation period. In addition, during the network transmission process, there is jitter at the arrival time of the transmission packet, the difference in the size of the data packet after the PDCP layer header compression algorithm takes effect, and the size of the data packet in the network. In the case of burst packets and other situations, the use of fixed semi-static scheduling cannot guarantee the delay requirements of the business, and may cause data packets of the voice service to be lost due to timeout, reducing user experience and satisfaction
