Communication resource scheduling method and device

Abstract

The invention provides a communication resource scheduling method and device. The method includes: after the communication resource scheduling device detects that the voice service is established, recording the current state of the voice service as a transient state; when detecting that the voice service has a data packet to be sent, identifying the type of the data packet to be sent; When consecutive N data packets of the same type to be sent are identified, record the current state of the voice service as a steady state, where N is a natural number; activate communication resources for the voice service in the steady state according to the type. The method described in this embodiment overcomes the adverse effect brought by the SPS mode due to the large change in the length of the voice frame data packet in the transient state by selecting an appropriate scheduling method for the voice service in a steady state to activate resources, and avoids It reduces the waste of resources and avoids the shortage of resources, thus improving the rationality of resource utilization.

Description

technical field [0001] The present invention relates to a communication resource scheduling method and device, and belongs to the technical field of long-term evolution (Long Term Evolution, referred to as: LTE) private network cluster communication. Background technique [0002] Communication resource scheduling methods in the existing LTE system mainly include a Dynamic Scheduling (Dynamic Scheduling, DS for short) method and a Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS for short) method. Wherein, the dynamic scheduling method is to activate the corresponding communication resource according to the requirement whenever the requirement of the communication resource is detected. Although this method can maximize the use of communication resources, frequent resource activation processes will also bring large system scheduling overhead. [0003] The semi-static scheduling method is a scheduling method introduced for VoIP services. In this way, the base stati...

Problems solved by technology

The above-mentioned SPS method is a one-time activation and periodic use of communication resources. If the SPS method is used for activation at this time, too many communication resources will be activated for too long voice frame data packets, resulting in subsequent waste of resources. Too short voice frame data packets will activate too few communication resources, resulting in insufficient follow-up resources

[0005] When the activated communication resources are insufficient, in the prior art, a voice packet is frequently fragmented through the Radio Link Control (RLC) layer, and a voice packet is divided into multiple transmissions. , causing the number of retransmissions of a voice packet to increase

Moreover, since there is no Hybrid Automatic Repeat Request (HARQ) mechanism in the downlink in the private network, as long as one of the fragments is transmitted incorrectly, the entire voice frame data packet will be lost, which will seriously affect User's voice experience and communication quality
