Problems solved by technology

[0004] However, in fact, the header length of each voice service data packet is not the same, and the resources pre-configured by the SPS in the prior art cannot meet the resource requirements of the voice data packet, thereby causing the voice data packet to not be transmitted in time; Latency and packet loss rate cannot guarantee business service quality and affect user experience

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0025] figure 1 The flow chart of the compensation scheduling method provided by the embodiment of the present invention, such as figure 1 As shown, the method includes:

[0026] Step 101: Receive the BSR sent by the UE at the SPS period point.

[0027] Here, the compensation scheduling method provided by the embodiment of the present invention can be applied to a scenario using the SPS scheduling technology. For example, the compensation scheduling method can be applied to an SPS scheduling scenario for VoIP services in an LTE system. The execution subject of the compensation scheduling method provided by the embodiment of the present invention may be a compensation scheduling device, and the compensation scheduling device may be set inside the network access device, or con...

Abstract

Embodiments of the invention disclose a compensation scheduling method. The method comprises the following steps of receiving a buffer status report (BSR), which is sent by user equipment (UE) at a semi-persistence scheduling (SPS) periodic point; and when preconditions are determined to be met according to the BSR, sending a dynamic resource allocation message including compensation scheduling resources to the UE, wherein the dynamic resource allocation message is used for enabling the UE to use the compensation scheduling resources to transmit a business data packet corresponding to the BSR. The embodiments of the invention further disclose a compensation scheduling device.

Description

technical field [0001] The invention relates to resource scheduling management technology in the field of mobile communication, in particular to a compensation scheduling method and device. Background technique [0002] VoIP (Voice over Internet Protocol) service adopts IP data transmission technology, without 2G / 3G network support, VoIP service can be carried on the Long Term Evolution (LTE, Long Term Evolution) network; because there are many voice users and the voice service has Due to the characteristics of periodic packet sending, relevant control information needs to be sent every time it is transmitted, so the overhead of control information is very large; for real-time services whose data packet size is relatively fixed and the arrival time interval satisfies certain rules, semi Static scheduling (SPS, Semi-persistence Scheduling) technology to reduce the overhead of control information; SPS technology is designed for specific services, using pre-allocated resources ...
