Handling method and device for quality of service

Abstract

The invention provides a handling method and device for the quality of service (QoS). The method comprises the following steps that the air interface bandwidth of an uplink subframe is worked out; the moment for sending data messages is determined; according to the sequence that the priorities of the data messages are ranked from high to low, the data messages corresponding to the number of bytes of the air interface bandwidth of the uplink subframe are fetched out of a data message queue to be sent on the business level and are put into a hardware buffering queue of a long term evolution (LTE) modem; at the moment for sending the data messages, the data messages corresponding to the number of the bytes of the air interface bandwidth of the uplink subframe in the hardware buffering queue of the LTE modem are sent. Thus, the data messages high in priority can be sent in time, the phenomenon that the hardware buffering queue of the LTE modem is stuffed up and consequently the data messages high in priority are discarded is avoided, and the QoS of business is well guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and device for processing quality of service. Background technique [0002] figure 1 It is a schematic diagram of a networking structure of an application scenario of a long-term evolution (Long Term Evolution, LTE for short) router in the prior art. Such as figure 1 As shown, the network structure mainly includes an LTE router 1, a base station 2, a Layer 2 Tunneling Protocol (Layer 2 Tunneling Protocol, L2TP for short) access concentrator (L2TP Access Concentrator, LAC for short) 3 and an operator network (Internet Service Provider, referred to as ISP) 4, L2TP Network Server (L2TP Network Server, referred to as LNS) 6 and enterprise network user equipment 7. Wherein, the ISP 4 includes an LTE access network (not shown in the figure), an LTE core network (not shown in the figure), and an Internet Protocol (Internet Protocol, IP for short) co...

Problems solved by technology

[0010] Since the LTE Modem currently used by LTE routers does not support Quality of Service (QOS), the hardware itself has a large buffer area (such as 150,000 bytes) to cache the data stream sent by the service layer. When the interface bandwidth is insufficient and there are a large number of data packets to be sent at the service level, as described in step 3, the data packets with high priority will be queued after the low-priority data packets that have entered the buffer queue but have not been sent before. Since the LTE Modem sends the packets in the hardware buffer queue to the air interface sequentially, high-priority data packets cannot be sent in time, causing serious delay and delay jitter, priority inversion, and even when the buffer queue is full , high-priority data packets are discarded because they cannot enter the LTE Modem hardware buffer queue, and cannot reach the air interface for transmission at all, and the QOS of the service cannot be guaranteed
