Embodiment 1

[0026] A pre-scheduling method based on service type provided by the present invention is introduced in detail. The service type can be divided into uplink service and downlink service, specifically, it can be divided into Transmission Control Protocol (Transmission Control Protocol, TCP) service, ICMP service, User Datagram Protocol (User Datagram Protocol, UDP) service and streaming media service, etc. , the embodiment of the present invention does not limit the specific service type.

[0027] Before the execution of a service type-based pre-scheduling method provided in the embodiment of the present invention, different pre-scheduling parameters need to be configured for different service types. The specific configuration rules are as follows: Pre-schedule the service type of the downlink service as TCP service and the uplink service as ICMP service, configure the pre-scheduling parameters, do not perform pre-scheduling for the service types of UDP service and streaming med...

Embodiment 2

[0044] A pre-scheduling method based on service type provided by the present invention is introduced in detail.

[0045] refer to image 3 , shows a flow chart of steps of a service type-based pre-scheduling method in an embodiment of the present invention.

[0046] Step 300, configure pre-scheduling parameters.

[0047] The Operation Maintenance (OM) module configures pre-scheduling parameters for the Packet Data Convergence Protocol (PDCP) module. The specific configuration rules can be explained according to the content about the configuration of the pre-scheduling parameters in the first embodiment, and will not be repeated here.

[0048] Step 302, process user service data, and transmit pre-scheduled user equipment information and pre-scheduled information.

[0049] When processing the uplink and downlink data, the PDCP module parses the packet header of the uplink and downlink data. For a specific parsing process, reference may be made to the parsing process of the d...

Embodiment 3

[0060] A pre-scheduling system based on service type provided by the present invention is introduced in detail.

[0061] refer to Figure 4 , shows a schematic structural diagram of a service type-based pre-scheduling system in an embodiment of the present invention.

[0062] The system may include: an analysis module 40 , a storage module 42 and a pre-scheduling module 44 .

[0063] The functions of each module and the relationship between each module are introduced in detail below.

[0064] The parsing module 40 is configured to parse the packet header of the uplink and downlink data when processing the uplink and downlink data.

[0065] The storage module 42 is configured to store the user equipment information and pre-scheduling information corresponding to the uplink and downlink data into a pre-scheduling queue if the analysis result indicates that the uplink and downlink data is a data packet of a preset service type. The pre-scheduling information includes: the next...

Abstract

The invention provides a pre-scheduling method and system based on a service type. The method comprises the steps of: when uplink and downlink data is processed, parsing a data package header of the uplink and downlink data; if a parsing result shows that the uplink and downlink data is a preset service type of data packet , storing user equipment information corresponding to the uplink and downlink data and pre-scheduling information into a pre-scheduling queue; and according to a pre-scheduling parameter and a discontinuous receiving parameter which are preset and correspond to the preset service type, carrying out a pre-scheduling operation on user equipment corresponding to the user equipment information in the pre-scheduling queue. According to the pre-scheduling method and system provided by the invention, an effect of executing the pre-scheduling operation on user equipment of a specific service type of data packet and not executing the pre-scheduling operation on user equipment of other service types of data packets is achieved, times of executing pre-scheduling are reduced, the time delay of the specific service type is saved, occupation for system resources is reduced, and interference caused by the fact that user equipment sends an idle packet in the case of no data transmission is also reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a pre-scheduling method and system based on service types. Background technique [0002] When the base station (eNodeB) of Time-Division Long Term Evolution (TD-LTE) does not enable the pre-scheduling function, the average delay of the Internet packet explorer (Packet Internet Groper, PING) 32Bytes is 35~ About 40ms, in order to shorten the delay, it is necessary to use the uplink pre-scheduling scheme to shorten the delay. [0003] The process of LTE uplink scheduling is as follows: figure 1 shown. After the user equipment (User Equipment, UE) uplink (UpLoad, UL) sends the channel sounding reference signal (Sounding RS, SRS) to the eNodeB (eNB), it is transmitted through the control message in the physical uplink control channel (Physical Uplink Control CHannel, PUCCH) An uplink scheduling request (Scheduling Request, SR) to the eNB requests uplink resources, a...
