Description

A kind of data dispatching method and access network equipment
Technical field
The application is related to the communications field, more particularly to a kind of data dispatching method and access network equipment.
Background technology
Under the High-speed Circumstances such as high ferro, user is had become using the business of networking and video traffic of user and is just needed, for example, At present the video traffic of main flow uses the video data download mechanism broadcast below on side, i.e., first download part video data, etc. When the partial video data is gradually used up, then follow-up video data is downloaded, to ensure the smoothness of video.But, in high ferro field In cordless communication network under scape, because high ferro has fireballing feature, this causes the translational speed of user also quickly, with it He compares scene, and the quality of wireless channel of user changes faster, and the frequency that user switches between cells is also uprised, if user Video data consume be over soon, but current quality of wireless channel is poor so that subsequent video data download it is slow, or even Cannot download, so result in the slack phenomenon of video playback.
Being presently used for solution to the problems described above mainly has：1st, user is by measuring current quality of wireless channel Access network equipment is reported to, access network equipment is according to current quality of wireless channel adaptive coding and modulating (Adaptive Modulation and Coding, AMC) selection modulating-coding strategy (Modulation and Coding Scheme, MCS), the MCS of optimum is selected to increase speed of the access network equipment to the transmission data of user；2nd, access network equipment is average Distribute interface-free resources for user, if having multiple users in access network equipment while there is downlink data etc. to be sent, these use Need to compete interface-free resources between family, and the distribution of interface-free resources is then by the strategy decision of base station.In present Access equipment, distribution Respectively strategy is used during resource, i.e., there are mean allocation interface-free resources between the user of downlink data in certain measurement period.
But, prior art 1 is fast-changing due to the scene lower channel quality in high-speed motion, when user scheduling The channel quality measurement amount for reporting cannot characterize the channel quality of scheduling instance, and MCS exponent numbers are selected and present channel quality Mismatch, can seriously reduce data transmission rate.If when channel condition is good, the MCS exponent numbers of selection are relatively low, and data are sent out Transmission rate is low, and interface-free resources are wasted to a certain extent.If when bad channel conditions, the MCS exponent numbers of selection are higher, The error rate of data is activation can increase, and cause data transmission rate low；And prior art 2 effectively considers the justice between user Property, but under high motion scenes, when video user position preferable in channel, because the strategy limits video user The maximum interface-free resources share that can distribute, prevent video user from the channel condition made good use of it is as much as possible it is data cached with The channel that reply subsequently will be deteriorated, still may cause when channel is deteriorated because the video data for caching is not enough, and occur broadcasting Caton phenomenon is put, the network experience of user is have impact on.
The content of the invention
This application provides a kind of data dispatching method and access network equipment, for current according to history grid Information revision The schedule information of grid, and the channel status of follow-up wireless grid in raster path and raster path is predicted, so as to select rationally Interface-free resources allocation strategy send data to user so that user obtains enough data, improves the network experience of user.
First aspect present invention provides a kind of data dispatching method, including：
Wireless grid is built, the raster path information of the wireless grid and the history grid of each wireless grid is obtained Information；
Determine the current grid residing for targeted customer, and obtain the schedule information of the current grid, the targeted customer For the user of data to be received；
Schedule information according to the history grid information and the preset principle of optimality of the current grid to the current grid It is modified；
According to the raster path information and current grid prediction raster path and target data amount, the number of targets It is targeted customer data volume to be received according to amount；
Each wireless grid in the raster path according to the raster path and the history grid information prediction Channel status；
According to the channel status of each wireless grid in the target data amount and the raster path, it is determined that money of eating dishes without rice or wine Source allocation strategy, the interface-free resources allocation strategy is used to carry out interface-free resources distribution to the targeted customer.
The motion of user in the scenes such as high ferro is fixed with circuit, and due to access networks such as the base stations near railway line The position of equipment is fixed, then for a user, the characteristics of the change of channel has regular strong, can be by whole piece circuit Originally unknown channel conditions, the history grid information and grid of the historic user of each wireless grid are recorded by wireless grid Lattice routing information, history grid information includes schedule information of the wireless grid etc., and raster path information record is all going through History user passes through the wireless grid for needing to pass through during the cell of access network equipment.In targeted customer's data to be received, mesh is determined Current grid residing for mark user, the scheduling according to the history grid information and the preset principle of optimality of current grid to current grid Information is modified, further according to raster path information and current grid prediction raster path and target data amount, target data amount For targeted customer's data volume to be received, according in raster path and history grid information prediction raster path each without wiregrating The channel status of lattice, according to the channel status of each wireless grid in target data amount and raster path, to current grid with Wireless grid afterwards selects interface-free resources allocation strategy, for carrying out interface-free resources distribution to targeted customer.With prior art phase Than according to the schedule information of history grid Information revision current grid, and predicting follow-up wireless in raster path and raster path The channel status of grid, so as to select rational interface-free resources allocation strategy to send data to user so that user obtains enough Data, improve user network experience.
With reference to first aspect present invention, in first aspect present invention first embodiment, the structure wireless grid is obtained The raster path information of the wireless grid and the history grid information of each wireless grid, including：
The RSRP of historical user feedback is received, wireless grid is divided according to the RSRP；
The history grid information of each wireless grid is recorded, the history grid information is the scheduling of all historic users Parameter, scheduling result, uplink power control parameter, uplink power control result and historical channel quality；
