Description
Technical field
The present invention relates to wireless mobile telecommunication technology field, more particularly to a kind of realization user QoS (Quality of
Service, service quality) method, apparatus and base station.
Background technology
In Satellite Communication System, forward direction uses DVB-S2 (Digital Video Broadcasting, standards for digital broadcasting
Agreement), communication main website realizes terminal forward traffic scheduling by controlling the content of downlink broadcast frame；Reversely use DVB-RCS2
(Digital Video Broadcasting-Return Channel Satellite, agreement satellite backhaul channel system) is marked
Quasi- agreement, MF-TDMA (Multi frequency-Time Division Multiple Access, multifrequency point time division transmission),
Inverse bandwidth resource distributes business time interval resource by terminal to the application of communication system main website, then by main website centralized dispatching, specifically
It is terminal by reporting BSR (Buffer Status Report, Buffer Status Report) to communication system main website, main website passes through
The signal-to-noise ratio state centralized dispatching inverse bandwidth resource of terminal PRI and terminal present position.Therefore, Satellite Communication System
It is two dimensions of downlink and uplink that user QoS, which is divided to,：For downlink since frame length is short, corresponding user is more, and QoS realizes that difficult point is a frame
Operand in processing time；Reversed scheduling of resource concentrates on main website, other than needing to consider operand problem, also needs to consider institute
There are the empty overhead and time delay that user BSR is reported.
Satellite Communication System is as shown in Figure 1, there are multi-user's under, big, the single slave station of propagation delay time big with coverage area
Feature, compared with traditional cellular communication system, the excited user number of satellite network list off the net thousand or ten thousand magnitudes leads to user
QoS realizes that there are many difficult points.
Downlink：
1. activating user volume big, scheduling computation amount is big.Since a user corresponds to a buffer, scheduling computation amount is huge
Greatly, in some instances it may even be possible to cannot achieve.By taking 45M downlink bandwidths as an example, the most short 290us of frame length, if there are 10000 users, i.e., 10000
Buffer completes sequence scheduling and resource allocation (also eliminating signaling and voice herein) in 290us, exists in realization very big
It is difficult；
2. satellite bandwidth is limited, it is necessary to face flow control problems.According to GBR, (Guaranteed Bit Rate are protected
Card rate) and MBR (Maximum Bit Rate, maximum rate) directly control the data of entrance air interface transmission in the unit interval
Amount, QoS guarantee rate and maximum rate are not easy to configure when user volume increases, and maximum rate configuration is too small, eats dishes without rice or wine to waste；Ensure speed
Rate configuration is too big, unfair between equal priority user；Guaranteed rate and maximum rate difference are too big, and rate is unstable, user
Experience is poor.
Uplink：
1. there are multi-user under single slave station, fairness is difficult to ensure between user.User data directly applies for BSR, eats dishes without rice or wine to provide
Source may be occupied by the big data quantity user of a small amount of equal priority not to be discharged, and other users rate can not ensure；
2. interface-free resources are valuable, resource bid expense accounting need to be controlled.One Buffer of each user, when user volume is big,
BSR signaling structures increase with number of users, increase bandwidth of air-interface resource consumption；
3. chain-circuit time delay is big.By taking reversed Burst Length are 536 waveform as an example, reversed time slot maximum Payload
Length is 194byte, and reversed frame length 20ms to 750ms is differed.With 2M bandwidth, for 20ms frame lengths, reversed minimum-rate
600kbps or so does not consider also to spread, and by taking single user 256kbps guaranteed rates as an example, 3 users use is surpassed under single slave station, is eated dishes without rice or wine
Just cannot meet, especially network application is all based on burst flow, when equal priority number of users increases significantly, certain customers'
Online request may can not all be transferred to core net in several seconds；
4. main website operation pressure is big.Each user corresponds to a buffer, and when user volume is big, main website centralized dispatching distribution is anti-
It is big to interface-free resources operation pressure.
If Satellite Communication System realizes user QoS using routine dispactching method in summary, not only require superelevation is
System operational capability, and also need to waste the relevant signaling of a large amount of bandwidth of air-interface resource transmission resource applications.

In letter system.
Fig. 4 is the realization block diagram of user QoS provided in an embodiment of the present invention, as shown in figure 4, including：Service message sorts
Module 301, message are joined the team strategy matching module 302 and dispatching message module 303.Wherein service message sorting module 301 is wrapped
Include protocol stacking unit；The message join the team strategy matching module 302 include flow controlling unit；The dispatching message module 303
Including schedule level one device and second-level dispatching device.Wherein protocol stacking unit, flow controlling unit, schedule level one device and second-level dispatching
Device, while residing in main website and slave station, divide the work cooperative achievement uplink and downlink business high priority or real time business preferentially go out team
And Delay Guarantee, the justice of same priority customer service go out team, packet loss does not reduce re-transmission to TCP traffic, and queue of eating dishes without rice or wine goes out the spirit of team
Configuration living.
Wherein, the protocol stacking unit (TCP that must include comprising satellite communication system accelerates), for type of service point
It picks.UDP business is directly placed into level-one buffer, and the data beyond buffer directly abandon；Speech business (RTP messages) is directly put
Enter two level buffer, into second-level dispatching, the real time business such as voice use semi-persistent scheduling, used after resource first to file, voice
Buffer will not be overstock；TCP traffic limits the data that socket is flowed by controlling TCP window, level-one tune is inquired before packet receiving
Spend flow-control module buffer surpluses, it is ensured that packet loss, reduction TCP do not retransmit the consumption to bandwidth of air-interface resource to TCP data,
Improve TCP traffic user experience simultaneously.The flow controlling unit enters the number of level-one buffer for control protocol stack cell
According to amount.It is joined the team as unit of IP packets, IP first inquires buffer states when being packed in group, packet loss cannot occurs for TCP message, i.e., not
The case where TCP message is beyond buffer can occur.
Wherein, the schedule level one device, uniformly goes out in team to two level buffer for equal priority user data, goes out team
Cycle T, T, two level buffer sizes, level-one buffer sizes refer to maximum capacity setting of eating dishes without rice or wine.Go out group window least unit
To be arranged using the practical ability of eating dishes without rice or wine of system as reference, while it can refer to IP packet MTU (Maximum Transmission in net
Unit, maximum transmission unit).Equal priority user under identical slave station can be used robin scheduling and enter two level buffer, nothing
It needs to sort, operand is little, and fairness is guaranteed.In addition, in order to ensure that the justice of second-level dispatching, schedule level one are also needed slave station
Under corresponding active users pass to second-level dispatching as scheduling a reference factor.The second-level dispatching device, for every
A access slave station corresponds to multiple two level buffer, at least by taking 5 buffer of single slave station as an example, signaling, hard real time for example voice, three
Service priority gold, silver and bronze.Signaling highest priority, voice take second place, secondly the users such as gold, silver and bronze medals.Voice is due to time delay
Jitter-sensitive is used always using semi-static mode after applying, discharges interface-free resources when stopping using in time, preceding reversed right
Claim.Data service gold, silver and bronze go out group priority difference, weigh fairness and real-time sexual intercourse, select different classical dispatching algorithms
(Round Robin, MAX C/I, Proportional Fairness) controls out group mode.By taking 20 user of single slave station as an example, such as
Fruit presses one buffer of each user, adds signaling and voice respectively to account for a buffer, single slave station needs 22 buffer, with 1000
For slave station, scheduler module needs to realize the sequence scheduling of (45M corresponds to 290us) 22000 buffer in a frame, realizes difficulty
Greatly.After introducing second-level dispatching, the sequence scheduling of 5000 buffer need to be only completed, it is assumed that dispatching algorithm is that O (n) algorithms are complicated
Degree, can reduce by 75% or more operand.By taking quicksort as an example, the most ideal worst time O (n^2) of O (nlogn), operand
Reduction amount is just more considerable, i.e., number of users is more under single slave station, and effect is more apparent.
The embodiment of the invention also includes resource bid modules, reside in slave station system.The centralized dispatching of uplink main website is reversed
Resource, slave station report BSR to main website by backward signaling, and main website completes centralized dispatching, and the size setting of each buffer needs to join
The limit capacity reversely eated dishes without rice or wine is examined, by taking 4 bytes report as an example, 5 buffer, mono- BSR request occupies 20 bytes, first Shen altogether
The mechanism please used afterwards, which determines, reports frequency influence service delay, reports the higher occupancy of eating dishes without rice or wine of frequency bigger.If without one
Grade is dispatched, and is needed 12 buffer, BSR to report for 10 users and is needed 48 bytes, occupy compared with the solution of the present invention more
One times or more interface-free resources, user is more, reports BSR more frequent, effect is more apparent.
That is, user data completes message sorting, differentiated service type after entering protocol stacking unit；Flow control list
Member controls same user's different types of data matching difference and joins the team strategy according to the schedule level one quene state of each user：TCP
Packet loss, voice are not transmitted into second-level dispatching, UDP (User Data Protocol, User Datagram Protocol) directly as possible；Level-one
The data of each user are liberally moved second-level dispatching queue with special speed, while notifying two by scheduler robin scheduling
Excited user number on the grade each slave station of scheduling queue；Second-level dispatching device is according to configuration strategy, and high priority dispatch signaling, half is quiet
State schedule voice, tradeoff slave station excited user number dynamic dispatching secondary queue go out team.
Fig. 5 is the implementation flow chart of user QoS provided in an embodiment of the present invention, as shown in figure 5, including：
Step S501：User data message；
Assuming that user 1 and 2 be Gold Subscriber, user 3 and 4 is Silver Subscriber, user 5 and 6 is Bronze Subscriber, such as Fig. 6 institutes
Show, user 1 and user 6 carry out VoIP business and data service at the same time.
Step S502：Service message sorts；
Delay sensitive business (such as RTP messages) takes semi-persistent scheduling mode, in advance apply interface-free resources ensure time delay and
The RTP messages of bandwidth, user 1 and user 6 directly enter two level buffer by flow control and are used for second-level dispatching, and user 6
Although data Buffer states are full, RTP message priorities are high, are directly sorted into two level Buffer, are not take up level-one
The spaces Buffer, without flow control.
Step S503：UDP messages transmit as possible；
UDP messages write direct buffer, if buffer remaining spaces are not enough to stored messages, abandon.User in figure one
2,3,6 Buffer states can all have UDP packet losses, and reason is that bandwidth of air-interface is insufficient.
Step S504：TCP message not packet loss；
TCP message first inquires buffer residue sizes before joining the team, enter buffer if remaining space is more than packet length, no
Then, adjustment TCP window is 0, by data buffering in socket.1 Buffer remaining spaces of user are stored paid-in enough
TCP message, TCP message are joined the team, and 3 Buffer states of user are full, all set to 0, do not receive for the TCP connection window of user 3
TCP data；User 4,5Buffer states are empty, and message is directly joined the team.
Step S505：Voice message is directly entered secondary queue；
Control plane signaling, resource bid signaling highest priority in system, and measuring will not be very big, and it is preferential to be directly entered highest
Grade signaling queue；Delay sensitive (VoIP RTP) message is directly entered voice scheduling queue.
Step S506：Schedule level one equity dispatching all customer data；
Schedule level one device as unit of the QoS window configured, QoS window as unit of IP layers of MTU 1500byte because
IP packet is needed completely to reach opposite end, GSE (Generic Stream Encapsulation, general flow encapsulation) frame decoding is just calculated very
Positive to complete, user behavior could really embody, and have an impact to time delay experience.According to the User Priority of configuration, data are moved in
The queue to be sent of gold, silver, copper, first query request residual capacity, ensures user's difference level-one using robin scheduling before moving
Data in Buffer enter the fairness of two level Buffer, as shown in fig. 7, Buffer1 and Buffer2 is Gold Subscriber, the
The sequence that primary scheduling enters in two level Buffer is B1, B2, and second of sequence will become B2, B1.It is not enough deposited in silver medal queue
The 4 data B4 of user for putting a complete QoS window, will supply next time, and bronze medal queue consumers 5, user 6 use identical benefit
Sufficient data method.In addition, providing the active users under corresponding slave station as one of scheduling factor to secondary scheduling module.
Step S507：Second-level dispatching different priorities data；
There can be multiple slave stations since a son is off the net, by taking N as an example, secondary scheduling module will be appreciated that N*5 two level tune
Spend buffer.Second-level dispatching can be used the classic algorithms such as PF (Particle Filter, particle filter) algorithm completion data and go out
The active users under different slave stations are weighed by team, complete the scheduling of different slave station different priorities queues.Slave station ascending resource Shen
The BSR that please be reported is the size of Buffer in Fig. 8.As shown in figure 8, signaling and voice, which all preferentially go out team, occupies interface-free resources,
Secondary gold, silver and bronze medals business.
Step S508：Data, which are sent to, eats dishes without rice or wine；
Step S509：According to second-level dispatching quene state application BSR.
Uplink service needs resource bid, resource bid module to generate BSR signalings according to uplink second-level dispatching buffer states
Apply for reversed resource.
The scheme provided according to embodiments of the present invention may be implemented the scheduling of Satellite Communication System user class QoS, pass through area
Divide customer service type, control TCP traffic packet loss, reduction TCP is retransmitted, covert raising air-interface efficiency and reduction customer service etc.
It waits for time delay, improves user experience, schedule level one is directly realized by the real time business such as semi-persistent scheduling voice, ensures the real-time industry such as voice
Priority of being engaged in and time delay are stablized, and by the way that multi-user service data justice to be mapped in a small amount of second-level dispatching buffer, reduce and adjust
Degree operand reduces Signalling length needed for resource bid simultaneously, and reduction eats dishes without rice or wine to occupy, and ensures the fair tune of equal priority user
Degree, the rate and time delay of high-priority service are controllable.
Although describing the invention in detail above, but the invention is not restricted to this, those skilled in the art of the present technique
It can be carry out various modifications with principle according to the present invention.Therefore, all to be changed according to made by the principle of the invention, all it should be understood as
Fall into protection scope of the present invention.
