Description
Technical field
The present invention relates to the communications field, more particularly to a kind of resource regulating method for HD video business.
Background technology
HD video business in 3G/4G wireless communication systems, scheduling of resource is carried out by base station, according to regarding
The up-downgoing demand of frequency business, distributes corresponding bandwidth resources.
When inadequate resource is to support video traffic, then need to carry out resource according to factors such as User Priorities to rob
Account for.In McWiLL systems, two kinds of preemption mechanisms are defined, be respectively common preemption mechanism and how preferential
Level preemption mechanism.
In the current realization, it is rather than certain terminal based on certain subcarrier group (SCG) commonly to seize.
That is, when certain terminal uplink/downlink resource allocation is unsuccessful, it is not to go to rob to other certain terminal
Resource is accounted for, but is robbed and is accounted on certain SCG, the uplink/downlink of the SCG is in race to control state.So,
The terminal resource for belonging to the SCG will carry out distribution bandwidth when matching somebody with somebody again according to minimum bandwidth, so that seizing
Terminal next time again with when be obtained in that enough bandwidth.Certainly, terminal may be robbed when seizing and account for this
The current SCG of terminal, it is also possible to rob and account on remaining SCG.
If in common preemption processes, terminal does not find the SCG that can suitably seize, then how excellent perform
First level preemption mechanism.In multipriority preemption mechanism, all terminals in system are divided into 8 according to priority
Class (Class=0,1,2 ... ..., 7), the wherein terminal of Class=7 has limit priority.Meanwhile,
Each Terminal Type total resources shared in systems are also different, and base station is according to the affiliated rank of each terminal total
The percentage (being calculated by formula) taken in resource to be terminal distribution resource.
When the available bandwidth of SCG disclosure satisfy that the bandwidth request of all users, SCG is in normal condition
(Flag=0).It is all to use the bandwidth that be successfully assigned to request per family；
When the available bandwidth of SCG can not meet the bandwidth request of all users, but the SCG total bandwidths are more than
During the minimum bandwidth sum of all users, SCG is in common race to control state (Flag=1).Now, user
Group (ClassType) is still invalid.User according to the sequencing matched somebody with somebody again, compression bandwidth, it is final each
With the resource that can obtain the minimum bandwidth for being at least greater than or equal to bandwidth template per family.
When the available bandwidth of SCG is less than the minimum bandwidth sum of all users, that is, no user can
To concede bandwidth again, SCG is in priority race to control state (Flag=2).Now, the group of user
(ClassType) effectively.By repeatedly matching somebody with somebody again, final high-priority users can be obtained at least above or waited
In the resource of the minimum bandwidth of bandwidth template.Low priority user can only obtain the most small band less than bandwidth template
Resource wide.
Above-mentioned Resource Scheduling Mechanism, the time on the one hand seized is more long, and on the other hand the mechanism is directed to all
The preempt-mode of user, not for video traffic.Therefore video terminal uses this preempt-mode, in spy
Under different video scene, resource may not be timely and effectively obtained.
The content of the invention
In order to fast and effeciently for HD video business carries out scheduling of resource, the present invention proposes that one kind is directed to
The resource regulating method of HD video business, the method includes：
HD video business is separated with ordinary video business, HD video business is by compressing ordinary video industry
The bandwidth on demand of business seizes the resource of ordinary video business, when HD video business is exited recover be preempted it is general
Logical video traffic.
Preferably, the bandwidth on demand of the compression ordinary video business is specially：By ordinary video service-user
According to User Priority order compression request bandwidth successively from low to high, until meeting HD video service bandwidth
Breach is compressed to video heartbeat bandwidth.
Further, above-mentioned compression request bandwidth using equation below specifically, change user's request bandwidth：
BwReqi_m=max (video heartbeat bandwidth, min (BwReqi, max (0, BwCoi-min (BwGap0
- idling-resource, max (BwCoj- video heartbeat bandwidth, 0))))), wherein, BwReqi_m is changed for user
Bandwidth on demand afterwards, BwReqi is user's current request bandwidth, and BwCoi is the current occupied bandwidth of user,
BwGap0 is current system bandwidth breach, and BwCoj is the current occupied bandwidth of more low priority user.
Preferably, the bandwidth on demand of the compression ordinary video business is specially：Traveled through according to User Priority
Each ordinary video service-user, compression request band is a width of successively maintains the 1/2 of bandwidthnIf having traveled through all
Bandwidth breach cannot be also met after ordinary video service-user, then continues repeatedly traversal, until meeting system band
Breach wide or user bandwidth are video heartbeat bandwidth, and wherein n is traversal number of times.
Further, the compression request bandwidth using equation below specifically, change user's request bandwidth：
BwReqi_m=max (video heartbeat bandwidth, min (BwReqi, max (0, BwCoi-min (BwGap0-
Idling-resource, max (BwCoj-max (video heartbeat bandwidth, BwSusj/ (2n)), 0))))), wherein,
BwReqi_m is the amended bandwidth on demand of user, and BwReqi is user's current request bandwidth, BwCoi
It is the current occupied bandwidth of user；BwGap0 is current system bandwidth breach, and BwCoj is used for more low priority
The current occupied bandwidth in family, BwSusj is the maintenance bandwidth of more low priority user.
The advantage of the invention is that：1, in the case where resource is inadequate, HD video user can seize general
Intervisibility frequency user resources, so as to meet demand of the HD video business to system bandwidth, and then ensure video industry
Carry out to business clear and smooth；2, the user being preempted can recover bandwidth after HD video user exits
Resource, the resource that the user in each state is distributed meets expection.

Embodiment one：Preemption algorithm step by step
The present embodiment is that according to User Priority, order is compressed successively from low to high by ordinary video service-user
Bandwidth on demand, until meeting HD video service bandwidth breach or being compressed to video heartbeat bandwidth.The above is adopted
The squeeze operation for taking, is realized by changing the bandwidth on demand of the user, and modification bandwidth on demand formula is as follows：
BwReqi_m=max (video heartbeat bandwidth, min (BwReqi, BwCoi- need to sell bandwidth)),
Wherein, BwReqi_m is the amended bandwidth on demand of user, and BwReqi is user's current request band
Width, BwCoi is the current occupied bandwidth of user；
User need to sell bandwidth=max, and (BwGap0- idling-resources-more low priority user is forced to sell
Bandwidth, 0),
Wherein, BwGap0 is current system bandwidth breach；
More low priority user forces that bandwidth=max (BwCoj- video heartbeat bandwidth, 0) can be sold,
Wherein, BwCoj is the current occupied bandwidth of more low priority user；
Finally merge into a formula：
BwReqi_m=max (video heartbeat bandwidth, min (BwReqi, max (0, BwCoi-min (BwGap0
- idling-resource, max (BwCoj- video heartbeat bandwidth, 0))))).
Finally, HD video business is seized step by step from lowest priority user to secondary high-priority users, is obtained
Obtain the bandwidth of ordinary video business.
After HD video business is exited, HD video service bandwidth breach is 0, now ordinary video business
Former bandwidth on demand will be recovered using above-mentioned bandwidth reduction formula, without specially treated.

The present embodiment is will to travel through each ordinary video service-user according to User Priority, successively compression request
With a width of maintenance bandwidth 1/2nIf having traveled through and cannot also meet after all ordinary video service-users bandwidth and lack
Mouthful, then proceed compression, it is video heartbeat until circulate operation meets system bandwidth breach or user bandwidth
Bandwidth, n represents that bandwidth reduction travels through number of times, is initialized as 1, after having compressed a wheel bandwidth on demand, compression
Number of times adds 1.
The squeeze operation that the above is taken, is realized by changing the bandwidth on demand of the user, modification request band
Formula wide is as follows：
BwReqi_m=max (video heartbeat bandwidth, min (BwReqi, max (BwSusi/ (2n), BwCoi- need to go out
Allow bandwidth))),
Wherein, BwReqi_m is the amended bandwidth on demand of user, and BwReqi is user's current request band
Width, BwSusi is the maintenance bandwidth in the bandwidth template of user, and BwCoi is the current occupied bandwidth of user；
User need to sell bandwidth=BwGap0- idling-resources-more low priority user and force that bandwidth can be sold；
Wherein, BwGap0 is current system bandwidth breach；
More low priority user force can sell bandwidth=BwCoj-max (video heartbeat bandwidth,
BwSusj/(2n))；
Wherein, BwCoj is the current occupied bandwidth of more low priority user, and BwSusj is used for more low priority
Maintenance bandwidth in the bandwidth template at family；
Finally merge a formula as follows：
BwReqi_m=max (video heartbeat bandwidth, min (BwReqi, max (0, BwCoi-min (BwGap0-
Idling-resource, max (BwCoj-max (video heartbeat bandwidth, BwSusj/ (2n)), 0))))),
Finally, HD video business will obtain the bandwidth of ordinary video business.
After HD video business is exited, HD video service bandwidth breach is 0, now ordinary video business
Former bandwidth on demand will be recovered using above-mentioned bandwidth reduction formula, without specially treated.
Above-mentioned reduced overall preemption algorithm is used for a scheduling of resource for McWiLL systems by the present embodiment.Money
