Simultaneously, GBR for descending GBR business guarantees just to add that a penalty coefficient carries out Resources allocation assurance and restriction on the basis of GBR, GBR (1+10%) for example, the lower limit and the upper limit only adopt this value, also are to use this upper limit parameter as the upper limit to MBR.
The shortcoming that above-mentioned existing method exists professional descending QoS performance to be met specifically comprises following several aspect:
(1) owing to the GBR of the descending GBR business in 1 second carried out each TTI has been averaged, when business is little bandwidth, each TTI should the business correspondence logic channel to calculate the data volume of scheduling too little, to cause the resource byte number that distributes for current business too small, if the minimum byte data less than system can organize bag then will cause professional bust this;
(2) prior art is that the GBR mean allocation of all descending GBR business that UE is current is come scheduled transmission to each TTI (ms), when there is BLER (Block Error Rate in UE, Block Error Rate) time, the data that are not each TTI can both correctly be transmitted, thereby can't guarantee the GBR of descending GBR business;
(3) method of the increase penalty coefficient that adopts at present is that GBR and MBR adopt same value, can't satisfy the rate variation demand in GBR and MBR interval.

Embodiment
The objective of the invention is to propose a kind of scheduling of resource mode, be used for solving the QoS of survice performance requirement that has descending GBR business now and realize handling the shortcoming and defect that exists, so that better realize the GBR assurance of descending GBR business and the scheduling of resource in the MBR limit procedure.
Basic thought of the present invention is, descending GBR business is realized the scheduling of resource processing of transmission in the fixed range that GBR guarantees and MBR limits, promptly at first guarantee to satisfy GBR, resource just continues this GBR business is carried out scheduling of resource when residue is arranged, and limits according to MBR.
Based on above-mentioned thought, Fig. 1 and Fig. 2 show that the GBR that satisfies descending GBR business that the embodiment of the invention provides guarantees and the resource scheduling scheme of MBR restriction, and this scheme comprises scheduling preliminary treatment that resource allocation is preceding and the scheduling reprocessing two parts after the resource allocation.
As shown in Figure 1, the pretreated idiographic flow of scheduling of the scheduling of resource processing scheme that provides of the embodiment of the invention can comprise the steps:
Step 101, before each TTI scheduling, scheduling of resource " logic channel transfer resource " (referring to the resource that logic channel obtains) according to the history existence, to implementing Business Stream quantitative statistics on the professional corresponding logic channel of the descending GBR of each of each UE based on the transmission success in 1 second, obtain the statistical value of the service traffics of current total transmission success, hereinafter be called " successful service traffics " (Byte of unit);
Step 102, " successful service traffics " and the GBR and the MBR nominal value (bps of unit of this professional downstream arrangements of descending GBR (radio resource control RRC by eNB disposes by signaling) according to the professional descending logic channel of each descending GBR, satisfy configured rate needs data quantity transmitted in corresponding 1 second and be called " GBR " and " MBR ", the Byte of its unit), calculate this descending GBR business of this TTI and satisfy GBR needs data quantity transmitted size, hereinafter be called " GBR transmit buffering ":
" GBR transmit buffering "=" GBR "-" successful service traffics "
With reach MBR restriction and need the data quantity transmitted size, hereinafter be called " MBR transmit buffering ":
" MBR transmit buffering "=" MBR "-" successful service traffics ",
And calculate the two difference " Delta transmit buffering ":
" Delta transmit buffering "=" MBR transmit buffering "-" GBR transmit buffering ".
Step 103 to " MBR transmit buffering " summation of the descending logic channel of all signatory descending GBR business of this UE, draws " the MBR transmit buffering summation " of this UE;
Step 104, the size of actual total descending BSR value (Byte of unit) of current UE and " MBR transmit buffering summation " relatively, and get wherein that the smaller is used for the normal resource allocation flow as final BSR value;
Wherein, the purpose of getting the smaller is to determine the BSR value according to the actual amount of data size, like this, if " MBR transmit buffering summation " is little, then can accomplish the MBR restriction; If BSR is little, then can distribute according to actual amount of data, can not waste resource.
Step 105 is carried out UE resource allocation flow process according to LTE agreement regulation.
As shown in Figure 2, the idiographic flow of the scheduling reprocessing of the scheduling of resource processing scheme that provides of the embodiment of the invention can comprise the steps:
Step 201, be assigned to the UE of downlink resource by the normal resource allocation flow for each, be assigned on the descending logic channel of each GBR business according to its size " UE transfer resource " (UE actual allocated to the BSR value determined above may being less than or equal to of resource) (Byte of unit) that is assigned to real resource, at first can guarantee each descending GBR business descending " the GBR transmit buffering " of (GBR business hereinafter all refers to descending GBR business if no special instructions) in the following way:
For first descending logic channel, if " UE transfer resource " greater than " GBR transmit buffering ", then " logic channel transfer resource "=" GBR transmit buffering ", " UE transmits surplus resources "=" UE transfer resource "-" GBR transmit buffering "; Otherwise, " logic channel transfer resource "=" UE transfer resource ".
Step 202 judges whether non-last GBR business, and UE residue transfer resource＞0, if not last GBR business, and UE residue transfer resource＞0, then return step 201; Otherwise, execution in step 203;
Step 203 judges that whether UE residue transfer resource is greater than 0, if then execution in step 204; Otherwise execution in step 206;
Wherein, the purpose of this step 202 and step 203 is that " GBR transmit buffering " part of descending GBR business all among this UE is handled one by one, after descending " the GBR transmit buffering " of first descending logic channel surplus resources is arranged if promptly guarantee, then guarantee descending " the GBR transmit buffering " of second descending logic channel again according to " UE transmits surplus resources ", by that analogy.
Step 204, after the GBR of all signed descending GBR business of current UE guaranteed to finish, previous step is handled the descending logic channel that descending surplus resources " UE the transmits surplus resources " basis " Delta transmit buffering " that obtains is distributed to each GBR business, to obtain the restriction effect to the MBR upper limit, concrete assigning process is as follows:
If " UE transmits surplus resources " is greater than " Delta transmit buffering ", then " logic channel transfer resource "=" logic channel transfer resource "+" Delta transmit buffering ", at this moment, upgrade " UE transmits surplus resources " " UE transmission surplus resources (upgrading the back) "=" UE transmission surplus resources (before upgrading) "-" Delta transmit buffering "; Otherwise, " logic channel transfer resource "=" logic channel transfer resource "+" UE transmits surplus resources ".
Step 205 judges whether non-last GBR business, and UE residue transfer resource＞0, if not last GBR business, and UE residue transfer resource＞0, then return step 204; Otherwise execution in step 206;
Wherein, this step is the equal of that " the Delta transmit buffering " of GBR business all among this UE handled one by one, promptly at UE transmission surplus resources, earlier after carrying out the MBR restriction on first descending logic channel, if also have surplus resources, then on second descending logic channel, carry out the MBR restriction ... until " UE transmits surplus resources " is zero, the whole end of transmissions of downlink transfer resource.
Step 206, the resource of descending logical channel assignment is: " logic channel transfer resource "=" logic channel transfer resource "+" Delta transmit buffering ";
Step 207 is organized corresponding scheduling result and transmission according to the descending logic channel scheduling of resource of UE distribution result.
Describe in further detail below in conjunction with the enforcement of concrete application example of the present invention technical solution of the present invention.The concrete implementing procedure of this application example is as follows:
One, scheduling preliminary treatment:
1, historical traffic statistics:
Historical flow summation " successful service traffics " in professional 1 second of the UE signed descending GBR obtain the mode that adopts sliding window statistics, each TTI uses a buffering window, 1000 TTI were arranged in 1 second,, keep the method for 1 second throughput so statistics needs 1000 buffering windows altogether:
(1) if the professional downstream feedback of the GBR of the UE that current TTI eNB scheduler subsystem is received is Ack (Acknowledgment, confirm), then on " successful service traffics ", add previous T TI " logic channel transfer resource ", deduct " the logic channel transfer resource " of the previous TTI preservation in 1 second;
(2) if receive for Nack (Negative Acknowledgment, Negative Acknowledgement), then do not add " the logic channel transfer resource " of previous T TI, only deduct " the logic channel transfer resource " of a TTI the earliest who preserved before 1 second;
2, the professional descending logic channel scheduling of resource preliminary treatment of the GBR of UE:
Example: it is LCH1 and LCH2 that the professional corresponding descending logic channel of two GBR is arranged under the UE,
(1) GBR of LCH1 and MBR configuration distributes and not to be 1Kbps and 1.5Kbps, and the GBR of LCH2 and MBR configuration distribution Wei 1.5Kbps and 2Kbps;
(2) " the successful service traffics " that count are respectively LCH1 100Bytes, LCH2 120Bytes;
(3) the total BSR value of UE is 200Bytes.
Concrete result is as follows:
The first step: calculate " GBR transmit buffering ", " the MBR transmit buffering " and " Delta transmit buffering " of the professional descending logic channel of two GBR,
LCH1: " GBR transmit buffering "=1000/8-100=125-100=25Bytes
" MBR transmit buffering "=1500/8-100=187.5-100=87.5Bytes
" Delta transmit buffering "=87.5-25=62.5Bytes
LCH2: " GBR transmit buffering "=1500/8-120=187.5-120=67.5Bytes
" MBR transmit buffering "=2000/8-100=250-120=130Bytes
" Delta transmit buffering "=130-67.5=62.5Bytes
Second step: calculate " MBR transmit buffering " sum of the professional descending logic channel of two GBR, " MBR transmit buffering summation "=87.5+130=217.5Bytes;
The 3rd step: relatively the actual total BSR value of UE is got little person with the size of " MBR transmit buffering summation " value and is the BSR that UE is used for Resources allocation, because BSR＜" MBR transmit buffering summation " got final BSR=200Bytes.
Two, scheduling reprocessing:
1, the professional descending logic channel resource pre-scheduling of the GBR of UE is handled:
The first step: according to the professional descending logic channel scheduling of resource preliminary treatment result of UE two GBR, " UE transfer resource " that UE distributes by the normal resource allocation flow distributed to each descending logic channel, guarantee GBR earlier, the final BSR value 200Bytes that calculates when " UE transfer resource " that if this UE is assigned to is preliminary treatment
LCH1: " UE transfer resource "＞" GBR transmit buffering " be " logic channel transfer resource "=" GBR transmit buffering "=25Bytes then
" UE transmits surplus resources "=" UE transfer resource "-" GBR transmit buffering "=175Bytes
LCH2: " UE transfer resource "＞" GBR transmit buffering " be " logic channel transfer resource "=" GBR transmit buffering "=67.5Bytes then
" UE transmits surplus resources "=" UE transfer resource "-" GBR transmit buffering "=107.5Bytes
Second step: judge " UE transmits surplus resources "＞0, then continue " MBR transmit buffering " and the difference part between " GBR transmit buffering " of assignment logic channel, with the upper limit of restriction MBR,
LCH1: " Delta transmit buffering "＜" UE transmits surplus resources ",
Then " logic channel transfer resource "=" logic channel transfer resource "+" Delta transmit buffering "=25+87.5=112.5Bytes
" UE transmits surplus resources "=" UE transmits surplus resources "-" Delta transmit buffering "=107.5-87.5=20Bytes
LCH2: " Delta transmit buffering "＞" UE transmits surplus resources ",
Then " logic channel transfer resource "=" logic channel transfer resource "+" UE transmits surplus resources "=67.5+20=87.5Bytes,
And " UE transmits surplus resources "=0Bytes.
The 3rd step: the result issues according to the descending logic channel scheduling of resource of UE distribution result organizational scheduling, at this moment, when issuing, the scheduling result of UE can have following content, " the logic channel transfer resource " of " UE transfer resource ", LCH1 and " the logic channel transfer resource " of LCH2.
Simultaneously, " the logic channel transfer resource " that obtains through reprocessing is used for the historical throughput statistics of success of descending logic channel group here, and then decision scheduling of resource is next time handled.
