The inventor notices in the invention process:
All to reach maximum possibility in the same moment very little due to the uplink traffic demand of each residential quarter of same base station, similarly, it is maximum that the UE number that each residential quarter of same base station switches simultaneously can not reach simultaneously yet, so present allocated bandwidth mode has produced waste to transfer resource.
on the other hand, the situation that causes transfer resource to degrade using due to the factors such as transmission equipment fault of transmission network is also very general, in this case, the not enough former bandwidth of transfer resource that causes distributing to eNodeB due to the part transmission node fault in transmission network, such as dropped to the situation of 90Mbps from 180Mbps, present technology may cause data traffic to be transmitted net losing, thereby for flow F1 owing to having passed to the base station from eating dishes without rice or wine, lost again and just wasted bandwidth of air-interface, for flow F2 and F4, having abandoned the packet that switches, can to make the user experience undoubtedly very poor, can cause the signaling procedure failure or postpone long for flow F3 and F5, the situation that causes conversation loss or handoff failure etc. to have a strong impact on service quality occurs.
Given this, provide the transfer resource allocative decision in a kind of LTE system in the embodiment of the present invention, in order to effective assignment problem of the eNodeB that solves S1 mouth in LTE transfer resource on EPC direction and the X2 mouth.Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Fig. 2 is transfer resource distribution method implementing procedure schematic diagram, as shown in the figure, can comprise the steps:
In enforcement, when determining the transmission bandwidth quota of each residential quarter of this cycle in step 201, it is the transmission bandwidth quota of determining with one of down-off or its combination, what obtain in step 201 so is the actual transmission data bulk of these flows, and what adjust in step 203 is the transmission bandwidth quotas of these flows of each residential quarter in next cycle.
F (1): the S1 mouth from eNodeB to the MME/S-GW direction on by the MAC of this residential quarter service traffics according to the business datum situation scheduling of the channel quality of eating dishes without rice or wine and UE;
That is, in the throughput of S1 mouth up direction (namely from eNodeB to the MME/S-GW direction) by the MAC of this residential quarter service traffics according to the business datum situation scheduling of the channel quality of eating dishes without rice or wine and UE;
F (2): the flow that process S1 mouth switches;
F (3): through the signaling message flow quantity of S1 mouth;
When F (4): UE can't harm switching between the base station, PDCP is dealt into the X2 mouth data traffic of target BS from source base station;

Then establish eNodeB and comprise N residential quarter, consider to determine that current is V_F (k) (unit is the bits per second) for this eNodeB uplink transmission resource total amount after the factors such as each bandwidth of cell, spectrum efficiency, transfer resource deficiency, k value 1..5, the implication of F (k) is with reference to aforementioned definitions.
Fig. 3 is the information interaction schematic diagram between M1, M2, M3, M4, Figure 3 shows that example, in step 203, can be as follows according to the execution mode of the data traffic volume of each residential quarter reality and the transmission bandwidth quota in each next cycle of residential quarter of transmission bandwidth modulation of quotas in this cycle:
(1) a module M1 is set in eNodeB, receives the notice from the transmission network Operation ﹠ Maintenance System, obtain above-mentioned parameter V_F (k), and the BYTES that is converted in cycle U1 counts V_Bytes_F (k)=V_F (k) * U1/8; In concrete enforcement, consider the total amount (V_F (k)) of transfer resource usually take bit/s as unit, and in algorithm the variable of back usually take byte as unit in computing, so change 1Bytes=8bits here.
(2) in each residential quarter of eNodeB, a module M2 is set respectively, be used for cell i (0.. (N-1)) is measured: for F (k), k value 1..5, measuring amount comprises the actual data volume T (k) [i] (take byte as unit) that sends in cycle U1, in concrete enforcement, can consider header overhead during statistics: for F1, F2 and F4 will add up GTP-U (GPRS Tunnelling Protocol for User plane, GPRS Tunnel Protocol-user's face; The expense of GPRS:General Packet Radio Service, GPRS)/UDP (UserDatagram Protocol, User Datagram Protoco (UDP))/transport layer protocol heads such as IP; For will the add up expense of SCTP (Stream Control Transport Protocol, stream control transmission protocol)/transport layer protocol heads such as IP of F3 and F5; Also namely, when the actual transmission data bulk that obtains with one of down-off or its combination, the expense of the GTP-U/UDP/IP transport layer protocol head that can add up:
The S1 mouth from eNodeB to the MME/S-GW direction on by the MAC of this residential quarter service traffics according to the business datum situation scheduling of the channel quality of eating dishes without rice or wine and UE;
The flow that process S1 mouth switches;
When UE can't harm switching between the base station, PDCP is dealt into the X2 mouth data traffic of target BS from source base station.
When the actual transmission data bulk that obtains with one of down-off or its combination, the expense of the SCTP/IP transport layer protocol head that can add up:
Signaling message flow quantity through the S1 mouth;
Signaling traffic on the X2 mouth.
(3) in each residential quarter of eNodeB, a module M3 is set respectively, is used for cell i (0.. (N-1)) is monitored and adds up the consumed byte number in this residential quarter in cycle U1, deduction has expended byte number from quota;
(4) parameter received according to (1) of M1 module, determine the transmission bandwidth quota QuotaF (k) [i] of each cell initial, and satisfy:
QuotaF(k)[0]+QuotaF(k)[1]+...+QuotaF(k)[N-1]＝V_BYTES_F(k)；
(5) the M1 module is configured to above-mentioned quota QuotaF (k) [i] the M2 module of respective cell on the border of each cycle U1, and indicate whether and need to do compensation (multiple reason is referring to the explanation in following (12)) to flow multiple in the last cycle, and to establish this cue mark in implementing be b; B value 0 when data volume T (k) [i] sum of the actual transmission of each residential quarter is no more than V_BYTES_F (k); Otherwise value 1;
(6) M2 reports the measured value described in (2) to M1 by cycle U1, the T that M1 reports according to M2 (k) [i], determining whether increases or reduce quota for certain residential quarter: if the QuotaF of cell i (k) [i]-T (k) [i]＜=deltaMin, this residential quarter adds set of cells A (k); Otherwise this residential quarter adds set D (k); Note | A (k) | be element number in set A (k), | D (k) | be element number in set D (k);
(7) if | D (k) | or | A (k) | be 0, no longer adjust the amount of each residential quarter;
(8) otherwise, residential quarter amount corresponding to each element in D (k) is updated to QuotaF (k) [j1]=T (k) [j1], with the amount surplus of each residential quarter in D (k) SumD (the k)=∑ (QuotaF (k) [j1]-T (k) [j1]) that adds up, j1 ∈ D (k); To residential quarter quota corresponding to each the element j2 in A (k) increase SumD (k)/| A (k) |, namely QuotaF (k) [j2]=QuotaF (k) [j2]+SumD (k)/| A (k) |;
(9) the M2 module arranges variables L eftScheBytesF (k) [i] according to this quota and current traffic statistics notice M3 module, this variable represents cell i for the current also assignable byte number of flow F (k), LeftScheBytesF (k) [i]=QuotaF (k) [i] when initial;
(10) " the bandwidth use module " of each residential quarter is (in concrete enforcement, can be: be MAC, be PDCP, be S1AP, be PDCP, be X2AP for F5 for F4 for F3 for F2 for F1) dispatch the byte number that needs to the M3 request when sending at every turn, M3 is that LeftScheBytesF (k) [i] response responds according to the maximum of current residual quota;
(11) " the bandwidth use module " of each residential quarter carries out the transmission of business according to the response of M3, thereby the total bandwidth sum of each cell scheduling can not surpass V_BYTES_F (k);
(12) the M2 module in cycle U1 to the statistics of various flows, be recorded as deltaF (k) [i]=T (k) [i]-QuotaF (k) [i] for above-quota byte number, for the situation deltaF that is no more than quota (k) [i]=0, the main cause that exceeds quota is that bandwidth use module is inaccurate to the estimation of packet header expense, such as, need to increase the transmission heads such as GTP-U/UDP/IP for F (1) from each PDCP-SDU that PDCP sends, but actual " bandwidth use module " MAC is due to the number of actual PDCP-SDU corresponding to flow that do not know to eat dishes without rice or wine, can only roughly estimate the number of actual data packet,
(13) after per cycle U1 finishes, M2 arranges the variables L eftScheBytesF (k) [i] of M3 module=QuotaF (k) [i]-deltaF (k) [i] * b again, so that flow multiple in the last cycle is done compensation, the value of b is set referring to above-mentioned (5);
(14) in each residential quarter of eNodeB, a module M4 is set respectively, the LeftScheBytesF (k) [i] of the cell i (0.. (N-1)) that M2 is calculated revises more accurately, estimates inaccuracy with the packet header expense that reduces in (12):
the first-class transport layer header expense of GTP-U/UDP/IP of considering increase can leave corresponding surplus, LeftScheBytesF (k) [i]=LeftScheBytesF (k) [i] * (1-(headerSize/ (headerSize+avgPdcpSduSize))), here headerSize represents the byte number sum of GTP-U/UDP/IP head and bottom transmission protocol header, avgPdcpSduSize represents that the average packet of PDCP in cycle U1 is long, the quota value in each the new cycle of residential quarter when the transmission head expense is not considered in the LeftScheBytesF on equal sign right side (k) [i] expression,
(15) in enforcement, when determining the initial transmission bandwidth quota of each each flow of residential quarter, can carry out decile by total transmission bandwidth quota, and/or, can give each flow of each residential quarter with total transmission bandwidth allocation of quota according to the priority of each residential quarter.
Concrete, the mode of determining (4) described quota can be decile, be QuotaF (k) [i]=V_Bytes_F (k)/N, be set as absolute value in the time of also can utilizing the information initializings such as priority of each residential quarter, equal V_Bytes_F (k) but should satisfy summation; And should satisfy QuotaF (k) [i]＞min (k), min wherein (k) for the implication of various flows is: for F (1), represent the flow summation of this cell uplink GBR business; For F (2), be expressed as the minimum bandwidth of this residential quarter S1 mouth handoff reservation; For F (3), be expressed as the minimum bandwidth that the S1 message order of this residential quarter is reserved; For F (4), be expressed as the minimum bandwidth of this residential quarter X2 mouth handoff reservation; For F (5), be expressed as the minimum bandwidth that the X2 message order of this residential quarter is reserved;
(16) implement, when setting cycle, can be according to eNodeB equipment the buffer memory ability when the of short duration super bandwidth and/or the expectation quality of controlling allocated bandwidth set.

The below describes with example again.
Embodiment 1:
Take F (1) flow as example:
(1) for an eNodeB who supports 3 residential quarters, because the reason of Bandwidth-Constrained is V_F (1)=60Mbps at the S1 mouth by the ascending resource that Operation and Maintenance distributes, conversion V_Bytes_F (1)=60M*100ms/8=750KBytes;
(2) QuotaF (1) [i] of initial each residential quarter of M1=750/3=250KBytes, i value 1..3; M1 configuration QuotaF (1) [i] is to the M2 module of each residential quarter;
(3) 100ms week after date, M2 reports the actual transmission data volume of 3 residential quarters to be respectively 252Kbytes, 250Kbytes, 150KBytes to M1; Get deltaMin=5Kbytes, A (k)={ 1,2}; D (k)={ 3};
DeltaF (1) [1]=252-250=2KBytes; This 2KBytes is because MAC equiband use module estimates that header is forbidden to cause;
deltaF(1)[2]＝deltaF(1)[3]＝0；
Due to 252+250+150＜750, so b=0;
(4) sumD (k)=250Kbytes-150Kbytes=100Kbytes,
QuotaF(1)[1]＝QuotaF(1)[2]＝250+100/2＝300KBytes；
QuotaF(1)[3]＝150KBytes；
(5) M2 notice M3 arranges variables L eftScheBytesF (1) [i]=QuotaF (1) [i]-deltaF (k) [i], namely
LeftScheBytesF(1)[1]＝300K-b*2K＝300KBytes；
LeftScheBytesF(1)[2]＝300KBytes；
LeftScheBytesF(1)[3]＝150KBytes；
(6) accuracy for guaranteeing to estimate, M2 can utilize M4 that LeftScheBytesF (1) [i] is processed, and after removing the expense of the transport layer header such as GTP-U/UDP/IP, LeftScheBytesF (1) [i] is issued to the M3 module again;
(7) bandwidth of each residential quarter is used module LeftScheBytesF (1) [i] scheduling according to M3 in the next cycle;
(8) follow-up will the continuation repeated from (3) to (7).
Embodiment 2:
Take F (2) flow as example:
(1) for an eNodeB who supports 3 residential quarters, because the reason of Bandwidth-Constrained is V_F (2)=6Mbps at the S1 mouth by the ascending resource that Operation and Maintenance distributes, conversion V_Bytes_F (2)=6M*100ms/8=75KBytes;
(2) QuotaF (2) [i] of initial each residential quarter of M1=75/3=25KBytes, i value 1..3; M1 configuration QuotaF (1) [i] is to the M2 module of each residential quarter;
(3) 100ms week after date, M2 reports the actual transmission data volume of 3 residential quarters to be respectively 26Kbytes, 28Kbytes, 24KBytes to M1; Get deltaMin=500Bytes, A (k)={ 1,2}; D (k)={ 3};
deltaF(2)[1]＝26-25＝1KBytes；deltaF(2)[2]＝28-25＝3KBytes；deltaF(2)[3]＝0；
Due to 26+28+24＞75KBytes, so b=1;
(4) M1 calculates: sumD (k)=25Kbytes-24Kbytes=1Kbytes,
QuotaF(2)[1]＝QuotaF(2)[2]＝25+1/2＝25.5KBytes；
QuotaF(2)[3]＝24KBytes；
(5) M2 notice M3 arranges variables L eftScheBytesF (2) [i]=QuotaF (2) [i]-deltaF (2) [i], that is:
LeftScheBytesF(2)[1]＝25.5K-b*1K＝24.5KBytes；
LeftScheBytesF(2)[2]＝25.5K-b*3K＝22.5Bytes；
LeftScheBytesF(2)[3]＝24KBytes；
(6) accuracy for guaranteeing to estimate, M2 can utilize M4 that LeftScheBytesF (2) [i] is processed, and after removing the expense of the transport layer header such as GTP-U/UDP/IP, LeftScheBytesF (2) [i] is issued to the M3 module again;
(7) bandwidth of each residential quarter is used module LeftScheBytesF (2) [i] scheduling according to M3 in the next cycle;
(8) follow-up will the continuation repeated from (3) to (7).
This embodiment shows, from the time span in some cycles, owing to estimating that the inaccurate excess traffic that causes has obtained compensation between consecutive periods, makes the total bandwidth sum of each cell scheduling be no more than V_F (2), namely is no more than 6Mbps.
