Embodiment one
A kind of schematic flow sheet collecting the dispatching method of up GBR traffic that Fig. 1 provides for the embodiment of the present invention one.As shown in Figure 1, the dispatching method of this up GBR traffic comprises the following steps:
101, base station is that terminal is preset maximum amount of data that in unit period, maximum bit rate MBR is corresponding and ensured the minimum data amount that bit rate GBR is corresponding.
In the present embodiment, base station is according to third generation partner program (The3rd Generation PartnershipProject, be called for short 3GPP) maximum bit rate (Maximum Bit Rate is called for short MBR) of the pre-configured correspondence of the GBR traffic being defined as terminal in agreement.The message transmission rate of the GBR traffic in 3GPP agreement between prescribed terminal and base station can not exceed default MBR.The data volume that terminal sends to base station using this MBR preset by base station in unit period, as the corresponding maximum amount of data of MBR, is designated as Data_Max.
Further, base station is according to the GBR of the pre-configured correspondence of the GBR traffic being defined as terminal in 3GPP agreement.The message transmission rate of the GBR traffic in 3GPP agreement between prescribed terminal and base station will reach default GBR, if the situation lower than this GBR appears in message transmission rate, will affect the normal transmission of GBR traffic, thus reduces Consumer's Experience.In the present embodiment, the data volume that terminal sends to base station using this GBR preset by base station in unit period, as minimum data amount corresponding to GBR, is designated as Data_Min.36 serial protocols regulation MBR of 3GPP agreement are greater than GBR.
Need to illustrate, the service quality class identifier of the unit period in the present embodiment corresponding to GBR traffic (Quality of Service Class Identifier is called for short QCI) receptible time delay is determined herein.Wherein, described time delay can be tabled look-up according to 36 serial protocols of 3GPP and QCI grade and be obtained.
102, base station statistics obtains the GBR data volume that the upper line number biography subframe of terminal in current period sends.
The GBR data volume obtaining the upper line number biography subframe of terminal within each cycle and send over periodically is added up in base station.In the present embodiment, the uploading number of terminal in current period is passed the GBR data volume that sends of subframe and is designated as Data_GBR by base station.
Wherein, before the GBR data volume that the upper line number biography subframe of base station statistics acquisition terminal in current period sends, also comprise:
In order to make terminal can send data to base station, needing in initial time base station for the initial interface-free resources of terminal distribution, in this initial interface-free resources, sending data to base station to make this terminal.
103, base station is according to maximum amount of data, minimum data amount and GBR data volume, and judging whether needs to carry out interface-free resources scheduling to terminal.
Particularly, minimum data amount GBR and data volume are made difference and obtain the first difference by base station, judge whether the first difference is greater than zero further, if the first difference is greater than zero, illustrate that GBR data volume is lower than minimum data amount, namely the user that this terminal is corresponding does not meet user for GBR, and now base station is the demand that interface-free resources that this terminal has been authorized can not meet corresponding GBR traffic, and base station is then judged to need to carry out interface-free resources scheduling to terminal.
If 104 judged results are yes, the GBR data volume to be passed that base station is current according to the terminal obtained from the buffer status report BSR of terminal to report is the corresponding interface-free resources of authorization terminal.
Particularly, base station obtains the current channel quality of eating dishes without rice or wine of terminal, for terminal selects the modulation corresponding with channel quality of eating dishes without rice or wine and coding strategy (Modulation and Coding Scheme, be called for short MCS) exponent number, be that described terminal determines corresponding Resource Block (ResourceBlock is called for short RB) according to GBR data volume to be passed and MCS exponent number.Base station to the RB determined described in authorization terminal, sends data to base station to make terminal by CCE on described RB.Wherein, buffer status report (the BufferStatus Report that base station receiving terminal reports, be called for short BSR), this BSR is used for signals base terminal has total how many data waiting for transmission to exist in upper row buffer, and such base station just can get the current data to be transmitted amount of terminal from this BSR.
Further, the corresponding multiple terminal in base station in reality, first terminal can be called by needing the terminal of carrying out interface-free resources scheduling in the present embodiment, if when described first terminal is at least 2, the first corresponding for each first terminal difference and the GBR rate value preset can be obtained the first ratio as ratio by base station, and this first ratio and the cycle of presetting are obtained the second ratio as ratio.Sort according to the descending dispatching priority to each first terminal of the second ratio of each first terminal in base station, according to the order of described dispatching priority, from the described BSR that each described first terminal reports, obtain the GBR data volume to be passed that each first terminal is corresponding, be the corresponding interface-free resources of each first terminal mandate according to described GBR data volume to be passed.
The dispatching method of up GBR traffic provided by the invention and base station, base station is that the GBR traffic of terminal presets maximum amount of data corresponding to MBR in unit period and minimum data amount corresponding to GBR, obtain the GBR data volume that the upper line number biography subframe of terminal in current period sends, judge whether to carry out interface-free resources scheduling to this terminal according to GBR data, maximum amount of data and minimum data amount, if judged result is yes, the to be passed GBR data volume current according to the terminal obtained from the BSR of terminal to report is the corresponding interface-free resources of authorization terminal.In the present embodiment, base station is by the GBR data volume of the actual transmissions of terminal in current period and maximum amount of data and minimum data amount, judge whether to carry out interface-free resources scheduling to terminal, when needs are dispatched, for the interface-free resources that the current GBR data volume to be passed of authorization terminal and terminal is corresponding, no longer need to dispatch terminal in each TTI, improve the flexibility of scheduling, and reduce scheduling times, thus reduce taking CCE resource.
Embodiment two
The schematic flow sheet of a kind of up GBR traffic dispatching method that Fig. 2 provides for the embodiment of the present invention two.As shown in Figure 2, this up GBR traffic dispatching method comprises the following steps:
201, base station is that the GBR traffic of terminal presets maximum amount of data corresponding to MBR in unit period and minimum data amount corresponding to GBR.
202, base station obtains the GBR data volume that the upper line number biography subframe of terminal in current period sends.
Step 201 ~ step 202 detailed process, see step 101 ~ step 102 in above-described embodiment one, can repeat no more herein.
203, base station obtains the first difference between minimum data amount and GBR data volume.
If 204 first differences are greater than zero, base station judges to need to carry out interface-free resources scheduling to terminal.
Minimum data amount Data_Min and GBR data volume Data_GBR is made difference and obtains the first difference by base station.If whether this first difference is greater than zero, if judge that the first difference is greater than zero, illustrate that the Data_GBR received in current period is lower than Data_Min, namely base station is the normal transmission that interface-free resources that this terminal has been authorized can not ensure GBR traffic, and base station performs step 204; If judge the GBR traffic data statistics amount (Data_GBR) that receives in this cycle data volume (Data_Min) higher than the GBR corresponding cycle, base station needs to perform step 205.
205, the GBR data volume to be passed that base station is current according to the terminal obtained from the BSR of terminal to report is the corresponding interface-free resources of this authorization terminal.
Particularly, base station obtains the channel quality of eating dishes without rice or wine of terminal, and selects suitable MCS exponent number according to this channel quality of eating dishes without rice or wine, and selects rank according to terminal GBR data volume to be passed and MCS, obtains this terminal and uploads the required RB number of resources of distributing of GBR data volume to be passed.Base station is the RB resource that this terminal distribution is enough in conjunction with community remaining RB resource again.The RB that base station is distributed to authorization terminal by CCE, sends data to base station to make terminal on the RB distributed.
If 206 first differences are less than zero, base station judges that whether GBR data volume is higher than maximum amount of data.
When the first difference is less than zero, if judge that GBR data volume Data_GBR is higher than maximum amount of data Data_Max, illustrate that base station is that the interface-free resources that terminal has been distributed is sufficient, make the transmission rate of terminal GBR traffic higher than MBR, base station needs to perform step 207; If judged result be GBR data volume not higher than maximum amount of data, namely judge that GBR data volume is between maximum amount of data and minimum data amount, base station perform step 209.
207, stopping is carried out interface-free resources scheduling to described terminal by base station in current period.
208, the second difference between GBR data volume and maximum amount of data is counted described base station and adds up in the GBR data volume obtained when next cycle by base station, using described second difference with add up the GBR data volume that obtains be worth described GBR data volume within next cycle described.
209, the dispatching priority of described terminal is arranged on after all first differences are greater than the first terminal of zero by base station.
If judge that GBR data volume is not higher than maximum amount of data in step 207, namely judge that GBR data volume is between maximum amount of data and minimum data amount, illustrate that the message transmission rate of the GBR traffic of current period satisfies the demands, message transmission rate reaches default GBR and does not exceed MBR, and can meeting consumers' demand of GBR traffic is described.Now, the dispatching priority of this terminal is arranged on after all first differences are greater than the first terminal of zero by base station, first to carry out interface-free resources scheduling to first terminal, ensures that the GBR traffic of first terminal is normally carried out.Wherein, first terminal is the terminal needing to carry out interface-free resources scheduling.
210, carrying out after interface-free resources dispatched to all first terminals, base station judges whether to have available interface-free resources.
If GBR data volume Data_GBR is between maximum amount of data Data_Max and minimum data amount Data_Min, illustrate that the GBR traffic of this terminal has reached this default GBR speed, and do not exceed this MBR preset, namely base station is that this GBR traffic of terminal has distributed enough interface-free resources, can ensure the normal transmission of GBR traffic.
Further, all first differences are greater than zero first terminal and the unsatisfied terminal of GBR carry out after interface-free resources dispatched, base station can judge whether have available interface-free resources in scheduling TTI, if judged result is yes, base station performs step 211; If judged result is no, base station performs step 212.
211, base station is the corresponding interface-free resources of authorization terminal according to the GBR data volume to be passed obtained from the BSR of terminal to report.
When judging to have available interface-free resources, in order to utilize interface-free resources better, interface-free resources can be used for terminal distribution in base station, thus improves data transmission efficiency, improves the utilance of interface-free resources.
Be the corresponding interface-free resources detailed process of authorization terminal about base station according to the GBR data volume to be passed obtained from the BSR of terminal to report, see the record of related content, can repeat no more herein.
212, base station has been the interface-free resources of authorization terminal in current period maintenance.
If judge that not there is available interface-free resources, base station in current period no longer to the more interface-free resources of authorization terminal.And the transmission rate required for GBR traffic of now this terminal reaches default GBR and do not exceed default MBR, it has been the interface-free resources of authorization terminal that base station can maintain, and can send data to make terminal in the interface-free resources of having authorized to base station.
In the present embodiment, the maximum amount of data corresponding by MBR in the setting unit cycle of base station terminal in advance and minimum data amount corresponding to GBR, when in current period, the GBR data volume of terminal actual transmissions is lower than minimum data amount, interface-free resources scheduling is carried out to this terminal in base station, and the GBR data volume in current period is when being between maximum amount of data and minimum data amount, after ensureing the transmission rate required for all GBR traffic, when having available interface-free resources, interface-free resources scheduling can be carried out further to terminal, not only reduce scheduling times, decrease taking CCE resource, and make use of remaining interface-free resources fully, the throughput of raising system.
