Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear
Chu, it is fully described by.
Embodiment one
The embodiment of the present invention provides a kind of resource regulating method, applied to the ground surface end of Satellite Communication System, such as
Shown in Fig. 1, including：
Step 101, the data volume for obtaining data to be dispatched.
Example, when terminal is carried out data transmission using Satellite Communication System, it is transmitted if desired
When data volume is larger, the data for needing to transmit can be divided into multiple packets, according to the form of packet
It is transmitted, is reconfigured after arriving at successively, therefore the data to be dispatched can be a data
Bag, the size of the packet is the data volume of data to be dispatched.
Step 102, the data volume according to the data to be dispatched, the frame of data to be dispatched described in selection scheduling
Structure.
Example, if the data volume of data to be dispatched is larger, long-frame structure can be selected described as scheduling
The frame structure of data to be dispatched, because long-frame structure is smaller than the frame headers overhead of short frame structure, i.e. long-frame structure
Significant character utilization rate is higher, and long frame is higher than the spectrum efficiency of short frame in the case of identical MCS, therefore
The bandwidth availability ratio of system can be improved as the frame structure of the scheduling data to be dispatched using long-frame structure；
If the data volume of data to be dispatched is smaller, short frame structure can be selected as the scheduling data to be dispatched
Frame structure, short frame frame length is a quarter of long frame frame length under being configured due to same band, therefore uses short frame
Structure can improve the dispatching flexibility of system as the frame structure of the scheduling data to be dispatched.
Step 103, the frame structure according to selection, the scheduling data to be dispatched.
Example, long-frame structure and short frame structure can support a variety of MCS, such as QPSK
(Quadrature Phase Shift Keyin, QPSK), 8 phase-shift keyings (8 Phase Shift Keying,
8PSK), 16 amplitude-phase shift keyings (16 Amplitude Phase Shift Keying, 16APSK) or 32APSK.
Different MCS and different code check (Code Rates, CR) combinations can obtain a variety of different modulation and compile
Code mode, every kind of modulation coding mode has corresponding signal to noise ratio demodulation threshold, and supports adaptive coding and modulating
(Adaptive Coding and Modulation, ACM), constant code and modulation (Constant Coding and
Modulation, CCM) two kinds of scheduling methods, wherein ACM is more more flexible than CCM scheduling method, more suitable
With the changeable application scenarios of signal environment, system bandwidth utilization rate can be effectively improved, and CCM is dispatched
Pattern is relatively guarded, and reliability is high, and bandwidth availability ratio is low.It is determined that data to be dispatched described in scheduling
After frame structure, any one mode of ACM or CCM can be selected to dispatch the data to be dispatched.
So, due to can each wait to dispatch according to the data volumes of each data to be dispatched, selection scheduling
The frame structure of data, when when the data volume of scheduling data is larger, can select to treat described in long-frame structure scheduling
Dispatch data；When the data volume for dispatching data is smaller, can select short frame structure dispatch described in wait to dispatch
Data, realize the dynamic select of frame structure, improve the bandwidth availability ratio and dispatching flexibility of whole system.
Optionally, in the data volume according to the data to be dispatched, the frame of data to be dispatched described in selection scheduling
During structure, it can determine whether the data volume of the data to be dispatched is more than or equal to the number of long-frame structure first
According to block.If the data volume of the data to be dispatched is more than or equal to the data block of long-frame structure, long frame knot is selected
Structure is used as the frame structure for dispatching the data to be dispatched；If the data volume of the data to be dispatched is less than long frame knot
The data block of structure, selects short frame structure as the frame structure of the scheduling data to be dispatched.
Example, it can be judged on the basis of the data block of long-frame structure, if the data to be dispatched
Data volume is more than or equal to the data block of long-frame structure, illustrates that the data volume of data to be dispatched is larger, and short frame
The remaining capacity for carrying data is smaller after the beginning of frame pin is removed in structure, if entered using short frame structure
Row scheduling, it may be necessary to short frame structure it is more, cause the bandwidth availability ratio of system relatively low, therefore can select
Long-frame structure is selected to be scheduled the data to be dispatched.If the data volume of the data to be dispatched is less than long frame
The data block of structure, illustrates that the data volume of data to be dispatched is smaller, and the frame length of long-frame structure is longer, if
It is scheduled using long-frame structure, in fact it could happen that the data volume of data to be dispatched, which is less than long frame, can carry data appearance
The situation of amount, now also needs to after the remaining capacity of wait other data occupancy, can just carry out data transmission,
Cause the dispatching flexibility of system relatively low, therefore the scheduling data to be dispatched can be used as using short frame structure
Frame structure.
Optionally, in the data volume according to the data to be dispatched, the frame of data to be dispatched described in selection scheduling
During structure, it can also determine whether the data volume of the data to be dispatched is more than or equal to short frame structure first
Data block.If the data volume of the data to be dispatched is more than or equal to the data block of short frame structure, long frame is selected
Structure is used as the frame structure for dispatching the data to be dispatched；If the data volume of the data to be dispatched is less than short frame
The data block of structure, selects short frame structure as the frame structure of the scheduling data to be dispatched.
Example, it can also be judged on the basis of the data block of short frame structure, if the data to be dispatched
Data volume be more than or equal to the data block of short frame structure, illustrate that the data volume of data to be dispatched is larger, and short
The remaining capacity for carrying data is smaller after the beginning of frame pin is removed in frame structure, if using short frame structure
It is scheduled, it may be necessary to multiple short frame structures, causes the bandwidth availability ratio of system relatively low, therefore can select
Long-frame structure is selected to be scheduled the data to be dispatched.If the data volume of the data to be dispatched is less than short frame
The data block of structure, illustrates that the data volume of data to be dispatched is smaller, and the frame length of long-frame structure is longer, if
It is scheduled using long-frame structure, in fact it could happen that the data volume of data to be dispatched, which is less than long frame, can carry data appearance
The situation of amount, now also needs to after the remaining capacity of wait other data occupancy, can just carry out data transmission,
Cause the dispatching flexibility of system relatively low, therefore the scheduling data to be dispatched can be used as using short frame structure
Frame structure.
Further, before the data volume for obtaining data to be dispatched, it can also wait to dispatch according to
The type of data, it is determined that the MCS of the data to be dispatched.
Example, the type of the data to be dispatched can be divided into broadcast data or unicast data, the broadcast
Data are the data that the whole network is sent, it is necessary to which each terminal can be received in network, therefore can be selected
The MCS of lowest-order is transmitted；The unicast data is the data that network individually issues some terminal.
The availability of frequency spectrum can be improved because the MCS using high-order sends data, therefore is generally tended to
The MCS of higher-order is selected in, but signal to noise ratio current to terminal the more MCS of high-order requires higher, therefore
If when it is unicast data to dispatch data, the current signal to noise ratio of receiving terminal can be determined first, then basis
Signal to noise ratio selects suitable MCS, and the MCS of higher-order can be selected as far as possible, the spectrum utilization of network is improved
Rate.
Optionally, in the type according to the data to be dispatched, it is determined that it is described when the MCS of data is dispatched,
If the type of the data to be dispatched is delay sensitive types of broadcast data, it is determined that the data to be dispatched
MCS is the first MCS；If the type of the data to be dispatched is non-delay sensitive types of broadcast data, really
The MCS of the fixed data to be dispatched is the 2nd MCS；If the type of the data to be dispatched is unicast data
Type, the MCS of data to be dispatched according to being determined the signal to noise ratio of the data to be dispatched.
Example, in order to improve the flexibility of scheduling, broadcast data and unicast data can again be refined
Classification, is divided into delay sensitive broadcast data, non-delay sensitive broadcast data, delay sensitive unicast data, non-
Four kinds of data types of delay sensitive unicast data.Wherein, delay sensitive broadcast data refers to non-to delay requirement
Often high broadcast data, mainly requires high broadcast data etc., example including protocol signaling and propagation delay time
Such as L2S and to the higher HTTP live streaming medias of delay requirement (HTTP Live Streaming, HLS)
Signaling data；The non-delay sensitive broadcast data refers to the broadcast data not high to delay requirement, main bag
Include upper layer application broadcast signaling and propagation delay time requires low broadcast data, for example, not high to delay requirement
HLS signaling datas；The delay sensitive unicast data refers to the unicast data high to delay requirement, mainly
High data are required including upper layer application unicast signaling and voice application associated time delays, for example, using voice
Related data；The non-delay sensitive unicast data refers to the unicast data low to delay requirement, mainly includes
Upper layer application common application unicast data.
If the type of data to be dispatched be delay sensitive types of broadcast data, illustrate the data needs to be dispatched and
When send, and ensure that each terminal in network can be received, therefore default first can be selected
MCS is transmitted, and the first MCS can be the MCS of lower-order；If the class of the data to be dispatched
Type is non-delay sensitive types of broadcast data, illustrates that the data to be dispatched, can not to the less demanding of time delay
Send in time, but be also required to ensure that each terminal in network can be received, therefore can select pre-
If the 2nd MCS be transmitted, the 2nd MCS can be lower-order MCS；In practical application,
First MCS and the 2nd MCS can be configured as the case may be, the first MCS
Can be with identical with the 2nd MCS, can also be different, the embodiment of the present invention is not limited this.If institute
The type for stating data to be dispatched is unicast data, regardless of whether be delay sensitive, can be according to number to be dispatched
According to signal to noise ratio determine the MCS of the data to be dispatched.
Further, in the type of data to be dispatched described in the basis, it is determined that the tune of the data to be dispatched
Before coding mode MCS processed, multiple data to be sent can also be obtained first, it is determined that each number to be sent
According to type, then according to the type of each data to be sent, it is determined that each data to be sent
Priority, and then according to the priority of each data to be sent, the current data to be dispatched of selection.
Example, because data interaction is more in satellite communication network, the same time is likely to be received many numbers
Be transmitted according to bag needs, and the type difference of each packet, some be it is higher to delay requirement,
Some are not high to delay requirement, if be transmitted in order, may delay many packets when
Prolong, it is possible to which, according to the type of data, priority of disposing order is transmitted according to priority orders.Assuming that
Data can be divided into delay sensitive broadcast data, non-delay sensitive broadcast data, delay sensitive unicast data,
Non- four kinds of data types of delay sensitive unicast data, the priority orders of four kinds of data types can be time delay
Sensitive broadcast data, non-delay sensitive broadcast data, delay sensitive unicast data, non-delay sensitive unicast number
According to.Wherein, the priority of broadcast data be higher than unicast data priority, delay sensitive class data it is preferential
Level is higher than the priority of non-delay sensitive class data.Then current data to be dispatched are selected according to priority.
For example, receive needs to be sent to multiple data to be sent of terminal first, it is then determined that each data to be sent
Type, and then each data priority to be sent, example can be determined according to the type of each data to be sent
Such as, if data to be sent are delay sensitive broadcast data, highest priority；If data to be sent are
Non- delay sensitive unicast data, then priority is minimum.After the priority of each data to be sent is determined,
Can according to data to be sent priority, determine current data to be dispatched.
The embodiment of the present invention provides a kind of resource regulating method, including：Obtain the data volume of data to be dispatched；
According to the data volume of the data to be dispatched, the frame structure of data to be dispatched described in selection scheduling；According to selection
Frame structure, the scheduling data to be dispatched.Compared to prior art, due to that can wait to dispatch according to each
The data volume of data, the frame structure of each data to be dispatched of selection scheduling, when data to be dispatched data volume compared with
When big, the long-frame structure scheduling data to be dispatched can be selected；When wait dispatch data data volume it is smaller when,
The short frame structure scheduling data to be dispatched can be selected, the dynamic select of frame structure is realized, improves whole
The bandwidth availability ratio and dispatching flexibility of individual system.
Embodiment two
The embodiment of the present invention provides a kind of resource regulating method, applied to the ground surface end of Satellite Communication System, institute
The interface that ground surface end is Satellite Communication System and ground public network is stated, terminal can also be come in and gone out by ground surface end and be defended
Star system formation link, the ground surface end can also include ground satellite control centre, and its tracking, remote measurement
And command station.As shown in Fig. 2 the resource regulating method includes：
Step 201, the multiple data to be sent for needing to be sent to terminal of reception, perform step 202.
In practical application, data interaction is more in satellite communication network, and the same time may have multiple packets
Need to be transmitted, therefore multiple data to be sent can be obtained in a period.
Step 202, the type for determining each data to be sent, perform step 203.
Example, data to be sent can be divided into delay sensitive broadcast data, non-delay sensitive broadcast data,
Delay sensitive unicast data, four kinds of data types of non-delay sensitive unicast data.
Step 203, the type according to each data to be sent, it is determined that the priority of each data to be sent,
Perform step 204.
Example, the priority orders of above-mentioned four kinds of data types can be delay sensitive broadcast data, when non-
Prolong sensitive broadcast data, delay sensitive unicast data, non-delay sensitive unicast data.Wherein, broadcast data
Priority be higher than the priority of unicast data, the priority of delay sensitive class data is higher than non-delay sensitive class
The priority of data.Then current data to be dispatched are selected according to priority.Then can be according to be sent
The type of data, it is determined that the priority of each data to be sent, if for example, data to be sent are delay sensitive
Broadcast data, then highest priority；If data to be sent are non-delay sensitive unicast data, priority is most
It is low.
Step 204, the priority according to each data to be sent, the current data to be dispatched of selection are performed
Step 205.
Example, after the priority of each data to be sent is determined, it can be selected according to priority
It is currently needed for the data to be dispatched being scheduled.It is time delay that the higher type of priority can for example be selected first
Then the data to be sent of sensitive broadcast data select priority to take second place as the data to be dispatched of current scheduling
Type be used as the data to be dispatched dispatched next time for non-delay sensitive broadcast data data to be sent.Specifically
Selecting sequence can be configured according to actual conditions, the embodiment of the present invention is not limited this.
Step 205, the type according to the data to be dispatched, it is determined that the MCS of the data to be dispatched, holds
Row step 206.
Example, although the MCS of low order can cause the availability of frequency spectrum relatively low, but it ensure that network
Each interior terminal can be received；Although the MCS of high-order can improve the availability of frequency spectrum, right
The current signal to noise ratio of terminal requires higher, and the terminal of signal difference possibly can not be received, therefore in practical application,
Can according to the type of data to be dispatched determine described in data to be dispatched MCS.If the type of data to be dispatched
For delay sensitive types of broadcast data, default first MCS can be selected to be transmitted, the first MCS
Can be the MCS of lower-order；If the type of the data to be dispatched is non-delay sensitive types of broadcast data,
Default 2nd MCS can be selected to be transmitted, the 2nd MCS can be the MCS of lower-order；It is real
In the application of border, the first MCS and the 2nd MCS can be configured as the case may be, described
First MCS and the 2nd MCS can be with identical, can also be different, and the embodiment of the present invention is not limited this
It is fixed.If the type of the data to be dispatched is unicast data, regardless of whether be delay sensitive, can basis
The signal to noise ratio of data to be dispatched determines the MCS of the data to be dispatched.
Step 206, the data volume for obtaining the data to be dispatched, perform step 207.
Whether step 207, the data volume of the determination data to be dispatched are more than or equal to the data of long-frame structure
Block；When described when the data volume for dispatching data is more than or equal to the data block of long-frame structure, step 208 is performed；
When described when the data volume for dispatching data is less than the data block of long-frame structure, step 209 is performed.
Example, it can be judged on the basis of the data block of long-frame structure, if the data to be dispatched
Data volume is more than or equal to the data block of long-frame structure, illustrates that the data volume of data to be dispatched is larger, now may be used
To select long-frame structure to be scheduled the data to be dispatched.If the data volume of the data to be dispatched is less than
The data block of long-frame structure, illustrates that the data volume of data to be dispatched is smaller, can now be made using short frame structure
For the frame structure of the scheduling data to be dispatched.
Step 208, the data to be dispatched are dispatched using long-frame structure and the MCS of determination, this flow terminates.
Example, if data to be dispatched are delay sensitive broadcast data, and data volume is more than or equal to long frame
The data block of structure, can select long-frame structure and the first MCS to be scheduled；If data to be dispatched are
Non- delay sensitive broadcast data, and data volume is more than or equal to the data block of long-frame structure, can select long frame
Structure and the 2nd MCS are scheduled；If data to be dispatched are unicast data, and data volume is more than or waited
In the data block of long-frame structure, long-frame structure and the MCS determined according to signal to noise ratio can be selected to be scheduled.
Step 209, the data to be dispatched are dispatched using short frame structure and the MCS of determination.
Example, if data to be dispatched are delay sensitive broadcast data, and data volume is less than long-frame structure
Data block, can select short frame structure and the first MCS to be scheduled；If data to be dispatched are non-time delay
Sensitive broadcast data, and data volume is less than the data block of long-frame structure, can select short frame structure and second
MCS is scheduled；If data to be dispatched are unicast data, and data volume is less than the data block of long-frame structure,
Short frame structure and the MCS determined according to signal to noise ratio can be selected to be scheduled.
The embodiment of the present invention provides a kind of resource regulating method, compared to prior art, due to can be according to every
The data volume of individual data to be dispatched, the frame structure of each data to be dispatched of selection scheduling, when data to be dispatched
When data volume is larger, the long-frame structure scheduling data to be dispatched can be selected；When the data of data to be dispatched
When amount is smaller, the short frame structure scheduling data to be dispatched can be selected, the dynamic select of frame structure is realized,
Improve the bandwidth availability ratio and dispatching flexibility of whole system.
