A kind of method for running on above computer terminal is provided in the present embodiment, and Fig. 3 is
A kind of flow chart of the dispatching method of ascending resource according to embodiments of the present invention, as shown in figure 3,
The flow comprises the following steps：
Step S302, network side equipment obtain the Buffer Status Report BSR institutes that terminal reports
The BSR types of category.
Alternatively, i.e., the embodiment of the present application provide ascending resource dispatching method, can be applicable
It is certainly right in plurality of communication systems, such as the communication system such as LTE, WIFI, WCDMA
It is equally applicable in the larger Interactive Satellite communication system of time delay of eating dishes without rice or wine, for the latter, now

Buffer area data volume, obtain effective buffer data volume；Wherein, the effective buffer data
Measure for indicating that the network side equipment needs the resource of the ascending resource for the terminal distribution
Amount；
Alternatively, when it is determined that the type of the BSR is absolute BSR, the effectively buffering
Area's data volume is that definitely BSR absolute magnitude and the network side equipment have been the end
End distribution but the difference of the stock number of Pending The Entry Into Force, specifically, can be counted by formula 1
Calculate：
Formula 1：dataEffectively=dataDefinitely-dataDistribution；
Wherein, dataEffectivelyRepresent effective buffer data volume, dataDefinitelyRepresent absolute BSR's
Absolute magnitude, and dataDistributionRepresent the buffering area that network side equipment is terminal distribution but Pending The Entry Into Force
Data volume.
Wherein, absolute BSR absolute magnitude is used to represent buffering corresponding with the definitely BSR
Area's data volume (i.e. the data volume size of buffering area storage).For example, 2500 words of terminal buffers
The buffer area data volume of section, and network side equipment is reported by way of absolute BSR, that
Absolute BSR absolute magnitude is the buffer data for 2500 bytes for reporting network side equipment
Amount.
Wherein, network side equipment is terminal distribution but the buffer area data volume of Pending The Entry Into Force is used for table
Show that network side equipment is already allocated to the terminal, and absolute BSR is reported in the terminal
When, the stock number for the ascending resource that the terminal is also not received by.For example, terminal is current
Before the absolute magnitude for reporting absolute BSR, the buffer area data volume of 2500 bytes has also been reported.
The buffer area data volume for 2500 bytes that network side equipment can report before is terminal distribution
The stock number of ascending resource.And when terminal reports the absolute magnitude of the BSR, terminal is but also not
Receive the stock number of the ascending resource of above-mentioned 2500 byte.So, above-mentioned network side equipment point
The stock number of the ascending resource for 2500 bytes matched somebody with somebody be network side equipment be terminal distribution but not
The buffer area data volume to come into force.
Alternatively, when it is determined that the type of the BSR is increment BSR, the effectively buffering
Area's data volume be increment and the terminal of the increment BSR existing buffer area data volume it
With calculated by formula 2：
Formula 2：dataEffectively=dataIncrement+dataIt is existing
Wherein, dataIncrementFor representing increment BSR increment, and dataIt is existingExpression has been delayed
Rush area's data volume.
Wherein, increment BSR increment is used to represent buffering area corresponding with the increment BSR
Data volume.For example, the terminal last time reports increment BSR to current time, terminal buffer
Data volume adds 2500 bytes, and reports network side equipment by way of increment BSR,
So increment BSR increment is the buffer data for 2500 bytes for reporting network side equipment
Amount.
Wherein, above-mentioned existing buffer area data volume is used to represent to report the increment in the terminal
Before BSR, the buffer area data volume for the terminal that the network side equipment is safeguarded.It is specific and
Speech, if this reports increment BSR to report BSR for the first time for terminal, then buffered
Area's data volume is 0.And if it is not to report BSR for the first time that this, which reports increment BSR, that
Existing buffer area data volume is before this reports increment BSR, and network side equipment is eventually
The buffer area data volume for the terminal that network side equipment is safeguarded after end distribution ascending resource.For example, eventually
End has also reported the number of buffer of 2500 bytes before increment BSR increment is currently reported
According to amount.After the ascending resource of above-mentioned 2500 byte is distributed to terminal by network side equipment, net
The buffer area data volume for the terminal that network side apparatus is safeguarded is 0 byte.So has buffer data
Measure as 0 byte.
Step S306, the network side equipment are described according to the effective buffer data volume
Ascending resource described in terminal distribution.
Provide in the present embodiment another kind run on above computer terminal or with it is upper
The method for stating the mobile terminal of terminal similar structures, Fig. 4 are according to embodiments of the present invention
Another ascending resource dispatching method flow chart, as shown in figure 4, the flow include figure
In 3 beyond step S302-S306, in addition to：
Step S402, according to the stock number of the ascending resource, update the network side equipment
The buffer area data volume for the terminal safeguarded.
Specifically, network side equipment can pass through formula 3 after the stock number of distribution ascending resource
It is updated the buffer area data volume of the terminal.
Formula 3：dataRenewal=dataEffectively-resourceDistribution；
Wherein, dataRenewalThe buffering area for the terminal safeguarded due to representing the network side equipment after updating
Data volume, and resourceDistributionFor representing network side equipment for the ascending resource of terminal distribution
Stock number.
Specifically, the buffer area data volume effect of the terminal after renewal is to represent network side equipment
Whether using whole buffer area data volumes that terminal reports as the up money for the terminal distribution
Source.If difference is 0, it can be whole buffering areas that terminal reports to prove network side equipment
Data volume distributes ascending resource；And if when difference is not 0, then prove there is part terminal to report
Buffer area data volume do not distribute ascending resource by network side equipment.Now, network side equipment
The stock number of ascending resource can be sent to terminal.
In addition, following 3 kinds of scenes are also provided in the present embodiment in order to understand the present embodiment.Tool
Body is as follows：
It is pointed out that 2 terminals are only described among following scene reports BSR, and
Among practical application, terminal repeatedly can also report BSR to network side equipment.

It is absolute BSR to determine BSR types.And obtain absolute BSR=5000 bytes.Due in acquisition
Preceding not obtain other BSR, network side equipment is determined as the upper of terminal distribution but Pending The Entry Into Force
The stock number of row resource is 0.According to formula 1, effective buffer number that network side equipment obtains
It is 5000-0=5000 bytes according to amount.Then, network side equipment is the slow of terminal more new terminal
Area's data volume is rushed to be 5000 bytes and be the ascending resource of the byte of terminal distribution 5000.Last root
According to formula 3, the buffer area data volume for the terminal that renewal network side equipment is safeguarded is 0.
4.t3 moment, network side equipment get terminal after the BSR that the t1 moment reports, really
It is increment BSR to determine BSR types, and obtains increment BSR=1000 bytes, is reported at this
Before, terminal has reported absolute BSR=5000 bytes and network side equipment is terminal distribution
The ascending resource of 5000 bytes, it is thus determined that existing buffer area data volume is 0.According to formula

The buffer area data volume of terminal is 5000 bytes and is the ascending resource of the byte of terminal distribution 5000.
The buffer area data volume for the terminal finally safeguarded according to formula 3, renewal network side equipment is 0.
4.t3 moment, network side equipment get terminal after the BSR that the t0 moment reports, really
It is absolute BSR to determine BSR types.And obtain absolute BSR=6000 bytes.Due to now
Terminal does not receive the ascending resource for 5000 bytes distributed at the t0 moment, therefore network also
Side apparatus has been the byte of stock number=5000 of terminal distribution but the ascending resource of Pending The Entry Into Force.Root
According to formula 1, it is 6000-5000=1000 bytes that network side equipment, which obtains effective buffer data volume,.
Then, network side equipment is the upper of the byte of terminal distribution 1000 according to effective buffer data volume
Row resource.The buffer data for the terminal finally safeguarded according to formula 3, renewal network side equipment
Measure as 0.
5.t4 moment, terminal receive the ascending resource of 5000 bytes of network side equipment distribution.
And the upstream data of 5000 bytes is sent to network side equipment.Now, the buffering area of terminal
