Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
It is one of the flow chart of data transmission method provided in an embodiment of the present invention referring to Fig. 1, Fig. 1, as shown in Figure 1, this
Embodiment provides a kind of data transmission method, is applied to terminal, comprising the following steps:
Step 101, the uplink parameter for determining the terminal.
Uplink parameter can be the total amount of data in terminal uplink caching, the upstream data of target object in uplink caching
One or more of data volume or the time delay of target object.Target object can be regarded as the application of terminal, for example, game
Using, Video Applications, live streaming application etc. to the demanding application of time delay.
If step 102, the uplink parameter meet preset condition, the part of target object in the uplink caching is abandoned
Upstream data, so that the uplink parameter is unsatisfactory for the preset condition.
If uplink parameter includes the data volume of the upstream data of target object in uplink caching, on preset condition may include
The data volume of the upstream data of target object is greater than the first data-quantity threshold in row caching；If uplink parameter includes that terminal uplink is slow
Total amount of data in depositing, then preset condition may include that the total amount of data in terminal uplink caching is greater than the second data-quantity threshold；If
Uplink parameter includes the time delay of target object, then preset condition may include that the time delay of target object is greater than time threshold.Default item
Part is regarded as influencing the condition of the data transmission delay of target object.
In abandoning uplink caching when the part upstream data of target object, it can preferentially abandon and be stored in uplink caching at first
In data.For example, the time sequencing in uplink caching is stored according to the upstream data of target object, from oldest stored upper
Data in row caching start successively to abandon, until uplink parameter is unsatisfactory for preset condition.
In the present embodiment, the part upstream data of target object, it can be understood as, the institute of target object in uplink caching
There is a part of upstream data in upstream data, it is understood that be all upstream datas of target object in uplink caching.
When network is in weaker environment, uplink caching will appear data accumulation, when network improves, although uplink authorization
It gets higher, but the data accumulated in still needing to cache uplink are first sent, and are then transmitted again to new data.Number
When according to accumulating more, it is more to send the time that the data accumulated in uplink caching need.In the present embodiment, by abandoning uplink
The part upstream data of target object in caching can reduce the data that terminal sends the upstream data accumulated in uplink caching
Amount, to reduce the time that terminal sends the data accumulated in uplink caching, to reduce the data transmission delay of target object.?
That is uplink caching is easy to appear the case where accumulating more data volume in the case where network signal intensity is unstable, pass through
The part upstream data for abandoning target object in uplink caching, can reduce the data transmission delay of target object.
In the embodiment of the present invention, above-mentioned terminal can for mobile phone, tablet computer (Tablet Personal Computer),
Laptop computer (Laptop Computer), personal digital assistant (personal digital assistant, abbreviation PDA),
Mobile Internet access device (Mobile Internet Device, MID) or wearable device (Wearable Device) etc..
The data transmission method of the embodiment of the present invention determines the uplink parameter of the terminal；If the uplink parameter meets
Preset condition then abandons the part upstream data of target object in the uplink caching, so that the uplink parameter is unsatisfactory for
The preset condition, in this way, can reduce terminal by the part upstream data for abandoning the target object in uplink caching and send
The data volume for the upstream data accumulated in row caching, to reduce the time that terminal sends the data accumulated in uplink caching, thus
Reduce the data transmission delay of target object.
When the uplink parameter difference of use, corresponding preset condition is different, is exemplified below several implementations to above-mentioned
Step 102 is illustrated.
The first implementation: including the first application of the terminal in the target object, and the uplink parameter includes
In the case where the data volume of the upstream data of first application described in the uplink caching and the total amount of data of uplink caching,
Above-mentioned steps 102, comprising:
If the data volume of the upstream data of the first application described in the uplink caching is greater than the first data-quantity threshold, and institute
The total amount of data for stating uplink caching is greater than the second data-quantity threshold, then abandons the part of the first application described in the uplink caching
Upstream data, so that the data volume of the remaining upstream data of the first application described in uplink caching is no more than first number
According to amount threshold value, and/or, so that the total amount of data of uplink caching is not more than the second data-quantity threshold；
Alternatively,
If the data volume of the upstream data of the first application described in the uplink caching is greater than the first data-quantity threshold, and institute
The total amount of data for stating uplink caching is greater than the second data-quantity threshold, and triggering uplink maximum retransmits, to empty the uplink caching.
Specifically, the data volume that preset condition is the upstream data of the first application described in uplink caching is greater than first
Data-quantity threshold, and the total amount of data of uplink caching is greater than the second data-quantity threshold.Second data-quantity threshold can be according to reality
Border situation is configured, it is not limited here.Second data-quantity threshold is greater than the first data-quantity threshold.Second data-quantity threshold can
It is considered that uplink caches acceptable maximum data cumulant, it is acceptable most that the first data-quantity threshold is regarded as the first application
Small data quantity.The data volume of the upstream data of first application described in caching when uplink is greater than the first data-quantity threshold, and described
When the total amount of data of uplink caching is greater than the second data-quantity threshold, the upstream data in uplink caching is handled.
When upstream data in caching to uplink is handled, including two kinds of processing modes.The first processing mode are as follows:
The part upstream data of the first application described in the uplink caching is abandoned, so that the first application described in uplink caching
The data volume of remaining upstream data is not more than first data-quantity threshold, and/or, so that the total amount of data of uplink caching
No more than the second data-quantity threshold.By abandoning the part upstream data of the first application in uplink caching, terminal hair can be reduced
The data volume for the upstream data accumulated in row caching is served, to reduce the time that terminal sends the data accumulated in uplink caching,
To reduce the data transmission delay of the first application.For application higher for delay requirement, it can be subtracted using present treatment mode
Few time delay, improves user experience.
The part upstream data of first application, it can be understood as, in uplink caching in all upstream datas of the first application
A part of upstream data, it is understood that be, uplink caching in first application all upstream datas.
Second of processing mode are as follows: triggering uplink maximum retransmits, to empty the uplink caching.Trigger uplink maximum weight
It passes, may make terminal from Radio Link Failure (Radio Link Failure, abbreviation RLF) is determined, rebuild into Radio Link.
Terminal is rebuild by Radio Link, can complete emptying for uplink caching.After emptying, the residue of the first application in uplink caching
The data volume of upstream data is 0, and the total amount of data of uplink caching is 0, still meets the surplus of the first application described in uplink caching
The total amount of data that the data volume of remaining upstream data is cached no more than first data-quantity threshold or the uplink is no more than the
Two data-quantity thresholds.
It in second of processing mode, is retransmitted from triggering uplink maximum, so that terminal is from judgement Radio Link Failure to complete
It is rebuild at Radio Link, needs tens to several hundred milliseconds, there are certain risks, are preferably applied to network and fluctuation in short-term occur
Afterwards, the case where data in needing to cache uplink are restored rapidly.By emptying uplink caching, it is slow that terminal transmission uplink can be reduced
The data volume of the upstream data of middle accumulation is deposited, to reduce the time that terminal sends the data accumulated in uplink caching, to reduce
The data transmission delay of first application.
Second of implementation: including the first application of the terminal in the target object, and the uplink parameter includes
In the case where the data volume of the upstream data of first application described in the uplink caching and the time delay of first application,
Above-mentioned steps 102, comprising:
If the data volume of the upstream data of the first application described in the uplink caching is greater than the first data-quantity threshold, and institute
Time delay is stated greater than time threshold, then the part upstream data of the first application described in the uplink caching is abandoned, so that described
The data volume of the remaining upstream data of first application described in uplink caching is not more than first data-quantity threshold, and/or, make
It obtains the time delay and is not more than the time threshold；
Alternatively,
If the data volume of the upstream data of the first application described in the uplink caching is greater than the first data-quantity threshold, and institute
Time delay is stated greater than time threshold, triggering uplink maximum retransmits, to empty the uplink caching.
Specifically, the time delay of the first application can be from transmission control protocol (the Transmission Control of terminal
Protocol, abbreviation TCP) or Internet protocol (Internet Protocol, abbreviation IP) (can be regarded as TCP/IP layer) layer in
It obtains.In the second implementation, uplink parameter not only includes the data volume of the upstream data of the first application in uplink caching,
It further include the time delay of the first application.The data volume of the upstream data of the first application described in uplink caching is greater than the first number
According to amount threshold value, and the time delay is handled the upstream data in uplink caching greater than in the case where time threshold.
When upstream data in caching to uplink is handled, including two kinds of processing modes.The first processing mode are as follows:
The part upstream data of the first application described in the uplink caching is abandoned, so that the first application described in uplink caching
The data volume of remaining upstream data is not more than first data-quantity threshold, and/or, so that the time delay is not more than the time
Threshold value.
In abandoning uplink caching when the part upstream data of the first application, it can preferentially abandon and be stored in uplink caching at first
In data.For example, the time sequencing in uplink caching is stored according to the upstream data of the first application, from oldest stored upper
Row caching in data start successively to abandon, until uplink caching described in first application remaining upstream data data volume not
Greater than first data-quantity threshold, and/or, so that the time delay is not more than the time threshold.
By abandoning the part upstream data of the first application in uplink caching, terminal can be reduced and sent in uplink caching and tired out
The data volume of the upstream data of the first long-pending application, to reduce the time that terminal sends the data accumulated in uplink caching, thus
Reduce the data transmission delay of the first application.For application higher for delay requirement, when can be reduced using present treatment mode
Prolong, improves user experience.
The part upstream data of first application, it can be understood as, in uplink caching in all upstream datas of the first application
A part of upstream data, it is understood that be, uplink caching in first application all upstream datas.
Second of processing mode are as follows: triggering uplink maximum retransmits, to empty the uplink caching.Trigger uplink maximum weight
It passes, may make terminal from Radio Link Failure (Radio Link Failure, abbreviation RLF) is determined, rebuild into Radio Link.
Terminal is rebuild by Radio Link, can complete emptying for uplink caching.After emptying, the residue of the first application in uplink caching
The data volume of upstream data is 0, and the data volume for still meeting the remaining upstream data of the first application described in uplink caching is little
In the condition of first data-quantity threshold.
It in second of processing mode, is retransmitted from triggering uplink maximum, so that terminal is from judgement Radio Link Failure to complete
It is rebuild at Radio Link, needs tens to several hundred milliseconds, there are certain risks, are preferably applied to network and fluctuation in short-term occur
Afterwards, the case where data in needing to cache uplink are restored rapidly.By emptying uplink caching, it is slow that terminal transmission uplink can be reduced
The data volume of the upstream data of middle accumulation is deposited, to reduce the time that terminal sends the data accumulated in uplink caching, to reduce
The data transmission delay of first application.
It retransmits from triggering uplink maximum, so that terminal is rebuild Zi judgement Radio Link Failure to Radio Link is completed, needs
Tens arrive several hundred milliseconds, there are certain risk, be preferably applied to after fluctuation in short-term occurs in network, need to cache uplink
Data the case where restoring rapidly.By emptying uplink caching, terminal can be reduced and send the upstream data accumulated in uplink caching
Data volume, the time of data accumulated in uplink caching is sent to reduce terminal, to reduce the data transmission of target object
Time delay.
In caching to uplink, whether there can be the mark of target object to judge whether the data are target by data
The data of object.The mode of realization are as follows: in step 101, determine the uplink parameter of the terminal before, further includes:
Mark is arranged in upstream data for first application；
The upstream data of the first application described in the uplink caching is determined according to the mark.
Specifically, terminal is marked in upstream data of the TCP/IP layer to target object, it is unique for upstream data setting
Mark, terminal can distinguish other upstream datas of the upstream data of target object and terminal according to mark.
In Packet Data Convergence Protocol (Packet Data Convergence Protocol, abbreviation PDCP), radio chains
Circuit control layer agreement (Radio Link Control, abbreviation RLC), FDDI sublayer protocol (Media Access
Control, abbreviation MAC) subpackage processing in, to high level arrive packet, such as find target object mark, then in equivalent layer
In subpackage, the mark of target object is also added.For needing to remove current layer during transmitting toward the packet of low layer transmitting
Transmitted again after the mark of the target object of addition (i.e. data in transmission process, be according to not marker data format into
Row transmitting, when data are in each layer of L2, data be to have existing for the data format of marker, L2 layer including PDCP layers,
Rlc layer and MAC layer).The mark of target object can only be stored in the head (header) of the data of each layer, for example, can be
Head increases marker, this marker may map to target object (i.e. the numerical value with target object of marker are corresponding).Data
In transmission process, terminal can determine whether according to this marker be target object data, determine whether to need to abandon.
Terminal when the upstream data of target object, can determine that the uplink is slow according to the mark in determining uplink caching
The upstream data of first application described in depositing, so that it is determined that the data volume of the upstream data of the first application.Uplink caching is located at MAC
Layer.
Terminal can be determined in the uplink caching by the way that mark is arranged for the upstream data of target object according to the mark
The data volume of the upstream data of first application, further to be determined according to the data volume of the upstream data of the target object
Whether need to abandon data, and when abandoning data, according to the upstream data for determining target object is identified, thus to target object
Upstream data abandoned.
The present invention also provides another kind determine whether be target object data mode.Further, in the determining institute
Before the uplink parameter for stating terminal, further includes:
If the upstream data of first application includes preset service quality rating mark QCI, true according to the QCI
Determine the logic channel for carrying out uplink；
Data in the logic channel are determined as to the upstream data of first application.
Specifically, the upstream data of target object may have distinctive service quality rating mark (QoS Class
Identifier, abbreviation QCI), wherein QoS is service quality (Quality of Service, abbreviation QoS), for example, some
Game data.In the case where the upstream data of target object includes preset QCI, determined according to the QCI for carrying out
The logic channel of row transmission, which is used for transmission the upstream data of target object, at this point, the data in the logic channel
It can be identified as the upstream data of target object, and the data volume in the logic channel be determined as the upper of first application
The data volume of row data.When carrying out data discarding, the data in logical channel buffer are abandoned.That is, passing through
Logic channel can determine the upstream data of target object.Logical channel buffer can be regarded as a part of uplink caching.
When being abandoned to the data in logical channel buffer, it can preferentially abandon and be stored in logical channel buffer at first
Data.For example, data are stored in the time sequencing in logical channel buffer, successively abandoned since the data of oldest stored,
Until uplink parameter is unsatisfactory for preset condition.Alternatively, it is also possible to carry out emptying processing to logic channel, i.e., by logical channel buffer
In data all remove.
In the present embodiment, by abandoning the data in logical channel buffer, line number on the part to abandon target object
According to, the data volume that terminal sends the upstream data accumulated in uplink caching can be reduced, it is tired in terminal transmission uplink caching to reduce
The time of long-pending data, to reduce the data transmission delay of target object.
Terminal also can be by configuring the movement of PDCP packet loss timer (discard timer) Lai Jinhang packet loss, and terminal can needle
To specific application (such as first application) using customized thresholding (i.e. the first data-quantity threshold, and/the second data-quantity threshold) into
Row packet loss, compared to packet loss timer is used, packet loss mode is more flexible.When packet loss timer is configured to infinitely great (infinity)
When, the packet loss behavior of terminal is directly realized according to the packet loss mode in above-mentioned implementation；When packet loss timer is not set
When being set to infinitely great (infinity) (such as 300ms), if in uplink parameter, the time delay of target object is less than the value (300ms),
The effect for improving time delay can be also played using data transmission method of the invention.
As shown in Fig. 2, Fig. 2 is the two of the flow diagram of data transmission method provided in an embodiment of the present invention, such as Fig. 2 institute
Show, Fig. 2 is illustrated by taking low time delay class game as an example.
Step 111, into game, i.e., running game application in terminal.
The upstream data of game application is marked in step 122.Terminal according to the mark of game application (alternatively referred to as
Data Identification), it is marked in data of the TCP/IP layer to game application.During uplink is sent, when these data reach modem
When, it can also be distinguished in modem (can be regarded as L2 layers) with other data.In the subpackage processing of PDCP, RLC, MAC,
To the packet that high level arrives, such as " game data mark " is found, then in the subpackage of equivalent layer, " game data mark is also added.It is right
It is transmitted again after needing to remove " the game data mark " of current layer in the version of transmitting in the packet toward low layer transmitting.Data mark
Knowledge can only be stored in each layer header, need to increase marker in header, this marker may map to some or certain
Class low time delay application.In data transmission procedure, modem can position the data for needing to abandon according to this marker.
Data volume A1 > X and A2 > Y are accumulated in step 133, uplink caching.Pass through the threshold X (of customized setting
Two data-quantity thresholds) and threshold Y (the first data-quantity threshold), wherein X is acceptable maximum data cumulant, and Y is
The acceptable minimum data amount of game application (Y < X).Accumulation data volume is denoted as A1, the data volume of game application accumulation in buffer
It is denoted as A2.In game application operation, if working as A1 > X and A2 > Y because uplink is limited to cause L2 uplink caching (buffer) accumulation
When, go to step 44 execution.
Step 144 identifies and abandons the partial game data in uplink caching.It identifies and abandons beyond threshold
The correspondence game data amount of X.For example, abandoning the game data of oldest accumulated, until A1≤X or A2≤Y, circulation is exited simultaneously
Monitoring buffer is kept to accumulate data volume.
Threshold X and Threshold Y may be provided in terminal projects mode or developer's mode and is adjusted.
Step 155 subsequent is given out a contract for a project again since serial number n.If the data packet of MAC layer is without abandoning, in respective counts
Before being sent according to packet, retransmited after mark (i.e. terminal is identification target object, for the mark of target object addition) need to be removed；If right
The data packet of MAC layer is abandoned, then abandon when, need also accordingly to abandon rlc layer and PDCP layer of packet, and rlc layer with
PDCP packet number keeps continuous, that is, while abandoning corresponding packet, need to record the serial number n of discarding accordingly wrapped, it is subsequent to give out a contract for a project
When need again since serial number n, avoid out-of-order repeating transmission.
As shown in figure 3, Fig. 3 is the three of the flow diagram of data transmission method provided in an embodiment of the present invention, such as Fig. 3 institute
Show, Fig. 3 is illustrated by taking low time delay class game as an example.
The step of difference of Fig. 3 and Fig. 2 is, eliminates label game application data.Game data has distinctive
QCI is carried by corresponding logic channel.When carrying out data discarding, it is only necessary to be directed to the distinctive logic channel of game data
It is abandoned.
Step 211, into game, i.e., running game application in terminal.
Data volume A1 > X and A2 > Y are accumulated in step 222, uplink caching.Pass through the threshold X (of customized setting
Two data-quantity thresholds) and threshold Y (the first data-quantity threshold), wherein X is acceptable maximum data cumulant, and Y is
The acceptable minimum data amount of game application (Y < X).Accumulation data volume is denoted as A1, the data volume of game application accumulation in buffer
It is denoted as A2.In game application operation, if working as A1 > X and A2 > Y because uplink is limited to cause L2 uplink caching (buffer) accumulation
When, go to step 233 execution.
Step 233 recognizes counterlogic channel by corresponding QCI, and loses to the partial data in logic channel
It abandons.
It identifies and abandons the correspondence game data amount beyond threshold X.For example, abandoning the game number of oldest accumulated
According to exiting circulation and keep monitoring buffer accumulation data volume until A1≤X or A2≤Y.
Threshold X and Threshold Y may be provided in terminal projects mode or developer's mode and is adjusted.
Step 244 subsequent is given out a contract for a project again since serial number n.If the data packet of MAC layer is without abandoning, in respective counts
Before being sent according to packet, retransmited after mark (i.e. terminal is identification target object, for the mark of target object addition) need to be removed；If right
The data packet of MAC layer is abandoned, then abandon when, need also accordingly to abandon rlc layer and PDCP layer of packet, and rlc layer with
PDCP packet number keeps continuous, that is, while abandoning corresponding packet, need to record the serial number n of discarding accordingly wrapped, it is subsequent to give out a contract for a project
When need again since serial number n, avoid out-of-order repeating transmission.
Mode shown in the ratio of mode shown in Fig. 3 Fig. 2 is more concise direct, but is limited by some factors: such as opening for double
Game can not identify different game datas, alternatively, not support that particular game corresponds to specific for certain place core net strategies
QCI etc..
As shown in figure 4, Fig. 4 is the four of the flow diagram of data transmission method provided in an embodiment of the present invention, such as Fig. 4 institute
Show, Fig. 4 is illustrated by taking low time delay class game as an example.The difference of Fig. 4 and Fig. 2 is, while considering game data in uplink
The time delay of data volume and game application in caching.
Step 311, into game, i.e., running game application in terminal.
The upstream data of game application is marked in step 322.Terminal according to the mark of game application (alternatively referred to as
Data Identification), it is marked in data of the TCP/IP layer to game application.During uplink is sent, when these data reach modem
When, it can also be distinguished in modem (can be regarded as L2 layers) with other data.In the subpackage processing of PDCP, RLC, MAC,
To the packet that high level arrives, such as " game data mark " is found, then in the subpackage of equivalent layer, " game data mark is also added.It is right
It is transmitted again after needing to remove " the game data mark " of current layer in the version of transmitting in the packet toward low layer transmitting.Data mark
Knowledge can only be stored in each layer header, need to increase marker in header, this marker may map to some or certain
Class low time delay application.In data transmission procedure, modem can position the data for needing to abandon according to this marker.
Step 333, game application time delay T1 > T and A2 > Y.Game time delay T1 can be obtained from TCP/IP.By customized
The threshold T (time threshold) and threshold Y (the first data-quantity threshold) of setting.Buffer game application accumulation
Data volume is denoted as A2.In game application operation, if working as T1 > T because uplink is limited to cause L2 uplink caching (buffer) accumulation
And when A2 > Y, 344 execution are gone to step.
Step 344 identifies and abandons the partial game data in uplink caching, that is, identifies and abandon the game of oldest accumulated
Data exit circulation and keep monitoring buffer accumulation data volume until A1≤X or A2≤Y.
Threshold T and Threshold Y may be provided in terminal projects mode or developer's mode and is adjusted.
Step 355 subsequent is given out a contract for a project again since serial number n.If the data packet of MAC layer is without abandoning, in respective counts
Before being sent according to packet, retransmited after mark (i.e. terminal is identification target object, for the mark of target object addition) need to be removed；If right
The data packet of MAC layer is abandoned, then abandon when, need also accordingly to abandon rlc layer and PDCP layer of packet, and rlc layer with
PDCP packet number keeps continuous, that is, while abandoning corresponding packet, need to record the serial number n of discarding accordingly wrapped, it is subsequent to give out a contract for a project
When need again since serial number n, avoid out-of-order repeating transmission.

Show, Fig. 5 is illustrated by taking low time delay class game as an example.
Step 411, into game, i.e., running game application in terminal.
Step 422, preferential transmitting have the UDP message of game data mark.It is excellent when TCP/IP layer transmits data to L2
First transmitting has the UDP message of mark (mark is used to identify game data), then, then transmits other TCP or user data
Datagram protocol (User Datagram Protocol, abbreviation UDP).
Step 433, judge game application time delay T1 > T and A2 > Y or A1 > X and A2 > Y it is whether true, A1 when discovery trip
Time delay T1 > the T applied play alternatively, when L2buffer accumulates A1 > X and A2 > Y, goes to step 444 execution.
Step 444, triggering uplink maximum retransmit, and empty uplink caching.That is triggering uplink maximum retransmits, so that terminal is sentenced certainly
Determine RLF (Radio Link Failure), rebuild into Radio Link, rebuild by Radio Link, completes emptying for modem data.It is complete
After rebuilding at Radio Link, the data packet of no confirmation transmitting is re-issued L2 by TCP/IP layer.
Step 455 subsequent is given out a contract for a project again since serial number n.If the data packet of MAC layer is without abandoning, in respective counts
Before being sent according to packet, retransmited after mark (i.e. terminal is identification target object, for the mark of target object addition) need to be removed；If right
The data packet of MAC layer is abandoned, then abandon when, need also accordingly to abandon rlc layer and PDCP layer of packet, and rlc layer with
PDCP packet number keeps continuous, that is, while abandoning corresponding packet, need to record the serial number n of discarding accordingly wrapped, it is subsequent to give out a contract for a project
When need again since serial number n, avoid out-of-order repeating transmission.
Embodiment illustrated in fig. 5, for triggering RLF to completing to rebuild needs tens to several hundred milliseconds, there are certain risks, are only applicable in
After fluctuation in short-term occurs in network, the case where restoring the data in buffer rapidly is needed.
In Fig. 1-embodiment illustrated in fig. 5, under the game Caton scene caused by uplink caching accumulation, by abandoning a part
Game data can be relieved Caton situation.It abandons main according to two ways when game data；If at IP layers by identifying to game
Data are marked, then when abandoning, it can be according to the data for determining game application be identified, to be abandoned；If game number
According to QCI, then counterlogic channel can be mapped to by QCI, the game data on the channel is abandoned.
In the stronger business of real-time, user is very low to the tolerance of time delay, and traditional approach is fluctuated in network environment
In the case of, uplink caches before may needing up to 1s that can just empty every time, be easy to cause multiple Caton, influences user experience.
The present invention can customize the first data-quantity threshold, the second data-quantity threshold and time threshold, pass through what is receded into the background before abandoning
Business datum transmits new data in time, can effectively reduce network from Caton to smooth recovery time, in ambient signal strength
In the case where unstable, delay can be significantly reduced, promotes user experience.Present invention is preferably applicable to the real-times of UDP transmission
