Can only be held if only needing to process the RAB sub-stream datas that RLC module sends according to actual conditions in application
Row S6a01, S6a02 and S6a03；Only carried out if only needing to process the IuUP packets that IuUP modules send S6b01,
S6b02 and S6b03；If not only needing to process the RAB sub-stream datas of RLC module transmission but also needing to process what IuUP modules sent
IuUP packets, then both needed to perform S6a01, S6a02 and S6a03, needs to perform S6b01, S6b02 and S6b03 again.
It is preferred that after S6a01, that is, after receiving the RAB sub-stream datas of RLC module transmission, the embodiment of the present invention
The RAB sub-stream datas that receive can also be cached and whether the RAB sub-stream datas to receiving are detected extremely.For
The business of RAB sub-stream datas is different, and the mode of detection is also differed, is introduced separately below.
First, RAB sub-stream datas are video data：
Specifically, after receiving the RAB sub-stream datas that RLC module sends, each RAB sub-stream data pair that judgement is received
Whether the CFN for answering is continuous, to wireless heterogeneous networks if discontinuous（RRC）Return to fault alarm information；Then to CFN identicals
RAB sub-stream datas carry out duplicate removal treatment, retain in CFN identical RAB sub-stream datas；And RAB that will be remained
Flow data is converted to IuUP packets.
Due in the prior art, for video data, the corresponding RAB sub-stream datas only one of which of same CFN, therefore work as
When there is CFN identical RAB sub-stream datas, it is identical to also imply that these have the RAB sub-stream datas of identical CFN, because
This can only retain one of those, and lose remaining.Herein, can select to retain CFN identicals RAB for receiving
Any one in flow data, can be first received, or receive last, can also be reception
Some for the centre arrived, abandons remaining RAB sub-stream data, and each the RAB sub-stream data that then will be remained is converted to
IuUP packets.
Three RAB sub-stream datas A, B and C are such as received, corresponding CFN is respectively 3,4 and 4.Due to only one of which RAB
Sub-stream data correspondence 3, it is possible to RAB sub-stream datas A is directly converted into an IuUP packet；Due to two RAB subflows
Data correspondence 4, so needing to abandon one of those, can preferably abandon RAB sub-stream data C, and it is forward that reservation is received
RAB sub-stream datas, are then converted to an IuUP packet by RAB sub-stream datas B.
2nd, RAB sub-stream datas are speech data：
For certain CFN for determining, if not having main RAB sub-stream datas in the corresponding RAB sub-stream datas of the CFN, abandoning should
The corresponding RAB sub-stream datas of CFN.
Due in the prior art, for speech data, the corresponding RAB sub-stream datas of same CFN have under normal circumstances
Three, for example, it is the RAB sub-stream datas of N that CFN is searched in the RAB subflows for receiving, under normal circumstances, three can be found
Individual, one of them is main RAB sub-stream datas, and two other is time RAB sub-stream datas, wireless wherein in each RAB sub-stream data
The value of carrying ID identifies the RAB sub-stream datas to be main RAB sub-stream datas or secondary RAB sub-stream datas and is which kind of time RAB
Sub-stream data, for example, it may be the value of radio bearer ID is the 1 main RAB sub-stream datas of mark, the value of radio bearer ID is 2 and 3 points
Biao Shi not two RAB sub-stream datas.Therefore, after all RAB sub-stream datas that CFN is N are determined, then determine that CFN is N's
Whether the value of the radio bearer ID of each RAB sub-stream data simultaneously judges wherein there are the RAB sub-stream datas that radio bearer ID is 1.
If without the RAB sub-stream datas that radio bearer ID is 1, it is all of RAB sub-stream datas of N to abandon CFN.
Assuming that situation one, CFN is that the RAB sub-stream datas of N=1 have 5, the radio bearer ID's of this 5 RAB sub-stream datas
Value is respectively 2,2,3,2,3, and now the value of the radio bearer ID of this 5 RAB sub-stream datas is not 1, and this represents that CFN is 1
There is no main RAB sub-stream datas in this 5 RAB sub-stream datas, because main RAB sub-stream datas cannot recover again, it is therefore desirable to will
CFN is that 1 this 5 RAB sub-stream datas are all lost.
It is preferred that after S6a01, and determine in some CFN correspondence RAB sub-stream datas there is main RAB sub-stream datas
Afterwards, the value identical RAB sub-stream datas of the corresponding radio bearer ID of the corresponding RAB sub-stream datas of the CFN are determined, is retained and is determined
One in the RAB sub-stream datas for going out, abandon remaining RAB sub-stream data.
Specifically, according to CFN for whether the radio bearer ID of the RAB sub-stream datas of N judges wherein there is radio bearer ID's
Value identical RAB sub-stream datas, if it has, any one in then only retaining the value identical RAB sub-stream datas of radio bearer ID
It is individual, first can be retained, it is also possible to retain some middle, last can also be retained, then abandon remaining.
Assuming that situation two, if the CFN for receiving be respectively 1 for the value of the radio bearer ID of 3 RAB sub-stream datas of N=2,
1st, 1, then it represents that have main RAB sub-stream datas in the RAB sub-stream datas for receiving, now due to RAB subflow numbers that radio bearer ID is 1
According to there is three, these three RAB sub-stream datas are identicals.Then, selected in three RAB sub-stream datas that radio bearer ID is 1
A reservation is selected, first can be selected, it is also possible to one in the middle of selection, it is also an option that last, abandons other
Two RAB sub-stream datas.Therefore, the CFN after discarding is 2 RAB sub-stream data only one of which, and its radio bearer ID is 1.
It is preferred that after S6a01, if the number of the corresponding RAB sub-stream datas of the CFN is less than being converted to after abandoning
The number of the RAB sub-stream datas needed for IuUP packets；At least one RAB sub-stream data is generated according to main RAB sub-stream datas,
The number of the secondary RAB sub-stream datas for wherein generating RAB sub-stream datas number sum corresponding with the CFN that participation number compares etc.
The number of the RAB sub-stream datas needed for IuUP packets are converted to.
Further, after S6a01, there is main RAB subflows number in some CFN correspondence RAB sub-stream datas are determined
According to rear, if the value of the corresponding radio bearer ID of the corresponding RAB sub-stream datas of the CFN is differed and the corresponding RAB subflows of the CFN entirely
The number of data is less than the number of the RAB sub-stream datas needed for being converted to IuUP packets；According to main RAB sub-stream datas generate to
Few one RAB sub-stream data, wherein the number of the secondary RAB sub-stream datas for generating is corresponding with the CFN that participation number compares
RAB sub-stream data numbers sum is equal to the number of the RAB sub-stream datas needed for being converted to IuUP packets.
Assuming that situation three, if the CFN for receiving be respectively 1 for the value of the radio bearer ID of 2 RAB sub-stream datas of N=3,
3, due to the value identical RAB sub-stream datas in the absence of radio bearer ID, therefore need not carry out abandoning the RAB subflow numbers of repetition
According to operation.
If specifically, CFN is differed for the value of the corresponding radio bearer ID of RAB sub-stream datas of N is complete or CFN is N's
The value identical RAB sub-stream datas of the corresponding radio bearer ID of RAB sub-stream datas only retain one of them, discard remaining it
Afterwards, CFN is less than the number of the RAB sub-stream datas needed for being converted to IuUP packets for the number of the RAB sub-stream datas of N, for
For prior art, that is, the number of the RAB sub-stream datas that CFN is N is less than three, at this time, it may be necessary to be the master of N according to CFN
RAB sub-stream datas generate at least one RAB sub-stream data, make the number of secondary RAB sub-stream datas of generation and CFN for N
Some RAB sub-stream datas number sums are equal to the number of the RAB sub-stream datas needed for being converted to IuUP packets.
It is preferred that generating at least one RAB sub-stream data according to main RAB sub-stream datas, specifically include：
The secondary RAB sub-stream datas format information generation datagram configured when being set up according to user plane bearer, by datagram
The value of data body portion be revised as default value, and using amended datagram as one RAB sub-stream data.
Assuming that in situation two, because the RAB sub-stream data only one of which radio bearers ID that the CFN after discarding is 2 is 1
RAB sub-stream datas, it is therefore desirable to according to the life of main RAB sub-stream datas that radio bearer ID in the RAB sub-stream datas that CFN is 2 is 1
Into CFN be 2, the RAB sub-stream datas that radio bearer ID is 2 and CFN be 2, the RAB subflow numbers that radio bearer ID is 3
According to.
Generation CFN is 2, and radio bearer ID is that the detailed process of 2 and 3 RAB sub-stream datas is：Held according to user plane first
The radio bearer ID that load is configured when setting up is 2 RAB sub-stream datas format information one datagram of generation, its structure such as Fig. 3 institutes
Show, the UE ID in the datagram, type of message are correspondingly arranged be with CFN be 2, radio bearer ID is 1 RAB sub-stream datas
The value identical value of middle UE ID, type of message, 2 are set to by the value of CFN, and the value of radio bearer ID is set to 2, data length
The radio bearer ID for being set to be configured when user plane bearer is set up is the data length of 2 RAB sub-stream datas, then by data volume
Partial value is revised as the corresponding preset value of RAB sub-stream datas that radio bearer ID is 2, finally using amended datagram as
CFN is 2, and radio bearer ID is 2 RAB sub-stream datas；Generation radio bearer ID be 3 RAB sub-stream datas process with it is above-mentioned
Process is similar to, and will not be repeated here.
Assuming that in situation 3, because only radio bearer ID is 1 and 3 two RAB in RAB sub-stream datas that CFN is 3
Sub-stream data, it is therefore desirable to according to CFN be 3, main RAB sub-stream datas that radio bearer ID is 1 generate CFN be 3, nothing
Line carries the RAB sub-stream datas that ID is 2, and its generating process is 2 with generation CFN in concrete condition 2, and radio bearer ID is 2 RAB
The process of sub-stream data is similar to.
In above process, due to the function of changing up CS user face datas form from RLC module or IuUP modules
In be stripped out, reduce the burden realized difficulty, alleviate RLC module or IuUP modules of RLC module or IuUP modules, from
And improve the efficiency of data processing.
Also, due to the step of dealing of abnormal data is increased during processing upstream data, improve system
To the disposal ability of abnormal data.
It is preferred that after S6b01, after the IuUP packets for receiving the transmission of IuUP modules, the embodiment of the present invention is also
The IuUP packets for receiving can be cached and abnormal verification.The process of abnormal verification is described below.
After the IuUP packets for receiving the transmission of IuUP modules, the data length of the IuUP packets that judgement is received is
The no data length configured when being set up equal to user plane bearer, if equal to, then IuUP packets are converted into RAB subflow numbers
According to；Otherwise abandon the IuUP packets for receiving.
Further, after S6b01, it is by the detailed process that IuUP packets are converted to RAB sub-stream datas：
IuUP packets are first determined whether for video data or speech data, if video data is then according to user plane bearer
Each IuUP packet is converted to RAB sub-stream datas by the information configured when setting up correspondingly, if speech data then root
Each IuUP packet is converted to three RAB sub-stream datas, these three RAB by the information configured when being set up according to user plane bearer
Flow data is respectively the main RAB sub-stream datas that radio bearer ID is 1, and two radio bearer ID are 2 and 3 secondary RAB subflows
Data.
It is preferred that in S6b03, periodically the RAB sub-stream datas after conversion are sent to RLC module.If for example,
Video data, then send two RAB sub-stream datas being converted to by two IuUP packets every 20ms；If voice number
According to three RAB sub-stream datas being then converted to by an IuUp packet every 20ms transmissions.
In above process, due to the function of changing descending CS domains user face data form from RLC module or IuUP moulds
It is stripped out in block, equally reduce RLC module or IuUP modules realizes difficulty, also mitigates RLC module or IuUP modules
Burden, so as to improve the efficiency of data processing.
Also, due to descending CS domains user face data treatment during increased dealing of abnormal data the step of,
Overcome by the problem of stability of a system reduction caused by data exception.
It is additionally, since the IuUP packets to receiving to be cached, and periodically sends by IuUP packets
The RAB sub-stream datas of conversion, so can effectively prevent the data in data transmission procedure caused by time delay difference from trembling
It is dynamic.
Fig. 7 gives the up CS domains user sent to RLC module using a kind of method of CS domains user plane data transfer
Face data, i.e., the RAB sub-stream datas of the datagram structure shown in Fig. 3, the process for being processed comprises the following steps：
S701, receives the RAB sub-stream datas that RLC module sends；
S702, judges that the RAB sub-stream datas for receiving are video data or speech data, if video data, then holds
Row S703, if speech data, then performs S705；
S703, it is determined that the corresponding Connection Frame Number CFN of each RAB sub-stream data for receiving, determines whether the CFN for repeating,
If performing S704, if it is not, performing S711；
S704, retains in CFN identical RAB sub-stream datas, abandons remaining RAB sub-stream data；
After S704, S711 is performed；
Whether S705, for the CFN of same determination, judges there is main RAB subflows number in the corresponding RAB sub-stream datas of the CFN
According to；Its specific practice is：After RAB sub-stream datas are received, it is determined that each the corresponding Connection Frame Number of RAB sub-stream datas for receiving
Whether CFN, judges there are main RAB sub-stream datas in the corresponding RAB sub-stream datas of each CFN one by one；For a certain CFN, judge
Whether there are main RAB sub-stream datas in the corresponding RAB sub-stream datas of the CFN；If so, S707 is then performed, if it is not, then performing S706；
S706, abandons the corresponding RAB sub-stream datas of the CFN；
Whether S707, judges there is the RAB sub-stream datas of repetition, its specific practice in the corresponding RAB sub-stream datas of the CFN
For：Whether have identical, if so, determining radio bearer if judging the value of radio bearer ID in the corresponding RAB sub-stream datas of the CFN
The value identical RAB sub-stream datas of ID simultaneously perform S708, if it is not, then performing S709；
S708, abandons remaining RAB sub-stream data by one in the RAB sub-stream datas that reservation is determined；
S709, judge S707 or S708 treatment after the corresponding RAB sub-stream datas of the CFN number whether less than conversion
The number of the RAB sub-stream datas for needed for IuUP packets, if so, S710 is then performed, if it is not, then performing S711；
S710, the information configured when being set up according to the corresponding main RAB sub-stream datas of the CFN and user plane bearer generate to
Few one RAB sub-stream data, wherein the number of the secondary RAB sub-stream datas for generating is corresponding with the CFN that participation number compares
RAB sub-stream data numbers sum is equal to the number of the RAB sub-stream datas needed for being converted to IuUP packets.
S711, by S703 or S704 treatment after the corresponding RAB sub-stream datas of each CFN be converted to an IuUP packet
And IuUP modules are sent to, or the corresponding RAB sub-stream datas of the CFN after S709 or S710 treatment are converted to one
IuUP packets are simultaneously sent to IuUP modules.
The process processed RAB sub-stream datas be given in Fig. 7, only a kind of preferably processing procedure, at this
During first determine whether whether there are main RAB sub-stream datas in the corresponding RAB sub-stream datas of each CFN, and discard and do not include
The corresponding RAB sub-stream datas of CFN of main RAB sub-stream datas, it is then determined that going out the corresponding RAB of CFN comprising main RAB sub-stream datas
The RAB sub-stream datas repeated in sub-stream data, one in the RAB sub-stream datas that reservation is determined, and abandon remaining RAB
Flow data.Therefore, using the method shown in Fig. 7, it is not necessary to judge the corresponding RAB subflows of CFN not comprising main RAB sub-stream datas
Whether there are the RAB sub-stream datas of repetition in data and determine the repetition RAB sub-stream datas for wherein including, therefore use the mistake
Journey can further improve the efficiency of data processing.
Certainly, the process for being processed RAB sub-stream datas, can also use and determine each CFN pairs one by one first
The RAB sub-stream datas repeated in the RAB sub-stream datas answered, in only retaining the corresponding RAB sub-stream datas of the same CFN for determining
One, and remaining RAB sub-stream data is abandoned, then judge whether there is master in the corresponding RAB sub-stream datas of each CFN again
RAB sub-stream datas, and the processing procedure of the corresponding RAB sub-stream datas of CFN not comprising main RAB sub-stream datas is discarded, at this
Reason process is as shown in Figure 8.
Below, the flow of the treatment RAB sub-stream datas that Fig. 8 is given specifically is introduced, is comprised the following steps：
S701, receives the RAB sub-stream datas that RLC module sends；
