According to the RLC entities for consigning to opposite end.As shown in figure 1, the logic communication framework of base station includes 4 Rotating fields, wherein, use RLC
The rlc layer of agreement is located at PDCP (packet data convergence protocol, PDCP) layer and matchmaker
Between body Access Control (medium access control, MAC) layer, interacting for message is carried out with PDCP layers and MAC layer.Eventually
The logic communication framework at end is 5 layers, except it is high-rise (upper layer, including IP layers and transport layer (TCP layer/UDP layers), should
With layer) outside, other 4 layers are identical with base station.
Each logic channel in Fig. 1 between base station and terminal has a RLC entity (RLC Entity).Rlc layer
Function is realized that each RLC entities are by wireless heterogeneous networks (radio resource control, RRC) layer (figure by RLC entities
1 is not drawn into) configure, correspond to some business of some terminal.The data that RLC entities receive from PDCP layers, or it is sent to PDCP layers
Data be referred to as RLC Service Data Units (service data unit, SDU).RLC entities are from media access control
The data that (Media Access Control, MAC) layer receives, or be sent to the data of MAC layer and be referred to as rlc protocol data sheet
First (Protocol Data Unit, PDU).
According to existing agreement 3GPP TS 36.322, rlc layer recombinates out for the RLC PDU received from MAC layer
RLC SDU, which need sequentially to submit (In-sequence delivery), arrives PDCP layers, and the basic thought sequentially submitted is, ought
Before the serial number x RLC PDU that receive be stored in rlc layer caching, until all RLC PDUs of the sequence number less than x all into
Work(is received and is reassembled as after RLC SDU are delivered to PDCP layers, and next RLC PDU can just be recombinated.By taking Fig. 2 as an example, such as
Fruit RLC layers received sequence number 23 before all RLC PDU and sequence number 25-27 RLC PDU, because PDU 24 does not connect also
(possible packet loss) is received, it is necessary to wait until that PDU 24 is properly received always, RLC SDU restructuring can be just carried out and submit.
It can be seen that message sequentially submits method because to wait the message of missing to be received, larger time delay can be caused, easily
Reduce transmission performance.In order to avoid this problem, the non-sequential for generating message submits method：As long as the RLC PDU received
Part RLC SDU are recombinated out enough, then without waiting for the message of missing, will recombinate out and passed for the insensitive RLC SDU of sequential
It is sent to PDCP layers.By taking Fig. 3 as an example, if rlc layer received sequence number 23 before all RLC PDU and sequence number 25-27 RLC
PDU, do not receive PDU 24 also, do not wait for receiving PDU 24, and utilize the RLC PDU received, recombinate out RLC SDU
10th, 11,13 and 14 (the restructuring mapping relations according to PDU and SDU recombinate), and submitted to PDCP layers in the RLC SDU recombinated out
To out of order insensitive message.
However, it is necessary to the package informatin according to message determines whether message is to out of order insensitive message, for encryption
For message, the package informatin of message can not be directly obtained, therefore, the non-sequential of existing message submits method, is not suitable for adding

Literary type, that is to say, that the set includes submitting insensitive type of message for non-sequential.For example, non-sequential submits class
Type set includes QUIC ACK type of messages.Type set can be submitted according to actual demand, flexible configuration non-sequential.
After the up RLC SDU type of message of restructuring is got as QUIC ACK, type set is submitted from non-sequential
Middle inquiry whether there is QUIC ACK type of messages.
S406：The up RLC SDU of restructuring are delivered to PDCP layers, and the RLC SDU submitted non-sequential are carried out subsequently
Processing.
The process of subsequent treatment can be found in prior art, repeat no more here.
Because high-rise (application layer) may have different out of order treatment mechanisms, for example be received for the out of order of TCP message, TCP
End may reply repeat ACK, and triggering originator retransmits, and transmission performance declines on the contrary.So and not all RLC SDU can
Non-sequential is delivered to high level, it is seen then that identifies certain types of message, is an important means of this programme, QUIC is reported here
Insensitive message is submitted non-sequential in text mainly includes QUIC ACK messages etc..
S407：After wait receives whole RLC PDU in up RLC PDU sequences, up RLC PDU sequences are reused
Up RLC SDU are recombinated out, and the up RLC SDU of restructuring are sequentially delivered to PDCP layers, and the RLC SDU to sequentially submitting
Carry out subsequent treatment.
Method shown in Fig. 4, for encrypted message, the encrypted message that judges to receive according to the feature of the message of transmission
Type so that encrypted message can also realize that non-sequential is submitted.It is by taking QUIC ACK messages as an example, RLC is non-in the present embodiment
It is used for QUIC business to the scheme Innovation sequentially submitted.The program is in the case where the up RLC PDU receptions of QUIC business are out of order
Come into force.There is gain for the QUIC business under out of order rate high field scape, substantially reduce uplink feedback bag propagation delay time, reduce factor
According to upper layer node packet loss caused by burst, so as to lift the descending throughput of network QUIC business and downlink user experience.
Method shown in Fig. 4 can be compatible with the method that existing non-sequential is submitted, as the supplement of existing scheme, extension
Non-sequential submits the suitable application area of scheme.
Fig. 5 is that the non-sequential of another message disclosed in the embodiment of the present application submits method, is comprised the following steps：
S501：Up RLC PDU sequences are obtained, at least one RLC PDU are lacked in up RLC PDU sequences.
Optionally, after up RLC PDU sequences are received, up RLC in up RLC PDU sequences can also be judged
PDU integrality, and complete up RLC PDU are cached, renewal RLC state variables etc..
S502：According to the restructuring mapping relations between default RLC PDU and RLC SDU, the up RLC received is used
PDU sequences recombinate out up RLC SDU.
S503：Judge the up RLC SDU load type recombinated out, if QUIC, S504 is performed, if TCP
Or UDP, perform S505.
S504：According to the feature of the downlink message sent, it is determined that the up RLC SDU recombinated out type of message.
S505：According to the up RLC SDU recombinated out information, it is determined that the up RLC SDU recombinated out type of message.
Specific determination method may refer to prior art, repeat no more here.
S506：Whether the type of message for the up RLC SDU that query reformulation goes out is that non-sequential submits type, if it is, holding
Row S507, if not, performing S508.
S507：The up RLC SDU of restructuring are delivered to PDCP layers, and the RLC SDU submitted non-sequential are carried out subsequently
