UDP is a kind of towards connectionless transport layer protocol in OSI Reference Model, and it is mainly used in not requiring order of packets
In the transmission arrived, the inspection of packet transmission sequence is completed by application layer with sequence.It is different from towards connecting-type agreement, thus
There is the advantages such as resource consumption is little, processing speed is fast, so generally audio frequency, video and general data use UDP relatively when transmitting
Many.Even if because they lose one or two packet once in a while, also will not have much impact to receiving result.Owing to UDP may
There is the phenomenon of packet loss, it is only used as the ground floor for the treatment of method.
TCP/IP is broadly divided into two parts: tcp data information and IP packet.Tcp data information is represented by: TCP header
Portion+real data (TCP header includes: source and target host side slogan, serial number, confirmation number, check word etc.).IP packet can table
It is shown as: IP head+tcp data information (IP head includes: source and target host IP address, type, life cycle etc.).Transmission Control Protocol is used
It is for setting up retransmission timer the need of the foundation retransmitted in controlling data segment.One is started while sending a data segment
Retransmission timer, if receive confirmation to be shut off this intervalometer, if do not received before timer expiry before timer expiry
Confirm, then retransmit this data segment.Exactly because also this characteristic, it is used alone Transmission Control Protocol in the wireless network and the most likely blocks up
Plug is eated dishes without rice or wine, and causes the data can not normal propagation.

The schematic flow sheet of reason method.As in figure 2 it is shown, the present invention provides client layer data in the fall detection system of a kind of actual deployment
Processing method, including: detection IP traffic；Judge that network is the most stable or server end packet receiving is existing with or without obvious out of order packet loss
As, if network stabilization and server end packet receiving are without obvious out of order packet loss phenomenon, then use udp protocol transmission of IP data stream, if net
Network is unstable or server end packet receiving has obvious out of order packet loss phenomenon, then use Transmission Control Protocol transmission of IP data stream；When using TCP
During protocol transmission IP traffic, it is judged that whether IP traffic is the ack msg bag of Transmission Control Protocol, the most then by IP traffic labelling
Process for high priority grouped convergence (PDCP) and be sent to high priority after wireless chain control layer (RLC) process
Passage is transmitted, if it is not, IP traffic is then labeled as low priority and is sent to low excellent after PDCP processes and RLC processes
First level passage is transmitted.
Further, described RLC process may include that high-rise PDU packets different for length is carried out segmentation is reassembled as RLC
Load cell (LU)；When the content of a RLC SDU can not fill up a complete RLC PDU, by next RLC SDU's
First paragraph is also placed in this LU, is concatenated together with the final stage of previous RLC SDU；When the content of RLC SDU can not be filled out
When expiring a complete RLC PDU and cannot be carried out cascade, remaining space filling bit is filled up；At RLC PDU quilt
When being reassembled as RLC SDU, by checking that RLC SDU state is checked by the serial number of RLC PDU；The mistake of detection rlc protocol
Miss and recover.
Further, described PDCP process farther includes: obtain the IP packet from upper strata；To IP packet
Carry out head compression and encryption；IP packet after compression and encryption is sent to rlc sublayer；There is provided and sequentially submit to and repeat point
Group detection service.
Further, described offer is sequentially submitted to and is farther included with repeated packets detection service: provide letter for upper strata RRC
Order transmission service, and realize encryption and the consistency protection of RRC signaling, and realize in the reverse direction RRC signaling deciphering and
Consistency check.
Such as, contribute to realizing in a wireless communication system the data relevant to switching are transmitted the system being managed,
Can include node B (such as, base station, access point (AP), the node B (eNB) etc. of evolution), the latter with can be with one or many
Individual user equipment unit (UE, the most also known as access terminal (AT), mobile terminal etc.) 130 communicates.Lift one
Individual example, node B above can communicate with UE at one or more downlinks (DL, also referred to as forward link (FL)), UE
Above can communicate with node B in one or more up-links (UL, also referred to as reverse link (RL)).Lift an example again
Son, node B can be with cordless communication network (such as, UMTS (UMTS) land radio access web (E-of evolution
UTRAN) or one part (such as, community, sector etc.)) be associated.Additionally, node B can be with other nets one or more
Network entity (such as, system controller (not shown) etc.) collaborative work, in order to the communication between coordinator node B and UE.
Can the transmission of the respective packets in execution system in the scene of one or more communication layers of system protocol stack.Example
As, packet data convergence protocol (PDCP) layer, wireless spread-spectrum technology (RLC) layer, medium access control (MAC) layer and layer 1 (L1)
May be used for respective complexity to realize the various aspects of radio communication.So, such as, PDCP protocol layer may be used for
Performing data compression and sequence and/or other HLF high layer function, rlc layer may be used for managing transmission and/or the re-transmission of various data,
MAC layer may be used for that corresponding relevant device is linked into the communication resource relevant to network and is managed, and L1 may be used for relatively
The physical air interface relevant to giving the network equipment is managed on low layer.It is to be understood that be with particular example above
Mode be given, random layer can carry out the most suitable function.However, it should be understood that system can be with the suitableeest
When order use the one group of communication layers being arbitrarily suitable for.
Layer can be associated with various PDU forms, in order to the communication contributing to combining information manages and/or processes
Information on one or more layers.Therefore, corresponding PDCPPDU can be relevant to PDCP protocol layer, PDCPPDU may be embodied in
In the RLCPDU that rlc layer is relevant.It should be appreciated that can in any suitable way PDCPPDU be mapped in RLCPDU.
Therefore, map one to one, many-one maps, one-to-many maps and/or arbitrarily other suitably mapping may be used to PDCPPDU
It is encapsulated in corresponding RLCPDU.It should be appreciated that additionally or alternatively, MAC layer, L1 and/or and radio communication
Other layer any that system is relevant can use PDU form, in order to processes information in given equivalent layer.
The combination of coupling layer, such as, PDCP protocol layer and rlc layer can be come by corresponding data radio bearer (DRB).Can
With the corresponding DRB that offer is corresponding to the corresponding pipeline between PDCP protocol layer and rlc layer.Such as, corresponding DRB may be used for right
The data corresponding with one or more PDCPPDU arrange, in order to be transmitted the most in a wireless communication system.This
Outward, DRB may be used for preserving PDCP status message, and can generate with as further detailed below and/or use
PDCP status message.For example, it is possible to distribute priority value to DRB, so that based in part on the respective priority of DRB,
Launch the information through arrangement in DRB.Therefore, DRB can have limit priority, and DRB can have secondary limit priority,
DRB can have lowest priority.It is to be understood that can set up preferential between DRB in any suitable manner
Level, and given respective priority can apply to any an appropriate number of DRB.
System can be adaptive, in order to optimizes the communication performance of given UE.It is therefoie, for example, if it occur that following feelings
Condition: producing the wireless conditions of decline between node B and UE, the overlay area of UE removal node B, the service that UE needs is node B
Have no ability to or capacity provides, or other reason, then can carry out transferring to the service for UE from source node B
The switching of target node b.
According to handoff procedure above, the UE in system may be used for using the corresponding PDCP status message on corresponding DRB as
The after handoff completion message first packet is followed to launch.Give one example, can be in the upper transmitting of Signaling Radio Bearer (SRB)
In the DLPDCPPDU that PDCP status message, its DLPDCPPDU that can serve to indicate that loss and/or instruction are sequentially received
The sequence number (SN) of later DLPDCPPDU.So, lift a concrete example, if UE is from Node-B receiver to given DRB
The PDCPPDU with serial number 1,2,4,6 and 10, then the PDCP status message of this DRB may indicate that and lost serial number
3, the PDCPPDU of 5,7,8 and the 9 and PDCPPDU of instruction serial number 2 is last of the PDU that is sequentially received.Therefore,
Node B can discharge the memorizer for storing PDU1,2,4,6 and 10, and carries out weight only for PDU3,5,7,8 and 9 lost
Pass.In similar concrete example, if corresponding PDCPPDU is encapsulated in corresponding RLCPDU, then UE can send out to node B
The RLC corresponding for RLCPDU penetrated and had correctly received by UE confirms (ACK).If it is therefoie, for example, RLCPDU is configured to
Comprise and there are five PDCPPDU that SN is 1-5, then UE may be used for being properly received the rear to node B submission pin of RLCPDU
ACK to RLCPDU, thus node B can discharge suitable memorizer and stop the re-transmission of PDCPPDU1-5.
In conventional radio communication realizes, the scheduler algorithms that respective nodes B and/or UE are used is not known in switching
The status message (such as, PDCP status message, RLCACK) generated afterwards and/or at other appropriate time.It should be appreciated that
Corresponding entity in wireless communication system is for launching data in respective logical channels, in order to meet drawing of respective logical channels
Divide order of priority bit rate (PBR) and/or one or more other similar condition.
It is understood, therefore, that when using multiple channels to be transmitted, in some cases, routine dispactching algorithm
The transmitting of the status message corresponding with second channel or subsequent channel was stoped, it may be assumed that meet first before meeting following condition
The PBR of channel, all data are substantially all removal the first channel and/or after meeting other condition.This causes being delayed state
The transmission of message, thus prevent the substantive benefit from these status messages of the entity in system.Such as, if in system
Transmitting entity is not received by (such as, passing through to asking one or more reports that the data lost are carried out re-transmission relevant
PDCP status message, RLCACK etc.), then in some cases, transmitting entity can not select for quite a few data
Retransmitting, this can cause the loss of these data in the case of losing data and expecting to retransmit.Or, if lacking shape
State is reported, transmitting entity assume that each several part of data is not the most received, and retransmits these parts.But, should
When being understood by, if be properly received in original transmitted in the data retransmitted is at least some of, then will
The data causing unwanted repetition on up-link and/or downlink are transmitted.However, it should be understood that with this side
Formula carries out repeating to transmit the low service efficiency that may further result in transmitting entity for memorizer, this is because transmitting entity can not
Discharge the memorizer relevant with the data relevant to repeating transmission.

This, as above generally described in, the entity for receiving these status messages can avoid repeating transmission and keeping away of data
Exempt to waste the aerial download bandwidth on up-link and/or downlink.Such as, division order of priority module may insure that and cutting
The most afterwards the report of PDCP state is provided sufficiently high priority, so that in targeted arbitrarily the patrolling of PDCP state report request
Collect and do not carry out data transmission on channel or retransmit, until substantially having launched whole PDCP state reports.Lift one again
Example, by the following means, dividing order of priority module can operate for the DRB with limited PBR: meeting arbitrarily
The PDCP status message transmitting on corresponding DRB is promoted before the PBR of relevant DRB.Or, any by corresponding DRB
Data are transmitted the PDCP status message promoting to transmit on corresponding DRB before, and dividing order of priority module can be for basis
Strict priority carrys out the DRB (such as, relevant to unlimited PBR) of work and operates.Separately give one example, divide order of priority
Module contributes to realizing the status message on arbitrarily other suitable logic channel (such as, Signaling Radio Bearer (SRB) etc.)
Divide order of priority.
May be used in addition to PDCP status message and/or replacement PDCP state additionally, divide order of priority module
The RLC status message (such as, including one or more ACK and/or the RLCSTATUS message of negative ACK (NACK)) of message is drawn
Divide order of priority.Therefore, during the communication session between node B and UE and/or arbitrarily other appropriate time, data can be made
Analyzer or divide order of priority module and recognize and there is the type of corresponding RLC status message and/or each of which (such as, no
Whether these message of opinion comprise nack message), in order to compare the new data transmission on other logic channel and/or data retransmit and
Speech, is allocated to the higher priority of RLC status message.It is understood, therefore, that reception RLC status message can be used in
Entity during communication session, understand Negative Acknowledgement as far as possible, so that it is guaranteed that the smooth outflow of data on given channel.
However, it should be understood that by this way RLC status message being divided order of priority, can substantially avoid being not required to
Want the weight of data (such as, original transmission but receiving entity does not carry out, due to Status Disable intervalometer, the data confirmed)
Pass, insufficient UL/DL authorizes and/or other factors.
The data-analyzing machine of the data-analyzing machine of node B and division order of priority module and/or UE and division order of priority
Module may be used for the status message relevant to the limited subgroup of application is divided order of priority.For example, it is possible to application in real time
(such as, network voice protocol (VoIP) application etc.) and/or sensitive At All Other Times or other application do not divide order of priority.
Such as, after setting up the communication session for given application, node B and/or UE may determine that whether this application is that the time is quick
Sense, and after obtaining affirmative judgement result, some or all orders of priority as described above for this application can be made
Divide and lost efficacy.
