Description
Technical field
The present invention relates to moving communicating field, professional data transmission method and the device of TCP among particularly a kind of mobile network.
Background technology
In mobile network's service application; The transmission of the packet of most of service application all is based on TCP (Transmission Control Protocol; Transmission control protocol) host-host protocol can abbreviate the service application based on the transmission of TCP host-host protocol as the TCP business, for example; The download of the transmitting-receiving of mail, the transmitting-receiving of instant message, WEB (webpage) data on flows and upload, FTP (File Transfer Protocol, FTP) downloads, the download of video etc.The transmission of above-mentioned business datum based on the TCP host-host protocol is based on QoS of survice (Quality of Service; Service quality) guarantee is set up; Through QCI (Quality of Service Class Identifier; Quality of service class identifies) and the definite unique carrying corresponding with the packet of the service application that will transmit of ARP (Address Resolution Protocol, address resolution protocol).Because the TCP host-host protocol is based on affirmation mechanism; The corresponding respond packet (ACK/NACK bag) of each packet (comprising that ACK confirms that bag and NACK deny bag); And because the packet of same service application has identical qos requirement with respond packet; Therefore in same carrying, transmit, and have identical dispatching priority.
TD-LTE (Time Division Long Term Evolution; The timesharing Long Term Evolution) laboratory test results shows; A plurality of TCP business are carried on when (promptly transmitting data through same carrying) in the same carrying; Exist the professional respond packet of TCP of low priority in time not to be scheduled, the problem that causes the TCP traffic transmission speed of low priority to be fallen suddenly.
In the prior art; A plurality of TCP business are carried on different transmission person Bearer respectively and (promptly carry; Comprise default bearing or dedicated bearer) in the time, the professional packet of each TCP and the professional respond packet of this TCP remain through same carrying transmission, and because the respond packet of same business has identical dispatching priority with packet; There is not priority scheduling, therefore causes the reduction of TCP traffic transmission speed.
And the TD-LTE laboratory tests show; When the business of the business of the upload file of the ftp business of unique user and file in download is carried out simultaneously; Because upstream data and downlink data all transmit through default bearing; Therefore the business of FTP file in download can receive the influence of the business of upload file, and speed is fallen suddenly, reduces user experience significantly.
In the prior art, the business of the business of FTP upload file and FTP file in download is two typical business based on the TCP host-host protocol.The transfer of data principle of a plurality of TCP of client while Request Processing professional (is example with the business of FTP upload file and the business of FTP file in download) under the TD-LTE system is following.
The business (downlink business) of transmitting file under the business (uplink service) of FTP upload file, the FTP is referred to as ftp business.Ftp business is based on " client/server " model, has two kinds of transmission meanss:
A kind of mode is Standard (standard) pattern (being the PORT mode, active mode), and the client transmission PORT that initiates ftp business orders ftp server;
A kind of mode is Passive (passive) pattern (being the PASV mode, passive mode), and the client transmission PASV that initiates ftp business orders FTP Server (server).Most of ftp client acquiescence is used the PASV mode, and promptly preset first-selected transmission means is the PASV mode, and IE (Internet Explorer, web browser) acquiescence is used the PORT mode, and promptly the preset first-selected transmission means of IE is the PORT mode.
The sketch map of the transfer of data principle that ftp business is basic is as shown in Figure 1, and when carrying out transfer of data, set up two TCP between the client and server of FTP and connect: control connection is connected with data.
The basic data transmission step of ftp business is following:
Step 101: client is initiated control connection and is set up request (being that user end to server sends the FTP request).Client-requested is set up control with the port 21 of server and is linked.
Step 102: client is set up control with server through the port 21 of server and is linked.The port 21 here is called the session port.
Step 103: client uses Quality Initiative to receive and send FTP order (comprising PORT order and PASV order) to server, and server use Quality Initiative receives and sends corresponding FTP and replys to client.
Step 104: client is set up data with server and is connected.Client is sent a data transfer request and is given server, and server is set up data according to the transmission means of ftp business and connected, and comprising:
If the transmission mode of ftp business is the Standard pattern, server is set up data through port 20 and client and is connected;
If the transmission mode of ftp business is the Passive pattern, bigger port of server selection is set up data with client and is connected.
Step 105: transfer of data.After data connected foundation, a square tube of transmission data was crossed this data connection and is sent data to the other side.At this moment, the packet of the packet of uplink service and respond packet and downlink business and respond packet are all transmitted through default bearing.
The transfer of data principle of the ftp business in the TD-LTE system is following.
The business of the business of FTP upload file and FTP file in download all belongs to ftp business, has identical qos requirement, and therefore, uplink service and downlink business in the prior art in the ftp business all are carried in the default bearing.Fig. 2 has shown the professional sketch map through same carrying transmission data of up-downgoing, is up-downgoing business in the ftp business is transmitted data simultaneously through same carrying sketch map in the present embodiment.
The step of the transfer of data of two ftp business in the above-mentioned sketch map is as shown in Figure 3.
Step 301: client is connected to EPC (Evolved Packet Core, mobile core network evolution) network after start, after initiating the downlink business request, sets up default bearing, and the QCI of default bearing is generally 8 or 9.
Step 302: client is carried out the transfer of data of downlink business through default bearing, comprises packet and respond packet.At this moment, server sends the packet of downlink business to client.
Message transmission rate can reach peak value in this process.Because a file comprises a plurality of packets, therefore, download the downlink business of a file and need download a plurality of packets.Client is after every reception finishes a packet of above-mentioned downlink business, to the professional respond packet of corresponding downstream of server feedback.
Step 303: same client initiates to carry out through same default bearing the uplink service of transfer of data when carrying out above-mentioned downlink business.
Step 304: after client was initiated uplink service, client was sent the packet of uplink service to server through above-mentioned same default bearing.
Server is after reception finishes a packet of the uplink service that client sends, to the respond packet of a corresponding uplink service of client feedback.
When as can be seen from Figure 2 single client is carried out the up-downgoing business simultaneously, in same default bearing, transmit.Because the TD-LTE system is based on and carries that Bearer dispatches; At this moment; The respond packet of downlink business and the packet of uplink service have identical dispatching priority in same carrying, and the up-downgoing business of TD-LTE system interface-free resources has asymmetry; Therefore, the scheduling meeting of the respond packet of downlink business receives the influence of uplink service.
This is because compared to respond packet, the transmission time of packet is longer.Therefore; In the same carrying formation; If the packet of a uplink service is positioned at before the respond packet of a downlink business; The packet with this uplink service be transmitted finish after, just can transmit the respond packet of this downlink business, can cause the respond packet of this downlink business to wait for the overlong time that is transmitted like this.And server is behind the packet that sends a downlink business; If do not receive client feedback to respond packet that should packet; Just can not continue to send the packet of next downlink business; Will cause the speed of downlink business to be fallen suddenly like this, and that uplink service receive the influence of downlink business is less.
It is 38 ~ 45M per second that test shows, single client are carried out downlink business speed, if carry out the up-downgoing business simultaneously, then downlink business speed can be reduced to the 2M per second suddenly.If reduce the thread of uplink service, under the condition of certain interface-free resources, the respond packet of uplink service is transmitted corresponding increase, and then the speed of downlink business can corresponding improve.
Unique user carries out the up-downgoing business simultaneously; And it is as shown in Figure 4 that uplink service and downlink business are carried in the different bearer data transmission procedure of (business that is the FTP upload file is carried transmission through, and the business of FTP file in download is carried transmission through another) respectively.The professional while of the up-downgoing of single client, because downlink business has identical qos requirement with uplink service, therefore, speed to each other can interact when in different carryings, transmitting.
Unique user carries out the up-downgoing business simultaneously, and uplink service is as shown in Figure 5 through the process of different carrying transmission respectively with downlink business, and concrete steps are following.
Step 501: client is connected to the EPC network, and the transfer of data of uplink service is carried out in request, sets up default bearing, and its QCI is generally 8 or 9.
Step 502: client is carried out uplink service, and client is sent the packet of uplink service through default bearing to server, and passes through the respond packet of the uplink service of default bearing reception server feedback.
Step 503: if when carrying out uplink service, client-requested is carried out downlink business, then sets up dedicated bearer, promptly initiates QCI and be the flow process of setting up of 6 dedicated bearer.
Step 504: the packet of the downlink business that client is sent through the dedicated bearer reception server of setting up in the step 502, and to the respond packet of server feedback downlink business.
Because the dispatching priority of dedicated bearer is higher than default bearing; Therefore; In the said process; Be carried on the packet of the downlink business in the dedicated bearer and the dispatching priority of respond packet and be higher than packet and the respond packet that is carried on the uplink service in the default bearing, thereby make the speed of uplink service fall suddenly, it is then less that downlink business receives the influence of uplink service.
Can know through above-mentioned analysis; In the prior art; When a plurality of TCP business are carried in the different carryings; The professional speed of TCP through the high dedicated bearer of dispatching priority transmission data can be higher than through the TCP of the low default bearing transmission data of dispatching priority professional, and the TCP business through the high carrying transmission data of dispatching priority to receive the professional influence of the TCP of the carrying transmission data through low priority less.And the professional influence of TCP that the TCP business through the low carrying of dispatching priority transmission data can receive through the high carrying transmission data of dispatching priority causes speed to fall suddenly.
Generally speaking; No matter be to carry the professional data of a plurality of TCP of transmission or transmit the professional data of a plurality of TCP respectively in the prior art, all can there be part TCP business to receive the professional influence of other TCP and the speed that causes transmitting data is fallen suddenly through a plurality of carryings through one.
Summary of the invention

Embodiment
When the present invention can solve a plurality of TCP business and carries out simultaneously, this TCP service rate decline problem that in time is not scheduled and causes owing to the professional respond packet of TCP.
Client is in the process of professional packet of the current TCP of transmission and corresponding respond packet in the embodiment of the invention, and it is as shown in Figure 6 that client-requested is carried out the process of the professional transfer of data of at least one other TCP.
Step 601: client-requested is carried out the professional transfer of data of current TCP.
Step 602: between client and server, set up the first kind and carry, and carry professional packet of the current TCP of transmission and corresponding respond packet through the first kind.
Carry if set up a first kind between client and the server, then carry professional packet of the current TCP of transmission and corresponding respond packet through this first kind;
Carry if between client and server, set up a plurality of first kind, then preferable, carry professional packet of the current TCP of transmission and corresponding respond packet through one of them first kind.At this moment, current TCP traffic transmission speed can reach peak value.
Step 603: in the process of transmitting professional packet of the first kind and corresponding respond packet, client-requested is carried out the professional transfer of data of at least one other TCP, and sets up second type of carrying.
Step 604: client is carried the professional packet of professional and above-mentioned other TCP of the current TCP of transmission through the first kind, and carries the professional respond packet of professional and above-mentioned other TCP of the current TCP of transmission through second type.
Carry if set up a first kind in the step 602, then client is carried the professional packet of professional and above-mentioned other TCP of the current TCP of transmission through this first kind in step 604;
If having set up a plurality of first kind in the step 602 carries; Then client can be carried the current professional packet of at least one TCP of transmission through each first kind in step 604; Be that each first kind is carried the professional packet of the one or more TCP of transmission; For example, a first kind is carried professional packet of up TCP of transmission, and another first kind is carried professional packet of descending TCP of transmission.
If set up second type of carrying in the step 604, then client is carried professional and above-mentioned other the packet of TCP business of the current TCP of transmission through this first kind in step 604;
If set up a plurality of second type of carrying in the step 603; Then client then can be carried the current professional respond packet of at least one TCP of transmission through each second type in step 604; Be each second type and carry the professional respond packet of the one or more TCP of transmission; For example, one second type carries professional packet of up TCP of transmission, and professional packet of descending TCP of another second type carrying transmission.
The first kind in the said process is carried the default bearing that can adopt dialogue-based port, and second type of carrying can be the dedicated bearer based on preset port.
In the R7 of 3GPP standard, introduced PCC (Policy and Charging Control; Policy control and charging) framework; PCRF (Policy and Charging Rules Function, strategy and charging rule functions) and two functional entitys of PCEF (Policy and Charging Enforcement Function) have been increased.Operator's definable is static with dynamically PCC is regular, and whether network side initiates the foundation of special feature (Dedicated Bearer, dedicated bearer) according to PCC rule and type of service decision, thereby ensures through the professional QoS of special feature completion.
The present invention following embodiment is to be example with the ftp business in the TCP business, and wherein client is in the data transmission procedure that carries out a FTP downlink business, and the transfer of data of a FTP uplink service is carried out in request, and is as shown in Figure 7.
Step 1: in the TD-LTE system, PCRF disposes dynamic PCC rule and it is handed down to P-GW (Gateway/Network side).
P-GW is used to discern the FTP downlink business, and is used to notify client to set up dedicated bearer.
Step 2: client is connected to the EPC network, before carrying out the TCP downlink business, between client and server, sets up default bearing, and the above-mentioned process of setting up is transmitted to the dynamic PPC rule of client according to P-GW, and the QCI of default bearing is generally 8 or 9.
Step 3: client is carried out the FTP uplink service, and speed is normal, can reach peak value.
Client is wrapped with confirming through the packet of default bearing transmission FTP uplink service.
Step 4: same client is initiated the FTP downlink business in the transfer of data of carrying out the FTP uplink service.
Promptly in the process of packet that transmits the FTP uplink service and corresponding respond packet, client-requested is carried out the transfer of data of FTP downlink business.
After step 5: P-GW identifies the FTP downlink business of client-requested; Notice PCRF disposes dynamic PCC rule; And the notice client to initiate QCI according to dynamic PPC rule be that 6 Non-GBR (Guaranteed Bit Rate guarantees bit rate) dedicated bearer is set up process.
Step 6: after dedicated bearer was set up, through the professional respond packet of dedicated bearer transmission FTP up-downgoing, through the professional packet of default bearing transmission FTP up-downgoing, speed was near peak value.
In said process, can in step 2, set up two default bearings, a QCI is that 8 one QCI are 9.Like this in step 3 client through QCI be 8 default bearing transmission FTP uplink service packet with confirm bag; And in step 5; Client is the packet of 8 default bearing transmission FTP uplink service through QCI; Through QCI is the packet of 9 default bearing transmission FTP downlink data, through the professional respond packet of dedicated bearer transmission FTP up-downgoing.
When setting up special feature, need to consider IP (Internet Protocol, Internet protocol) five-tuple information.Server end uses fixed port 20 under the Standard pattern, can be that 20 carrying is set up corresponding dedicated bearer TFT (Traffic Flow Template, traffic flow template) as the five-tuple important parameter with fixed port.Under the Passive pattern, the port of server and the port of client are not fixed, but can the port range that server uses be set at server side.In the time can not port range being set, need P-GW to have DPI (Deep Packet Inspection, deep packet inspection technical) function, resolve the FTP data traffic flows, identification FTP data download bag and feedback packet.
Peak value when test in the laboratory, can configuring static PCC rule, let FTP downlink business feedback packet and FTP uplink service feedback packet be carried on the dedicated bearer, FTP downlink service data bag and FTP uplink business data bag are carried on the default bearing.Base station side is when dispatching based on carrying; Because TCPACK/NACK feedback packet (being respond packet) is less, and depends on the FTP packet rate, Buffer (buffer storage) is difficult to saturated; The moment scheduling finishes, to the almost not influence of scheduling of packet on the default bearing.Up-downgoing can reach peak rate.
The embodiment of the invention is through core-network side configuration PCC rule; Realized that the tcp data bag transmits in different carryings with the TCP respond packet; And TCP ACK/NACK respond packet is carried on the dedicated bearer of high priority (be dispatching priority high), thereby a kind of method of lifting message transmission rate is provided.
The embodiment of the invention has improved single user and has carried out the up-downgoing of the FTP FTP downlink business speed when professional simultaneously, has promoted user's perception, has increased resource utilization ratio and throughput.Only need set up dedicated bearer according to the downlink business five-tuple of FTP.In practical application, core net has been disposed the PCRF system, and core network element P-GW possessed the DPI function, satisfies the condition of setting up of special feature (dedicated bearer).
The embodiment of the invention provides the professional data transmission device of transmission control protocol TCP among a kind of mobile network, as shown in Figure 8 comprising:
The carrying control module 802 of said apparatus is after setting up second type of carrying; Specifically be used for; Carry professional and above-mentioned other the packet of TCP business of the current TCP of transmission through first kind; Perhaps, carry professional and above-mentioned other the professional packet of TCP of the current TCP of transmission through a plurality of first kind, and each first kind is carried the packet of at least one current TCP business of transmission;
And; Specifically be used for carrying professional and above-mentioned other the respond packet of TCP business of the current TCP of transmission through one second type; Perhaps; Transmit professional and above-mentioned other the professional respond packet of TCP of current TCP respectively through a plurality of second type of carrying, and each second type respond packet of carrying at least one current TCP business of transmission.
The above-mentioned first kind is carried can be the default bearing of dialogue-based port, and second type of carrying can be the dedicated bearer based on preset port.
When said apparatus is applied in the ftp business in the TCP business, carry control module 802 according to working method at ftp business, select the mode of setting up of corresponding second type of carrying, comprising:
When the working method of ftp business is active mode, set up corresponding second type of carrying according to Internet protocol IP five-tuple information;
When the working method of ftp business is passive mode:
If can confirm the port range that server uses, the port range that then uses according to server is set up corresponding second type of carrying;
If be not sure of the port range that server uses; Then set up corresponding second type of carrying according to the packet of ftp business and the analysis result of respond packet; For example, based on the DPI function, resolve the FTP data traffic flows; Identification FTP data download bag and feedback packet, thereby the port range of definite dedicated bearer.
When a plurality of TCP business are transmitted data simultaneously in the prior art; The scheduling of the respond packet that one of them TCP is professional may come after the professional packet of other TCP; Because the transmission time of packet is long more a lot of than respond packet; The professional respond packet of this TCP need wait for that the data packet transmission of its front finishes like this, and time to be transmitted such as respond packet is much long like this.
The embodiment of the invention is carried out a plurality of TCP when professional simultaneously in client-requested, be higher than second type of carrying that the first kind is carried through setting up dispatching priority, and the respond packet that all TCP are professional is through transmitting in second type of carrying; Make respond packet in time to be scheduled, because when a plurality of TCP business are carried out transfer of data simultaneously, compared to the transmission rate of packet; The professional respond packet transmission rate of TCP wants much fast; Therefore, the transmission time of the respond packet of in the higher dedicated bearer of dispatching priority, transmitting is very short, and respond packet can be by priority scheduling; Be that respond packet is transmitted earlier than packet all the time, need do not wait for the long time.This shows; When a plurality of TCP business are carried out transfer of data simultaneously in the embodiment of the invention; The mutual influence of a plurality of TCP traffic transmission speed is less; And the embodiment of the invention has solved when a plurality of TCP are professional in the prior art transmits in same carrying simultaneously, does not cause the problem of TCP traffic transmission speed decline owing to respond packet in time is scheduled.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
