Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme of the embodiment of the invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.The every other embodiment that described embodiment in according to the present invention, those skilled in the art obtain under the prerequisite of not making creative work should belong to the scope of protection of the invention.
At first, in conjunction with the method 100 of Fig. 1 description according to the transfer of data of the embodiment of the invention.
As shown in Figure 1, method 100 comprises: S110, obtain the data attribute of down user data; S120 sends down user data and data attribute to access network equipment so that access network equipment according to service quality corresponding to data attribute to the transmission down user data that accesses terminal.
For example, method 100 can be carried out by PDSN.PDSN is the gateway device of AT accessing group data net.PDSN receives the down user data that sends to AT from Packet Data Network, and down user data is passed to after the AN equipment, sends to AT by AN equipment by wireless channel.
In S110, PDSN obtains data attribute, thereby can be by data attribute to the required service quality of the AN equipment indication corresponding down user data of transmission.For example, by data attribute can be simultaneously to maximum transmission bandwidth and the minimum transfer bandwidth of AN equipment indicating downlink user data, then AN equipment can be controlled the transmission rate of down user data, so that the requirement of described maximum transmission bandwidth and minimum transfer bandwidth is satisfied in the transmission of down user data.
According to one embodiment of present invention, data attribute can comprise the type of service of down user data.Type of service can be called as application type again.Can identify corresponding service by type of service.Since different business can be corresponding at AN equipment place different service quality (for example, transmission requirement), when AN equipment was received data attribute, AN equipment can be determined therewith service quality corresponding to type of service according to the type of service in the data attribute.
For example, for point-to-point (Point-to-Point, P2P) business, the 0001H value can be set indicate this type of service; For HTML (Hypertext Markup Language) (HyperText Transfer Protocol, HTTP) business, the 0002H value can be set indicate this type of service; For online speech business, the 0003H value can be set indicate this type of service.For the type of service of P2P business, by the 0001H service class indication, this type of service service quality corresponding at AN equipment place is to satisfy the requirement of maximum transmission bandwidth and minimum transfer bandwidth; For the type of service of HTTP business, by the 0002H service class indication, this type of service service quality corresponding at AN equipment place gets final product for satisfying the requirement of doing one's best; For the type of service of online speech business, by the 0003H service class indication, the requirement that this type of service service quality corresponding at AN equipment place is shaken for satisfying maximum delay and maximum delay.Certainly, those skilled in the art it will also be appreciated that the service quality that need to satisfy for other types of service.
PDSN can obtain the type of service of down user data in several ways, thereby the type of service of obtaining can be passed to the service quality that AN equipment indicates transmission to satisfy.
For example, PDSN can according to the header information of the packet that carries down user data, obtain the type of service of down user data.
PDSN carries the down user data that need to send to AT from Packet Data Network's receive data bag in packet.In the head of packet, carry the parameter informations such as destination address, source address, destination slogan, source port number and protocol number, can determine type of service under the down user data by header information.For example, certain specific transactions from the down user data correspondence of particular source and source port number; Or the down user data correspondence that is delivered to the specific purpose address and has a specific protocol number certain specific transactions etc.
Again for example, PDSN can by the packet that carries down user data is wrapped depth detection, obtain the type of service of down user data.
PDSN can detect the packet that carries down user data with existing bag depth detection technology, thereby can obtain type of service.
Again for example, PDSN can obtain from other network equipments the type of service of down user data.
If above-mentioned other network equipments are not the network equipments that generates down user data, then these other network equipments can obtain type of service from the header information of the packet that carries down user data, also can obtain type of service by bag depth detection technology, the type of service of then oneself being obtained passes to PDSN.If above-mentioned other network equipments are the network equipments that generate down user data, then it can directly be notified the type of service of down user data to PDSN.
According to one embodiment of present invention, data attribute can comprise QoS parameter.QoS parameter can be used to indicate at least one in priority, maximum delay, maximum delay shake, minimum transfer bandwidth and the maximum transmission bandwidth of processing down user data.Although listed the part in the QoS parameter at this, do not got rid of QoS parameter and can also indicate other transmission requirement.
PDSN can obtain the QoS parameter of down user data in the following way: the type of service of obtaining down user data; According to type of service, determine the QoS parameter of down user data.As mentioned above, PDSN can utilize the header information of the packet that carries down user data to obtain the type of service of down user data, also can utilize deep packet inspection technical to obtain the type of service of down user data, can also obtain from other network equipments the type of service of down user data.
PDSN obtains after the type of service, can determine according to type of service the QoS parameter of down user data.For example, when the type of service of obtaining down user data as PDSN was video conference business, PDSN can determine that this down user data has the highest priority, and then PDSN passes to AN equipment with high priority as data attribute.When the type of service of obtaining down user data as PDSN was file downloading service, PDSN can determine that the priority of this down user data is low and insensitive to time delay, and then PDSN will do one's best or low priority passes to AN equipment as data attribute.
PDSN also can obtain from other network equipments the QoS parameter of down user data.
As mentioned above, other network equipments in the network can obtain the type of service of down user data, for example can obtain type of service from the header information of the packet that carries down user data, also can obtain type of service by bag depth detection technology.After other network equipments obtained the type of service of down user data, this network equipment can be determined according to type of service the QoS parameter of down user data, and then the QoS parameter with down user data passes to PDSN.
PDSN obtains after the QoS parameter of down user data, and this QoS parameter is passed to AN equipment as data attribute.
In S120, PDSN has obtained after the data attribute, and data attribute and down user data are sent to AN equipment, so that AN equipment is determined corresponding service quality according to data attribute, transmits down user data according to this service quality.
For example, PDSN can at first send to the PCF entity by down user data and data attribute are carried in the Frame, transmits via the PCF entity, so that down user data and data attribute are passed to AN equipment again.In some cases, for example, when the function of PCF entity was integrated in the AN equipment, PDSN also can directly send to AN equipment with down user data and data attribute.In addition, PDSN also can be transmitted to AN equipment with down user data and data attribute by other network equipments.
According to one embodiment of present invention, PDSN can be carried at data attribute in the attribute field of GRE frame and send to the PCF entity, so that the PCF entity is transmitted to AN equipment with data attribute.
For example, PDSN can be carried at down user data in the customer service field of GRE frame, data attribute is carried in the attribute field of GRE frame, thereby by the GRE frame down user data and data attribute is passed to the PCF entity.The PCF entity extracts down user data and data attribute from the GRE frame, be encapsulated as new GRE frame again, passes to AT.
When data attribute was type of service, PDSN can pass to type of service AN equipment, determines corresponding service quality by AN equipment according to type of service, thereby transmits according to this service quality.
When data attribute is QoS parameter, PDSN obtains after the type of service, determine QoS parameter according to type of service, again the QoS parameter of determining is passed to AN equipment, transmitted according to service quality corresponding to QoS parameter by AN equipment.
The QoS parameter that PDSN transmits can be the direct parameter relevant with service quality, for example process at least one in priority, maximum delay, maximum delay shake, minimum transfer bandwidth and the maximum transmission bandwidth of down user data, AN equipment can directly be determined corresponding transmission requirement according to this QoS parameter.The QoS parameter that PDSN transmits also can be that the parameter relevant with service quality numbered accordingly, for example, each corresponding numbering of priority, maximum delay, maximum delay shake, minimum transfer bandwidth and maximum transmission bandwidth, can comprise in the QoS parameter with priority, maximum delay, maximum delay shake, minimum transfer bandwidth and maximum transmission bandwidth at least one corresponding numbering, after AN equipment is received this QoS parameter, can determine by numbering the quality of service requirement of this down user data of transmission.
Therefore, PDSN can pass through type of service, also can pass through QoS parameter, come the IP stream that same data connected in mode neatly or the business datum on the same IP stream to distinguish, so that access network equipment can take to satisfy to different down user datas the transmission means of corresponding quality of service requirement, thereby improve user's communication experiences.
Because data attribute can be carried in the attribute field of GRE frame, therefore can be compatible mutually with the Frame of existing transmission down user data, in the form of available data frame, carry data attribute easily, very little on existing message structure impact, realize easy.
The form of GRE frame as shown in Figure 2.C field, r field, K field, S field, reservation (Reserved) field, version (Ver) field, protocol type (Protocol Type) field, keyword (KEY) field, sequence number (Sequence Number) field are identical with usage of the prior art.Down user data is carried in customer service (User Traffic) field of GRE frame.
The GRE frame can have a plurality of attributes (Atributes) field.The GRE frame can not carry attribute field in the prior art, but in embodiments of the present invention, for the service quality to AN equipment indicating downlink user data, need to utilize an attribute field, so that the GRE frame has an attribute field at least.Can in attribute field, carry data attribute by form as shown in Figure 3.
As shown in Figure 3, attribute field comprises E control field, type (Type) field, length (Length) field and value (Value) field.
For example, when the attribute field that carries data attribute was last attribute field of GRE frame, the E control field was 1, otherwise was 0.
Type field is used for this attribute field of expression and has carried data attribute.Type field can be predefined value, distinguishes mutually by this value and other attributes.For example, can type field being set to " 0000101 " represents to carry data attribute in this attribute field.The value of type field just illustrates herein, is not limited to the span of type field, as long as can be distinguished this attribute field and existing attribute mutually.
Length field is used for the length of this attribute field of expression, and unit can be byte, and the numerical value of length field can be set according to the concrete numerical value that the value field is carried.
The value field is used for carrying concrete data attribute, and this field occupies the byte on 2 or 2 usually.For example, when data attribute was type of service, the value field was got 0001H and is represented the P2P business, and get 0002H and represent the HTTP business, etc.; When data attribute was QoS parameter, the value field was got 0003H and is represented highest point reason priority, got the transmission bandwidth that the 0004H representative is 5M to the maximum, and getting 0005H, to represent maximum delay be 2 seconds, etc.
According to one embodiment of present invention, PDSN can after definite access network equipment has the ability of supported data attribute, carry out S120 again; PDSN also can after definite access network equipment has the ability of supported data attribute, carry out S110 and S120 again.
Through consultation, PDSN can know AN equipment supported data attribute between PDSN, PCF, the AN equipment, so PDSN is by indicating AN equipment to operate accordingly to AN equipment sending data attribute, to satisfy service quality corresponding to data attribute.
The method of the transfer of data that provides according to the embodiment of the invention is by send the data attribute of down user data to access network equipment, so that access network equipment can take to meet according to service quality corresponding to data attribute the transmission means of quality of service requirement.Like this, the problem that can avoid in the prior art the service quality of the IP stream that can not connect same data or the different down user datas in the same IP stream to distinguish, therefore can carry out further refinement to the service quality of different down user datas, so that can provide according to the service quality of down user data corresponding transmission service, thereby can improve user's communication experiences.
Next, specifically describe method according to the transfer of data of the embodiment of the invention in conjunction with the example of the network architecture shown in Figure 4.
In Fig. 4, setting up between PDSN and PCF has A10 to be connected with A11 to be connected, by A10 connection transmitting user data, by A11 connection command transmitting information.Setting up between PCF and AN equipment has the A8 connection to be connected with A9.Connect transmitting user data by A8, connect command transmitting information by A9.For same AT, can have a plurality of RLP (the Radio Link Protocol between a plurality of A8 connections, a plurality of A10 connection and this AT and the AN equipment, radio link protocol) data flow, that is to say, can have a plurality of data to connect between PDSN and AT, each data connects and comprises that an A10 connects, an A8 connects and a RLP data flow.On connecting, each data can carry a plurality of IP traffics.Prior art can not be distinguished the QoS of the IP traffic in each data connection, can not distinguish the QoS of different business in the same IP stream, by utilizing the method for the transfer of data that the embodiment of the invention provides, the QoS of the different business in can flowing IP stream, the same IP of the upper carrying of each data connection carries out further refinement, thereby improves user's communication experiences.
In S410, PDSN sends down user data by the GRE agreement to PCF in the A10 connection, carries data attribute in the GRE frame, can make AN equipment determine the service quality of down user data by data attribute.Data attribute can be the type of service of down user data, also can be QoS parameter.Hereinafter, will connect the GRE frame that transmits at A10 and be called A10 connection GRE frame.
In S420, PCF is after the A10 connection receives that A10 connects the GRE frame, and PCF extracts down user data and data attribute from A10 connection GRE frame, repack the GRE frame that is created on transmission in the A8 connection, and this GRE frame is sent to AN equipment.Hereinafter, will connect the GRE frame that transmits at A8 and be called A8 connection GRE frame.
In S430, AN equipment connects at A8 receives that the A8 that PCF sends connects the GRE frame, connect the data attribute that carries in the GRE frame by resolving A8, namely A10 connects the data attribute that carries in the GRE frame, can determine to transmit the service quality that down user data need to satisfy.
In S440, AN equipment connects the down user data that carries in the GRE frame according to the service quality that above-mentioned definite down user data needs satisfy with A8, and namely A10 connects the down user data that carries in the GRE frame, sends to AT.
For instance, for example, when data attribute was type of service, for the professional corresponding down user data of P2P, AN equipment carried out flow restriction; For the professional corresponding down user data of web browsing, AN equipment is carried out priority scheduling etc.In addition, AN equipment can carry out the allotment of radio channel resource by the reference type of service, for example, only has instant messaging if AT is current, and AN equipment can make AT enter Idle state etc. after data are sent completely quickly.When data attribute was QoS parameter, for the down user data of low priority, AN equipment carried out flow restriction, and for high processing priority, AN equipment is carried out priority scheduling, etc.
To AN equipment indication service quality, except the communication experiences that can improve the user, all right coordination network is to the transmittability of different business by data attribute for PDSN.For example, when needing while supporting document downloading service and web page browsing professional in same data connection, if file downloading service at first occurs, so limited Internet resources are the supporting document downloading service at first, web page browsing for follow-up generation is professional, may not in time respond, thereby for the user who waits for browsing page brings larger time delay, affect this user's communication experiences.At this moment, PDSN can be by to AN equipment sending data attribute, indicates AN equipment with the limit bandwidth of supporting document downloading service within limits, thereby can reserve a part of bandwidth supported web page browse service, realizes both coordinations.
In addition, PDSN and PCF can initiate a negotiations process by the A11 interface, learn whether the other side has the ability of supported data attribute, and whether PCF can have AN equipment the information of the ability of supported data attribute is notified to PDSN.PCF and AN equipment can be initiated a negotiations process by the A9 interface, learn whether the other side has the ability of supported data attribute, and whether PCF can have PDSN the informing capability of supported data attribute to AN equipment.Like this, by PCF, PDSN can know the ability whether AN equipment has the supported data attribute.
Finally, PDSN has at AN equipment in the situation of ability of supported data attribute, can satisfy corresponding quality of service requirement when data attribute is indicated AN device transmission down user data by carrying in the GRE frame.Wherein, the implication of data attribute is that PDSN and AN equipment are all known, the implication of data attribute can be pre-arranged in PDSN and AN equipment, also can be in negotiations process PDSN and AN equipment reach an agreement.Certainly, because negotiations process can relate to the PCF entity, therefore, the implication of data attribute also can be pre-arranged in the PCF entity, can also be known by the PCF entity in negotiations process.
Next, in conjunction with the method 500 of Fig. 5 description according to the transfer of data of the embodiment of the invention.
As shown in Figure 5, method 500 comprises: S510 receives down user data and data attribute from packet data serving node; S520, the service quality corresponding according to data attribute is to the transmission down user data that accesses terminal.
For example, method 500 can be carried out by AN equipment.Because the operation of AN equipment is corresponding with the operation of PDSN equipment, so the corresponding description that the related content of method 500 can reference method 100.
