The policy entity, which is sent, deactivates DSCP marking conventions to the fixed network node, so that the fixed network node is whole to the movement The packet-switched traffic at end deactivate the processing of DSCP marking conventions；

Or, when the policy entity detects the IP-CAN conversation ends between the policy entity and the PCRF, transmission is gone DSCP marking conventions are activated to the fixed network node, so that the fixed network node is gone to the packet-switched traffic of the mobile terminal Activate the processing of DSCP marking conventions.

Now, the policy entity, which sends the DSCP marking conventions or sent, deactivates DSCP marking conventions to fixed network Node BNG and/or TWAG are specially：For local unloading data flow or packet-switched traffic, policy entity by and fixed network Node BNG interface（Such as R interfaces or Gxd interfaces）The DSCP marking conventions or deactivation DSCP marking conventions are sent To fixed network node BNG；Or, for the local unloading data flow or packet-switched traffic under the credible access scenes of WLAN, Policy entity passes through the interface with fixed network node TWAG（Current invention assumes that being P interfaces）By the DSCP marking conventions or deactivation DSCP marking conventions are sent directly to fixed network node TWAG；Or, the scene separated for TWAG in the credible accesses of WLAN and BNG Under local unloading data flow or packet-switched traffic, policy entity passes through will be described with fixed network node BNG interface DSCP marking conventions or deactivation DSCP marking conventions are sent to fixed network node BNG, then are further passed through by fixed network node BNG Interface between BNG and TWAG（The present invention is set to X interfaces）By DSCP marking conventions or deactivate DSCP marking conventions send to Fixed network node TWAG；Or, for the packet-switched traffic under the credible access scenes of WLAN, the policy entity passes through movement S2a interfaces between packet data gateway and TWAG send the QCI information of carrying to TWAG, so that QCIs of the TWAG according to carrying Information carries out DSCP marks to the packet-switched traffic.

Method more than, fixed network node BNG and/or TWAG can obtain Rule Information or the deactivation of DSCP marks DSCP marking conventions, to perform the mark of DSCP values on BNG and/or TWAG.

As another example of the invention, when policy entity is fusion DNA vaccine F, step S101 specifically includes following step Suddenly：

Fusion DNA vaccine F and fixed network node BNG sets up IP-CAN sessions；

When obtain data stream type to should mobile terminal local unloading data flow when, fusion DNA vaccine F generates and sends With the corresponding DSCP marking conventions of local unloading data flow to the fixed network node BNG and/or TWAG, so that the fixed network node BNG and/or TWAG carries out DSCP marks according to the DSCP marking conventions to the local unloading data flow；

When acquisition data stream type to should fixed network equipment data flow when, fusion DNA vaccine F generates and sends solid with this The corresponding DSCP marking conventions of data flow of net equipment are to fixed network node BNG, so that the fixed network node BNG is marked according to the DSCP Note rule, the data flow to the fixed network equipment carries out DSCP marks；

Or, set up and be connected with mobile packet data gateway in the mobile terminal, and the fusion DNA vaccine F and BNG sets up net Close control session after, fusion DNA vaccine F obtain data stream type to should mobile terminal packet-switched traffic, generation simultaneously DSCP marking conventions corresponding with the packet-switched traffic are sent to the fixed network node BNG and/or TWAG, so that the fixed network section Point BNG and/or TWAG carries out DSCP marks according to the DSCP marking conventions to the packet-switched traffic.

Wherein, the type of data flow can be based on description of data stream information or based on other acquisition of information, for example, Data route in the conversation type information set up between APN identification informations, fixed network node BNG or TWAG and PCRF, PCRF Information etc..Returned in real time for fusion DNA vaccine F with the corresponding DSCP marking conventions of local unloading data flow with the local unloading The corresponding DSCP marking conventions of data flow, or reply or change entrained in message for the IP connection network access session establishment DSCP marking conventions；DSCP marking conventions corresponding with the description of data stream information of the fixed network equipment are that fusion DNA vaccine F is real-time The DSCP marking conventions corresponding with the data flow of the fixed network equipment returned, or returned for the IP connection network access session establishment Entrained DSCP marking conventions in multiple or modification message；DSCP marking conventions corresponding with the packet-switched traffic melt for this The DSCP marking conventions corresponding with the packet-switched traffic that PCRF is returned in real time are closed, or for the gateway control session is built It is vertical to reply or change DSCP marking conventions entrained in message.

Now, the fusion DNA vaccine F sends the DSCP marking conventions to fixed network node BNG and/or TWAG and is specially：It is right In locally unloading data flow or packet-switched traffic or fixed network device data stream, fusion DNA vaccine F by with fixed network node BNG Interface（Such as Gxd interfaces）The DSCP marking conventions or deactivation DSCP marking conventions are sent to fixed network node BNG； Or, for WLAN it is credible access scene under local unloading data flow or packet-switched traffic, fusion DNA vaccine F by with Fixed network node TWAG interface（The present invention is set to K interfaces）By the DSCP marking conventions or deactivation DSCP marking convention hairs Deliver to fixed network node TWAG；Or, the local unloading data flow under the scene separated for TWAG in the credible accesses of WLAN and BNG Or packet-switched traffic, fusion DNA vaccine F passes through the interface with fixed network node BNG（Such as Gxd interfaces）The DSCP is marked Rule or deactivate DSCP marking conventions send to fixed network node BNG, fixed network node BNG further by BNG and TWAG it Between interface（The present invention is set to X interfaces）DSCP marking conventions or deactivation DSCP marking conventions are sent to fixed network node TWAG；Or, for the packet-switched traffic under the credible access scenes of WLAN, the fusion DNA vaccine F passes through mobile packet data S2a interfaces between gateway and TWAG send the QCI information of carrying to TWAG so that TWAG according to the QCI information of carrying to institute State packet-switched traffic and carry out DSCP marks.

In step s 102, the fixed network node performs DSCP according to the DSCP marking conventions received to target data stream Mark.

Because the DSCP marking conventions can serve to indicate that fixed network node according to DSCP pre-configured on the fixed network node The DSCP mapping tables indicated in real time in mapping table or DSCP marking conventions, carry out DSCP marks, or refer to target data stream Show fixed network node by target data stream labeled as the DSCP corresponding to indicated DSCP values either indicated QCI values or Indicate that fixed network node keeps the DSCP values of target data stream constant etc., then step S102 is specially：

The fixed network node carries out the mapping of DSCP values according to the DSCP mapping tables to each packet of the target data stream, Or the DSCP values of each data flow are marked as the DSCP for directly indicating or being indicated indirectly by QCI values by DSCP values Value, or keep the DSCP values of the target data stream constant.

In embodiments of the present invention, the policy entity is BPCF, fusion DNA vaccine F or other plans comprising the BPCF functions When omiting entity, progress of the corresponding specific DSCP marks processing procedure in following embodiments two, embodiment three, the embodiment fourth class Describe in detail, will not be repeated here.

In embodiments of the present invention, the DSCP mark rule that the data flow of current accessed is marked are issued by policy entity Then, corresponding DSCP marking conventions can be sent for different data flows, fixed network node is only needed to according to coming from for receiving The DSCP marking conventions that policy entity is sent, it is possible to DSCP values are carried out to corresponding data flow and marked so that fixed network node is clear Chu Zhidao is to mobile terminal or the DSCP marking conventions of the different data streams of fixed network equipment, hence for each of the data flow The DSCP values in IP packet header are suitably handled, and are simplified the processing logic of residential gateway, are also improved fixed network node pair The flexibility of DSCP values mark.

Embodiment two：

Fig. 2 shows the implementation process of the mark processing method for the DSCP that second embodiment of the invention is provided, and specially works as ,, should so that fixed network node is BNG as an example when the equipment accessed by fixed network is mobile terminal when policy entity is BPCF DSCP mark processing method implements process, and details are as follows：

In the step s 21, mobile terminal sends access network request by fixed network domain to HSS/AAA servers.

In step S22, the BNG in the fixed network domain carries out access authentication to the mobile terminal.

Specifically, the BNG can carry out EAP-AKA certification to the mobile terminal, and the EAP-AKA is to be applied to 3G network Authentication and key distribution protocol, and after the authentication has been successful, the mobile terminal is with will obtaining the native ip network of distribution Location.

In step S23, after the authentication has been successful, the BNG sends triggering to BPCF and sets up IP connection network access sessions Message.

In step s 24, the BPCF is according to the message, and it is local unloading data stream type to obtain current data stream type, And set up IP with PCRF and be connected network access session.

In step s 25, the PCRF sends DSCP marking conventions corresponding with local unloading data flow into the BPCF.

Wherein, the DSCP marking conventions can be the mapping table needed for indicating DSCP marks or the DSCP values after cue mark Deng.Specifically, the PCRF is provided in the PCC rules for local unloading data flow, the rule comprising related DSCP mark plans Slightly, then the PCC rules are issued to BPCF by the PCRF.Certain PCRF can also be directly by DSCP labelling strategies and PCC rules It is issued to BPCF parallel.

In step S26, the BPCF receives the DSCP marking conventions, and the DSCP marking conventions are sent to the BNG, with The BNG is set to carry out DSCP marks to the local unloading data flow of the mobile terminal.

In specific implementation process, it is successfully established in the BPCF and PCRF after IP is connected network access session, the IP connections DSCP marking conventions can be carried in network access session, so that the BPCF can also be directly from the IP connection network access sessions Management（Set up reply, modification etc.）DSCP marking conventions corresponding with local unloading data flow are obtained in message in real time, to trigger BNG carries out the function of DSCP marks to the local unloading data flow of mobile terminal.Specifically, the DSCP marking conventions can include The PCC rules comprising DSCP marking conventions are issued in BPCF in PCC rules, namely by the PCRF, so that the BPCF roots According to PCC Rules DSCP marking conventions corresponding with local unloading data flow；Or the DSCP marking conventions can also be made Used for independent individual, namely DSCP marking conventions corresponding with locally unloading data flow are directly issued to BPCF by PCRF In, so that the BPCF can directly forward DSCP rules into BNG, it can specifically be preset according to actual conditions.Enter one Step ground, the instruction DSCP mark needed for mapping table can the QCI according to rule set up mark indicate, if the PCC rule in QCI rules are not contained, but directly include the DSCP values after cue mark, namely root has been carried out in advance on BPCF or PCRF DSCP values after being marked according to QCI Rules, then BNG is after the DSCP values after receiving the cue mark, directly to mobile whole Each local unloading data flow at end carries out DSCP mark.

In step s 27, the mobile terminal is set up with mobile packet data gateway PDN GW and is connected.

In step S28, PDN GW triggerings set up IP with the PCRF and are connected network access session.

Wherein, the IP connection network access session is different from connection between BPCF and PCRF in step S23, but with shifting The PS packet switched data of dynamic terminal accesses related.

In step S29, PCRF triggerings set up gateway control session with the BPCF.

In step S210, the PCRF issues DSCP marking conventions corresponding with packet-switched traffic into the BPCF.

In step S211, the BPCF receives the DSCP marking conventions, and the DSCP marking conventions are sent to the BNG, So that the BNG carries out DSCP marks to the packet-switched traffic of the mobile terminal.

Wherein, as step S29, S210, S211 alternate example, separated for WLAN credible access TWAG and BNG Packet-switched traffic under scene, PCRF can also by the S2a interfaces between mobile packet data gateway and TWAG to TWAG sends the QCI information of carrying, so that TWAG carries out DSCP marks according to the QCI information of carrying to the packet-switched traffic Note.

Specifically, the PCRF can provide packet switching service data related QoS rules to the BPCF, and the QoS is advised Then it is issued in the BPCF, now includes DSCP marking conventions corresponding with packet-switched traffic in QoS rules, then should BPCF is according to QoS Rules DSCP marking conventions corresponding with packet-switched traffic；Or DSCP marking conventions also may be used DSCP marking conventions corresponding with packet-switched traffic are directly issued to be used as independent individual, namely by PCRF extremely In BPCF, so that the BPCF can directly forward DSCP rules to BNG.

In specific implementation process, after step S29, BPCF is triggered to BNG and is sent gateway control session management（Including Set up reply, modification etc.）Message, the message includes DSCP marking conventions or DSCP mappings are indicated, and packet switch number According to the description information of stream（For example using mobile terminal and EPDG address as five-tuple address information）Deng to trigger BNG activation pair The data flow that mobile terminal carries out packet-switched access indicates to carry out DSCP values mark etc. according to mapping.

Further, local unloading data flow under the scene separated for TWAG in the credible accesses of WLAN and BNG or Packet-switched traffic, BPCF can be sent DSCP marking conventions to fixed network node by the interface with fixed network node BNG BNG, fixed network node BNG can further be sent DSCP marking conventions to fixed network node by the interface between BNG and TWAG TWAG.Now, the DSCP marking conventions can directly be the DSCP marking conventions that BNG is received from PCRF in above-mentioned steps S211, Can also be the new DSCP rules further generated based on the DSCP marking conventions in above-mentioned steps S211.

In embodiments of the present invention, changing for subscription data such as, is detected due to the triggering of some conditions on the PCRF Change, the change of network congestion condition, the change of the remaining amount of user, the local policy on PCRF because detect some spies Different data flow etc., then can update and be issued to DSCP marking conventions, then the DSCP that the BPCF is received be labeled as obtain in real time, Newest DSCP marking conventions, so as to it is more flexible, exactly issue marking convention.Namely the BPCF can in real time to BNG and/or TWAG sends DSCP marking conventions, so that BNG and/or TWAG activation is carried out to the related data flow of mobile terminal DSCP values are marked.In addition, the DSCP marking conventions can also be included in PCC rules or QoS rules, the rule are received in BNG After then, the mark in PCC rules or QoS rules is indicated, activates what is be pre-configured with BNG with the granularity of every terminal Specific DSCP marks mapping table etc., the concrete mode of mark includes carrying out DSCP mappings, basis one by one to each IP packets The DSCP values of QCI value flag data streams, holding DSCP are constant or the DSCP values of corresponding data stream are marked as to indicated value Deng.

In embodiments of the present invention, when policy entity is other policy entities comprising the BPCF functions, it will can wrap Other policy entities containing the BPCF functions substitute the above-mentioned BPCF, realize BNG or TWAG to data flow by above-mentioned steps DSCP marks processing etc. operation, will not be repeated here.
