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

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 generate simultaneously Send with the local corresponding DSCP marking conventions of data flow that unload to the fixed network node BNG and/or TWAG, so that fixed network node BNG and/or TWAG is according to the DSCP Marking convention, DSCP marks are carried out 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 and the fixed network equipment The corresponding DSCP marking conventions of data flow to fixed network node BNG so that the fixed network node BNG is according to the DSCP marking conventions, the data flow to the fixed network equipment carries out DSCP Mark；

Or, set up and be connected with mobile packet data gateway in the mobile terminal, and the fusion DNA vaccine F and BNG Set up after gateway control session, fusion DNA vaccine F obtain data stream type to should mobile terminal packet-switched traffic, generate and send DSCP marking conventions corresponding with the packet-switched traffic to the fixed network node BNG and/or TWAG, so that fixed network node 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, APN identification informations, fixed network node Data routing iinformation in the conversation type information set up between BNG or TWAG and PCRF, PCRF etc..It is fusion DNA vaccine F with the corresponding DSCP marking conventions of local unloading data flow Return in real time with the corresponding DSCP marking conventions of local unloading data flow, or the DSCP marking conventions entrained by for the IP connection network access session establishment replying or change in message；With the fixed network equipment The corresponding DSCP marking conventions of description of data stream information be the DSCP marking conventions corresponding with the data flow of the fixed network equipment that return in real time of fusion DNA vaccine F, or be the IP Connect network access session establishment and reply or change DSCP marking conventions entrained in message；DSCP marking conventions corresponding with the packet-switched traffic are fusion DNA vaccine F The DSCP marking conventions corresponding with the packet-switched traffic returned in real time, or reply or change DSCP marking conventions entrained in message for the gateway control session is set up.

Now, the fusion DNA vaccine F sends the DSCP marking conventions to fixed network node BNG and/or TWAG Specially：For local unloading data flow or packet-switched traffic or fixed network device data stream, fusion DNA vaccine F passes through the interface with fixed network node BNG（Such as Gxd interfaces）By the DSCP Marking convention 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, fusion DNA vaccine F Pass through the interface with fixed network node TWAG（The present invention is set to K interfaces）The DSCP marking conventions or deactivation DSCP marking conventions are sent to fixed network node TWAG；Or, for Local unloading data flow or packet-switched traffic in access that WLAN is credible under the scene of TWAG and BNG separation, fusion DNA vaccine F pass through the interface with fixed network node BNG（Such as Gxd Interface）The DSCP marking conventions or deactivation DSCP marking conventions are sent to fixed network node BNG, fixed network node BNG and further pass through BNG and TWAG 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 WLAN Packet-switched traffic under credible access scene, the fusion DNA vaccine F sends the QCI information of carrying by the S2a interfaces between mobile packet data gateway and TWAG to TWAG, so that TWAG carries out DSCP marks according to the QCI information of carrying to the packet-switched traffic.

In step S102, the fixed network node performs DSCP according to the DSCP marking conventions received to target data stream Mark.

Due to the DSCP marking conventions can serve to indicate that fixed network node according to DSCP mapping tables pre-configured on the fixed network node or The DSCP mapping tables indicated in real time in DSCP marking conventions, DSCP marks are carried out to target data stream, or indicate that target data stream is labeled as indicated DSCP values or indicated by fixed network node The corresponding DSCP of 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 DSCP according to the DSCP mapping tables to each packet of the target data stream Value mapping, is either marked as this by the DSCP values of each data flow and passes through the direct DSCP values for indicating or being indicated indirectly by QCI values of DSCP values or the DSCP for keeping the target data stream Value is constant.

In embodiments of the present invention, the policy entity is BPCF, fusion DNA vaccine F or includes the BPCF During other policy entities of function, corresponding specific DSCP marks processing procedure being described in detail in following embodiments two, embodiment three, the embodiment fourth class will not be repeated here.

In embodiments of the present invention, the DSCP that the data flow of current accessed is marked is issued by policy entity Marking convention, can send corresponding DSCP marking conventions for different data flows, and fixed network node is only needed to according to the DSCP marking conventions sent from policy entity received, it is possible to which corresponding data flow is carried out DSCP values are marked so that fixed network node is clear from the DSCP marking conventions of the different data streams to mobile terminal or fixed network equipment, hence for the DSCP in each IP packet header of the data flow Value is suitably handled, and simplifies the processing logic of residential gateway, also improves the flexibility that fixed network node is marked to DSCP values.

Embodiment two：

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

In step S21, 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 The authentication of network and key distribution protocol, and after the authentication has been successful, the mobile terminal will obtain the local IP network address of distribution.

In step S23, after the authentication has been successful, the BNG sends triggering to BPCF and sets up IP Connect the message of network access session.

In step S24, the BPCF is according to the message, and it is local unloading data stream type to obtain current data stream type, and with PCRF sets up IP connection network access sessions.

In step S25, 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 DSCP values after cue mark etc.. Specifically, the PCRF is provided in the PCC rules for local unloading data flow, the rule and is included related DSCP labelling strategies, then the PCC rules are issued to BPCF by the PCRF .DSCP labelling strategies and PCC rules directly can also be issued to BPCF by certain PCRF parallel.

In step S26, the BPCF receives the DSCP marking conventions, and the DSCP marking conventions are sent to this BNG, so that the BNG carries 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 DSCP marking conventions can be carried in connection network access session, so that the BPCF can also be directly from the IP Connect network access session management（Set up reply, modification etc.）DSCP marking conventions corresponding with local unloading data flow are obtained in message in real time, DSCP is carried out to the local unloading data flow of mobile terminal to trigger BNG The function of mark.Specifically, the DSCP marking conventions can be included in PCC rules, namely the PCC rules comprising DSCP marking conventions are issued into BPCF by the PCRF In, so that the BPCF is according to PCC Rules DSCP marking conventions corresponding with local unloading data flow；Or the DSCP marking conventions can also be used as independent individual, namely by PCRF DSCP marking conventions corresponding with locally unloading data flow are directly issued into BPCF, so that the BPCF can directly forward DSCP rules to BNG In, it can specifically be preset according to actual conditions.Further, the instruction DSCP mark needed for mapping table can the QCI according to rule set up mark indicate, if the PCC rule in do not contain QCI Rule, but the DSCP values after cue mark are directly included, namely carried out in advance according to the DSCP values after QCI Rules mark, then BNG on BPCF or PCRF After the DSCP values after receiving the cue mark, each local unloading data flow directly to mobile terminal carries out DSCP mark.

In step S27, 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 BPCF and PCRF in step S23 Between connection, it is but related to the PS packet switched data access of mobile terminal.

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 this 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, for the credible access TWAG of WLAN and Packet-switched traffic under the scene of BNG separation, PCRF can also send the QCI information of carrying by the S2a interfaces between mobile packet data gateway and TWAG to TWAG, so that TWAG carries out DSCP marks according to the QCI information of carrying to the packet-switched traffic.

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

In specific implementation process, after step S29, BPCF is triggered to BNG Send gateway control session management（Including setting up reply, modification etc.）Message, the message include DSCP marking conventions or DSCP mapping indicate, and packet-switched traffic description information（For example with mobile terminal and EPDG address is five-tuple address information）Deng to trigger BNG activation to the data flow of mobile terminal progress packet-switched access according to mapping instruction progress DSCP value marks etc..

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

In embodiments of the present invention, the PCRF On due to the triggering of some conditions, such as, detect change, the PCRF of the remaining amount of change, the change of network congestion condition, user of subscription data On local policy or because detect some special data flows etc., then can update and be issued to DSCP marking conventions, then the DSCP that the BPCF is received is labeled as DSCP obtain in real time, newest Marking convention, so as to it is more flexible, exactly issue marking convention.Namely the BPCF can send DSCP marking conventions to BNG and/or TWAG in real time so that BNG and/ Or TWAG activation carries out DSCP values to the related data flow of mobile terminal and marked.In addition, the DSCP marking conventions can also be included in PCC rules or QoS rules, in BNG Receive after the rule, the mark in PCC rules or QoS rules is indicated, the specific DSCP being pre-configured with BNG is activated with the granularity of every terminal Mapping table etc. is marked, the concrete mode of mark includes carrying out each IP packets one by one DSCP mappings, the DSCP values according to QCI value flag data streams, keeps DSCP It is constant or the DSCP values of corresponding data stream are marked as to indicated value etc..

In embodiments of the present invention, when policy entity is other policy entities comprising the BPCF functions, the BPCF will can be included Other policy entities of function substitute the above-mentioned BPCF, realize that BNG or TWAG, to operations such as the DSCP marks processing of data flow, will not be repeated here by above-mentioned steps.

It should be noted that after in fixed network equipment access network, the BPCF or other policy entities comprising the BPCF functions DSCP marking conventions corresponding with the fixed network device data stream are directly generated, without using the PCRF, will not be included in other words in the PCC rules or QoS rules that PCRF issues, and should DSCP marking conventions are sent to BNG, so that the fixed network node BNG is according to the DSCP marking conventions, the data flow to the fixed network equipment carries out DSCP marks.

Further, BNG or TWAG are needed in due course to DSCP Marking convention is deactivated or invalid.Such as, in Fig. 2, when all PDN connections of mobile terminal accessing packet switched data disconnect, PCRF will be triggered to BPCF Gateway control session end is sent, while can also issue the QoS rules after updating, QoS rules are now used to notify fixed network releasing network resource etc., and BPCF Receive after the gateway control session end, terminate with the gateway control session of the PCRF, and sent to BNG or TWAG and deactivate DSCP marking conventions, then cause BNG or TWAG carries out deactivating DSCP map tags processing etc. for the packet-switched traffic of mobile terminal.Now, BNG local unloading data diffluences also all to terminal have activated DSCP mark functions.

Embodiment three：
