Below by way of specific example, the essence of the technical solution for embodiment that the present invention is furture elucidated.
When user access network, business chain policy control functions issuing service policy message can be driven to give flow point class
Device.
Fig. 2 is the flow chart of the business chain policy optimization method of the embodiment of the present invention two, as shown in Fig. 2, business chain strategy
Control function entity is responsible to define and updates business chain strategy, and gives business chain policy distribution to flow classifier (TC).Flow point class
Device is responsible for coming out traffic differentiation according to business chain strategy, and according to business chain strategy, flow is directed through to different flows
Processing capacity entity (VAS, Value-added logistics service) passes through different business chains, has to upper
Capable and downlink traffic carries out the ability of depth Packet analyzing and flow point class.In business chain policy message or business chain policy update message
Business chain Rule Information is carried, this Rule Information may include customer flow identification information, business feature information, network state letter
Breath, APN information, downlink DPI whether offload and business chain identification information.The same business chain policy message or business chain
Policy update then shows to guide its flow by certain for certain business under certain network state or APN information Mr. Yu user
A business chain, while illustrating whether downlink DPI is not suitable for.Wherein, customer flow identification information can be user code number, can also be with
It is identified with source IP address；For business feature information there are two types of expression way, one kind is the address URL or destination IP list or other streams
Measure feature information, the characteristic informations such as the address URL or purpose IP address are business relevant with certain class or some service provider
Feature can help to identify outflow by these features；One kind is service identification, i.e., a kind of code name (such as number), this generation
Number connotative meaning can be some business or some business of some service provider, the corresponding feature of this service identification,
It is stored in the equipment such as flow classifier or gateway, and the configuration and update of feature set can be carried out.Network state information includes
The information such as network congestion degree, access network type.Downlink DPI whether offload, if so, showing that downlink traffic does not need
DPI；If it is not, showing that downlink traffic needs DPI to handle, discharge characteristic is further identified.Business chain identification information is a kind of
Mark, can represent the flow rate capacity entity set to get up according to certain sequential organization, can represent for uplink traffic
Uplink service chain is identified and is identified for the downlink business chain of downlink traffic, is respectively intended to guidance uplink and downlink flow.
Policy update message in Fig. 2 can be a new more new strategy as policy message；It also can be a shape
State information, this state change information can be network state information, temporal information, customer position information, and flow classifier receives shape
After state change information, business chain mark is updated, prior flow classifier obtains relevant all industry from policy control functions
Business chain strategy.Network state information can be network congestion information, network insertion type information.
In Fig. 2 by taking DPI is a part of TC as an example, the relationship of TC and DPI can be conjunction and sets, and can also call DPI's with TC
Relationship.In addition, TDF has the ability of deep-packet detection (DPI) in 3GPP standard, TC can call the ability of TDF, can also be with TC
It is a module in TDF, can also be that TDF is a module of TC；PCEF function is defined in 3GPP standard, has reception
The ability of PCRF strategy, TC can also be realized based on the function of extension PCEF.
It may include one or more business chain information in business chain policy message or business chain policy update message.
In business function chain, TC sets up separately with mobile packet gateway equipment (GW), can also close and set.It will illustrate respectively below
Set up and close the scene set separately.
TC and GW set up scene separately, i.e., when TC and GW equipment separates, scheme is as shown in Fig. 3 a, 3b, when user is from gateway
When obtaining IP address, gateway can be by the IP address informing business chain control function (flow i.e. on path 11) of user, business chain
TC is given in control function meeting issuing service chain policy message (carrying business chain Rule Information), since TC can not obtain user code
Number, therefore the customer flow identification information in business chain policy message needs to identify using source IP address.UE initiates data traffic
When, TC (flow i.e. on path 4) first can be directed to, TC is according to business chain strategy for the flow on path 1 by GW
The rule for including in message carries out flow point class, and convection current is marked, and marks the business chain of uplink traffic to identify, for path 3
On flow will be identified according to business chain, flow through the VAS using whereabouts, enter internet from egress router, i.e., on path 9
Flow.
For the flow in downlink path 10, it can be first directed to TC, i.e. flow on path 4, it will in the following several ways:
Downlink traffic does not need DPI analysis, and directly downlink traffic is marked, label downlink business chain mark.It is a kind of
Situation is that the characteristic of downlink traffic can be analyzed by uplink traffic, this is the cooperation mould between operator and service provider
Formula (i.e. the feature, such as URL, IP list etc. of service provider's informing operator's flow) scene；Another situation is that due to fortune
The business chain strategy for seeking quotient does not need still to carry out a part of analysis to flow, this belongs between operator and service provider
Non- modality for co-operation.
Downlink traffic needs DPI to analyze, then needs further depth Packet analyzing, to match the business feature of flow, and presses
According to business chain rule, corresponding downlink traffic business chain is selected to identify, i.e. label downlink traffic business chain mark.This situation is general
Non- modality for co-operation between operator and service provider, operator can not judge the characteristic of flow by uplink traffic, therefore
It needs to carry out depth Packet analyzing to the content of downlink traffic.
It for the flow that TC has been marked, is come out from path 3, is defined through the VAS that pass through according to business chain, then
It is directed into GW.
For the flow of business chain mark has been marked, uplink and downlink flow can complete VAS treated route switching
Remove label in equipment.
TC and GW closes the scene set, i.e., when the conjunction of TC and GW equipment is set, is divided into the implementation of TC and two TC.It is right
In the implementation of a TC, process is similar with process flow shown in Fig. 3.As shown in figure 4, TC is from business chain policy control
Function obtains business chain policing rule message, and uplink traffic is by GW, TC and the VAS that should be gone, subsequently into internet；Such as figure
Shown in 5, downlink traffic arrives first TC, then by the VAS that should be gone, returns TC and GW, is eventually returned to user equipment.Difference
It is since TC and GW conjunction is set, TC can obtain the information such as user code number, IP address from GW, when formulating business chain strategy,
User code number can be used and be used as customer flow identification information.When carrying out identity user flow using IP address, the function of TC
It can be identical as the TC for setting up scene separately；When carrying out identity user using user code number, there can be interface to obtain user before TC and GW
The corresponding relationship of code number and IP address.TC is also equipped with the function of removing business chain mark.
In above-described embodiment, for downlink traffic, flow can repeatedly pass through gateway, bring to gateway additional
Therefore expense closes the scene set for TC and GW, two TC can be used to advanced optimize.
It is two as scenes of TC1 and TC2 for TC, the TC and GW that is functionally similar to of TC1 closes the function for setting TC in scene
Energy.TC1 and business chain policy control functions entity interaction obtain business chain policy rule information (as shown in Figure 1), carry out uplink
And the flow point class of downlink traffic, TC2 are only downlink business chain mark to be obtained from uplink traffic, and store record, work as downlink
When flow flows through TC2, convection current is subjected to business chain logo.Specifically, as shown in Figure 6,7, when TC1 do not need to downlink traffic into
When row DPI, TC1 has judged uplink traffic should be by which business chain, and downlink traffic should by the identification of uplink traffic
By which business chain, when TC1 flows out TC1 for uplink traffic, the business chain mark of uplink traffic is not only identified, it also will mark
Remember the business chain logo of downlink traffic.After uplink traffic flows through VAS, TC2 is arrived, storage is recorded the industry of downlink traffic by TC2
Business chain logo, and remove the business chain flag information of upstream.When downlink traffic flow is through TC2, by convection current tagged traffic chain mark
Will is flowed with guidance and passes through corresponding VAS, is then return to TC1.TC1 can convection current indicate.For this kind of flow, than single TC
And gateway conjunction sets scene, reduces the expense to gateway.
It is two as scenes of TC1 and TC2 for TC, TC1 and TC2 can be real with business chain policy control functions respectively
Body interacts, and obtains business chain policy rule information respectively.At this point, the business chain of the available uplink traffic of TC1 identifies,
The business chain of the available downlink traffic of TC2 identifies.
As shown in Fig. 6,8, when TC1 needs to carry out DPI to downstream, i.e., by the analysis of uplink traffic, it can not determine
The characteristic of downlink traffic, TC1 will carry out DPI to downlink traffic, to obtain business feature, and then business chain be added for downlink traffic
Mark passes through corresponding VAS from direct traffic, is then return to TC1, TC1 removes the business chain logo of downlink traffic.
Network address translater (NAT, Network Address Translation) is used as a kind of VAS, to Business Stream
Flowing through path will be influenced, and as shown in Figures 9 and 10, be illustrated so that TC and GW set up scene separately as an example.Certainly, NAT is as a kind of
The mode of VAS, which is also applied for closing, sets scene.If what user terminal obtained is internal address, will need by nat feature, if
What user terminal obtained is public network IP, will need not move through NAT processing.What it is for user terminal acquisition is public network IP address (example
Such as business chain 1), downlink traffic will be directed into TC and carry out flow point class before entering VAS, identical as usual situation.But work as
User terminal obtain be internal address when (such as business chain 2), for uplink traffic as usual situation, need by
Then TC said VAS1 and VAS2.For downlink traffic, before entering VAS and TC, first direct traffic is needed to pass through
VAS2 (NAT) distributes corresponding business chain logo by TC then using TC, passes through VAS1 with direct traffic, then arrives again
