Embodiment one
Present embodiment provides a kind of dispatch control method of customer flow:
As shown in Figure 2, in the present embodiment, the dispatch control method of customer flow can comprise:
S201, access node generate the Access Node Control Protocol message, and said Access Node Control Protocol message carries indication information, with the indication network access server customer flow is dispatched.
S202, access node send said Access Node Control Protocol message to network access server.
In the enforcement, the ANCP message carries indication information among the S201, and with indication NAS customer flow being dispatched to have multiple mode, and for example: the newly-generated ANCP message of AN, this ANCP message are exclusively used in indication NAS customer flow is dispatched; Perhaps, the newly-increased indication information of indicating NAS that customer flow is dispatched of being used in existing ANCP message (for example line configuring is receiveed the response, Topology Discovery message etc.); Perhaps,, in these fields, carry the indication information that indication NAS dispatches customer flow, such as some field in the expansion ANCP heading through expanding some field in the existing ANCP message.
Fig. 3 is the sketch map of ANCP heading, and the field that can comprise in the ANCP message has been shown among the figure to be had: version number (Vers), sub-version number (Sub), type of message (Message Type), response (Result) and code word (Code) field.Be example with the reply field in the expansion ANCP heading below, the method that AN dispatches customer flow through ANCP message indication NAS is described.Certainly, expand reply field here and be merely an example, can expand other field in the ANCP message in the enforcement, or adopt other can realize the method for customer flow being dispatched through ANCP message indication NAS.
In existing ANCP agreement, following to the definition of reply field:
To ANCP message sender:
NoSuccessAck (successfully not responding): Result=1
AckAll (responding all): Result=2
To ANCP message recipient:
Success (success): Result=3
Failure (failure): Result=4
In this example, can expand reply field, as: be the newly-increased type of reply field; Be used to indicate NAS that customer flow is dispatched,, can claim that the type is " line configuring application " for describing conveniently; And Result=8 under hypothesis the type, then definable is following:
LineConfigApply (line configuring application) Result=8 (using when AN sends)
In the enforcement,, just can dispatch customer flow through access node Control Network access server as long as access node carries such indication in the Access Node Control Protocol message that network access server sends.
Certainly, optional, AN can generate the node control protocol massages that indication NAS dispatches customer flow, and send to NAS in needs.
For example: when AN does not support to handle the subscriber's line configuration messages from NAS (this ability at the ANCP capability negotiation time confirm), AN can generate the ANCP message, and indication NAS dispatches customer flow.Again for example: when AN did not support customer flow dispatched, this moment, AN also can generate the ANCP message, and indication NAS dispatches customer flow.Under above-mentioned two kinds of situation, AN is failure to the result of customer flow scheduling.
Certainly, except above-mentioned two kinds of situation, in some other scene, AN also can generate the node control protocol massages that indication NAS dispatches customer flow, and sends to NAS.For example: AN receives the subscriber's line configuration messages that NAS issues, and also possesses the ability of handling this message, still, and for fear of NA
Link congestion between S and AN, AN can generate the ANCP message, and indication NAS dispatches customer flow.Again for example: after AN receives certain user's that NAS issues QOS strategy; Link bandwidth between AN and user changes; Make link bandwidth between AN and user less than user's in the QOS strategy total bandwidth, this moment, AN can generate the ANCP message, and indication NAS dispatches customer flow.
Link bandwidth with between AN and user changes, makes that the link bandwidth between AN and user is an example less than user's in the QOS strategy total bandwidth:
In this example, this ANCP message can be a Topology Discovery message, and then above-mentioned S201 practical implementation can be following: access node generates Topology Discovery message, and said Topology Discovery message indication network access server is dispatched customer flow.
Present embodiment can be dispatched customer flow through access node Control Network access server, creates conditions for realizing that network access server is dispatched customer flow, and network access server is dispatched customer flow becomes possibility.
Embodiment two
Present embodiment provides a kind of dispatch control method of customer flow, and is as shown in Figure 4, and handling process can be following:
S401, NAS receive the ANCP message that AN sends, and said ANCP message carries indication information, and indication NAS dispatches customer flow.
S402, NAS dispatch customer flow according to the indication of said ANCP message.
Similar with the description among the last embodiment, in the present embodiment, the ANCP message from AN that NAS receives can be a newly-generated message of AN, and this message is exclusively used in indication NAS customer flow is dispatched; Also can be the multiplexing existing ANCP message of AN (for example line configuring is receiveed the response, Topology Discovery message etc.), in this message, increase newly and be used to the sign of indicating NAS that customer flow is dispatched; Or, be AN multiplexing existing ANCP message, some field in this ANCP message is expanded, be used to indicate NAS that customer flow is dispatched.
Can know that by flow process shown in Figure 4 NAS is after receiving the ANCP message that AN sends, according to said A
The indication of NCP message is dispatched customer flow, realizes that with this NAS dispatches customer flow.
Still change, make that with the link bandwidth between AN and user the link bandwidth between AN and user is an example less than user's in the QOS strategy total bandwidth:
Network access server will receive the ANCP message that access node is sent, and this ANCP message can be a Topology Discovery message, and said Topology Discovery message indication network access server is dispatched customer flow;
Then in this example, above-mentioned S402 can be embodied as: NAS revises user's in the quality of service policy total bandwidth according to the indication of said Topology Discovery message.For example, NAS can compare user's in link bandwidth between current AN and user and the QOS strategy in the said Topology Discovery message total bandwidth; According to comparative result, when the link bandwidth between AN and user less than the QOS strategy in during user's total bandwidth, revise user's in the QOS strategy total bandwidth.
Certainly, in the enforcement, NAS also can limit up and down linear flow rate total bandwidth, perhaps the different business of dispatched users etc. in proportion.As: NAS can adjust this user's downlink traffic, to avoid the link congestion on the AN.
In the present embodiment, NAS according to the indication of said ANCP message, dispatches customer flow after receiving the ANCP message that AN sends, and realizes that with this NAS dispatches customer flow.
Embodiment three
By the description of the foregoing description, can know that in optional embodiment, AN can generate the node control protocol massages that carries indication information in needs, NAS dispatches customer flow with indication, and sends to NAS.For example, AN is to the result of customer flow scheduling during for failure.At this moment, can dispatch user's flow by AN earlier, when AN to the result of customer flow scheduling during for failure, the node control protocol massages that regeneration indication NAS dispatches customer flow, and send to NAS.
As shown in Figure 5, the instantiation that customer flow is dispatched can comprise:
S501, network access server send the subscriber's line configuration messages to access node.
S502, access node are dispatched customer flow according to said subscriber's line configuration messages after receiving the subscriber's line configuration messages.
S503, at access node to the result of customer flow scheduling during for failure, access node generates the ANCP message, this ANCP message indication network access server is dispatched customer flow, in the enforcement, this ANCP message can be that line configuring is receiveed the response.
S504, access node send aforementioned line configuring to network access server receives the response.
The indication that S505, network access server are receiveed the response according to said line configuring is dispatched customer flow.
In the enforcement, can also introduce customer flow scheduling result feedback mechanism, make NAS can know the result that AN dispatches customer flow.For example, when NAS sends the subscriber's line configuration messages to AN, can in this message, carry indication information, AN returns the result that customer flow is dispatched to NAS with indication.Like this, when AN when NAS transmitting line configuration is receiveed the response, can also be by the indication of said subscriber's line configuration messages, receive the response through this line configuring and to return the result that customer flow is dispatched to NAS.
Customer flow is dispatched similar with embodiment one, two said AN through ANCP message indication NAS; Subscriber's line configuration messages indication AN returns the result that customer flow is dispatched to NAS also can have multiple mode, for example in the subscriber's line configuration messages, increases newly to be used to indicate AN to return the result's that customer flow is dispatched sign to NAS; Perhaps, through some field in the extending user line configuring message ANCP message, indication AN returns the result that customer flow is dispatched to NAS, such as some field in the expansion ANCP heading.
Be that example describes still with the reply field in the expansion ANCP heading here; Certainly can expand other field in the ANCP message in implementing, or adopt other can realize that subscriber's line configuration messages indication AN returns the result's that customer flow is dispatched method to NAS.
In this example; Consideration is expanded reply field, for example: for the newly-increased type of reply field, be used to indicate AN to return the result that customer flow is dispatched to NAS; For describing conveniently; Can claim that the type is " a line configuring feedback ", and Result=7 under hypothesis the type, then definable is following:
LineConfigAck (line configuring feedback) Result=7 (using when NAS sends)
In the present embodiment; AN is to the result that customer flow is dispatched of NAS feedback; Can make NAS clearly need its former customer flow scheduling that customer flow is dispatched to fail because of AN; Thereby further perfect under the situation that AN and NAS all can dispatch customer flow, the coordination system between the two.
Introduce a concrete application example below; How to realize that with explanation NAS dispatches customer flow; In this example,, realize that AN indication NAS dispatches customer flow and NAS indication AN returns the result that AN dispatches customer flow to it through reply field in the expansion ANCP message:
As shown in Figure 6, in this example, when the POLICY server issues QOS when strategy of certain user to NAS; NAS issues this QOS strategy through the ANCP agreement to AN; And when issuing, be 7 at the mid-Result of ANCP message, promptly aforementioned " line configuring feedback "; Require AN to return QOS application of policies result, the result who promptly customer flow is dispatched.After AN receives this ANCP message,, send back message using (being that line configuring is receiveed the response) and give NAS according to the result that customer flow is dispatched.If AN is failure to the scheduling result of customer flow, then the Result field in the back message using is changed to 8, promptly aforementioned " line configuring application ".
Lift a concrete application example below again, explain how the previous embodiment method realizes that NAS dispatches customer flow, in this example,, realize that AN indication NAS dispatches customer flow also through reply field in the expansion ANCP message:
As shown in Figure 7, in this example, AN is to the Topology Discovery message of NAS report of user, and indication NAS dispatches customer flow, and the Result field of then putting the ANCP message is changed to 8, promptly aforementioned " line configuring application ".After NAS receives this Topology Discovery message; With the link bandwidth between current AN and user in this Topology Discovery message; And a preceding user bandwidth information (being user's in the QOS strategy total bandwidth) of on NAS, preserving compares; When finding that link bandwidth between AN and user diminishes and during less than the user's total bandwidth in the QOS strategy, then NAS revises user's in the QOS strategy total bandwidth, and to the adjusted QOS strategy of POLICY server forwards.
