The Diameter closing equity end connects.And in queue, those also do not terminate from equity
Receive the pending message of response message, be reassigned to other available replacement equity ends to enter
Row fault transfer processing.
Scheme 2: close use before Diameter connects with reality receiving DPR message
One intervalometer.It is to say, when Diameter network element sends DPR message to its equity end
Time, it should be closed before Diameter connects in reality and start an intervalometer, continue simultaneously
The ongoing request of continuous process.On the other hand, when equity termination receives DPR message,
It should also be as closing Diameter in reality and connects and stop distributing new request to equity end
Start an intervalometer before message, wait the sound for ongoing request message simultaneously
Answering message, connecting until just closing Diameter during timer expiry.
Summary of the invention

But, it will be understood by those skilled in the art that the name of above-mentioned two pairs of message is simply shown
Example, it is not intended that the restriction to its protection domain, their protection domain is by following institute
Their function described in detail limits.
Fig. 1 shows the method 100 for carrying out Diameter connection management according to the present invention
Flow chart.
As shown in fig. 1, at the step 110 of method 100, a Diameter network element P1
DCR message is sent to the 2nd Diameter network element P2.
DCR message is used for so that the 2nd Diameter network element P2 stops by a Diameter
Diameter between network element P1 and the 2nd Diameter network element P2 connects to a Diameter
Network element P1 sends new service request, keeps simultaneously and does not turns off Diameter therebetween
Connect.
Next, on the one hand, in a Diameter network element P1 side, in step 120,
Oneth Diameter network element P1 continues with the pending of the 2nd Diameter network element P2 transmission
Service request.Here, pending service request refers to that the 2nd Diameter network element P2 is receiving
To DCR message forward direction the oneth Diameter network element P1 send, the most do not obtain first
The service request of the response of Diameter network element P1.
In step 130, a Diameter network element P1 sends out to the 2nd Diameter network element P2
Send the response message for pending service request.
On the other hand, in the 2nd Diameter network element P2 side, in step 140, second
Diameter network element P2 in response to received from a Diameter network element P1's
DCR message, stops by a Diameter network element P1 and the 2nd Diameter network element P2
Between Diameter connect and send new service request to a Diameter network element P1,
Keep simultaneously and do not turn off this Diameter and connect.As an alternative, the 2nd Diameter network element
Other available Diameter network elements that new service request can also be distributed in network by P2
To complete its business.
Additionally, method 100 can also include step 150, wherein the 2nd Diameter network element
P2 is receiving after the DCR message of a Diameter network element P1, to first
Diameter network element P1 returns DCA message using as response.
In FIG, after step 150 is shown in step 110, step 120 and
Before 140.It will be appreciated by those skilled in the art that the invention is not limited in this, step
After rapid 150 can also be in step 120 and 140.Or, in some cases, also
Can need not perform step 150, i.e. need not return DCA message, such as, when
In standard or system prespecified time.
It can be seen that different from DPR message, a Diameter network element P1 and second
Actual switch-off is not therebetween after the mutual DCR message for Diameter network element P2
Diameter connects, and only stops new service interaction therebetween.
Furthermore, it is to be understood that the effect of DCR message is only off two Diameter network elements
Between new service interaction, the most still can be used for connecting monitoring and management alternately
DWR/DPR message etc..
It follows that deposit between a Diameter network element P1 and the 2nd Diameter network element P2
At two kinds of service conditions.
In one case, a Diameter network element P1 and the 2nd Diameter network element P2
Need to proceed service interaction.Such as, generally there is a Diameter net in this situation
When unit P1 needs to perform additional operation, the such as the oneth Diameter network element P1 to take
There is fractional hardware fault in business upgrading, system configuration change and a Diameter network element P1
When needing to replace.
To this end, method 100 farther includes step 160, a wherein Diameter network element
P1, after having processed all pending service request, performs additional operation (in Fig. 1
Shown in dotted line frame).
Step 170, after this additional operation completes, a Diameter network element P1 to
2nd Diameter network element P2 sends ECR message (as shown in dotted line frame in Fig. 1).
This ECR message is used for so that the 2nd Diameter network element P2 can be again through first
Diameter between Diameter network element P1 and the 2nd Diameter network element P2 connects to the
One Diameter network element P1 sends new service request.
Additionally, similar with DCA message, after receiving ECR message, the 2nd Diameter
Network element P2 can also send ECA message as response message to a Diameter network element P1.
Receive from a Diameter network element P1's at the 2nd Diameter network element P2
During ECA message, the 2nd Diameter network element P2 can be by a Diameter network element P1 mark
It is designated as the Diameter network element that can use, such that it is able to connected to first by this Diameter
The service request that Diameter network element P1 distribution is new.
In another case, Diameter network element P1 and a 2nd Diameter network element
Further service interaction is no longer carried out between P2.It is to say, disconnection that will be more graceful
Diameter between one Diameter network element P1 and the 2nd Diameter network element P2 connect and
Do not produce the problem in prior art.
In this case, a Diameter network element P1 is processing all pending business
After request, send DPR message to disconnect this Diameter to the 2nd Diameter network element P2
Connect (not shown).
In fig. 1 it is shown that the connection management between two Diameter network element P1 and P2
Method.It will be understood by those skilled in the art that Diameter network element be P2P communication in right
At end, it is that P2P connects that the Diameter between two Diameter network elements connects.The opposing party
Face, it is also possible to the Diameter network element of initial request messages is referred to as Diameter client,
The Diameter network element receiving and processing request message is referred to as Diameter server.But,
It will be understood by those skilled in the art that in Diameter, which node is client,
Which node is server difference the most in logic, at Diameter layer not
Difference in realization.
In one implementation, the new Diameter message proposed in the present invention can be determined as follows
Justice:
The above-mentioned introducing for the new commands/messages of Diameter connection management will affect
Existing Diameter equity end state machine defined in RFC3588, with the addition of expression and initiates
I-Blocked state and expression receiving terminal (receiving DCR) that end (transmission DCR) enters
The R-Blocked state entered.Table 1 below reflects the state machine of new extension.

Entire flow figure under two kinds of concrete application scenarios.Wherein, in fig. 2 it is shown that work as
Diameter server is scheduled for maintenance window to stop from its Diameter equity end
The business of (Diameter client), and when the tending operation is completed, by Diameter
Equity end notifies that it can be used to continue the call flow 200 under the application scenarios of call treatment.
Each step of Fig. 2 is briefly described as follows:
Step 210:Diameter server and Diameter client are disappeared by CER/CEA
Breath is set up Diameter and is connected.
Step 220:Diameter client to Diameter server send service request with
In calling procedure；Diameter server processes the service request from Diameter client
And return response message.
Step 230:Diameter server is scheduled for maintenance window and to Diameter
Client sends DCR message, to stop the service request from Diameter client, but
It is to maintain and does not turns off Diameter and connect.
Step 240: after receiving DCR message, Diameter client is to Diameter
Server returns DCA message to respond this DCR message.
Step 250: after receiving DCR message, Diameter client stops sending
New service request is to Diameter server, but is to wait for the sound to pending request message
Should, and perform failover process new service request to be distributed to what other can use
Diameter equity end.
Step 260:Diameter server continue with pending service request and to
Diameter client returns response message.
Step 270:Diameter server performs its scheduled maintenance operation.
Step 280: when maintenance completes and can be used for continuing service, Diameter server
Send ECR message existing with notice this server of Diameter client to Diameter client
Available；After receiving this ECR message, Diameter client takes to Diameter
Business device sends ECA message to respond.
Step 290: after receiving this ECR message, Diameter client continue to
Diameter server distributes and sends service request, and performs with Diameter server
Business Processing.
In fig. 3 it is shown that when Diameter server needs to close itself and Diameter visitor
Call flow 300 under the application scenarios that Diameter between the end of family connects.
Step 310-360 in Fig. 3 is essentially identical with step 210-260 in Fig. 2.
Flow process 300 is with the difference of flow process 200, in step 370, works as Diameter
After the complete all of pending service request of server process, send to Diameter client
DPR message connects with the Diameter disconnected therebetween.
In step 380: when Diameter client receives from Diameter server
During DPR message, send DPA message to respond to Diameter server.

Without service being produced the ability of impact.
Generally speaking, the present invention is by introducing Diameter connection management free of discontinuities so that energy
Enough by temporarily stoping the service request in Diameter connection to lose ongoing
Request, keeps Diameter to connect survival simultaneously.Such as, aforementioned capabilities is for following application
Situation has the significant advantage that
(1) equity end service upgrade
Service upgrade is generally carried out in maintenance window, say, that when by Diameter net
When unit is upgraded to a new software version to obtain new service, it generally should ask resistance
Only to all service request of this Diameter network element, the most temporarily interrupt this Diameter even
Connect a kind of simple mechanisms being to stop the service request to this Diameter network element.
(2) system configuration change
Sometimes for carrying out some system configuration changes to support some new functions, this may
Need to restart Diameter network element so that system change comes into force.
(3) fractional hardware fault and replacement
In the case of fractional hardware fault, such as at hard disk failure or Ethernet interface/card
During etc. fault.This fractional hardware fault can't cause completely Diameter network element failure and
It is generally of the nextport hardware component NextPort of redundancy to continue with all business, needs still exist for replacing
Change the hardware components of fault to avoid dual hardware fault to cause the event completely of Diameter network element
Barrier.In order to replace the nextport hardware component NextPort of fault, it should firstly the need of closing Diameter network element.
So that the impact on service minimizes when Diameter network element is closed, it is desirable to graceful
Close Diameter network element.That is, it is desirable to stop from ext nal network element to this Diameter
The all new business of network element, make simultaneously this Diameter network element continued all
The call treatment carried out.
In the case of Diameter equity end supports DCR/DCA, Diameter equity end/
Client should stop to this Diameter network element/server only distributing new request message
Allow response message.Therefore on the one hand, server gets sky from Diameter storehouse
Know there is no new ongoing request, on the other hand, operator during Diameter queue
Can reality close check before Diameter network element application layer measured value/daily record (generally its
Application layer measured value is utilized to indicate the all-calls received in a time interval, if
The instruction of this measured value has 0 calling in a time interval, then this expression does not has new exhaling
Cry entrance).
Further, introduce above-mentioned new message and can't cause backward compatibility issues.The most just
It is to say, in the case of Diameter equity end does not support DCR message, Diameter equity
End should return has DIAMETER_COMMAND UNSUPPORTED's
Protocol Error message, thus Diameter network element knows that its equity end does not support this merit
Can, state is still I/R-OPEN as normal condition, say, that its Diameter pair
Continue to send service request to this Diameter network element at end.
For prior art, the present invention provides the notable advantage that in the following areas
1. the present invention is very simple, from providing Diameter connection management free of discontinuities, and
And realize closing Diameter connection grazioso, and implement relatively easy, it is possible to save and open
Send out cost.
2. utilize the present invention to provide between the ends such as Diameter connection management realization free of discontinuities
The ability that Diameter connects, it is possible to be greatly enhanced QoS to support 0 Call failure.
3. the invention enables Diameter network element can detect in time its equity end state and
Fault transfer and fault recovery is carried out in time based on its equity end state.
4. present invention can also apply to when Diameter network element is the busiest and just can not process
Premature beats when the business carried out.
5. utilize the present invention, when carrying out distribution of services and controlling, it is not necessary to actual switch-off is transmitted
Connect to come and stop when Diameter network element is temporarily unavailable distributing industry to this Diameter network element
Business, thus when Diameter network element recovers, include that this transmission connects without re-establishing
Diameter connect.This has prominent advantage for following application scenarios:
(1) when Diameter network element has some internal errors, such as internal process/line
Journey fault, needs to take a moment and automatically repairs, and the time period recovered in internal fault
Period, Diameter network element wishes to stop from outside Diameter equity end to this Diameter
The business of network element.Therefore this ability can be used to notify Diameter equity end the most not
Can be used to stop Diameter equity end to send business without disconnected to this Diameter network element
Open this Diameter to connect.
(2) at Diameter network element, there are some shortages of resources, such as memorizer budget or line
When the internal queues of journey or process is used up, Diameter network element can use this ability to stop
New to wait that internal resource discharges processing from the business of outside Diameter equity end
Request.
(3) Proxy Agent due to some temporary fault (network problem etc.) can not be right with it
Communicating Deng end Diameter server, Proxy Agent can ask its Diameter equity end
Client stops sending business to Diameter Proxy Agent and need not being disconnected to this equity end
The connection of client.
