Alternatively, the diameter of the first predetermined quantity in the diameter signaling link of the above-mentioned predetermined quantity of deexcitation Signaling link configure between the first virtual machine in dra equipment and diameter node, the first virtual machine with It is also configured with the diameter signaling link of the second predetermined quantity of activation, Fig. 9 is according to this between diameter node The structured flowchart of flexible module 24 is deactivated in the adjusting apparatus of diameter signaling link of inventive embodiments, as shown in figure 9, This deactivates flexible module 24 and includes processing unit 92, deactivates flexible module 24 to this below and illustrates.
Processing unit 92, for closing above-mentioned first virtual machine, and the diameter signaling by above-mentioned second predetermined quantity Between the second virtual machine and diameter node that link migrates to dra equipment so that the second virtual machine with There is the diameter signaling link of the second predetermined quantity of activation between diameter node.
Figure 10 is the structured flowchart of diameter route agent dra according to embodiments of the present invention, as shown in Figure 10, This dra 102 includes the adjusting apparatus 104 of the diameter signaling link of any of the above-described.
By above-described embodiment, can with present in effectively solving correlation technique, in dra network element, operator according to Traffic summit traffic and other factors, have planned the more signaling link of number, but because signaling link cannot enter Row elastic telescopic, causes a large amount of wastes of the signaling link resource during normal traffic or during low traffic, and seriously The elastic telescopic of impact virtual machine, makes the problem that the environmental protection ability that virtualization brings lost efficacy to a certain extent.
For the problems referred to above, in the embodiment of the present invention, additionally provide a kind of realization side of diameter signaling link elastic shrinkage Method, illustrates below for the method.
Operator configures dra to the signaling link of other diameter adjacent nodes (peer).Stretch for supporting elasticity The adjacent node of contracting, configures the maximum signaling link way (such as 32) of this node, minimum signaling link way (such as 2 Bar).And configure those links and do not carry out elastic telescopic, which is used for elastic telescopic.For can elastic telescopic signaling link Road, the elastic telescopic priority of every signaling link of setting.And arrange which signaling link electricity initially sets up.
Need when setting up diameter signaling link to carry out capability negotiation (capabilities exchange request (capabilities Exchange-request, referred to as cer) and/capabilities exchange response (capabilities exchange-answer, referred to as For cea)), in capability negotiation message, increase signaling link elastic telescopic attribute (i.e. " elastic telescopic type " and " elastic telescopic priority ") negotiation.Elastic telescopic class is: " scale fix ", " scale enable ".Elasticity is stretched Contracting class is that the link of " scale fix " does not carry out elastic telescopic, does not need to arrange elastic telescopic priority；Elastic telescopic class Property can carry out elastic telescopic for the link of " scale enable ", elastic telescopic priority need to be set during negotiation；
Signaling link " scale in ": when the total link load of certain peer declines, need to close some or all of signaling During link, according to the elastic telescopic priority of signaling link, the minimum signaling link of elastic telescopic priority is selected to initiate disconnected Chain, that is, send dpr (disconnect-peer-request) message.By arranging " disconnect-cause in dpr message The enumerated value of avp " is indicated chain rupture reason for " scale_in (3) ".For the chain being caused due to elastic shrinkage Situation is closed on road, and both sides' network element can not produce high severity alarm, does not also rebuild link immediately.
Signaling link " scale out ": when the total link load of certain peer rises, when needing to increase signaling link, press According to the elastic telescopic priority of signaling link, the link of highest priority is selected to initiate the reconstruction of signaling link.
Figure 11 is that the signaling link configuration schematic diagram of dra according to embodiments of the present invention and adjacent peer (does not support letter Making the double influence of link elastic telescopic) the signaling link quantity of dra and adjacent peer is to calculate according to maximum traffic , when 4g customer volume is very big, if carry out full configuration put, some adjacent peer are maximum to can configure 32 signaling links Road.When telephone traffic relatively low (such as the load of every link is a%), the utilization rate of signaling link bandwidth is very low, makes Become the wasting of resources；Meanwhile, this dra needs to apply for more vm virtual machine it is impossible to continue scale in.
Figure 12 is that the scale in schematic diagram of the signaling link of dra according to embodiments of the present invention and adjacent peer (is supported The double advantage of signaling link elastic telescopic).For the situation of Figure 10, if supporting the elastic telescopic of signaling link, Carry out elastic shrinkage (scale in), then each peer only needs during telephone traffic very low (such as the load of every link is a%) 2 signaling links are wanted to enter line activating (such as the load of every link is 16xa%)；Meanwhile, this dra also only needs Apply for less vm virtual machine.
Figure 13 is that the signaling link configuration schematic diagram of dra according to embodiments of the present invention pcrf adjacent with a group (is not propped up Hold the elastic telescopic of signaling link) it is assumed that dra is attached with 16 pcrf, the function of each pcrf is complete Equivalence, each adjacent pcrf configures 32 signaling links.Telephone traffic extremely low (such as the load of every link is b%) When, signaling link resource, or even many pcrf node resources all cause to waste；Meanwhile, this dra is also required to apply for More vm virtual machine.
Figure 14 is the scale in schematic diagram of dra according to embodiments of the present invention and adjacent pcrf group, for Figure 13 Situation, if support signaling link elastic telescopic it is only necessary to activation two pcrf, each pcrf activation 2 Bar signaling link, the load of every signaling link is 128xb% (it is assumed that 128xb% is less than 0.5), other pcrf Carry out dormancy, only monitor link re-establishment；Meanwhile, this dra only needs to apply for less vm virtual machine.
Figure 15 is signaling link according to embodiments of the present invention, virtual machine, the schematic diagram of telephone traffic synchronization, wherein, dra Network element needs to follow following principle, realizes the synchronization of signaling link, virtual machine, telephone traffic:
Even if virtual dra network element does not have load or only extremely low load it is also desirable to apply for minimum vm and signaling Link, these vm and signaling link never discharge or elastic telescopic.
When having low telephone traffic and need to apply for vm and signaling link, corresponding is all high priority, in whole service, The probability that application uses is very high.
When having middle telephone traffic and need to apply for vm and signaling link, corresponding is all medium priority.
When having Bulk Call and need to apply for vm and signaling link, corresponding is all low priority, in whole service, The probability that application uses is very low, only needs to apply in traffic peak, once peak period mistake, is immediately released.
It is consistent with vm with the change of telephone traffic due to signaling link, and linear, so, or Shen simultaneously Please, the migration of the signaling link between vm can or discharge simultaneously, be avoided to the full extent.
