Description
Technical field
The present invention relates to call-center technology field more particularly to a kind of multi-node disaster tolerance method and NGCC (Next
Generation Call Center, Next Generation Call Center) node.
Background technique
It in the prior art,, can be due to the physics when carrying out the concentration deployment of NGCC single node for NGCC platform
Nodes break down and cause all-calls business will interrupt, therefore, risk is relatively high；Meanwhile when attending a banquet larger,
It is not recommended that by all-calls service set on single call platform；For this purpose, in the calling of construction multinode separate service deployment
The heart is imperative.
Referring to Fig. 1, the case where being multiple NGCC node deployments, this is sentenced for two NGCC nodes.In NGCC multinode
In deployment, for each NGCC node, it is independently deployed with CC-MGW (the Call Center Media of oneself
Gateway, call center's Media Gateway), CC-MGCF (Call Center Media Gateway Control Function,
Call center's Media Gateway Control Function), C3F (Call Center Control Function, call center's control function),
MAGW (Media Access Gateway, Media Access Gateways) equipment, and core network access and CMNET, each CC-MGW,
CC-MGCF is connected to the C3F of some corresponding NGCC node, receives the management of the C3F.Pass through IWC3F (Call between multiple nodes
Center Control Function Interworking Gateway, call center control Interworking gateway) interconnection, thus real
Traffic scheduling and user data delivery between existing multinode.Wherein, IWC3F is mainly responsible for the seat between multiple call centers
Seat scheduling and telephone traffic transfer.The switching of traffic is completed by core net between each NGCC node, and each seat, which is connected to, corresponds to certain
The C3F of a NGCC node, receives the scheduling of the C3F.
When being worked normally in each NGCC node, but traffic overflow situation occur, if the one turn of manual calling of NGCC node is excessive,
Manual service resource capability is insufficient, and the Service Source information collected by IWC3F and strategy are judged, circuitous from node one by calling
Revolution is connected to node two, to utilize the Service Source of node two.
When the C3F failure of NGCC node one, the calling detour for being linked into this node CC-MGW is transferred to by CC-MGCF
NGCC node two is handled, to realize traffic disaster tolerance.
However, there are the following problems for meeting for above-mentioned multiple NGCC node deployments:
1) traffic mutual assistance causes extra resource expense between each NGCC node
Between each NGCC node when traffic mutual assistance, Media Stream and signaling flow need between two NGCC nodes detour, cause across
Node bandwidth occupies more, equipment of the core network load increase, the increase of CC-MGW, CC-MGCF treating capacity, and then causes a large amount of additional
Resource overhead.
2) See-saw effect of service flexibility and resource overhead
The flexibility angle either carried out from business considers, or from node failure when reduces the influence angle to business
Consider, being intended to same business can be carried jointly by multiple NGCC nodes；But by same service deployment in multiple NGCC nodes
On certainly will increase the number of traffic mutual assistance between node.Resource volume when this just unavoidably produces service flexibility and traffic mutual assistance
The See-saw effect of overhead.
3) resource dynamic capacity-expanding and allotment between node be cannot achieve
After building multiple NGCC nodes call center, same line of business is generally carried on multiple nodes by region division.?
When region telephone traffic changes, the resource of palpus dilatation corresponding node cannot achieve resource dynamic capacity-expanding and allotment.When certain node computer room
When the necessary resources such as space or electric power are unsatisfactory for dilatation demand, node need to be created and can not be by other nodes sharing resources of dilatation
Mode solve.
4) resource of attending a banquet and traffic node binding
Seat resource is fixed to check in a certain traffic node, when a problem occurs, such as one queue machine of NGCC node or C3F event
Barrier, traffic will be all sent to NGCC node two by core net；But due to attending a banquet, resource and NGCC node are bindings, are checked at this time
The resource of attending a banquet of node one will be unavailable.Due to the reduction for resource of attending a banquet, artificial telephone traffic percent of call completed will decline, or even traffic occur
Call loss.
5) manual intervention is needed when node disaster tolerance and delay is larger
Due to seat resource and traffic node binding, when a certain node failure, the seat resource for checking in the node will be complete
Portion is checked out.To avoid the problem that artificial percent of call completed decline caused by seat resource is reduced, seat, which need to change, checks in other traffic sections
Point needs the IP address of manual amendment's seat check-in and is checked in manually.
