In agreement H.248, the bearing resource on the MGW is conceptualized as Termination, and promptly end points distributes ID to identify by gateway voluntarily, and MGC quotes the bearing resource on the MGW by described ID and operates on it.
In addition, a physics MGW, promptly PMGW can form a plurality of virtual MGW, i.e. VMGW by the mode of logical partitioning.A PMGW who does not do any division can whole treat as a VMGW, and at this moment, that see from the MGC angle all is VMGW.After logical partitioning, the resource of PMGW, as: bearing resource, playback/number receiving resource, encoding and decoding conversion resource, conferencing resource or the like, may between VMGW, share, also may be allocated to certain specific VMGW and use.For the PMGW resource of not carrying out logical partitioning, then can regard all types of resources as and all be allocated to a unique VMGW use, its schematic diagram is as shown in Figure 2.
For the processing of bearing resource, at present, ATM (asynchronous transfer mode)/IP bearing resource generally all adopts the strategy of sharing, and has then taked to divide the mode of using for TDM (time division multiplexing) bearing resource.This is that technical characterictic by bearing resource itself decides.
For the ATM/IP bearing resource, all nature items can be placed in the big natural pond and manage.When MGC need call, notice MGW took out the nature item that needs from described POOL, discharged after application is finished and went back.Select which Item by MGW decision, and each Item that selects for MGW, at MGC and indistinction.
And for the TDM bearing resource, each Item needs configuration on MGC, MGC need understand the corresponding relation of Item and VMGW, in the time will calling, be responsible for choosing by MGC, having chosen an Item and also just selected a VMGW, is exactly the scope of having selected an Item and ought select a VMGW, then selects an Item to be taken from this scope.Monopolizing of described TDM bearing resource used schematic diagram as shown in Figure 3.The a plurality of different VMGW that one of them PMGW is come out by logical partitioning can be controlled by identical MGC, also can be controlled by different MGC, and N VMGW controlled (M<=N) simultaneously among Fig. 3 by M MGC.
This piecemeal is divided but not problem that the occupation mode shared causes is that in case the ownership VMGW fault of resource, then this resource is promptly lost, and can not be used further to business.The fault schematic diagram as shown in Figure 4.And in fact, fault be not resource itself, such as the control treatment module fault that may be this VMGW.It can be come into operation again, use such as being allocated to other still normal VMGW.
And by present technology, when this problem occurring, have only by manual intervention, such as giving another VMGW with this part resource division again by configuration, the resource of this waste could be come into operation again, this kind method is because before manual intervention is implemented and come into force, these resources are in by idle state always, have caused negative effect when high reliability is used.
