Embodiment
The embodiment of the invention can be logically divided into physics MGW a plurality of virtual MGW in the specific implementation process, and gives described virtual MGW with the resource distribution of physics MGW, and described a plurality of virtual MGW are registered in a plurality of MSC server respectively; The a plurality of virtual MGW of described a plurality of MSC server administration to its registration, that is, described a plurality of MSC server can share the resource of virtual MGW of oriented its registration.
Be elaborated to accompanying drawing 5 pairs of described methods of the embodiment of the invention, system and equipment below in conjunction with accompanying drawing 2.
Fig. 2 is the IU FLEX networking plan schematic diagram that media gateway resource is shared in the first embodiment of the invention, comprises n MSC server and m physics MGW (m 〉=1, n 〉=2) in the networking shown in Figure 2;
In the specific implementation process of first embodiment of the invention, m physics MGW can be carried out virtually respectively, each physics MGW is n virtual MGW by logical partitioning, and gives described virtual MGW with the resource distribution of physics MGW; If virtual MGW is n, this n virtual MGW is registered in n MSCserver respectively, and these virtual MGW logically are separate;
Like this, each the MSC server in the embodiment of the invention has administered m the virtual MGW to its registration, and promptly MSC server can use all these m the resources to the virtual MGW of its registration.When wherein certain MSC server breaks down, fault MSC server cannot use the resource of the oriented virtual MGW that it was registered, but can not influence other MSC server, other MSC server can also use all to belong to the resource of the virtual MGW of its administration; Such as, when MSC server-1 broke down, other MSC server still can use the resource of the virtual MGW of its administration;
Certainly, when physics MGW is carried out logical partitioning, also can be with physics MGW logical partitioning greater than n virtual MGW, so just have at least two virtual MGW to be registered in a MSCserver simultaneously.
Fig. 3 is the IU FLEX networking plan schematic diagram that media gateway resource is shared in the second embodiment of the invention, comprises the MGW of n MSC server and m physics in the networking shown in Figure 3;
In the specific implementation process of the embodiment of the invention, each physics MGW can be logically divided into two virtual MGW, be registered in two MSC server respectively, such as, MGW-1 is two virtual MGW by logical partitioning, these two virtual MGW are respectively to MSC server-1 and MSC server-2 registration, in like manner, MGW-1 also is divided into two virtual MGW, these two virtual MGW are respectively to MSC server-1 and MSC server-2 registration, like this, MSC server-1 and MSC server-2 have just administered two virtual MGW respectively, when one of them MSC server breaks down, can not influence the resource that another MSC server uses its virtual MGW that administers.
Here, only with RNC to same MSC server the quantity of virtual MGW of process all be all example mutually and describe, but those skilled in the art will be appreciated that, when networking, can decide the quantity of virtual MGW according to different situations, promptly, the quantity of the virtual MGW that different RNC passes through during to same MSC server can be identical or different, same RNC to different MSC server the time the quantity of virtual MGW of process also can be identical or different.
Fig. 4 is the IU FLEX networking plan schematic diagram that media gateway resource is shared in the third embodiment of the invention, comprises n MSC server and a MGW in the networking shown in Figure 4; In the specific implementation process of the embodiment of the invention, when having only a physics MGW, can be n logic MGW with this physics MGW logical partitioning, be registered in n MSC server respectively, promptly each MSC server administers a virtual MGW respectively; Such as, when MSC server-1 broke down, other MSC server can use the part resource of this physics MGW equally, i.e. the resource of the virtual MGW that registered to other MSC server.
This network construction form that has only a MGW is suitable for operator's networking to be used during the initial stage, because be not a lot of networking initial stage user, traffic carrying capacity is not very big, uses this kind networking can save operator's networking cost; When the number of users of operator's development increases gradually, can reach the stability that increases power system capacity and system by the quantity that increases physics MGW.When increasing physics MGW, a physics MGW who only needs to increase carries out virtual, and registers just passablely to corresponding M SC server, can not influence the operate as normal of existing network.
In the embodiment of the invention, at this moment the quantity that physics MGW is logically divided into virtual MGW also can, have at least two logic MGW to be registered among the same MSC server greater than the quantity of MSC server.
In the specific implementation process of the embodiment of the invention, when physics MGW being logically divided into a plurality of virtual MGW, can adopt multiple zoned format, as, can carry out logical partitioning to physics MGW according to demands such as capacity, function, performances; Also can carry out logical partitioning according to the IP/ATM/TDM bearing resource; Can also adopt the mode of resource pool to carry out logical partitioning according to resources such as media resource TC/EC/ conf bridges.As for the specific implementation process of logical partitioning, existing ripe solution is not that the embodiment of the invention will be paid close attention in the prior art, has not just elaborated herein.
In the specific implementation process of the embodiment of the invention, except the resource-sharing that can realize virtual MGW, can also realize sharing of user's face resource between radio network controller (RNC) and the virtual MGW and signaling plane resource; At this moment need to satisfy: user's face resource between RNC and each the physics MGW and signaling plane resource multiply by m-1 respectively (m equal except 1, wherein m is the quantity of physics MGW in the network), be not less than user's face resource summation and signaling plane resource summation between all MSC and the RNC; When m=1, the resource summation when the resource sum between RNC and this physics MGW must satisfy all MSC and works independently.
When the number of MGW is a plurality of, i.e. m 〉=2 o'clock, the embodiment of the invention can also be evaded the Single Point of Faliure problem except realizing the resource-sharing, specifies below.
(1) certain physics MGW breaks down in network, and MSC server can also select to use the resource of other virtual MGW, thereby makes the whole system operate as normal;
Be exactly that after physics MGW was a plurality of virtual MGW by logical partitioning, described a plurality of virtual MGW were respectively to a plurality of MSC server registrations specifically.If certain physics MGW breaks down, this physics MGW just can't provide resource service for the MSC server of its registration so, but MSC server this moment can also use other the resource to the virtual MGW of its registration.MSC server can be according to the resource ratio of different virtual MGW configuration when using the resource of other MGW, and load sharing uses the resource of a plurality of virtual MGW or preferentially uses the resource of certain virtual MGW.Such as, when MGW-1 breaks down among Fig. 2, because other MGW registered to it by the form of virtual MGW, so MSC server-1 can also use all virtual MGW resources of registering to it.
(2) all dispose MC interface (such as the H248 interface) between MSC server and a plurality of physics MGW, MSC server controls the resource of virtual MGW by described MC interface; If wherein certain MC interface breaks down, though MSC server can't continue to use the resource of the virtual MGW that is connected with fault MC interface, MSC server can also select to use the normal MGW of other MC interface; Can reach the MC interface fault between MSC server and one of them the physics MGW like this, only influence MSC server the resource of this MGW is used, can not have influence on the use of MSC server the normal MGW resource of other MC interface; And because the MC interface between other MSC server and this MGW is normal, so other MSC server can also continue to control and use the resource of this MGW.Such as, when the MC interface between MSC server-1 and the MGW-1 breaks down, MSC server-1 can not use the resource of MGW-1, but because the MC interface between MSC server-1 and other physics MGW is normal, so MSC server-1 can also use other resource to the virtual MGW of its registration by normal MC interface; Simultaneously, for other MSCserver except that MSC server-1, because MGW-1 is normal with the MC interface of other MSC server, so MGW-1 still can provide resource to other MSC server.
(3) when M3UA between MSC server and the physics MGW (Message Transfer Part third level user adaptation layer) link occurs fault or MTP3-B (3 grades of the message transfer parts) link occurs fault between RNC and a plurality of physics MGW, do not influence the function of this MSC server;
Be exactly specifically, all dispose the M3UA link between MSC server and a plurality of physics MGW, all dispose the MTP3-B link between RNC and a plurality of physics MGW, a plurality of virtual MGW share described M3UA link and MTP3-B link, virtual MGW transmits the IU interface signaling between MSC server and the RNC as SG (Signalling Transfer Point);
When the M3UA link failure between MSC server and certain the physics MGW, MSC server does not just pass through faulty link, from the IU interface signaling between this virtual MGW forwarding MSC server and the RNC, but transmit from other virtual MGW by normal M3UA link.
When virtual MGW transmitted the IU/A interface signaling, MSC server can use M3UA link route priority to reach between a plurality of virtual MGW, a plurality of virtual MGW of the selection of load sharing or preferentially select a virtual MGW to transmit the IU interface signaling and give RNC; RNC can use MTP3B link route priority to reach a plurality of virtual MGW of selection of load sharing or preferentially select a virtual MGW to transmit the IU interface signaling and give MSCserver simultaneously.
In the embodiment of the invention, can also between RNC and each MSC Server, increase a direct-connected IP/ATM/E1 carrying, the interface of configuration IU interface signaling face.Like this, MSC server just can not pass through MGW, directly the IU interface signaling is sent to RNC.
In the specific implementation process of the embodiment of the invention, MSC server is carrying out call treatment, and when increasing user's face resource of MGW, the principle of selecting MGW is Calling Side and the identical MGW of the preferential selection of callee side; Specify below:
For office call, if which virtual MGW Calling Side resource and callee side resource do not determine all that on MSC server preferentially is chosen in same virtual MGW and goes up increase Calling Side and callee side resource, reaches the purpose that office call takies identical virtual MGW resource.If the Calling Side resource has determined that when certain virtual MGW then MSC server preferentially is chosen in this virtual MGW and goes up increase callee side resource; If the callee side resource has determined that on certain virtual MGW then MSC server preferentially is chosen in this virtual MGW and goes up increase Calling Side resource.
For outbound call or incoming call, if which virtual MGW Calling Side resource and callee side resource do not determine all that on MSC server preferentially is chosen in same virtual MGW and goes up increase Calling Side and callee side resource; If the callee side resource has determined that on a fixing virtual MGW then MSC server preferentially selects this fixing virtual MGW when local office is increased the Calling Side resource.
For transit call, if which virtual MGW Calling Side resource and callee side resource do not determine all that on MSC server preferentially is chosen in same virtual MGW and goes up increase Calling Side resource and callee side resource; If in two office directions the Calling Side resource of an office direction or callee side resource being arranged is to determine on certain virtual MGW, then MSC server preferentially selects this virtual MGW when increasing the resource of another office direction.
MSC server is being certain virtual MGW when increasing resource, increases the resource failure owing to reasons such as virtual MGW resource congestion, resource be unavailable cause, and MSC server can reselect on the virtual MGW of other normal operation increases related resource.
