Description
Technical field
The present invention relates to the communications field, particularly the double-attaching technology in control and the carrying separated network.
Background technology
Next generation network (Next Generation Network is called for short " NGN ") is a milestone of telecommunication history, and it indicates the arrival in new generation telecommunication network epoch.Angle from development, NGN is from traditional public switched telephone network based on circuit switching (Public Switched TelephoneNetwork, abbreviation " PSTN ") stepped gradually to paces in based on packet switching, it has carried all business of original PSTN network, great amount of data transmission is unloaded to internetworking agreement (Internet Protocol, be called for short " IP ") in the network to alleviate the heavy burden of PSTN network, the new features with the IP technology increase and have strengthened many old and new's business again.In this sense, NGN is based on time division multiplexing (Time Division Multiplexing, be called for short " TDM ") the PSTN speech network and the product that merges based on the packet network of internetworking agreement/asynchronous transfer mode (IP/ATM), it makes that integrated services such as voice, video, data become possibility on new generation network.At present, NGN becomes the focus of research.
In the NGN network architecture, introduced isolating construction, i.e. Media Gateway Controller (MediaGateway Controller is called for short " MGC ") and media gateway (Media Gateway is called for short " MGW ").
As NGN core technology MGC is a kind of distributed exchange and controlling platform based on software, and its notion is based on new network function model layering.MGC finishes CCF usually, and MGW finishes bearing function usually.A MGC can control a plurality of MGW by the H.248/MGCP protocol interface of standard, and the business that realized is separated with calling control.Wherein, MGC can be MSC-SERVER (mobile switching centre-server).
(the Mobile Switching Center of mobile switching centre, abbreviation " MSC ") the effect and the switching equipment of fixed-line telephone network have similarity, major function is that the mobile subscriber who is positioned at its controlled area is communicated control and management, the interface that connects other regional MSC and numerous base stations is provided, and to the exchange of continuing of calling out of mobile subscriber and information.
" dual-homed " is a kind of disaster tolerance mechanism that urgency communication can be provided when preventing Softswitch paralysis machine or burst fire-disaster accident (for example machine room fire, the telecommunication cable interruption that connects machine room, abnormal electrical power supply etc.) occurring, by the mutually redundant mode between the two cover soft switchcall servers that are in diverse geographic location, guarantee when wherein a certain Softswitch breaks down, another Softswitch can be come its professional all adapter, thereby guarantees that network is in urgent communication security constantly.In other words, in realizing dual-homed process, MGW can be registered to standby MSC-SERVER and finish follow-up call handling process under the situation of a MSC-SERVER fault.For guarantee MGW be registered to main with or standby MSC-SERVER after, the embedded signaling gateway function of MGW can correctly be forwarded to arrowband message the MSC-SERVER of corresponding registration, MGW need be configured to respectively main with and standby MSC-SERVER between link guarantee the correct follow-up message related to calls of transmitting.
" dual-homed " mechanism is a kind of safe disaster tolerance technology, can realize the disaster-tolerant backup in strange land, is difficult to realize that accidents such as earthquake, tsunami, the attack of terrorism are significant for dealing with and this ability is the traditional PSTN network.
In the prior art, generally all need to dispose two link set, one of them link set is configured to the MSC-SERVER of main usefulness, and another one is configured to standby MSC-SERVER; When the MSC-SERVER of main usefulness work, activate to main link with MSC-SERVER, the MSC-SERVER to main usefulness handles by this link set forwarding arrowband message related to calls; When standby MSC-SERVER work, activate to the link of standby MSC-SERVER, handle to standby MSC-SERVER by this link set forwarding arrowband message related to calls.Dual-homed in order to realize at present, need to main with configuration link collection all between MSC-SERVER and the standby MSC-SERVER, each link set all needs to dispose corresponding wideband link, guarantees that the function of the embedded SGW of MGW after dual-homing switchover can be transmitted the arrowband message related to calls to corresponding M SC-SERVER.
In this case, must dispose a link set respectively with MSC-SERVER and standby MSC-SERVER, will increase the complexity of configuration like this to main.And, when the appearance master is in state of activation with MSC-SERVER and standby MSC-SERVER, the forwarding message that the embedded signaling gateway function of MGW just can not be correct, Pei Zhi fault-tolerance is poor like this.
Summary of the invention
In view of this, main purpose of the present invention is to provide the dual-homed implementation method in a kind of control and the carrying separated network, makes that dual-homed configuration obtains simplifying, and saves the memory space of link set.
The further goal of the invention of the present invention is to carry out fault-tolerant processing to the abnormality that main/slave link all is activated in addition.
For achieving the above object, the invention provides the dual-homed implementation method in a kind of control and the carrying separated network, this network comprises at least one media gateway, with the primary, spare Media Gateway Controller that links to each other by at least one link respectively with this media gateway, described method comprises following steps:
A with described primary, spare Media Gateway Controller as a logic entity, be respectively link set of each described media gateway configuration, be used to realize and being connected of this logic entity that this link set comprises all links between this media gateway and this logic entity;
B realizes dual-homed switching by the link between direct activation or described media gateway of deexcitation and the primary, spare Media Gateway Controller.
Wherein, described step B further comprises following substep:
When needs from described main with Media Gateway Controller when standby media gateway controller is switched, described standby media gateway controller activates all links between itself and the described media gateway; Described main with all links between Media Gateway Controller deexcitation itself and the described media gateway.
In this external described method, described step B further comprises following substep:
When needs from described standby media gateway controller to main when switching with Media Gateway Controller, described master activates all links between itself and the described media gateway with Media Gateway Controller; All links between described standby media gateway controller deexcitation itself and the described media gateway.
In this external described method, also further comprise following substep in the described steps A:

Because MGW has different priority with link between the primary, spare MGC, so when abnormality that the link that occurs between primary, spare MGC and the MGW all is activated, the data of MGC can only be sent to mainly uses MGC, thereby reaches fault-tolerant effect.
Description of drawings
Fig. 1 is the related schematic network structure of dual-homed implementation method in control according to an embodiment of the invention and the carrying separated network.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The related network of control according to an embodiment of the invention and the dual-homed implementation method of carrying in the separated network as shown in Figure 1, this network comprises at least one MGW, and the primary, spare MGC that links to each other by at least one link respectively with this MGW.In this enforcement, as shown in the figure, MGC is MSC-SERVER.
The dual-homed implementation method of present embodiment comprises following steps:
A as a logic entity, is respectively link set of each MGW configuration with primary, spare MSC-SERVER, is used to realize and being connected of this logic entity that this link set comprises all links between this MGW and this logic entity.As seen, in the present embodiment, only dispose a link set at MGW to primary and backup MSC-SERVER when dual-homed.
Also further comprise following substep in the steps A:
Be main with the higher priority of link configuration between MSC-SERVER and the MGW;
Be the lower priority of the link configuration between standby MSC-SERVER and the MGW.
In conjunction with Fig. 1 as seen, link A and link B are respectively to main link with MSC-SERVER and standby MSC-SERVER, the priority height of link A, and the priority of link B is low, but they all are to belong to a link set that is configured to main with MSC-SERVER.
Creativeness of the present invention is embodied in: when the configuration link collection, only dispose a link set, in other words, only be configured to main link set with MSC-SERVER, but during the link in this link set of configuration, with MSC-SERVER with to standby MSC-SERVER configuration link all, wherein arrive the priority height of main link with MSC-SERVER to main, the priority of link that arrives standby MSC-SERVER is low.
B realizes dual-homed switching by the link between direct activation or deexcitation MGW and the primary, spare MSC-SERVER.In other words, when needs from main with MSC-SERVER when standby MSC-SERVER switches, standby MSC-SERVER activates all links between itself and the MGW, and is main with all links between MSC-SERVER deexcitation itself and the MGW.When needs from standby MSC-SERVER to main when switching with MSC-SERVER, mainly activate all links between itself and the MGW, all links between standby MSC-SERVER deexcitation itself and the MGW with MSC-SERVER.
Thus, under dual-homed situation, MGW can guarantee that signaling message can correctly be forwarded to the current MSC-SERVER that is registered to of MGW by disposing a link set.That is to say that if MGW is the current MSC-SERVER that is registered to main usefulness, then the embedded signaling gateway function of MGW is forwarded to signaling message the MSC-SERVER of main usefulness; If MGW is current to be registered to standby MSC-SERVER, then the embedded signaling gateway function of MGW with forwards to standby MSC-SERVER.
Specifically, with reference to Fig. 1, under normal situation, link A activates, link B deexcitation, and normal message is all handled by the MSC-SERVER that link A is forwarded to main usefulness.If dual-homing switchover has taken place, link A deexcitation this moment, link B activates, and normal message all is forwarded to standby MSC-SERVER by link B and handles.
As seen, the present invention only disposes a link set between primary, spare MGC and MGW, wherein comprise all links that MGW leads to primary, spare MGC respectively, by directly link activation and deexcitation being realized active and standby switching, and be MGW and main with the higher priority of link configuration between the MGC, be the lower priority of link configuration between MGW and the standby MGC.In actual disposition, just can reduce the configuration of link set like this, not need all configuration links of primary and backup MSC-SERVER.
On the other hand, in this configuration, if be in abnormal conditions, the master is in state of activation with MSC-SERVER and standby MSC-SERVER, this moment, link A and link B also were in state of activation, because the priority height of the priority ratio link B of link A, this moment, signaling message was all handled by the MSC-SERVER that the high link A of priority is forwarded to main usefulness, avoided occurring under the situation of dual-active signaling message and transmitted the problem of makeing mistakes.
Owing to only disposed a link set in the foregoing description, lack than the prior art scheme and join a link set, so configuration is more simple, maintenance is convenient.And link set itself is to need certain memory space, when the MGW number can be saved considerable memory space more for a long time.In addition, because MGW has different priority with link between the primary, spare MGC, so when abnormality that the link between primary, spare MGC of appearance and the MGW all is activated, the data of MGC can only be sent to lead uses MGC, thereby reaches fault-tolerant effect.
Though by with reference to some preferred embodiment of the present invention, the present invention is illustrated and describes, those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
