Description
Technical field
The present invention relates to flexible exchanging network, relate in particular to a kind of flexible exchanging network and network-building method thereof.
Background technology
Mobile soft switch is the circuit domain important link in the 3G conversion in the mobile core network, soft switch has realized call bearer and has called out separating of control, simultaneously, it also encapsulates Internet resources, network capabilities, business interface by open standard links to each other with service application layer, thereby new business can be provided on network easily fast.In addition, it is exactly that server (SERVER) can be concentrated setting that the proposition of soft switch also has a typical feature, thereby is convenient to safeguard.Concentrate setting just because of SERVER; make SERVER to back up and to protect; the protected mode of existing soft switch SERVER has three kinds: active and standby, be equipped with and the method for server pools (SERVER POOL) mutually; it is active and standby and mutual that to be divided into 1+1 again fully active and standby; N+1 is active and standby, and 1:1 is equipped with mutually and N:1 is equipped with four kinds of modes mutually.
The method of SERVER POOL needs SERVER and base station controller (BSC) all to share, and requires the support of IP bearer network, though be a kind of good protection and network's mode, condition does not also possess at present.That adopts at present is generally active and standby or is equipped with mode mutually.
The pattern that is provided with of existing soft switch is generally SERVER and concentrates the mode that is provided with, and backup mode adopts working method active and standby or that be equipped with mutually.The mode of operation that is equipped with mutually; because under the situation that a SERVER breaks down; its media gateway of administering (MGW) need belong to another standby SERVER again; and the signalling point difference of these two SERVER; so need the data of the BSC under the MGW be reconfigured in execute protection, if the quantity of BSC is bigger, quantities is just very big; also can't play the effect of real-time guard, so generally also do not advise adopting.So existing set-up mode is generally active and standby mode of operation, lead the different machine rooms that are separately positioned on same city with SERVER and standby SERVER, the centre links to each other by converging the ring dispatch circuit.Because under the situation that the active and standby operation principle of N+1 is a master to break down with SERVER, standby SERVER starts, except N master can share the standby SERVER with SERVER, its backup principle and 1+1 do not have the difference of essence, so followingly analyze with regard to the active and standby mode of 1+1.
The main-apparatus protection scheme of SERVER is divided into two-layer, and one deck is the masterslave switchover of SERVER, and another level is the difference ownership of MGW.Wherein the masterslave switchover of SERVER is the quality that detects the main SERVER of using by the mode of heartbeat line (Heartbeat) in real time, but the still main fault of the fault of heartbeat line with SERVER, standby SERVER can't differentiate, and in the historical facts or anecdotes border, all can adopt manual mode of switching to implement protection; The attaching problem of MGW then solves by the dual-homed mode that MGW belongs to active and standby SERVER simultaneously, as shown in Figure 1, logically, MGW1 and MGW2 belong to active and standby SERVER simultaneously, each MGW articulates several BSC/NodeB, has wherein omitted the BSC/NodeB that MGW2 articulated.
Dual-homed set-up mode only is a logical course, in the deployment of real network, MGW follows H.248 agreement to the interface of SERVER, and promptly the mode by IP realizes, current, two dual-homed IP paths all are that the SDH (Synchronous Digital Hierarchy) (SDH) by existing network is dispatched.As shown in Figure 2, the MGW in city 1, city 2, city 3 inserts the SDH passage by bifurcated multiplexer (ADM) respectively.
In the existing actual deployment, be in the purpose of centralized management and O﹠M, SERVER is deployed in core or provincial capital, MGW can close to establish also can divide and be arranged with SERVER, generally speaking, MGW is deployed in each different districts and cities, and we discuss SERVER and MGW not in the situation in a city.MGW is connected on two routers, and POS (the Packet Over SONET/SDH by these two routers, packet bearer is on synchronous digital transmission) mouthful and the ADM of this locality link to each other, SDH by the ADM place encircles demodulation circuit to city, SERVER place then, then be connected to router back-to-back by ADM, router is connected respectively to active and standby SERVER again.In the above-mentioned annexation, ADM1 among Fig. 2 and ADM1 ' may be in same machine rooms, also may be in different machine rooms, also may be the ADM in the different system in the same machine room, even may be same ADM in the same system, this depends on the SDH system organization or the outgoing route in MGW or city, SERVER place.
Because in the existing network, the outgoing route in a lot of cities only is two physics routes, like this, be subjected to the restriction of physics route, even there is multisystem, also be different wavelength-divisions or the overlapping networking mode of different SDH, like this under the situation that the double route of SERVER striking out interrupts, route as 31 places of the cross among Fig. 3 and cross 32 places has all been interrupted, and will cause the communication of the MGW region that articulated all to be interrupted, as 3 MGW among Fig. 3, and under the situation of traditional MSC switch, the interruption of some cities outgoing route only can cause the out communication disruption in this city, and other are not affected.So, the SERVER of soft switch concentrates set-up mode to bring very big risk to system, but this current only be that device backup by SERVER solves, and be backup in same city, do not consider the risk that link failure brings to soft switch, even recognize, corresponding solution is not proposed yet.
By anatomizing discovery, Softswitch itself has possessed comparatively complete protection mode, and the risk that SERVER concentrates setting to bring mainly causes owing to having the transmission system imperfection now.Addressing this problem can be by improving transmission network, promptly between each MGW and SERVER, all should possess 3 different physics routes, but the huge investment of perfect needs of transmission system, and some local because restriction of geographical conditions (such as mountain area, ocean) etc., can't make up three incoherent routes of physics; In addition, even conditions permit also needs the very long construction period.
Summary of the invention

Embodiment
In flexible exchanging network, new SERVER is set considers all generally whether the situation of business development and the place of new SERVER possess the O﹠M ability, and do not consider the problem that transmission network is whether perfect.The present invention considers emphatically whether transmission network is perfect, and then proposes how the strange land is provided with the method for standby SERVER and the method for MGW ownership.
Among the present invention, same optical cable or same ducted system are called a physics route.
Determining that a city is provided with under the situation of SERVER formation flexible exchanging network, according to the business development needs, new SERVER need be set, the invention provides a kind of method that new SERVER is set.The city that has three and three above physics routes can arrive the SERVER that has been provided with no longer is provided with new SERVER in principle, MGW only is set, and belongs to this SERVER; Do not possess the city of three uncorrelated routes of physics to this SERVER, then analysis-by-synthesis business development and O﹠M ability consider to be provided with new SERVER.
Among the present invention, having only two physics routes to arrive in the city in the city, SERVER place that has been provided with, if do not exist between two cities and have three routes or three cities that route is above, then these two cities are close to the city each other mutually, and described any that is close to mutually each other in the city is called and is close to the city mutually.City, SERVER place that a plurality of arrival have been provided with the city in, newly-increased SERVER preferentially is arranged on and is close to the city mutually.In addition, also will foundation and the method to set up of this SERVER " non-conterminous and at interval " determine the place that is provided with of new SERVER, promptly only possess in the city of two routes at these, new SERVER set-point can not be close to the city at this SERVER place, satisfies method to set up simultaneously: new SERVER set-point is clipped in the middle with next-door neighbour's the city mutually that the SERVER loca that has been provided with will only possess other two routes as far as possible; And when other these cities are provided with MGW, require to belong to new SERVER, promptly new SERVER uses SERVER as their main, and its standby SERVER then will be arranged on the above-mentioned city of having determined to be provided with SERVER.
In other words, at a city M soft switching server is set and constitutes a flexible exchanging network; Arrive the media gateway that described city M possesses the city of three or three above physics routes, belong to the described soft switching server that is arranged on described city M; Increase a new soft switching server at city X, described city X is for being close to one of city mutually, and between described city X and the described city M at least one at interval have only two physics routes to arrive the city of described city M; Belong to described new soft switching server with the media gateway of described city X and with media gateway that described city X is close to the city in city each other mutually.
The principle of SERVER main-apparatus protection mode is a SERVER only to be arranged in work at a time point; promptly only a signalling point is set for active and standby SERVER; this mode is because SERVER research and development time has only been considered equipment fault, and do not considered the fault of link.Because the equipment (standard that comprises soft switch) of current all soft switch is provided with a signalling point all only for active and standby SERVER, does not promptly consider active and standby mode of working simultaneously.But in actual applications, in order to reduce the excessive risk that SERVER concentrates setting to bring, the present invention has adopted the SERVER strange land that the mode of backup is set, and under this setup, need active and standbyly working simultaneously, it is minimum to drop to the loss that network link failure brings.
After adopting network-building method of the present invention, when only two the physics routes in a certain city of appearance all break down, then need the active and standby SERVER of newly-increased SERVER to work simultaneously, promptly will reinstate standby SERVER.
Suppose to be provided with in the SERVER complete set, then as long as will interrupt (comprising in out and the territory) fully with the communicating by letter of MGW institute region that SERVER can't be communicated with.And after adopting network-building method of the present invention, active and standby SERVER takes identical signalling point, but do not support identical signalling point to work simultaneously, then according to active and standby operation principle, active and standby SERVER does not work simultaneously, when the double route link failure takes place, with the whole interruptions of the communicating by letter of the obstructed city, MGW place of the SERVER of operate as normal (out and territory in).If but support identical signalling point to work simultaneously, then, then can solve the communication disruption problem that link failure brings because primary and backup SERVER works simultaneously, out communication and intra-area communication can not be affected.If active and standby SERVER adopts different signalling point work, also can solve the communication disruption problem that link failure brings, improve the survivability of network, but the MGW in some city is when belonging to standby server again, the BSC that MGW articulates need reconfigure.
If adopt identical signalling point to work simultaneously, when the double route link failure takes place,,, also can not cause the confusion of route on graph theory so identical signalling point is worked simultaneously because the master is disconnected with SERVER and standby SERVER fully.Because active and standby SERVER does not administer all MGW, its webmaster demonstration only for the equipment fault of these management less than MGW, can shield from webmaster.
And when fault restoration, only need to turn off standby SERVER to get final product, and the SERVER of main usefulness it goes without doing any action is not high to main O﹠M Capability Requirement with SERVER, this also is as one of main reason with SERVER the new SERVER that is provided with.
Method of the present invention can also be used for existing network, exists the network of two above SERVER to adjust in different cities.
Network-building method in a kind of flexible exchanging network of the present invention may further comprise the steps:
In the described step 3, described new soft switching server is used server as main, and the standby server of described new soft switching server is arranged on described city M.
In the described step 3, will be close to all cities selections in city each other mutually between described city M and described city X with described city X.
The main signalling point with server and standby server of described new soft switching server is set to identical signalling point.
The main priority that is higher than standby server with the priority of server of described new soft switching server is set.
The main signalling point with server and standby server of described new soft switching server is set to different signalling points.
With having only two physics routes to arrive the media gateway in the city of described city M, in described step 4, belong to the media gateway of described new soft switching server, belong to the described soft switching server that is arranged on city M.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
The topological structure of supposing existing network as shown in Figure 4, through observing, city 1, city 2, city 3, city 4 and city 5 all have 3 physics routes to arrive the city M at server 1 place, city 6, city 7 and city 8 have only two physics routes to arrive server 1 place city M, and city 6, city 7 and city 8 next-door neighbour's city mutually each other.Now new SERVER to be set, because had better not be when new SERVER is set near the city M at server 1 place that exist, so city 8 is not suitable for being provided with new SERVER, again according to the method to set up of new SERVER, newly-installed SERVER and the SERVER that has existed will will have only the city of two physics routes to be clipped in the middle as far as possible, so city 6 is fit to be provided with new SERVER, promptly city 6 can be used as the city X that new SERVER is set.Therefore the main SERVER that use of new SERVER promptly can be led and being arranged on city 6 with server 2, and with the backup of this SERVER, promptly standby server 2 is arranged on the city M at server 1 place.If city 7 or city 8 are provided with MGW, then its master should be main with server 2 with SERVER, and its standby SERVER is a standby server 2.
As shown in Figure 5, if newly-installed SERVER promptly leads the city M that also is arranged on server 1 place with server 2, if the double route fault at cross 51 shown in Fig. 5 and cross 52 places, the meeting of communicating by letter in city 6 and city 7 is all interrupted.And as shown in Figure 6, the master in city 7 and city 8 is located at city 6 with SERVER is promptly main with server 2, standby SERVER is that standby server 2 is established server 1 place city M in the drawings, if the cross 61 shown in Fig. 6 and the double route fault at cross 62 places, because city 7 place MGW still can communicate by letter with the SERVER in city 6, so communicate by letter and can not be affected with communicating by letter of 6 in city in its this locality.If do not support identical signalling point to work simultaneously, its standby SERVER can not start, and the communication of the MGW of the MGW region within the jurisdiction of city 8 settings will all be interrupted like this.If support the mode that identical signalling point is worked simultaneously, in Fig. 6 under the situation of two point fault (being that city 6 and city 7 and other parts are not communicated with fully), the SERVER in city 6 still works, its standby SERVER also starts simultaneously, because active and standby SERVER does not physically communicate, so identical signalling point work can not cause the route confusion yet, and equipment is also supported this mode fully.In this case because signalling point do not become, so the data configuration of the BSC/NodeB that city 7 and city 8 are had jurisdiction over also need not to do any change just can operate as normal, can not cause communication interruption.And because the master can't see city 8 with SERVER, with regard to the situation that the MGW that is equivalent to city 8 breaks down, standby SERVER can't see city 7, and the situation with regard to the MGW that is equivalent to city 7 breaks down can get final product these alarm shields from webmaster.
When fault recovery, only need turn off standby SERVER and get final product, city 6 main with SERVER it goes without doing any action, thus minimizing and is put into city, the stronger server of O﹠M ability 1 place to the requirement of most of O﹠M to the requirement of city 6 O﹠Ms.
For identical signalling point is worked simultaneously, striking out communication when above-mentioned processing can solve the double route fault is to a great extent communicated by letter with local, for Incoming communication, by the priority of active/standby server is set, can solve incoming call to the city 8 Incoming communication issue, promptly the master of newly-increased SERVER is higher than the priority of standby SERVER with the priority of SERVER, when calling out the user in city 8, according to signalling point, find in the city 6 the main SERVER that uses earlier, when discovery can not connect, find the standby SERVER of this master again, thereby solved the Incoming communication issue in city 8 with SERVER.
Certainly, main shown in Fig. 6 also can adopt different signalling points with server 2 with standby server 2, the fault shown in Fig. 6 appears and after, when 8 MGW belonged to standby server 2 in the city, the BSC that MGW articulated in city 8 need reconfigure.
Fig. 7 is optical cable figure of Liaoning Province and conventional soft switch networking diagram.In traditional networking diagram, Liaoning Province is divided into two Da Qu: Shenyang and Dalian, and the Shen Yangda district is all returned in Huludao City, Jinzhou, Panjin, Chaoyang, Fuxin, Tieling, Fushun, and all the other return the Da Lianda district.In Shenyang and Dalian SERVER is set respectively, other areas are provided with MGW, and attaching relation is provided with according to big section planning relation.
Be not difficult to find out, only there are two different physics routes in Yingkou, Anshan, Liaoyang, Benxi and Dandong to Dalian, if between Dalian and Dandong, break down simultaneously between Dalian and Yingkou, then above-mentioned 5 places will be out of touch with Dalian, and this locality communication in these places will all be interrupted with out communication.
Anatomize the network topological diagram in Liaoning, all there are 3 different physics routes in Yingkou, Anshan, Liaoyang to Shenyang, then according to the affiliation method of MGW, the MGW that these 3 cities are provided with should belong to the SERVER in Shenyang, just can reduce the probability of malfunction in these 3 cities.The SERVER that Dandong and Benxi belong to Dalian only is set, and the method that is provided with according to standby SERVER strange land is set to Shenyang to the standby SERVER of Dalian SERVER again, so just can improve the fail safe of network well.
Again the network structure after the networking as shown in Figure 8.
Under this networking structure, (Benxi communication disruption) appears interrupting in two striking out in (Dandong communication disruption) or Benxi simultaneously unless two striking out in Dandong are out of order simultaneously, under other situations, even occur the double route fault in the Da Lianda district, communication can not be affected yet.Break down simultaneously as linking Yingkou greatly and linking Dandong greatly, the standby SERVER in Shenyang will take over the MGW in Dandong and Benxi, and communication can not be affected.
Linking Yingkou and Dandong greatly under the cross 91 and the situation of cross 92 double route faults that occur simultaneously between Benxi as shown in Figure 9, the MGW in Benxi has broken away from the main administration with SERVER in Dalian, but Dandong is also among administration, so it is main with SERVER still operate as normal, and because above-mentioned fault causes Dalian and other areas of Dandong and Liaoning from physically separating, so enable the standby SERVER in Shenyang, make the area, Benxi also can operate as normal.Under the situation that does not have to repair in fault, if the pattern that newly-increased active and standby SERVER adopts identical signalling point to work simultaneously, in this case, for out and local communication, because signalling point does not change, so the configuration of the BSC that the MGW in area, Benxi articulates also need not to do any change; For Incoming communication, the main priority that is higher than standby SERVER with the priority of SERVER can be set, thereby solve the problem that signalling point can't be determined, Benxi of making a telephone call to, Beijing for example, the main SERVER that uses that can find earlier in Dalian, when discovery can't be connected, the standby SERVER that finds again in Shenyang.And when fault restoration, only need standby SERVER with Shenyang close and get final product, the SERVER in Dalian need not to do any action.Certainly newly-increased active and standby SERVER adopts different signalling points, the fault shown in Fig. 9 appears and after, when the MGW in area, Benxi belonged to standby server, the BSC that MGW articulated in area, Benxi need reconfigure.As can be seen from the above analysis, SERVER remote backup mode is that the long term growth (SERVER being set more than the three unities) of soft switch provides good networking foundation.
