According to the method and the device of the invention, the resource sharing and the load balance are effectively realized, the number of the mobile management is reduced, the position updating and switching are reduced, the complexity of the network planning is reduced, and the networking is convenient without changing the MSC server and the BSC.
Description
Technical field
The present invention relates to mobile communications network, relate in particular to based on the media gateway in the mobile communications network of soft switch.
Background technology
For existing mobile operator, Softswitch technology is introduced the mobile local net, for its problem that solves the existence of 2G switching network provides opportunity.In the most original mobile flexible exchanging network structure, suppose to have two MSC (mobile switching centres, Mobile Switching Center) server, each MSC server connects two media gateway (MGW, Media Gateway), each media gateway connects two BSC (base station controller), in real life scenarios, each MSC server can connect a plurality of media gateway, and each media gateway can connect a plurality of BSC.Each MSC server covers different coverages, in case one of them MSC server breaks down, just can't communicate between the BSC in the coverage that is covered by this MSC server and this MSC server.
In order to address the above problem, the solution of a kind of N+1 (N=2) backup network has been proposed in the prior art, N+1 as shown in Figure 1 (N=2) backup networking plan is meant that the MSC server carries out networking in the mode of " N main usefulness, 1 as pure backup ", promptly " N " individual MSC server is as main usefulness, and last " 1 " individual MSC server is as the backup of other N MSC servers.Among Fig. 1, media gateway is called active link with the link that is connected between the MSC server, media gateway is called reserve link with the link that is connected between the MSC backup server N+1, and each MSC server is called the heartbeat link with the link that is connected between the MSC backup server N+1.In case N master just can take over this fault master and provide professional with the MSC server for BSC with the some faults that taken place in the MSC server, MSC backup server N+1.
But the N+1 backup network can not solve the problem of MSC server redundancy, for example, work hours on daytime, a large amount of mobile device users accumulate in the city center, at this moment, intown telephone traffic is very big, the load capacity that covers the MSC server of coverage, city center like this will be considerably beyond the MSC server that covers the coverage, suburb, and evening, most of mobile device user turns back to the family that is arranged in the suburb, at this moment, the telephone traffic in suburb is very big, and the load capacity that covers the MSC server of coverage, suburb like this will be considerably beyond the MSC server that covers the coverage, city center.This has just caused in different time zones of different laod unbalance problem.
In order to solve the unbalanced problem of this load, MSC server pools backup network has been proposed.MSC server pools backup networking plan is meant forms a resource pool of being responsible for certain zone with some MSC/MSC server nodes, realizes its controlled function to traffic, signaling, and the node in these ponds can link to each other with some BSC/ media gateway-BSC.A BSC shares all MSC servers.That is to say that under MSC server pools backup networking plan, BSC signaling to a plurality of MSC servers can reach each MSC server common service each BSC in the MSC pond in the MSC pond.In case wherein certain MSC server load amount is big especially, extra load capacity will be assigned to other MSC server according to dynamic assignment mechanism.MSC server pools scheme is compared with the N+1 scheme, except back mechanism, also has other advantages, for example, realizes resource-sharing and load balancing effectively, reduces the mobile management number of times, reduces the position renewal and switches the complexity of the reduction network planning etc.
For MSC server pools backup networking plan, two kinds of implementation patterns are arranged now: first kind of pattern, BSC is transferred to the signaling of each the MSC server in the MSC pond by a media gateway; Second kind of pattern, BSC also can connect each media gateway in the MSC pond, signaling is sent to corresponding MSC server, as shown in Figure 2.
Though MSC server pools scheme has certain advantage, but still there is following shortcoming in it: for first kind of pattern, need do very big change to the MSC and the BSC of existing mobile flexible exchanging network during networking: in the MSC pool technology, because a BSC is connected on a plurality of MSC servers, the MSC server wants to distribute the casual user's sign (TMSI) that contains local exchange network resource identifier (NRI) to give the user, when up incoming call, BSC can obtain network resource identifier (NRI) from user's TMSI, find out the MSC server of service according to the NRI that self preserves and the corresponding relation of MSC server, and the message of initial Non-Access Stratum can be distributed to the MSC server of service; If can not obtain user's NRI, BSC can adopt the load balancing algorithm, in the MSC pond, be not in unloading and the signalling point MSC server that can reach and select one,, and the message of initial Non-Access Stratum can be distributed to this service MSC server as user's service MSC server.And media gateway is wanted can the virtual support medium gateway function.
For second kind of pattern, very big change need done during networking on MSC and the media gateway: in the MSC pool technology, because a BSC is connected to a plurality of media gateway, each media gateway is connected to again on a plurality of MSC servers, the MSC server wants to distribute the TMSI that contains local exchange network resource identifier (NRI) to give the user, when up incoming call, media gateway can obtain user ID from initial non-access layer information, and obtains NRI from user ID.Media gateway can find out the MSC server of service according to the NRI that self preserves and the corresponding relation of MSC server, and the message of initial Non-Access Stratum can be distributed to the MSC server of service; If can not obtain user's NRI, media gateway can adopt the load balancing algorithm, in the MSC pond, be not in unloading and the signalling point MSC server that can reach and select one,, and the message of initial Non-Access Stratum can be distributed to this service MSC server as user's service MSC server.And media gateway can the virtual support medium gateway function.Simultaneously, because BSC of this pattern will be connected to a plurality of media gateway, can cause excess configuring time division multiplexing (TDM) resource between BSC and media gateway.
In addition for above-mentioned two kinds of patterns, also there is following common drawback at least: for descending, in case because the MSC server failure causes the customer position information loss of data, this user's position is sought in the paging that just must make the overall situation, will cause very big signaling amount like this.It also is not unusual maturation that the MSC pool technology has many technical schemes, and this brings very big risk to use.

Fig. 2 is the network architecture schematic diagram based on the MSC server pools of mobile soft switch backup networking plan according to prior art, and wherein, BSC connects each media gateway in the MSC server pools, thereby signaling is sent to corresponding MSC server.It will be appreciated by those skilled in the art that the network architecture shown in Figure 2 represented the mobile flexible exchanging network that passes through MSC server pools scheme constructs of the described second kind of pattern of background technology part.Particularly, each BSC can connect each media gateway in the MSC pond, and simultaneously, each media gateway connects each MSC server (for example MSC server 1, MSC server 2) again, thereby makes signaling can be sent to corresponding MSC server.Those skilled in the art are appreciated that at this this and are not described in detail.
Fig. 3 is according to the first embodiment of the present invention, is used to be controlled at the flow chart of the method for the signal transmission between a plurality of BSC and a plurality of MSC server in the MSC of mobile flexible exchanging network media gateway.In the present embodiment, execution in step S11 at first receives up input signal from a plurality of BSC respectively via many groups port, and wherein every group of port comprises one or more ports, and wherein, each BSC inserts this MSC media gateway via one group of port.Those skilled in the art are appreciated that in conjunction with the network architecture of following Fig. 6, in the present embodiment, owing in a media gateway, comprise many group ports, can connect a BSC respectively in every group of port, promptly this BSC inserts this MSC media gateway via one group of port.Therefore, it can send up input signal to the media gateway of correspondence by this group port that it connected for a BSC, and correspondingly, this up input signal is received by the media gateway of correspondence.Enter step S12 then, described up input signal from a plurality of BSC is exchanged processing, and press the mapping relations of port and MSC server, up output signal is sent to a plurality of MSC servers.Be appreciated that when only receiving a up input signal from a BSC, send it to a pairing MSC server after then this signal being handled.In the present embodiment, in the mapping relations of described port and MSC server, every group of only corresponding MSC server of port also is the only corresponding MSC server of a BSC.By step S12, be sent to after described up output signal is processed in the corresponding MSC server, thereby finish purpose of the present invention.It will be appreciated by those skilled in the art that step S12 can finish by the control device that is arranged in the media gateway shown in Figure 6, device 3 for example shown in Figure 7.Further, it will be appreciated by those skilled in the art that and to realize particularly in several ways for example, not being described in detail above-mentioned steps S12 at this by step shown in Figure 4.Then, execution in step S13 again, judge whether to detect one or more MSC servers and particular case occurs? if particular case appears in one or more MSC servers, then enter step S14, will be from being sent to one or more MSC backup servers with the described up output signal that corresponding one or more groups port of each MSC server of particular case occurs; Otherwise this processing procedure finishes, and is handling in (for example receiving the up input signal from BSC once more) process still according to the described step continuation of Fig. 3 processing next time.Those skilled in the art understand, in the present embodiment, the corresponding MSC backup server of described every group of port, therefore, even particular case appears in one or more MSC servers, still the up input signal of script by this MSC server process can be disposed by pairing MSC backup server.
With reference to figure 3, it will be appreciated by those skilled in the art that the described particular case of above-mentioned Fig. 3, Fig. 4 has multiple.For example change in the example at one, the MSC server breaks down and is regarded as a kind of of described " particular case "; And change in the example at another, the MSC server is set to " busy " state and also is regarded as a kind of of described " particular case ".Those skilled in the art are appreciated that at this this and are not described in detail.
It will be appreciated by those skilled in the art that described step S13, S14 also can omit in a variation example embodiment illustrated in fig. 3.In such variation example, need not to carry out the detection of particular case, for example whether do not exist fault to detect to the MSC server; Perhaps, even described up input signal from BSC still is sent to a MSC server (for example finishing the MSC server of MSC backup server similar functions) after treatment can guarantee that a MSC server breaks down by alternate manner the time.This is not a main purpose of the present invention, and should be that those skilled in the art know, and does not repeat them here.
Similarly, those skilled in the art also understand, all carry out above-mentioned steps S13, S14 when not necessarily receiving the up input signal from BSC at every turn, for example change in the example at one, can (promptly after such period expires, carry out the one-time detection operation according to the fixed cycle, influence the function of whole soft mobile telephone exchange network to guarantee the MSC server can not can not get repairing or changing after breaking down for a long time) carry out this two steps, change in example at another and when receiving the report that described up input signal is not normally processed, just carry out these two steps.This is not a main purpose of the present invention, and should be that those skilled in the art know, and does not repeat them here.
Again with reference to the step S14 among above-mentioned Fig. 3, change in the example at one, it can be realized in the following way: at first, set up described corresponding one or more groups port of each MSC server of particular case and the mapping relations of described MSC backup server of occurring, in such variation example, in the mapping relations of described one or more groups port and described MSC backup server, the only corresponding MSC backup server of one group of port (also being a BSC); Then, according to the mapping relations of one or more groups port set up and described MSC backup server, will be sent to described MSC backup server from the up output signal of described one or more groups port.Those skilled in the art understand, in such variation example, described each port that the MSC server of particular case occurs is not established in advance with corresponding (mapping) relation of MSC backup server, and only just sets up provisionally when particular case appears in the MSC server.Further, be appreciated that in such variation example, after the described particular case of MSC server does not exist, then correspondingly can cancel the mapping relations between its port and the MSC backup server.Such variation example provides enough flexibilities for the work of MSC backup server.And change in the example at another, also can set up every group of (individual) port of described each MSC server and the mapping relations of described MSC backup server in advance, and when particular case takes place, use described mapping relations immediately.
Further, Fig. 4 is according to the first embodiment of the present invention, the flow chart of the embodiment of step S12 shown in Figure 3.Particularly, in the present embodiment, described step S12 finishes by two sub-steps.At first execution in step S121 exchanges processing to described up input signal from a plurality of BSC, to generate the up output signal of handling through exchange.Those skilled in the art understand, before signal being sent to corresponding MSC server, corresponding media gateway need exchange processing to the up input signal from a plurality of BSC that receives, and this exchange process is that those skilled in the art know, and does not repeat them here.Then, enter step S122, with the described up output signal through the exchange processing from a plurality of BSC, the mapping relations by described port and MSC server send to a plurality of MSC servers.
More specifically, it will be appreciated by those skilled in the art that described step S122 can realize in several ways.For example, change in the example at one, can be according to the mapping table of the mapping relations that comprise described port and MSC server that prestore, the relevant information (for example, IP address information) of inquiry and every group of corresponding MSC server of port; Then, according to the relevant information of described MSC server, the described up output signal of handling through exchange is sent to corresponding M SC server again.It will be appreciated by those skilled in the art that preferably above-mentioned mapping table is stored in the described media gateway.And change in the example at one, described mapping table also can be stored in the memory space of a special use, and this memory space separates with described media gateway, in in such variation, then can send the mapping relations request to the management devices of the described dedicated memory space of management, and determine described mapping relations according to response result to described request, this does not influence flesh and blood of the present invention, is not described in detail at this.
Fig. 5 is according to a second embodiment of the present invention, is used to be controlled at the flow chart of the method for the downstream signal transmission between a plurality of BSC and a plurality of MSC server in the MSC of mobile flexible exchanging network media gateway.Other is with above-mentioned Fig. 3, Fig. 4 phase region, and flow process shown in Figure 5 is used for downlink transfer information is handled, and Fig. 3, Fig. 4 then are used for the uplink signal is handled.Those skilled in the art will be understood that Fig. 3, the combination of Fig. 5 two parts flow process can intactly be realized the method that is used to be controlled at the signal transmission between a plurality of BSC and a plurality of MSC server in the MSC of mobile flexible exchanging network media gateway provided by the invention, do not repeat them here.
Particularly, according to shown in Figure 5, at first execution in step S21 receives the descending input signal from the MSC server, and this is those skilled in the art's a common practise, is not described in detail at this.Then, described descending input signal is exchanged processing, and descending output signal is sent to corresponding BSC through a corresponding port.Similarly, it will be appreciated by those skilled in the art that described one group of port can comprise one or more ports, this BSC is connected to the MSC media gateway via this group port.Particularly, described descending input signal is exchanged processing, and descending output signal can be accomplished in several ways again through the step that a corresponding port sends to corresponding BSC, for example realize by step S22, S23 in the present embodiment.In step S22, described descending input signal is exchanged processing, generate the descending output signal of handling through exchange, and extract the relevant information of a corresponding port; In step S23, the described descending output signal of handling through exchange is sent to corresponding BSC via a corresponding port.Those skilled in the art understand, in step S22, on the one hand the descending input signal downstream signal of MSC server (promptly from) is handled the downstream signal that has obtained via media gateway output, also obtained the pairing port relevant information of this descending output signal on the other hand, thereby can which port be this descending output signal be sent to so that media gateway is known, this is that those skilled in the art should be able to know, and does not repeat them here.
Fig. 6 is according to a specific embodiment of the present invention, has used the configuration diagram of the mobile flexible exchanging network of the device that is controlled at the signal transmission between a plurality of BSC and a plurality of MSC server provided by the invention.The framework of Fig. 6 is clear to show difference with the prior art of the present invention.Comprising a plurality of MSC servers, for example MSC server 51, MSC server 53 etc. also comprise a MSC backup server 52 simultaneously.Be appreciated that, in the present embodiment, the configuration of described MSC backup server 52 can be identical with MSC server 51 etc. with concrete function, and be its role's difference when networking, certainly, both also can be different, and for example the hardware configuration of MSC backup server 52 is a little less than the configuration of MSC server 51, because its less being used; And change in the example at one, also can not comprise described MSC backup server 52, at this moment, can when breaking down, use a MSC server another MSC server 53 to bear the MSC server role that this breaks down.
In the embodiment shown in fig. 6, each media gateway (being the MSC media gateway), for example media gateway 41～44 is connected to each MSC server, for example MSC server 51, MSC server 53 etc. respectively; Each media gateway also can be connected with this MSC backup server 52 when having MSC backup server 52.Simultaneously, a plurality of BSC are connected to different media gateway respectively, and for example media gateway 41～44.For example be appreciated that with reference to figure 6 BSC1 is connected to one group of port (for example organizing 1) of media gateway 41, BSC2 is connected to another group port (for example organizing 2) of media gateway 41, and BSC3 is connected to the another group of port (for example organizing 3) of media gateway 41; Similarly, BSC1 also is connected to one group of port (for example organizing 1) of media gateway 42, BSC2 also is connected to another group port (for example organizing 2) of media gateway 42, the another group of port (for example organizing 3) that BSC3 also is connected to media gateway 42 again for example, BSC5 is connected to one group of port (for example organizing 1) of media gateway 43, BSC6 is connected to another group port (for example organizing 2) of media gateway 43, by that analogy.Because media gateway 41,42 is connected to MSC server 51,53 respectively, therefore, in fact makes the business of BSC1, BSC2 to be shared jointly by 51,53 two servers of MSC server.It will be appreciated by those skilled in the art that, in actual applications, the One's name is legion of BSC, correspondingly media gateway also exists a plurality of, MSC server and MSC backup server also to exist a plurality of, can be by the network architecture shown in Figure 6 so that the business of BSC can be connected to a plurality of MSC servers even whole MSC server (deciding on concrete connection configuration) by different media gateway, therefore, make the business of a plurality of BSC to be shared by a plurality of MSC servers.
Particularly, can be understood as, by the present invention, a physical media gateway logically is divided into several Virtual Media Gateways (a port set in the above-mentioned media gateway can be corresponded to a Virtual Media Gateway, this port set can comprise one or more groups port, wherein every group of port links to each other with a BSC), these Virtual Media Gateways have been shared the function and the resource of this physical media gateway.Preferably, the only corresponding MSC server (for example call server) of each Virtual Media Gateway, promptly, at up direction, only output to this corresponding MSC server after the respective handling (for example exchange is handled) of input signal from the set of the port in the media gateway through this matchmaker's gateway.Thereby a physical media gateway can utilize the function of a plurality of Virtual Media Gateways to be connected to a plurality of call servers simultaneously.And for BSC, different BSC is connected with a plurality of different Virtual Media Gateways respectively.By this connected mode, for example shown in Figure 6, BSC1, BSC2, BSC3, BSC4 under the coverage that MSC server 51 covers can carry out the signal transmission with different call servers, for example, BSC1 and BSC3 and MSC server 51 carry out the signal transmission, and BSC2 and BSC4 can carry out signal transmission with MSC server 53, thereby a plurality of BSC in zone are (for example BSC1 and BSC2; BSC3 and BSC4) business can bear by a plurality of MSC servers.Therefore, utilize the solution of MSC media gateway provided by the present invention, and the concrete load capacity according to each coverage suitably is provided with (as shown in Figure 6) when networking, can have solved the problem of the load balancing of MSC server preferably.
Further, the uplink information of BSC can be sent to a MSC server by every group of port in the media gateway.Preferably, BSC1 is connected with the 1st group of port of media gateway 41 and the 2nd group of port of media gateway 42 respectively, and wherein, the 1st group of port of media gateway 41 and the 2nd group of port of media gateway 42 all are connected with MSC server 51 among Fig. 6.
BSC can link to each other with a MSC server via a plurality of media gateway (being different links), in this case, can decide a particular moment and should carry out transfer of data via which link by signaling protocol MTP3 between this BSC and the media gateway.Concrete, as shown in Figure 6, BSC1 can determine that by signaling protocol MTP3 signaling message (uplink information) on it is the 1st a group of port by media gateway 41 or the 2nd group of port of media gateway 42 sends to MSC server 51 with media gateway 41 and media gateway 42, in case (for example selected certain link, the 1st group of port of media gateway 41 or the 2nd group of port of media gateway 42), BSC1 just communicates by this link and MSC server 51.Preferably, sometime, if 1st group port and the MSC server 51 of BSC1 by media gateway 41 communicates, so, in the next moment, BSC1 will communicate by the 2nd group of port and the MSC server 51 of media gateway 42.
Again particularly, the mode of the uplink signal transmissions between a plurality of BSC and a plurality of MSC server is as follows: the 1st group of port of media gateway 41 and the 2nd group of port receive respectively from the upward signal of BSC1 and BSC3 (wherein, the 1st group of port and the 2nd group of port belong to first port set corresponding to the first virtual service gateway, it is corresponding with MSC server 51) then 41 pairs of up input signals of media gateway from BSC1 and BSC3 exchange processing, and, make this up output signal of handling through exchange send to MSC server 51 according to the mapping relations of this port set with the MSC server.Similar, preferably, the 3rd port of media gateway 41 and the 4th group of port are (wherein, the 3rd group of port and the 4th group of port belong to second port set corresponding to second Virtual Media Gateway, it is corresponding with MSC server 53) receive upward signal respectively from BSC2 and BSC4,41 pairs of up input signals from BSC2 and BSC4 of media gateway exchange processing then, according to the mapping relations of port and MSC server, make this upward signal of handling through exchange send to MSC server 53.As seen, (wherein, the set of first port comprises: the 1st group of port and the 2nd group of port by two different ports set by 41 pairs of same media gateway; Second port set comprises: the 3rd group of port and the 4th group of port) the up input signal from different B SC of input handles respectively, in such preferred embodiment, be equivalent to the function that a media gateway 41 has realized a plurality of media gateway, therefore, it can be interpreted as that a media gateway 41 has comprised a plurality of Virtual Media Gateways.
Further, downstream signal transmission manner between a plurality of BSC and a plurality of MSC server is as follows: the 1st sets of ports splice grafting of media gateway 41 is received the descending input signal from MSC server 51,41 pairs of described descending input signals of media gateway exchange processing then, generate descending output signal, and by wherein extracting the indication information be used to indicate corresponding one a group of port (for example above-mentioned the 1st group of port or the 2nd group of port) or a concrete port, and the descending output signal of handling through exchange will be sent to corresponding BSC (being BSC1 or BSC3 accordingly) through indicated port (for example above-mentioned the 1st group of port or the 2nd group of port).
Therefore, those skilled in the art understand, by the described network architecture of Fig. 6, under the situation of not changing MSC server, BSC, by control to the MSC media gateway, just can realize the effect that the business of a plurality of BSC can be finished jointly by a plurality of MSC servers, be equivalent to share the business of script by a plurality of BSC of a MSC server admin by a plurality of MSC servers, in other words, control device provided by the invention and control method have realized the effect with the networking plan equivalence of above-mentioned MSC server pools at least.For example, suppose that MSC server 51 shown in Figure 6 is positioned at the urban district, MSC server 53 is positioned at the suburb, in the operating time (for example Monday is to the 8:00 to 20:00 on Friday), it is very big to be positioned at the BSC traffic carrying capacity that the MSC server 51 in urban district managed, at this moment, it is correspondingly few exactly to be positioned at the BSC traffic carrying capacity that the MSC server 53 in suburb managed, therefore, the load that can share MSC server 51 by the MSC server 53 that is positioned at the suburb, thereby realize sharing of resource, the more important thing is can be quick, finish the request that BSC sends efficiently, be unlikely to cause service can't in time be provided because 51 loads of MSC server are overweight.
