Technical field
The present invention relates to mobile communication, particularly mobile flexible exchanging network.
Background technology
The running that the mobile communication technology development makes the mobile subscriber pass through different network elements in the core net realizes multiple business such as call business, short message service, prepayment service.
At PLMN (Public Land Mobile Network, Public Land Mobile Nerwork) in the network, the mobile subscriber is in certain lane place, the lane place belongs to certain RNC (RadioNetwork Controller, the wireless access net controller) administration, and RNC is administered by certain MSC Server (Mobile Switching Centre Server, Mobile Switching Center Server).When the mobile subscriber need carry out needing at first to insert core net by Access Network when certain is professional, by the traffic signaling flow processs such as MSC Server network element control calling in the core net, finish the desired business of user then.
In present network was realized, each network element all was independent unique, the user that it is managed and the function of realization, other network element in the network can not substitute, in case certain network element generation catastrophe failure, short-term can not be recovered, and just can cause large quantities of users for a long time can't access network.
Summary of the invention
The object of the invention: be in order to solve in the present network realization, each network element all is independent unique, the user that it is managed and the function of realization, other network element in the network can not substitute, in case certain network element generation catastrophe failure, short-term can not be recovered, and causes the problem that large quantities of users for a long time can't access network.
For achieving the above object, the present invention proposes the disaster recovery method of mobile flexible exchanging network, it is characterized in that, may further comprise the steps:
One, each RNC by MGW (Media Gate Way, media gateway) with two or more (not comprising two) MSC Server be connected;
Two, determine that the master uses the corresponding relation between MSC Server and other the standby MSC Server, comprises following four kinds of schemes:
(1) the active and standby scheme of MSC Server 1+1: the MSC Server that links to each other with RNC comprises two, a main usefulness, and another is standby, and is standby and main with corresponding one by one.
(2) the active and standby scheme of MSC Server N+1: the main MSC of the using Server that each RNC is corresponding with each respectively links to each other, and all main standby Server with MSC Server are the same MSC Server that is connected with all RNC.
(3) the load sharing scheme of MSC Server: the MSC Server that links to each other with RNC comprises two, a main usefulness, and another is standby, is again the main MSC Server that uses of other RNC for standby MSC Server.
(4) RNC selects MSC Server scheme: the MSC Server that links to each other with RNC comprises more than two and two and (does not comprise two) wherein have only one to be to lead to use MSC Server, and other is standby.The master who is other RNC for standby MSC Server again uses MSCServer.
Three, main with the mutual switching between MSC Server and the standby MSC Server:
(1) for the active and standby scheme of MSC Server 1+1, when the master used MSC Server operate as normal, standby MSC Server did not work.When the master delayed machine with MSC Server after, standby MSC Server changed main user with MSC Server adapter RNC into, and former master is changed standby MSC Server into after recovering normally with MSCServer.
(2) for the active and standby scheme of MSC Server N+1, when the master used MSC Server operate as normal, standby MSC Server did not work.Behind the main machine of delaying with MSC Server, the user of former RNC is taken over by standby MSC Server, and after the main MSC of using Server recovered normally, all users were switched back the main MSC Server that uses again.
(3) for the load sharing scheme of MSC Server, when the main MSC of the using Server that links to each other with RNC is working properly, all are all handled with MSCServer by main by the user that this RNC inserts, when the master is unusual with MSC Server, MGW takes over control by standby MSC Server, all are handled by standby MSC Server by the user that this RNC inserts, and recover just often the main MSC Server that uses of user's switchback with MSC Server when main.Main is independent network element with MSCServer and standby MSC Server, active and standby each other each other, and standby MSCServer is that the main of other RNC used MSC Server, operate as normal in network simultaneously.
(4) select MSC Server scheme for RNC, when the main MSCServer of using that links to each other with RNC is working properly, all are all handled with MSC Server by main by the user that this RNC inserts, with MSC Server when unusual, RNC selects one or load sharing to select a plurality of standby MSC Server to handle the user of this RNC access from standby MSC Server when main.Recover just often the main MSC Server that uses of user's switchback with MSC Server when main.
Adopt the disaster recovery method of mobile flexible exchanging network of the present invention, take place when unusual at MSC Server, other MSC Server (the standby MSC Server of fault MSC Server) can take over all users, and can successfully handle all business of this type of user.When former fault MSC Server recovered operate as normal, user's business also can level and smooth switching be returned Anchor MSC Server.So that when MSC Server significant trouble occurs and is difficult to recover for the moment, business that can its leading subscriber of normal process reaches the purpose of disaster tolerance.

Embodiment
Fig. 1 is the flow chart of the disaster recovery method of mobile flexible exchanging network of the present invention.Each RNC by MGW with two or more (not comprising two) MSC Server be connected;
Determine main with the corresponding relation between MSC Server and other the standby MSC Server, comprise four kinds of schemes: the active and standby scheme of MSC Server 1+1, the MSC Server that links to each other with RNC comprises two, main using, another is standby, and is standby and main with corresponding one by one; The active and standby scheme of MSC ServerN+1, the MSC Server that links to each other with RNC comprises two, wherein has only one to be that the master uses MSC Server, and one is standby, and all main standby Server with MSC Server are same MSC Server; The load sharing scheme of MSC Server, the MSC Server that links to each other with RNC comprises two, a main usefulness, another is standby, is again the main MSC Server that uses of other RNC for standby MSCServer; RNC selects MSC Server scheme: the MSC Server that links to each other with RNC comprises more than two and two and (does not comprise two) wherein have only one to be to lead to use MSC Server, and other is standby.Again the main MSC Server that uses of other RNC for standby MSCServer.
Main with the mutual switching between MSC Server and the standby MSC Server: for the active and standby scheme of MSCServer 1+1, when the master used MSC Server operate as normal, standby MSC Server did not work.Behind the main machine of delaying with MSC Server, standby MSC Server changes the user that the main MSC of using Server takes over RNC into, and former master is changed standby MSC Server into after recovering normally with MSC Server; For the active and standby scheme of MSC Server N+1, when the master used MSC Server operate as normal, standby MSC Server did not work.Behind the main machine of delaying with MSC Server, the user of former RNC is taken over by standby MSC Server, and after the main MSC of using Server recovered normally, all users were switched back the main MSC Server that uses again; Load sharing scheme for MSC Server, when the main MSC of the using Server that links to each other with RNC is working properly, all are all handled with MSC Server by main by the user that this RNC inserts, when the master is unusual with MSC Server, MGW takes over control by standby MSC Server, all are handled by standby MSC Server by the user that this RNC inserts, and recover just often the main MSC Server that uses of user's switchback with MSC Server when main.Main is independent network element with MSC Server and standby MSC Server, active and standby each other each other, and standby MSC Server is that the main of other RNC used MSCServer, operate as normal in network simultaneously; Select MSC Server scheme for RNC, when the main MSC of the using Server that links to each other with RNC is working properly, all are all handled with MSC Server by main by the user that this RNC inserts, with MSC Server when unusual, RNC selects one or load sharing to select a plurality of standby MSC Server to handle the user of this RNC access from standby MSC Server when main.Recover just often the main MSC Server that uses of user's switchback with MSC Server when main.
Fig. 2 is a MSC Server 1+1 main preparation system structure chart of the present invention.When the MSCServer electrifying startup, be standby with status modifier earlier, after waiting to receive the registration message of MGW, again state is changed into main using.When main with the MSC Server abnormal conditions such as machine of delaying, its MGW that controls re-registers to standby MSC Server, after MSC Server received the registration message of MGW, revising MSC Server state was main usefulness, and sent Reset (resetting) message informing RNC release resource.
In this kind scheme, position renewal and access procedure are unaffected, and be consistent with normal processes.Need do special processing for the called subscriber.After HLR (Home Location Register, attaching position register) receives the inquiry route requests, to MSC Server request roaming number.When message goes up routing at the STP (Signal Transfer Point Signalling Transfer Point) with MSC server direct connection,, then select alternate routing, issue standby MSC Server if main obstructed with the Server link.After MSC Server receives the roaming number request message, carry out Restore (recovery) process, obtain user's data, and Provide Roaming Number to HLR.
After the former main MSC of using Server recovers normally, re-power startup, be standby with status modifier, change standby MSC Server into, quit work.
Former main with change into new standby after, position renewal and go out to exhale unaffected.For VLR number among the HLR still is former main called subscriber with VLR number, can adopt the method for upgrading HLR to recover called ability.Receive the inquiry route requests of GMSC (Gateway MSC, mobile switching centre's gateway) as HLR after, Xiang Yuanzhu asks roaming number with MSC Server.After former master receives message with Server, check and find to lay oneself open to stand-by state that then return maperror (MAP mistake) message to HLR, failure Provides Roaming Number.Send position updating request to HLR then, carry new master in the message and use VLR number.After HLR receives message, can upgrade VLR (the Visitor Location Register among the HLR, the shift position register) number is the new main VLR number of using, and sends Cancel Location (position deletion) message and insert subscriber data message for simultaneously former master with VLR.No matter whether HLR upgrades successful, the VLR number among the HLR has been revised as new master uses VLR number.The former main VLR of using initiatively calls the user profile that the database deletion is preserved after upgrading the end of HLR process.
Fig. 3 is a MSC Server N+1 main preparation system structure chart of the present invention.When main with the MSC Server abnormal conditions such as machine of delaying, its MGW that controls re-registers to standby MSC Server, after MSC Server received the registration message of MGW, the state of revising standby RNC, LAI was main usefulness, and sent Reset message informing RNC release resource.
When the user when this RNC inserts, SG (singnal gateway, SGW) is transmitted to MSC Server and handles.After MSC Server receives message, at first check whether this RNC belongs to this MSC Server administration in state RNC tabulation, if find then allow the user from this RNC access main.In tabulating with state LAI, the master checks whether LAI is familiar with then.If find, then think to allow the user to insert.
If the user ID of being with is TMSI (Temporary Mobile SubscriberIdentity in the signaling, casual user's sign), and the state of MSC Server is a stand-by state, if can find the user according to TMSI, for avoiding this user may be the identical different user situation of TMSI, can take following three kinds of methods: one, must be to the desirable IMSI of MS (International Mobile Subscriber Identity, international subscriber identity);
Two, must carry out authentication, if failed authentication need re-authenticate behind the desirable IMSI of MS.
Three, by the method for salary distribution of control TMSI, (distribute 0xxxxxxxxxxxxxx as main with MSC Server, standby MSC Server distributes 1xxxxxxxxxxxxxxx to determine whether wanting IMSI to MS; Just can know by the TMSI sign whether this is that oneself distributes like this, if, then handle, otherwise initiate the user ID process according to normal flow, want IMSI to MS).When among the standby MSC Server during user data of no use, how obtaining user data can have following two kinds of schemes: one, carry out the position updating process of HLR, the VLR number that upgrades among the HLR is standby VLR number, thereby obtains user data.If two VLR find that the state of MSC Server is a stand-by state, then enable position renewal process not starts the Restore process, obtains user data, and the VLR number among the HLR remains unchanged.
After HLR receives the inquiry route requests, to MSC Server (VLR) request roaming number.Message with the STP of MSC server direct connection on during routing, if main obstructed, then select alternate routing with the Server link, issue standby MSC Server.
After MSC Server receives the roaming number request message, carry out the Restore process to HLR, the acquisition user's data also Provides Roaming Number.MSC Server calling user only is the RNC transmission beep-page message of main usefulness to the RNC state.
Main with after the MSC server recovery normally, the MGW disconnection is connected with standby MSC Server's, re-registers to main MSC Server.After standby MSC Server received the disconnection message of MGW, the state of revising standby RNC, LAI was standby.Main with after the MSC Server recovery normally, to RNC transmission Reset message, notice RNC discharges resource.The main MSC Server that uses of user's switchback.
For the processing that the position is upgraded or gone out to exhale, consistent with standby MSC Server, for avoiding the identical different user situation of TMSI occurring, also need to force authentication.
For the called subscriber, if the position is upgraded or select not upgrade HLR during caller, start the Restore process, the then professional main MSC Server that uses of switchback automatically, called flow is unaffected.If select to upgrade HLR, be the called subscriber of standby VLR number for VLR number among the HLR, consider to adopt the method for upgrading HLR to recover called ability.Receive the inquiry route requests of GMSC as HLR after, to standby MSC Server request roaming number.After standby MSCServer receives message, find user profile after, check whether user's LAI state is stand-by state, if, then return map error message to HLR, failure Provides Roaming Number.Send position updating request to HLR then, carry the main VLR number of using in the message.After HLR received message, the VLR number that can upgrade among the HLR was the main VLR number of using, and sent Cancel Location message and insertion subscriber data message for simultaneously standby VLR.No matter whether HLR upgrades successful, the VLR number among the HLR has been revised as the main VLR number of using.Standby VLR initiatively calls the user profile that the database deletion is preserved after upgrading the end of HLR process.
Fig. 4 is a MSC Server load sharing system structure chart of the present invention.When main with the MSC Server abnormal conditions such as machine of delaying, its MGW that controls re-registers to standby MSC Server, after MSC Server receives the registration message of MGW, revise standby RNC, LAI (Location Area Identity, Location Area Identification) state is the standby main usefulness that transfers to, and sends Reset message informing RNC release resource.
When the user when this RNC inserts, SG is transmitted to MSC Server and handles.After MSC Server receives message, call database, check whether this RNC belong to this MSC Server administration with state RNC tabulation and standby alternation of hosts in state RNC tabulation main, tabulate with state LAI and standby alternation of hosts searches tabulating with state LAI if find then allow the user to insert then from the master from this RNC.If find, think to allow the user to insert.
If the user ID of being with is TMSI in the signaling, and the state of MSC Server is stand-by state, if can find the user according to TMSI, may be the identical different user situation of TMSI for avoiding this user, and processing can be with reference to the processing of N+1 backup.
When among the standby MSC Server during user data of no use, how obtaining user data can be with reference to the processing of N+1 backup.
After HLR receives the inquiry route requests, to MSC Server request roaming number.Message with the STP of MSC Server direct connection on during routing, if main obstructed, then select alternate routing with the Server link, issue standby MSC Server.
After MSC Server receives the roaming number request message, carry out the Restore process, obtain user's data to HLR.And Provide Roaming Number.
MSC Server calling user is that the RNC that primary and backup alternation of hosts uses sends beep-page message to the RNC state only.
Main with after the MSC server recovery normally, the MGW disconnection is connected with standby MSC Server's, re-registers to main MSC Server.After standby MSC Server received the disconnection message of MGW, the state of revising standby RNC, LAI was standby.Main with after the MSC Server recovery normally, to RNC transmission Reset message, notice RNC discharges resource.The main MSC Server that uses of user's switchback.
For the processing that the position is upgraded or gone out to exhale, consistent with standby MSC Server.Called processing can be with reference to the processing of N+1 backup.
Fig. 5 is that RNC of the present invention selects MSC Server scheme system construction drawing.RNC selects MSC Server mode can take following three kinds of methods.Method one is according to all users of the preferred standby MSC Server processing RNC of priority; Method two according to LAI under the user, selects different MSC Server to handle the different user of RNC; Method three according to the principle of taking turn, selects different MSC Server to handle the different user of RNC.Behind the main machine of delaying with MSC Server of RNC, RNC interrupts with MSC Server link fully with main, and signalling point is unreachable.
Mode is a method one if RNC selects MSC Server, and then RNC selects the highest MSC Server of priority of (signalling point can reach) working properly from standby MSC Server tabulation, its state is become standby alternation of hosts use state.RNC sends Reset message for the new MSC Server that takes over, and after MSC Server receives message, changes RNC, LAI state into standby alternation of hosts and uses.When the user inserted from RNC, selection mode was that the MSC Server that standby alternation of hosts uses handles all users.
Mode is a method two if RNC selects MSC Server, then RNC selects MSC Server working properly from standby MSC Server tabulation, the LAI of RNC administration is distributed to these Server, the corresponding relation of record LAI and Server, and send Reset message, notify these MSC Server to change RNC, LAI state into standby alternation of hosts and use.When the user inserts,, select MSC Server according to the mapping table of LAI and Server.
Mode is a method three if RNC selects MSC Server, sends Reset message, notifies all standby MSC Server to change RNC, LAI state into standby alternation of hosts and uses.When the user inserts from RNC, select concrete MSC Server to come process user according to the taking turn principle.
The realization of position renewal or access procedure is identical with MSC Server load sharing scheme.Select to upgrade the information among the HLR.
After HLR receives the inquiry route requests, to MSC Server (VLR) request roaming number.Message with the STP of MSC server direct connection on during routing, if main obstructed, then select alternate routing with the Server link, issue standby MSC Server.
After MSC Server receives the roaming number request message, carry out the Restore process, obtain user's data to HLR.And Provide Roaming Number.
MSC Server calling user is that the RNC that primary and backup alternation of hosts uses sends beep-page message to the RNC state only.
After RNC receives beep-page message, need the paged user of record and send the MSCServer sign of paging, so that, select the MSC Server that sends paging to handle receiving that page response or position upgrade or go out to call for when asking.
Main with MSC Server recover normal after, send Reset message informing RNC, MSCServer recovers operate as normal, after RNC receives Reset message, is standby with standby alternation of hosts with the status modifier of the MSC Server of state.After this user who inserts by this RNC is still normally main with MSC Server processing by it.
For the processing that the position is upgraded or gone out to call out, consistent with standby MSC Server.
For VLR number among the HLR has been the called subscriber of standby VLR number, because can't obtaining the master, standby MSC Server whether recovers normal with MSC Server, so can't revise the RNC that standby alternation of hosts uses, the state of LAI, so considering this type of user is still temporarily handled by standby MSC Server, up to this type of user carries out the position renewal by RNC after, revised the VLR number among the HLR.Standby MSC Server sends beep-page message, after RNC receives, if from standby MSC Server's, then write down the MSC Server sign of paged user and transmission paging, so that, select the MSC Server that sends paging to handle receiving that page response or position upgrade or go out to call for when asking.
When this type of user carried out the normal position renewal by RNC, the VLR number that can revise among the HLR was that the master uses VLR number, HLR can send Cancel Location message to standby MSCServer, standby MSC Server deletion this moment user data.Can mainly be that state is the LAI of standby alternation of hosts with state with the user among the VLR according to constituting a chained list according to LAI.After standby MSC Server deletion LAI state is the user that uses of standby alternation of hosts, check this tabulation, if chained list be a sky, then the status modifier with this LAI is standby.The state of all LAI all becomes stand-by state by standby alternation of hosts with state under RNC, is standby with the status modifier of this RNC.
