Description
Technical field
The present invention relates to mobile communication system, more specifically refer to a kind of by mobile communication operating system realization attaching position register redundant disaster method.
Background technology
Along with mobile subscriber's the quick increase and the continuous development of mechanics of communication, the single-machine capacity of attaching position register (HLR) is hundreds of thousands even more often.Since home location register stores mobile subscriber's CAMEL-Subscription-Information; in case shut down owing to cause the attaching position register chromic trouble such as unpredictable reasons such as outage, fire, earthquake, thunderbolts; all contracted users' mobile service will be interrupted; so, provide long-range superfluous calamity to become the task of top priority to attaching position register.
The superfluous calamity of attaching position register comprises the content of two aspects, one is the superfluous calamity of data that is used for backing up user data merely, another one is a professional superfluous calamity on this basis, when promptly the master breaks down with attaching position register, superfluous calamity attaching position register can be taken over its business, guarantees the uninterrupted of call business to greatest extent.
According to whether being under the jurisdiction of same manufacturer, superfluous calamity can be further divided into compatible superfluous calamity and the superfluous calamity of incompatibility by backup attaching position register, superfluous calamity center attaching position register.Because current domestic attaching position register supply of equipment producer is many, different attaching position registers are all inequality to storage format, the processing mode of user data, so the compatible scheme scope of application is more extensive.
Each equipment supplier has realized the superfluous calamity of local data of attaching position register at present substantially, promptly realize the schedule backup of user data by magnetic tape station or disk, but professional superfluous calamity is not widely used as yet.
The superfluous calamity of teledata is divided into two kinds on topological structure, a kind of is the superfluous calamity scheme of 1+1, and a kind of is the N+1 scheme.Clearer and more definite scheme has 1+1 expansion MAP (MAP) protocol signaling scheme and the synchronous subscription data scheme of N+1 at present, is introduced respectively below:
1+1 expansion MAP protocol signaling solution (is seen Fig. 1, STP is a Signalling Transfer Point among Fig. 1): generally be the mutual backup between two attaching position registers (HLR), its core content is to carry all kinds of operational orders by the signalling system No.7 of expanding, and realizes the consistency of data.At first, each attaching position register is not only preserved home subscriber information, also keeps the user profile of Another Place To Fall location register simultaneously, and these user profile use " main/attached " sign position to identify respectively in attaching position register inside.Each attaching position register is when sending to the standard signaling (operational order) of oneself according to normal flow reception, processing, the MAP protocol message that the user data that also this signaling (operational order) will be caused changes by expansion is notified to corresponding backup attaching position register, carry out data synchronization updating by backup attaching position register, thereby realize data sync.The MAP protocol message of expansion comprises modification, newly-increased and deletion action.
The synchronous subscription data scheme of N+1: simultaneously a plurality of attaching position registers are carried out superfluous calamity by an attaching position register, claim that superfluous calamity attaching position register is superfluous calamity center this moment.Its core content is all CAMEL-Subscription-Information of user that CAMEL-Subscription-Information changes to be outputed in the text with the agreement form with attaching position register by main, submits to superfluous calamity center by special line and loaded, thus the unanimity of realization both sides data.
Though the network configuration of above-mentioned 1+1 expansion MAP protocol signaling solution is more succinct, has following problem:
1) cost height: apparent, for a large amount of attaching position registers of online operation respectively are equipped with a cover disaster tolerant system, cost is very high, especially under the very little situation of attaching position register probability of malfunction; Even adopt the 1+1 superfluous calamity mode that circulates, though need not to increase the quantity of attaching position register, owing to require each attaching position register all will back up the user data of other attaching position register, so the upgrade cost of equipment is still very high;
2) technical difficulty is bigger, implementation cycle is long: the attaching position register in this scheme not only will be given the other side's attaching position register with the change notification of self attaching position register user data according to the standard signaling method, but also to receive, handle the user data synchronization message that the other side sends, the change demand of attaching position register software systems is bigger;
3) difficult management owing to held other attaching position register user data in the attaching position register, makes existing management mode cause difficulty;
4) clear and definite solution is not proposed compatibility, especially to the backup problem of the self-defining characteristic service data of each manufacturer.
5) existing signaling system there is bigger impact: owing to daily mass data is transmitted by No.7 nation-wide Network synchronously fully, so signaling traffic load is multiplied.
Though and the synchronous subscription data scheme of N+1 has been avoided the defective of the superfluous calamity scheme of 1+1, but still there is following problem:
1) performance to existing attaching position register has very big influence: because each of corresponding CAMEL-Subscription-Information changes, the master must be exported all CAMEL-Subscription-Information of this user with attaching position register; Loaded down with trivial details cancellation, account-opening also will be done accordingly in superfluous calamity center, and the MAP protocol message disposal ability of system is had very big influence;
2) transformation to existing net equipment is bigger, scheme can be implemented lower: exported with attaching position register by main because all user data change all, so in order to support superfluous calamity characteristic, survey is upgraded, transferred to requirement to all masters with attaching position register, quantities is huge, and exploitativeness is lower.
