For the ease of setting forth the present invention, be described in further detail below with reference to the enforcement of drawings and the specific embodiments to technical solution of the present invention.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Fig. 2 shows the disaster tolerance networking schematic diagram of the identity position separation network of the embodiment of the present invention.As shown in Figure 2, having 3 ASN in figure, is ASN1, ASN2, ASN3 respectively, and these 3 ASN form an ASN service area (Service Area), is any wireless network services jointly.In order to realize disaster tolerance function, this RNC of RNC(does not refer in particular to the RNC in UMTS network) and each ASN between adopt IP networking, to ensure that RNC and each ASN interconnects.
Meanwhile, in order to realize the disaster tolerance between ASN, the present invention adopts N+1 disaster tolerance mode (1+1 can think the special circumstances of N+1).Wherein, the implication of N+1 disaster tolerance mode is: comprise an ASN for subsequent use in ASN service area, be N number of ASN is under normal circumstances mobile network service, in the some ASN in N number of ASN go wrong, then by new service access on ASN for subsequent use, continue as Terminal for service.
In above-mentioned N+1, the configuration capacity/performance of each ASN can be equal, also can be unequal.If the maximum traffic capacity of each ASN is equal, so suppose that the whole network user capacity is 1,200,000, provide service by 3+1=4 ASN, the capacity of so each ASN is exactly 1,200,000/3=40 general-purpose family.When normal work, provide service by 3 ASN, when 1 ASN goes wrong, ASN for subsequent use will enable.
If the maximum traffic capacity of each ASN is not equal, the capacity so as that ASN of backup identity needs to be equal with that ASN of heap(ed) capacity.Suppose that the whole network user capacity is 1,200,000, provide service by 3+1=4 ASN, when normal work, the capacity of each ASN is ASN1 capacity=300,000, ASN2 capacity=400,000, ASN3 capacity=500,000.Capacity as that ASN for subsequent use is at least 500,000, and when preventing ASN3 from ging wrong, ASN for subsequent use can meet the capacity requirement of ASN3.
In the wireless network, in order to maintain secrecy, after service access success, temporary mark (Temporary Identity can be adopted on eating dishes without rice or wine, be called for short TID) represent different users, TID, when user accesses and successfully does miscellaneous service, remains unchanged, and when user accesses at every turn, its TID can change.TID is distributed by ASN, in order to ensure, when user is linked into and does business after ASN, to ensure or provide service by same ASN for this user, requiring when distribution T ID, include the information of ASN in TID.After user on wireless network accesses ASN, ASN is search corresponding RID by user AID, then data message is sent to target ASN, target ASN re-sends to the user that target AID identifies.
In the present invention, in order to realize the load sharing between ASN, can comprise number segment information of part AID in TID, number segment information of this AID can be through the information after encryption.RNC, when terminal accesses, can select ASN according to AID, and after business success, RNC also selects ASN according to the AID information in TID.
Particularly, the corresponding relation of each ASN and AID section can be configured on RNC; Further, can also according to the volume of business of ASN, the AID segment limit that configuration and its volume of business match.If the Capacity Ratio of ASN is lower, then the manageable number of users of ASN is few, if the capacity of ASN is large, so the manageable number of users of ASN is just many.Such as: suppose 5+1 ASN(ASN1, ASN2, ASN3, ASN4, ASN5) form a service area, the capacity ratio of these 5 ASN is ASN1:ASN2:ASN3:ASN4:ASN5=1:1:2:2:2 respectively; And the capacity of ASN6 for subsequent use is equal with the capacity of ASN3/ASN4/ASN5.In the case, then the scope of AID can be equally divided into 8 equal portions, access ASN1-ASN5 respectively.
As shown in table 1 below, when terminal initial accesses, according to number Duan Laiwei of AID, it selects the ASN of access to RNC:
The mapping table of table 1 AID section and ASN
And in user's access procedure, ASN can give mobile subscriber distribution T ID, can comprise the information of AID section in the TID of distribution, its concrete distribution method is as shown in table 2 below:
The TID that table 2 ASN distributes
User accesses successfully, in a mobile network use TID is carried out identifying user.
Meanwhile, also need to set up service condition testing mechanism between RNC and ASN.Such as, RNC periodically sends detect-message to ASN, requires that ASN returns its operating state.If the work state information that ASN returns shows the message that its abnormal state or RNC do not receive ASN and return after sending state-detection message within the time determined; then illustrate that this ASN can not normally work, RNC is upper carries out disaster tolerance process by needs to ASN.Now, the business on this ASN is interrupted, and terminal use will access again.
RNC is after detecting that ASN is abnormal, and by the mapping table of the AID section on amendment RNC with ASN, RNC needs notice ASN6 simultaneously, makes ASN6 distribute correct TID.Suppose that ASN3 has exited service, so, provide service as ASN6 for subsequent use by replacement ASN3.Now, amended form is as shown in table 3 below:
The mapping table of the amended AID section of table 3 and ASN
Now, ASN is that the information of the AID section comprised in the TID of terminal distribution is as shown in table 4 below:
The TID that after table 4 disaster tolerance, ASN distributes
After this, ASN3 recover normal after, can again using ASN3 as ASN for subsequent use, and without the need to business is switched back on ASN3.
Be described further below with reference to the enforcement of embody rule example to technical solution of the present invention.
As shown in Figure 3, set up an ASN service area, when this service area is by multiple ASN(such as 5+1 networking, ASN1, ASN2, ASN3, ASN4, ASN5 are host apparatus under normal circumstances, and ASN6 is for subsequent use) composition, composition N+1 disaster tolerance mode.The concrete handling process of this application example is described below:
Step 1, initial networking, each access control equipment (in this example for RNC) is IP networking with each ASN in ASN service area, can intercommunication;
Step 2, each RNC is configured the mapping table of AID section and ASN;
Step 3, when user accesses first time, RNC selects corresponding ASN according to a number segment information of user AID, and namely according to the mapping table of configuration on RNC, the ASN(selecting number section correspondence belonging to user AID is such as ASN3); In the process of access, ASN3 gives this user distribution T ID, comprises the AID information (partial information) of this user in TID;
Step 4, this user accesses successfully, when carrying out business, RNC only sees TID, and RNC takes out AID information from TID, with ensure to make this user be linked into before access successful ASN(and ASN3) on;
Step 5, user terminal carries out normal business;
Step 6, when RNC detects that ASN1 appearance exits service extremely, the business of this user terminal will have short interruptions;
Step 7, this user terminal accesses automatically again, and RNC is by ASN6 for subsequent use for selection for this mobile subscriber provides business, and now, in RNC and ASN service area, the interconnected situation of each ASN as shown in Figure 4.
Step 8, ASN3 recover normal after using as new ASN for subsequent use.
