For the ease of setting forth the present invention, below will combine accompanying drawing and specific embodiment that the enforcement of technical scheme of the present invention is described in further detail.Need to prove that under the situation of not conflicting, embodiment among the application and the characteristic among the embodiment be combination in any each other.
Fig. 2 shows the disaster tolerance networking sketch map of the identity locator separation network of the embodiment of the invention.As shown in Figure 2, have 3 ASN among the figure, be respectively ASN1, ASN2, ASN3, these 3 ASN form an ASN service area (Service Area), are any wireless network services jointly.In order to realize the disaster tolerance function, adopt the IP networking between RNC (this RNC does not refer in particular to the RNC in the UMTS network) and each ASN, all interconnect to guarantee RNC and each ASN.
Simultaneously, in order to realize the disaster tolerance between the 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: comprising a subsequent use ASN in the ASN service area, is that N ASN is mobile network's service under the normal condition, when the some ASN in N ASN go wrong; Then with new service access to subsequent use ASN, continue as the terminal service be provided.
Configuration capacity/performance of each ASN can equate among the above-mentioned N+1, also can be unequal.If the maximum traffic capacity of each ASN equates, suppose that so the whole network user capacity is 1,200,000, by 3+1=4 ASN service is provided, the capacity of each ASN is exactly 1,200,000/3=40 general-purpose family so.In operate as normal, by 3 ASN service is provided, when 1 ASN goes wrong, subsequent use ASN will launch.
If the maximum traffic capacity of each ASN does not equate that the capacity as that ASN that backs up identity need be to equate with that ASN of heap(ed) capacity so.Suppose that the whole network user capacity is 1,200,000, by 3+1=4 ASN service is provided, the capacity of each ASN is ASN1 capacity=300,000 in operate as normal, ASN2 capacity=400,000, ASN3 capacity=500,000.Capacity as that subsequent use ASN is 500,000 at least, and when preventing that ASN3 from ging wrong, subsequent use ASN can satisfy the capacity requirement of ASN3.
In wireless network, in order to maintain secrecy, after the service access success; Can adopt temporary mark (Temporary Identity on eating dishes without rice or wine; Be called for short TID) represent different users, TID the user insert successfully do miscellaneous service in, remain unchanged; And in the each access of user, its TID can change.TID is distributed by ASN, for guarantee the user be linked into ASN do later on professional in, guarantee or come service to be provided for this user by same ASN, require in distribution T ID, to include the information of ASN among the TID.User on the wireless network inserts after the ASN, on ASN is to search corresponding RID through user AID, sends to target ASN to data message then, and target ASN re-sends to the user that target AID is identified.
Among the present invention, in order to realize the load sharing between the ASN, in TID, can comprise number segment information of part A ID, number segment information of this AID can be through the information after the encryption.When RNC inserts at the terminal, can select ASN according to AID, after the business success, RNC also selects ASN according to the AID information among the TID.
Particularly, can on RNC, dispose the corresponding relation of each ASN and AID section; And, can also be according to the volume of business of ASN, the AID segment limit that configuration and its volume of business are complementary.If the Capacity Ratio of ASN is lower, then the manageable number of users of ASN is few, if the capacity of ASN is big, the manageable number of users of ASN is just many so.For example: suppose 5+1 ASN (ASN1, ASN2, ASN3, ASN4 ASN5) forms a service area, the capacity ratio of these 5 ASN is respectively ASN1:ASN2:ASN3:ASN4:ASN5=1:1:2:2:2; And the capacity of subsequent use ASN6 is to equate with the capacity of ASN3/ASN4/ASN5.In the case, then can be equally divided into 8 equal portions to the scope of AID, insert ASN1-ASN5 respectively.
As shown in table 1 below, when terminal initial inserted, it selected the ASN that inserts to RNC according to number Duan Laiwei of AID:
The mapping table of table 1 AID section and ASN
And in user's access procedure, ASN can give mobile subscriber's distribution T ID, can comprise the information of AID section among the TID of distribution, and its concrete distribution method is as shown in table 2 below:
The TID that table 2 ASN distributes
The user inserts after the success, in the mobile network, will use TID to come identifying user.
Simultaneously, between RNC and ASN, also need set up the service condition testing mechanism.For example, RNC periodically sends detect-message and gives ASN, requires ASN to return its operating state.If the work state information that ASN returns shows its abnormal state or RNC and after the transmit status detect-message, in the time of confirming, does not receive the message that ASN returns; Explain that then this ASN can not carry out operate as normal, RNC is last need to carry out the disaster tolerance processing to ASN.At this moment, the business on this ASN is interrupted, and the terminal use will insert again.
RNC detect ASN unusual after, with the AID section and the mapping table of ASN revised on the RNC, RNC need notify ASN6 simultaneously, makes the correct TID of ASN6 distribution.Suppose that ASN3 has withdrawed from service, so, will replace ASN3 that service is provided as subsequent use ASN6.At this moment, amended form is as shown in table 3 below:
The mapping table of amended AID section of table 3 and ASN
At this moment, ASN is that the information of the AID section that comprises among the TID of terminal distribution is as shown in table 4 below:
The TID that ASN distributes behind table 4 disaster tolerance
After this, ASN3 recover normal after, can be again with ASN3 as subsequent use ASN, and need not business is switched back on the ASN3.
Below will combine concrete applying examples that the enforcement of technical scheme of the present invention is done further to introduce.
As shown in Figure 3, set up an ASN service area, this service area is made up of a plurality of ASN (for example during the 5+1 networking, ASN1 under the normal condition, ASN2, ASN3, ASN4, ASN5 are host apparatus, ASN6 is subsequent use), forms N+1 disaster tolerance mode.Should be described below with the concrete handling process of example:
Step 1, initial networking, each access control equipment (being RNC in this example) all is the IP networking with each ASN in the ASN service area, can intercommunication;
Step 2 is configured the mapping table of AID section and ASN on each RNC;
Step 3, when the user inserted for the first time, RNC selected corresponding ASN according to number segment information of user AID, promptly went up the configured corresponding relation table according to RNC, selected the corresponding ASN (for example being ASN3) of the affiliated number section of user AID; ASN3 gives this user's distribution T ID in the process that inserts, and comprises this user's AID information (partial information) among the TID;
Step 4, after this user inserted success, when carrying out business, RNC is last only to see TID, RNC takes out AID information from TID, insert on the successful ASN (being ASN3) before being linked into to guarantee to make this user;
Step 5, user terminal carries out normal business;
Step 6 occurs unusual and when withdrawing from service, the business of this user terminal will have interrupts in short-term when RNC detects ASN1;
Step 7, this user terminal insert automatically again, and RNC will select subsequent use ASN6 to provide professional for this mobile subscriber, and at this moment, the interconnected situation of each ASN is as shown in Figure 4 in RNC and the ASN service area.
Step 8, ASN3 will be as new subsequent use ASN after recovering normally.
