Embodiment two
With reference to Fig. 2, show the flow chart of steps according to a kind of group Intranet strange land cut-in method of the embodiment of the invention two.
Present embodiment user data information from HSS carries out the angle of HSS data sync when upgrading (comprise increase, deletion and revise user data information), group of the present invention Intranet strange land access scheme is described.
Group's Intranet strange land cut-in method of present embodiment may further comprise the steps:
Step S202: have HSS to carry out user data information in group's Intranet among interconnected a plurality of HSS and upgrade, trigger and whether carry out the selection of HSS data sync.
In the present embodiment, group's Intranet has a plurality of residential quarters, and each residential quarter might become cell-of-origin or Target cell, and each residential quarter has HSS.All HSS of all residential quarters in this group's Intranet interconnect.Carry out distinguishing data sync according to dependent instruction such as HSS configuration management instruction between the interconnective HSS, all synchronous as all customer data information among all HSS, perhaps, certain customers' data message among all HSS is synchronous, perhaps, all customer data information synchronization among the section H SS, perhaps, the certain customers' data message among the section H SS is synchronous etc.
Owing to be cross-region between the various places HSS of group's Intranet, so generally rely on public network (as the internet net) to connect and intercommunication.Simultaneously, consider information security, local HSS can be through a CE(Custom Edge, Customer Edge router), then by VPN(Virtual Private Network, Virtual Private Network) arrive the CE in strange land, arrive the HSS in strange land again.
The user data information of HSS upgrades operations such as comprising increase, deletion and modification user data information, when having HSS to carry out the user data information renewal among interconnected a plurality of HSS, provide and whether the user data information that upgrades is carried out the selection of data sync, and then operate accordingly according to selection result.Need to prove, present embodiment is chosen as example to carry out data sync, but those skilled in the art should understand, in actual applications, also can not provide selection, system directly is defaulted as and carries out data sync, and at this moment, the renewal of user data information operation directly triggers the data sync operation of carrying out the HSS in the respective range.
When a kind of selection of whether carrying out the HSS data sync can be carried out configuration operation by the management station at some HSS, show the option of " whether being synchronized to other HSS " at the configuration operation interface.If select this option, after then configuration management was instructed down, local HSS revised local database, and the HSS to other sends the configuration management instruction simultaneously, makes other HSS also revise the user data information in the corresponding database.Certainly, in actual applications, other suitable configuration management mode is suitable for too, and the present invention is not restricted this.
Step S204: carry out the HSS of user data information renewal according to the selection of HSS data sync, generate HSS configuration management instruction.
Also be, whether carry out the selection of data sync according to user input, generate corresponding HSS configuration management instruction, include the information of carrying out data sync or not carrying out data sync in this instruction, be used to indicate for the user data information that upgrades whether carry out data sync.
Step S206: carry out HSS that user data information upgrades according to HSS configuration management instruction, judge whether and need carry out data sync to the user data information that upgrades, if do not need, execution in step S208 then; If need, then execution in step S210.
Need to prove that in the present embodiment, setting is not when needing to carry out data sync, only in local HSS updating user data information; When needs carry out data sync, in all HSS of the group's Intranet that interconnects, carry out data sync.But those skilled in the art should understand, data sync can also only be carried out between section H SS, carry out data sync as three HSS to appointment among 5 HSS, then at this moment, the information of also carrying the HSS that carries out data sync of appointment in the HSS configuration management instruction, this information can send by a HSS to appointment; Also can send to all HSS, and then judge whether to have specified this HSS by HSS, if specified this HSS then to carry out data sync, if do not specify this HSS, then abandon this instruction.
For example, be example with the HSS of Target cell, when the HSS of Target cell carries out user data information when upgrading, the HSS of Target cell receives HSS configuration management instruction; According to HSS configuration management instruction, judge whether described renewal needs to carry out data sync; If do not need to carry out data sync, then in local HSS, carry out described renewal; If need carry out data sync, then described renewal is synchronized among other HSS of group's Intranet.Preferably, can also refer to the synchronous HSS scope of given data, also, which HSS is carried out data sync, at this moment, if need carry out data sync, then determine that according to HSS configuration management instruction needs carry out the scope of other HSS of data sync; Carry out the scope of other HSS of data sync as required, carry out the data synchronization updating of all HSS in local HSS and the described scope.
Step S208: when not needing to carry out data sync, in local HSS, carry out user data information and upgrade, finish this and upgrade operation, change step S212 and carry out.
Step S210: when needs carry out data sync, the renewal of user data information is synchronized among other HSS of group's Intranet, finishes this data sync operation, change step S212 and carry out.
For example, the table of the HSS POOL that is made up of all HSS of group's Intranet one of each HSS configuration is preserved IP except local HSS, other all HSS address, to guarantee synchronous object in this table.
Step S212: when group's Intranet user was moved to the Target cell in strange land from the cell-of-origin of group's Intranet, Target cell received the strange land access request that this user sends.
In the present embodiment, need carry out whole network data with the user data information renewal is example synchronously, and then in this step, the HSS of cell-of-origin and the HSS of Target cell carried out data sync, had identical user data information.
Preferably, in the present embodiment, request is inserted to be example along with request in the strange land, then in this step, when group's Intranet user is moved to the Target cell in strange land from the cell-of-origin of group's Intranet, Target cell receive that this user sends along with request.Also namely, the user inserts from this locality to the strange land and can adopt the process of adhering in the strange land then in local attachment removal earlier.But it should be understood by those skilled in the art that other suitable access request is also applicable
Step S214: Target cell is judged the user data information of whether preserving group's Intranet user that migration comes among the HSS of Target cell, if not, and execution in step S216 then; If, execution in step S218 then.
Step S216: when preserving the user data information of the next group's Intranet user of migration among the HSS of Target cell, refuse this user's access, finish this user's strange land Target cell access process.
Step S218: when preserving the user data information of the next group's Intranet user of migration among the HSS of Target cell, Target cell allows this user strange land to insert Target cell according to this user data information.
By present embodiment, when group's Intranet user in this locality the time, be in normal access state because can in local HSS, finding the log-on message (being user data information) of oneself; When this user leaves the residential quarter of local network covering, owing to search less than signal and cause local detach(attachment removal), if searched the signal in new this locality (strange land), owing in new this locality log-on message is arranged equally, so can successfully adhere to, the realization strange land is normally inserted.By present embodiment, a kind of group's Intranet strange land access way of simple economy is provided, can realize simply and effectively that the strange land of Special Interest Group Intranet user is inserted.
Embodiment three
With reference to Fig. 3, show the flow chart of steps according to a kind of group Intranet strange land cut-in method of the embodiment of the invention three.
The data sync attribute angle of present embodiment user data information from HSS describes group of the present invention Intranet strange land access scheme.Also be, set each user data of users information in the present embodiment and all have the data sync attribute, this attribute list understands whether this user data of users information has carried out data sync, by changing this attribute, can make the user data information that does not carry out data sync carry out data sync again, also can cancel the data sync of carrying out the user data information of data sync.
Below, be example with the data sync attribute of the user data information among the HSS of modifying target residential quarter, group's Intranet strange land cut-in method of present embodiment is described, may further comprise the steps:
Step S302: the HSS in the Target cell receives data sync and sets instruction.
Wherein, data sync is set instruction and is used for whether synchronous the user data information among the HSS of Target cell carried out setting.
In the present embodiment, can concentrate the data sync attribute of already present user data information among the HSS of Target cell is set, can only set certain customers' data message, also can set the whole user data informations among this HSS.At this moment, HSS receives data sync and sets instruction, and when being defaulted as when the whole user data informations among this HSS are set, then data sync is set the content that can not carry concrete designated user data message in the instruction; When only the certain customers' data message among this HSS being set, then data sync is set the content that can also carry concrete designated user data message in the instruction, as the number of carrying segment limit in the instruction, the user data information in this number segment limit set etc.
Step S304: set instruction according to data sync, obtain the user data information that need carry out described setting.
Step S306: set instruction according to data sync, determine whether and to carry out data sync to the user data information that obtains, if need carry out data sync, then execution in step S308; If do not need to carry out data sync, then execution in step S310.
Step S308: when data sync setting instruction indication is carried out data sync to the user data information that obtains, then the user data information that obtains is synchronized among other HSS execution in step S312.
As, if data sync is set the instruction indication user data information of a certain section all is set at when carrying out data sync, no matter then whether the user data information of this number section carried out data sync, all it is synchronized to again among other HSS except local HSS in group's Intranet.Certainly, in actual applications, also can be only with in this number section, the user data information that did not before carry out data sync is synchronized among other HSS.
Step S310: set the instruction indication when data sync and the user data information that obtains is not carried out then only keeping the user data information that obtains when synchronous in local HSS, delete the user data information of preserving among other HSS that obtains, execution in step S312.
Equally, indication is not carried out data sync to the user data information of a certain section if data sync is set instruction, no matter then whether the user data information of this number section carried out data sync, all only in local HSS, keep the user data information of this number section, delete the user data information of this number section of preserving among other HSS simultaneously.Certainly, in actual applications, also can carry out the user data information of data sync before and from other HSS, delete only with in this number section, do not carry out not processing of data sync.
Step S312: when group's Intranet user was moved to the Target cell in strange land from the cell-of-origin of group's Intranet, Target cell received the strange land access request that this user sends.
In the present embodiment, the HSS of cell-of-origin and the HSS of Target cell carried out the data sync of part or all of user data information.
Preferably, in the present embodiment, request is inserted to be example along with request in the strange land, then in this step, when group's Intranet user is moved to the Target cell in strange land from the cell-of-origin of group's Intranet, Target cell receive that this user sends along with request.
Step S314: Target cell is judged the user data information of whether preserving group's Intranet user that migration comes among the HSS of Target cell, if not, and execution in step S316 then; If, execution in step S318 then.
Step S316: when preserving the user data information of the next group's Intranet user of migration among the HSS of Target cell, refuse this user's access, finish this user's strange land Target cell access process.
Step S318: when preserving the user data information of the next group's Intranet user of migration among the HSS of Target cell, Target cell allows this user strange land to insert Target cell according to this user data information.
Need to prove, present embodiment is example with the Target cell, but it should be understood by those skilled in the art that any one residential quarter in a plurality of residential quarters of group's Intranet all might become Target cell, therefore, the scheme of present embodiment is applicable to all residential quarters in group's Intranet.In addition, data sync is set instruction also can set the HSS scope of carrying out data sync or not carrying out data sync, and then, when data sync was carried out in indication, only the HSS in this HSS scope just carried out data sync; Equally, when indication is not carried out data sync, only delete the relative users data message among the HSS in this HSS scope.
Pass through present embodiment, can set via the data sync attribute, carry out concentrating synchronously or concentrating and cancel synchronously of user data information, on the basis of inserting in the strange land of realizing the Special Interest Group Intranet user simply and effectively, further realized neatly, the strange land of controllable group Intranet user inserts.

When carrying out user data information when synchronous, HSS POOL function treatment as shown in Figure 6, when at certain HSS change user data information the time, such as increasing, delete at HSS2 or the modification user data information, user data information database write on HSS2 is fashionable, can select simultaneously in the HSSPOOL every other HSS equipment to issue the operation of corresponding user data information, make them also carry out the corresponding user data information updating.Can guarantee that like this user data information on the HSS all in the HSS POOL is consistent all the time.For example, certain user USER is opened an account at HSS2 equipment, account-opening simultaneously, selection other HSS in the HSS POOL issue the data sync setting, then other HSS among the HSS POOL also will increase this user data information, when some day, this user went on business to the HSS5 region (HSS5 is in this HSS POOL), the local user who then still can be used as HSS5 normally inserts, because this user data of users information is arranged in the user data information of HSS5 equally.
In addition, the user data information that carries out at a certain HSS increases operation, can select also not that other HSS carry out data sync in the HSS POOL, can realize the setting that only can insert under local EPC network environment the user.For example, certain user USER is opened an account at HSS1 equipment, account-opening simultaneously, select not that other HSS issue synchronous setting in the HSS POOL, then other HSS among the HSS POOL can not increase this user data information, and then this user only can insert under the local EPC network environment under the HSS1.Need be increased in the authority that inserts under the Intranet EPC of other groups environment as this user, can be in HSS1 this user data made amendment and be synchronized in other HSS equipment among the HSSPOOL.
Present embodiment is by HSS POOL function, reach the data sync that support changes the HSS user data information additions and deletions among the HSS POOL, realized more simple more economic strange land access way, especially in the industry of group's Intranet (as certain group internal transprovincially) core net EPC equipment network, be suitable for, can realize simply and effectively that the strange land of Special Interest Group Intranet user is inserted.
The present invention is based on group's Intranet industry EPC equipment and do not consider that charging policy and user disperse wide characteristics less, propose a kind of realize simple and the low scheme of cost, solved the regional problem that inserts and carry out corresponding service in group's Intranet user strange land in the sector application.By the solution of the present invention, make: (1) networking is more simple, only needs all HSS are linked together, and reduces networking cost; (2) only increase corresponding HSS POOL functional unit at HSS, as, for data management and the synchronous functional unit of configuration data of HSS POOL, can realize the demand that zone, group Intranet user strange land Intranet inserts, reduced software development cost; (3) be different from the roaming function of public network, at Special Interest Group application core net EPC equipment network, provide a kind of new strange land to insert thinking.
Each embodiment in this specification all adopts the mode of going forward one by one to describe, and what each embodiment stressed is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.For system embodiment, because it is similar substantially to method embodiment, so description is fairly simple, relevant part gets final product referring to the part explanation of method embodiment.
