Description
Technical field
The present invention relates to moving communicating field, particularly mobile network's maintenance technology.
Background technology
Along with the fast development of mobile communication business, the application of mobile data and multimedia communication will be more and more widely, in the near future, even will become the main business that mobile communication is carried above traditional speech.And traditional second generation global system for mobile communications (Global System for mobileCommunication, abbreviation " GSM ") mobile communications network can't adapt to this new development trend, for this reason, GSM will progressively carry out the transition to 3-G (Generation Three mobile communication system).Wherein, third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") Wideband Code Division Multiple Access (WCDMA) (the Wideband Code Division Multiple Access of institute's standard, be called for short " WCDMA ")/universal mobile telecommunications system (Universal Mobile Telecommunications System, be called for short " UMTS ") constantly improve and the mature technique standard with it, with its flexible net framework, level and smooth evolution pattern, many advantages such as effective investment, and develop into the major technique of 3G (Third Generation) Moblie gradually, and accepted by increasing mobile communication carrier and equipment supplier.
According to the 3GPP related protocol, the land radio access web of WCDMA system (UMTS TerrestrialRadio Access Network, be called for short " UTRAN "), form by base-station node (claiming B node, NodeB again) and radio network controller (Radio Network Controller is called for short " RNC ").Wherein, comprise logic function modules such as coffret unit and base stations control part among the NodeB.In UTRAN, RNC is in the driver's seat, is used for distributing being attached thereto with control or the Radio Resource of relevant NodeB, and the conversion while that NodeB finishes the data flow between the interface also participates in a part of RRM.Main Radio Resource is conceptualized as home cell (LocalCell) and home cell group (LocalCellGroup) among the NodeB, and these resources will be used to set up sub-district (Cell) and access terminal.
Interface between NodeB and the RNC is an Iub interface, is the standard interface of an opening, supports different equipment suppliers' equipment to connect by Iub interface.In the standard agreement on the Iub interface, comprise the application protocol of chain of command, base-station node application protocol (NodeB Application Protocol is called for short " NBAP ").The major function of NBAP agreement has: the sector configuration management; The monitoring of Radio Link, management; The measurement of conventional channel, dedicated channel; SIM system information management or the like.The Communication Control port of Iub interface (Communication Control Port is called for short " CCP ") is the important channel of carrying NBAP signaling.
In the 3G (Third Generation) Moblie network, the user need adjust the position of NodeB in network through regular meeting because of the reason of system load balance, comprising the variation of physical location or the adjustment of transmission link; Can be divided into inner RNC migration and stride two kinds of situations of RNC migration from the relation of NodeB and RNC.The migration of NodeB as shown in Figure 1, NodeB1 moves RNC11 from RNC10, networking before the dotted line representative resettlement, networking after the solid line representative resettlement, be not difficult to find, in NodeB Reparenting, the transmission link relevant with NodeB, sub-district, proximity relations or the like resource all needs to carry out migration operation.
At present, the user need finish the migration of NodeB by following operation:
1, deletes sub-district and neighbouring relations on this NodeB;
2, delete signaling link, the resource such as control link etc. of this NodeB association;
3, delete all PVCs (Permanent Virtual Circuit is called for short " PVC ") bearing link of this NodeB association;
4, delete the physical link of this NodeB;
5, increase the physical link of this NodeB;
6, increase all PVC bearing links of this NodeB association;
7, increase signaling link, the resource such as control link etc. of this NodeB association;
8, increase sub-district and neighbouring relations on this NodeB.
This shows, actual migration process at NodeB, and the relevant mass data of NodeB needs to revise (the Iub interface protocol stack between NodeB and the RNC as shown in Figure 2), comprising physical link number, subdistrict position district, route district, service area setting, sub-district neighbouring relations etc., and relate to the change of a plurality of RNC configuration datas.Therefore, if the user utilizes existing man-machine language (Man-MachineLanguage, be called for short " MML ") the above-mentioned migration scheme of order manual implementation, its difficulty and risk are very big, not only require the user very familiar to the data and the system business of existing network, and in a single day in moving process the manual operation mistake appears, be difficult to return back to initial conditions; And the whole resettlement time can be very long, and suitable influence can be arranged the business of whole network; Being difficult to operation especially for the scene of moving NodeB in batches implements.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is, derives from the RNC relevant with the NodeB of need migration and carries out the relevant MML script of this migration, and therefrom extract the interface configuration data confession user's modification of NodeB.In the backup database of setting up, revise the interface configuration data of this NodeB according to the information of user's input, and in backup database, carry out this amended MML script.If the new interface configuration data of NodeB is correct, then in current system database, carry out this amended MML script file again; If the new interface configuration data of NodeB is incorrect, then notifies the user to import relevant information again, and remodify the interface configuration data of this NodeB according to the information of user's input.
More than core of the present invention has been done simple declaration, below according to this principle, the first execution mode NodeB moving method of the present invention is described in detail.
As shown in Figure 3, in step 301, network side is set up the backup database of current system database.
Then, enter step 302, network side is derived from relevant RNC and the relevant MML script of NodeB migration, and therefrom extracts the interface configuration data of NodeB.Because the NodeB transition process relates to a plurality of RNC, as source RNC, Target RNC, the RNC adjacent and the RNC adjacent with Target RNC with source RNC, therefore, network side in the present embodiment is the network entity on Element management system (ElementManagement System is called for short " the EMS ") level.
Specifically, network side is derived the MML script that the NodeB of current needs migration relates to according to the relationship object model from source RNC, the RNC adjacent with source RNC, Target RNC and the RNC adjacent with Target RNC, and generates the tabulation of NodeB interface configuration data automatically according to the MML script of this derivation and use for user's modification.In actual applications, the data volume of the MML script of deriving from relevant RNC is very big, but need the data of user's modification fewer, therefore supply user's modification by the interface configuration data that in the script of deriving, extracts NodeB, can user friendly greatly operation.
If there are a plurality of NodeB to need migration, network side also can generate a plurality of NODEB interface data, for user's modification.
Then, enter in the step 303, the user imports the migration information of NodeB.Specifically, the user selects to move the tabulation of NodeB and the RNC information at this NodeB place.If need the NodeB of migration to move to another RNC from a RNC, then because cell attribute can change in transition process, the user also need import Target RNC information and the contiguous RNC information of this NodeB.
Then, enter step 304, network side is revised the MML script of being derived and is carried out this amended MML script according to the information of user's input from relevant RNC in backup database.Specifically, network side sets in advance Substitution Rules, and according to the new NodeB interface configuration data of user's input the content that satisfies Substitution Rules is replaced in the backed up data storehouse, revises the interface configuration data of NodeB, generates new MML script.Concrete replacement can be divided into two kinds of situations, and a kind of is directly to replace according to the variation of interface data, and this replacement is fairly simple; Another kind is to replace conditionally, as neighboring BS relationship etc.Such as variation has taken place in object type when the sub-district, when having become contiguous RNC sub-district, need replace conditionally according to Substitution Rules.The Substitution Rules that network side sets in advance mainly are the custom rules that some parameters are replaced, how the interface parameters that has defined according to user's input generates new MML script, avoiding the coupling of instrument and network element version, thereby made things convenient for the migration between the different editions and reduced the professional degree of coupling.
Then, in the backup database of being set up, carry out this newly-generated MML script again, just in this backup database, carry out the amended MML script of information according to user's input.In the process of implementation, the processing of the contiguous RNC of this NodeB and Target RNC is different.For contiguous RNC, needing increases the sub-district related data deletion earlier of all resettlements one time again; And,, also need to increase the related data of resettlement sub-district except the sub-district related data deletion earlier of need with all resettlements increases one time again for Target RNC, in addition, be also noted that the order of configuration.
Then, enter step 305, network side judges whether the new interface configuration data of NodeB is correct.Specifically, when network side is carried out newly-generated MML script in backup database after, judge whether the new interface configuration data of the NodeB that needs migration is correct, if correct, then enter step 307, otherwise, the interface configuration data that NodeB is described is wrong, enters step 306.
In step 306, the new interface configuration data that network side notifies the user to re-enter NodeB, and remodify the MML script according to user's input.Specifically, similar with step 304, the new interface configuration data of the NodeB that network side re-enters according to the user in the backed up data storehouse is replaced the content that satisfies Substitution Rules, remodify the interface configuration data of NodeB, generate new MML script, in this backup database, carry out this newly-generated MML script, the just amended MML script of information that re-enters according to the user again.After finishing this step, return back to step 305 again, judge whether the new interface configuration data of NodeB is correct.
This shows, network side is by setting up the backup database of current system database, in backup database, the MML script is made amendment and carry out, correctness with check NodeB interface configuration data, and when the NodeB interface configuration data is made mistakes, support rollback operation, avoided the situation that the system that causes owing to manually-operated mistake can't rollback in transition process.
If the new interface configuration data of the NodeB that need move is correct, then enter step 307, network side is carried out newly-generated MML script in current system database, just the amended MML script of importing according to the user of information.Network side is finished the migration to this NodeB by carrying out the configuration that amended MML script changes the RNC of this NodeB.Certainly, even the new interface configuration data of the NodeB that need move is correct, the user also can determine not move this NodeB, promptly do not enter this step, but the operating process that the user carries out when not changing the migration decision-making of NodeB in the present embodiment, only is discussed generally speaking.
What deserves to be mentioned is,, then on each RNC, carry out the MML script successively, finish the data modification work of each NodeB, the NodeB that disposable migration is all according to the order of input migration NodeB if there are a plurality of NodeB to need migration.
Be not difficult to find that present embodiment comes down to the migration of NodeB has been divided into preparatory stage and execution phase.Step 301 to step 306 is the preparatory stage, and the groundwork in the preparatory stage is to generate correct script, but the actual disposition in the network is not done any variation; Step 307 is the execution phase, carry out amended MML script once in the execution phase,, simplified manual operation with respect to the method for in network, revising configuration one by one, improved the reliability and the fail safe of NodeB transition process, and then reduced of the influence of NodeB transition process system.And, because network side revises and carries out the MML script file earlier in backup database, directly carry out in the system database and revise the correct MML script file in back, shortened the transit time of NodeB largely, the implementation that feasible batch moves NodeB becomes possibility, further improved the reliability and the fail safe of NodeB transition process, reduced of the influence of NodeB transition process system.
The second execution mode NodeB moving method of the present invention and first execution mode are roughly the same, and its difference only is, in the first embodiment, if there are a plurality of NodeB to need migration, all NodeB of then disposable migration.And in the present embodiment,, then move NodeB one by one if there are a plurality of NodeB to need migration, whenever finish the migration of a NodeB after this transition process of check whether correct, if then carry out the migration of next NodeB again.
The 3rd execution mode NodeB migratory system of the present invention comprises the NodeB and the RNC relevant with this NodeB that needs migration; Derive module, be used for deriving the associated script of carrying out this NodeB migration from relevant RNC; Modified module is used for according to the information of user's input the script that this derivation module is derived being made amendment; Executive Module is used to carry out the RNC configuration of changing this NodeB through the amended script of this modified module, finishes the migration to this NodeB; And back up and set up module, be used to set up the backup database of current system database.
Specifically, modified module is set up in the backup database of module foundation in backup, make amendment to deriving the script that module derived according to the information of user's input and the Substitution Rules that set in advance, and in this backup database, carry out amended script by Executive Module, if after Executive Module is carried out, the new interface configuration data of this NodeB is correct, then this Executive Module is carried out amended script again in current system database, change the RNC configuration of this NodeB, finish migration this NodeB.Be divided into preparatory stage and execution phase by migration with base-station node, generate correct script in the preparatory stage, but the actual disposition in the network is not done any variation, carry out once in the execution phase, with respect to the method for in network, revising configuration one by one, simplified manual operation, improved the reliability and the fail safe of NodeB transition process, and shortened the transit time of NodeB largely, reduced of the influence of NodeB transition process system.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
