Step 101, femto base station power on and begin to start the radio configuration process.
Step 102, femto base station obtain the search band information from the BSC side.
Step 103, femto base station enter the operating handset pattern, begin search frequency information on every side.
Step 104, search suitable frequency, to BSC and radio operation maintenance centre (OMCR, Operation﹠amp; Maintenance Center for Radio) reports.
Step 105, OMCR carry out radio configuration and store relevant information searching for successful base station.
Step 106, femto base station enter the base station mode of operation.
In sum, adopt above-mentioned existing way to manage, femto base station passes through from line search, and the frequency information around reporting is given OMCR; According to the result who reports, the background net management personnel carry out the selection and the configuration of wireless parameter, make the base station operate as normal.This way to manage has been simplified the frequency planning process to femto base station greatly, has to a certain degree satisfied instructions for use.Yet, under the situation that the femto base station scale further increases, need artificial parameter configuration that participates in and management to be faced with still that configuration quantity is huge, the problem of difficult management.If can realize the automation mechanized operation of parameter configuration, then can solve artificial participation configuration, the configuration quantity that configuration caused of this manualization is huge, the problem of difficult management.There is not the Managed Solution of realizing the automation of femto base station parameter configuration at present as yet.

Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
Below prior art and the present invention are compared elaboration, to embody the advantage of the present invention better with respect to prior art.
With regard to prior art, as shown in Figure 1, the result that the background net management personnel report according to femto base station carries out the manualization selection and the configuration of wireless parameter, makes base station energy operate as normal.
For the present invention, contrast prior art scheme as described in Figure 1, the present invention makes improvements, and as shown in Figure 2, may further comprise the steps:
Step 201, femto base station power on and begin to start the radio configuration process.
Step 202, femto base station obtain the search band information from the HCS side.

In sum, adopt above-mentioned way to manage, femto base station is according to Home eNodeB transceiver station configuration server (HCS, HomeBTS Configurate Server) some restriction range that issue, described in step 203, not only search for available frequency set, also search for the set of corresponding adjacent area simultaneously; Described in step 205, in BSC, increase Automatic Frequency Planning, automatic adjacent section configuration, with the automatic generation of the wireless parameters such as frequency and adjacent area of finishing the work; Described in step 206, the standing part with base station parameter disposes together to the base station again.At this moment, the base station enters operating state.Because parameters such as frequency, adjacent area choose configuration automatically by BSC and give the base station, the OMCR side does not have these parameter informations, can't manage and maintenance work the base station.Like this, just need OMCR dynamically to obtain these parameters.Equally, after femto base station withdrawed from service, the data of this base station were also just nonsensical again, also need to dispose from the OMCR side.
So far drawn the notion of backward supervision base station parameter, be handed down to way that BSC issue base station again by the webmaster personnel from OMCR with respect to the traditional base station parameter, the present invention has carried out reverse dynamic management for the parameter of base station, the no matter modification of base station parameter, deletion or the newly-increased renewal that is brought, and obtaining of base station parameter all is the reverse procedure that BSC notice OMCR carries out subsequently, described in step 208, this technology also answers base station parameter to produce in the automatic formation and the configuration of BSC side.As seen, OMCR carries out the renewal of base station parameter by the BSC notice, and the process of this reverse reconstruct and configuring base station parameter is equivalent to the base station parameter that OMCR dynamically obtains from BSC, and realizes the automatic management to the base station parameter configuration.In a word, the present invention is by the process of reverse reconstruct and configuring base station parameter, the OMCR side can be upgraded the relevant parameter of base station dynamically, this dynamic access and management for femto base station provides necessary means, thereby employing the present invention, can solve in the prior art difficult management problem, improve the efficient of large scale deployment and management GSM femto base station greatly for the extensive femto base station parameter of dynamic access.
Below the technical scheme of backward supervision base station parameter of the present invention is specifically addressed.
A kind of method of backward supervision base station parameter, this method comprises: the base station parameter that OMCR reports according to BSC changes, and the base station parameter of OMCR side is upgraded, and realize automatic management to the base station parameter configuration.
Wherein, realize reporting the mode that reports that is adopted to comprise: increment reports mode or full dose to report mode.Here, report the difference of mode, cause OMCR according to BSC report the renewal of being carried out also different, below set forth respectively.
First kind of situation: adopt increment to report the situation of mode; Give the correct time on the increment, can report the notify list of single base station or a plurality of base stations to give OMCR.Wherein, the information in the notify list comprises: this two category information of variable condition of current base station number and current base station parameter, and, can comprise this two category information of single base station in the notify list, also can comprise this two category information of a plurality of base stations.
When adopting increment to report mode, OMCR upgrades specifically according to reporting of BSC and may further comprise the steps:
Step 301, BSC report OMCR according to the variable condition of current base station parameter with corresponding synchronous update request.
Here, synchronously update request comprises: the variable condition of current base station number and current base station parameter.Wherein, basic station number is the global unique device number at femto base station, be in HCS unique configuration, have uniqueness for each femto base station.Guaranteed the uniqueness of the base station parameter managed like this.The variable condition of current base station parameter is used for the method for synchronization of OMCR differentiation to base station parameter.Take the variable condition of current base station number and current base station parameter, can clearly identify like this: the variable condition of a pairing base station parameter in base station, be convenient to the variable condition of follow-up OMCR, corresponding base station parameter carried out in same base station upgrade according to base station parameter.
Step 302, OMCR receive synchronous update request and resolve, carry out the synchronous renewal of base station parameter according to the variable condition of the current base station parameter that parses.
Here, the variable condition of current base station parameter comprises: the base station is inserted and is produced state, the base station of newly-increased parameter and withdraws from the state of service and deletion parameter or the state that the base station personalizing parameters is revised.Owing to there is the variable condition of multiple current base station parameter, therefore, when adopting increment to report mode, OMCR comprises following two kinds of specific implementations according to the renewal of carrying out that reports of BSC.
First kind of specific implementation: when the variable condition of the current base station parameter that parses is specially: when the state of service and deletion parameter is withdrawed from the base station, the detailed process of upgrading comprises: OMCR is according to the base station parameter of current base station number removing current base station correspondence, and the renewal local data base.
Second kind of specific implementation: when the variable condition of the current base station parameter that parses is specially: when the state of newly-increased parameter or state that the base station personalizing parameters is revised are inserted and produced in the base station, the detailed process of renewal comprised: OMCR sends base station parameter request corresponding to current base station number to BSC; BSC reports the base station parameter of request to give OMCR; OMCR upgrades local data base according to the base station parameter that comes from BSC.
It is to be noted: at the variable condition of current base station parameter, the state that newly-increased parameter was inserted and produced in the base station is: the state the when base station is dynamically inserted, and the wireless messages that this moment, the BSC lateral root reported according to the base station carries out dynamic auto generation of base station parameter and configuration; The state that the base station personalizing parameters is revised is: the state when the HCS side is made amendment to the base station parameter of certain base station; The state that service and deletion parameter are withdrawed from the base station is: the state when service is withdrawed from certain base station.
Second kind of situation: adopt full dose to report the situation of mode; Give the correct time on the full dose, can report a full dose parameter request to be notified to OMCR.
When adopting full dose to report mode, OMCR upgrades specifically according to reporting of BSC and may further comprise the steps:
Step 401, BSC report OMCR with the full dose parameter request.
After step 402, OMCR receive the full dose parameter request, get access to basic station number from all station lists of the current management of BSC, OMCR is to the base station parameter request of BSC transmission corresponding to the basic station number that obtains.
Step 403, BSC report the base station parameter of request to give OMCR, and OMCR upgrades local data base according to the base station parameter that comes from BSC.
Here, the BSC that more than relates to comprises according to the base station parameter that request reported of OMCR: HCS is the personalizing parameters of each base station configuration, with base station working frequency points set and adjacent area set that BSC generates automatically, this two classes parameter needs OMCR oppositely to obtain.Personalizing parameters be HCS side configuration with respect to different femto base stations and different base station wireless parameters is a fixed configurations; And template parameter on the other side be the OMCR side set for the identical cover base station wireless parameter in all base stations; Add base station working frequency points set and adjacent area set that BSC generates automatically, they constitute the complete base station parameter set of base station jointly.
In sum, the present invention produces on the basis of base station wireless parameter automatically at BSC, has realized the dynamic base station parameter management of OMCR side.By automatic generation and dynamic management to the femto base station wireless parameter, solved largely that femto base station inserts in a large number and the frequent migration situation under it is carried out the inefficiency of parameter management even the problem that can't realize.Adopt the present invention, further improved the efficient of the large scale deployment and the application of femto base station, also make the access advantage of femto base station freedom and flexibility and the automation that it manages is fully reflected.The present invention mainly is the realization at the backward supervision base station data of step 208 among Fig. 2, below specifically sets forth.
Example one: because therefore the dynamic needs of the process of reverse reconstruct and configuring base station parameter, will carry out the management of parameter to it as long as there is the base station parameter of base station to take place to change, as shown in Figure 3, base station parameter changes the realization flow that reports and may further comprise the steps:
Newly-increased parameter is inserted and produced in step 501, base station; Change execution in step 504 over to.
Service and deletion parameter are withdrawed from step 502, base station; Change execution in step 504 over to.
Step 503, base station personalizing parameters are revised; Change execution in step 504 over to
Step 504, BSC produce corresponding synchronous update request according to current base station parameter variable condition.
Example two: take increment to report mode or full dose to report mode to realize situation about reporting.As shown in Figure 4, the BSC realization flow of taking difference to report mode to report may further comprise the steps:
Data in step 601, the synchronous update request of BSC buffer memory.
Step 602, judge whether the local cache district is full, if then change execution in step 604 over to; Otherwise, illustrate that the long-term link problem of BSC and OMCR has hindered obtaining of base station parameter, then execution in step 603.
Step 603, employing increment report mode to report synchronous update request to give OMCR.
Step 604, employing full dose report mode to report the full dose parameter request to give OMCR.
Example three: OMCR carries out more news of base station parameter, and as shown in Figure 5, the realization flow of renewal may further comprise the steps:
Step 701, judgement report whether mode is that increment reports mode, if then execution in step 702; Otherwise, change execution in step 703 over to.
Step 702, judge that whether the variable condition of the current base station parameter in the synchronous update request is: service and deletion parameter are withdrawed from the base station, if, then change execution in step 704 over to, otherwise, change execution in step 705 over to.
Step 703, obtain all station lists of current BSC management, change execution in step 705 over to.
Step 704, OMCR remove the base station parameter of corresponding base station, upgrade local data base and demonstration.
Step 705, OMCR send the base station parameter request of corresponding base station to BSC.
Step 706, BSC report the base station parameter of request to give OMCR, and OMCR upgrades local data base and demonstration according to the base station parameter that comes from BSC.
As shown in Figure 6, a kind of system of backward supervision base station parameter, this system comprises: administrative unit, be used for the base station parameter that OMCR reports according to BSC and change, the base station parameter of OMCR side is upgraded, and realize automatic management the base station parameter configuration.
Here, administrative unit further comprises: reporting module and update module.Owing to report the mode difference, therefore, the specific implementation of reporting module and update module is also different.
First kind of specific implementation: adopting increment to report under the situation that mode realizes reporting, reporting module is used for the variable condition of BSC according to the current base station parameter, and corresponding synchronous update request is reported OMCR.Wherein, synchronously update request comprises: the variable condition of current base station number and current base station parameter.Update module is used for OMCR and receives synchronous update request and parsing, carries out the synchronous renewal of base station parameter according to the variable condition of the current base station parameter that parses.
Second kind of specific implementation: adopting full dose to report under the situation that mode realizes reporting, reporting module is used for BSC the full dose parameter request is reported OMCR.Update module after being used for OMCR and receiving the full dose parameter request, gets access to basic station number from all station lists of the current management of BSC; OMCR is to the base station parameter request of BSC transmission corresponding to the basic station number that obtains; BSC reports the base station parameter of request to give OMCR; OMCR upgrades local data base according to the base station parameter that comes from BSC.
Wherein, adopting increment to report under the situation that mode realizes reporting, update module, be further used for being specially: when the state of service and deletion parameter is withdrawed from the base station when the variable condition of the current base station parameter that parses, OMCR is according to the base station parameter of current base station number removing current base station correspondence, and renewal local data base and demonstration.Perhaps, when the variable condition of the current base station parameter that parses is specially: when the state of newly-increased parameter or state that the base station personalizing parameters is revised are inserted and produced in the base station, described OMCR sent base station parameter request corresponding to current base station number to BSC; BSC reports the base station parameter of request to give OMCR; OMCR upgrades local data base and demonstration according to the base station parameter that comes from BSC.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
