Due to Home eNodeB Numerous, conventional macro base station management method is the most applicable, but adopts It is managed by self-organizing network (Self-OrganizedNetwork is called for short SON) method；To family Base station uses self-organized network management to relate generally to the parameter related to eating dishes without rice or wine, such as to radio frequency (Radio Frequency, is called for short RF) parameter, physical layer (Physical Layer is called for short PHY) self-organization network Network parameter, the management of media access control layer (Media Access Control is called for short MAC) parameter.From The method of tissue network management mainly includes three parts: self-configuring (Self-Configuration), from excellent Change (SelF-Optimization), self-healing (Self-Healing).

Self-configuring mainly Home eNodeB carries out in initialization procedure at access band or start, obtains sky The initial configuration parameters that relates to of mouth, most important in these parameters includes Neighboring Cell List.Such as WFAP In initialization procedure, can from network side server (server refers to network management system here, or Realize the server of SON function) obtain its macro base station neighbor cell list, it is possible to it is operated in terminal pattern Scanning Home eNodeB around obtains Home eNodeB list；The adjacent area family base wherein obtained by scanning The information of station is also required to be synchronized to SON server, in order to the topology of the whole network of SON system real-time servicing Information.So Home eNodeB just obtains its Neighboring Cell List at initialization procedure, including the grand base in adjacent area Stand and the information of Home eNodeB.

Self-optimizing refer to Home eNodeB provide service during, according to gather information, to parameter of eating dishes without rice or wine It is adjusted, in order to realize capacity and coverage optimization, mobile management optimization, reduces interference optimization.

Self-healing refers to when Home eNodeB breaks down or is not provided that satisfactory service, by self-organizing network pipe Reason method is fixed a breakdown automatically, or is reduced to minimum by fault impact.

During self-optimizing, also include adjacent area Automatic Optimal；Although during family's Base station initialization, Home eNodeB can obtain initial neighboring BS information, but hereafter event occurs due to network topology change or base station Barrier, or in initialization procedure, adjacent area list information is imperfect, is required for subsequently through Neighboring Cell List from excellent Change and carry out real-time update adjacent area list information.Neighboring Cell List automatically updates ensureing that whole net performance of handoffs is the heaviest Want, be also that handover optimization is correlated with.

At present Home eNodeB is simply discussed by WiMAX Forum during family's Base station initialization from Dynamic configuration, is also not involved with Neighboring Cell List and automatically updates.Additionally, WiMAX Forum does not currently also have Wireless parameter is discussed, and (such as handoff parameter covers and capacity, interference parameter etc.；Wherein handoff parameter is Refer to triggering terminal scanning, report scanning result, the threshold value of initiation handover request, and serving BS is sent out Play the threshold value of target BS switching) after initial configuration, how to carry out the flow process of self-optimizing.

Detailed description of the invention

Home eNodeB is preserved the information of the Neighboring Cell List of self, SON server preserves network Topology information, this topology information includes the adjacent area between the base station that SON server is managed The information of relation.

The Neighboring Cell List either preserved in Home eNodeB, or the whole network that SON server preserves Neighboring BS relationship between middle base station is directed to the information of neighbor base station.The Neighboring Cell List that Home eNodeB preserves In deposit is the information of the neighbor base station can being switched to from this Home eNodeB, this neighbor base station can be Macro base station, it is also possible to be other Home eNodeB, it is also possible to be those coverages macro base station and family it Between other type of base station.These neighbor base stations can belong to same operator with this Home eNodeB (NAP or NSP), it is also possible to belong to different operators (NAP or NSP), different adjacent area bases Stand and can also belong to different operators (NAP or NSP).Base station information in Neighboring Cell List at least wraps Containing one of following information: the business of base station identification information, frequency information, operator identifier and current base station Industry relation, duty, whether allow switching, whether allow delete, whether allow access etc..Wherein With the commercial relations of current base station, refer to whether exist between this neighbor base station and operator of current base station Commercial relations, if it is present represent that current base station can be switched to neighbor base station, otherwise can not switch To neighbor base station；Wherein duty can be further subdivided into the duty of base station self, Yi Jiyu The duty of the network that this base station is connected.Wherein base station type includes at least one following: macro base station, Micro-base station, femto base station, Home eNodeB；Wherein Home eNodeB type at least includes one of following: privately owned Type, publicly-owned type, mixed type.Show that base station type has at least one following purpose: during switching, Terminal can be allowed preferably to be switched to Home eNodeB serviced；Owing to serving BS is able to know which is privately owned The base station of type allows to access, therefore, it is possible to avoid terminal not allow its private base station accessed in adjacent area Switching；The reason of the duty comprising base station is, if neighbor base station is not at duty, then may be used To avoid terminal to switch to these base stations；Do not allow to delete, it may be possible to the requirement of operator, need to protect Stay its syntople；Do not allow switching, it may be possible to operator, do not allow the switching between some base station, It is probably base station and is not at duty, or at full capacity etc..

Wherein, base station identification information is including at least one of following information: base station MAC layer mark (BS ID), Prefix index, cell ID (Cell ID).

Neighboring BS relationship between base station typically follows mutual equipping rules, i.e. base station A if base station B Adjacent area, then base station B is also the adjacent area of base station A；I.e. as base station A, base station B is added to its adjacent area Time in list, then perhaps base station B adds base station A in its Neighboring Cell List to；When base station A is base When the B that stands deletes from its Neighboring Cell List, then base station B is also required to a base station A from its Neighboring Cell List Delete.

After Home eNodeB obtains initial neighboring BS information in initial network entry, its Neighboring Cell List may also need to Update.Adjacent-area list renewing includes at least one following situation: increase base station and information thereof in Neighboring Cell List, Deleting base station and information thereof in Neighboring Cell List, the base station information in Neighboring Cell List needs to update.

The renewal of the Neighboring Cell List of Home eNodeB can thus trigger by Home eNodeB oneself, it is also possible to by SON Server triggers.It is described separately both of these case below by two embodiments.

Embodiment one:

Described in embodiment one, SON server initiates the flow process of base station adjacent-area list renewing.SON services Device detects when base station Neighboring Cell List needs to update, and updates the adjacent area between the base station of the whole net self preserved Relation, and indicate the base station needing to update Neighboring Cell List to update its Neighboring Cell List.Neighboring Cell List needs more New base station can be with one of Types Below: macro base station, micro-base station, femto base station (Pico), family Base station.

The present invention can be typically applied in Home eNodeB and update the situation of its Neighboring Cell List.Referring to Fig. 1, Illustrate SON server and initiate the method that neighbor cell list of home base station updates, specifically include following step Rapid:

Step 101, SON server detects that neighbor cell list of home base station needs to update；

SON server update its preserve network topology information time, or, SON server exists When doing the mutual configuration inspection in adjacent area, can detect that neighbor cell list of home base station is the need of renewal.SON takes Business device could be aware that the state of base station in whole network (such as could be aware that base station is the most in running order Base station), it is also possible to know in network base station case that is newly-increased or that delete.

SON server judges when situations below being detected that neighbor cell list of home base station needs to update:

(1) base station information of the base station in Neighboring Cell List changes.Become from duty including base station Changing to off working state, the reason causing base station to be in off working state is probably the link being linked to base station Break down, break down in base station itself, power-off of base station, base station shutdown etc.；Now need renewal adjacent The base station information of this base station in district's list.

(2) certain base station newly-increased.Increase newly near Home eNodeB can be as Home eNodeB adjacent area base The base station stood, now needs to add this newly-increased base station and information thereof in the neighbor list.Additionally, for newly The base station increased, whether neighbor base station and current base station that SON server inspection is newly-increased exist commercial relations； If SON server can not check self, can by and other network element (such as, network management system, AAA etc.) cooperating checks.

(3) certain base station is deleted.That remove near Home eNodeB and in family's station list base Stand, now need to delete this base station and information thereof in the neighbor list.

SON server detects when the base station information in neighbor cell list of home base station needs to update or receives After neighbor cell list of home base station updates the information of result (successfully), update base station in the network self preserved Neighboring BS relationship.

Step 102, SON server is to needing the Home eNodeB transmission updating Neighboring Cell List with adjacent area row The instruction information of table more fresh information, notifies that this Home eNodeB updates Neighboring Cell List；

SON server to the adjacent-area list renewing information that Home eNodeB sends at least include following information it One: Neighboring Cell List needs neighbor base station and the information thereof increased；Neighboring Cell List needs the adjacent area deleted Base station and information thereof；The more fresh information of the base station information of base station in Neighboring Cell List.

Owing to SON server being preserved the positional information of Femto, if therefore when newly-increased in network During macro base station, then SON service understands under newly-increased macro base station coverage according to topological structure or has weight The Femto of folded covering relation, therefore SON server is able to know that be newly added in running order Macro base station as the adjacent area of which Femto, thus can trigger relevant Femto in its Neighboring Cell List Increase the information of this macro base station.This process is also applied for triggering relevant macro base station in its Neighboring Cell List Increase the information of this macro base station.Additionally, during family's Base station initialization, at the beginning of Home eNodeB can send Relevant information during beginningization is to home base station management system and/or self-organizing network server；If Home eNodeB only sends the information to home base station management system, and home base station management system also needs to handle Described information is sent to self-organized network management server.Obtained by said process self-organizing network server Know and network has increased newly one family base station, and according to the position relationship in network topology, determine which family The Neighboring Cell List of base station, front yard needs increase described Home eNodeB and information thereof.

Owing to SON server preserves the neighboring BS relationship of base station in network, therefore when network deletes certain During individual base station (including macro base station or Femto), which base station (macro base station SON server is able to know that Or Femto) Neighboring Cell List be affected, thus it is adjacent from it to trigger the affected base station of Neighboring Cell List District's list is deleted the information of described deletion base station.Additionally, Home eNodeB shutdown off-grid or from Net or during exiting, Home eNodeB can send shutdown or off-grid or off-network, or exit relevant Information is to home base station management system and/or self-organizing network server；If Home eNodeB only sends institute Information of stating is to home base station management system, and home base station management system also needs to send the information to certainly Tissue network management server.Family described in network is learned by said process self-organizing network server Base station occurs in that shutdown or off-grid or off-network, or exits, and according to the position relationship in network topology, Determine the Neighboring Cell List of which Home eNodeB to need delete described Home eNodeB and information thereof, or adjacent area List needs to update the information of described Home eNodeB.

SON server can the work shape of base station (including macro base station or Femto) in real-time detection network State, when SON server finds that certain base station is changed to off working state from duty, it is clear that at this The target BS of switching is cannot act as in the base station of off working state；It is thus desirable to from the adjacent area of associated base stations List is deleted and is in the neighbor base station of off working state, or mark this base station in the neighbor list and be in Off working state, or mark the target BS that this base station cannot be used for switching in the neighbor list.

Owing to SON server preserves the neighboring BS relationship of base station in network, therefore visit when SON server Measure certain base station in network (including macro base station or Femto) and be changed to off working state from duty Time, SON server is able to know that the Neighboring Cell List of which base station (including macro base station or Femto) is subject to Impact, thus trigger the affected base station of Neighboring Cell List and update its Neighboring Cell List, wrap in Neighboring Cell List Base station (including macro base station and Home eNodeB) containing this base station sends instruction message, indicates it to update adjacent area List；And the base station (including macro base station and Home eNodeB) comprising this base station in Neighboring Cell List sends Information in carry at least one in following information: from Neighboring Cell List, delete the base being in off working state Stand information；Or the duty updating this base station in the neighbor list is off working state, or from neighbour The information updating this base station in district's list is to cannot function as the target BS of switching, or from Neighboring Cell List The information updating this base station is the base station that cannot function as accessing.Additionally, when family's base station operation state occurs During change (and change to off working state from duty, and return to work from off working state State etc.), Home eNodeB can send the information of the work state information carrying Home eNodeB to self-organizing The webserver and/or home base station management system；If Home eNodeB only sends the information to family Base station management system, home base station management system also needs to send the information to self-organized network management Server.Learned that by said process self-organizing network server the duty of described Home eNodeB becomes Change, and according to the position relationship in network topology, determine the Neighboring Cell List of which Home eNodeB needs to delete Except described Home eNodeB and information (when duty changes to off working state) thereof or newly-increased described family Base station, front yard and information (when off working state returns to duty) thereof, or Neighboring Cell List needs Update described Home eNodeB base station information (update the duty of Home eNodeB described in Neighboring Cell List, Or update the duty with Home eNodeB self further).This process is also applied for its of Home eNodeB Use when its base station information changes；This process is also applied for other type of base station.

Additionally, when the network duty being connected of certain Home eNodeB changes (and from work State changes to malfunction, and returns to duty etc. from malfunction), Home eNodeB and/ Or self-organizing network server and/or home base station management system detect network duty and become Change；But when network changes to malfunction from duty, Home eNodeB may not report this Fault is to self-organizing network server or home base station management system.When self-organizing network server self not When can detect the network duty change that described Home eNodeB is connected, self-organizing network service can be led to Cross Home eNodeB or home base station management system learns that the connected network duty of described Home eNodeB becomes (including that Home eNodeB sends the information to self-organizing network server, home base station management system is sent out in change Sending described information to self-organizing network server, and Home eNodeB sends the information to Home eNodeB pipe Reason system, then described information is sent to self-organizing network server by home base station management system again), And according to the position relationship in network topology, determine the Neighboring Cell List of which Home eNodeB to need delete institute State Home eNodeB and information (when duty changes to malfunction) thereof or newly-increased described Home eNodeB And information (when malfunction returns to duty), or Neighboring Cell List need renewal described The information of Home eNodeB (updates the duty of Home eNodeB described in Neighboring Cell List, or updates further The duty of the network being connected with Home eNodeB).This process is also applied for other type of base station.

Step 103, after Home eNodeB receives the information described in step 102, updates its Neighboring Cell List；

Step 104, Home eNodeB sends the renewal result of this Home eNodeB of instruction to SON server Information, i.e. its result updated of notice SON server.Home eNodeB carries out the knot of adjacent-area list renewing Fruit is success or failure.

In said method, before SON server sends the information updating its Neighboring Cell List to Home eNodeB Or after receiving adjacent-area list renewing result (successfully) information that Home eNodeB sends, update its network and open up (i.e. Home eNodeB has increased neighbor base station newly, or deletes adjacent area to flutter the neighboring BS relationship of base station in structural information Base station, or the base station information of its neighbor base station changes), SON server the most just can be made to protect Information in the Neighboring Cell List of neighboring BS relationship same family base station of depositing keeps consistent.

Above-mentioned steps is also applied for other type of base station of renewal (macro base station, micro-base of SON service trigger Stand, femto base station etc.) process of Neighboring Cell List.

Specific embodiment one:

When SON detects certain base station of deletion, the network topology structure that SON preserves according to self, know Road is deleted this base station and is had influence on the Neighboring Cell List of which base station；On the one hand update in the network self preserved Base station between neighboring BS relationship, simultaneously also send information to affected base station, adjacent from it for instruction District's list is deleted this base station information.

Specific embodiment two:

When SON detects certain base station of increase, the network topology structure that SON preserves according to self, know This base station that road increases has influence on the Neighboring Cell List of which base station；On the one hand the network self preserved is updated In base station between neighboring BS relationship, simultaneously also send messages to affected base station, for instruction from it Neighboring Cell List increases this base station information.

Specific embodiment three:

When SON detect certain base station be changed to off working state from duty time, can have at two kinds Reason method.

Method one: this base station as deleting base station scenario, does same process, i.e. SON according to certainly The network topology result that body preserves is it is known which base station this base station being in off working state has influence on Neighboring Cell List.On the one hand update neighboring BS relationship between the base station in the network self preserved, also send simultaneously Message gives affected base station, deletes this for instruction and be not at duty from its Neighboring Cell List Base station information.

The network topology result that method two: SON preserves according to self is it is known that this is in inoperative shape This base station of state has influence on the Neighboring Cell List of which base station；On the one hand update in the network self preserved Neighboring BS relationship between base station, i.e. marking this base station state is off working state, and/or marks this base station not Can be used for switching, and/or mark this base station cannot be used for access.Also send messages to be affected simultaneously Base station, for instruction from its Neighboring Cell List, update this base station information, be used for showing that this base station is not at Duty, and/or cannot be used for, and/or cannot be used for accessing.

Embodiment two:

Described in embodiment two, Home eNodeB initiates the flow process of adjacent-area list renewing.As example, base station A For macro base station or Femto, base station B is macro base station or Femto.As in figure 2 it is shown, comprise the steps of

Step 201, base station A detects that the base station information in Neighboring Cell List needs to update；

Base station is able to detect that the neighbor base station and information thereof not comprised in existing Neighboring Cell List, i.e. detects To the new neighbor base station that can increase newly in its Neighboring Cell List and information thereof.

Base station can find the adjacent area not comprised in current neighbor list in the following way: 1. by it The message of the terminal to report of service finds, terminal to report message at least includes one of following message: scanning is tied Really report message, handover request message, switch indicating information.When these message occur in that Neighboring Cell List In the neighbor base station that do not comprises, then it is believed that new neighbour has been detected by terminal to report message in base station Base station, district.2. Home eNodeB finds new neighbor base station during follow up scan neighbor base station.3. base Stand (including Home eNodeB) detected by uncontrolled switching or unpredictable handover event；And it is uncontrolled Switching and unpredictable switching are that the message of the requesting terminal information sent by target BS is known.

Base station may also have alternate manner to detect neighbor base station in Neighboring Cell List to cannot function as neighbor base station, I.e. need from Neighboring Cell List, delete certain neighbor base station.

Home eNodeB detects that the situation that the base station information in Neighboring Cell List changes at least includes following One in situation: need in Neighboring Cell List to increase neighbor base station and information thereof；Or Neighboring Cell List needs Delete neighbor base station and information thereof；Or Neighboring Cell List needs to update the base station information of neighbor base station.

If WFAP detects Neighboring Cell List when changing, it is adjacent that Home eNodeB can directly update it District's list or wait SON update the Neighboring Cell List of himself again after sending instruction message.

Step 202, Home eNodeB A sends the finger with adjacent-area list renewing information to SON server Show that information, notice update the Neighboring Cell List of described Home eNodeB；

Home eNodeB A at least includes following letter to the more fresh information of the Neighboring Cell List that SON server sends One of breath: newly-increased neighbor base station and information thereof；The neighbor base station deleted and information thereof；Base station information is more Fresh information.

Step 203, after SON server receives the information that Home eNodeB A sends, to this Home eNodeB A Send the confirmation receiving this information；

This step 203 is optional step.

Step 204, the more fresh information receiving Neighboring Cell List is verified by SON server, and detects need The base station (including macro base station and Home eNodeB) of adjacent-area list renewing to be carried out, and update what self preserved The neighboring BS relationship of base station (including macro base station and Home eNodeB) in network；

The more fresh information receiving Neighboring Cell List is verified by SON server, refers to that SON service is permissible Check whether newly-increased neighbor base station and current base station exist commercial relations；If SON server self Can not verify, can by and other network element (such as, network management system, AAA etc.) cooperation carry out school Test.

What SON server detected needs the base station carrying out adjacent-area list renewing can be multiple base station, Needing the base station carrying out adjacent-area list renewing can be macro base station, can be Home eNodeB, it is also possible to be grand Base station and Home eNodeB.

SON server updates the neighboring BS relationship of base station in network according to the information received；It addition, SON According to this information, server finds whether the neighboring BS relationship of other base station is affected (according to adjacent area interworking Put or other method), if there is neighboring BS relationship other base station affected, SON server is also Notify that other base stations update its Neighboring Cell List.

The Home eNodeB carrying out adjacent-area list renewing is needed at least to include one of following base station: to described from group Knit the webserver and send the Home eNodeB of instruction information, the finger sent to described self-organizing network server Show the newly-increased neighbor base station comprised in information；The instruction information sent to described self-organizing network server In the neighbor base station of deletion that comprises；The need renewal Neighboring Cell List that check table detects is configured mutually according to adjacent area Home eNodeB.

When SON server detection Neighboring Cell List needs the Home eNodeB carrying out information updating, it is also contemplated that Equipping rules mutually.Such as, base station A detects newly-increased adjacent area B, then SON server receives this letter After breath, being not only base station A needs newly-increased adjacent area B, and base station B is also required to newly-increased adjacent area A.Base The A that stands detects to be needed to delete adjacent area B, then after SON server receives this information, be not only base station A needs to delete adjacent area B, and base station B is also required to delete adjacent area A.

Step 205a/205b, SON server to needing the base station carrying out adjacent-area list renewing (can be Macro base station and/or Home eNodeB) send the instruction information with adjacent-area list renewing information；

Needing the Home eNodeB carrying out information updating in Fig. 2 is base station A and base station B, is only used as example, In actual applications, the Home eNodeB carrying out information updating is needed can to have multiple.In the drawings, it is sent to Home eNodeB A (base station A is to send adjacent-area list renewing request message to the base station of SON server) Message be adjacent-area list renewing response message, be sent to base station B (base station B be when need update base station During the Neighboring Cell List of A, the most affected base station of its Neighboring Cell List) message be that adjacent-area list renewing please Seek message.

For indicating the information of adjacent-area list renewing at least to include one of following information: increase in the neighbor list Add neighbor base station and information thereof, or delete neighbor base station and information thereof in the neighbor list, or arrange in adjacent area Table updates the base station information of certain neighbor base station.

Step 206a/206b, Home eNodeB A and Home eNodeB B update the base station letter in its Neighboring Cell List Breath.

Its Neighboring Cell List of described renewal includes the one in following update mode: increase neighbour in the neighbor list Base station, district and information thereof, delete neighbor base station and information thereof in the neighbor list, update in the neighbor list The base station information of neighbor base station.

Step 207a/207b, Home eNodeB A and Home eNodeB B send instruction more to SON server The information of new result.

The result of adjacent-area list renewing is success or failure.

Step 207a/207b is optional step.

In said method, SON server is before sending information to the base station that Neighboring Cell List needs update Or after receiving the information that base station updates result, SON server self updates the neighbour in network between base station Cell relation (i.e. includes that base station has increased neighbor base station newly, or base station deletes neighbor base station, or the neighbour of base station District's base station information changes)；SON server is made to preserve neighboring BS relationship with in the Neighboring Cell List of base station Information keep consistent.

Base station himself Neighboring Cell List moment of renewal is one below: base station sounds to needs updates its adjacent area During list, base station directly updates its Neighboring Cell List；Or base station receives the instruction of SON server and updates it Its Neighboring Cell List is updated again after the information of Neighboring Cell List.

If SON service detection macro base station neighbor cell list needs to update in above-mentioned steps 204, the most also may be used To trigger macro base station neighbor cell list renewal process.

205b, 206b, 207b in above-mentioned steps and 102,103,104 in embodiment one step In be consistent；It it is all the process of SON server triggers base station adjacent-area list renewing.

Above-mentioned steps is also applied for the Neighboring Cell List that other type of base station (macro base station, micro-base station etc.) triggers Process.

After Home eNodeB obtains initial wireless parameter information in initial network entry, its wireless parameter may be also Need to update.The renewal of the wireless parameter of Home eNodeB can thus trigger by Home eNodeB oneself, it is also possible to By SON server triggers.Be described separately both of these case below by two embodiments, especially with Switching-related parameters updates as example.

Embodiment three:

Described in embodiment three, SON server initiates the flow process that base station wireless parameter updates.SON services After device detects that wireless parameter needs to update, instruction needs the base station updating wireless parameter to update its wireless ginseng Number.Needing the base station updating wireless parameter can be with one of Types Below: macro base station, micro-base station, slightly Base station (Pico), Home eNodeB.

The present invention can be typically applied in the situation that the base station of wireless parameter needs renewal is Home eNodeB.Below With reference to Fig. 3, illustrate SON server and initiate the method that Home eNodeB wireless parameter updates, specifically Comprise the following steps:

Step 301, SON server detects that Home eNodeB wireless parameter needs to update；

Base station gathers the performance parameter that wireless parameter is relevant, and reports to SON server.SON services The performance parameter that device is relevant according to gathering wireless parameter, and analyze these performance parameters, such as performance of handoffs, Call features, capacity and covering correlated performance, interference correlation energy；When these performances are unsatisfactory for requiring (such as comparing with certain threshold value), then which wireless parameter needs SON server can analyze Update and recommend new value to improve this performance.In addition, after wireless parameter has done and reconfigured, also need Trigger the wireless parameter updating affected Home eNodeB.

Such as performance of handoffs, comprise switching too early, switching too late, ping-pong etc., if this A little events reach to a certain degree (number or percentage), then SON server can trigger renewal family base The handoff parameter stood is to improve performance of handoffs, and these handoff parameters include: triggering terminal scanning thresholding, Triggering terminal reports the thresholding of scanning result, triggering terminal to initiate the thresholding of handover request, and service base Stand and initiate the thresholding etc. of target BS switching.

Such as covering performance, then may relate to the maximum transmission power parameter of Home eNodeB；

Such as interference free performance, then may relate to the maximum transmission power parameter of Home eNodeB；

Step 302, SON server is to needing the Home eNodeB transmission updating wireless parameter with wireless ginseng (i.e. config update request message in figure, wherein carries wireless parameter to the first information of number more fresh information More fresh information), notify that this Home eNodeB updates its wireless parameter, carry the more fresh information of wireless parameter；

As a example by handoff parameter updates, if SON server detects or knows switching too early too much, then May need to improve the threshold value of switching-related parameters, then SON server then can be this more fresh information Notify Home eNodeB.

Step 303, after Home eNodeB receives the first information described in step 302, updates wireless parameter；

Step 304, Home eNodeB sends to SON server and indicates the wireless parameter of this Home eNodeB more Second information (i.e. configuration response message in figure carries renewal object information in message) of new result, I.e. its result updated of notice SON server.Home eNodeB carries out the result of wireless parameter renewal for becoming Merit or failure.

In said method, before SON server sends the first information to Home eNodeB, or receive house (representing that Home eNodeB updates wireless parameter success) after the second information that base station, front yard sends, SON takes Business device updates the wireless parameter self preserving this Home eNodeB.

Above-mentioned steps is also applied for the renewal base station Neighboring Cell List process of SON service trigger.

Above-mentioned steps is also applied for other type of base station of renewal (macro base station, micro-base of SON service trigger Stand) wireless parameter process.

As a example by switching-related parameters updates:

Specific embodiment one:

When SON learns that certain base station premature event that switches reaches threshold value (such as more than a fixed number Mesh, or reach certain percentage), then may improve MS and initiate the thresholding of handover request, improve clothes Business base station is switched to the thresholding etc. of target BS.

Specific embodiment two:

When SON learns that certain base station event too late that switches reaches threshold value (such as more than a fixed number Mesh, or reach certain percentage), then may reduce MS and initiate the thresholding of handover request, reduce clothes Business base station is switched to the thresholding etc. of target BS.

Specific embodiment three:

Reach frequently to occur when SON learns certain region ping-pong (such as exceed some, Or reach certain percentage), then may adjust the relevant handoff threshold value of this region associated base stations.

Embodiment four:

Described in embodiment four, Home eNodeB initiates the flow process that wireless parameter updates.Base station A is macro base station Or Femto, base station B are macro base station or Femto.As shown in Figure 4, comprise the steps of

Step 401, base station A detects that its wireless parameter information needs to update；

Base station gathers the performance parameter that wireless parameter is relevant, and these performances are including, but not limited to following property Can: performance of handoffs, call features, capacity and covering correlated performance, interference correlation energy etc.；Base station is removed These performance related parameter can be reported SON server, self can also analyze and these performances Relevant parameter is the need of renewal；Such as above-mentioned these Key Performance Indicators (KPI, Key Performance Indication) when reaching certain thresholding, then which wireless parameter needs base station can analyze Update and recommend new value to improve this performance.

Such as, for performance of handoffs, comprise switching too early, switching too late, ping-pong etc., if These events reach to a certain degree (number or percentage), then base station can trigger renewal performance of handoffs be correlated with Parameter improves performance of handoffs, and these switching-related parameters include: triggering terminal scanning threshold value, touch Send out the threshold value of terminal to report scanning result, the threshold value of terminal initiation handover request, and serving BS Initiate the threshold value etc. of target BS switching.

If WFAP is through performance evaluation, when needing to update its wireless parameter, Home eNodeB can be direct Update its wireless parameter or wait that SON updates its wireless parameter after sending instruction information again.

Step 402, Home eNodeB A sends the with wireless parameter more fresh information to SON server One information (i.e. the request of the config update in figure message, carries the more fresh information of wireless parameter in message), Notice this Home eNodeB of SON server needs to update its wireless parameter；

If the wireless parameter that performance of handoffs causes updates, then Home eNodeB A sends out to SON server The first information of the wireless parameter for indicating renewal performance of handoffs to be correlated with sent can include following information extremely One of few: the new threshold value of triggering terminal scanning, triggering terminal report threshold value that scanning result is new, Triggering terminal initiates the new threshold value of handover request, and serving BS initiates target BS switching New threshold value etc..

Step 403, after SON server receives the first information that Home eNodeB sends, to this Home eNodeB Send the second information (i.e. in figure, config update request confirms message) receiving this validation of information；

This step 403 is optional step.

Step 404, the SON server more fresh information of the wireless parameter to receiving in the described first information is carried out Check and analyze.Check and analyze and mainly include one of following content:

Whether A, validity to the more fresh information receiving wireless parameter check, such as, see rationally In the range of etc., if the most in the reasonable scope, then need to readjust；

B, from overall performance, the wireless parameter more fresh information asking this Home eNodeB is commented Estimating, the renewal to certain performance-relevant wireless parameter of this Home eNodeB request, if causing this family Other degradation of base station, then this variation must control in the reasonable scope, the most in this case The more fresh information of the wireless parameter of Home eNodeB request must be adjusted by SON server, reaches as far as possible To a compromise result；This trading off also includes that this Home eNodeB is not asked more by SON server New wireless parameter is adjusted.

C, from performance of the entire network, the wireless parameter more fresh information asking this Home eNodeB is commented Estimating, the renewal of the wireless parameter of this Home eNodeB request, if causing other base that this Home eNodeB is adjacent The degradation stood, then this variation must control in the reasonable scope, the most in this case SON The more fresh information of the wireless parameter of Home eNodeB request must be adjusted by server, reaches one as far as possible Compromise result；This compromise nothing also including SON server other base station adjacent to this Home eNodeB Line parameter is adjusted, and triggers the renewal of the wireless parameter to adjacent base station, and the same SON of this process takes Business device triggers Home eNodeB wireless parameter renewal process.

Step 405a/405b, SON server to needing the base station carrying out wireless parameter renewal (can be Macro base station and/or Home eNodeB) send with the 3rd information of wireless parameter more fresh information (i.e. in figure Config update response message, or config update request message).

Wireless parameter in SON server is sent to the config update response message of base station A updates letter Breath and base station A are sent to the config update request message in the configuration change request message of SON server In the more fresh information of wireless parameter compare, can identical or the former adjust on the basis of the latter Whole.

Be sent to the 3rd information of base station A carry the renewal of wireless parameter can one of in the following way Represent:

(2) the 3rd information only with the different piece in first information wireless parameter more fresh information, bag Include:

The newest field and value thereof；

B. value is different same field and value thereof.

The Home eNodeB carrying out wireless parameter renewal is needed at least to include one of following base station: to described from group Knit the webserver and send the Home eNodeB of the first information；Need to update wireless ginseng according to performance of the entire network assessment Other Home eNodeB of number, causes wireless parameter needs to update because described Home eNodeB wireless parameter updates Other Home eNodeB.

Fig. 4 need the Home eNodeB carrying out wireless parameter renewal (as a example by handoff parameter updates) as base Stand A and base station B, is only used as example, in actual applications, needs to carry out family's base of information updating Standing, it is multiple to have.In the drawings, (base station A is to send config update request to be sent to Home eNodeB A Message is to the base station of SON server) message be config update update response message, be sent to base station (base station B is when needing the wireless parameter updating base station A to B, the most affected base of its wireless parameter Stand) message be config update ask message.

Step 406a/406b, Home eNodeB A and Home eNodeB B update its wireless parameter.

Step 407a/407b, Home eNodeB A and Home eNodeB B send instruction nothing to SON server Line parameter updates the 4th information (i.e. the transmission config update confirmation in A base station in figure, or B base station of result Send config update response)；The result that wireless parameter updates is success or failure.

Step 407a/407b is optional step.

In said method, before SON server sends the 3rd information updating wireless parameter to base station, Or after receiving the 4th information that base station sends wireless parameter renewal result (successfully), SON server Self update the wireless parameter of base station in network.

Base station himself wireless parameter moment of renewal is one below: it is wireless that base station sounds to needs updates it During parameter, base station directly updates its wireless parameter；Or base station receives the instruction of SON server and updates it Its wireless parameter is updated again after the information of wireless parameter.

If SON service detection macro base station wireless parameter needs to update in above-mentioned steps 404, the most also may be used To trigger macro base station wireless parameter renewal process.

405b, 406b, 407b in above-mentioned steps and 302,303,304 in embodiment three step In be consistent；It it is all the process of SON server triggers base station wireless parameter renewal.

Above-mentioned steps is also applied for the renewal base station Neighboring Cell List process of base station triggers.

Above-mentioned steps is also applied for other type of base station (macro base station, micro-base station, femto base station etc.) and triggers Update wireless parameter process.

Embodiment five

Embodiment five refers to that base station reports the stream of performance (mainly including wireless performance) to SON server Journey schematic diagram.
