The update method of a kind of neighbor cell list of home base station and wireless parameter

The cross reference of related application

The application divides an application.The application number of original application is 200910175000.4, and the applying date is on October 27th, 2009, and denomination of invention is " update method of a kind of neighbor cell list of home base station and wireless parameter ".

Technical field

The present invention relates to communication field, relate in particular to the update method of a kind of neighbor cell list of home base station and wireless parameter.

Background technology

The general deployment of existing Radio Access Network is all macro base station, and it is large that macro base station has area coverage, can support high speed mobile terminal characteristic; But because macro base station throughput is certain, although its area coverage is large, but the actual number of users that can simultaneously access is limited, and the bandwidth of macro base station need to be in numerous shared among users, therefore the bandwidth that actual user obtains might not be very desirable, especially when traffic is busier.Consider user's large portion time or office at home, and move in low speed, there is high bandwidth requirements, therefore in wireless technology, introduce Home eNodeB and become study hotspot, Home eNodeB is at micro-wave access global inter communication (Worldwide Interoperability for Microwave Access, abbreviation WiMAX) in system, be called Femto or WiMAX home base station access point (WiMAX Femto Access Point is called for short WFAP).

The feature of Home eNodeB is that coverage is little, is only minority Terminal Service, and utilizes the existing broadband connection access to family base station of user IAD, and obviously, the terminal of access to family base station can access high-bandwidth service.

Home eNodeB can be divided into three types: private type (CSG-Closed Model, CSG is Closed Subscribers Group), publicly-owned type (Open Model), mixed type (CSG-Open Model); .So-called private type is exactly only to particular terminal or user, to provide service; Publicly-owned type is exactly the same with macro base station, to the terminal of access or not restriction of user; Mixed type is exactly to the terminal of access or not restriction of user, but particular terminal or user is provided to the service of high priority.

Because Home eNodeB number is numerous, traditional macro base station management method is not exclusively applicable, but adopts self-organizing network (Self-Organized Network is called for short SON) method to manage; To Home eNodeB, adopt self-organized network management to relate generally to the parameter to eating dishes without rice or wine to relate to, for example, to radio frequency (Radio Frequency, be called for short RF) parameter, physical layer (Physical Layer, be called for short PHY) self-organizing network parameter, the management of media access control layer (Media Access Control is called for short MAC) parameter.The method of self-organized network management mainly comprises three parts: self-configuring (Self-Configuration), self-optimizing (Self-Optimization), self-healing (Self-Healing).

Self-configuring is mainly that Home eNodeB carries out in initialization procedure at access band or start, obtains the initial configuration parameter of eating dishes without rice or wine to relate to, the most important Neighboring Cell List that comprises in these parameters.For example WFAP is 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 Neighboring Cell List, and the Home eNodeB that can be operated in around terminal pattern scanning obtains Home eNodeB list; The adjacent area femtocell information wherein obtaining by scanning also needs to be synchronized to SON server, so that the topology information of the whole network of SON system real-time servicing.Home eNodeB just obtains its Neighboring Cell List at initialization procedure like this, comprising the information of adjacent area macro base station and Home eNodeB.

Self-optimizing refers to that Home eNodeB is in providing the process of service, according to the information gathering, to the parameter adjustment of eating dishes without rice or wine, to realize capacity and coverage optimization, mobile management optimization, reduces interference optimization.

When self-healing refers to that Home eNodeB breaks down or can not provide satisfactory service, by self-organized network management method, automatically fixed a breakdown, or fault effects is reduced to minimum.

In self-optimizing process, also comprise adjacent area Automatic Optimal; Although in Home eNodeB initialization procedure, Home eNodeB can obtain initial neighboring BS information, but after this owing to breaking down in network topology change or base station, or adjacent area list information is imperfect in initialization procedure, all need follow-uply by Neighboring Cell List self-optimizing, to carry out real-time update adjacent area list information.Neighboring Cell List upgrades automatically to guaranteeing that whole net performance of handoffs is even more important, and is also that handover optimization is relevant.

In WiMAX Forum, Home eNodeB is just discussed to the automatic configuration in Home eNodeB initialization procedure at present, also do not relate to Neighboring Cell List and automatically upgrade.In addition, WiMAX Forum is not discussed at present wireless parameter yet (handoff parameter for example, is covered and capacity interference parameter etc.; Wherein handoff parameter refers to that triggering terminal scans, reports the threshold value of scanning result, initiation handover request, and serving BS is initiated to the threshold value that target BS switches) after initial configuration, the flow process of how to carry out self-optimizing.

Embodiment

In Home eNodeB, preserve the information of the Neighboring Cell List of self, preserve network topology structure information in SON server, this topology information comprises the information of the neighboring BS relationship between the base station that SON server manages.

No matter be the Neighboring Cell List of preserving in Home eNodeB, or in the whole network preserved of SON server, the neighboring BS relationship between base station all relate to the information of neighbor base station.What in the Neighboring Cell List that Home eNodeB is preserved, deposit is the information of the neighbor base station that can be switched to from this Home eNodeB, this neighbor base station can be macro base station, also can be other Home eNodeB, can also be those coverages in the base station of macro base station and inter-household other type.These neighbor base stations can belong to same operator (NAP or NSP) with this Home eNodeB, also can belong to different operators (NAP or NSP), and different neighbor base stations also can belong to different operators (NAP or NSP).Base station information in Neighboring Cell List at least comprises one of following information: base station identification information, frequency information, operator's sign, with the commercial relations of current base station, operating state, whether allow to switch, whether allow to delete, whether allow access etc.Wherein, with the commercial relations of current base station, refer between this neighbor base station and the operator of current base station whether have commercial relations, if existed, represent that current base station can be switched to neighbor base station, otherwise can not be switched to neighbor base station; Wherein operating state can be further subdivided into the operating state of base station self, and the operating state of the network being connected with this base station.Wherein base station type one of comprises as follows at least: macro base station, micro-base station, femto base station, Home eNodeB; Wherein Home eNodeB type at least comprises one of following: private type, publicly-owned type, mixed type.Show that base station type has following object one of at least: during switching, can allow terminal preferably be switched to Home eNodeB and be served; The base station that can know which private type due to serving BS allows access, therefore can avoid terminal not allow the private base station of its access to switch in adjacent area; The reason of the operating state that comprises base station is, if neighbor base station is not in running order, can avoid terminal to switch to these base stations; Not allowing to delete, may be the requirement of operator, need to retain its syntople; Not allowing to switch, may be operator, does not allow the switching between some base station, may be also that base station is not in running order, or at full capacity etc.

Wherein, base station identification information at least comprises one of following information: base station MAC layer sign (BS ID), prefix index, cell ID (Cell ID).

Neighboring BS relationship between base station is generally followed mutual equipping rules, and base station A is if the adjacent area of base station B, and base station B is also the adjacent area of base station A so; When base station A adds to base station B in its Neighboring Cell List, perhaps base station B adds base station A in its Neighboring Cell List to so; When base station A deletes base station B from its Neighboring Cell List, base station B also needs base station A to delete from its Neighboring Cell List so.

When Home eNodeB obtains after initial neighboring BS information in initial network entry, its Neighboring Cell List may also need to upgrade.Adjacent-area list renewing comprises that following situation one of at least: in Neighboring Cell List, increase base station and information thereof, delete base station and information thereof in Neighboring Cell List, the base station information in Neighboring Cell List needs to upgrade.

The renewal of the Neighboring Cell List of Home eNodeB thus Home eNodeB oneself triggers, also can be by SON server triggers.Below by two embodiment, both of these case is described respectively.

Embodiment mono-:

In embodiment mono-, describe SON server and initiate the flow process of base station adjacent-area list renewing.SON server detects base station Neighboring Cell List need to upgrade time, upgrades the neighboring BS relationship between the base station of the whole net of self preserving, and its Neighboring Cell List is upgraded in the base station that indication need to be upgraded Neighboring Cell List.The base station that Neighboring Cell List need to upgrade can be with one of Types Below: macro base station, micro-base station, femto base station (Pico), Home eNodeB.

The present invention can be typically applied in the situation that Home eNodeB upgrades its Neighboring Cell List.Below with reference to Fig. 1, illustrate SON server and initiate the method that neighbor cell list of home base station upgrades, specifically comprise the following steps:

Step 101, SON server detects neighbor cell list of home base station to be needed to upgrade;

During the network topology structure information of its preservation of SON server update, or SON server is when doing the mutual configuration inspection in adjacent area, and whether neighbor cell list of home base station can be detected needs to upgrade.SON server can be known the state (for example can know whether in running order base station, base station) of base station in whole network, also can know base station situation newly-increased in network or that delete.

SON server judges while following situation being detected that neighbor cell list of home base station needs to upgrade:

(1) base station information of the base station in Neighboring Cell List changes.Comprise that base station changes to non operating state from operating state, cause that the reason of base station in non operating state may be that the link that is linked to base station breaks down, break down in base station itself, power-off of base station, base station shutdown etc.; Now need to upgrade the base station information of this base station in Neighboring Cell List.

(2) newly-increased certain base station.This newly-increased base station and information thereof now need to be added near the base station that can be used as base station, Home eNodeB adjacent area increasing newly Home eNodeB in Neighboring Cell List.In addition,, for newly-increased base station, whether the neighbor base station that the inspection of SON server is newly-increased and current base station there are commercial relations; If self can not check SON server, can be by for example, cooperation checks with other network element (, network management system, AAA etc.).

(3) delete certain base station.Base station near the Qie family station list removing Home eNodeB, now needs to delete this base station and information thereof in Neighboring Cell List.

SON server detects base station information in neighbor cell list of home base station need to upgrade time or receive that neighbor cell list of home base station upgrades after the information of result (success), upgrades the neighboring BS relationship of base station in the network of self preservation.

Step 102, SON server sends the indication information with adjacent-area list renewing information to the Home eNodeB that need to upgrade Neighboring Cell List, notifies this Home eNodeB to upgrade Neighboring Cell List;

The adjacent-area list renewing information that SON server sends to Home eNodeB at least comprises one of following information: the neighbor base station and the information thereof that in Neighboring Cell List, need increase; In Neighboring Cell List, need neighbor base station and the information thereof of deleting; The lastest imformation of the base station information of base station in Neighboring Cell List.

Owing to preserving the positional information of Femto in SON server, if while therefore increasing macro base station newly in network, SON service is according under the known newly-increased macro base station coverage of topological structure or have a Femto of overlapping covering relation so, therefore SON server can know that the in running order macro base station newly adding can be used as the adjacent area of which Femto, thereby trigger relevant Femto, increases the information of this macro base station in its Neighboring Cell List.This process is also applicable to trigger relevant macro base station increases the information of this macro base station in its Neighboring Cell List.In addition,, in Home eNodeB initialization procedure, Home eNodeB can send relevant information in initialization procedure to Home eNodeB management system and/or self-organizing network server; If Home eNodeB only sends described information to Home eNodeB management system, Home eNodeB management system also needs described information to send to self-organized network management server.By said process self-organizing network server, learned and in network, increased newly one family base station, and according to the position relationship in network topology, determining needs to increase described Home eNodeB and information thereof in the Neighboring Cell List of which Home eNodeB.

Because SON server is preserved the neighboring BS relationship of base station in network, therefore in network, delete certain base station when (comprising macro base station or Femto), SON server can know that the Neighboring Cell List of which base station (macro base station or Femto) is affected, thereby trigger the affected base station of Neighboring Cell List, deletes the information of described deletion base station from its Neighboring Cell List.In addition,, at Home eNodeB shutdown or off-grid or from net or exit in process, Home eNodeB can send shutdown or off-grid or from net, or the relevant information exiting is to Home eNodeB management system and/or self-organizing network server; If Home eNodeB only sends described information to Home eNodeB management system, Home eNodeB management system also needs described information to send to self-organized network management server.By said process self-organizing network server, learn that shutdown or off-grid have appearred in Home eNodeB described in network or from net, or exit, and according to the position relationship in network topology, determining needs to delete described Home eNodeB and information thereof in the Neighboring Cell List of which Home eNodeB, or in Neighboring Cell List, needs to upgrade the information of described Home eNodeB.

SON server can real-time detection network in the operating state of base station (comprising macro base station or Femto), when SON discovering server base station is changed to non operating state from operating state, obviously should can not be used as the target BS switching in the base station in non operating state; Therefore need to from the Neighboring Cell List of relevant base station, delete the neighbor base station in non operating state, or this base station of mark is in non operating state in Neighboring Cell List, or this base station of mark can not be for the target BS switching in Neighboring Cell List.

Because SON server is preserved the neighboring BS relationship of base station in network, therefore when SON server detects certain base station in network (comprising macro base station or Femto) and is changed to non operating state from operating state, SON server can know that the Neighboring Cell List of which base station (comprising macro base station or Femto) is affected, thereby trigger the affected base station of Neighboring Cell List and upgrade its Neighboring Cell List, to the base station (comprising macro base station and Home eNodeB) that comprises this base station in Neighboring Cell List, send Indication message, indicate it to upgrade Neighboring Cell List; And carry at least one in following information in the information sending to the base station (comprising macro base station and Home eNodeB) that comprises this base station in Neighboring Cell List: from Neighboring Cell List, delete the base station information in non operating state; Or the operating state of upgrading this base station in Neighboring Cell List is non operating state, or the information of upgrading this base station from Neighboring Cell List is for can not be as the target BS switching, or the information of upgrading this base station from Neighboring Cell List is for can not be as the base station of access.In addition, when changing, Home eNodeB operating state (and changes to non operating state from operating state, and from non operating state, return to operating state etc.), Home eNodeB can send the information of the work state information that carries Home eNodeB to self-organizing network server and/or Home eNodeB management system; If Home eNodeB only sends described information to Home eNodeB management system, Home eNodeB management system also needs described information to send to self-organized network management server.By said process self-organizing network server, learn that the operating state of described Home eNodeB changes, and according to the position relationship in network topology, determining needs to delete described Home eNodeB and information (while changing to non operating state from operating state) or newly-increased described Home eNodeB and information (while returning to operating state from non operating state) thereof in the Neighboring Cell List of which Home eNodeB, or the base station information that needs to upgrade described Home eNodeB in Neighboring Cell List (upgrades the operating state of Home eNodeB described in Neighboring Cell List, or the operating state of further renewal and Home eNodeB self).When changing, uses other base station information that this process is also applicable to Home eNodeB; This process is also applicable to the base station of other type.

In addition, when changing, the connected network operating state of certain Home eNodeB (and changes to malfunction from operating state, and from malfunction, return to operating state etc.), Home eNodeB and/or self-organizing network server and/or Home eNodeB management system detect network operating state and change; But when network changes to malfunction from operating state, Home eNodeB may not report this fault to self-organizing network server or Home eNodeB management system.When self-organizing network server self can not detect the connected network operating state of described Home eNodeB and changes, self-organizing network service can learn that the connected network operating state variation of described Home eNodeB (comprises that Home eNodeB sends described information to self-organizing network server by Home eNodeB or Home eNodeB management system, Home eNodeB management system sends described information to self-organizing network server, and Home eNodeB sends described information to Home eNodeB management system, then Home eNodeB management system sends to self-organizing network server by described information again), and according to the position relationship in network topology, determining needs to delete described Home eNodeB and information (while changing to malfunction from operating state) or newly-increased described Home eNodeB and information (while returning to operating state from malfunction) thereof in the Neighboring Cell List of which Home eNodeB, or the information that needs to upgrade described Home eNodeB in Neighboring Cell List (is upgraded the operating state of Home eNodeB described in Neighboring Cell List, or the operating state of the network that further renewal is connected with Home eNodeB).This process is also applicable to the base station of other type.

Step 103, Home eNodeB is received after the information described in step 102, upgrades its Neighboring Cell List;

Step 104, Home eNodeB sends the information of the renewal result of this Home eNodeB of indication to SON server, notify the result of its renewal of SON server.The result that Home eNodeB carries out adjacent-area list renewing is successfully or failure.

In said method, SON server is before Home eNodeB sends the information of upgrading its Neighboring Cell List or after receiving adjacent-area list renewing result (success) information of Home eNodeB transmission, the neighboring BS relationship that upgrades base station in its network topology structure information (is that Home eNodeB has increased neighbor base station newly, or deleted neighbor base station, or the base station information of its neighbor base station changes), so just can make SON server preserve in the Neighboring Cell List of neighboring BS relationship same family base station Information preservation consistent.

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

Specific embodiment three:

When SON detects certain base station and is changed to non operating state from operating state, can there be two kinds of processing methods.

Method one: same processing, as deleting base station scenario, is done in this base station, and the network topology result that SON preserves according to self, knows the Neighboring Cell List that has influence on which base station in this base station of non operating state.Upgrade on the one hand neighboring BS relationship between the base station in the network of self preserving, also send message to affected base station, be used to indicate and from its Neighboring Cell List, delete this not in running order base station information simultaneously.

The network topology result that method two: SON preserves according to self, knows that this has influence on the Neighboring Cell List of which base station in this base station of non operating state; Upgrade on the one hand neighboring BS relationship between the base station in the network of self preserving, this base station state of mark is non operating state, and/or this base station of mark can not be for switching, and/or this base station of mark can not be for access.Simultaneously also send message to affected base station, be used to indicate and from its Neighboring Cell List, upgrade this base station information, not in running order for showing this base station, and/or can not be for, and/or can not be for access.

Embodiment bis-:

In embodiment bis-, describe Home eNodeB and initiate the flow process of adjacent-area list renewing.As example, base station A is macro base station or Femto, and base station B is macro base station or Femto.As shown in Figure 2, comprise following steps:

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

Base station can detect neighbor base station and the information thereof not comprising in existing Neighboring Cell List, detects new neighbor base station and the information thereof that can increase newly in its Neighboring Cell List.

Base station can be found the adjacent area not comprising in current Neighboring Cell List in the following way: 1. the message of the terminal to report by its service is found, terminal to report message at least comprises one of following message: scanning result report message, handover request message, switch indicating information.In these message, there is the neighbor base station not comprising in Neighboring Cell List, can think that base station detected new neighbor base station by terminal to report message.2. Home eNodeB is found new neighbor base station in follow up scan neighbor base station process.3. base station (comprising Home eNodeB) is detected by uncontrolled switching or unpredictable handover event; And the message that uncontrolled switching and unpredictable switching are the requesting terminal information that sends by target BS is known.

Base station may also have alternate manner to detect neighbor base station in Neighboring Cell List can not, as neighbor base station, need to delete certain neighbor base station from Neighboring Cell List.

Home eNodeB detects situation that the base station information in Neighboring Cell List changes and at least comprises a kind of in following situation: in Neighboring Cell List, need to increase neighbor base station and information thereof; Or in Neighboring Cell List, need to delete neighbor base station and information thereof; Or in Neighboring Cell List, need to upgrade the base station information of neighbor base station.

If WFAP detects Neighboring Cell List while changing, Home eNodeB can directly upgrade its Neighboring Cell List or wait for that SON sends and upgrade the Neighboring Cell List of himself after Indication message again.

Step 202, Home eNodeB A sends the indication information with adjacent-area list renewing information to SON server, the Neighboring Cell List of Home eNodeB described in update notifications;

The lastest imformation of the Neighboring Cell List that Home eNodeB A sends to SON server at least comprises one of following information: newly-increased neighbor base station and information thereof; Neighbor base station and the information thereof of deleting; The lastest imformation of base station information.

Step 203, SON server is received after the information of Home eNodeB A transmission, sends the confirmation of receiving this information to this Home eNodeB A;

This step 203 is optional step.

Step 204, SON server carries out verification to receiving the lastest imformation of Neighboring Cell List, and detect and need to carry out the base station (comprising macro base station and Home eNodeB) of adjacent-area list renewing, and upgrade the neighboring BS relationship of base station (comprising macro base station and Home eNodeB) in the network of self preserving;

SON server carries out verification to receiving the lastest imformation of Neighboring Cell List, refers to that SON service can check whether newly-increased neighbor base station and current base station exist commercial relations; If SON server self can not verification, can by and other network element (for example, network management system, AAA etc.) cooperation carry out verification.

The base station that need to carry out adjacent-area list renewing that SON server detects can be a plurality of base stations, and the base station that need to carry out adjacent-area list renewing can be macro base station, can be Home eNodeB, can also be macro base station and Home eNodeB.

SON server upgrades the neighboring BS relationship of base station in network according to the information of receiving; In addition, SON server finds according to this information whether the neighboring BS relationship of other base station is affected (according to adjacent area interworking, putting or other method), if there is affected other base station of neighboring BS relationship, SON server also will notify other base stations to upgrade its Neighboring Cell List.

The Home eNodeB that need to carry out adjacent-area list renewing at least comprises one of following base station: to described self-organizing network server, send the Home eNodeB of indication information, the newly-increased neighbor base station comprising in the indication information sending to described self-organizing network server; The neighbor base station of the deletion comprising in the indication information sending to described self-organizing network server; According to adjacent area interworking, put the Home eNodeB that need that check table detects upgrade Neighboring Cell List.

While needing to carry out the Home eNodeB of information updating in SON server detection Neighboring Cell List, also consider mutual equipping rules.For example, base station A detects newly-increased adjacent area B, and SON server is received after this information so, be not only base station A and need to increase adjacent area B newly, and base station B also needs newly-increased adjacent area A.Base station A detects and need to delete adjacent area B, and SON server is received after this information so, be not only base station A and need to delete adjacent area B, and base station B also needs to delete adjacent area A.

Step 205a/205b, SON server sends the indication information with adjacent-area list renewing information to the base station (can be macro base station and/or Home eNodeB) that need to carry out adjacent-area list renewing;

The Home eNodeB that needs to carry out information updating in Fig. 2 is base station A and base station B, is only used as example, and in actual applications, the Home eNodeB that need to carry out information updating can have a plurality of.In the drawings, send to Home eNodeB A(base station A to send adjacent-area list renewing request message to the base station of SON server) message be adjacent-area list renewing response message, sending to B(base station, base station B is in the time need to upgrading the Neighboring Cell List of base station A, and its Neighboring Cell List is affected base station also) message be adjacent-area list renewing request message.

The information that is used to indicate adjacent-area list renewing at least comprises one of following information: in Neighboring Cell List, increase neighbor base station and information thereof, or in Neighboring Cell List, delete neighbor base station and information thereof, or in Neighboring Cell List, upgrade the base station information of certain neighbor base station.

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

Its Neighboring Cell List of described renewal comprises a kind of in following update mode: in Neighboring Cell List, increase neighbor base station and information thereof, delete neighbor base station and information thereof in Neighboring Cell List, upgrade the base station information of neighbor base station in Neighboring Cell List.

Step 207a/207b, Home eNodeB A and Home eNodeB B send to SON server the information that result is upgraded in indication.

The result of adjacent-area list renewing be successfully or failure.

Step 207a/207b is optional step.

In said method, before the base station that SON server need to upgrade to Neighboring Cell List in transmission information or after receiving that the information of result is upgraded in base station, SON server self upgrades the neighboring BS relationship between base station in network and (comprises that base station has increased neighbor base station newly, or base station deleted neighbor base station, or the neighbor base station information of base station changes); Make SON server preserve neighboring BS relationship consistent with the Information preservation in the Neighboring Cell List of base station.

It is one of following constantly that himself Neighboring Cell List is upgraded in base station: base station is detected in the time of need to upgrading its Neighboring Cell List, and its Neighboring Cell List is directly upgraded in base station; Or base station is received after the information of its Neighboring Cell List is upgraded in the indication of SON server and is upgraded its Neighboring Cell List again.

If macro base station Neighboring Cell List is surveyed in SON service in above-mentioned steps 204, need to upgrade, can also trigger macro base station adjacent-area list renewing process.

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

Above-mentioned steps is also applicable to the process of the Neighboring Cell List of other type of base station (macro base station, micro-base station etc.) triggering.

When Home eNodeB obtains after initial wireless parameter information in initial network entry, its wireless parameter may also need to upgrade.The renewal of the wireless parameter of Home eNodeB thus Home eNodeB oneself triggers, also can be by SON server triggers.Below by two embodiment, both of these case is described respectively, the switching-related parameters of usining especially upgrades as example.

Embodiment tri-:

In embodiment tri-, describe SON server and initiate the flow process that base station wireless parameter upgrades.SON server detects wireless parameter need to upgrade after, indication need to be upgraded the base station of wireless parameter and upgrade its wireless parameter.The base station that need to upgrade wireless parameter can be with one of Types Below: macro base station, micro-base station, femto base station (Pico), Home eNodeB.

It is the situation of Home eNodeB that the present invention can be typically applied in the base station that wireless parameter need to upgrade.Below with reference to Fig. 3, illustrate SON server and initiate the method that Home eNodeB wireless parameter upgrades, specifically comprise the following steps:

Step 301, SON server detects Home eNodeB wireless parameter to be needed to upgrade;

Base station gathers the relevant performance parameter of wireless parameter, and reports to SON server.SON server is according to gathering the relevant performance parameter of wireless parameter, and analyzes these performance parameters, for example performance of handoffs, call features, capacity and covering correlated performance, interference correlation energy; When these performances do not meet the demands, (for example do not compare with certain threshold value), which wireless parameter SON server can be analyzed and need to upgrade and recommend new value to improve this performance.In addition after wireless parameter has been done and reshuffled, also need to trigger the wireless parameter that upgrades affected Home eNodeB.

For example, for performance of handoffs, comprise and switch too early, switched evening, ping-pong etc., if these events acquire a certain degree (number or percentage), SON server can trigger the handoff parameter that upgrades Home eNodeB and improves performance of handoffs, these handoff parameters comprise: the thresholding that the thresholding of triggering terminal scanning, the thresholding that triggering terminal reports scanning result, triggering terminal are initiated handover request, and serving BS is initiated to the thresholding of target BS switching etc.

For example, for covering performance, may relate to the maximum transmission power parameter of Home eNodeB;

For example, for interference free performance, may relate to the maximum transmission power parameter of Home eNodeB;

Step 302, SON server sends the first information with wireless parameter lastest imformation (i.e. config update request message in figure to the Home eNodeB that need to upgrade wireless parameter, wherein carry the lastest imformation of wireless parameter), notify this Home eNodeB to upgrade its wireless parameter, carry the lastest imformation of wireless parameter;

With handoff parameter, be updated to example, if SON server is surveyed or known that switching too early too much, may need to improve the threshold value of switching-related parameters, SON server can be notified Home eNodeB this lastest imformation so.

Step 303, Home eNodeB is received after the first information described in step 302, upgrades wireless parameter;

Step 304, Home eNodeB sends second information (the configuration response message in figure, carries in message and upgrade object information) of the wireless parameter renewal result of this Home eNodeB of indication to SON server, notify the result of its renewal of SON server.The result that Home eNodeB carries out wireless parameter renewal is successfully or failure.

In said method, before SON server sends the first information to Home eNodeB, or receive (representing that Home eNodeB upgrades wireless parameter success) after the second information that Home eNodeB sends, SON server update self is preserved the wireless parameter of this Home eNodeB.

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

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

With switching-related parameters, be updated to example:

Specific embodiment one:

When SON learns certain base station too early event that switches, reach threshold value (for example surpass some, or reach certain percentage), may improve thresholding that MS initiates handover request, improve the thresholding etc. that serving BS is switched to target BS.

Specific embodiment two:

When SON learns certain base station late event that switched, reach threshold value (for example surpass some, or reach certain percentage), may reduce thresholding that MS initiates handover request, reduce the thresholding etc. that serving BS is switched to target BS.

Specific embodiment three:

When SON learns certain region ping-pong, reach frequent generation (for example surpass some, or reach certain percentage), may adjust the relevant handoff threshold value of relevant base station, this region.

Embodiment tetra-:

In embodiment tetra-, describe Home eNodeB and initiate the flow process that wireless parameter upgrades.Base station A is macro base station or Femto, and base station B is macro base station or Femto.As shown in Figure 4, comprise following steps:

Step 401, base station A detects its wireless parameter informational needs and upgrades;

Base station gathers the relevant performance parameter of wireless parameter, and these performances are including, but not limited to following performance: performance of handoffs, call features, capacity and covering correlated performance, interference correlation can etc.; Whether base station, except these performance relevant parameters being reported to SON server, self also can be analyzed with these performance relevant parameters and need to upgrade; For example, when above-mentioned these Key Performance Indicators (KPI, Key Performance Indication) are while reaching certain thresholding, which wireless parameter base station can be analyzed and need to upgrade and recommend new value to improve this performance.

For example, for performance of handoffs, comprise and switch too early, switched evening, ping-pong etc., if these events acquire a certain degree (number or percentage), base station can be triggered and be upgraded performance of handoffs relevant parameter and improve performance of handoffs, these switching-related parameters comprise: the threshold value of triggering terminal scanning, the threshold value that triggering terminal reports scanning result, terminal are initiated the threshold value of handover request, and serving BS is initiated to the threshold value of target BS switching etc.

If WFAP is through performance evaluation, in the time of need to upgrading its wireless parameter, Home eNodeB can directly upgrade its wireless parameter or wait for after SON sends indication information and upgrade its wireless parameter again.
