Description

The update method of tabulation of a kind of Home eNodeB adjacent area and wireless parameter

Technical field

The present invention relates to communication field, relate in particular to the update method of tabulation of a kind of Home eNodeB adjacent area and wireless parameter.

Background technology

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

The characteristics of Home eNodeB are that coverage is little, are the minority Terminal Service only, and utilize the user to have broadband connection access to family base station IAD now, 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 are Closed Subscribers Group), publicly-owned type (Open Model), mixed type (CSG-Open Model); So-called private type is exactly service to be provided only for particular terminal or user; Publicly-owned type is exactly the same with macro base station, to the terminal that inserts or user without limits; Mixed type is exactly to the terminal that inserts or user without limits, but particular terminal or user is provided the service of high priority.

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

Self-configuring mainly is that Home eNodeB carries out in the 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 (server refers to network management system here from network side server, perhaps realize the server of SON function) obtain its macro base station Neighboring Cell List, and the Home eNodeB that can be operated in around the terminal pattern scanning obtains the Home eNodeB tabulation; Wherein the adjacent area femtocell information that obtains by scanning also needs to be synchronized to the 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 Home eNodeB in the process of service is provided, according to the information of gathering, to the parameter adjustment of eating dishes without rice or wine, so that realization capacity and coverage optimization, mobile management optimization reduce interference optimization.

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

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

At present in the WiMAX Forum Home eNodeB is just discussed automatic configuration in the Home eNodeB initialization procedure, also do not relate to Neighboring Cell List and upgrade automatically.In addition, WiMAX Forum is not discussed wireless parameter at present yet (handoff parameter is for example covered and capacity interference parameter etc.; Wherein handoff parameter is meant that triggering terminal scans, reports the threshold value of scanning result, initiation handoff 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

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

No matter be the Neighboring Cell List of preserving in the Home eNodeB, or the neighboring BS relationship between the base station all relate to the information of neighbor base station in the whole network preserved of SON server.What deposit in the Neighboring Cell List that Home eNodeB is preserved is the information of the neighbor base station that can switch to from this Home eNodeB, this neighbor base station can be a 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 the Neighboring Cell List comprises one of following information at least: 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 deletion, whether allow to insert etc.Wherein with the commercial relations of current base station, be meant between the operator of this neighbor base station and current base station whether have commercial relations, if exist, represent that then current base station can switch to neighbor base station, otherwise can not switch to neighbor base station; Wherein operating state can further be subdivided into the base station self working state, and the operating state of the network that links to each other with this base station.Wherein base station type comprise following one of at least: macro base station, little base station, femto base station, Home eNodeB; Wherein the Home eNodeB type comprises one of following at least: private type, publicly-owned type, mixed type.Show that base station type has following purpose one of at least: during switching, can allow terminal preferably switch to Home eNodeB and obtain service; Because serving BS can be known the base station of which private type and allow to insert, and therefore can avoid terminal not allow the private base station of its access to switch in the adjacent area; The reason that comprises the operating state of base station is, if neighbor base station is not in running order, then can avoid terminal to switch to these base stations; Not allowing deletion, may be the requirement of operator, needs to keep its syntople; Not allowing to switch, may be operator, does not allow the switching between some base station, also may be that the base station is not in running order, perhaps at full capacity etc.

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

Neighboring BS relationship between the base station is generally followed interworking and is put principle, and promptly base station A is if the adjacent area of base station B, and base station B also is the adjacent area of base station A so; Promptly when base station A added to base station B in its Neighboring Cell List, perhaps base station B added base station A in its Neighboring Cell List to so; When base station A deleted base station B from its Neighboring Cell List, base station B also needed base station A is deleted from its Neighboring Cell List so.

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

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

Embodiment one:

Describe the SON server among the embodiment one and initiate the flow process of base station adjacent-area list renewing.The SON server detects the base station Neighboring Cell List need upgrade the time, upgrade 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 needs to upgrade Neighboring Cell List.The base station that Neighboring Cell List need upgrade can be one of following type: macro base station, little 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, specify the method that the SON server is initiated the Home eNodeB adjacent-area list renewing, specifically may further comprise the steps:

Step 101, SON server detect the tabulation of Home eNodeB adjacent area to be needed to upgrade;

During the network topology structure information of its preservation of SON server update, perhaps, the SON server is put when checking doing the adjacent area interworking, and whether can detect the tabulation of Home eNodeB adjacent area needs to upgrade.Whether in running order the SON server can know the state (for example can know base station, base station) of base station in the whole network, also can know the base station situation of newly-increased or deletion in the network.

When detecting following situation, the SON server judges that the tabulation of Home eNodeB adjacent area needs to upgrade:

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

(2) newly-increased certain base station.Near the base station that can be used as base station, Home eNodeB adjacent area that increases newly Home eNodeB, need add in Neighboring Cell List this moment should newly-increased base station and information thereof.In addition, for newly-increased base station, whether newly-increased neighbor base station and the current base station of SON server inspection exists commercial relations; If self can not check the SON server, can check by cooperating with other network element (for example, network management system, AAA etc.).

(3) delete certain base station.In near remove the Home eNodeB and base station in family's station list, need this base station of deletion and information thereof in Neighboring Cell List this moment.

The SON server detects base station information in the Home eNodeB adjacent area tabulation need upgrade the time or after receiving Home eNodeB adjacent-area list renewing result's (success) information, upgrades the neighboring BS relationship of base station in the network of self preservation.

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

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

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

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

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

Because the SON server is preserved the neighboring BS relationship of base station in the network, therefore detect certain base station in the network (comprising macro base station or Femto) when operating state is changed to non operating state when the SON server, the 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, the base station (comprising macro base station and Home eNodeB) that comprises this base station in Neighboring Cell List sends Indication message, indicates it to upgrade Neighboring Cell List; And carry in the following information at least one in the information that the base station (comprising macro base station and Home eNodeB) that comprises this base station in Neighboring Cell List sends: deletion is in the base station information of non operating state from Neighboring Cell List; The operating state of perhaps upgrading this base station in Neighboring Cell List is a non operating state, the information of perhaps upgrading this base station from Neighboring Cell List is can not be as the target BS that switches, and the information of perhaps upgrading this base station from Neighboring Cell List is can not be as the base station of inserting.In addition, when changing, family's base station operating state (and changes to non operating state from operating state, and return to operating state etc. from non operating state), 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 the Home eNodeB management system, the Home eNodeB management system also needs described information is sent to the self-organizing network management server.The operating state of learning described Home eNodeB by said process self-organizing network server changes, and concern according to the position in the network topology, determine to need to delete in the Neighboring Cell List of which Home eNodeB described Home eNodeB and information thereof (when operating state changes to non operating state) or newly-increased described Home eNodeB and information thereof (when non operating state returns to operating state), perhaps need to upgrade the base station information (upgrade the operating state of Home eNodeB described in the Neighboring Cell List, or further upgrade and the Home eNodeB self working state) of described Home eNodeB in the Neighboring Cell List.This process also is applicable to when other base station information of Home eNodeB changes and uses; This process also is applicable to the base station of other type.

In addition, when changing, the network work state that links to each other of certain Home eNodeB (and changes to malfunction from operating state, and return to operating state etc. from malfunction), Home eNodeB and/or self-organizing network server and/or Home eNodeB management system detect the network work state and change; But when network when operating state changes to malfunction, Home eNodeB may not report this fault to give self-organizing network server or Home eNodeB management system.When self-organizing network server self can not detect the network work state variation that described Home eNodeB links to each other, the self-organizing network service can learn that the continuous network work state variation of described Home eNodeB (comprises that Home eNodeB sends described information to the self-organizing network server by Home eNodeB or Home eNodeB management system, the Home eNodeB management system sends described information to the self-organizing network server, and Home eNodeB sends described information to the Home eNodeB management system, the Home eNodeB management system sends to the self-organizing network server with described information more then), and concern according to the position in the network topology, determine to need to delete in the Neighboring Cell List of which Home eNodeB described Home eNodeB and information thereof (when operating state changes to malfunction) or newly-increased described Home eNodeB and information thereof (when malfunction returns to operating state), perhaps need to upgrade the information (upgrade the operating state of Home eNodeB described in the Neighboring Cell List, or further upgrade the operating state of the network that links to each other with Home eNodeB) of described Home eNodeB in the Neighboring Cell List.This process also is applicable to the base station of other type.

Step 103, Home eNodeB are upgraded its Neighboring Cell List after receiving the described information of step 102;

Step 104, Home eNodeB are promptly notified the result of its renewal of SON server to the renewal result's of this Home eNodeB of SON server transmission indication information.The result that Home eNodeB carries out adjacent-area list renewing is successfully or fails.

In the said method, the SON server is before the information of its Neighboring Cell List of Home eNodeB transmission renewal 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), could make the SON server preserve that information is consistent in the Neighboring Cell List of neighboring BS relationship same family base station like this.

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

Specific embodiment one:

When SON detected certain base station of deletion, SON knew that according to the network topology structure of self preserving this base station of deletion has influence on the Neighboring Cell List of which base station; Upgrade neighboring BS relationship between the base station in the network of self preserving on the one hand, also send information to affected base station simultaneously, be used for indication from its this base station information of Neighboring Cell List deletion.

Specific embodiment two:

When SON detected certain base station of increase, SON knew that according to the network topology structure of self preserving this base station of increase has influence on the Neighboring Cell List of which base station; Upgrade neighboring BS relationship between the base station in the network of self preserving on the one hand, also send message to affected base station simultaneously, being used for indication increases this base station information from its Neighboring Cell List.

Specific embodiment three:

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

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

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

Embodiment two:

Describe Home eNodeB among the embodiment two 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 the Neighboring Cell List needs to upgrade;

The base station can detect neighbor base station and the information thereof that does not comprise in the existing Neighboring Cell List, promptly detects the new neighbor base station and the information thereof that can increase newly in its Neighboring Cell List.

The base station can be found the adjacent area that do not comprise in the current Neighboring Cell List in the following way: 1. the message of the terminal to report by its service finds that terminal to report message comprises one of following message at least: scanning result report message, handoff request message, switch indicating information.The neighbor base station that do not comprise in the Neighboring Cell List in these message, occurred, can think that then the 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 uncontrolled switching and unpredictable switching to be the message of the requesting terminal information that sends by target BS know.

The base station may also have alternate manner to detect in the Neighboring Cell List neighbor base station can not promptly need certain neighbor base station of deletion from Neighboring Cell List as neighbor base station.

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

If WFAP detects Neighboring Cell List when changing, Home eNodeB can directly upgrade its Neighboring Cell List or wait for that SON sends the Neighboring Cell List that upgrades himself behind the Indication message again.

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

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

After step 203, SON server are received the information of Home eNodeB A transmission, send the affirmation information of receiving this information to this Home eNodeB A;

This step 203 is an optional step.

Step 204, the SON server carries out verification to the lastest imformation of receiving Neighboring Cell List, and detect and 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;

The SON server carries out verification to the lastest imformation of receiving Neighboring Cell List, is meant 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 carrying out verification.

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

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

The Home eNodeB that need carry out adjacent-area list renewing comprises one of following base station at least: to the Home eNodeB of described self-organizing network server transmission indication information, the newly-increased neighbor base station that comprises in the indication information that described self-organizing network server sends; The neighbor base station of the deletion that in the indication information that described self-organizing network server sends, comprises; Put the detected Home eNodeB that needs to upgrade Neighboring Cell List of check table according to the adjacent area interworking.

The SON server detects when needing to carry out the Home eNodeB of information updating in the Neighboring Cell List, considers that also interworking puts principle.For example, base station A detects newly-increased adjacent area B, after the SON server is received this information so, be not only base station A and need increase adjacent area B newly, and base station B also needs newly-increased adjacent area A.Base station A detects needs deletion adjacent area B, after the SON server is received this information so, be not only base station A and need delete adjacent area B, and base station B also needs to delete adjacent area A.

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

The Home eNodeB that needs to carry out information updating among Fig. 2 is base station A and base station B, only makes the usefulness of example, and in actual applications, the Home eNodeB that need carry out information updating can have a plurality of.In the drawings, the message that sends to Home eNodeB A (base station A sends the base station of adjacent-area list renewing request message to the SON server) is the adjacent-area list renewing response message, the message that sends to base station B (base station B is when needing to upgrade the Neighboring Cell List of base station A, the also affected base station of its Neighboring Cell List) is the adjacent-area list renewing request message.

Be used for indicating the information of adjacent-area list renewing to comprise one of following information at least: to increase neighbor base station and information thereof at Neighboring Cell List, 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 the following update mode: increase neighbor base station and information thereof in Neighboring Cell List, deletion neighbor base station and information thereof in Neighboring Cell List are upgraded the base station information of neighbor base station in Neighboring Cell List.

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

The result of adjacent-area list renewing is successfully or fails.

Step 207a/207b is an optional step.

In the said method, the SON server is before the base station that transmission information need be upgraded to Neighboring Cell List or receive that the base station upgrades after result's the information, neighboring BS relationship in SON server self the renewal network between the base station (comprises that promptly the base station has increased neighbor base station newly, or the base station deleted neighbor base station, or the neighbor base station information of base station changes); Making the SON server preserve neighboring BS relationship is consistent with the information in the Neighboring Cell List of base station.

It is one of following constantly that himself Neighboring Cell List is upgraded in the base station: the base station is detected when needing to upgrade its Neighboring Cell List, and its Neighboring Cell List is directly upgraded in the base station; Or the 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.

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

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

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

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

Embodiment three:

Describe the SON server among the embodiment three and initiate the flow process that base station wireless parameter upgrades.The SON server detects wireless parameter need upgrade after, indication need to be upgraded the base station of wireless parameter and is upgraded its wireless parameter.Needing the base station of renewal wireless parameter can be one of following type: macro base station, little 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 upgrade.Below with reference to Fig. 3, specify the SON server and initiate Home eNodeB wireless parameter method for updating, specifically may further comprise the steps:

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

The relevant performance parameter of wireless parameter is gathered in the base station, and reports to the SON server.The 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; (for example do not compare with certain threshold value) when these performances do not meet the demands, then which wireless parameter the SON server can be analyzed and need upgrade and recommend new value to improve this performance.In addition when wireless parameter done reshuffle after, 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 incidents acquire a certain degree (number or percentage), then the 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 handoff request, and serving BS is initiated to the thresholding of target BS switching etc.

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

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

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

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

After step 303, Home eNodeB are received the described first information of step 302, upgrade wireless parameter;

Step 304, Home eNodeB sends second information (promptly the configuration response message among the figure carries in the message and upgrades object information) that the wireless parameter of indicating this Home eNodeB upgrades the result to the SON server, promptly notifies the result of its renewal of SON server.The result that Home eNodeB carries out the wireless parameter renewal is successfully or fails.

In the said method, the SON server received perhaps (the expression Home eNodeB upgrades the wireless parameter success) after second information that Home eNodeB sends that the SON server update self was preserved the wireless parameter of this Home eNodeB before Home eNodeB sends the first information.

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

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

Be updated to example with switching-related parameters:

Specific embodiment one:

Reach threshold value (for example surpass some, perhaps reach certain percentage) when SON learns certain base station too early incident that switches, then may improve thresholding that MS initiates handoff request, improve the thresholding etc. that serving BS switches to target BS.

Specific embodiment two:

Reach threshold value (for example surpass some, perhaps reach certain percentage) when SON learns certain base station late incident that switched, then may reduce thresholding that MS initiates handoff request, reduce the thresholding etc. that serving BS switches to target BS.

Specific embodiment three:

Reach frequent generation (for example surpass some, perhaps reach certain percentage) when SON learns certain regional ping-pong, then may adjust the relevant handoff threshold value of relevant base station, this zone.

Embodiment four:

Describe Home eNodeB among the embodiment four 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;

The relevant performance parameter of wireless parameter is gathered in the base station, 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.; The base station is except reporting the SON server to these performance relevant parameters, and whether self also can analyze with these performance relevant parameters needs to upgrade; For example when above-mentioned these Key Performance Indicators (KPI, Key Performance Indication) when reaching certain thresholding, then which wireless parameter the base station can be analyzed and need 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 incidents acquire a certain degree (number or percentage), then the base station can be triggered and be upgraded the 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 handoff request, and serving BS is initiated to the threshold value of target BS switching etc.

If WFAP is through performance evaluation, when needing to upgrade 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.

Step 402, Home eNodeB A sends the first information have the wireless parameter lastest imformation (i.e. config update request message among the figure to the SON server, carry the lastest imformation of wireless parameter in the message), this Home eNodeB of notice SON server need upgrade its wireless parameter;

If the wireless parameter that performance of handoffs causes upgrades, then Home eNodeB A can comprise that to the first information that upgrades the relevant wireless parameter of performance of handoffs that is used to indicate that the SON server sends following information one of at least: new threshold value, the triggering terminal of triggering terminal scanning reports the new threshold value of scanning result, triggering terminal to initiate the new threshold value of handoff request, and serving BS is initiated to the new threshold value that target BS switches etc.

After step 403, SON server are received the first information of Home eNodeB transmission, send second information (i.e. config update request acknowledge message among the figure) of receiving this validation of information to this Home eNodeB;

This step 403 is an optional step.

Step 404, the SON server is to receiving wireless parameter lastest imformation in the described first information and check and analyzing.Check and analyze and mainly comprise one of following content:

A, the validity of the lastest imformation of receiving wireless parameter is checked, whether for example seen in reasonable range etc.,, then need to readjust if not in the reasonable scope;

B, from overall performance, wireless parameter lastest imformation to this Home eNodeB request is assessed, the renewal to certain performance-relevant wireless parameter of this Home eNodeB request, if cause other degradation of this Home eNodeB, so this variation must be controlled in the reasonable scope, promptly the SON server must adjust to the lastest imformation of the wireless parameter of Home eNodeB request in this case, reaches a compromise result as far as possible; Thisly compromise comprise that also the wireless parameter that the SON server does not ask to upgrade to this Home eNodeB adjusts.

C, from performance of the entire network, wireless parameter lastest imformation to this Home eNodeB request is assessed, the renewal of the wireless parameter of this Home eNodeB request, if cause the degradation of other adjacent base station of this Home eNodeB, so this variation must be controlled in the reasonable scope, promptly the SON server must adjust to the lastest imformation of the wireless parameter of Home eNodeB request in this case, reaches a compromise result as far as possible; This compromise SON server that also comprises is adjusted the wireless parameter of this adjacent other base station of Home eNodeB, and the wireless parameter that triggers adjacent base station upgrades the same SON server triggers of this process Home eNodeB wireless parameter renewal process.

Step 405a/405b, the SON server sends the 3rd information (i.e. config update response message among the figure, or config update request message) that has the wireless parameter lastest imformation to the base station (can be macro base station and/or Home eNodeB) that needs carry out the wireless parameter renewal.

Send to the lastest imformation that wireless parameter lastest imformation and base station A in the config update response message of base station A send to the wireless parameter in the config update request message in the configuration change request message of SON server at the SON server and compare, can be identical or the former on the latter's basis, adjust.

The 3rd information that sends to base station A is carried the renewal of wireless parameter and one of can be in the following way represented:

(1) the 3rd information has the full content of the lastest imformation of its wireless parameter;

(2) the 3rd information only have with first information wireless parameter lastest imformation in different piece, comprising:

A. new field and value thereof;

B. same field that value is different and value thereof.

The Home eNodeB that need carry out the wireless parameter renewal comprises one of following base station at least: the Home eNodeB that sends the first information to described self-organizing network server; Other Home eNodeB according to performance of the entire network assessment needs renewal wireless parameter upgrades other Home eNodeB that causes wireless parameter to upgrade because of described Home eNodeB wireless parameter.

Needing to carry out the Home eNodeB that wireless parameter upgrades (being updated to example with handoff parameter) among Fig. 4 is base station A and base station B, only makes the usefulness of example, and in actual applications, the Home eNodeB that need carry out information updating can have a plurality of.In the drawings, the message that sends to Home eNodeB A (base station A sends the base station of config update request message to the SON server) is that response message is upgraded in config update, the message that sends to base station B (base station B is when needing to upgrade the wireless parameter of base station A, the also affected base station of its wireless parameter) is the config update request message.

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

Step 407a/407b, Home eNodeB A and Home eNodeB B send the 4th information (promptly the A base station sends the config update affirmation among the figure, or the B base station sends the config update response) that the indication wireless parameter upgrades the result to the SON server; The result that wireless parameter upgrades is successfully or fails.

Step 407a/407b is an optional step.

In the said method, the SON server sends before the 3rd information of upgrading wireless parameter to the base station, or receives that the base station sends after wireless parameter renewal result's (success) the 4th information, and SON server self upgrades the wireless parameter of base station in the network.

It is one of following constantly that himself wireless parameter is upgraded in the base station: the base station is detected when needing to upgrade its wireless parameter, and its wireless parameter is directly upgraded in the base station; Or the base station is received after the information of its wireless parameter is upgraded in the indication of SON server and is upgraded its wireless parameter again.

Need to upgrade if the macro base station wireless parameter is surveyed in the SON service in the above-mentioned steps 404, then can also trigger macro base station wireless parameter renewal process.

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

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

Above-mentioned steps also is applicable to the process of the renewal wireless parameter that other type of base station (macro base station, little base station, femto base station etc.) triggers.

Embodiment five

Embodiment five is meant that the base station reports the performance schematic flow sheet of (mainly comprising wireless performance) to the SON server.

Step 501, Home eNodeB is collected performance parameter; These performances are including, but not limited to following performance: performance of handoffs, call features, capacity and covering correlated performance, interference correlation can etc.; Wherein said performance of handoffs including, but not limited to: switch too early, switched lately, switch total ping-pong.

Step 502, Home eNodeB report performance parameter to give SON server.Home eNodeB reports performance to have dual mode at least:

Directly report: what is called directly reports, to switch to example.Handover event of every generation (or success, perhaps failure), the base station can report the SON server to the relevant information of handover event; Analyzing from these handover events by SON, which kind of unusual handover event occurring, need upgrade in switching which relevant handoff parameter.

Report after the analysis: report after so-called the analysis, to switch to example.Not all handover event all reports, and only occurs to switch unusually, even switches the unusual thresholding that surpasses, and the dependent event that the base station just can unusual handover event reports the SON server.SON directly analyzes from these unusual handover events, need upgrade in switching which relevant handoff parameter.Perhaps, needing to upgrade which handoff parameter is determined by base station oneself.

Step 503, receive that Home eNodeB reports performance parameter after, the SON server sends acknowledge message to Home eNodeB; This step is optional.

Step 504, SON server initiate to upgrade Home eNodeB wireless parameter flow process.Its idiographic flow is with embodiment three.

The wireless performance parameter that the analysis of SON server is received, in case find that performance can not meet the demands, or (for example, cutting off rate reaches default thresholding to reach certain default threshold value, handoff failure reaches certain thresholding), then trigger and upgrade Home eNodeB wireless parameter flow process.

Above-mentioned steps is applicable to that also other type of base station (macro base station, little base station, femto base station etc.) reports the performance parameter flow process.

The SON server is a network element of realizing the SON function in the foregoing description one, two, three, four, five, and other network element that the SON server also can be implemented the SON function replaces.

The information of transmitting between network element in the foregoing description one, two, three, four, five can directly transmit by message, perhaps adopt TR069, Simple Network Management Protocol (Simple Network Management Protocol, be called for short SNMP), the agreement carryings such as (Data-Over-Cable Service Interface Specifications are called for short DOCSIS) of wire cable data, services interface specification.SON server in the said process also can be replaced by network management system (Network Management System is called for short NMS).

The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
