Description
Technical field
The present invention relates to communication field, relate in particular to the update method of a kind of Home eNodeB adjacent area tabulation.
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-Organized Network 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.

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 Access Network operator (NAP) with this Home eNodeB, also can belong to different N AP, and different neighbor base stations also can belong to different N AP.The information of neighbor base station comprises one of following information at least: base station identification information, frequency information, Access Network operator sign, whether in running order, whether allow to switch.Wherein, base station identification information comprises one of following information at least: base station MAC layer sign (BS ID), prefix index, cell ID (CellID).
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.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 base station information in the Neighboring Cell List of base station need upgrade after, 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 needs in the Neighboring Cell List to upgrade 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 needs to upgrade.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:
The base station information that step 101, SON server detect in the tabulation of Home eNodeB adjacent area needs 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 the base station information that can detect in the tabulation of Home eNodeB adjacent area needs to upgrade.The SON server can be known the state of base station in the whole network, also can know the base station that is in non operating state, and also can know needs base station newly-increased or deletion.
When detecting following situation, the SON server judges that the base station information in the tabulation of Home eNodeB adjacent area needs to upgrade:
(1) certain base station changes to non operating state from operating state, and 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.;
(2) newly-increased certain base station; This newly-increased base station is meant the base station that is in normal operating conditions of new interpolation;
(3) delete certain base station.
The SON server detects base station information in the Home eNodeB adjacent area tabulation need upgrade after, upgrade the neighboring BS relationship of base station in the network of self preserving.
Step 102, the SON server sends the Indication message that is used to indicate the renewal Neighboring Cell List to the Home eNodeB that needs upgrade Neighboring Cell List, notifies this Home eNodeB to upgrade Neighboring Cell List;
The SON server carries one of following information in the message 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; Need to upgrade the lastest imformation of the neighbor base station of base station information 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.
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.
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 Indication message 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; Perhaps this base station of mark is in non operating state in Neighboring Cell List, and the information of perhaps upgrading this base station from Neighboring Cell List is can not be as the target BS that switches.
Step 103, Home eNodeB are upgraded its Neighboring Cell List after receiving the described message 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 message.The result that Home eNodeB carries out adjacent-area list renewing is successfully or fails.
In the said method, the SON server sends before the renewal result's who indicates this Home eNodeB the message to Home eNodeB, also need to upgrade earlier the neighboring BS relationship of base station in its network topology structure information, the lastest imformation of neighboring BS relationship is consistent with adjacent-area list renewing information, comprise 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.
Above-mentioned steps also is applicable to the process of the renewal macro base station 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 message 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 neighboring BS relationship between the base station in the network of self preserving on the one hand, promptly this base station state of mark is a non operating state, promptly can not be used for switching.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 switching 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.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 is found, be that the following message of terminal to report is found one of at least newly-increased neighbor base station: the scanning result reporting message, or handoff request message, or switch indicating information, or context request message etc.; Promptly occurred the neighbor base station that do not comprise in the Neighboring Cell List in these message, 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.
The base station information that Home eNodeB detects in the Neighboring Cell List one of in the following manner changes: by the message of terminal to report; Or by self scanning to neighbor base station.Described terminal to report message comprises one of following message at least: scanning result report message, handoff request message, switch indicating information, context request message.
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 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 to the SON server and is used to indicate the message of upgrading Neighboring Cell List, its Neighboring Cell List of update notifications;
Home eNodeB A indicates the message of upgrading Neighboring Cell List can comprise a kind of of following message to SON server being used for of sending: newly-increased neighbor base station and information thereof; The neighbor base station and the information thereof of deletion; Neighbor base station that base station information need upgrade and lastest imformation thereof.
After step 203, SON server are received the message of Home eNodeB A transmission, send the affirmation message of receiving this message to this Home eNodeB A;
This step 203 is an optional step.
Step 204, the SON server detects need carry out the base station (comprising macro base station and Home eNodeB) of adjacent-area list renewing, and upgrades the neighboring BS relationship of base station (comprising macro base station and Home eNodeB) in the network of self preserving;
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 message, the newly-increased neighbor base station of indicating in the Indication message that described self-organizing network server sends; The neighbor base station of the deletion of in the Indication message that described self-organizing network server sends, indicating; 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 205, the SON server sends the response message that the described message of step 204 is received in indication to Home eNodeB A;
Step 206, the SON server sends the message that is used to indicate adjacent-area list renewing 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.
Be used for indicating the message of adjacent-area list renewing to comprise a kind of in the following information: in Neighboring Cell List, increase neighbor base station and information thereof, or in Neighboring Cell List deletion neighbor base station and information thereof, or in Neighboring Cell List, upgrade the base station information of certain neighbor base station.
Step 207, 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.
The result of adjacent-area list renewing is successfully or fails.
Step 207 and step 208 are optional steps.
In the said method, the SON server is before the base station that transmission message need be upgraded to Neighboring Cell List, and SON server self upgrades the neighboring BS relationship between the base station in the network; The lastest imformation of neighboring BS relationship is consistent with adjacent-area list renewing information, 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.
