Description
Technical field
The present invention relates to LTE (LongTermEvolution, Long Term Evolution) technical field, particularly relate to a kind of method and the device that upgrade Neighboring Relation Table.
Background technology
ANR (AutomaticNeighbourRelation, Automatic Neighboring Relation) be SON (SelfOrganizingNetwork, self-organizing network) one of the key technology of function, self-configuring and the self-optimizing of neighboring BS relationship can be realized, alleviate the working strength of network planning network optimization personnel, reduce networking input and operation cost.
The main purpose of ANR function: automatically safeguard the integrality of Neighboring Relation Table, validity, reduces call drop, improves handover success rate; Reduce the human input of network planning network optimization, cut operating costs, provide the strong of network planning instrument to supplement.
The information of adjacent cells of the cell maintenance of Neighboring Relation Table to be eNB (evolvedNodeB, evolution base station) side be its service is the set of the strong pilot tone that the UE be in a community likely searches.
The meaning of Neighboring Relation Table is maintained different from the meaning of the Neighboring Cell List of legacy network in LTE system.
GSM (GlobalSystemForMobileCommunications, global system for mobile communications) and WCDMA (WidebandCodeDivisionMultipleAccess, Wideband-CDMA) system held NCL (NeighbourCellList, Neighboring Cell List) object be RBS (RadioBaseStation, wireless base station) for connected UE provides one group of adjacent cell to go to measure.In GSM and WCDMA system, UE (UserEquipment, subscriber equipment) can not measure all possible community, so wish that NCL is more short better.But LTE is different, LTEUE can decode any measurement community ID of given frequency.Therefore, LTEUE instructs measurement unlike the GSM NCL that needs the same as WCDMA system.In LTE, do not need to broadcast NCL, but need each eNB to safeguard neighboring BS relationship, such as, eNB needs to know that adjacent eNB s is the need of maintenance X2 interface etc.
PCI (the PhysicalCellIdentity of the neighbours eNB that eNB reports according to UE, physical cell identifier) judge whether at oneself Neighboring Relation Table (NeighbourRelationTable, NRT) in the middle of, if not in Neighboring Relation Table (NRT), the idle UE then finding some to be in connected state issues ReportCGI (reporting cell overall identification) Survey control message, these UE are allowed to measure the ECGI (E-UTRANCellGlobalIdentifier of given PCI adjacent area, EUTRAN Cell Global Identifier) information, if certain UE successfully reports ECGI information, then this neighboring BS relationship is added Neighboring Relation Table by ANR function.For UTRAN/GSM/CDMA community, then UE reports is CGI (CellGlobalIdentifier).
In order to obtain neighboring BS relationship, need to depend on the measurement message just having certain UE to report this adjacent area, because UE reports number of times limited, such as only prepare to switch at needs and just report, therefore some community is not easy to be found by UE in fact, and such neighboring BS relationship is just easily omitted.

Embodiment
For solving the technical problem existed in prior art, thinking of the present invention is as follows: the signaling being contained neighboring BS relationship by analysis package, such as X2SetupRequest/Response (X2 sets up request/response) or eNBconfigurationUpdate can carry the information of the other side adjacent area, obtain the neighboring BS relationship likely existed, and then sending measuring control information obtains neighboring BS relationship.This is because neighboring BS relationship is unidirectional, if namely community A exists community, adjacent area B, but just necessarily there is A the adjacent area of not talkative community B.The characteristic of combining wireless system can be known, there is B the adjacent area of A, and generally also this adjacent area that there is B is A.Therefore, if obtained the neighboring BS relationship of the other side adjacent area by information analysis, then ReportCGI Survey control message can be issued to determine the adjacent area of whether Ye Shizhe community, the other side community to this community UE.
Based on above analysis, the invention provides a kind of method upgrading Neighboring Relation Table, adopt following technical scheme:
First base station (eNB1) obtains the neighboring BS information of the community that adjacent second base station (eNB2) is administered by signaling, if comprise the neighboring BS relationship of-> eNB1 community, eNB2 community (namely the adjacent area of eNB2 community is eNB1 community) in described neighboring BS information, and in the Neighboring Relation Table of described eNB1 community, there is not the neighboring BS relationship that adjacent area is described eNB2 community (-> eNB2 community, eNB1 community), then using the potential adjacent area of described eNB2 community as described eNB1 community, connected state UE idle in described eNB1 community issues ReportCGI Survey control message, to determine that whether described eNB2 community is the adjacent area of described eNB1 community, if, then described eNB2 community is added the Neighboring Relation Table of described eNB1 community.
Wherein, described eNB1 obtains neighboring BS information by following signaling:
Based on the X2SetupRequest/Response of X2 interface;
Or based on the eNBConfigurationUpdate (base station configuration updating) of X2/S1 interface.
Wherein, in X2SetupRequest/Response or eNBConfigurationUpdate message, comprise NeighbourInformation (neighboring BS information) IE (InformationElement, information unit), this IE contains the neighboring BS relationship of transmit leg community.
Wherein, what NeighbourInformationIE comprised is direct E-UTRAN neighboring BS information.
Difference on above-mentioned two kinds of signaling content is: what comprise in X2SetupRequest/Response is the information of all Serving cells of adjacent eNB and adjacent area thereof; What comprise in eNBConfigurationUpdate is interpolation, amendment or the Serving cell of deletion and the information of adjacent area thereof, therefore, the present invention also comprises interpolation Serving cell and neighboring BS information thereof, and amendment Serving cell and neighboring BS information assess, to obtain potential neighboring BS relationship, and then sending measuring control message, whether checking exists neighboring BS relationship.
Further, described eNB1 determines that whether described eNB2 community is the adjacent area of described eNB1 community in the following manner:
If receive the ReportCGI result that described UE reports within the then time of setting, then confirm that described eNB2 community is the adjacent area of described eNB1 community.
Further, described eNB1 using described eNB2 community as described eNB1 community potential adjacent area while, in described Neighboring Relation Table, add the potential neighboring BS relationship item of-> eNB2 community, eNB1 community; If setting to do not receive yet constantly described UE report ReportCGI result, then delete the potential neighboring BS relationship item of-> eNB2 community, described eNB1 community.
Below in conjunction with the accompanying drawings and the specific embodiments technical solution of the present invention is described in further detail.
The neighboring BS relationship of the embodiment of the present invention finds flow process as shown in Figure 1, when transmit leg is eNB1, when recipient is eNB2, after eNB2 finds potential neighboring BS relationship, confirms that the key step of neighboring BS relationship is described below:
Step 101, eNB2 receives the X2SetupRequest/Response from eNB1, or eNBConfigurationUpdate signaling information, wherein contains the Serving cell of eNB1 and respective neighboring BS information thereof;
If what receive is X2SETUPREQUEST/Response message, then wherein contain the information of all Serving cells of eNB1 and their respective adjacent areas;
If the information that eNB2 receives is eNBConfigurationUpdate, then can obtain eNB1 and add Serving cell and their respective neighboring BS information, namely obtain the Serving cell below ServedCellsToAddIE (adding service cell information unit) and adjacent area content thereof; Or the Serving cell obtained below ServedcellstoModifiedIE (amendment service cell information unit) and adjacent area content thereof.
Step 102, eNB2 analyzes the Serving cell of eNB1 and the information of respective adjacent area thereof, and in the neighboring BS relationship of record eNB1, adjacent area is the neighboring BS relationship of the community of eNB2 administration;
Step 103, according to the neighboring BS relationship of eNB2 from the neighboring BS relationship of-> eNB2 community, eNB1 community of record, find out the item of the potential neighboring BS relationship of-> eNB1 community, eNB2 community, be recorded in the Neighboring Relation Table of eNB1 community, such as, recording mode is eNB2 community is Serving cell, and eNB1 community is potential adjacent area;
Step 104, judges whether-> eNB1 community, potential eNB2 community neighboring BS relationship quantity is zero, if be zero, enters step 110, otherwise enters step 105;
Step 105, getting a potential neighboring BS relationship is currentitem;
Step 106, finds idle connected state UE in currentitem Serving cell (i.e. eNB2 community) and issues ReportCGI Survey control message, to determine that whether potential adjacent area (eNB1 community) is the adjacent area of eNB2 community;
Step 107, in this example, can according to the then time T of eNB2 community in setting
abortinside whether receive UE and report ReportCGI result, enter step 109 if do not received, otherwise enter step 108;
Step 108, if receive UE to report ReportCGI result (i.e. the ECGI/CGI of eNB1 community), the CGI of eNB1 community is then obtained according to ReportCGI result, judge whether that meeting adjacent area adds condition, namely this UE received reports (PCI in result, CGI) whether information does not exist in the Neighboring Relation Table of eNB1 community, if there is not (the PCI in UE report result in the Neighboring Relation Table of eNB1 community, CGI) information pair, then by neighboring BS relationship, it adds in Neighboring Relation Table, completes the renewal of Neighboring Relation Table;
In this step, due to before the report result receiving UE during this period of time in Neighboring Relation Table that likely eNB2 community has added eNB2 community as adjacent area suffered, therefore, preferably, add the operation judging whether to meet adjacent area and add condition.
Step 109, T
abortthen, if do not receive UE yet to report ReportCGI result, then delete current potential neighboring BS relationship, return step 104;
Step 110, this flow process terminates.
Adopt technique scheme, greatly can improve adjacent area and find speed, particularly at the networking initial stage, owing to reporting PCI report result less, be not easy to find potential adjacent area.Adjacent area can be found on one's own initiative by our rule, and then arrange UE to report these neighboring BS relationship.

Step 205: getting a potential neighboring BS relationship is currentitem, be neighboring BS relationship B4-> A4 here, wherein B4 is Serving cell, and A4 is adjacent area.
Step 206: find idle connected state UE and issue ReportCGI Survey control message in the B4 of currentitem Serving cell, PCI value is 4, to determine A4 whether for the adjacent area of B4, if neighboring BS relationship then can obtain the CGI of potential adjacent area.
Step 207:eNB2 currentitem Serving cell be here B4 community within the Tabort time, whether receive UE after such as 1 second and report ReportCGI result, enter step 209 if do not received, otherwise enter 208.Suppose to receive certain UE in B4 community and report result, obtain the ECGI=10008 of the A4 community of PCI=4.
Step 208: add neighboring BS relationship.
The Neighboring Relation Table of table 3B4 community
Step 209: delete current potential neighboring BS relationship, return step 204, because potential neighboring BS relationship only has one, so flow process enters step 210.
Step 210: flow process terminates.
Application example two
This example, for base station A and base station B, supposes that base station B have received eNBConfigurationUpdate message, carries Serving cell A4 and neighboring BS information thereof that base station A newly adds.
Step 301: base station B receives the eNBConfigurationUpdate signaling information from base station A, wherein contains the Serving cell of base station A and respective neighboring BS information thereof.Such as obtain Serving cell A4 that base station A newly adds and neighboring BS information thereof, information list is:
The Serving cell that table 4eNBA newly adds and neighboring BS information thereof
| Serving cell | Serving cell PCI | Adjacent area | Adjacent area PCI |
| A4 | 4 | A1 | 1 |
| A2 | 2 | ||
| A3 | 3 | ||
| A5 | 5 | ||
| A6 | 6 | ||
| A7 | 7 | ||
| B4 | 14 |
Step 302:eNB2 analyzes the Serving cell of eNB1 and the information of respective adjacent area thereof, and in the neighboring BS relationship of record eNB1, adjacent area is the neighboring BS relationship of the community of eNB2 administration.Here have found the neighboring BS relationship of A4-> B4.
Step 303: the neighboring BS relationship according to eNB2 finds out-> eNB1 community, potential eNB2 community neighboring BS relationship item from the neighboring BS relationship of-> eNB2 community, eNB1 community of record, recording mode is eNB2 community is Serving cell, and eNB1 community is potential adjacent area.Here there is neighboring BS relationship in B4-> A4, and therefore potential neighboring BS relationship is zero.
