In practical application, communication unit 30 and confirmation unit 31 can be arranged in RNC, and performance element 32 is arranged in background devices; Or, communication unit 30 is arranged in RNC, and confirmation unit 31 and performance element 32 is arranged in background devices.
Based on technique scheme, in the embodiment of the present invention, coming from the RRC connection establishment request message of the first community and coming from the RRC connection establishment request message of the second community of UE transmission is determined if receive respectively, when then there is no the cell ID of the second community in the Neighboring Cell List of confirmation first community, Neighborhood Optimization process is carried out as the miss-configured neighboring cells of the first community in second community, consult Fig. 4 to show, in the embodiment of the present invention, the detailed process that RNC realizes Neighborhood Optimization based on the cell reselection of UE is as follows:
Step 400:UE resides in CELL1, and makes a call on CELL1.
Step 401:UE sends the request of RRC connection establishment to CELL1, i.e. RRC CONNECT REQUEST, at least carries the cell ID of CELL1 in this RRC connection request message, be called mark 1.
In the present embodiment, backstage can obtain Neighboring Cell List to the CELL1 that should identify 1 preservation according to mark 1, records the cell ID of all adjacent areas of CELL1 in this Neighboring Cell List.
The RNC Forward-reques message of reception is forwarded to RNC by step 402:CELL1.
This RRC connection request message is recorded in daily record, and is UE distributing radio resource at CELL1 after receiving the RRC connection establishment request of UE transmission by step 403:RNC.
Step 404:UE, in the process waiting for network side response, there occurs cell reselection and reselects to CELL2.
Step 405:UE initiates RRC connection establishment request message again to CELL2, i.e. RRCCONNECT REQUEST, at least carries the cell ID of CELL2 in this RRC connection request message, is called mark 2.
After step 406:CELL2 receives the RRC connection establishment request of UE, forward this RRC connection establishment request message to RNC.
This RRC connection establishment request message is recorded in daily record, and is that UE is in CELL2 distributing radio resource after receiving the RRC connection establishment request message of UE transmission by step 407:RNC.
When distributing radio resource, need allocation result to notify UE and CELL2, also will discharge the Radio Resource of UE at CELL1 simultaneously.
Step 408: background devices obtains the daily record of RNC.
In the present embodiment, namely background devices can be Network Management Equipment, also can be network optimization equipment, and the daily record of RNC can initiatively be sent to background devices by RNC, also initiatively can be obtained to RNC by background devices.
Step 409: the daily record of background devices to the RNC obtained is analyzed, determine the cell ID not configuring CELL2 in the Neighboring Cell List of CELL1, when namely identifying 2, illustrate that CELL2 is that CELL1 exists miss-configured neighboring cells, now need to perform Neighborhood Optimization operation for CELL1, as, mark 2 is increased in the Neighboring Cell List of CELL1, other relevant informations of CELL2 can also be increased further, e.g., the pilot power, frequency information, scrambling code information, cell reselection parameters etc. of CELL2.
In the present embodiment, after execution step 407, RNC can perform adjacent area leakage further and join judgement according to the RRC connection request message received, judged result is recorded in daily record and mails to background devices, be specially: after RNC receives the RRC connection establishment request sent by CELL2 of UE, perform following operation:
First RNC will judge whether RNC this locality records the relevant information of UE, if, RRC connection establishment request message was once sent before then UE being described, and if UE is being in RRC connection establishment state, then illustrate that network is just at the RRC connection establishment request message that UE once sent;
Then, RNC judges whether the RRC connection establishment request message of double reception comes from same community, in the present embodiment, the RRC connection establishment request that RNC records UE first time transmission comes from CELL1, and the RRC connection establishment request that second time sends comes from CELL2;
Finally, RNC judges whether the Neighboring Cell List of CELL1 is configured with the cell ID of CELL2, namely identifies 2, if so, then illustrates to there are not miss-configured neighboring cells, then RNC records the RRC connection establishment request message coming from CELL2 that UE sends, and terminates current process; Otherwise, RNC determines that CELL2 is the miss-configured neighboring cells of CELL1, and in daily record, record the RRC connection establishment request message coming from CELL2 of UE transmission, and add in this RRC connection establishment request message adjacent area leak join information, this adjacent area is leaked and is joined in information the cell ID comprising CELL1, namely 1 is identified, for characterizing the miss-configured neighboring cells that CELL2 is CELL1.
So, in step 408 and step 409, background devices obtains daily record from RNC, and according to the RRC connection establishment request message that log recording determines to come from CELL2 exist adjacent area leak join information time, join the mark 1 of preserving in information according to the leakage of this adjacent area and obtain corresponding Neighboring Cell List, and mark 2 is added in this Neighboring Cell List, automatically to complete Neighborhood Optimization operation; Or, present information over the display, administrative staff are reminded to need to increase the cell ID of CELL2 in the Neighboring Cell List of CELL1, make corresponding Neighborhood Optimization by administrative staff to operate, wherein, adjacent area can be leaked and be joined the content such as information and Neighborhood Optimization suggestion, by mail sending in the mailbox of administrative staff by background devices.Or, information is joined in adjacent area leakage and is prompted to administrative staff by the form of alarm.
In practical application, preferably, it is behind the miss-configured neighboring cells of CELL1 that background devices determines that information representation CELL2 is joined in the adjacent area leakage of the RRC connection establishment request message that a certain UE sends, Neighborhood Optimization operation can not be performed immediately, but continue the RRC connection establishment request message of process by other UE transmission under same RNC, when RNC determine to have preserved for characterize CELL2 be the adjacent area of the miss-configured neighboring cells of CELL1 leak the number of joining information exceed setting threshold value time, then perform the operation of corresponding Neighborhood Optimization.
Be different from above-mentioned processing mode, in step 407, RNC is after acquisition comes from the RRC connection establishment request message of CELL2, this RRC connection establishment request message is recorded in daily record, do not judge whether to there are miss-configured neighboring cells, and in step 408 and step 409, after obtaining daily record by background devices, judge whether to there are miss-configured neighboring cells according to daily record again, be specially:
First, background devices obtains the daily record of RNC, and in practical application, background devices can obtain the daily record of multiple RNC, and extracts the RRC connection establishment request message sent by same UE;
Then, background devices judges, the RRC connection establishment request message of adjacent twice reception of same UE comes from different districts respectively, and the RRC connection establishment request that in the present embodiment, the RRC connection establishment that record UE first time sends please come from CELL1, record UE second time sends comes from CELL2;
Preferably, background devices also needs to judge further that the double time interval receiving the request of RRC connection establishment is less than predetermined value (e.g., 10s, this parameter can flexible configuration according to demand), just performs subsequent operation.
Finally, background devices judges whether the Neighboring Cell List of CELL1 is configured with the cell ID of CELL2, namely identifies 2, and if so, then illustrate to there are not miss-configured neighboring cells, background devices will terminate current process; Otherwise, background devices determines that CELL2 is the miss-configured neighboring cells of CELL1, and information is joined in the RRC connection establishment request message record adjacent area leakage that correspondence comes from CELL2, and this adjacent area is leaked and joined in information the cell ID comprising CELL1, namely 1 is identified, for characterizing the miss-configured neighboring cells that CELL2 is CELL1.
Now, the adjacent area that the RRC connection establishment request message that background devices comes from CELL2 according to correspondence is preserved is leaked and is joined the Neighboring Cell List that the mark 1 comprised in information obtains CELL1, and mark 2 is added in this Neighboring Cell List, and automatically completes Neighborhood Optimization operation; Or, present information over the display, administrative staff are reminded to need to increase the cell ID of CELL2 in the Neighboring Cell List of CELL1, make corresponding Neighborhood Optimization by administrative staff to operate, wherein, adjacent area can be leaked and be joined the content such as information and Neighborhood Optimization suggestion, by mail sending in the mailbox of administrative staff by background devices.Or, information is joined in adjacent area leakage and is prompted to administrative staff by the form of alarm.
In practical application, preferably, background devices is determined that the adjacent area of the RRC connection establishment request message that a certain UE sends is leaked and is joined the miss-configured neighboring cells that information representation CELL2 is CELL1, Neighborhood Optimization operation can not be performed immediately, but continue the RRC connection establishment request message of other UE of process transmission, when backstage determine to obtain for characterize CELL2 be the adjacent area of the miss-configured neighboring cells of CELL1 leak the number of joining information exceed setting threshold value time, then perform the operation of corresponding Neighborhood Optimization.
Contrast the method for above-mentioned identification miss-configured neighboring cells, when adopting RNC to identify miss-configured neighboring cells, lower to the configuration requirement of background devices, but only can identify the miss-configured neighboring cells in RNC; And when adopting background devices identification miss-configured neighboring cells, both can identify the miss-configured neighboring cells in RNC, also can miss-configured neighboring cells between RNC.
Like this, just re-access flow process based on UE in the RRC connection establishment stage, effectively improve the recognition accuracy of miss-configured neighboring cells, avoid bring to systematic function miss-configured neighboring cells harmful effect (as, call drop, service-aware degree decline etc.), ensure that system service quality.
Further, adopt the technical scheme that the embodiment of the present invention provides, only need adjust accordingly the operational process of network side, do not need to change end side, do not need to revise protocol contents, so yet, just reduce implementation complexity to a great extent, save and realize cost.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
