Description
Technical field
The present invention relates to a kind of Neighboring Cell List maintenance technology of network side network element, relate in particular to a kind of Neighboring Cell List automatic maintenance method and system.
Background technology
In communication system; In order to reduce the cost of networking and operation, traditional drive test is to test with artificial zone to needs monitoring and optimization, and in the evolution system based on next generation network; Reduction is necessary to the dependence of traditional drive test and through more intelligent network optimization tool; Therefore, realizing collection and the demand of minimize human drive test of the metrical information at drive test terminal (also being subscriber equipment) automatically, is very useful.On the other hand, utilize the test result of subscriber equipment (UE, User Equipment) automatically to be optimized, and the network operation is had comprehensive understanding network.Therefore; At Long Term Evolution (LTE; Long Term Evolution) in the system minimum road test (MDT has been proposed; Minimise Drive Test) technical research should technology also can apply in the UMTS (UMTS, Universal Mobile Telecommunications System) simultaneously.Implementation measures control based on base station (eNB) and UE reports mechanism with metrical information, and Fig. 1 is the configuration diagram of MDT, and is as shown in Figure 1; NMS and wireless access network (RAN, Radio Access Network) are positioned at the network side of mobile network, comprise eNB among the RAN; By RAN UE is measured control, send to UE, after UE receives and measures the control signaling as will measure the control signaling through idle message etc.; Carry out drive test; And the relevant information that drive test obtains reported to RAN, and report to NMS by RAN, NMS is carried out operations such as the network optimization according to the drive test relevant information.Concrete, the drive test of above-mentioned UE comprise mainly that daily record under reporting the immediately UE connected state under, free time (IDLE) attitude reports and connected state under daily record report three types.
In addition, mobile subscriber's service continuity is an essential characteristic of cell mobile communication systems, and the switching of subscriber equipment Serving cell is the main means that guarantee service continuity.Switch for the ease of subscriber equipment; GSM need be given each cell configuration syntople; So that network side notifies neighboring BS information to subscriber equipment, subscriber equipment is measured back reporting measurement result to the adjacent area, switches to a certain adjacent area by network side indication subscriber equipment again.Have around certain sub-district which adjacent area not only with the sub-district distance dependent, and closely related with the residing wireless environment in sub-district.Because wireless environment is intricate, especially the intensive urban area circumstance of skyscraper is difficult to certain sub-district of definite judgement at the network planning initial stage and should disposes which adjacent area.Also have some to change the neighbouring relations of the sub-district that do not upgrade in time as having increased a sub-district or cell attribute in the system newly; The perhaps variation of environment, network planning personnel's omissions etc., it is untimely all can to cause neighboring BS information to upgrade.And utilize the MDT technology can make full use of the metrical information of drive test UE, wireless environment situation is on every side collected reported.Fig. 2 realizes automatic adjacent section information reporting flow chart for utilizing MDT to measure, and as shown in Figure 2, the automatic adjacent section information reporting specifically may further comprise the steps in the prior art:
Step 201: the cell-of-origin selects suitable UE to carry out the ANR measuring task; For all UE that are arranged in the sub-district, be not all to be suitable for ANR to measure, need select for use more suitable UE to carry out the measurement of neighboring BS information;
Step 202: UE is handed down to the ANR configuration information in the cell-of-origin; Here, the ANR configuration information can be notified to all UE through broadcast mode, or only notice is given the UE that needs to carry out drive test.The ANR configuration information mainly is that requirement UE carries out that neighboring BS information is measured and reports on suitable opportunity.
Step 203:UE carries out ANR measurement and record measurement result, can in cell re-selection procedure, carry out;
Step 204:UE reports the indication of ANR LOG measurement and report to Target cell;
Step 205: Target cell sends surveying record to UE and obtains request;
Step 206:UE carries out reporting of ANR LOG measurement result to Target cell;
Step 207: Target cell is safeguarded neighboring BS relationship according to the drive test result that UE reports.
Because record can be carried out to the adjacent area in different positions in the moving process in the drive test terminal in network; The terminal can be with the service cell information that records and corresponding adjacent zone information reporting arbitrary eNB or radio network controller (RNC in the network; Radio Network Controller); And network side need be with the transmitting neighbor information of drive test terminal to report eNB/RNC or the corresponding eNB/RNC in adjacent area to the Serving cell place, could handle and safeguards the neighboring BS information of terminal to report.Reporting of present drive test neighboring BS information, the eNB/RNC that does not relate to information reporting selects, and obviously, if the eNB/RNC that the drive test result is reported is improper, can not realize effective renewal of relevant adjacent area, sub-district.
