Description
Technical field
The present invention relates to the communications field, in particular to a kind of method of measurement and system of neighbor cell relation.
Background technology
Along with the raising with users' demand for services that increases of cell mobile communication systems provider customer number, the scale of cellular network constantly expands, and base station number is on the increase, and the cell mobile communication systems of various standard is constantly deepened to intemperate with one another.Concomitantly, the neighboring BS relationship of cellular network small area administers and maintains becomes more and more loaded down with trivial details work, so operators expect that pure manual neighboring BS relationship management can by system automation in the past.
Unexceptionally, UTRA network operator craves for the neighboring BS relationship realization management automatically of its network cell very much.Shown in Figure 1, in UTRA network, UTRAN (Universal Terrestrial Radio Access Network, universal land radio access web) comprise RNC (Radio Network Controller, radio network controller) and NodeB (base station) two kinds of basic network elements.The neighboring BS relationship of numerous minizone under hundreds of NodeB, dynamically can change along with the needs of network planning optimization and the change of residing wireless environment.
In UTRA network, the correct neighboring BS relationship in minizone is extremely important to network performance.Such as: realize mobile subscriber, terminal UE optimal switching, ensures its service continuity, helps real-time performance load balancing, capacity is allocated, energy-conservation grade for multipurpose.Under past pure manual adjacent area layout, the neighboring BS relationship configured is in advance informed to terminal UE by system broadcast message or proprietary control message by network side, the community neighboring BS relationship that UE stores further and utilizes these to receive.But this neighboring BS relationship configured in advance from network side may be out-of-date, can not really reflect real-time neighboring BS relationship, thus UE mistake may be caused to switch, and even call drop, network performance totally declines.
In UTRA system, 3GPP introduces Automatic Neighboring Relation function (AutomaticNeighbor Relation Functionality is called for short ANRF) in version 10 (Release10) plan.Refer to Fig. 2, this scheme has used the thought of minimum drive test MDT technology (Minimize Driving Test), is the mode based on Log, and be called for short Log ANR scheme, idiographic flow step, see Fig. 2, is described as follows:
S201:UE resides in the inside, certain cell-of-origin (Source cell) under the RNC of source.Source RNC selects certain suitable terminal UE to go to perform a certain class or a few class ANRF measurement task inside cell-of-origin.The selection of this well-formedness is present in the ANRF tenability of UE oneself, residing communications status and relevant environment etc.
S202: source RNC in cell-of-origin to ANRF tasks carrying UE selected before, send certain RRC downstream message containing ANRF Survey control configuration parameter (DL Message with ANR Configurations).These ANRF configuration parameters may comprise: frequently detect the interior adjacent unknown cell of Intra-frequency UTRA, and/or UTRA is detected the adjacent unknown cell of outer Inter-frequency frequently, and/or detect across the adjacent unknown cell of LTE system (Inter-LTE), and/or detect across the adjacent unknown cell of gsm system (Inter-GSM), these 4 kinds basic ANRF measure the relevant necessary configuration information of type, the measurement such as carrying out which physical layer signal information obtains, measurement event dependent threshold, threshold value, biased, neural buffering etc., also comprise the acquisition (Layer 2 info acquistion) etc. of layer 2 information of carrying out on which physical layer alternatively.UE preserves the configuration parameter of these ANRF, proceeds other communication behaviors of its necessity.
S203:UE is after certain RRC (Radio Resource Control) Signalling exchange, UE has entered into certain suitable state be ANRF and measured, and the ANRF configuration parameter preserved before just using is that the measurement of the adjacent unknown detected cells of a certain or a few class is ready.The state being applicable to doing ANRF measurement may be Idle state Idle, paging state URA_PCH, Cell_PCH etc.
S204: the mobility possible due to UE itself or other reasons, UE mono-carry out aspect the cell measurement task in the Neighboring Cell List of the routine that non-ANRF measurement task is correlated with, for cell reselection is prepared; On the other hand, UE is according to ANRF configuration before, perform ANRF measurement task, and the measurement result meeting certain condition is recorded in (comprising physical layer information, alternatively: layer 2 information on physical layer) in the ANR table of UE inside (ANR Logging Table).This record behavior we be called for short ANR Logging or Logging, be a core concept of MDT technology.When the Neighboring Cell List Nei Mou community of UE routine meets cell re-selection conditions time, UE still according to pattern gravity treatment in the past in the Target cell in that Neighboring Cell List, can't be subject to the interference that ANRF measures task, that is ANRF measures task is subsidiary along with the gravity treatment behavior of UE conventional cell.
S205: when UE have selected the Target cell in certain Neighboring Cell List and gravity treatment enters time, if had effective logging content in UE ANR table therein, just send in certain RRC upstream message of the Target RNC at place, Target cell at it, indicate its ANRF measurement result to have and can report.
S206:UE is after certain RRC (Radio Resource Control) Signalling exchange, and UE has entered into the state that certain the suitable ANRF of being measurement result reports, and carries out and report preparation.
S207: the Target RNC at place, Target cell, by certain RRC downstream message, requires that UE carries out ANRF measurement result and reports.We claim this process to be ANR Logging Results Retrieval.
S208: according to the request of Target RNC, UE are kept at the ANRF measurement result in ANR table before reporting it by certain RRC upstream message.
S209: Target RNC, according to the ANRF measurement result obtained, safeguards its relevant Neighboring Relation Table NRT (NeighborRelation Table).
The Log ANR scheme of above-mentioned UTRA system is although be that one relatively easily realizes and to UE originally service, mobile behavior impact is less, owing to have employed the thought of MDT, so its many shortcoming of natural succession, as follows:
If 1. UE allows to do ANRF measurement and record in Idle state, so possibility effect is bad.Because Idle state UE can not carry out cell update flow process after there is cell reselection.RRC can only be adopted similarly to set up request flow process or position update flow, and this is quite large on UE non-human act impact.Measure so Idle state UE is ANRF, almost can only adopt the mode consistent with MDT, be configured ANR and record the duration (ANR logging duration), thus it is limited on the logging time, some geographic ranges or otherwise restriction may be also had, such as UE moves to outside certain position range and just stops record, just stops record etc. when moving to other system.To URA_PCH state UE, although can adopt URA Update, if URA scope is very large, URAUpdate occurrence frequency is low, and almost also similar Idle UEANR measures the behavior of logging.
If 2. UE allows to do ANRF measurement and record in PCH state, according to ANR process structure above, after UE completes cell reselection, such as cell update message Cell Update can be utilized to do the instruction of ANR Logging results immediately and report (prerequisite is that UE has successfully captured at least one adjacent unknown cell according to certain record criterion logging criteria).Be successfully completed after reporting, UE just removes old Logs immediately.This idea is fine, can reduce logging quantity, and minimizing reports time delay, is conducive to network and is optimized neighboring BS relationship in time.But, if the natural mobility of UE oneself is very slow, even as you were, so Cell Update will through for a long time could generating period cell update once, follow-up ANR logs will be postponed and indicate and report.So before this, possible UE is still ceaselessly ANR and measures and logging in same cell-of-origin, constantly attempts the detection of adjacent unknown cell, if find new better unknown cell, and the logging record had been found that before continuing to add or substitute.But the ANR having done a period of time due to UE in certain cell range measures, and the unknown neighbor cell of this existence may be captured totally, so much follow-up logging may be insignificant.

Embodiment 3
The present embodiment, the method for measurement of neighbor cell relation, comprises following basic step and feature:
Step 1: before UE performs ANRF surveying record task, comprises the parameter shown in following table 1 or cell (the first cell) in the control configuration parameter that source RNC is correlated with at the ANRF sent to UE alternatively.
Table 1
Alternatively: the parameter shown in above-mentioned first cell and/or following table 2 or cell (the second cell) can be comprised in the control configuration parameter that ANRF is correlated with:
Table 2
Step 2:UE preserves above-mentioned two parameters or cell respectively in local variable T and/or N, start ANR and measure moment of task when entering into suitable state and rise, start countdown, and/or reciprocal (note: yet can reverse countdown or forward counting, does not affect invention essence.)。The every ANR of UE measures logging 1 second in the past, T (i+1)=T (i)-1; UE often crosses over a Serving cell different with historical record before, N (i+1)=N (i)-1.
Step 3: while other possible restriction UE do the factors contribute of neighboring BS relationship surveying record, if T is overtime, namely countdown is to 0, and/or N is not that 0, UE just stops all ANR to measure logging behavior, only retains the behavior of other routines.
Step 4:UE continues other follow-up conventional behaviors, until there is the chance indicating and report ANR logs to record.
Based on the basic thought of foregoing invention, if do not consider the bits number required for these limiting parameters or cell, above-mentioned parameter or cell can refinements further, such as dissimilar ANR task, and/or perform ANR task under different RRC state, and/or under different network environments residing for UE, configure different parameter sets respectively.Conversely, if do not wish that RNC always sends so multi-parameter information, UE also can be kept in local variable with the form of acquiescence or preconfiguration parameters.The core object of all these parameters or cell is exactly: allow UE be nonsensical ANR as far as possible less and measure logging, because the unknown neighbor cell in certain block region may be caught complete by the UE in ANR limit of power.
By the method for measurement of the neighbor cell relation of the present embodiment, UE more effectively can go to carry out ANR and measure logging behavior, power saving more.
Embodiment 4
Fig. 5 is the another kind of flow chart of the method for measurement according to embodiment of the present invention neighbor cell relation, the scene of the present embodiment is that the UE that certain possesses ANR ability is in Cell_DCH data transmission state at certain cell-of-origin (Source cell), then DTD enters Cell_PCH state, is selected to go to perform ANR task by the source RNC at place, cell-of-origin.
S501, source RNC is by issuing physical channel reallocation message (Physical Channel Reconfiguration), control configuration parameter relevant for ANR is sent to UE, comprises the first cell in example 3 and assignment is as follows: Timer for ANRlogging in small area=960s;
S502, UE preserve above-mentioned parameter T=960s, start to carry out ANR and measure logging.Along with time lapse, start countdown, T=959s, 958s ...;
S503, UE do neighbor cell measurement in the Neighboring Cell List prepared for cell reselection, while do the measurement of the unknown neighbor cell that ANR is correlated with, have found a unknown neighbor cell Detected cell.In this process, the factor that other any possible restriction UE make neighboring BS relationship surveying record does not all work, until T is overtime, i.e. and T=0s, so UE just stops all ANR to measure logging behavior, but still neighbor cell measurement behavior in the Neighboring Cell List being left cell reselection and preparing;
S504, due to mobility, UE has found a suitable reselection target cell Target cell finally, so gravity treatment enters, initiates cell update flow process, and seizes the opportunity the result indicating and report ANR logs to record.
Embodiment 5
Fig. 6 is another flow chart of the method for measurement according to embodiment of the present invention neighbor cell relation, scene is that the UE that certain possesses ANR ability is in Cell_DCH talking state at certain cell-of-origin (Source cell), then end of conversation enters free time (Idle) state, is selected to go to perform ANR task by the source RNC at place, cell-of-origin.
S601, source RNC is by issuing RRC connection release message (RRC Connection Release), control configuration parameter relevant for ANR is sent to UE before UE enters Idle state, and the second cell comprised in embodiment 3 and assignment is as follows: Span of Minimum N cells for ANR logging=2;
S602, UE preserve above-mentioned parameter N=2, start to carry out ANR and measure logging.The mobility under Idle state along with time lapse and UE oneself, if UE completes once the cell reselection different with historical record, then N subtracts 1;
S603, UE do neighbor cell measurement in the Neighboring Cell List prepared for cell reselection, while do the measurement of the unknown neighbor cell that ANR is correlated with, have found a unknown neighbor cell Detected cell.In this process, the factor that other any possible restriction UE make neighboring BS relationship surveying record does not all work.In 15 minutes, UE only completes 1 cell reselection, and enters into Target Cell, but N=1 > 0, so UE just stops all ANR to measure logging behavior, and variable N is reset to initial value 2.But still neighbor cell measurement behavior in the Neighboring Cell List being left cell reselection and preparing;
S604, in Target Cell, due to needs of newly conversing, UE initiates RRC connection request flow process, and seizes the opportunity the result indicating and report ANR logs to record.
As can be seen from the above description, present invention achieves following technique effect:
UE performs neighbor cell relation according to configuration parameter in advance and measures, and meeting stopping record measurement result under predetermined condition, solving the problem of the waste electric energy caused due to the unnecessary logging of UE, and then reaching the effect of power saving.
