Description
Technical field
The present invention relates to the communications field, in particular to a kind of report method and device of neighbor cell relation measurement result.
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.As shown in Figure of description 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and utilizes these to receive.But this neighboring BS relationship configured in advance from network side may be out-of-date, can not really reflect real-time neighboring BS relationship, thus UE mistake may be caused to switch, and even call drop, network performance totally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.By the moment of patent drafting of the present invention, although the ANRF final scheme details of UTRA is not also determined, scheme basic procedure framework has been determined and is disclosed.Refer to Figure of description 2 of the present invention.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 2info 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:
Because based on the Log ANR mode of cell reselection, usually the instruction of ANR logs result and reselection target cell Target cell can only be reported, instead of cell-of-origin Source cell.If Target cell and cell-of-origin be in same RNC administrative under, that problem is also little, because RNC inside has a set of mechanism can go to safeguard neighboring BS relationship based on ANR Logs.But, when reselection target cell and cell-of-origin are under different RNCs, even Target cell is in another one system (as LTE, GSM) time, the source RNC at place, cell-of-origin is in order to obtain the up-to-date unknown neighboring BS relationship of cell-of-origin, Iur interface between source RNC and Target RNC must coordinate, and Target RNC passes to Source RNC with some form the ANR logs that UE reports in Target cell.This method is to being feasible across RNC, and cost is more Iur Signalling exchange; But it is infeasible for cross-system disappearance, because there is no direct interface between the network controller of different system, so UTRA system such as to only have again get back to the UTRA community of oneself at the UE, the ANR Logs that UE stores could be obtained, and thisly report time delay to be very large sometimes, so safeguard that uncertainty is brought in adjacent area to RNC.

Embodiment 3
The present embodiment provides a kind of report method of neighbor cell relation measurement result, comprises the steps:
Initialization: alternatively, increases UE is forced to indicate and report ANR logs ability in cell-of-origin, after enabling the clear and definite UE of network have this ability, just can assign the order that UE directly carries out ANRlogs instruction in cell-of-origin and reports.
Step 1: before UE performs ANRF surveying record task, comprises the parameter shown in following table or cell in the control configuration parameter that source RNC is correlated with at the ANRF sent to UE alternatively.
Table 1
UE receives and preserves above-mentioned parameter respectively in local variable Enable_Source_ANR and Threshold_Source_ANR.This Two Variables reset condition is Null.
Step 2: the UE being in PCH state utilizes PCH state undefined DRX cycle to measure adjacent unknown cell in cell-of-origin, once UE measures unknown neighbor cell meet certain record condition, just got off by its log.The UE being in Idle state utilizes Idle state undefined DRX cycle to measure adjacent unknown cell in cell-of-origin, once UE measures unknown neighbor cell meet certain record condition, just got off by its log.Attention: meanwhile, UE is also neighbor cell measurement in cell reselection and the Neighboring Cell List for preparing doing conventional.So likely, what does not all have Log to arrive to UE, has just gone from cell-of-origin gravity treatment to Target cell, so Target cell just becomes new cell-of-origin.Now Enable_Source_ANR and Threshold_Source_ANR variate-value still retains, until RNC reconfigures them.
Step 3: if the Enable_Source_ANR=TRUE of UE and effective Log entry number of having recorded are greater than or equal to Threshold_Source_ANR and other any possible triggering UE do the factor that neighboring BS relationship measurement result reports all does not work to cell-of-origin. the UE for PCH state: the cycle cell update timer expired forcing UE natively to have so immediately, carries out the more new technological process (Cell Update) of cell-of-origin; UE for Idle state: force UE to carry out the RRC connection request flow process (RRC Connection Request) of cell-of-origin so immediately.Similarly, also can define the local a kind of new trigger event of UE, this event is determined to produce by the ANR Log behavior outcome of UE, and can trigger UE and carry out cell update flow process or RRC wireless request flow process.
Step 4:UE, by cell update flow process or RRC wireless request flow process, reports ANR logs to record result in cell-of-origin instruction.If ANR Logs number is comparatively large, be not suitable for being reported by common signal channel at public connected state Cell_FACH, RNC can consider to set up wireless link, allows UE enter proprietary state Cell_DCH and is reported by dedicated channel.
Step 5: after successfully reporting ANR Logging result, UE empties local variable Enable_Source_ANR=Null, Threshold_Source_ANR=Null.
By the methods of above-mentioned about beamsplitter terminal to reporting neighboring cell, cell-of-origin relation, network can report behavior by control ANR measurement logging more effectively, but cost increases certain signaling simultaneously.Merit attention: network requirement UE is more careful behavior to reporting neighboring cell, cell-of-origin relation, only have when being necessary, such as UE is in that to switch KPI index across RNC region or a certain region of Network finding very poor, when needing to make rapidly the adjustment of corresponding neighboring BS relationship.
Embodiment 4,
Fig. 5 is the another kind of flow chart of the report method according to embodiment of the present invention neighbor cell relation measurement result, 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, selected to go to perform ANR task by the source RNC at place, cell-of-origin, and require to report ANR result as early as possible in cell-of-origin.
Step 50l: source RNC by issuing physical channel reallocation message (Physical Channel Reconfiguration), the control configuration parameter that ANR is relevant sends to UE, comprise the cell of two shown in table 1 in embodiment 3 and assignment is as follows: Enabler for ANR reporting in source cell=TRUE, Threshold NO.log entry for ANR reporting insource cell=2.UE preserves them, so Enable_Source_ANR=TRUE and Threshold_Source_ANR=2.
Step 502:UE while do neighbor cell measurement in the Neighboring Cell List prepared for cell reselection, does the measurement of the unknown neighbor cell that ANR is correlated with in Cell_PCH state.Along with time lapse, successively find and have recorded 2 unknown neighbor cells and corresponding Entry in local ANR Log shows.Now UE does not find that in the community of himself Neighboring Cell List cell reselection is done in extraordinary Target cell.
Step 503: in this process, other any possible triggering UE do the factor that neighboring BS relationship measurement result reports and do not work to cell-of-origin.So the cycle cell update timer expired that UE just forces UE natively to have immediately, carry out the more new technological process (Cell Update) of cell-of-origin.
Step 504:UE reports ANR logs to record result by cell update flow process in cell-of-origin instruction.Because logs number is not very large, so UE is only reported by common signal channel in Cell_FACH state.
Step 505: after successfully reporting ANR Logging result, UE empties local variable Enable_Source_ANR=Null, Threshold_Source_ANR=Null.
Embodiment 5
Fig. 6 is another flow chart of the report method according to embodiment of the present invention neighbor cell relation measurement result, the scene of the present embodiment 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 Idle state, selected to go to perform ANR task by the source RNC at place, cell-of-origin, and require to report ANR result as early as possible in cell-of-origin.
Step 601: source RNC is by issuing RRC connection release message (RRC Connection Release), the control configuration parameter that ANR is relevant sends to UE before UE enters Idle state, comprise the cell of two shown in table 1 in embodiment 3 and assignment is as follows: Enabler for ANR reporting in source cell=TRUE, Threshold NO.log entry for ANRreporting in source cell=4.UE preserves them, so Enable_Source_ANR=TRUE and Threshold_Source_ANR=4.
Step 602:UE while do neighbor cell measurement in the Neighboring Cell List prepared for cell reselection, does the measurement of the unknown neighbor cell that ANR is correlated with in Idle state.Along with time lapse, successively find and have recorded 4 unknown neighbor cells and corresponding Entry in local ANR Log shows.Now UE does not find that in the community of himself Neighboring Cell List cell reselection is done in extraordinary Target cell.
Step 603: in this process, other any possible triggering UE do the factor that neighboring BS relationship measurement result reports and do not work to cell-of-origin.So UE just forces the RRC connection request flow process (RRC ConnectionRequest) of carrying out cell-of-origin immediately.
Step 604:UE reports ANR logs to record result by RRC connection request flow process in cell-of-origin instruction.Because logs number is comparatively large, so RNC determines to set up wireless link, allow UE enter proprietary state Cell_DCH and reported by dedicated channel.
Step 605: after successfully reporting ANR Logging result, UE empties local variable Enable_Source_ANR=Null, Threshold_Source_ANR=Null.
As can be seen from the above description, present invention achieves following technique effect:
Pass through the present invention, terminal UE is meeting under predetermined condition to cell-of-origin report measurement results, solve when reselection target cell and cell-of-origin are under different RNCs, report the problem that the time delay of ANRlogs result is large, and then reach and can retrain after UE finishes effective ANR surveying record, indicate and the effect reporting ANRLogs time delay little to cell-of-origin, particularly in the border of UE in RNC overlay area, source and Target RNC overlay area, or UE is by when cell reselection to other system.
