Description
Technical field
The present invention relates to the communications field, in particular to a kind of report method and device of adjacent cell relations 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 enlarges, and the base station number is on the increase, and the cell mobile communication systems of various standards is constantly deepened co-operation each other.Together everywhere, the neighboring BS relationship of sub-district administers and maintains in the cellular network becomes more and more loaded down with trivial details work, so operators expect that in the past pure manual neighboring BS relationship management can be by system automation.
Unexceptional ground, UTRA network operation merchant craves for the neighboring BS relationship of its network cell and realizes management automatically very much.Shown in Figure of description 1; In the UTRA network; UTRAN (Universal Terrestrial Radio Access Network, universal land radio access web) comprises RNC (Radio Network Controller, radio network controller) and two kinds of basic network elements of NodeB (base station).The neighboring BS relationship of numerous minizones under the hundreds of NodeB, the needs that can optimize along with the network planning and the variation of wireless environment of living in and dynamically change.
In the UTRA network, the correct neighboring BS relationship in minizone is extremely important to network performance.Such as: realize the mobile subscriber, terminal UE is optimum to be switched, and guarantees its service continuity, helps network to realize load balancing, capacity allotment, the energy-conservation multipurpose that waits.Under the pure manual adjacent area layout of past, the neighboring BS relationship that network side will configure is in advance notified to terminal UE through system broadcast message or proprietary control messages, and UE further stores and utilize these sub-district neighboring BS relationship of receiving.But this neighboring BS relationship that configures in advance from network side possibly be out-of-date, can not really reflect real-time neighboring BS relationship, thereby possibly cause the UE mistake to switch, even call drop, and network performance totally descends.
In the UTRA system, 3GPP introduces Automatic Neighboring Relation function (Automatic Neighbor Relation Functionality is called for short ANRF) in version 10 (Release10) plan.By the moment that patent of the present invention is write, though the ANRF final scheme details of UTRA does not confirm that also scheme basic procedure framework has been confirmed and be open.See also Figure of description 2 of the present invention.This scheme has been used the thought of minimum drive test MDT technology (Minimize Driving Test), is the mode based on Log, is called for short Log ANR scheme, and the idiographic flow step is explained as follows referring to Fig. 2:
S201:UE resides in the inside, certain cell-of-origin under the RNC of source (Source cell).Source RNC selects certain suitable terminal UE to go to carry out a certain type or several types of ANRF measuring task in the 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 or the like.
S202: source RNC carries out UE to selected before ANRF task in the cell-of-origin, sends certain and contains the RRC downstream message (DL Message with ANR Configurations) that ANRF measures the control configuration parameter.These ANRF configuration parameters possibly comprise: the adjacent unknown cell of the frequently interior Intra-frequency of UTRA is detected, and/or the adjacent unknown cell of the outer Inter-frequency of UTRA frequency is detected, and/or detect striding the adjacent unknown cell of LTE system (Inter-LTE); And/or to striding the adjacent unknown cell detection of gsm system (Inter-GSM); These 4 kinds basic ANRF measure the relevant necessary configuration information of type, obtain the measurement event dependent threshold such as the measurement of carrying out which physical layer signal information; Threshold value; Biasing, neural buffering etc. also comprise the obtaining of layer 2 information of carrying out on which physical layer (Layer 2info acquistion) etc. alternatively.UE preserves the configuration parameter of these ANRF, proceeds its other necessary communication behaviors.
S203:UE is through after certain RRC (Radio Resource Control) Signalling exchange; UE has entered into the state that certain suitable ANRF of being measures, the ANRF configuration parameter of preserving before just using be a certain or the measurement of several types adjacent unknown detected cells ready.Being fit to do the state that ANRF measures possibly be Idle state Idle, paging attitude URA_PCH, Cell_PCH or the like.
S204: because possible mobility or the other reasons of UE itself, UE carries out the interior cell measurement task of Neighboring Cell List of the relevant routine of non-ANRF measuring task on the one hand, for district reselecting is prepared; On the other hand; UE disposes according to ANRF before; Carry out the ANRF measuring task, and (comprising physical layer information to the measurement result that satisfies certain condition, alternatively: layer 2 information on the physical layer) be recorded in the inner ANR table of UE (ANR Logging Table).We are called for short ANR Logging or Logging this record behavior, are core concepts of MDT technology.When the district reselecting condition is satisfied in certain sub-district in the conventional Neighboring Cell List of UE; UE is still according in the past the pattern gravity treatment Target cell in that Neighboring Cell List; Can't receive the interference of ANRF measuring task, that is to say that the ANRF measuring task is the subsidiary conventional district reselecting behavior of UE that is accompanied by.
S205: when Target cell in UE has selected certain Neighboring Cell List and gravity treatment get into; If the UE ANR of portion has within it had effective logging content in showing; Just send in certain RRC upstream message of Target RNC at Target cell place, indicate its ANRF measurement result to have and can report at it.
S206:UE is through after certain RRC (Radio Resource Control) Signalling exchange, and UE has entered into the state of certain the suitable ANRF of being reporting measuring result, and carries out and report preparation.
S207: the Target RNC at Target cell place requires UE to carry out the ANRF reporting measuring result through certain RRC downstream message.We claim that this process is ANR Logging Results Retrieval.
S208: according to the request of Target RNC, UE is kept at the ANRF measurement result in the ANR table before reporting it through certain RRC upstream message.
S209: Target RNC is safeguarded the Neighboring Relation Table NRT (Neighbor Relation Table) that it is relevant according to the ANRF measurement result that obtains.
The Log ANR scheme of above-mentioned UTRA system, though be a kind ofly to realize relatively easily and UE is served originally that the mobile behavior influence is less owing to adopted the thought of MDT, thus natural succession its many shortcomings, as follows:
Because based on the Log ANR mode of district reselecting, can only and report gravity treatment Target cell Target cell ANR logs result indication usually, rather than cell-of-origin Source cell.If Target cell and cell-of-origin are under same RNC has jurisdiction over, that problem is also little, because RNC inside has a cover mechanism to remove to safeguard neighboring BS relationship based on ANR Logs.But; When gravity treatment Target cell and cell-of-origin are under the different RNCs; Even Target cell is in the another one system, and (like LTE, in the time of GSM), 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 cooperate, and Target RNC passes to Source RNC to UE at the ANR logs that Target cell reports with certain form.This method is feasible to striding RNC, and cost is more Iur Signalling exchange; But it is infeasible for interdepartmental system disappearance; Because there is not direct interface between the network controller of different system; So the UTRA system such as has only to get back to the UTRA sub-district of oneself once more at UE; Could obtain the ANR Logs of UE storage, and this to report time-delay be very large sometimes, so safeguard that to RNC the adjacent area brings uncertainty.

Embodiment 3
Present embodiment provides a kind of report method of adjacent cell relations measurement result, comprises the steps:
Initialization: alternatively, increase UE is compelled to indicate and report ANR logs in the cell-of-origin ability, make network can clear and definite UE have this ability after, just can assign UE directly carries out the ANRlogs indication and reports in the cell-of-origin order.
Step 1: before UE carried out ANRF surveying record task, source RNC comprised parameter shown in the following table or cell alternatively in the relevant control configuration parameter of the ANRF that sends to UE.
Table 1
UE receives and preserves above-mentioned parameter respectively in local variable Enable_Source_ANR and Threshold_Source_ANR.These two variable reset conditions are Null.
Step 2: the UE that is in the PCH attitude utilizes the undefined DRX cycle of PCH attitude that adjacent unknown cell is measured in the cell-of-origin, satisfy certain record condition in case UE measures unknown neighbor cell, just its log is got off.The UE that is in the Idle attitude utilizes the undefined DRX cycle of Idle attitude that adjacent unknown cell is measured in the cell-of-origin, satisfy certain record condition in case UE measures unknown neighbor cell, just its log is got off.Attention: meanwhile, UE is neighbor cell measurement in doing the conventional Neighboring Cell List of preparing for district reselecting also.So possible, UE what do not have Log to arrive, just from the cell-of-origin gravity treatment gone to Target cell, so Target cell just becomes new cell-of-origin.This moment, Enable_Source_ANR and Threshold_Source_ANR variate-value still kept, and reconfigured them up to RNC.
Step 3: all do not work if the Enable_Source_ANR=TRUE of UE and effective Log entry number of having write down are greater than or equal to the factor that Threshold_Source_ANR and other any possible triggering UE do the neighboring BS relationship reporting measuring result to the cell-of-origin. for the UE of PCH attitude: the cycle cell update timer expired that forces UE just to have originally so immediately, carry out the more new technological process (Cell Update) of cell-of-origin; UE for the Idle attitude: 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 incident is produced by the ANR Log behavior outcome decision of UE, and can trigger UE and carry out cell update flow process or RRC wireless request flow process.
Step 4:UE is through cell update flow process or RRC wireless request flow process, and indication reports ANR logs record result in the cell-of-origin.If ANR Logs number is bigger, be not suitable for reporting through common signal channel at public connected state Cell_FACH, RNC will consider and sets up Radio Link, lets UE get into proprietary attitude Cell_DCH and reports through dedicated channel.
Step 5: after successfully reporting ANR Logging result, UE empties local variable Enable_Source_ANR=Null, Threshold_Source_ANR=Null.
Through the methods of above-mentioned about beamsplitter terminal to cell-of-origin reporting neighboring cell relation, network can be controlled ANR measurement logging more effectively and report behavior, but cost is to increase certain signaling simultaneously.Merit attention: network requirement UE is more careful behavior to cell-of-origin reporting neighboring cell relation; Have only when being necessary; Be in such as UE and stride RNC zone or network to find that the KPI index is switched in a certain zone very poor, when need make corresponding neighboring BS relationship adjustment rapidly.
Embodiment 4,
Fig. 5 is the another kind of flow chart according to the report method of the adjacent cell relations measurement result of the embodiment of the invention; The scene of present embodiment is that certain possesses the UE of ANR ability (Source cell) is in the Cell_DCH data transmission state in certain cell-of-origin; DTD gets into the Cell_PCH state then; Source RNC by the place, cell-of-origin selects to go to carry out the ANR task, and requirement reports ANR result as early as possible in the cell-of-origin.
Step 50l: source RNC is through issuing physical channel reallocation message (Physical Channel Reconfiguration); The control configuration parameter relevant ANR sends to UE; Comprise among the embodiment 3 that two cells shown in the table 1 and assignment are following: 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 is neighbor cell measurement in the Cell_PCH attitude is being done the Neighboring Cell List of preparing for district reselecting on one side, Yi Bian doing the measurement of the relevant unknown neighbor cell of ANR.Along with time lapse, successively find and write down 2 unknown neighbor cells and corresponding Entry in local ANR Log table.This moment, UE did not find that in the sub-district of himself Neighboring Cell List extraordinary Target cell does district reselecting.
Step 503: in this process, the factor that other any possible triggering UE do the neighboring BS relationship reporting measuring result to the cell-of-origin does not all work.So the cycle cell update timer expired that UE just forces UE just to have originally immediately carries out the more new technological process (Cell Update) of cell-of-origin.
Indication reports ANR logs record result to step 504:UE in the cell-of-origin through the cell update flow process.Because the logs number is not very big, so UE only reports through common signal channel in the Cell_FACH attitude.
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 according to the report method of the adjacent cell relations measurement result of the embodiment of the invention; The scene of present embodiment is that certain possesses the UE of ANR ability (Source cell) is in the Cell_DCH talking state in certain cell-of-origin; End of conversation gets into the Idle state then; Source RNC by the place, cell-of-origin selects to go to carry out the ANR task, and requirement reports ANR result as early as possible in the cell-of-origin.
Step 601: source RNC is through issuing RRC connection release message (RRC Connection Release); The control configuration parameter relevant ANR sends to UE before UE gets into the Idle attitude; Comprise among the embodiment 3 that two cells shown in the table 1 and assignment are following: 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 is neighbor cell measurement in the Idle attitude is being done the Neighboring Cell List of preparing for district reselecting on one side, Yi Bian doing the measurement of the relevant unknown neighbor cell of ANR.Along with time lapse, successively find and write down 4 unknown neighbor cells and corresponding Entry in local ANR Log table.This moment, UE did not find that in the sub-district of himself Neighboring Cell List extraordinary Target cell does district reselecting.
Step 603: in this process, the factor that other any possible triggering UE do the neighboring BS relationship reporting measuring result to the cell-of-origin does not all work.So UE just forces the RRC connection request flow process (RRC Connection Request) of carrying out the cell-of-origin immediately.
Indication reports ANR logs record result to step 604:UE in the cell-of-origin through RRC connection request flow process.Because the logs number is bigger,, lets UE get into proprietary attitude Cell_DCH and report through dedicated channel so Radio Link is set up in the RNC decision.
Step 605: after successfully reporting ANR Logging result, UE empties local variable Enable_Source_ANR=Null, Threshold_Source_ANR=Null.
From above description, can find out that the present invention has realized following technique effect:
Through the present invention; Terminal UE is satisfying under the predetermined condition to cell-of-origin reporting measurement result; Solved when gravity treatment Target cell and cell-of-origin and be under the different RNCs; Report ANRlogs result's big problem of delaying time, so reached can retrain UE and finish effective ANR surveying record after, to the cell-of-origin indication and report the little effect of ANRLogs time-delay; Particularly when UE in the border of RNC overlay area, source and Target RNC overlay area, perhaps UE is about to district reselecting time the other system.
