Description
Technical field
The present invention relates to a kind of Automatic Neighboring Relation maintenance technology, more particularly, to a kind of Automatic Neighboring Relation measuring method and
System.
Background technology
Demand for services is continuously increased with user with increasing of cell mobile communication systems provider customer's quantity, honeycomb
The scale of network constantly expands, and base station number also increases therewith.For meeting the communication requirement of various communication services, various standards
Cell mobile communication systems constantly deepens cooperating to each other.So, in cellular network, the neighboring BS relationship of cell manages
With safeguard also become day by day loaded down with trivial details work, then operator be especially desired to over pure manual neighboring BS relationship configuration management can
Automatically realize.
Fig. 1 is UTRA system architecture schematic diagram, as shown in figure 1, in general land wireless access (UTRA, Universal
Terrestrial Radio Access) in system, universal land radio access web (UTRAN, Universal
Terrestrial Radio Access Network) include radio network controller (RNC, RadioNetwork
) and the basic network element such as base station (NodeB) Controller.The neighboring BS relationship of the numerous minizones under numerous NodeB, can be with net
The needing and the change of residing wireless environment and dynamic change of network plan optimization.
In UTRA system, the correct neighboring BS relationship in minizone is extremely important for network performance.Neighboring BS relationship is just
Really configuration is to realizing mobile subscriber, user equipment (UE, User Equipment) optimal switching it is ensured that service continuity, realization
Load balancing, capacity allotment, energy-conservation etc. are all quite important.Under past pure manual neighbor cell configuration and layout, network side will in advance
The neighboring BS relationship having configured notifies to UE by system broadcast message or proprietary control message, and UE stores further and utilizes this
A little cell neighboring BS relationship.But, this is probably out-of-date it is impossible to real reflect from the neighboring BS relationship that network side is pre-configured with
Neighboring BS relationship in real time, consequently, it is possible to causing UE mistake to switch, or even call drop, lead to network performance totally to decline.
In UTRA system, third generation partner program (3GPP, The 3rd-GenerationPartnership
Project) in version 10 (Release10), introduce one kind and complete mode (Best Effort based on best endeavors
To do) Automatic Neighboring Relation function (ANRF, Automatic NeighborRelation Functionality).By
Currently, the Automatic Neighboring Relation in version 10 (ANR, AutomaticNeighbor Relation) scheme realize flow process, frame
Structure, and the correlative detail realized determined and open substantially.Fig. 2 be UTRA system in ANRF scheme realize flow process
Figure, as shown in Fig. 2 the ANRF scheme being related in version 10 has borrowed minimum drive test (MDT, Minimize Driving
Test) the thought of technology, the program is also referred to as Log ANR scheme, and idiographic flow comprises the following steps：
Step 201, UE resides in certain cell-of-origin under the RNC of source (Source cell, or referred to as current service cell
Serving cell) in.Source RNC selects certain suitable UE to go to execute a certain class or the measurement times of a few class ANR in cell-of-origin
Business.Here, ANR measuring task type is divided into four basic classes, respectively：UTRA ANR intra-frequency measurement (Intra-frequency
ANR logging), UTRA ANR frequency external pelivimetry (Inter-frequency ANR logging), across LTE ANR measurement
(Inter-RAT LTE ANRlogging), across GSM ANR measures (Inter-RAT GSM ANR logging).
Step 202, source RNC sends to the UE selecting for execution ANRF task before in cell-of-origin and measures control containing ANR
RRC downstream message (DL Message with ANRConfigurations, the protocol specification so far of configuration parameter processed
State, can be this message of Logged MeasurementConfiguration).These ANRF configuration parameters include：ANR
Measurement parameter (ANRlogging duration timer) in limited time, ANR measurement range limits parameter (ANR logging
Detection range), and Intra-frequency ANR logging, Inter-frequency ANR logging,
These four basic ANR measurement types correlations of Inter-RAT LTEANR logging, Inter-RAT GSM ANR logging
Parameter (ANR logging absolute threshold, the ANR logging of cell signal assessment
relativethreshold).UE preserves the configuration parameter of these ANRF, makes with after ANR to be entered into measurement proper states
With.
Step 203, UE is through certain wireless heterogeneous networks (RRC, Radio Resource Control) Signalling exchange
Afterwards, enter into the state of certain suitable ANR measurement, just use the ANRF configuration parameter preserving before to be a certain or classes of
The measurement of adjacent unknown detection cell is prepared.The current protocol specification of state being suitable for doing ANR measurement can be idle mould state
(Idle mode), Acceditation Area level paging state URA_PCH, cell-level paging state Cell_PCH etc..
Step 204, due to the possible mobility of UE itself or other reasonses, UE mono- aspect carries out non-ANR measuring task
Cell measurement task in the related Neighboring Cell List of routine, is that cell reselection is prepared；On the other hand, UE is according to before
ANRF configures, and executes ANRF mono- class or a few class measuring task, and the unknown neighbor meeting log condition is detected cell
(including physical layer information, layer 2 information on physical layer etc.) record ANR log table (ANR Logging within UE
Table in).This record behavior is referred to as ANR Logging or Logging, refers to that UE finishes the record after ANR measurement
Action.When certain neighbor cell in the conventional Neighboring Cell List of UE meets cell re-selection conditions, UE is still according to conventional pattern
In the Target cell in that Neighboring Cell List for the gravity treatment, the interference that can't be measured by ANR is that is to say, that ANR measuring task
It is to attach along with the gravity treatment behavior of UE conventional cell, the cell reselection performance of UE is not subject to ANR measurement to affect, UE executes ANR
Measurement is to do to best endeavors mode (best effort) as much as possible.
Step 205 is it is assumed that UE have selected Target cell and gravity treatment entrance in certain Neighboring Cell List, if UE is in it
There is effective logging content in the ANR table in portion, be just sent to certain RRC of the Target RNC at Target cell place at it
In upstream message, (protocol specification state so far can be specifically RRC Connection Setup Complete, Cell
The message such as Update, URA Update, MeasurementReport), indicate that its ANR measurement result has had and permissible
Reported.
Step 206, alternatively, UE, after certain RRC signaling interaction, has entered into certain and has properly done ANR measurement
The state that result reports, and carry out and report preparation.Protocol specification state so far, uploaded state can be specifically Cell_
DCH, Cell_FACH state.
Step 207, the Target RNC that Target cell is located is by certain RRC downstream message it is desirable to UE carries out ANR measurement knot
Fruit reports.This process is referred to as ANR Logging Results Retrieval.Protocol specification state so far,
Retrieval specifically can be realized by UE Information Request message.
Step 208, according to the request of Target RNC, UE is saved in ANR table before reporting it by certain RRC upstream message
In ANR measurement result.Protocol specification state so far, retrieval specifically can pass through UE Information
Response message is realized.
Step 209, Target RNC according to obtain ANR measurement result, safeguard its related Neighboring Relation Table (NRT,
Neighbor Relation Table).
The Log ANR scheme of above-mentioned UTRA system is carried out based on UE best endeavors mode, former in order to not affect UE
The conventional cell gravity treatment behavior in Neighboring Cell List coming, and UE will not specially open control plane signaling for ANR, goes to carry out ANR survey
Measure reporting of result.This mechanism is favourable for the impact reducing to user service experience, but sometimes influences whether ANR
Performance.Such as, when network is after certain cell is handed down to UE ANR measurement control parameter, UE does not have short time interior entrance can
To execute the effective status of ANR measurement, but UE has been switched to new cell environment so that those ANR storing before measure
Control parameter is not to new cell environment optimal design-aside.Further, when UE itself does not move, general UE does not occur conventional little
Area's gravity treatment behavior, that is, UE reside in original Serving cell for a long time, then corresponding ANR measurement is difficult to capture unknown phase
Adjacent cell.Further, it is in Idle state or the UE moving range of URA_PCH state is wider, if there occurs the gravity treatment of multiple conventional cell,
Also multiple unknown neighbor cells are captured with the ANR measurement that this occurs.But because UE never has up nature
Signaling, so UE can not report the instruction of its stored ANR measurement result, therefore network cannot obtain (Retrieve) this UE
The unknown neighboring BS relationship finding.Above-mentioned several example explanation, existing ANR mechanism usually can not make the ANR that network provides optimization
Control parameter is arranged it is impossible to make network within the time as short as possible, gets the up-to-date unknown neighboring BS relationship of UE discovery, so
In time network neighbor relation can not be adjusted optimize it is impossible in time improve network critical performance parameters (KPI,
KeyPerformance Indicators).
In order to improve the performance that network does the time delay aspect of ANR measurement, network side should issue in ANR measurement control parameter
During process and ANR measurement result report, shorten ANR measurement time delay as much as possible, reduce to user service body simultaneously as far as possible
The impact tested.
