Description
Technical field
The present invention relates to Automatic Neighboring Relation function (ANRF, Automatic Neighbor Relation
Functionality) technology, espespecially a kind of method and system for realizing ANR measurements.
Background technology
With the raising increased with user to demand for services of cell mobile communication systems provider customer's number, cellular network
Scale constantly expand, base station number is on the increase, and the cell mobile communication systems of various standards is constantly deepened to intemperate with one another.
Concomitantly, in cellular network, the neighboring BS relationship management and maintenance of cell become more and more loaded down with trivial details work, then expect the past
Pure manual neighboring BS relationship management can be by system automation.Unexceptionally, UTRA network operators to crave for very much its network little
The neighboring BS relationship in area is realized managing automatically.
Fig. 1 is the system architecture schematic diagram of existing UTRA, as shown in figure 1, in UTRA networks, general land wireless access
Net (UTRAN, Universal Terrestrial Radio Access Network) including radio network controller (RNC,
Radio Network Controller) and base station (NodeB) two kinds of basic network elements.Numerous cells under hundreds of NodeB
Between neighboring BS relationship, can with the network planning optimize needs and residing wireless environment change and dynamically change.
In UTRA networks, the correct neighboring BS relationship in minizone is extremely important to network performance.Such as:Realize mobile using
Family, user terminal (UE) optimal switching, it is ensured that its service continuity help real-time performance load balancing, capacity allotment, energy-conservation etc.
Multipurpose.Under pure manual adjacent area layout, network side by the neighboring BS relationship for having configured in advance pass through system broadcast message or
The proprietary control message of person notified to UE, and UE further stores and utilize the cell neighboring BS relationship that receives.But, it is this come automatic network
The neighboring BS relationship that side configures in advance is probably out-of-date, it is impossible to really reflect real-time neighboring BS relationship, consequently, it is possible to causing UE
Mistake switching, or even call drop reduces network performance.
In UTRA systems, 3GPP versions 10 (Release10) introduce one kind and complete mode (Best based on best endeavors
Effort to do) Automatic Neighboring Relation function (ANRF, Automatic Neighbor Relation
Functionality).The program borrows minimum drive test (MDT, Minimize Driving Test), and abbreviation Log is automatic for technology
Neighboring BS relationship (ANR) scheme, idiographic flow is as shown in Fig. 2 comprise the following steps：
Step 200：UE resides in certain cell-of-origin under the RNC of source (Source cell) or referred to as current service cell
In (Serving cell).Source RNC selects certain suitable UE to perform a certain class or the measurement times of a few classes ANR in cell-of-origin
Business.
Here, ANR measuring task type is divided into basic 4 class：UTRA ANR intra-frequency measurements (Intra-frequency ANR
Logging), UTRA ANR frequencies external pelivimetry (Intra-frequency ANR logging), across LTE ANR measurement (Inter-
RAT LTE ANR logging), and across GSM ANR measurements (Inter-RAT GSM ANR logging).
Step 201：To ANRF tasks carrying UE selected before in cell-of-origin, transmission carries ANR measurement controls to source RNC
The RRC downstream messages (DL Message with ANR Configurations) of configuration parameter processed, such as UTRA ANR measurements
Configuration (Logged Measurement Configuration) message.
Wherein, ANRF configuration parameters include：ANR measures prescribe a time limit parameter (ANR logging duration timer), ANR
Measurement range limit parameter (ANR logging detection range), and with Intra-frequency ANR
Logging, Inter-frequency ANR logging, Inter-RAT LTE ANR logging, Inter-RAT GSM
Parameter (the ANR logging absolute of the related cell signal assessment of the basic ANR measurement types of this 4 kinds of ANR logging
threshold,ANR logging relative threshold).UE preserves the ANRF configuration parameters for receiving, to wait to enter
Use to after ANR measurement proper states.
Step 202：UE is through certain wireless heterogeneous networks (RRC, Radio Resource Control) Signalling exchange
Afterwards, certain state for being suitably executed ANR measurements has been entered into, the ANRF configuration parameters preserved before use are a certain class or several
The measurement of the adjacent unknown detection cell of class is ready.
Current protocol specification, the state for being suitably executed ANR measurements can be Idle state (Idle mode), and Acceditation Area level is sought
Exhale state (URA_PCH), cell-level paging state (Cell_PCH).
Step 203：Due to the possible mobilitys of UE itself or other reasonses, on the one hand UE carries out non-ANR measuring task
Cell measurement task in the Neighboring Cell List of related routine, is that cell reselection is prepared；On the other hand, UE is according to preserving before
ANRF configuration parameters, perform a certain classes of ANRF or a few class measuring task, and the unknown neighbor of record log conditions will be met
Detection cell (including physical layer information, 2 information of layer on physical layer etc.) record (ANR in the ANR log tables inside UE
Logging Table)。
Record behavior in this step is referred to as ANR Logging or Logging, after referring to that UE has performed ANR measurements
Operation of recording.When certain neighbor cell in the conventional Neighboring Cell List of UE meets cell re-selection conditions, UE is still according to existing
Pattern gravity treatment in the Target cell in that Neighboring Cell List, can't be disturbed by ANR measurements, that is to say, that ANR survey
Amount task is that, incidentally along with the gravity treatment behavior of UE conventional cells, the cell reselection performance of UE is not affected by ANR measurements, UE
Perform ANR measurement best endeavors modes (best effort) as much as possible to realize.
Step 204：Assume that UE have selected the Target cell in certain Neighboring Cell List and gravity treatment is entered, if UE is in which
Effective logging contents have been there are in the ANR tables in portion, just certain of the Target RNC at Target cell place have been sent at which
In RRC upstream messages, indicate that its ANR measurement result has possessed and can be reported.
In this step, for indicating that ANR measurement results have possessed and the RRC upstream messages that can be reported can be with
It is：RRC connection establishments complete (RRC Connection Setup Complete) message, and cell update (Cell Update) disappears
Breath, URA renewal (URA Update) message, measurement report (Measurement Report) message,
Step 205：Alternatively, UE is believed through certain wireless heterogeneous networks (RRC, Radio Resource Control)
After order interaction, certain is entered into and has been suitably executed the state that ANR measurement results are reported, and carried out and report preparation.Uploaded state
It can be specifically Cell_DCH, Cell_FACH state.
Step 206：The Target RNC that Target cell is located passes through certain RRC downstream message, it is desirable to which UE carries out ANR measurement knots
Fruit reports.This process is called ANR Logging Results Retrieval, can be UE information request (UE
Information Request) message.
Step 207：According to the request of Target RNC, UE is stored in ANR tables before reporting which by certain RRC upstream message
In ANR measurement results, can be UE information responses (UE Information Response) message.
Step 208：Target RNC safeguards its related Neighboring Relation Table NRT according to the ANR measurement results for obtaining
(Neighbor Relation Table)。
In the Log ANR schemes of existing UTRA systems shown in Fig. 2, step 203 is a crucial step.For in PCH states
The UE of ANR measurements is performed, the discontinuous reception in cell-of-origin is using the undefined UTRAN of PCH states discontinuously reception cycle is empty
Idle section (UTRAN DRX Cycle DRX Off), carries out ANR measurements to adjacent unknown cell, once UE measures unknown phase
Adjacent detection cell meets certain record condition, is just recorded under (log)；For the UE that ANR measurements are performed in Idle states,
In cell-of-origin, using the undefined core net of Idle states, discontinuous reception of the same area specifically discontinuously in the reception cycle be not idle
Period (CN domain specific DRX cycle Off), ANR measurements are carried out to adjacent unknown detection cell, once UE is surveyed
Measure unknown neighbor cell and meet certain record condition, just recorded.Either PCH states or Idle states do not connect
Discontinuous reception idle period (DRX Cycle Off, when hereinafter referred to as DRX Cycle Off are idle in the continued access receipts cycle
Section) all it is long, UE does not carry out the reception of any control data of this Serving cell or user data, institute in this period
So that UE fully can be measured to adjacent known cell physical layer (L1) signal and be assessed with cell quality.
In ANR measurements, except to known neighbor cell measurement, UE is also needed to adjacent unknown detection cell physical signalling
Measure and assess with cell quality, if necessary, in addition it is also necessary to the System information block (SIB) to meeting the detection cell of log conditions
It is read out, to obtain necessary layer 2 (L2) information such as cellular global identity etc..As it was previously stated, UE enter PCH or
After Idle states, no longer receive from RNC except paging Paging, any control data outside system message, therefore, survey with ANR
The related control configuration information of amount is all to be sent by RNC before ANR measurements start and preserved by UE, and then UE is in accordance with original
While there are cell reselection rules, reasonably ANR measurements are carried out using these ANR configuration parameters, all ANR measurements are local by UE
Scheduling, is carried out in the form of best endeavors are done, it is impossible to is sacrificed the success rate that UE receives Paging, is not destroyed UE to conventional adjacent area
The original rule of cell reselection and behavior in list, then, the Log ANR schemes of existing UTRA systems are likely to result in following asking
Topic：
Network may be assigned in frequency simultaneously, frequency outer (multiple frequencies), across LTE and the class in tetra- class ANR tasks of GSM or
Person's multiclass (this is the problem that RNC assigns the realization of ANR parameter configurations).If network only issues a class ANR task every time, then UE
Perform in the ANR measurements of single type, scheduling is very clear and definite using the mode of DRX Cycle Off idle periods, such as：Network is only
It is configured with to carrying out ANR measurements on outer certain Frequency point of frequency, then UE is by except for known neighbor cell in conventional Neighboring Cell List
Other DRX Cycle Off idle periods outside the DRX Cycle Off idle periods of measurement, for that Frequency point
ANR is measured, i.e., the search of unknown cell is carried out on that Frequency point；
If network sends multiclass ANR task per subtask simultaneously, different UE might have different ANR measurement schedulings
Processing mode.Such as mode 1：According to the UMTS different frequent points priority level different with LTE/GSM frequencies, from highest priority
Frequency starts ANR measurements, and after having performed a period of time, (possibly absolute time length or UE have searched N number of adjacent
Unknown cell), then the ANR tasks on low priority frequency are performed, this is a kind of mode of UE scheduling ANR measurements.Mode 2：UE
Interweave each generic task of ground execution, i.e., perform ANR measurements in frequency first with N number of DRX cycle, and M DRX cycle of recycling is performed
The outer ANR measurements of frequency, recycle L DRX cycle to perform ANR measurements across GSM etc., after a large period, repeat it
Front measurement execution sequence, this is the mode of another kind of UE scheduling ANR measurements.Mode 3：According to the original conventional Neighboring Cell List of UE
Interior cell reselection tendentiousness, performs certain class ANR and measures, such as：When in UE frequencies, cell reselection measurement is triggered, just using all
Available DRX cycle Off idle periods, carry out ANR measurements to the unknown cell in frequency.When across the GSM cell gravity treatment measurements of UE
When being triggered, all available DRX cycle Off idle periods are just utilized, ANR surveys are carried out to the unknown cell of gsm system
Amount, by that analogy；
As how UE dispatches DRX Cycle Off idle periods go to perform ANR measurements, be a relative UE local row
If network does not know how UE dispatches DRX cycle Off idle periods and go to perform ANR measurements completely, and less to know
How long times of the UE in long DRX cycle Off idle period states are possessed can continue on earth, then, network side just cannot be pre-
ANR measured bottom and was able to record that log to which new neighboring BS relationship to UE after a period of time phase, that is to say, that current ANR
The performance of scheme is only a kind of work of best endeavors (Best Effort).Such as：May be different in certain region, network
Neighboring BS relationship poor (leakage, mispairing) between frequency cells, and preferable with minizone neighboring BS relationship in frequency, then network should have and incline
Tropism ground is used for the measurements of the ANR between different frequency, the fully real institutes of record log more DRX Cycle Off idle periods
The unknown neighbor cell outside frequency for needing, so as to ANR measurement results have certain mass to ensure.
But, as existing DRX Cycle Off idle periods of how dispatching go to perform ANR measurements, it is a relative UE
Local behavior, therefore, more DRX Cycle Off idle periods can not be used for the ANR between different frequency and be surveyed by network side
Amount, it is impossible to preferably fully record the unknown neighbor cell outside the really necessary frequencies of log, so as to cannot ensure ANR measurement results
There is certain mass to ensure.
Based on foregoing description, the performance of log is measured to improve ANR, do the ANR measurements of quality assurance.UE should be able to
It is enough more targetedly to do ANR measurement log in the case where certain network is expected, rather than pure Best Effort enter
OK.The present invention provides a kind of mechanism, network is preferably being coordinated UE and surveyed to different type ANR by ANR configuration parameters
Amount behavior.

Step 300：Before UE performs ANR measurements, network side will include joins to different type ANR measurement scheduling relevant control
Several ANR measurement control configuration parameters, are sent to UE.
Wherein, it is as shown in table 1 to the cell body structure of different type ANR measurement scheduling associated control parameters.
Table 1
In table 1,4 sub- cells are that frequency is outer, in frequency, across LTE and across GSM cell proportions sum should be 100%.
Ratio value shown in table 1 is merely to illustrate that and that as informative the span specifically enumerated can be other
Value.In table 1, a cycle length of different type ANR measurement gives tacit consent to the DRX Cycle that can be.
It should be noted that the sub- cell in table 1 can also take other forms, but the core concept of self-confident remote design
It is：Network is to, in frequency, frequency is outer (multiple different frequent points), across LTE (multiple different frequent points), across GSM (multiple different frequent points) this 4 class
ANR basic tasks, carry out different priority establishments according to the desirability of network, or to measuring for different type ANR
The usage amount of DRX cycles Off idle periods carry out different weights configurations, such network just can realize tendentiousness
