Description
Technical field
The present invention relates to the communication technology, more particularly to a kind of RNTI distribution methods and device.
Background technology
In LTE-A（Long Term Evolution Advanced, enhanced Long Term Evolution）In system, CA is introduced
（Carrier Aggregation, carrier aggregation）Technology, system can be by the CC of multiple small bandwidth（Component
Carrier, member carrier）Condense together, so as to obtain bigger system transmission bandwidth and Geng Gao peak data transmission speed
Rate.
In the access network of lte-a system, usually using RNTI（Radio Network Temporary Identity,
Radio Network Temporary Identifier）To address UE（User Equipment, terminal）, realize network to UE control and between the two
Data transfer.Various RNTI purposes and value or span is listed in agreement, but does not provide RNTI distribution
Method.
Specifically, CA technologies are introduced in lte-a system, with LTE（Long Term Evolution, Long Term Evolution）
Member carrier is base unit, and bigger transmission belt is obtained by way of the member carrier of multiple small bandwidth is condensed together
It is wide.Participating in the bandwidth of each member carrier of polymerization be able to can also be differed with identical.
In CA systems（Apply the lte-a system of CA technologies）In, for each UE, it may be simultaneously present multiple services small
Area, UE serving cell is divided into PCell（Primary Cell, main serving cell）And SCell（Secondary Cell, auxiliary clothes
Business cell）Two classes, wherein PCell are certainly existed, and it inherits the property of serving cell in LTE, and each UE only has 1 PCell；
And SCell only undertakes data-transformation facility merely as additional resource, base station can be configured according to being actually needed for UE for UE
One or more SCell.PCell and SCell herein is defined from UE angle, and the single logic for network side is small
Area, it can be both some UE PCell, be other UE SCell again.
In the access network of LTE/LTE-A systems, UE is addressed using RNTI, realize network to UE control and both
Between data transfer.RNTI is divided into many kinds according to purposes, and various RNTI purposes and addressing range is as shown in table 1.
RNTI classification in table 1LTE/LTE-A systems
Wherein, Temporary C-RNTI are served only for random access procedure, are the temporary marks distributed from PCell to UE.
After random access procedure terminates, if UE is successfully accessed to some cell, distinguishes the following two kinds situation and be respectively processed：
If effective C-RNTI is not present before UE, Temporary C-RNTI turn into C-RNTIs of this UE in this cell；Such as
There is effective C-RNTI before fruit UE, then UE still uses original C-RNTI, now Temporary C-RNTI are dropped.
Therefore, in the random access procedure, network side needs distribution Temporary C-RNTI.In addition, in handoff procedure, switching mesh
Mark cell needs to distribute the C-RNTI used in this cell for UE.When UE is successfully accessed to switch mesh via random access procedure
When marking cell, UE uses the C-RNTI, the C-RNTI used before discarding that Target cell is distributed.
RNTI represents that various RNTI value or span is as shown in table 2 using 16 integers.
Table 2RNTI value
For RA-RNTI, calculation formula is given in LTE-A MAC protocols TS36.321.Can based on the calculation formula
Know, RA-RNTI is corresponded with each bar PRACH that place cell is configured in single radio frames, can be calculated based on formula
The corresponding RA-RNTI of every PRACH of configuration specific value in each radio frames.
UE uses identical C-RNTI for all serving cells.
The distribution method of RNTI values is not specified by agreement.For M-RNTI, P-RNTI and SI-RNTI, because it takes
Value is unique, so allocation algorithm need not be introduced；For RA-RNTI, because its value can be based on formula as defined in agreement and calculate,
So without introducing allocation algorithm.For remaining RNTI classifications, including C-RNTI, SPS C-RNTI, Temporary C-
RNTI, TPC-PUCCH-RNTI and TPC-PUSCH-RNTI, it is desirable to be able to UE is addressed in cell range using the RNTI, are seeking
During location, for C-RNTI, SPS C-RNTI and Temporary C-RNTI, it is necessary to be addressed using single RNTI in cell range
Single UE；For TPC-PUCCH-RNTI and TPC-PUSCH-RNTI, it is necessary to address one in cell range using single RNTI
Single UE in the individual UE set specified, this UE set reuses other information and is addressed.Therefore, in cell range, pin
Different UE or UE is gathered, the RNTI values of distribution must be different, to ensure the correctness of addressing.For CA systems,
Because UE uses identical C-RNTI in all serving cells, each serving cell is likely to need to be based on this C-
RNTI addresses this UE, so not only needing to ensure this C-RNTI uniqueness in the range of UE PCell, in addition it is also necessary in UE institute
There is the uniqueness for ensureing this C-RNTI in the range of serving cell.
In summary, in CA systems, for C-RNTI, SPS C-RNTI, Temporary C-RNTI, TPC-PUCCH-
RNTI and TPC-PUSCH-RNTI, particularly with C-RNTI, it is necessary to preferably RNTI distribution methods, to ensure to UE or UE set
The correctness of addressing.
At present, also without suitable RNTI distribution methods, therefore, for C-RNTI, SPS C-RNTI, Temporary C-
The RNTI classifications such as RNTI, TPC-PUCCH-RNTI and TPC-PUSCH-RNTI, may be due to repeating to divide when carrying out RNTI distribution
Correctness with influence UE addressing, if confirming one by one in every sub-distribution, whether the RNTI is unique, influences RNTI allocative efficiencies.

Embodiment
The embodiment of the present invention provides a kind of RNTI distribution methods and device, to the available RNTI of all cells in set of cells
The intersection of sets collection of value is divided, and obtains multiple subsets, and each subset is a RNTI set, is divided when needing progress RNTI
Timing, it is only necessary to according to RNTI types, RNTI is distributed for user equipment from the corresponding RNTI set in current area, it is only necessary to from
The RNTI that determining unassigned RNTI in RNTI set can ensure that user obtains is single subdistrict or multiple cell ranges
It is interior unduplicated, so as to improve RNTI allocative efficiency, improve the correctness of UE addressing.
As shown in figure 1, RNTI distribution methods provided in an embodiment of the present invention, including：
Step S101, determine the Radio Network Temporary Identifier RNTI types that user equipment is asked；
Step S102, from RNTI corresponding with the current area belonging to user equipment and corresponding with RNTI types set in be
User equipment distribute RNTI, wherein, corresponding RNTI collection be combined into in the set of cells comprising current area all cells can
With the intersection of sets collection of RNTI values divide obtained subset, and there is corresponding RNTI set in the set of cells not
Two completely the same cells.
Due to when needing to distribute RNTI to user equipment, as long as according to RNTI types, from the corresponding RNTI in current area
RNTI is distributed for user equipment in set, so only needing to determine unassigned RNTI in from RNTI gathering, you can protect
The RNTI that card user equipment is obtained is unduplicated in single subdistrict or multiple cell ranges, it is ensured that the correctness of addressing,
Meanwhile, without judging that each RNTI, whether with or if appropriate for use, improves RNTI allocative efficiencies successively.
Certainly, distribution RNTI gathers, it is necessary to predefine RNTI by this way, then, it is necessary in advance to set of cells
In the intersection of sets collection of available RNTI values of all cells divide and obtain subset, in set of cells all cells can
Divide obtaining subset with the intersection of sets collection of RNTI values, specifically include：
According to the cooperation relation of each minizone, set of cells is determined；
To each set of cells, the intersection of sets collection of the available RNTI values of all cells in set of cells is determined；
Common factor progress is divided and obtains at least two subsets.
For two cell Cell in networkiAnd Cellj, it is assumed that CelliFor UEiPCell, then CelljWhether can be with
It is configured to UEiSCell, it is necessary to according to CelliAnd CelljRelative Network topology location, and OAM（Operation and
The logic entity of Network Management Function is realized in Maintenance, operation and maintenance）Configuration determine.If CelljCan be with
It is configured to UEiSCell, then it is follow-up to claim CelljFor CelliCA cells.If CelljFor CelliCA cells, or
CelliFor CelljCA cells, or CelliAnd CelljCA cells, then follow-up herein to claim Cell each otheriAnd CelljBetween deposit
In CA cooperation relations.
LTE-A network for deploying CA characteristics, OAM can be by all cells in this network according to certain strategy
It is divided into different set of cells.In each set of cells, some cell Cell is arbitrarily takeni, it all with this set of cells
There is CA cooperation relations between some other or multiple cells.The strategy that OAM is used can be closed according to the geographical position of cell
Two or more cells by same base station or the management of several adjacent base stations are constituted a set of cells by system.
All set of cells determined for OAM, it is assumed that some set of cells Cell_SetiIn the number of cells that includes be
Ni.For the arbitrary cells Cell in this set of cellsI, j, it is assumed that itself and the M in setI, jThere is CA associations between -1 cell
Make all available in addition to the value that M-RNTI, P-RNTI, SI-RNTI and RA-RNTI take in relation, and this cell
The collection that RNTI values are constituted is combined into RNTT_SetI, j.Determine set of cells Cell_SetiIn all cells Mi,jMaximum Mi, and
Determine the RNTI_Set of all cells in set of cellsI, jCommon factor RNTI_Seti。
Due in CA systems, for the RNTI for needing to distribute, including C-RNTI, SPS C-RNTI, Temporary C-
RNTI, TPC-PUCCH-RNTI and TPC-PUSCH-RNTI etc., can be divided into according to the area requirement of RNTI value uniqueness as
Lower two classes：
RNTI classifications one：Only need the unduplicated RNTI of value for ensureing to distribute in the range of single subdistrict.
This kind of RNTI can include SPS C-RNTI, TPC-PUCCH-RNTI and TPC-PUSCH-RNTI.
RNTI classifications two：Need the unduplicated RNTI of value for ensureing to distribute in multiple cell ranges.
This kind of RNTI includes C-RNTI and Temporary C-RNTI.For C-RNTI, it is necessary to ensure all clothes in UE
Business cell（It is one or more）It is interior with by other UE of these cell serves C-RNTI, and allocated class in these cells
An other RNTI can not be repeated.Temporary C-RNTI may finally turn into C-RNTI, so the classification and C- of its ownership
RNTI is identical.
So, in each set of cells, it is desirable to have a RNTI set, class is provided for all cells in set of cells
Other one RNTI, now, divides to common factor progress and obtains at least two subsets, specifically include：
Common factor division is obtained into the first RNTI set and the 2nd RNTI set；
When the number of cells in set of cells is more than one, the 2nd RNTI is gathered to the sub- RNTI for being divided into setting quantity
Set.
Now, the RNTI of classification one is distributed for all cells in set of cells from the first RNTI set, from second
The RNTI of classification two is distributed in RNTI set or each sub- RNTI set for each cell in set of cells.It is every in set of cells
Individual cell can use all RNTI values in the first RNTI set, and the use of each cell is separate（I.e. first
RNTI is integrated into each cell and is multiplexed completely, and distribution of the cell of some in set of cells on some RNTI value does not influence other small
Distribution of the area to this RNTI value）.
Specifically, in RNTI_SetiThe first RNTI set RNTI_Type1_Subset of middle divisioniFor distributing classification one
RNTI, the set that remaining RNTI values are constituted is divided into OiIndividual subset, generally, OiNeed to be more than or equal in set of cells
The maximum that there is the quantity of the cell of cooperation relation with same cell plus one, i.e. Oi≥Mi, so that ensure any cell and with this
There is the corresponding different subset of each cell of cooperation relation in cell.Arbitrary cells Cell in this set of cellsI, jIn, use
Same subsets RNTI_Type1_SubsetiTo distribute the RNTI of classification one, the O is usediSome subset RNTI_ that height is concentrated
Type2_Subseti,kRNTI for distributing classification two.
In such scheme, the RNTI of classification one of all cells distribution all uses identical value set in set of cells
（That is the first RNTI set RNTI_Type1_Subseti）, and the identical value is integrated into each cell independently
Multiplexing completely, therefore RNTI in this RNTI value set has obtained sufficient multiplexing in different districts, service efficiency compared with
It is high.RNTI_SetiIn RNTI values be usually continuous, or for the convenience of operation, only take RNTI occur simultaneously in RNTI
Continuous part constitutes RNTI_Seti.Dividing the RNTI subsets of classification two（That is RNTI_Type2_SubsetI, k）When, it is believed that it can draw
RNTI values in the set that the RNTI values divided are constituted are also continuous.All cells after division in set of cells it is available
The intersection of sets collection of RNTI values is as shown in Figure 2.
Further, the embodiment of the present invention provides the son that the 2nd RNTI set is divided into setting quantity by two kinds of concrete modes
RNTI gathers：
The RNTI values included in the every sub- RNTI set obtained after mode one, division are continuous.Each sub- RNTI set
In the RNTI numbers that include can be with equal, can also be based on the corresponding cell of each sub- RNTI set（It is assigned with this sub- RNTI
One or more cells of set）Actual RNTI demands adjust the RNTI numbers included in this sub- RNTI set.Sub- RNTI collection
Conjunction can be represented with first with the two parameters of RNTI numbers included in RNTI and subset.
Mode two, n-th of the RNTI that can be divided in RNTI set be included into sub- RNTI set n, and RNTI can be divided
Difference in set between n-th of RNTI is OiIntegral multiple（>=1）All RNTI be all included into sub- RNTI set n.Now
The RNTI values included in certain sub- RNTI set are distributed on number axis in pectination at equal intervals, and each sub- RNTI set is included
RNTI numbers it is of substantially equal.Sub- RNTI set can use first available RNTI, OiAnd the RNTI numbers included in subset this
Three parameters are represented.
Mode one more flexibly, the RNTI numbers actually included in each sub- RNTI set can be adjusted as needed.Side
Formula two is more directly perceived, it can be seen directly that the RNTI scopes that each sub- RNTI set is included are non-overlapping copies, but this side
Case can not adjust the RNTI numbers included in each sub- RNTI set as needed.
Now, the 2nd RNTI is gathered to the sub- RNTI set for being divided into setting quantity, specifically included：
According to putting in order for RNTI, the sub- RNTI that the RNTI during the 2nd RNTI is gathered is divided into setting quantity gathers,
Now, the RNTI quantity in every sub- RNTI set can be different；Or
The remainder identical RNTI of arrangement sequence number divided by sub- RNTI collective numbers, is divided into one during 2nd RNTI is gathered
In sub- RNTI set, now, the RNTI quantity variances in every sub- RNTI set are not more than 1.Wherein, those skilled in the art can
With the arranged mode for the arrangement sequence number for flexibly setting RNTI, for example, can be from 1 open numbering, can also be from 0 open numbering.
It is determined that, it is necessary to which the first RNTI is gathered after the division of each sub- RNTI set（That is RNTI_Type1_
Subseit）With each sub- RNTI set（That is RNTI_Type2_Subseti,k）Distribute to set of cells Cell_SetiIn each
Cell CellI, j。
When carrying out RNTI distribution, in step S102, according to RNTI types, from the current area pair belonging to user equipment
Answer and distribute RNTI in RNTI corresponding with RNTI types set for user equipment, specifically include：
When RNTI types only to need to ensure the RNTI of not duplicate allocation, i.e. RNTI classifications one in the range of single subdistrict,
Then the RNTI not used by the user equipment of this cell is distributed from the first RNTI set for user equipment；
When RNTI types to need to ensure the RNTI of not duplicate allocation, i.e. RNTI classifications two in multiple cell ranges, then
From the corresponding sub- RNTI set in current area RNTI is distributed for user equipment.
The mode gathered according to the corresponding sub- RNTI of different determinations each cell, in the sub- RNTI set of setting quantity,
The maximum that the setting quantity is more than or equal in set of cells the quantity for the cell that there is cooperation relation with same cell plus one
.It is preferred that the sub- RNTI set of setting quantity can be specially：
The quantity sub- RNTI set equal with the number of cells in set of cells；Or
Plus one equal with there is the maximum of the quantity of the cell of cooperation relation in set of cells with same cell for quantity
Sub- RNTI set.
Correspondingly, the embodiment of the present invention provides two kinds of modes for preferably determining the corresponding sub- RNTI set of each cell：
Mode one, as shown in Figure 3 a, when the sub- RNTI collection of setting quantity is combined into quantity and the number of cells in set of cells
When equal sub- RNTI gathers, each cell in set of cells corresponds to different sub- RNTI set；
OiValue be Ni, now each sub- RNTI set can be distributed into set of cells Cell_Set successivelyiIt is middle different
Cell CellI, j, different districts distribute the RNTI of classification two using different sub- RNTI set.
Mode two, as shown in Figure 3 b, when the sub- RNTI collection of setting quantity be combined into quantity with set of cells and same cell
When there is the maximum sub- RNTI that the plus one equal set of the quantity of the cell of cooperation relation, any cell and exist with the cell
The sub- RNTI that each cell correspondence of cooperation relation is different gathers；
OiValue be Mi, now need for set of cells Cell_SetiIn each cell CellI, jDistribution difference or phase
With sub- RNTI set, but must assure that any two in set of cells has the cell distribution of CA cooperation relations each other
Sub- RNTI set is different.Which is more complicated than mode one, but because MiAlways it is less than or equal to Ni, divide in this way
Sub- RNTI number of sets is generally less, and available RNTI numbers may be more in every sub- RNTI set, are more beneficial for limited
RNTI efficient utilization.
A kind of possible sub- RNTI set assigning process is described as follows：
Take set of cells Cell_SetiIn any one unallocated sub- RNTI set cell CellI, j, it is assumed that deposited with it
In all cells of CA cooperation relations, the set of cells for having distributed sub- RNTI set is Allocated_CellsI, j, divided
The sub- RNTI collection matched somebody with somebody is combined into Allocated_RNTI_SubsetsI, j, the set of cells for not yet distributing sub- RNTI set is
Pending_CellsI, j, then it is followed successively by cell CellI, jAnd Pending_CellsI, jIn each cell distribution remove
Allocated_RNTI_SubsetsI, jOutside each sub- RNTI set, it is ensured that the sub- RNTI set of each cell distribution is each not
It is identical, sub- RNTI set is carried out to each cell and is distributed, until set of cells Cell_SetiIn all cells be all assigned with son
Untill RNTI gathers.
After sub- RNTI set is distributed, in addition it is also necessary to by the first RNTI set RNTI_Type1_SubsetiDistribute to small
Area's set Cell_SetiIn each cell CellI, jFor distributing the RNTI of classification one.
RNTI is distributed and reclaimed as needed during distribution RNTI, it is necessary in each cell.
Each RNTI set RNTI_Type1_Subset of cell maintenance the firstiWith the sub- RNTI set RNTI_ of distribution
Type2_Subseti,kInterior RNTI distribution conditions.When cell needs the RNTI of one classification one of distribution, from the first RNTI collection
Close RNTI_Type1_SubsetiIt is middle to search the RNTI not distributed in the cell, the RNTI found is distributed, afterwards by this RNTI
Labeled as having distributed；When cell needs the RNTI of one classification one of release, in subset RNTI_Type1_SubsetiIt is middle by this
RNTI is labeled as unallocated.When cell needs the RNTI of one classification two of distribution, searched not from the sub- RNTI set of distribution
The RNTI of distribution, distributes the RNTI found, is labeled as this RNTI having distributed afterwards；When cell needs one classification two of release
During RNTI, by this RNTI labeled as unallocated in sub- RNTI set.
RNTI cell always UE PCell is distributed for UE, or is likely to become UE PCell（For example in handoff procedure
In, distribute C-RNTI by Target cell）.When PCell be UE configure some SCell when, be UE distribution C-RNTI in this SCell
Inside also effectively, now SCell and C-RNTI need not explicitly be distributed for this UE.Using above-mentioned RNTI allocation flows, then it can protect
Demonstrate,prove the RNTI distributed for UE and will not be produced in the SCell of UE subsequent configurations with other allocated RNTI in cell and conflicted, and
And ensure the efficient utilization of limited RNTI resources as far as possible.Conflict herein, which refers to, is used for the RNTI of different identification purpose in single subdistrict
Value is identical, causes mark to be obscured, actually can not the different target of unique mark.
RNTI distribution methods provided in an embodiment of the present invention are illustrated with a specific embodiment below：
For two service frequencies under some sector of some base station, one logic district of each service frequency correspondence is false
It is set to cell A and cell B.Assuming that the two cell configurations are the presence of CA cooperation relations each other by OAM, and the two are small
CA cooperation relations are not present between other cells in arbitrary cells and network in area, then the two cells may be constructed one
Individual set of cells Cell_Seti, NiValue is 2, MiValue is 2, OiValue is 2.Assuming that the RNTI_Set of this set of cellsiFor
[003D, FFF3], altogether comprising 65463 RNTI values, wherein [X, Y] represents all hexadecimal integers from X to Y, X and
Y is represented with hexadecimal.
First RNTI set RNTI_Type1_SubsetiIt assume that as [003D, 5579], taken comprising 21821 RNTI
Value.The subset for distributing the RNTI of classification two is evenly dividing according to sub- RNTI set dividing mode one, then sub- RNTI set RNTI_
Type2_SubsetI, 1For [557A, AAB6], sub- RNTI set RNTI_Type2_SubsetI, 2For [AAB7, FFF3], wrap respectively
Containing 21821 RNTI values.
Because NiAnd MiValue is identical, so the output knot of two kinds of modes for determining the corresponding sub- RNTI set of each cell
It is really identical.Can be now cell A distribution set RNTI_Type1_SubsetiFor the RNTI of subsequent allocations classification one, distribution
Collect RNTI_Type2_Subseti,1For the RNTI of subsequent allocations classification two；For cell B distribution set RNTI_Type1_Subseti
For the RNTI of subsequent allocations classification one, distribution subset RNTI_Type2_SubsetI, 2For the RNTI of subsequent allocations classification two.
