Illustrated with reference to specific example, reference picture 2, be under base station provided in an embodiment of the present invention
Subdistrict position relation schematic diagram.There are 3 base stations, respectively base station 1, base station 2 and base station 3 in Fig. 2,
Wherein there are the cell cell0, the cell cell1 and a F frequency of a F-band of a D frequency range under base station 1
The cell cell2 of section, there is a F-band cell cell3 under base station 2, have a D frequency range small under base station 3
An area cell4 and F-band cell5.The D frequency ranges cell0 and F-band cell1 in base station 1 in base station 1
It is overlapping covered be region 1, the D frequency ranges cell0 in the base station 1 and F-band cell2 in base station 1
It is overlapping covered be region 2, the D frequency ranges cell0 in the base station 1 and F-band cell3 in base station 2
It is overlapping covered be region 3, the D frequency ranges cell4 in the base station 3 and F-band cell5 in base station 3
It is overlapping covered be region 4.
Assuming that the frequency that 6 cells use respectively is：Cell0 (d0 frequencies), cell1 (f1 frequencies), cell2
(f2 frequencies), cell3 (f3 frequencies), cell4 (d4 frequencies), cell5 (f5 frequencies).
Overlapping covered due to cobasis station difference alien-frequency district can enter CA, therefore for above-mentioned 4
Individual region, specifically have as defined below：
Region 1 in figure：Cell0's and cell1 is overlapping covered in same base station, can enter CA；
Region 2：Cell0's and cell2 is overlapping covered in same base station, can enter CA；
Region 3：Cell0's and cell3 is overlapping covered under different base station, and existing network construction mode wouldn't prop up
CA is held, therefore CA cannot be entered；
Region 4：Cell4's and cell5 is overlapping covered in same base station, can enter CA.
Assuming that when carrying out drive test, bus vehicle has two two test equipment terminals 1 and terminal 2, uses respectively
In locking D frequency ranges and F-band, when drive test vehicle is travelled along in Fig. 2, successively by A, B,
C, this 8 sampled point of D, E, F, G, H (certainly, sampling number is not only 8 in practical application,
According to being actually needed, typically have hundreds and thousands of), below come to illustrate be how to obtain in the present invention
Using to CA frequencies collection (when initial CA frequencies collection for sky)：
When drive test vehicle reaches sampled point A, under base station 1, due to cell signal can not be detected,
Therefore the CA collection of base station 1 is still sky；
When drive test vehicle reaches sampled point B, due to being only able to detect a cell, i.e. cell1 cell
Signal, therefore judge that CA states cannot be entered herein, the CA collection of base station 1 is still sky；
When drive test vehicle reaches sampled point C, due to two cells, i.e. cell0 can be detected simultaneously
With cell1 cell signal, and, it is assumed that the RSRP for the D frequency ranges cell0 that terminal 1 detects be more than electricity
Jib door limit value, and the F-band cell1 RSRP that terminal 2 detects then sentences also greater than level threshold value
It is fixed to enter CA herein, thus respectively by corresponding to frequency d0 corresponding to cell cell0 and cell cell1
Frequency f1 is added to CA frequencies concentration, and now the CA frequencies collection of base station 1 is { d0, f1 }；
When drive test vehicle reaches sampled point D, although the signal of two cells can be detected simultaneously by, by
Then the cell under different base station, therefore CA cannot be entered herein, now the CA frequency collection of base station 1
Still it is { d0, f1 }；
When drive test vehicle reaches sampled point E, due to two cells, i.e. cell0 can be detected simultaneously
With cell2 cell signal, and, it is assumed that the RSRP for the D frequency ranges cell0 that terminal 1 detects be more than electricity
Jib door limit value, and the F-band cell2 RSRP that terminal 2 detects then sentences also greater than level threshold value
It is fixed to enter CA herein, thus respectively by corresponding to frequency d0 corresponding to cell cell0 and cell cell2
Frequency f2 is added to CA frequencies concentration, and being concentrated due to CA frequencies has had frequency d0, therefore only needs
F2 is added to CA frequency collection, now the CA frequencies collection of base station 1 is { d0, f1, f2 }；
When drive test vehicle reaches sampled point F, due to being only able to detect a cell, i.e. cell2 cell
Signal, therefore judge to enter CA states herein, the CA frequencies collection of base station 1 be still d0, f1,
f2}；
When drive test vehicle reaches sampled point G, due to two cells, i.e. cell4 can be detected simultaneously
With cell5 cell signal, and, it is assumed that the RSRP for the D frequency ranges cell4 that terminal 1 detects be more than electricity
Jib door limit value, and the F-band cell5 RSRP that terminal 2 detects then sentences also greater than level threshold value
It is fixed to enter CA herein, but due to being under base station 3, it is therefore desirable to re-establish a base station
3 CA frequency collection, original state is sky, then respectively by frequency d4 and cell corresponding to cell cell4
The CA frequencies that frequency f5 corresponding to cell5 is added to base station 3 are concentrated, and now the CA frequency collection of base station 3 is
{ d4, f5 }；
When drive test vehicle reaches sampled point H, due to being only able to detect a cell, i.e. cell5 cell
Signal, therefore judge that CA states cannot be entered herein, the CA frequencies collection of base station 3 is still { d4, f5 }.
By way of above-mentioned drive test, for each base station, a CA frequency collection can be obtained, in reality
In, in fact, a base station is directed to, generally, can be corresponding by each cell under base station
Frequency be all added to CA frequencies concentration.
For a base station, after the frequency collection of the base station is obtained, can be done based on the frequency set pair terminal
CA configure, for example, if the CA frequencies collection of a base station for d0, d1, d2, d3, f4, f5,
F6, f7 }, then the terminal k under this base station, it is assumed that the Pcell that terminal k is currently located is frequency d0 corresponding
Cell, if terminal k meets carrier aggregation condition, i.e. terminal k has CA abilities, then CA frequencies
The frequency d1, d2, d3 of concentration, f0, f1, cell corresponding to f2, f3 difference, can serve as in theory
Terminal k Scell.
Based on explanation above, it is assumed that have 8 cells, and each cell and corresponding frequency under a base station
Respectively：Cell0 (d0), cell1 (d1), cell2 (d2), cell3 (d3), cell4 (f4), cell5 (f5),
Cell6 (f6), cell7 (f7).How be described below is a terminal distribution Pcell with CA abilities.
In above-mentioned steps 101, base station is when it is determined that terminal meets carrier aggregation condition, from the base station
CA frequencies, which are concentrated, determines candidate's SCC frequencies, it is assumed that the Pcell of terminal 1 is cell0, then terminal 1 Scell
It can be selected from cell1~cell7.
Candidate's SCC frequencies are determined first, specifically, it is determined that the mode of candidate's SCC frequencies of terminal has very
It is a variety of, such as can be by frequency of the CA frequencies concentration in addition to frequency corresponding to the Pcell where terminal all
Candidate's SCC frequencies are determined as candidate SCC frequencies or according to frequency type, such as first will
All frequencies in D frequency ranges are defined as candidate's SCC frequencies, if cell is not corresponding to these frequencies
Pcell can be used as, then all frequencies of F-band are defined as candidate's SCC frequencies again.
Alternatively, in the embodiment of the present invention, the mode of another determination candidate's SCC frequencies is provided：Base
Stand and the priority of each frequency is concentrated according to CA frequencies, the frequency of limit priority is determined from the CA frequencies collection
Point is the candidate SCC frequencies, in the candidate SCC frequencies corresponding to the Pcell not comprising the terminal
Frequency；The frequency of the limit priority includes one or more SCC frequencies.
For example, if under base station, cell is stronger in the signal of D frequency ranges, then can be by D frequency ranges
All cells be divided into high priority cell, accordingly, the frequency of D frequency ranges is then high priority frequency,
Therefore the d0, d1, d2 under base station, d3 are then divided into the first priority frequency, and f4, f5, f6, f7 are then drawn
It is divided into the second priority frequency, and the first priority is higher than the second priority.
Therefore, because the Pcell of terminal 1 is cell0, corresponding frequency d0, therefore in the method, it is determined that
Candidate SCC frequencies be d1, d2 and d3.
In above-mentioned steps 102, base station issues A4 measurements control signaling according to the candidate SCC frequencies and arrived
The terminal.
In above-mentioned steps 103, A4 measurement reports that base station receiving terminal reports, and according to the A4
Measurement report, the candidate Scell of the terminal is determined, can specifically be included：The frequency of the limit priority
When having multiple, A4 measurement reports that the base station reports according to the terminal, the candidate SCC frequencies are determined
The RSRP of cell corresponding to point, and the order according to RSRP from high to low, successively by candidate's SCC frequencies
Candidate Scell of the corresponding cell as the terminal.
For example, in upper example, because the candidate's SCC frequencies for being handed down to terminal 1 have d1, d2 and d3, often
Individual frequency corresponds to cell1, cell2 and cell3 respectively, and then terminal 1 measures the RSRP of this 3 cells respectively,
And it is carried in A4 measurement reports and reports base station, after base station receives A4 measurement reports, according to it
In each candidate SCC frequencies respectively corresponding to cell RSRP, by wherein RSRP values maximum cell
As candidate Scell, such as according to RSRP values from high to low, corresponding cell is followed successively by cell3, cell2,
Cell1, then using cell3 as candidate cell.
In above-mentioned steps 104, base station attempts to establish the Pcell and the candidate Scell of terminal connection,
If connection is successfully established, it is determined that the candidate Scell is the Scell of the terminal.
For example, above-mentioned candidate cell is cell3, base station attempt to establish the Pcell (i.e. cell0) of terminal 1 and
Connection between candidate cell (i.e. cell3), if be successfully established, it is determined that cell3 is the Scell of terminal 1.
Alternatively, if the Pcell and the candidate Scell of the terminal connection are established in the base station not successfully,
The candidate SCC frequencies then are deleted from the CA frequencies collection, returns from the CA frequencies collection and determines highest
The step of frequency of priority is the candidate SCC frequencies.
For example, base station attempts to establish the Pcell (i.e. cell0) of terminal 1 and candidate cell (i.e. cell3)
Between connection, if establishing connection failure, base station is using cell2 as candidate Pcell, i.e., by candidate SCC
The frequency cell that RSRP value rankings are taken second place in corresponding cell respectively continues to attempt to establish as candidate Pcell
Connection between the Pcell (i.e. cell0) and candidate cell (i.e. cell2) of terminal 1, if establishing connection
Success, it is determined that cell2 is the Scell of terminal 1.
If establishing the connection between the Pcell (i.e. cell0) of terminal 1 and candidate cell (i.e. cell2),
Still fail, then using cell1 as candidate Pcell, continue to attempt to establish the Pcell (i.e. cell0) of terminal 1
With the connection between candidate cell (i.e. cell1), if establishing successful connection, it is determined that cell1 is terminal
1 Scell.
If establishing the connection between the Pcell (i.e. cell0) of terminal 1 and candidate cell (i.e. cell1),
Still fail, now cell corresponding to candidate SCC frequencies was all attempted, and was not still found
One can be successfully established the cell being connected with the Pcell of terminal 1.
Now, base station using all frequencies in the second priority as candidate SCC frequencies (i.e. frequency f4, f5,
F6, f7), then issue A4 and measure control signaling to terminal 1, then using mode same as described above, root
The RSRP values of cell corresponding to each frequency in the A4 measurement reports reported according to terminal, from high to low suitable
Sequence, candidate cell is determined successively, and attempt to establish the connection between the Pcell and candidate cell of terminal 1,
Assuming that the cell4 that terminal 1 measures, cell5, cell6, cell7 respectively corresponding to RSRP from high to low successively
Respective cell is：Cell5, cell6, cell4, cell7, then base station is according to cell5, cell6, cell4, cell7
Order, the connection established between the Pcell and candidate cell of terminal 1 is attempted successively, as long as having one small
Area establishes successful connection, it is determined that and it is the Scell of terminal 1, if all cells all establish connection failure,
It is determined that can not be that terminal 1 distributes Pcell, i.e. CA failures.
Further, since it is directed to F+D scenes, it is understood that there may be the situation of different-frequency measure, as shown in Fig. 2
It is overlapping covered between the cell0 of D frequency ranges and the cell1 of F-band for region 1, if eventually
End is at region 1, using D frequency ranges as main carrier, and using F-band as secondary carrier, then due to D frequencies
Section and F-band belong to different frequency ranges, therefore need to configure measurement Gap during occupancy D frequency ranges, could carry out
Different-frequency measure F-band cell, it otherwise can not be directed to F-band cell and carry out different-frequency measure, therefore, alternatively,
The base station issues A4 according to the candidate SCC frequencies and measures control signaling to before the terminal, also wraps
Include：The base station determines that candidate SCC frequencies frequency corresponding with the Pcell cells of the terminal is different
Frequency range frequency and QCI (Quality of Service Class Identifier, service quality is not present in the terminal
Grade indicate) equal to 1 carrying after, be the terminal allocating and measuring gap Gap (measurement gap).
