Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a terminal carrier aggregation configuration method and a base station.
Background
The Time Division Long Term Evolution (TD-LTE) network has already realized commercial deployment of carrier aggregation technologies in frequency bands of D + D, E + E, etc., and formed a series of deployment, construction and optimization schemes of the shaped carrier aggregation technologies in frequency bands. Because the current 4G (the 4th Generation mobile communication, fourth Generation mobile communication technology) commercial terminal does not formally support the carrier aggregation technology between F + D frequency bands, the existing network has fewer sites for starting the F + D carrier aggregation, and there is no clear technical scheme for how to plan, construct and optimize the F + D carrier aggregation, and basically, the technical scheme for planning, constructing and optimizing the carrier aggregation technology in the frequency bands such as D + D is used.
The basic service flow of carrier aggregation in the existing D + D frequency band is mainly divided into four steps, as shown in fig. 1, specifically as follows:
1) the OSS (The Office of statistical Services, operation support system) configures a CA (Carrier Aggregation) cell set for each cell at a base station according to a coverage relationship between cells, and configures parameters related to CA characteristics. CA cell set refers to the configuration of several cells into a logical set at a base station, and only the cells in the set are allowed to aggregate.
2) CA UE (User Equipment) establishes initial connection in PCell (Primary Cell).
3) The base station issues A4 measurement including CA cell set information, and configures a SCell (Secondary cell) of the CA UE according to a measurement result reported by the CA UE; the SCell is configured to a secondary cell of the CA UE through an RRC (Radio Resource Control) connection reconfiguration message on the PCell, and may provide more Radio resources for the CA UE.
4) And monitoring the data volume of the CA UE in real time, and activating or deactivating the SCell according to the result.
The problems of the method are as follows: based on the CA cell set configuration principle, each CA set allows 6 cells to be configured at maximum, and if the co-sited number exceeds 6 cells, all the cells cannot be configured to the same cell set, and the configuration is complex. For example, in the existing network, 200 stations need to configure the CA function, and then a plurality of CA cell sets need to be configured for each station, cells in each cell set are different, and 1 person needs at least 2 days to complete CA configuration.
In summary, the conventional carrier aggregation technology has the technical problems of complex configuration and low configuration efficiency.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, a method for configuring carrier aggregation for a terminal according to an embodiment of the present invention includes:
step 101, when a base station determines that a terminal meets a Carrier aggregation condition, determining candidate SCC (Secondary Component Carrier) frequency points from a Carrier aggregation CA frequency point set of the base station, wherein the CA frequency point set at least comprises two different frequency points which are detected at the same position in a coverage area of the base station and meet a signal quality index;

In the embodiment of the invention, a CA frequency point set is configured under one base station, and the CA frequency point set is obtained according to the following modes: in the embodiment of the invention, an F frequency band is taken as an example for explanation, two test terminals are selected to occupy sampling points of the same base station at the same time for evaluation, and if two different frequency points are detected at the same position in the coverage area of the base station at the same time by the two test terminals and the RSRP (Reference Signal Receiving Power) of the cells corresponding to the two different frequency points is not less than a level threshold value, the two different frequency points are added into the CA frequency point set.
Reference is made to fig. 2, which is a schematic diagram illustrating a location relationship between cells under a base station according to an embodiment of the present invention. In fig. 2, there are 3 base stations, which are a base station 1, a base station 2 and a base station 3, where there are a cell0 of a D-band, a cell1 of an F-band and a cell2 of an F-band under the base station 1, a cell3 of an F-band under the base station 2, and a cell4 of a D-band and a cell5 of an F-band under the base station 3. An overlapping coverage area of the D-band cell0 in the base station 1 and the F-band cell1 in the base station 1 is area 1, an overlapping coverage area of the D-band cell0 in the base station 1 and the F-band cell2 in the base station 1 is area 2, an overlapping coverage area of the D-band cell0 in the base station 1 and the F-band cell3 in the base station 2 is area 3, and an overlapping coverage area of the D-band cell4 in the base station 3 and the F-band cell5 in the base station 3 is area 4.
Suppose that the frequency points used by 6 cells are: cell0 (d 0 frequency point), cell1 (f 1 frequency point), cell2 (f 2 frequency point), cell3 (f 3 frequency point), cell4 (d 4 frequency point), and cell5 (f 5 frequency point).
Since the overlapping coverage areas of different inter-frequency cells of the common base station may enter CA, the above 4 areas are specifically defined as follows:
region 1 in the figure: the overlapping coverage areas of cell0 and cell1 in the same base station can enter CA;
region 2: the overlapping coverage areas of cell0 and cell2 in the same base station can enter CA;
region 3: in the overlapping coverage areas of cell0 and cell3 under different base stations, the existing network construction mode does not support CA temporarily, so that the existing network construction mode cannot enter CA;
region 4: the overlapping coverage areas of cell4 and cell5 in the same base station may enter CA.
Assuming that a drive test vehicle has two test device terminals 1 and 2 for locking a D frequency band and an F frequency band, respectively, when the drive test vehicle travels along fig. 2, the drive test vehicle sequentially passes through A, B, C, D, E, F, G, H sampling points of 8 (of course, the number of sampling points in practical application is not less than 8, and generally there are hundreds or thousands of sampling points according to practical needs), and how to obtain a CA frequency point set used in the present invention (the CA frequency point set is empty at the beginning) is specifically described below:
when the drive test vehicle reaches the sampling point A and is positioned under the base station 1, the CA set of the base station 1 is still empty because the cell signal cannot be detected;
when the road test vehicle reaches the sampling point B, because only one cell, namely the cell signal of the cell1, can be detected, the CA state can not be entered, and the CA set of the base station 1 is still empty;
when a drive test vehicle reaches a sampling point C, cell signals of two cells, namely cell0 and cell1, can be detected at the same time, and it is assumed that RSRP of a D-band cell0 detected by a terminal 1 is greater than a level threshold value and RSRP of an F-band cell1 detected by a terminal 2 is also greater than the level threshold value, it is determined that CA can enter the cell, so that a frequency point D0 corresponding to the cell0 and a frequency point F1 corresponding to the cell1 are added to a CA frequency point set, and at this time, the CA frequency point set of the base station 1 is { D0, F1 };
when a road test vehicle reaches a sampling point D, although signals of two cells can be detected at the same time, the cells under different base stations cannot enter CA, and the CA frequency point set of the base station 1 is still { D0, f1 };
when a road test vehicle reaches a sampling point E, two cells, namely cell signals of cell0 and cell2, can be detected at the same time, and it is assumed that RSRP of a D-band cell0 detected by a terminal 1 is greater than a level threshold value and RSRP of an F-band cell2 detected by a terminal 2 is also greater than the level threshold value, it is determined that CA can enter the cell, so that a frequency point D0 corresponding to the cell0 and a frequency point F2 corresponding to the cell2 are added to a CA frequency point set respectively, and since the CA frequency point set already has the frequency point D0, only F2 needs to be added to the CA frequency point set, and at the moment, the CA frequency point set of the base station 1 is { D0, F1, F2 };
when the road test vehicle reaches the sampling point F, only one cell, namely the cell signal of the cell2, can be detected, so that the CA state cannot be entered, and the CA frequency point set of the base station 1 is still { d0, F1, F2 };
when a road test vehicle reaches a sampling point G, two cells, namely cell signals of cell4 and cell5, can be detected at the same time, and it is assumed that RSRP of a D-band cell4 detected by a terminal 1 is greater than a level threshold value, and RSRP of an F-band cell5 detected by a terminal 2 is also greater than the level threshold value, it is determined that CA can enter the cell, but since the terminal is under a base station 3, a CA frequency point set of the base station 3 needs to be re-established, the initial state is null, then a frequency point D4 corresponding to the cell4 and a frequency point F5 corresponding to the cell5 are added into the CA frequency point set of the base station 3, and at this time, the CA frequency point set of the base station 3 is { D4, F5 };
when the road test vehicle reaches the sampling point H, since only one cell, namely the cell signal of the cell5, can be detected, it is determined that the CA state cannot be entered here, and the CA frequency point set of the base station 3 is still { d4, f5 }.
By means of the drive test, a CA frequency point set can be obtained for each base station, and in practical application, in fact, for one base station, in general, the frequency point corresponding to each cell under the base station can be added into the CA frequency point set.
For a base station, after obtaining a frequency point set of the base station, CA configuration may be performed on a terminal based on the frequency point set, for example, if the CA frequency point set of a base station is { d0, d1, d2, d3, f4, f5, f6, f7 }, then a Pcell of the terminal k in the base station is assumed to be a cell corresponding to a frequency point d0, and if the terminal k meets a carrier aggregation condition, that is, the terminal k has CA capability, cells corresponding to frequency points d1, d2, d3, f4, f5, f6, and f7 in the CA frequency point set may all be used as an Scell of the terminal k in theory.
Based on the above description, assume that there are 8 cells under a base station, and each cell and corresponding frequency point are: cell0 (d 0), cell1 (d 1), cell2 (d 2), cell3 (d 3), cell4 (f 4), cell5 (f 5), cell6 (f 6), and cell7 (f 7). How to allocate Scell to a terminal with CA capability is described below.
In step 101, when the base station determines that the terminal meets the carrier aggregation condition, candidate SCC frequency points are determined from the CA frequency point set of the base station, and assuming that the Pcell of the terminal 1 is cell0, the Scell of the terminal 1 may be selected from cells 1 to 7.
Firstly, determining candidate SCC frequency points, specifically, there are many ways to determine candidate SCC frequency points of a terminal, for example, all frequency points in a CA frequency point set except a frequency point corresponding to a Pcell where the terminal is located may be used as the candidate SCC frequency points, or the candidate SCC frequency points may be determined according to frequency point types, for example, all frequency points in a D frequency band are determined as the candidate SCC frequency points first, and if cells corresponding to the frequency points cannot be used as scells, all frequency points in an F frequency band are determined as the candidate SCC frequency points.
Optionally, in the embodiment of the present invention, another way of determining candidate SCC frequency points is provided: the base station determines the frequency point with the highest priority from the CA frequency point set as the candidate SCC frequency point according to the priority of each frequency point in the CA frequency point set, wherein the candidate SCC frequency point does not contain the frequency point corresponding to the Pcell of the terminal; the frequency points with the highest priority comprise one or more SCC frequency points.
For example, if the cells in the D band are stronger under the base station, all cells in the D band may be divided into high priority cells, and accordingly, the frequency points in the D band are high priority frequency points, so that D0, D1, D2, D3 under the base station are divided into first priority frequency points, f4, f5, f6, f7 under the base station are divided into second priority frequency points, and the first priority is higher than the second priority.
Therefore, since the Pcell of the terminal 1 is cell0 and corresponds to the frequency point d0, in the method, the determined candidate SCC frequency points are d1, d2 and d 3.
In the step 102, the base station issues an a4 measurement control signaling to the terminal according to the candidate SCC frequency point.
In step 103, the receiving, by the base station, the a4 measurement report reported by the terminal, and determining the candidate Scell of the terminal according to the a4 measurement report may specifically include: when the frequency points with the highest priority are multiple, the base station determines the RSRP of the cells corresponding to the candidate SCC frequency points according to an A4 measurement report reported by the terminal, and sequentially takes the cells corresponding to the candidate SCC frequency points as the candidate Scell of the terminal according to the sequence of the RSRP from high to low.
For example, in the above example, since the candidate SCC frequency points issued to the terminal 1 have d1, d2, and d3, each frequency point corresponds to a cell1, a cell2, and a cell3, then the terminal 1 measures RSRPs of the 3 cells respectively, and reports the RSRPs carried in an a4 measurement report to the base station, after receiving the a4 measurement report, the base station takes the cell with the largest RSRP value as a candidate Scell according to the RSRPs of the cells corresponding to the candidate SCC frequency points respectively, for example, the corresponding cells are cell3, cell2, and cell1 in sequence according to the RSRP value from high to low, and then takes the cell3 as the candidate cell.
In step 104, the base station tries to establish a connection between the Pcell of the terminal and the candidate Scell, and if the connection is successfully established, it is determined that the candidate Scell is the Scell of the terminal.
For example, the candidate cell is cell3, the base station attempts to establish a connection between the Pcell (i.e., cell 0) of terminal 1 and the candidate cell (i.e., cell 3), and if the establishment is successful, it is determined that cell3 is the Scell of terminal 1.
Optionally, if the base station does not successfully establish the connection between the Pcell of the terminal and the candidate Scell, deleting the candidate SCC frequency point from the CA frequency point set, and returning to the step of determining the frequency point with the highest priority from the CA frequency point set as the candidate SCC frequency point.
For example, the base station attempts to establish a connection between the Pcell (i.e., cell 0) of the terminal 1 and the candidate cell (i.e., cell 3), if the connection establishment fails, the base station uses the cell2 as the candidate Scell, that is, the cell with the next ranked RSRP value in the cells corresponding to the candidate SCC frequency points respectively is used as the candidate Scell, continues to attempt to establish a connection between the Pcell (i.e., cell 0) of the terminal 1 and the candidate cell (i.e., cell 2), and if the connection establishment succeeds, determines that the cell2 is the Scell of the terminal 1.
If the connection between the Pcell (i.e., cell 0) of the terminal 1 and the candidate cell (i.e., cell 2) is still failed to be established, the cell1 is taken as a candidate Scell, the connection between the Pcell (i.e., cell 0) of the terminal 1 and the candidate cell (i.e., cell 1) is continuously attempted to be established, and if the connection is successfully established, the cell1 is determined to be the Scell of the terminal 1.
If the connection between the Pcell (i.e., cell 0) of the terminal 1 and the candidate cell (i.e., cell 1) is still failed, at this time, all cells corresponding to the candidate SCC frequency point have been tried, and a cell which can successfully establish a connection with the Pcell of the terminal 1 is still not found.
At this time, the base station takes all frequency points in the second priority as candidate SCC frequency points (i.e., frequency points f4, f5, f6, and f 7), then issues an a4 measurement control signaling to the terminal 1, and then determines candidate cells in sequence from high to low according to RSRP values of cells corresponding to the frequency points in an a4 measurement report reported by the terminal in the same manner as described above, and tries to establish connection between the Pcell of the terminal 1 and the candidate cells, assuming that RSRP values corresponding to cells measured by the terminal 1, cell4, cell5, cell6, and cell7 respectively correspond to the cells in sequence from high to low: cell5, cell6, cell4, and cell7, the base station sequentially tries to establish a connection between the Pcell of the terminal 1 and the candidate cell according to the sequence of cell5, cell6, cell4, and cell7, and determines that the Pcell of the terminal 1 is Scell as long as one cell is successfully established, and determines that Scell cannot be allocated to the terminal 1 if all cells are unsuccessfully established, that is, CA fails.
In addition, as for an F + D scenario, there may be a case of inter-frequency measurement, as shown in fig. 2, for area 1, the overlapping coverage area between cell0 of the D band and cell1 of the F band, if the terminal is in area 1, the D band is used as a main carrier, and the F band is used as an auxiliary carrier, then since the D band and the F band belong to different bands, when occupying the D band, a measurement Gap needs to be configured to perform inter-frequency measurement on the F band cell, otherwise, inter-frequency measurement cannot be performed on the F band cell, and therefore, optionally, before issuing an a4 measurement control signaling to the terminal according to the candidate SCC frequency point, the method further includes: and after the base station determines that the candidate SCC frequency point and the frequency point corresponding to the Pcell cell of the terminal are pilot frequency band frequency points and the terminal does not have a load with a QCI (Quality of Service Class Identifier) equal to 1, configuring a measurement Gap (Gap) for the terminal.
When the base station determines that the candidate SCC frequency point and the frequency point corresponding to the Pcell cell of the terminal are pilot frequency segment frequency points, it is also necessary to determine that the terminal does not have a bearer with a QCI equal to 1 because: if the terminal is a bearer with QCI equal to 1, it is indicated that the current bearer is a Voice over Long Term Evolution (IMS-based Voice service), and at this time, the base station where the Pcell is located only schedules data on the secondary carrier without CA configuration, so CA configuration is not required, otherwise, if CA configuration is required for the terminal, it is determined that the terminal does not have a bearer with QCI equal to 1.
When the terminal does not have the bearer with the QCI equal to 1, the terminal indicates that the current service is non-Volte service, and the base station configures measurement Gap and issues A4 measurement control signaling (candidate SCC frequency point information, frequency offset, measurement broadband and other measurement parameters).
In addition, when a terminal CA is made, an important index for measuring the CA capability of a base station is the CA proportion, which refers to the proportion of sampling points that can enter a CA state under all sampling points (i.e. a certain specific geographic location) under the base station, and in the embodiment of the present invention, the CA proportion under the base station is obtained according to the following manner: if two different frequency points are detected by two testing terminals at the same time at the same sampling point in the coverage area of the base station, and the RSRP of the cells corresponding to the two different frequency points is not less than the level threshold value, determining the sampling point as a sampling point capable of entering a CA state; and taking the ratio of the number of sampling points which can enter a CA state under the base station to the total number of sampling points under the base station as the CA ratio.
For example, assuming that the base station has a total of 1100 sampling points, wherein the terminal can enter the CA state under 1000 sampling points, the CA ratio is: 1000/1100=90.91%, in order to improve the CA proportion under the base station, an embodiment of the present invention provides a method for improving the CA proportion, and optionally, after the base station determines that the candidate Scell is the Scell of the terminal, the method further includes: and if the base station receives an A6 event reported by the terminal, taking a first cell under the base station as the Scell of the terminal, wherein the first cell is an adjacent cell of the Pcell of the terminal, the frequency point corresponding to the first cell belongs to the CA frequency point set, and the signal quality of the first cell is superior to that of the current Scell of the terminal.
The event a6 indicates that the signal quality of the co-frequency neighboring cell of the secondary carrier is better than that of the current secondary carrier, so that when the base station receives the event a6 reported by the terminal, the base station tries to switch the Scell for the terminal, specifically, a cell is selected from the neighboring cells of the terminal as the Scell, the frequency point corresponding to the neighboring cell belongs to the CA frequency point set in the base station, and the signal quality of the neighboring cell is better than that of the current Scell of the terminal, which is the first cell.
By the method, the success rate of the terminal entering the CA state can be improved, so that the CA proportion of the terminal entering the CA state under the base station is improved.
In the embodiment of the invention, when a base station determines that a terminal meets a carrier aggregation condition, candidate auxiliary carrier SCC frequency points are determined from a carrier aggregation CA frequency point set of the base station, wherein the CA frequency point set at least comprises two different frequency points which are detected at the same position in a coverage area of the base station and meet a signal quality index; the base station sends A4 measurement control signaling to the terminal according to the candidate SCC frequency point; the base station determines a candidate secondary cell Scell of the terminal according to an A4 measurement report reported by the terminal; and if the base station establishes the connection between the primary cell Pcell of the terminal and the candidate Scell, determining the candidate Scell as the Scell of the terminal. The method is based on a CA frequency point set of a base station to carry out carrier aggregation, wherein the CA frequency point set at least comprises two different frequency points which are detected at the same position in the coverage area of the base station and accord with signal quality indexes, and because the cells and the frequency points are in a many-to-one relationship, namely a plurality of cells can share one frequency point, a plurality of base stations can use the same frequency point configuration mode, thereby reducing the configuration workload and improving the configuration efficiency when carrying out carrier aggregation.
