Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a cell switching method and apparatus.
Background
Micro base stations (Pico) are widely used in indoor network coverage scenes by virtue of the characteristics of small power, easy deployment and the like, so as to meet the increasing indoor network coverage capacity requirement.
The cell under the coverage of the micro base station is called a micro base station cell. In a scenario where multiple micro base station cells are deployed, since the number of micro base station cells exceeds a range of a specified Physical Cell Identifier (PCI), the same PCI within the PCI range may be reused by multiple micro base station cells. When User Equipment (UE) is handed over from a source cell to a micro base station cell (target cell), if the source cell already has an adjacent cell with the same PCI as that of the target cell, the source cell cannot add the target cell as the adjacent cell, and this PCI collision problem will cause the UE to fail to perform cell handover.
For example, as shown in fig. 1, the micro base station cell group includes a micro base station cell a and a micro base station cell B, and the PCI range configured by the micro base station cell group includes PCI 1, PCI 2, and PCI 3, that is, the micro base station cell a and the micro base station cell B included in the micro base station cell group may multiplex PCIs within the PCI range. When the UE moves from the macro base station cell to the micro base station cell A adjacent to the macro base station cell, the adjacent micro base station cell B is supposed to exist in the macro base station cell, the PCI of the micro base station cell B is 1, at the moment, the UE reports the PCI of the micro base station cell A to the macro base station cell to be 1, the micro base station cell A cannot be added to the macro base station cell to serve as the adjacent cell, and the UE cannot be switched to the micro base station cell A.
In summary, in a scenario where a plurality of micro base station cells configure specified PCI ranges, since the same PCI may be reused by the plurality of micro base station cells, that is, the PCIs configured by the micro base station cells collide, a problem that the UE fails to perform cell handover may be caused.

The sequence numbers of the embodiments of the present invention only represent the order of the embodiments, and do not represent the merits of the embodiments.

As shown in fig. 2, an embodiment of the present invention provides a cell handover method, including:
s201, a source cell receives a Physical Cell Identity (PCI) of a target cell reported by User Equipment (UE);
s202, a source cell determines the cell type of a target cell;
s203, when the source cell determines that the cell type of the target cell is the micro base station cell, acquiring a global cell identity (CGI) of the target cell;
s204, the source cell uniquely identifies the target cell according to the CGI and indicates the UE to be switched to the target cell.
In this embodiment, before the S201 source cell receives the physical cell identity PCI of the target cell reported by the UE, the method further includes:
the source cell acquires the relationship between the cell type and the PCI range corresponding to the cell type.
Namely, the source cell prestores the relationship between the cell type and the PCI range corresponding to the cell type.
The relationship between the cell type and the PCI range corresponding to the cell type at least includes: the correspondence between the micro base station cell (cell type is micro base station cell) and its corresponding PCI range. The cell type may further include a macro base station cell, a pico base station Femto cell, and the like, and therefore, the relationship between the cell type and the PCI range corresponding to the cell type may further include: the corresponding relationship between the macro base station cell and the corresponding PCI range, and/or the corresponding relationship between the pico base station cell and the corresponding PCI range.
In this embodiment, the relationship between the cell type and the PCI range corresponding to the cell type is configured based on the cell type of the cell and the PCI range allocated to the cell during network planning. It should be noted that the relationship between the cell type and the PCI range corresponding to the cell type may also be configured based on experience, and the configuration of the relationship between the cell type and the PCI range corresponding to the cell type is not limited to the method provided in this embodiment.
In this embodiment, in S202, the source cell determines, as the cell type of the target cell, the cell type corresponding to the PCI range in which the PCI reported by the UE is located according to the relationship between the cell type and the PCI range corresponding to the cell type.
It should be noted that, in this embodiment, the source cell may also determine the cell type of the target cell by using other methods, and is not limited to the method provided in this embodiment.
In this embodiment, in S201, the source cell receives a physical cell identity PCI of the target cell reported by the UE, and the source cell may receive the physical cell identity PCI of the target cell by receiving a measurement report reported by the UE, where the measurement report includes the PCI of the target cell.

s304, the source cell indicates the UE to report the CGI of the target cell;
s305, the UE reports the CGI of the target cell to the source cell;

After the UE moves from the source cell to the target cell, the UE can be switched from the source cell to the target cell by the cell switching method shown in fig. 3.
In the first embodiment, the source cell determines the cell type of the target cell according to the PCI of the target cell reported by the UE, and uniquely identifies the target cell according to the global cell identity CGI of the target cell reported by the UE and instructs the UE to switch to the target cell after determining that the cell type of the target cell is the micro base station cell. By the cell switching method provided in the embodiment, in a scenario where a plurality of micro base station cells configure a specified PCI range, if a target cell to which the UE is switched is a micro base station cell, since the same PCI may be multiplexed by the plurality of micro base station cells, the target cell to which the UE is switched cannot be identified through the PCI, that is, the UE fails to perform cell switching due to PCI collision configured by the micro base station cell.
Example two
Correspondingly to the embodiment, as shown in fig. 4, an embodiment of the present invention provides a cell switching apparatus, including:
an obtaining unit 401, configured to receive a physical cell identity PCI of a target cell reported by user equipment UE;

an obtaining unit 401, configured to obtain a global cell identity CGI of the target cell when the processing unit 402 determines that the cell type of the target cell is the micro base station cell;
the processing unit 402 is further configured to uniquely identify the target cell according to the CGI acquired by the acquiring unit 401, and instruct the UE to switch to the target cell.
In this embodiment, before receiving the physical cell identity PCI of the target cell reported by the user equipment UE, the obtaining unit 401 is further configured to:
the obtaining unit 401 obtains the relationship between the cell type and the PCI range corresponding to the cell type.
The relationship between the cell type and the PCI range corresponding to the cell type at least includes: the correspondence between the micro base station cell (cell type is micro base station cell) and its corresponding PCI range. The cell type may further include a macro base station cell, a pico base station Femto cell, and the like, and therefore, the relationship between the cell type and the PCI range corresponding to the cell type may further include: the corresponding relationship between the macro base station cell and the corresponding PCI range, and/or the corresponding relationship between the pico base station cell and the corresponding PCI range.
In this embodiment, the relationship between the cell type and the PCI range corresponding to the cell type is configured based on the cell type of the cell and the PCI range allocated to the cell during network planning. It should be noted that the relationship between the cell type and the PCI range corresponding to the cell type may also be configured based on experience, and the configuration of the relationship between the cell type and the PCI range corresponding to the cell type is not limited to the method provided in this embodiment.
In this embodiment, when the processing unit 402 determines the cell type of the target cell, the cell type corresponding to the PCI range in which the PCI received by the obtaining unit 401 is located is determined as the cell type of the target cell according to the relationship between the cell type and the PCI range corresponding to the cell type.
In this embodiment, when the obtaining unit 401 receives the physical cell identity PCI of the target cell reported by the UE, the physical cell identity PCI of the target cell may be received by receiving a measurement report reported by the UE, where the measurement report includes the PCI of the target cell. The processing unit 402 determines the cell type of the target cell as the micro base station cell by searching the relationship between the cell type and the PCI range corresponding to the cell type according to the PCI of the target cell reported by the UE.
Optionally, when receiving the measurement report reported by the UE, the obtaining unit 401 is specifically configured to:
an acquisition unit 401 sends a report measurement report request message to a UE;
the obtaining unit 401 receives a measurement report reported by the UE, where the measurement report includes the PCI of the target cell.
In this embodiment, after the processing unit 402 determines that the cell type of the target cell is the micro base station cell, the obtaining unit 401 indicates the UE to report the CGI of the target cell, and the obtaining unit 401 receives the CGI of the target cell reported by the UE. The processing unit 402 uniquely identifies the target cell according to the CGI of the target cell reported by the UE, and then the source cell adds the target cell as an adjacent cell and instructs the UE to switch to the target cell.
The CGI is composed of a location area identifier LAI and a cell identifier CID, where the LAI includes a mobile country code MCC, a mobile network code MNC, and a location area number LAC, that is, the CGI has a structure of MCC + MNC + LAC + CID.
Since the CGI of the target cell reported by the UE to the source cell needs to be in a non-connected state, and the CGI of the target cell reported by the UE to the source cell in a state of being connected to the source cell may cause disconnection between the UE and the source cell, in this embodiment, the PCI of the target cell is obtained by the obtaining unit 401, the cell type of the target cell is determined by the processing unit 402 using the PCI and a relationship between the cell type and a PCI range corresponding to the cell type, and it is further determined whether the UE needs to report the CGI of the target cell, that is, after the processing unit 402 determines that the cell type of the target cell is a micro base station cell, the obtaining unit 401 requests the UE to report the CGI of the target cell, and then the processing unit 402 uniquely identifies the target cell using the CGI.
The cell switching apparatus provided in this embodiment is used for a source cell, where the source cell is a macro base station cell, or a micro base station cell, or a pico base station Femto cell. It should be noted that the cell type of the source cell is not limited to the above cell types provided in this embodiment.
In the second embodiment, by using the obtaining unit 401 and the processing unit 402, specifically, the processing unit 402 determines the cell type of the target cell according to the PCI of the target cell reported by the UE received by the obtaining unit 401, and after determining that the cell type of the target cell is the micro base station cell, the processing unit 402 uniquely identifies the target cell according to the global cell identity CGI of the target cell obtained by the obtaining unit 401, and instructs the UE to switch to the target cell. With the cell switching apparatus provided in the second embodiment, in a scenario where a plurality of micro base station cells configure a specified PCI range, if a target cell to which a UE is switched is a micro base station cell, since the same PCI may be multiplexed by the plurality of micro base station cells, the target cell to which the UE is switched cannot be identified through the PCI, that is, a cell switching failure of the UE due to PCI collision configured by the micro base station cells may be avoided.
