It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 illustrates a flow diagram of a communication control method according to some embodiments of the invention. As shown in fig. 1, the communication control method of this embodiment includes steps S102 to S104.
In step S102, the first base station determines a cell suffering from co-channel interference in a carrier aggregation cell, where the carrier aggregation cell includes a cell of the first base station.
A carrier aggregation cell refers to a cell that provides component carriers for aggregation used together. The terminal may access multiple carriers provided by the carrier aggregation cell for aggregation and perform uplink and downlink data transmission on the multiple carriers simultaneously.
The carrier aggregation cell is covered by one or more base stations, including a first base station. That is, in some embodiments, the carrier aggregation cells are all cells of the first base station. In some embodiments, the carrier aggregation cell comprises cells of a plurality of base stations, including a cell of a first base station.
In some embodiments, the co-channel interference is co-channel far-end interference. For example, when an IOT (average over Thermal) phenomenon is detected, it is determined that intra-frequency far-end Interference is generated.
In step S104, the first base station instructs the terminal in the cell suffering from co-channel interference to perform inter-frequency measurement, so that the terminal performs inter-frequency handover. Thus, the interfered user can switch to the pilot frequency of the same system to carry out service.
In the embodiment, the interfered user is switched to the same-system pilot frequency for service so as to avoid same-frequency interference, thereby avoiding the frame structure reconfiguration of the interfered cell and the base station, and reducing the resource waste as much as possible.
When the carrier aggregation cell is covered by a plurality of base stations, the first base station can instruct other base stations (such as a second base station) to issue a handover command to the interfered terminal through an interface between the base stations. Fig. 2 is a flow diagram illustrating a communication control method according to further embodiments of the present invention. As shown in fig. 2, the communication control method of this embodiment includes steps S202 to S208.
In step S202, the first base station determines a cell suffering from co-channel interference in a carrier aggregation cell, where the carrier aggregation cell includes a cell of the first base station and a cell of the second base station.
For example, a carrier aggregation cell includes cells 1-6, where cell 1-3 is covered by a first base station and cell 4-6 is covered by a second base station, and the first base station may obtain the interfered condition of cell 4-6 through its interface with the second base station.
The second base station means any base station participating in carrier aggregation other than the first base station. The carrier aggregation cell may further include cells of other base stations besides the first base station and the second base station, which is not described herein again.
In step S204, when the cell suffering from co-channel interference includes a cell of the first base station, the first base station issues a measurement signaling for inter-frequency handover to a terminal in the cell of the first base station suffering from co-channel interference.
After the interfered terminal reports the measurement report, the first base station sends a switching command to the terminals, so that the terminals covered by the first base station are switched to the different frequency of the same system to carry out service, and the same frequency interference is avoided.
In step S206, in case that the cell subjected to co-channel interference includes a cell of a second base station, the first base station sends a measurement indication to the second base station.
In step S208, based on the measurement indication, the second base station issues a measurement signaling for inter-frequency handover to a terminal in a cell of the second base station that is subject to co-channel interference.
After the interfered terminal reports the measurement report, the second base station sends switching commands to the terminals, so that the terminals covered by the second base station are switched to the different frequency of the same system to carry out service, and the same frequency interference is avoided.
The above embodiment utilizes the characteristic of carrier aggregation, and the same base station summarizes the interfered conditions of all cells, and triggers the inter-frequency handover process. Thus, co-channel interference can be avoided more efficiently. In addition, in the above embodiment, the interfered user is switched to the same-system pilot frequency for service to avoid the same-frequency interference, thereby avoiding the frame structure reconfiguration of the interfered cell and the base station, and thus reducing the resource waste as much as possible.
The inventor finds out through analysis that the same-frequency remote interference generally occurs in a specific time period, for example, early morning and early morning, and thus the method of the above embodiments may be performed in a preset time period. Fig. 3 illustrates a flow diagram of a communication control method according to further embodiments of the present invention. As shown in fig. 3, the communication control method of this embodiment includes steps S302 to S304.
In step S302, the first base station determines, within a preset time period, a cell that is subject to co-channel interference in a carrier aggregation cell corresponding to the first base station.
In some embodiments, the preset time period is a morning, early morning time period. For example, the preset time period is a time period between 0 pm and 7 am.
In step S304, the first base station instructs the terminal in the cell suffering from co-channel interference to perform inter-frequency measurement, so that the terminal performs inter-frequency handover.
The interfered terminal is switched to the pilot frequency within the preset time period in which the same-frequency far-end interference is easier to generate, so that the problem of terminal interference can be solved more specifically.
In some embodiments, the communication control method further includes step S306.
In step S306, in response to the end of the preset time period, the first base station instructs the terminal to switch to the frequency point used before performing the inter-frequency handover.
And under the condition that the cell subjected to the same frequency interference comprises the cell of the first base station, the first base station indicates the terminal of the first base station in the cell subjected to the same frequency interference to switch back to the original frequency point.
And under the condition that the cell subjected to the same frequency interference comprises a cell of a second base station, the first base station sends a switching instruction to the second base station. And after the second base station obtains the switching indication, the second base station indicates the terminal in the cell of the second base station, which is subjected to the same frequency interference, to switch back to the original frequency point.
The embodiment utilizes the characteristic that the occurrence time period of the remote co-frequency interference is relatively fixed, and the terminal is switched back to the original frequency point after the preset time period is finished, so that the ping-pong phenomenon of the terminal is avoided.
