Fig. 2 is a flowchart of a carrier aggregation control method according to another embodiment of the present invention, as shown in fig. 2, the method includes:
In the embodiment of the invention, each step is executed by the base station.
In the embodiment of the present invention, one cycle includes a plurality of sampling time periods, and then the current cycle includes a plurality of sampling time periods. For example: one period includes 1 hour, then the current period includes 1 hour. When a terminal is handed over from another cell to a target cell, the terminal needs to send a Radio Resource Control (RRC) connection request to a base station where the target cell is located. In the embodiment of the invention, the base station can respond to the RRC connection request sent by the terminal and allow the terminal to access the cell under the base station, wherein the target cell and other cells are respectively provided with corresponding base stations which are responsible for the contact and control of the mobile communication of the cell. When the terminal is handed over from another cell to the target cell, the terminal needs to send an RRC release request to the base station where the other cell is located, and then sends an RRC connection request to the base station where the target cell is located.
When a base station receives an RRC connection request sent by a terminal in the current period, the RRC connection request carries a time point for sending the RRC connection request, a sampling time period in which the time point of the RRC connection request is located is obtained, and the number of RRC connection users in the sampling time period is added by 1. For example, one cycle is 1 hour, and one cycle includes 6 sampling time periods, i.e., sampling time period a, sampling time period b, sampling time period c, sampling time period d, sampling time period e, and sampling time period f, respectively, i.e., each sampling time period is 10 minutes. For example, 8: 00 to 9: 00 is a period, where 8: 00 to 8: 10 is a sampling period a, 8: 11 to 8: 20 is a sampling period b, 8: 21 to 8: and 30 is a sampling time period c, and the base station performs sampling at 8: 05, receiving an RRC connection request sent by the terminal, where a sampling actual period where a time point of acquiring the RRC connection request is located is a sampling time period a, for example, the number of RRC connection users acquiring the sampling time period a is 50, and the number of RRC connection users of the sampling time period a is added by 1, where at this time the number of RRC connection users of the sampling time period a is 51.
In the embodiment of the invention, the base station can respond to the RRC release request sent by the terminal and allow the terminal to leave the cell under the base station. When the terminal is handed over from the target cell to another cell, the terminal needs to send an RRC connection request to the base station of the other cell after sending an RRC release request to the base station of the target cell. When the base station receives an RRC release request sent by the terminal, the RRC release request carries a time point for sending the RRC release request, a sampling time period in which the time point of the RRC release request is located is obtained, and the number of RRC connection users in the sampling time period is reduced by 1. For example, one cycle is 1 hour, and one cycle includes 6 sampling time periods, i.e., sampling time period a, sampling time period b, sampling time period c, sampling time period d, sampling time period e, and sampling time period f, respectively, i.e., each sampling time period is 10 minutes. For example, 8: 00 to 9: 00 is a period, where 8: 00 to 8: 10 is a sampling period a, 8: 11 to 8: 20 is a sampling period b, 8: 21 to 8: and 30 is a sampling time period c, and the base station performs sampling at 8: at 25, receiving an RRC release request sent by the terminal, where a sampling time period where the time point of acquiring the RRC release request is located is a sampling time period c, for example, the number of RRC connection users acquiring the sampling time period c is 55, the number of RRC connection users of the sampling time period c is subtracted by 1, and at this time, the number of RRC connection users of the sampling time period c is 54.
In the embodiment of the present invention, if the RRC release request sent by the terminal is received first and then the RRC connection request sent by the terminal is received in the current period, step 202 is executed first and then step 201 is executed. The present invention does not limit the execution sequence of step 201 and step 202.
In the embodiment of the present invention, for example, each sampling time period receives an RRC connection request sent by a terminal or an RRC release request sent by the terminal, and the number of RRC connection users counted up to each sampling time period is shown in table 1 below:
TABLE 1
As shown in table 1 above, the maximum number of RRC connection users in the current cycle is selected from the number of RRC connection users in a plurality of sampling periods to be 60.
In the embodiment of the present invention, when the terminal is switched from another cell to the target cell, and the terminal sends an RRC connection request to the base station where the target cell is located, the terminal periodically sends a Measurement Report (MR for short) to the base station. The plurality of RESOURCE occupation quantities include the number of PHYSICAL RESOURCE BLOCKs (PRBs) occupied by the downlink PHYSICAL Channel, the number of PRBs occupied by the uplink PHYSICAL Channel, and the number of Control Channel Elements (CCEs) occupied by the PHYSICAL downlink Control Channel.
In the embodiment of the present invention, for example, when only one terminal is accessed in a cell, of a plurality of resource occupation quantities of the accessed terminal, the number of PRBs occupied by a downlink physical channel is 100, the number of PRBs occupied by an uplink physical channel is 150, and the number of CCEs occupied by a physical downlink control channel is 120, then of the plurality of resource occupation quantities of the cell, the number of PRBs occupied by the downlink physical channel is 100, the number of PRBs occupied by the uplink physical channel is 150, and the number of CCEs occupied by the physical downlink control channel is 120.

step 205', when multiple terminals access the cell, add the multiple resource occupation numbers of the multiple accessed terminals obtained in the current period to obtain the multiple resource occupation numbers of the cell obtained in the current period.
In the embodiment of the present invention, for example, when a terminal a, a terminal B, and a terminal C access a cell, among a plurality of resource occupation numbers of the terminal a, the number of PRBs occupied by a downlink physical channel is 100, the number of PRBs occupied by an uplink physical channel is 150, and the number of CCEs occupied by a physical downlink control channel is 120; in the plurality of resource occupation quantities of the terminal B, the number of PRBs occupied by the downlink physical channel is 90, the number of PRBs occupied by the uplink physical channel is 120, and the number of CCEs occupied by the physical downlink control channel is 100; in the plurality of resource occupation numbers of the terminal C, if the number of PRBs occupied by the downlink physical channel is 120, the number of PRBs occupied by the uplink physical channel is 200, and the number of CCEs occupied by the physical downlink control channel is 150, then in the plurality of resource occupation numbers of the cell, the number of PRBs occupied by the downlink physical channel is 310, the number of PRBs occupied by the uplink physical channel is 390, and the number of CCEs occupied by the physical downlink control channel is 370.
And step 206, dividing the number of the occupied resources of the cell acquired in the current period by the available number of the resources of the cell acquired in the current period to obtain the resource utilization rate corresponding to the number of the occupied resources.
In the embodiment of the invention, the base station can acquire a plurality of available resource quantities of the cell in advance, and each occupied resource quantity corresponds to one resource utilization rate. The number of the available resources includes the number of PRBs available for the downlink physical channel, the number of PRBs available for the uplink physical channel, and the number of CCEs available for the physical downlink control channel.
In the embodiment of the present invention, the resource utilization rates include an uplink PRB utilization rate, a downlink PRB utilization rate, and a PRB utilization rate of a downlink CCE.
Wherein the content of the first and second substances,

In the embodiment of the present invention, for example, the first threshold is 25% and the second threshold is 50. If the maximum resource utilization rate of the current period is less than or equal to the first threshold and the maximum number of RRC connection users of the current period is less than or equal to the second threshold, it indicates that the resource occupation of the cell is less at the moment, the number of connected users is less, and the carrier aggregation instruction for starting the cell is executed, so that the perception of the users can be improved, and the balance between the capacity and the perception can be guaranteed.
In this embodiment of the present invention, the executing the carrier aggregation instruction for starting the cell includes:
a main carrier cell and an auxiliary carrier cell of a cell are mutually matched into a pilot frequency adjacent cell;

And after the configuration of the auxiliary carrier activation parameters of the cell is finished, sending a carrier aggregation starting instruction to a terminal so that the terminal receives data sent by the base station according to the carrier aggregation starting instruction.

If the maximum resource utilization rate of the current period is greater than or equal to the third threshold, it indicates that the resource occupation of the cell is large at this time, and the large service user occupies the large resource, which may result in poor perception of other users, so that executing the carrier aggregation instruction for closing the cell can improve the perception of the user and ensure the balance of capacity and perception.
In this embodiment of the present invention, after executing the carrier aggregation instruction to close the cell, the method further includes: and configuring a secondary carrier deactivation parameter of the cell. The auxiliary carrier wave deactivation parameters comprise a carrier wave management switch, a service rate deactivation threshold, a service cache length deactivation threshold and an auxiliary carrier wave deactivation CQI threshold.
For example, when configuring the secondary carrier deactivation parameter of the cell, the carrier management switch is set to on, the service rate deactivation threshold is set to 100kbps, the service cache length deactivation threshold is set to 3Kbyte, and the secondary carrier deactivation CQI threshold is set to 5.

If the maximum number of the RRC connection users in the current period is greater than or equal to the fourth threshold, it indicates that the number of the RRC connection users in the cell is large, and the large number of resources occupied by the excessive users may result in poor perception of other users.
And after the configuration of the auxiliary carrier deactivation parameters of the cell is completed, sending a carrier aggregation closing instruction to the terminal so that the terminal receives data sent by the base station according to the carrier aggregation closing instruction.
If the maximum resource utilization rate of the current period is greater than the first threshold and smaller than the third threshold and the maximum number of RRC connection users of the current period is greater than the second threshold and smaller than the fourth threshold, the next period is taken as the current period, and step 201 is continuously performed.
In the embodiment of the invention, if the maximum resource utilization rate of the current period is greater than the first threshold and less than the third threshold and the maximum RRC connection user number of the current period is greater than the second threshold and less than the fourth threshold, the condition that the resource occupation of the cell is normal at the moment and the RRC connection user number is normal is indicated, and the maximum RRC connection user number and the maximum resource utilization rate of the next period are continuously detected, so that the carrier aggregation is effectively started or closed in real time, the balance of capacity and perception is ensured, and the perception of the user is improved.
