It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion.
For the convenience of clearly describing the technical solutions of the embodiments of the present application, in the embodiments of the present application, the terms "first", "second", and the like are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the terms "first", "second", and the like do not limit the quantity and execution order.
With the development of network technology, the requirements of services between terminals on network speed are higher and higher, and the current single carrier network speed is difficult to meet the requirements of the terminals on services such as high definition video and the like. The carrier aggregation technology can improve the uplink and downlink network rates of the corresponding terminal by aggregating the bandwidths of a plurality of carriers so as to meet the network requirements of the terminal on services such as high-definition video and the like.
Currently, a carrier aggregation procedure of a terminal includes:
(1) the network management system configures a carrier aggregation cell set for the base station.
Specifically, the carrier aggregation cell set includes a primary cell and a secondary cell, and carrier aggregation of the terminal can be implemented only between the primary cell and the secondary cell in the carrier aggregation cell set.
(2) The terminal establishes an initial connection with the primary cell.
When the terminal enters the coverage area of the base station, the terminal resides in the frequency point of the main cell and establishes initial connection with the main cell.
(3) And the base station configures the secondary cell for the terminal according to the requirement.
Specifically, the configuration modes of the secondary cell include blind configuration and measurement-based configuration.
When the blind configuration switch of the auxiliary cell is closed, the base station can send an A4 measurement instruction to the terminal to instruct the terminal to measure the signal quality of the auxiliary cell in the carrier aggregation cell set, and the base station can configure the auxiliary cell for the terminal according to the measurement report reported by the terminal; and when the blind configuration switch of the auxiliary cell is turned on, the base station configures the auxiliary cell for the terminal according to the priority of the auxiliary cell in the carrier aggregation cell set.
Further, the blind configuration procedure of the secondary cell includes: after the terminal establishes Connection with the primary cell, the base station may configure the secondary cell with high priority as the secondary cell of the terminal through an RRC Connection Reconfiguration message; if the priorities of the secondary cells are the same, the base station can randomly select one blind allocation to the terminal. If the auxiliary cell blind configuration is successful, finishing the configuration process of the auxiliary cell; if the blind configuration of the secondary cell fails, the base station may configure the secondary cell of the next priority to the terminal until all the secondary cells traverse completely.
The measurement-based configuration includes: after the terminal establishes connection with the primary cell, the base station may indicate a measurement to a4 below the terminal to instruct the terminal to perform a4 measurement on the secondary cells according to their priorities; after receiving the a4 measurement reports of all the secondary cells, the base station may sort the secondary cells according to the network quality of the secondary cells, and configure the secondary cell with the best network quality to the terminal.
It should be noted that, after the terminal configures the secondary cell, if the base station receives the a2 measurement report reported by the terminal, the base station may issue an RRC Connection Reconfiguration message to the terminal through the primary cell, so that the terminal deletes the configured secondary cell.
(4) And the base station activates or deactivates the terminal in real time according to the traffic of the terminal.
The specific configuration procedure of the secondary cell may refer to technical means commonly used in the art, and is not described herein again. The measurement process of the terminal on the cell network quality relates to an a2 measurement report and an a4 measurement report, which respectively correspond to an a2 event and an a4 event, wherein the a2 event means that the signal quality of the serving cell is lower than a threshold value, and the a4 event means that the signal quality of the neighboring cell is higher than the threshold value.
For the configuration method of the secondary cells in carrier aggregation, the terminal usually determines the secondary cells for carrier aggregation according to the priority of the secondary cells in the carrier aggregation cell set, and since the priority of each secondary cell is fixed, the secondary cell determined by the base station for the terminal is also usually fixed, and the corresponding secondary cell cannot be adjusted according to the network requirements of the terminal and the network load, which may cause waste of network resources.
Based on the above problems, in this embodiment of the present application, a configuration device of a carrier aggregation secondary cell may determine, through a machine learning model, a carrier aggregation parameter of a terminal based on a network resource utilization rate of each cell in a carrier aggregation cell set, and parameters such as a support condition of the terminal to a frequency band corresponding to each cell in the carrier aggregation cell set, and a network quality of each cell, so as to indicate the secondary cell as a carrier aggregation of the terminal; because the determined auxiliary cells are related to the network resource utilization rate of each cell in the carrier aggregation cell set and the parameters such as the network quality of the terminal, when the parameters change, the auxiliary cells determined for the terminal also change continuously, so that the network resource utilization rate is improved in accordance with the network requirements of the terminal,

In some embodiments, the first parameter and the second parameter are obtained periodically. Referring to fig. 3, as shown in fig. 4, after the step S12, the method further includes:
s14, if the first target carrier aggregation parameter determined according to the first parameter and the second parameter in the current period is different from the second target carrier aggregation parameter determined according to the first parameter and the second parameter in the previous period, configuring a secondary cell for the terminal according to the first target carrier aggregation parameter.
As a possible implementation manner, the previous cycle refers to a cycle before the current cycle, the obtaining cycle of the first parameter and the second parameter may be T, and the cycle of the carrier aggregation parameter determined by the preset model is also T, that is, the network management system continuously updates the secondary cell configured for the terminal with the cycle of T.
Since the carrier aggregation parameter in the application is determined by the preset model according to the first parameter and the second parameter, when the first parameter and the second parameter change, the corresponding carrier aggregation parameter may also change, that is, the auxiliary cell corresponding to the terminal changes during carrier aggregation of the terminal, and at this time, the network management system may instruct the base station to delete the current auxiliary cell of the terminal for the terminal and configure a new auxiliary cell for the terminal.
It should be noted that, the first target carrier aggregation parameter and the second target carrier aggregation parameter are different, which means that any parameter index of the first target carrier aggregation parameter and the second target carrier aggregation parameter is different, and for example, any parameter of the uplink carrier aggregation support parameter, the downlink carrier aggregation support parameter, the uplink carrier aggregation frequency band, the downlink carrier aggregation frequency band, the priority corresponding to the uplink carrier aggregation frequency band, the priority corresponding to the downlink carrier aggregation frequency band, the number of carriers aggregated by the uplink carrier, or the number of carriers aggregated by the downlink carrier is different, which may cause a secondary cell that may be configured for the terminal by the network management system to change.
In this step, the method for determining the secondary cell for the terminal according to the first target carrier aggregation parameter and the second target carrier aggregation parameter may refer to steps S12-S13, which are not described herein again.
It should be noted that, before the network management system executes the method for configuring a carrier aggregation secondary cell provided in this application, the network management system also needs to configure a carrier aggregation cell set for the base station, and the secondary cells determined in this embodiment are all the secondary cells in the carrier aggregation cell set. And the terminal can establish connection with the main cell, and when the terminal establishes connection with the auxiliary cell, signaling communication can be carried out through the main cell.
After the base station configures the target auxiliary cell determined by the network management system to the terminal, the activation and deactivation process of the auxiliary cell can be carried out with the terminal according to the real-time service volume of the terminal.
The carrier aggregation cell set, the connection establishment between the terminal and the primary cell, and the activation and deactivation process of the secondary cell may refer to technical means commonly used in the art, and are not described herein again.
