Example one
Referring to fig. 1, fig. 1 is a flowchart of a downlink inter-band carrier aggregation configuration method in a first preferred embodiment of the present invention, where the configuration method is mainly used in a mobile terminal such as a mobile phone. The configuration method comprises the following steps:

The following describes each step of the downlink inter-band carrier aggregation configuration method in detail.
In step S101, each instruction in the operation process of the mobile terminal is monitored through a pre-installed program, and a start instruction of the downlink inter-band carrier aggregation function is identified from the each instruction. The starting instruction may be generated by manually operating the mobile terminal by the user, or may be automatically generated when the mobile terminal detects that the downlink network data amount of the user exceeds a certain threshold.
In step S102, when the start instruction is monitored, a first frequency band of a main carrier component and a second frequency band of an auxiliary carrier component of downlink inter-band carrier aggregation are obtained by querying, where in actual operation, the first frequency band of the main carrier component is often fixed, and the second frequency band of the auxiliary carrier component is selected according to a configuration of a mobile phone and a specific situation of a base station.
In step S103, since the first antenna and the second antenna are both provided with a pass band by a filter circuit, the filter circuit is usually based on a filter capacitor, and the filter capacitor is a capacitor with an adjustable capacitance value. The step S103 may specifically be:

In step S104, the primary carrier component is set to the first antenna, i.e. received and transmitted by the first antenna. The secondary carrier component is set to the second antenna, i.e., received and transmitted through the second antenna.
As can be seen from the above, the inter-downlink carrier aggregation configuration method provided by the present invention monitors the start instruction of the inter-downlink carrier aggregation function; when the starting instruction is monitored, acquiring a first frequency band of a main carrier component and a second frequency band of an auxiliary carrier component of the inter-downlink-band carrier aggregation; tuning the passband of the first antenna to a first frequency band and the passband of the second antenna to a second frequency band; setting a primary carrier component to the first antenna and a secondary carrier component to a second antenna; therefore, the existing antenna device which does not meet the inter-band carrier aggregation is configured to meet the inter-band carrier aggregation on the premise of not changing the physical structure of the original antenna.

The following describes each step of the downlink inter-band carrier aggregation configuration method in detail.
In step S201, each instruction in the operation process of the mobile terminal is monitored through a pre-installed program, and a start instruction of the downlink inter-band carrier aggregation function is identified from the each instruction. The starting instruction may be generated by manually operating the mobile terminal by the user, or may be automatically generated when the mobile terminal detects that the downlink network data amount of the user exceeds a certain threshold.
In step S202, when the start instruction is monitored, a first frequency band of a main carrier component and a second frequency band of an auxiliary carrier component of downlink inter-band carrier aggregation are obtained by querying, where in actual operation, the first frequency band of the main carrier component is often fixed, and the second frequency band of the auxiliary carrier component is selected according to the configuration of the mobile phone and the specific situation of the base station.
In step S203, since the first antenna and the second antenna are both provided with pass bands through the filter circuit, the filter circuit is usually based on a filter capacitor, and the filter capacitor is a capacitor with adjustable capacitance value. The step S103 may specifically be:
acquiring a first capacitance value according to a first frequency band; adjusting a capacitance value of a filter capacitance of the first antenna to the first capacitance value;

In actual testing, the first intensity value is averaged over a predetermined period of time, for example, 3 seconds or 4 seconds.
In step S206, if the first strength value is greater than or equal to the first predetermined value, it indicates that the current configuration state is better, and the signal strength is better.
In step S207, if the first strength value is smaller than the first predetermined value, it indicates that the signal strength of the current carrier is poor, and the configuration states of the first antenna and the second antenna need to be optimized. Specifically, the step S207 includes the following substeps:
s2071, if the first strength value is smaller than a first preset value, tuning the passband of the first antenna to a second frequency band, and tuning the passband of the second antenna to the first frequency band; in this step, tuning the passband of the first antenna to the second frequency band may be achieved by adjusting a capacitance value of a filter capacitor of the filter circuit of the first antenna, and tuning the passband of the second antenna to the first frequency band may be achieved by adjusting a capacitance value of a filter capacitor of the filter circuit of the second antenna.
S2072, after tuning, switching the primary carrier component to the second antenna, and switching the secondary carrier component to the first antenna, so that the first antenna and the second antenna enter a second configuration state;
s2073, detecting a second strength value of the downlink signal of the primary carrier component in the second configuration state;

comparing the first intensity value with the second intensity value;
if the second intensity value is greater than or equal to the first intensity value, keeping the first antenna and the second antenna in a second configuration state;
and if the second strength value is smaller than the first strength value, the first antenna and the second antenna are restored to the first configuration state.
As can be seen from the above, the inter-downlink carrier aggregation configuration method provided by the present invention monitors the start instruction of the inter-downlink carrier aggregation function; when the starting instruction is monitored, acquiring a first frequency band of a main carrier component and a second frequency band of an auxiliary carrier component of the inter-downlink-band carrier aggregation; tuning the passband of the first antenna to a first frequency band and the passband of the second antenna to a second frequency band; setting a primary carrier component to the first antenna and a secondary carrier component to a second antenna; therefore, the existing antenna device which does not meet the inter-band carrier aggregation is configured to meet the inter-band carrier aggregation on the premise of not changing the physical structure of the original antenna. Further, in this embodiment, the first strength value of the downlink signal of the main carrier component is detected; if the first intensity value is greater than or equal to a first preset value, keeping the first antenna and the second antenna in a current first configuration state; if the first strength value is smaller than a first preset value, optimizing configuration states of the first antenna and the second antenna; thereby further improving the communication quality of the downlink channel of the main carrier component.
