In this embodiment, as shown in fig. 4, if the dual-path filter 1022 includes the filtering unit 221 and the filtering unit 222, the frequency band corresponding to the filtering unit 221 is B39, the frequency band corresponding to the filtering unit 222 is B41, the tri-path filter 1021 includes the filtering unit 211, the filtering unit 212 and the filtering unit 213, the frequency band corresponding to the filtering unit 211 is B41, the frequency band corresponding to the filtering unit 212 is B3, and the frequency band corresponding to the filtering unit 213 is B1, where the dual-path filter 1022 and the tri-path filter 1021 each include the filtering unit corresponding to the frequency band B41.
In the case that the first selection switch 101 determines that the frequency band combination includes the frequency band B41 according to the frequency band configuration instruction, the first selection switch 101 may send a control instruction to the second selection switch 103 according to the determined target combiner filter, so that the second selection switch 103 is connected to the corresponding input terminal according to the target combiner filter. For example, the frequency band combination determined by the first selection switch 101 is b41+b3, and the determined target combined filter is a tri-combined filter, in this case, the first selection switch 101 sends a control instruction carrying a tri-combined filter identifier to the second selection switch 103, and when the second selection switch 103 determines that the tri-combined filter 1021 needs to be connected to the combined filter identifier in the control instruction, the switch input end corresponding to the tri-combined filter 1021 is connected to implement the connection of the filter unit corresponding to the B41 frequency band in the tri-combined filter 1021, which is not limited in this embodiment.
In this embodiment, under the condition that different combiner filters have filter units with the same frequency band, the control instruction controls the filter units with the same frequency band in one of the target combiner filters to be connected, so that the port utilization rate of the transceiver is simply and effectively improved.
