In order to solve the above technical problem, embodiments of the present application provide a method and an apparatus for controlling a TWS headset.
Hereinafter, the TWS headset control method provided in the embodiments of the present application will be described and explained in detail through several specific embodiments.

The average packet supplementing rate is determined according to the number of data packets sent to the auxiliary earphone by the main earphone in the monitoring period and the number of data packets received by the main earphone to the terminal in the monitoring period.

That is, in each period, a communication link (listening link) bandwidth period and a primary-secondary link bandwidth period are divided. And after the first earphone of the main earphone receives the data packet sent by the terminal in each time period, the ACK is replied through the communication link, and the data sent is confirmed to be received without errors. As shown in fig. 5, in the 2 nd period, when it is detected that the difference between the short-time packet complementing rate of the first earphone of the master earphone and the average packet complementing rate is greater than the preset value, an event trigger flag mode _ switch is generated to be 1, and when it is detected that the event trigger flag mode _ switch is 1, the bandwidth period condition is detected.

In one embodiment, the third packet complementing rate is equal to the number of data packets sent by the second headset to the first headset in the second initial period/the number of data packets received by the second headset to the terminal in the second initial period.
In one embodiment, the first initial period and the second initial period have the same duration, that is, the second packet complementing rate and the third packet complementing rate have the same time, so that the primary and secondary handover decisions based on the magnitude relationship between the second packet complementing rate and the third packet complementing rate are more accurate.
