Current terminal products may be classified into two types: dual SIM dual active products and dual SIM dual standby products. For a dual SIM dual active (DSDA) product, services on two SIMs can be performed at the same time. The services on the two SIMs are performed independently and do not affect each other. For a dual SIM dual standby (DSDS) product, due to a conflict between services on two SIMs at a radio frequency front end, the services on the two SIMs are performed in sequence. In other words, the services on the two SIMs are not performed at the same time due to the conflict. In a case of a conflict between the services on the two SIMs, the arbitration apparatus performs service preemption based on priorities of the services. A high-priority service may preempt a low-priority service, and the low-priority service can be performed only after the high-priority service ends. The current priorities of the services are as follows: a priority of a voice service>a priority of a data service.
