Abstract: A method for processing concurrent services and a terminal can effectively ensure that a service with a higher service priority maintains better service transmission quality in the concurrent services. The concurrent services include a first service and a second service. A service priority of the first service is higher than a service priority of the second service. The method includes: obtaining, by a terminal, channel quality information of a channel that carries the concurrent services; and blocking, by the terminal, the second service when the channel quality information meets a preset blocking condition.

Abstract: A variable capacitor-based antenna adjustment method and a related apparatus. A first signal strength of a first communications system with a highest priority that is supported by an antenna having a variable capacitor is detected, and when the first signal strength is relatively strong to meet a first release condition, a capacitance value of the variable capacitor is adjusted to a preset capacitance value, where the preset capacitance value is closer to a second capacitance value corresponding to a working frequency band of a second communications system supported by the antenna, so that a working frequency band of the antenna having the variable capacitor is closer to the working frequency band of the second communications system, and therefore, communication quality of the second communications system is improved.

Abstract: A signal transmission method and system, and a controller are disclosed. The controller controls a single-pole double-throw switch by determining whether a signal status of a first signal with a higher priority satisfies a service requirement; and if the service requirement is not satisfied, guides a mixed signal of the first signal and a second signal that is received by an antenna to a processing back-end of the first signal by using the single-pole double-throw switch; or if the service requirement is satisfied, guides a mixed signal of the first signal and a second signal that is received by an antenna to a power splitter by using the single-pole double-throw switch, and separately transfers the mixed signal of the first signal and the second signal to a processing back-end of the first signal and a processing back-end of the second signal by using the power splitter.
