Claim of US Patent No. 10,368,319

1. A method for adjusting a transmit power in a Global System for Mobile Communications (GSM) communications terminal, the method comprising:determining that a GSM communications terminal concurrently executes a first service on a first subscriber identity module (SIM) card and a second service on a second SIM card that are supported by the communications terminal, wherein a modem corresponding to the first SIM card is a first modem, and a modem corresponding to the second SIM card is a second modem;
adjusting steady-state transmit powers of the first modem according to a service type of the first service and the second modem according to a service type of the second service, so that a steady-state transmit power of a modem corresponding to a high-priority service in the first service and the second service is greater than or equal to a steady-state transmit power of a modem corresponding to a low-priority service in the first service and the second service, wherein the steady-state transmit power refers to a transmit power of a to-be-accessed service or a single-pass service within a period of time starting from successful access of the to-be-accessed service during execution of the single-pass service to releasing of either of the services; and the to-be-accessed service is the first service or the second service, and correspondingly, the single-pass service is a service, other than the to-be-accessed service, in the first service and the second service; and
wherein adjusting steady-state transmit powers of the first modem according to a service type of the first service and the second modem according to a service type of the second service, comprises:
determining priorities of the first service and the second service according to the service type of the first service and the service type of the second service, and
adjusting the steady-state transmit power of the modem corresponding to the high-priority service in the first service and the second service to be greater than or equal to the steady-state transmit power of the modem corresponding to the low-priority service in the first service and the second service.
