摘要： A multi-mode mobile terminal in an idle state switches between a CDMA system mode and a WCDMA system mode. If the intensity of a WCDMA signal is maintained below a threshold value for longer than a predetermined period in a WCDMA idle state, the acquisition of the CDMA system is attempted, and a WCDMA modem is deactivated if the acquisition of the CDMA system mode was successful. Alternatively, the acquisition of the WCDMA system is attempted at regular intervals in a CDMA idle state, and a CDMA modem is deactivated if the acquisition of the WCDMA system was successful. At least any one of the two modes can be maintained in an activated state when a mode is switched into another mode so that the duration of an interruption of service can be minimized.
摘要翻译：处于空闲状态的多模式移动终端在CDMA系统模式和WCDMA系统模式之间切换。如果在WCDMA空闲状态下WCDMA信号的强度维持在阈值以下长于预定时间段，则尝试CDMA系统的获取，并且如果CDMA系统模式的获取成功则WCDMA调制解调器被去激活。或者，在CDMA空闲状态下以规则的间隔尝试WCDMA系统的获取，并且如果WCDMA系统的获取成功，则CDMA调制解调器被去激活。当模式切换到另一模式时，两种模式中的至少任何一种可以保持在激活状态，从而可以最小化服务中断的持续时间。
