    • PURPOSE: The radio frequency filter using volume acoustic resonator and radio frequency transceiver is capable of generating the narrow between the receiving and the transmission frequencies. CONSTITUTION: The radio frequency filter comprises two volume acoustic resonators (210, 220). The volume acoustic resonator (210) has a lower temperature coefficient of frequency lower than other volume acoustic resonators. And it is composed of the upper electrode, the lower electrode, the piezoelectric layer, and the temperature frequency coefficient compensation layer. The volume acoustic resonator (220) has a high quality factor than the volume acoustic resonator having a low temperature frequency coefficient. And it comprises the upper electrode, the lower electrode, and the piezoelectric layer. [Reference numerals] (210) Volume acoustic resonator with low frequency temperature coefficient; (220) Volume acoustic resonator with high quality factor

    • PURPOSE: Short message service (SMS) transmission method and device in a multi-subscriber identity module (SIM) mobile terminal are provided to transmit an SMS through a mobile communication provider network in which SMS transmission cost is relatively low. CONSTITUTION: When a transmission target SMS message is received from an input unit, a control unit of multi-SIM mobile terminal designates a SIM being in charge of SMS transmission in a plurality of SIMs mounted on a SIM providing unit (201). The control unit allows designation of the SIM being in charge of the SMS transmission to a user. The control unit transmits an SMS through a mobile communication service provider network of the designated SIM (203). [Reference numerals] (201) Designate a SIM among plurality of SIMs to be in charge of SMS transmission; (203) Transmit an SMS through a mobile communication service provider network of the designated SIM
    • 目的:提供多用户识别模块(SIM)移动终端中的短消息服务(SMS)传输方法和设备,用于通过SMS传输成本相对较低的移动通信提供商网络发送SMS。 构成:当从输入单元接收到传输目标SMS消息时,多SIM移动终端的控制单元指定在安装在SIM提供单元(201)上的多个SIM中负责SMS传输的SIM。 控制单元允许指定负责SMS传输的SIM卡给用户。 控制单元通过指定的SIM(203)的移动通信服务提供商网络发送SMS。 (附图标记)(201)在多个SIM中指定负责SMS发送的SIM; (203)通过指定SIM的移动通信服务提供商网络发送SMS
