    • PROBLEM TO BE SOLVED: To provide a method and apparatus for speech coding with improved speech quality.SOLUTION: A method for coding speech by a speech coder comprises the steps of: receiving an input signal; generating a target vector based on the input signal; generating a plurality of weighted adaptive codebook vectors based on a signal sub-sample resolution delay value, an adaptive codebook, and a weighted synthesis filter; generating a weighted fixed codebook (FCB) excitation vector based on the target vector and the plurality of weighted adaptive codebook vectors; generating a plurality of correlation terms based on the target vector, the plurality of weighted adaptive codebook vectors, and the weighted FCB excitation vector; and selecting a gain vector from a table in response to an error minimization criterion, where the gain vector consists of at least two adaptive codebook gains and one fixed codebook gain, and where the error minimization criterion is based on the plurality of correlation terms.

    • PROBLEM TO BE SOLVED: To provide a method and device for transmitting a short message service message to a wireless device.SOLUTION: A short message service center that locally maintains registration information indicating whether a wireless device is registered with a registrar receives a request for a short message service message. The short message service center determines, based on the maintained information, whether the wireless device is registered with the registrar, and transmits the short message service message to the wireless device through a session initiation protocol network with the determination that the wireless device is registered. If the wireless device is not registered with the registrar, the short message service center determines whether the wireless device is registered with a circuit services network, and transmits the short message service message to the wireless device through the circuit services network with the determination that the wireless device is registered with the circuit services network.
    • 要解决的问题:提供一种用于向无线设备发送短消息服务消息的方法和设备。 解决方案:本地维护指示无线设备是否向注册器注册的注册信息的短消息服务中心接收到对短消息服务消息的请求。 短消息服务中心基于所维护的信息确定无线设备是否向注册器注册,并且通过会话发起协议网络向无线设备发送短消息服务消息,并确定无线设备被注册。 如果无线设备未向注册器注册,则短消息服务中心确定该无线设备是否向电路服务网络注册,并通过电路服务网络将该短消息服务消息发送到无线设备, 无线设备在电路服务网络中注册。 版权所有(C)2012,JPO&INPIT
