    Abstract: Un método para transiciones eficientes entre estados operativos en una red de comunicación, comprendiendo el método las etapas de: tener una estación de telefonía móvil en un estado Inactivo; requerir una transferencia de datos; pasar la estación de telefonía móvil del estado Inactivo a un estado Activo; y caracterizado por establecer una conexión entre una Función de Encaminamiento de IP (106) y una Función de Portadora de RF (110) de manera que una conexión existente desde la Función de Encaminamiento de IP (106) a una Función de Control de Localización (108) es modificada de manera que la conexión ahora finaliza en la Función de Portadora de RF (110) sin pasar a través de la Función de Control de Localización (10$); donde la Función de Portadora de RF (110) es: i) un equipo de Sitio de Base y un Selector, ii) un Selector y una o más Estaciones de Emisor - Receptor de Base, iii) un Selector y una o más Estaciones de Base, o iv) uno o más Puntos de Acceso; y la Función de Control de Localización (1Q$) es: i) una Función de Control de Paquetes, o ii) un Controlador de Localización de un Controlador de Punto de Acceso Celular (107).

    Abstract: In a CDMA wireless communication system (200) a dispatch call can be established between two CDMA mobile stations (202, 226), or between other mobile stations and the CDMA mobile station, or between a CDMA mobile station and a computer(236) located outside of the wireless system. To reduce the delay normally association with call set up in a CDMA system, a dispatch processing network (128, 144) is provided in addition to a telephony switch (118). Dispatch calls and call set up requests are routed to the dispatch processing network from the radio access network (110) which includes base stations (204, 206). Once a dispatch call request is made, while the dispatch processing network begins setting up a traffic channel for the originating mobile communication device, the target is also paged, and upon responding, set up on a traffic channel. The concurrence of establishing radio links with the target and originating communication devices substantially reduces dispatch call set up time.

    Abstract: An apparatus (200) checks voice quality when in a vocoder bypass mode. If the voice quality level is beyond an acceptable range, the apparatus (200) ends the vocoder bypass mode and returns to tandem vocoding. For example, a vocoder bypass controller (206) includes a speech quality detector (225) that determines the speech quality level of speech information based on at least one of detected volume level, echo level and noise level of the speech information. The vocoder bypass controller (206) with the speech quality detector (225) outputs a speech quality-based vocoder bypass control signal (236) to selectively activate or deactivate a vocoder bypass operation in response to the speech quality-based vocoder bypass control signal (236).

    Abstract translation: 当声码器旁路模式时,装置(200)检查语音质量。 如果语音质量级别超出可接受范围,则装置(200)结束声码器旁路模式并返回到串联声码。 例如,声码器旁路控制器(206)包括语音质量检测器(225),其基于语音信息的检测音量,回声电平和噪声电平中的至少一个来确定语音信息的语音质量水平。 具有语音质量检测器(225)的声码器旁路控制器(206)输出基于语音质量的声码器旁路控制信号(236),以响应于基于语音质量的声码器旁路控制信号选择性地启动或停用声码器旁路操作( 236)。

    Abstract: An improved non-linear processor used in echo cancellation eliminates a comfort noise source (214) and instead inputs a control signal (224) directly into a noise suppression system (403). The noise suppression system (403) uses the control signal (224) to inhibit the iterative update of the background noise estimate when the control signal (224) is active, which prevents any residual echo from biasing the noise estimate provided by the noise suppression system (403). Additionally, the control signal (224) is used by a gain calculator (533) within the noise suppression system (403) to attenuate each frequency band to the maximum allowable amount plus the current residual channel signal-to-noise ratio (SNR). Depending on the implementation, the noise suppression system (403) models the background noise of either a user of the PSTN or a user of a mobile station.
