摘要： In one embodiment of a header-compression method, a 32-bit timestamp value is divided by a 16- or 8-bit stride value using a plurality of 16/8-bit division operations, each performed using a corresponding hardware instruction issued to an arithmetic logic unit (ALU) of the corresponding communication device, such as an access terminal or a base station of a communication system. When specialized 32/16-bit and/or 32/8-bit division-logic circuitry is not available in the ALU, embodiments of the header-compression method can advantageously be used to improve the speed and efficiency of timestamp compression in communication devices.
摘要翻译：在报头压缩方法的一个实施例中，使用多个16/8位分割操作，将32位时间戳值除以16位或8位步幅值，每个使用相应的硬件指令相应通信设备的算术逻辑单元（ALU），诸如通信系统的接入终端或基站。当专用的32/16位和/或32/8位分割逻辑电路在ALU中不可用时，报头压缩方法的实施例可以有利地用于提高通信设备中的时间戳压缩的速度和效率。

摘要： In one embodiment of a header-compression method, a timestamp value is divided by a stride value using a plurality of binary-shift operations corresponding to a Taylor expansion series of the reciprocal stride value in a base of ½. When the division-logic circuitry of an arithmetic logic unit in the corresponding communication device is not designed to handle operands that can accommodate the length of the timestamp and/or stride values, the header-compression method can advantageously be used to improve the speed and efficiency of timestamp compression in communication devices.
摘要翻译：在标题压缩方法的一个实施例中，使用对应于½的基础中的往复步幅值的泰勒展开序列的多个二进制移位操作，将时间戳值除以步幅值。当对应的通信设备中的算术逻辑单元的分割逻辑电路不被设计为处理可以适应时间戳和/或步幅值的长度的操作数时，报头压缩方法可以有利地用于提高速度和通信设备中时间戳压缩的效率。

摘要： In one embodiment, a method includes receiving a media signal associated with a session established based on a session request. The session request is defined at a session exchange device associated with a media over internet protocol (MoIP) network. The method also includes sending a portion of the media signal to a dual-tone multi-frequency (DTMF) analysis module during a sampling time period after a non-sampling time period.

摘要： In one embodiment, a method includes receiving a first internet protocol (IP) packet having information associated with a dual-tone multi-frequency (DTMF) signal. The information of the first IP packet is configured based on a protocol associated with a first layer of a media over internet protocol (MoIP) network. The first IP packet is associated with a destination endpoint. The method also includes producing a second IP packet having information associated with the DTMF signal. The information of the second IP packet is configured based on a protocol associated with a second layer of the MoIP network and a DTMF conversion policy associated with the destination endpoint. The second layer is different than the first layer.
