摘要： A lawful interception apparatus, a lawful interception target apparatus and a lawful interception system are provided. If a lawful interception target apparatus accesses a new communication network which has no lawful interception authority, the lawful interception apparatus receives intercept activation information from the lawful interception target apparatus through a communication network which has a lawful interception authority. The lawful interception apparatus performs seamless lawful interception on the lawful interception target apparatus by use of the received intercept activation information.

摘要： Provided are an electronic surveillance system and a method thereof. In the electronic surveillance system that performs electronic surveillance on a subscriber in a communication network, the electronic surveillance system includes: one or more communication service providers that provide retained data, which is information generated while the subscriber uses a communication service; a dedicated storage that stores and manages the retained data provided by the communication service providers; and a law enforcement agency that requests the dedicated storage to send electronic surveillance information on a specific subscriber so as to be provided with the surveillance information when the electronic surveillance information on the specific subscriber is required. Accordingly, retained data, which is subscriber electronic surveillance information is integrally managed and stored in a dedicated storage. Thus, a communication service provider can reduce costs when a law enforcement agency requests subscriber electronic surveillance information. Furthermore, the subscriber electronic surveillance information can be efficiently managed.
摘要翻译：提供电子监视系统及其方法。在对通信网络中的用户进行电子监视的电子监控系统中，电子监控系统包括：提供保留数据的一个或多个通信服务提供者，其是在用户使用通信服务时产生的信息; 专用存储器，用于存储和管理由通信服务提供商提供的保留数据; 以及执行机构，要求专用存储器在特定用户上发送电子监控信息，以便在需要特定用户的电子监视信息时提供监视信息。因此，作为用户电子监视信息的保留数据被整体管理并存储在专用存储器中。因此，当执法机构要求用户电子监控信息时，通信服务提供商可以降低成本。此外，可以有效地管理用户电子监视信息。

摘要： Disclosed is a communication vocoder. An encoder and a decoder in a first format, and a decoder in a second format are formed in the communication vocoder. The encoder in the first format encodes voice signals into voice packets in the first format, and the decoder in the first format decodes the voice packets in the first format into voice signals. When voice packets in the second format are input to the communication vocoder, the decoder in the second format decodes the voice packets in the second format into voice signals. The decoders in the first and second formats are formed as subroutines in the communication vocoder.

摘要： The LSF quantizer for a wideband speech coder comprises a subtracter for receiving an input LSF coefficient vector and removing a DC component from it; a memory-based vector quantizer and a memoryless vector quantizer for respectively receiving the DC-component-removed LSF coefficient vector and independently quantizing the same; a switch for receiving quantized vectors respectively quantized by the memory-based vector quantizer and the memoryless vector quantizer, selecting a quantized vector that has less quantized error that is a difference between the received quantized vector and the input LSF coefficent vector from among the received quantized vectors, and outputting the same; and an adder for adding the quantized vector selected by the switch to the DC component of the LSF coefficient vector.
