Title:
【発明の名称】衛星通信の隠密傍受のための方法
Document Type and Number:
Japanese Patent JP2002519932
Kind Code:
A
Abstract:
In a satellite communication system, a method of unobtrusively intercepting a communication call includes establishing a first connection to originate from a first satellite subscriber (SU) and terminate at a first node at a first transcoder, establishing a second connection to originate from a second node at a second transcoder and terminate at a second SU, switching the first connection to originate from the first SU and terminate at a third node at the second transcoder, passing a first information carried by the first connection at the third node to the second connection at the second node. The first information without substantial delay or processing is transmitted by the second connection to be received by the second SU. The first information may be decoded in a decoder portion of the second transcoder to produce a first decoded information. The first decoded information, accordingly, may unobtrusively be monitored.
