US 2003/0147397 A1 · Establishing communication paths to law enforcement agencies

Abstract

A call is set up between a first communication device (101) and a second communication device (115) on a first communication path (117), via an asynchronous transfer mode (ATM) network (105). A second communication path (203) is established from the ATM network (105) to a law enforcement agency (201), which second communication path comprises audio sourced by the first communication device (101) on the first communication path (117). A third communication path (205) is established from the ATM network (105) to the law enforcement agency (201), which third communication path (205) comprises audio sourced by the second communication device (115) on the first communication path (117). The audio sourced by the first communication device (101) and the audio sourced by the second communication device (115) are replicated by an ATM switch (107) in the ATM network (105).

Dependent claims

A method comprising the steps of:

setting up a call on a first communication path, via an asynchronous transfer mode (ATM) network, between a first communication device and a second communication device;
establishing a second communication path from the ATM network to a law enforcement agency, which second communication path comprises audio sourced by the first communication device on the first communication path;
establishing a third communication path from the ATM network to the law enforcement agency, which third communication path comprises audio sourced by the second communication device on the first communication path;
wherein the audio sourced by the first communication device and the audio sourced by the second communication device are replicated by an ATM switch in the ATM network.

A method comprising the steps of:

setting up a first call, via an asynchronous transfer mode (ATM) network, between a first communication device and a second communication device;
establishing a first communication path from the ATM network to a law enforcement agency, which first communication path comprises audio sourced by the first communication device during the call;
establishing a second communication path from the ATM network to the law enforcement agency, which second communication path comprises audio sourced by the second communication device during the call;
when the first call is placed on hold by the first communication device and the first communication device places a second call to a third communication device, performing the steps of:
setting up the second call, via the ATM network, between the first communication device and the third communication device;
establishing a third communication path from the ATM network to the law enforcement agency, which third communication path comprises audio sourced by the first communication device during the second call;
establishing a fourth communication path from the ATM network to the law enforcement agency, which fourth communication path comprises audio sourced by the third communication device during the call;
wherein the audio sourced by the first communication device, the second communication device, and the third communication device is replicated by one or more ATM switches.
