Network based muting of a cellular telephone
First Claim
1. A method of selectively muting a user signal produced in a wireless communication device of a wireless communication system during a wireless phone call to a conference bridge, the method comprising:
- activating a mute key on a wireless communication device;
receiving at the wireless communication system a first predetermined control signal from the wireless communication device;
stopping at the wireless communication system the communication of the user signal in response to activating the mute key;
wherein the first predetermined control signal is an error-checked signaling message in a communication protocol.

Abstract
A system and method for selectively muting a call of a wireless communication system. A first predetermined signal is received by the wireless communication system. The phone signal has a user signal associated with it. In response to the first predetermined signal, the wireless communication system pauses communication of the user signal to the end user while still maintaining the phone call between the wireless communication system and the conference bridge. In response to a second predetermined signal, the wireless communication system reiates communication of the user signal to the end user.
