Caller identification delivery in a wireless local loop or other systems
First Claim
1. A method of delivering an on-hook FSK-modulated Caller ID message from a CO to a telephone comprising the steps of:
- providing an incompatible network coupled between the CO and the telephone wherein a first network component of the incompatible network couples to the CO and a second network component of the incompatible network couples to the telephone;
establishing a communication link through the incompatible network between the first network component and the second network component;
communicating falsely to a CO that the second network component has begun a first ring cycle at the telephone after said establishing step has been accomplished;
transmitting an FSK-modulated Caller ID message from the CO to the first network component;
converting the FSK-modulated Caller ID message into an out-of-band message;
communicating the out-of-band message through the communication link to the second network component;
converting the out-of-band message at the second network component into the FSK-modulated Caller ID message; and
transmitting the FSK-modulated Caller ID message from the second network component to the telephone during a silent interval.

Abstract
A method of communicating FSK-modulated Caller ID signals through a network incompatible to the transmission of these signals is presented. A first network component couples between the incompatible network and a Central Office, and a second network component couples between the incompatible network and the telephone. In one embodiment, the call flow proceeds until the second network component would ring the line of the called party. The second network component seizes the line but does not apply a ringing signal. The second network component continues with the call flow as though the second network component had entered the silent interval after the first ring cycle at the called party. Subsequently, the CO transmits the FSK Caller ID information to the first network component which detects the FSK transmission and converts it into an out-of-band message and transmits the out-of-band message over the incompatible network to the second network component. Upon receipt of this out-of-band message from the first network component, the second network component converts it back into an in-band FSK Caller ID message, and delivers the FSK message during the first silent interval.
In another embodiment, the first network component, without sending signals to the second network component, initiates a call flow to the CO as though the second network component were entering the silent interval. Subsequently, the CO transmits the FSK Caller ID information to the first network component which detects the FSK transmission and converts it into an out-of-band message for transmission to the second network.
