Message handling in a telecommunications network
First Claim
1. A message handler for the transmission and/or reception of message packets in one or both directions between a telecommunications station and a controller for one or more telecommunications stations, the message handler having a plurality of control layers including:
- a transmitter and/or receiver control layer operable to transmit and/or receive strings of characters between the controller and the telecommunications stations via a transmission line;
a call control layer, above the transmitter/receiver layer, for establishing and maintaining connection with the transmission line when message packet transmission is required;
a security layer, above the call control layer, for an exchange of authentication messages between the controller and the telecommunications stations to verify an identity of elements of the telecommunications station during establishment of a call connection.

Abstract
A message handler for the transmission and/or reception of message packets in one or both directions between a telecommunications station and a controller for one or more telecommunications stations, has a number of control layers including a transmitter and/or receiver control layer for the transmission and/or reception of strings of characters between the controller and the telecommunications stations via a transmission line, a call control layer, above the transmitter/receiver layer, for establishing and maintaining connection with the transmission line when message packet transmission is required and a security layer, above the call control layer, for the exchange of authentication messages between the controller and the telecommunications stations to verify the identity of elements of the telecommunications station during the establishment of a call connection. A simulator for testing and/or monitoring purposes can be connection to the transmission line between a telecommunications station and the controller. The simulator includes a message handler of the type described above for intercepting messages sent on the transmission line and a protocol monitor for monitoring intercepted messages from the transmission line and routing the messages to their original destination.

5. A simulator for connection to a transmission line between a telecommunications station and a controller for one or more telecommunications stations, the simulator comprising a transmission line interface including a message handler for intercepting messages sent on the transmission line and a protocol monitor for monitoring intercepted messages from the transmission line and routing the messages to their original destination, the message handler having a plurality of control layers including:
-
a transmitter and/or receiver control layer for transmission and/or reception of strings of characters between the controller and the telecommunications stations via a transmission line; a call control layer, above the transmitter/receiver layer, for establishing and maintaining connection with the transmission line when message packet transmission is required; a security layer, above the call control layer, for an exchange of authentication messages between the controller and the telecommunications stations to verify an identity of elements of the telecommunications station during establishment of a call connection. - View Dependent Claims (6, 7, 8, 9)
