Data communications system with session control
First Claim
1. A method of operation of a data conmnunications system with session control having a data communications network and at least a first communications device, a second communications device and a third communications device in communications with the data communications network, the method comprising in the data communications network the steps of:
- identifying a fault status change in communications with the first communications device;
generating a session control command responsive to the step of identifying the fault status change, the session control command including an identification number; and
sending the session control command to at least the secondcommunications device and the third communications device.

Abstract
A method of operation of a data communications system (5) with session control having a data communications network (10) and at least a first communications device (1), a second communications device (2) and a third commnunications device (3) in communications with the data communications network (10). The data communications network (10) identifies a fault status change in communications with the first communications device (1), generates a session control command (6) with an identification number (7) attached responsive to identifying the fault status change and sending the session control command (6) to at least the second and the third communications devices (2 and 3). At least at the second communications device (2), the second communications device (2) receives the session control command (6), deter-mines from the identification number (7) whether the second communications device (2) is affected by the fault status change and selectively performs a session control action in response thereto.

5. A user terminal comprising:
-
a receiver that receives a message including a session control command indicative of a change in fault status sent to a plurality of user terminals; a message decoder coupled to the receiver that decodes the message and identifies the session control command including an identification number relevant to the user terminal; and a session manager coupled to the message decoder operative to perform a session control action in response to the session control command. - View Dependent Claims (6, 7, 8, 9)

10. A data communications system comprising a network device and a plurality of terminals, the network device comprising a fault detector and a command generator responsive to the fault detector to generate a session control command having an identification number and to send the session control command to a plurality of terminals,
wherein at least one terminal comprises: -
a receiver that receives a message sent to said plurality of user terminals; a message decoder coupled to the receiver that decodes the message and identifies the identification number in the session control command as being relevant to the at least one terminal; and a session manager coupled to the message decoder operative to perform a session control action in response to the session control command. - View Dependent Claims (11)

12. A data communications system comprising:
-
a data communications network; at least a first host computer connected to the data communications network; a group of at least two user terminals in communications with the data communications network; a fault detector associated with the data communications network for identifying a fault in communications with at least the first host computer; and a command generator which is responsive to the fault detector for generating a session control command and sending the session control command to the group of at least two user terminals. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
