Method and apparatus for signalling between terminals
First Claim
1. A method of communications employing a predetermined communications protocol defining respective responses to predetermined events, said method comprising:
- separating said protocol into a first group of responses to corresponding first events, and a second group of responses to corresponding second events, wherein said first events occur frequently relative to said second events;
storing, at a communications user terminal which is external to but connected to a communications network via a communications channel, said first group of responses;
storing, at a store in or connected to the communications network, at least said second group of responses;
communicating from said user terminal using said first group of responses;
on detecting an event other than one of said first events at said user terminal, sending event-handling data from said store to said user terminal; and
communicating from said user terminal using said event-handling data.

Abstract
A method of communications employs a communications protocols defining respective responses to predetermined events. The protocol is separated into a first group of behaviours defining responses to corresponding first, relatively frequently occurring, events, and a second group of behaviours defining responses to corresponding first, relatively frequently occurring, events, and a second group of behaviours defining responses to corresponding second, relatively infrequently occurring events. The first group is stored at a user communications terminal. At least the second group is stored at a store remote from the user terminal, and interconnected therewith via a communications channel. Communication is established from the user terminal using first events. On detecting an event other than one of said the first events at the user terminal, event holding data is signaled from the store to the user terminal; and communication is established from the user terminal using the event-handling data.

8. A communications system comprising:
-
a telecommunications network;
a first terminal external to but connected to said network;
a second terminal interconnectable with the first terminal via said telecommunications network, and a store in or connected to said network;
in which;
the second terminal is arranged to communicate using a communications protocol defining a set of responses to respective conditions;
the first terminal stores, and is arranged to communicate using, a subset of said protocol; and
the store is arranged to cooperate with the first terminal for handling conditions requiring a response within the set but not within the subset earlier stored at the first terminal.

9. A communications terminal for use with a communications protocol defining a set of responses to respective predetermined events, said terminal comprising:
-
a communications port for connection to a telecommunications network via a communications channel, the communications terminal being external to the telecommunications network;
a signaling port for connection to said telecommunications network via a signaling channel; and
a store for storing data defining a core subset of said responses corresponding to a core subset of said events; and
a controller for controlling communications via the communications and signaling ports in accordance with said core subset of said responses;
the terminal being arranged to detect events not within said core subset, and to receive event-handling data via said signaling port, and the controller being arranged to handle said detected events in accordance with said received event-handling data. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
