Abstract:
A method of sending information between a message protocol compatible terminal in a message protocol communications network and a gateway to a stimulus signalling protocol communications network, comprising the steps of:(i) establishing a first deactivated, two-way, communications channel between said terminal and said gateway; (ii) opening a second two-way communications channel between said gateway and said terminal, said second two-way communications channel being associated with said first deactivated, two-way communications channel; (iii) sending stimulus signalling protocol information over said second two-way communications channel; (iv) detecting when information is about to be sent via said first, deactivated, two-way communications channel, on the basis of said stimulus signalling protocol information sent over the second, two-way communications channel and, if information is about to be sent via said first, deactivated, two-way communications channel, activating said first two-way communications channel; and (v) sending information over said first, activated two-way communications channel.
