Abstract:
A method of initiating a telecommunications transaction with associated at least first, second, third and fourth signals, the method comprising the steps of:setting up a low-bandwidth initial signalling path interconnecting a transmitting, over the initial signalling path, said first, transaction request, signal from the switching centre to the service control system, according to a first signalling protocol;transmitting, over the initial signalling path, said second signal in response to the first signal, from the service control system to the terminal, according to a signalling protocol different from the first signalling protocol, to request information for said initiation of said transaction,transmitting, over the initial signalling path said third signal, in reply to the second signal, from the terminal to the service control system, also according to a signalling protocol different from the first signalling protocol, to provide said information,in response to the said third signal, generating said fourth, transaction control, signal for transmission from the service control system to the switching centre to control said transaction.
