Document Type and Number:
WIPO Patent Application WO2000002411
Kind Code:
A3
Abstract:
A method of transmitting calling user addressing information in a telecommunications network using Signalling System No.7. A call set-up phase is conducted between two exchanges of the telecommunication network to reserve a channel for user data. During this set-up phase, an Initial Address Message is transmitted from the first exchange to the second exchange, the Initial Address Message containing an Application Transfer Mechanism indicator to notify the second exchange that addressing information will be transmitted in one or more subsequent Application Transfer Mechanism Messages. The said one or more Application Transfer Mechanism Messages are then transmitted from the first node to the second node, each message including a Unidirectional flag to indicate that the message relates to the basic call context application and not peer-to-peer association context.
