ABSTRACT:
A method and system for reducing latency in initiation of a real-time data session between wireless communication stations. In order to initiate a session with one or more target parties, an originating station will send a voice call origination message to a network switch, providing in the origination message (i) a session-initiation feature code and (ii) a target code indicative of the one or more target parties. The switch will then detect the session-initiation feature code as an intelligent-network trigger and responsively signal to a service controller, which will in turn signal to a communication server. The communication server will then invite the originating station and each of the one or more target parties to participate in the session, setting up a conference leg with each and bridging the legs together to allow the session to proceed.
