Abstract
In an instant messaging system, message latency is reduced by initiating traffic channel set-up at a receiving device concurrently while a sending device is generating the instant message. When a user begins generating an instant message, the sending device transmits a service request to a payload and connection server to indicate that an instant message is pending. Upon receipt of the service request, the payload and connection server notifies the receiving device so that the receiving device can initiate traffic channel set-up concurrently while the instant message is being recorded. When the traffic channel is established, the receiving device polls the server. If the instant message is not yet received by the payload and connection server when the polling request is received, the payload and connection server waits a predetermined period of time to receive the pending instant message and forwards the instant message when it is received.
