Adaptive mobile signaling for wireless internet telephony

[[abstract]]Active packets are utilized by a mobile terminal in a wireless network to set-up a wireless call via a signaling process, and for mobility management via a mobility process as the mobile terminal moves from one cell to another in a subnet. Active packets instantiate an agent in the fixed network to handle signaling between the mobile terminal and the fixed network, and then instruct the agent to negotiate setup of an open channel between the mobile terminal and the destination device. Moreover, active packets foster the handoff of the mobile terminal as the terminal moves from one cell to another in a subnet. Finally, the signaling process and mobility process are coordinated so that lost active packets are mitigated during roaming by the mobile terminal.[[department]]資工
