Abstract:
A terminal 300 arranged to initiate a call or indicate an incoming call with a voiced alert and methods thereof, the terminal including a receiver 303 for receiving a signal corresponding to a call alert, a processor 309 for determining that the signal is a call alert signal corresponding to the voiced alert and for providing an alert signal corresponding to the voiced alert; and an audio transducer 317 coupled to the alert signal corresponding to the voiced alert for generating a user perceptible voiced alert. The terminal for initiating includes an audio transducer 321 for converting a caller party voiced signal to an alert signal and a processor 309 for generating a call alert signal corresponding to the alert signal; and a transmitter 305 for sending the call alert signal corresponding to the alert signal to a network and thereby to the called party.
Abstract:
A communication system for exchanging session initiation protocol signaling messages between a user host associated with a wireless communication device, and a remote user host, through a network, and method therefor. A multiplexer module positioned within the wireless communication device multiplexes call control data, session initiation protocol commands, and packet data setup and status transmitted between the wireless communication device and the network. A control module located in the multiplexer determines whether a packet associated control channel has been set up, and, in response to the packet associated control channel not being set up, the multiplexer module utilizes a slow dedicated control channel for transmitting signaling associated with requesting a packet associated control channel for transmitting the session initiation protocol commands.
