Abstract

A local services platform including a server subsystem is connected to one or more APs; an application subsystem and provides headset/terminals (HS) with real-time services. A streaming interface is installed between the server and the application. The HS is capable of being activated and paired with a host device, typically a telephone under standard Link Control Protocol. The HS includes an extra button, when operated, causes the host to place the HS in an “idle” mode. During the “idle” mode, the HS listens to AP inquiries or carries out inquiries. When an AP beacon is detected, the HS requests a HOLD state from the paired telephone and receives streaming data after completing a connection to the AP beacon. When the streaming data is in channels, the HS can switch among the channels or end the transmission by operating the idle button.
