Problems solved by technology

[0011] None of these prior art discloses or proposes a short-distance terminal (headset in typical cases) adapted to switch the terminal to a host device (telephone in typical cases) To an "idle state" that puts the paired device in a passive state (typically the "hold" state) to receive streaming voice or listen to services from a voice beacon (typically an access point (AP)) , while disconnecting streaming voice when the master device becomes active

Embodiment Construction

[0032] A brief description of the short-range wireless system is appropriate before describing the preferred embodiment.

[0033] Typical ranges for short-range wireless systems are one hundred meters or less. They are often combined with systems that are wired to the Internet to provide long-distance communication. Such short-range wireless systems include wireless personal area networks (PANs) and wireless local area networks (LANs). Their common characteristic is that they operate in unlicensed parts of the radio frequency spectrum, typically in the 2.4GHz Industrial, Scientific and Medical (ISM) band or in the 5GHz unlicensed National Information Infrastructure (U-NII) band . Wireless personal area networks use low-cost, low-power radios with a typical range of ten meters. A well-known example of wireless personal area network technology is the Bluetooth Standard (Bluetooth Standard), which operates in the 2.4GHz ISM frequency band. It provides an air link speed of up ...

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.

Description

technical field [0001] The present invention relates to communication devices, systems and methods. In particular, the present invention relates to short-range radio terminals, systems and methods adapted to data streaming and real-time services. Background technique [0002] A short-range communication technology (typically Bluetooth) provides an active client with a Synchronous Connection-Oriented (SCO) link capable of transmitting a 64 kilobyte per second (KPS) channel. A data stream includes anything, but usually includes voice. The data stream can be added to a Bluetooth headset using a headset (headset) or a hands-free profile (hand-free profile). A Bluetooth access point (AP) acts as a Bluetooth voice beacon, that is, voice flows from the AP to the headset as an active terminal. The access point can also provide real-time location aware or listening services to the headset. However, the headset must be paired with a host device, such as a telephone, in order to pr...
