Abstract

The disclosed for extending both Bluetooth speech gateway and Bluetooth mobile phone business and function comprises: defining the necessary message structure for extending business and function to package into a self-defined area specified by TCS protocol and form a special message; building ACL and CTP connection between multiple or one Bluetooth mobile phone and the Bluetooth speech gateway, and using former special message as the request and response message to extend business or function beyond the CTP and IntP standard. This invention is compatible to standard Bluetooth protocol.

Description

technical field [0001] The invention relates to the field of wireless personal area network (WPAN), in particular to bluetooth technology, more specifically, a method for expanding the services and functions of bluetooth voice gateways and bluetooth mobile phones. Background technique [0002] Bluetooth (Bluetooth), as a small-scale wireless connection technology, can realize convenient, flexible, safe, low-cost, low-power data and voice communication between devices, and is currently one of the mainstream technologies for realizing wireless personal area networks. In order to meet the needs of short-distance wireless voice telephony, the Bluetooth SIG organization formulated the Bluetooth Cordless Telephony Profile (Cordless Telephony Profile) and the Bluetooth Intercom Profile (Intercom Profile), which realized the use of Bluetooth technology in three-in-one phones (3-in-1 phone ) in the application (as shown in Figure 1), three kinds of applications include: access to the...
