Description
Technical field
The present invention relates to Bluetooth Communication Technology, keep technology in particular to bluetooth conversation and mobile network dial-up.
Technical background
Bluetooth is a kind of short-distance wireless communication technology, and it is operated in industry science doctor (ISM) frequency range of 2.4GHz.The piconet (Piconet) that the basic network topology of bluetooth is made up of a main control device and maximum seven slaves adopts the mode of time division multiple access (TDMA) to communicate between main control device and the slave.Utilize Bluetooth technology, can various device be coupled together in low-cost mode.The special interest group of bluetooth (Special Interest Group is called for short SIG) is the non-government organization that formulates and instruct Bluetooth specification and application.According to the Bluetooth cordless telephone application model that the special interest group of bluetooth is formulated, Bluetooth gateway (GW) links to each other mutual to handle all relevant with external network with external network; Bluetooth voice terminal device (TL) is that wireless user terminal links to each other with Bluetooth gateway by bluetooth wireless links, and in this application model, gateway is main equipment (master), can be that 7 user terminal slave units (slave) provide connection simultaneously.Bluetooth terminal both can have been answered the outside line user of the external network that External Call also can link to each other with gateway by gateway call by Bluetooth gateway.
At present, bluetooth voice terminal device can carry out the bluetooth conversation by blue tooth voice gateway, also can answer and call as a common mobile phone by the mobile network.But present bluetooth voice terminal device generally can only be supported a kind of call mode wherein at one time, and the conversation of two kinds of patterns can not be merged in the conversation, promptly realizes the function of Three-Way Calling.Use to the user brings inconvenience like this.
Summary of the invention
Primary and foremost purpose of the present invention provides a kind of calling maintenance that bluetooth voice terminal device carries out Bluetooth cordless telephone application session and mobile network call office and method of Three-Way Calling supported.The present invention does the control corresponding adjustment by the conversation of the bluetooth between bluetooth voice terminal device pair and the blue tooth voice gateway and utilizes mobile network's calling to keep function to realize that bluetooth conversation and the mutual of mobile network call office freely switch; And be communicated with by the speech channel to bluetooth speech channel and mobile network call office on bluetooth voice terminal device, realize the remote subscriber of bluetooth voice terminal device user, fixed network that blue tooth voice gateway connected and connect three-party talking function between mobile network's the remote subscriber.Wherein, the mobile network can be GSM, CDMA or 3G network etc.
Described method comprises:
(a) on bluetooth voice terminal device, wish to set up a roadbed and use (Cordless Telephony Profile in Bluetooth cordless telephone, be called for short CTP) or bluetooth earphone application (HeadsetProfile, be called for short HSP) or blue tooth vehicular hands free applications (Handsfree Profile, be called for short HFP) and blue tooth voice gateway between the conversation control connection come to carry out the bluetooth conversation with remote subscriber, on this bluetooth voice terminal device, also wish to set up the conversation of one road mobile network simultaneously.Bluetooth voice terminal device can be by utilizing mobile network's calling maintenance technology, and mobile network is conversed to be kept or call recovery, also can utilize with blue tooth voice gateway and communicate conversation maintenance and the call recovery of realizing the bluetooth conversation.Like this, just realized that bluetooth voice terminal device can carry out mobile network conversation and bluetooth conversation simultaneously, and between the two-way conversation, switched.
(b) on bluetooth voice terminal device, carry out simultaneously in bluetooth conversation and the mobile network conversation, can realize the Three-Way Calling between mobile network conversation remote subscriber, bluetooth conversation remote subscriber and this equipment by on bluetooth voice terminal device, being communicated with the speech channel of mobile call and the method for bluetooth speech channel.
(c) the bluetooth method that keeps of conversing is, will realize a simple internal communication mechanism between bluetooth voice terminal device and the gateway, makes bluetooth voice terminal device can notification gateway converse and keeps and call recovery.On this basis, can be connected or keep that bluetooth is conversed control connection and the method that only disconnects the bluetooth speech channel by what disconnect bluetooth conversation control connection between bluetooth voice terminal device and the blue tooth voice gateway and bluetooth speech channel, and under blue tooth voice gateway does not interrupt situation with the conversation of remote subscriber, realize that the conversation of bluetooth conversation keeps.When bluetooth voice terminal device attempts to recover bluetooth when conversation, can keep the method that adopted according to conversation, set up corresponding bluetooth conversation control connection and bluetooth speech channel or only set up the bluetooth speech channel, recover conversation.
(d) for the speech channel of the connection mobile call in the method for between bluetooth conversation and mobile network conversation, setting up Three-Way Calling and the mode of bluetooth speech channel, can pass through hardware mode, the output of the speech channel of bluetooth module and the speech output of mobile communication module are communicated to respectively on the speech output equipment of bluetooth voice terminal device, and the voice input device of bluetooth voice terminal device is linked the input of speech channel of bluetooth module and the speech input of mobile communication module respectively, simultaneously the mobile communication module speech is outputed to the input of bluetooth module speech channel, and the speech of bluetooth module speech channel is outputed to the speech input of mobile communication module.
Owing to can carry out bluetooth conversation and mobile network conversation simultaneously, and can be freely to two-way conversation switch mutually, or two-way conversation coupled together the realization Three-Way Calling, thus make the user very easy to use, and expanded the application of bluetooth voice terminal device.
