Fig. 5, Fig. 6, Fig. 7 describe is the interaction flow of the call control signalling between Bluetooth phone gateway device 7 and the three kinds of terminal equipments being supported.The software systems of moving in the programmable system that the RAM 1 and the processor 2 of Bluetooth phone gateway device 7 inside constituted are responsible for carrying out controlling the mutual of signaling with various terminal equipments, realize the control of call flow by their.
In three flow processs, the bluetooth communication 3 in the Bluetooth phone gateway device 7 is responsible for the aerial data interaction with bluetooth extension set 12 or bluetooth earphone 9, control channel and speech data below; Data Detection of Bluetooth phone gateway device 7 and external switch and transmission are to finish by the responsible and PSTN switch of phone access module 6 mutual FXO submodule or digital signal processing module 13 or wireless communication module 14 responsible and that the radio communication switch is mutual responsible and that the VoIP SoftSwitch is mutual respectively.
Fig. 5 shows three main flow processs of Bluetooth phone gateway device 7 and the Signalling exchange of bluetooth extension set 5, and wherein the control interface of gateway and bluetooth extension set 5 is the bluetooth protocol repertory subsystem (software) of the software systems moved in the programmable system that is made of RAM 1 and processor 2 and bluetooth communication 3 (hardware) realization:
One, exhalation flow process: the bluetooth extension set beginning (s510) that makes a call; The gateway answering call begins to reply (s511); The bluetooth extension set sends calling number (s512) by the Information signaling, gateway answering call progress (s513); When Bluetooth phone gateway device 7 is learnt called terminal ringing from external switch (can be PSTN switch, VoIP SoftSwitch or radio communication switch) side, send ring-back (s514), gateway is created SCO link (s515) simultaneously; When gateway is learnt called off-hook from external switch side, send offhook message (s516), bluetooth extension set 5 is replied off-hook and is replied (s517), call setup, the exhalation flow process finishes.
Two, incoming call flow process: Bluetooth phone gateway device 7 beginning (s520) that makes a call, if obtained calling number from exchanger side, Bluetooth phone gateway device 7 sends calling numbers (s521, optional); Bluetooth extension set 5 is created bottom and is connected (UNPARK) (s522), and bluetooth extension set 5 sends ring-back (s523), and bluetooth extension set 5 is created SCO link (s524); When bluetooth extension set 5 user's off-hooks, bluetooth extension set 5 sends offhook message (s525), and Bluetooth phone gateway device 7 is replied off-hook and replied (s526), call setup, and the incoming call flow process finishes.
Three, on-hook flow process: when the 5 user's on-hooks of bluetooth extension set, bluetooth extension set 5 sends on-hook message (s530), Bluetooth phone gateway device 7 sends and discharges indication (s531), bluetooth extension set 5 initiates to discharge SCO link (s532), bluetooth extension set 5 sends and discharges finish (s533), Bluetooth phone gateway device 7 is notified external switch user on-hook by above-mentioned with external switch corresponding interface module, and initiatively the on-hook flow process finishes.If Bluetooth phone gateway device 7 occurs need initiatively discharging bluetooth extension set 5 unusually in calling out, discharge flow process directly from step s531.
Fig. 6 shows three main flow processs of the Signalling exchange of gateway and bluetooth earphone 9, and wherein Bluetooth phone gateway device 7 is identical with realization principle and Fig. 5 of the control interface of bluetooth earphone 9:
One, incoming call flow process: outside incoming call, Bluetooth phone gateway device 7 regularly send ring (s610) for bluetooth earphone 9, and be overtime after the time until user's off-hook or t1; Bluetooth earphone 9 user's off-hooks, bluetooth earphone 9 sends off-hook signaling (s611), and Bluetooth phone gateway device 7 is replied OK (s612), and creates SCO link (s613), call setup, the incoming call flow process finishes.
Two, volume control flow: the volume control flow is divided into Bluetooth phone gateway device 7 and 9 two aspects of bluetooth earphone again.During bluetooth earphone 9 change volumes, send the volume rank after Bluetooth phone gateway device 7 changes are notified in Headphone volume control (s620) and microphone volume control (s630) respectively, Bluetooth phone gateway device 7 is all replied OK and is got final product (s621, s631); During Bluetooth phone gateway device 7 control bluetooth earphones 9 change volumes, send Headphone volume control (s640) respectively and get final product with microphone volume control (s650).
Three, on-hook flow process: in the conversation, bluetooth earphone 9 users press on-hook key, and bluetooth earphone 9 sends on-hook signaling (s660), and Bluetooth phone gateway device 7 is replied OK (s661), and discharge SCO link (s662), and the on-hook flow process finishes.
Fig. 7 shows three main flow processs of the Signalling exchange of gateway and FXS extension set 12, and wherein the control interface of gateway and FXS extension set 12 is to be realized by the FXS subelement of phone access module 6 and the FXS ring detection sub-unit of ring detecting circuit 11:
One, exhalation flow process is divided into following sub-process again:
A) first is to start the sub-process that collects the digits: FXS extension set 12 user's off-hooks (s710); The FXS ring detection sub-unit of ring detecting circuit 11 detects the FXS off-hook, report the software systems of Bluetooth phone gateway device 7, the software systems of Bluetooth phone gateway device 7 begin to start DTMF and collect the digits (s711), simultaneously issue starting impulse collect the digits (s712) to the FXS of phone access module 6 subelement;
B) second is the DTMF sub-process that collects the digits: dial when the user takes the DTMF mode, FXS extension set 12 reports (s713) DTMF number, 7 stop pulses of Bluetooth phone gateway device collect the digits (s714); Think that until Bluetooth phone gateway device 7 number mates, send and to stop DTMF collecting the digits (s715);
C) the 3rd is the pulse telephone number receiving sub-process: when the user takes pulse mode dialing, FXS extension set 12 reports pulse number (s716), and 7 of Bluetooth phone gateway devices stop DTMF collecting the digits (s717); Think that until Bluetooth phone gateway device 7 number mates, send stop pulse collect the digits (s718).Second and the 3rd sub-process do not coexist, and when second sub-process begins, then can not enter the 3rd sub-process, and vice versa;
D) optional flow process: learn called terminal ringing when Bluetooth phone gateway device 7 from exchanger side, FXS extension set 12 is put ring-back tone (s719).When Bluetooth phone gateway device 7 is conversed with PSTN, there is not this step.
So far call setup, the exhalation flow process finishes.If the other side's off-hook of calling out, this moment, voice passed through (In Band) transmission in the band, and there has not been Signalling exchange in Bluetooth phone gateway device 7 with FXS extension set 12.Annotate: this embodiment is a DTMF/ pulse telephone number receiving self adaptation.
