5. conversation initiation command.Set up conversation when host computer and connect, begin conversation, can send this order of slave computer, indication slave computer conversation beginning.
6. end of conversation order.When the host computer end of conversation, discharge conversation and connect, can send this order of slave computer, indication slave computer end of conversation.
7. access failure order.Answer or call when host computer, fail to set up conversation and connect, can send this order of slave computer, this takes turns the phone access failure indication slave computer.
8. incoming call is by ath command.When host computer has incoming call, when the third party is initiatively hung up, can send this order of slave computer, indication slave computer incoming call is hung up.
See also Fig. 3 again to shown in Figure 7, it sends process of commands for slave computer to host computer, comprising:
1. when the host computer serial ports had data, host computer was intercepted and captured this data, judged that these data are the SLIC order, was not then to change other handling processes over to; Be then to handle this order.
2. when judging that this order is the order of slave computer off-hook, enter slave computer off-hook module.
3. when judging that this order is slave computer on-hook order, enter slave computer on-hook module.
4. when judging that this order is slave computer dialing order, enter the slave computer dial module.
5. when judging that this order is slave computer transmission DTMF data, enter slave computer and send the DTMF data module.
For slave computer off-hook resume module flow process, specific as follows:
When the slave computer off-hook, if host computer has incoming call at this moment, then slave computer can be answered this incoming call; If no, then put the host computer holding state.
For slave computer on-hook resume module flow process, specific as follows:
When the slave computer on-hook,, judge further then whether host computer locates the IDLE interface, is then to cancel this presence if host computer has off-hook or hands-free; Not then to locate to dial interface etc., so do not handle;
If host computer does not have off-hook or hands-free, judge further then whether host computer locates talking state, is then to cancel current talking, is not then to cancel presence.
For slave computer dial module handling process, specific as follows:
When slave computer dials, host computer will be received dial data twice.Judge at first whether this dial data is correct, otherwise return immediately; Be the beginning of then dialling, finish the initialization of the required condition of dialing.Judging that then these data are data retransmission, is then to abandon this data retransmission, is not then to handle this dial data, and as showing dialing interface, FD finished dialing is dialed etc.
Send DTMF data module handling process for slave computer, specific as follows:
When slave computer sent the DTMF data, host computer was handled this DTMF data, realized the DTMF function.
Software for slave computer is realized, sees also Fig. 8 to shown in Figure 10.Wherein A represents the wireless business phone, and B represents common phone.
One, Lai Dian processing procedure is as follows:
1.A the situation of answering---after A receives incoming telephone signal, send RING or CLIP to B " telephone number " signal, B begins ring, sends up to A and answers signal B and stop ring and enter talking state.A opens voice channel, and at this time the B off-hook also can be heard conversation sound, B and can replace A to converse.
2.B the situation of answering---B sends DNHOOKON, and A opens voice channel.A stops ring, and B enters talking state.
3.A hang up, A closes the tinkle of bells, A sends UPHANGUP, and B turn-offs jingle bell.
The course of work is as follows:
Under standby mode, whether cyclic query has incoming information, up to incoming call is arranged.Wireless business Advise By Wire single-chip microcomputer has phone to arrive, and telephone number is given, and single-chip microcomputer goes to control the caller identification of common phone again, opens the electric bell sound.If the wireless business phone is hung up incoming call, wireless business Advise By Wire single-chip microcomputer turns off to come the electric bell sound.If answer, judgement is that wireless business telephone receiving or common phone are answered, and notifies the other side's change state to enter into talking state then.
Two, the processing procedure of dialing is as follows:
1.A dial, A sends the control that UPHOOKON has dialogue machine, B enters talking state after receiving the CONNECTON signal.
2.B dial, B sends the control that DNHOOKON has dialogue machine, A realizes that real number sends, and A connects and sends CONNECTON under the situation about finishing and open voice channel receiving link, and B enters talking state.At this moment the A off-hook can be heard the conversation of B.
3. the other side is hung up, and A sends OHANGUP, and B directly enters the IDLE state from dialing state.
The course of work is as follows:
Whether holding state judges off-hook, if do not have, update mode always then is up to off-hook is arranged.Judgement is wireless business phone off-hook or common phone off-hook, notifies the other side to enter off hook state by single-chip microcomputer then.Waiting for dials finishes, and enters the dialing wait state, judges that changing communication process is hung up or be connected, if the other side answers, wireless business Advise By Wire common phone enters talking state.If hung up, then judge the side of hanging up, if hanging up the telephone, the wireless business phone judges whether common phone is in hook state earlier, if hook state non-processor then, if off hook state does not then cut off path up to the appearance of hanging up that has next time.If common phone is hung up, single-chip microcomputer earlier judges whether the wireless business phone is in the state of hanging up, if hang up state then common phone hang up, if off hook state, the state of record wireless business phone was hung up generation when then common phone was hung up up to next time.If the other side is hung up, the notice common phone was hung up and is entered holding state when then the wireless business phone was hung up.
Three, the processing procedure of hanging up under the on-state is as follows:
1. the other side is hung up, and A sends CONNECTOFF after receiving the signal that link finishes, and B enters the IDLE state from talking state.
2.A hang up, A sends UPHOOKOFF, if B not off-hook enter the IDLE state from talking state, A closes voice channel.If B off-hook, A are not done any operation up to receiving that DNHOOKOFF just closes voice channel.If B is the A on-hook under the situation of off-hook, should keep conversation, consider that the telephone user changes the situation of extension set, what consider now is to keep talking state before in the end a telephone user hangs up, the extension set of family also should be this situation now.
3.B hang up, B enters the IDLE state, B sends DNHOOKOFF.If A is off-hook not, then turn-off voice channel.If the A off-hook is not then done any operation till A is initiatively hung up.All be based upon A about the operation of Three-Way Calling and set up operation such as Three-Way Calling and just can finish, common phone does not have that function, and the common extension set that uses of family does not have three-party talking function yet now, so common phone can not be controlled Three-Way Calling.If carry out the support that Three-Way Calling must obtain fixed CDMA WLL, and on fixed line, do corresponding interpolation deletion action.
The course of work is as follows:
Whether talking state judges hangs up, if do not have, then cycle criterion talking state is up to there being a side to hang up the telephone.Judgement is which side is hung up the telephone, if the other side hangs up the telephone, the notice common phone was hung up and entered holding state when then the wireless business phone was hung up.Then judge whether on-hook of common phone if the wireless business phone is hung up,,, take place up to hanging up once more if off hook state does not then turn-off actual path if hook state then finishes., common phone judges whether the wireless business phone is in hook state if hanging up, if hook state then finishes, if the off hook state state of common phone on-hook time record wireless business phone then judges whether hanging up of a new round then.
