Multi-holder cordless telephone set style of work principle is: adopting channel spacing is the narrow-band FM radiotechnics of 25kHz, operating frequency is whole channels of each national home cordless phone frequency range, each channel is made up of FH and two frequencies of FL, one of them is a upstream frequency, and another is a downstream frequency; At first select idle channels during the handset call outside line, then on this channel by transmitting radio signaling all bases in the access means successively, if receive the receipt signaling of a certain base, then open mobile phone, set up the communication of the local telephone that mobile phone is connected with this base; The time of the every pedestal machine of mobile phone access is the finite time of setting, if surpass the receipt that setting-up time is not received base yet, then this base may just hurry or surpass effective communication distance or break down; During the outside line incoming call, if base is in direct dialing extension set pattern, then outside line can be dialed directly extension, then launches common ring signaling to the common ring mobile phone of this base and makes the ring simultaneously of these mobile phones if base is in common Ring Mode; During the call extension extension set, need only the caller extension set dial called extension number and get final product; Can carry out full-duplex communication mutually in order to make between whole extension sets, base and mobile phone all adopt and change the channel full duplex communication means, promptly the base in the device is under the normal communication condition and under the stand-by state, receive frequency is FH, and tranmitting frequency is FL, when base is called out base, the receive frequency of caller base becomes FL by FH, tranmitting frequency becomes FH by FL, so the caller base is just corresponding mutually with the sending and receiving frequency of called base, thereby has realized the full-duplex communication between the base; Mobile phone in device receive frequency under the normal communication condition is FL, and tranmitting frequency is FH, with the sending and receiving frequency of base corresponding relation is arranged; When the handset call mobile phone, the frequency of accepting of caller mobile phone becomes FH by FL, and tranmitting frequency becomes FL by FH, so the caller mobile phone is just corresponding mutually with the sending and receiving frequency of called mobile phone, thereby has realized the full-duplex communication between the mobile phone; The realization of every function of device is to finish by the software in base and the mobile phone microcontroller, shown in Fig. 4 (base Control Software programming flowchart) and Fig. 5 (mobile phone Control Software programming flowchart): base, mobile phone all is in the marquis's state of keeping at ordinary times, during the outside line incoming call, bell signal is arranged on the telephone wire and detected by base, at this moment, base is judged own still " common ring " pattern of " direct dialing extension set " pattern that is made as by the user, and selection idle channels, then, if " common ring " pattern is emission immediately " common ring " signaling then, if " direct dialing extension set " pattern waits for that then receiving outside line dials next extension, in case receive that extension is promptly to specifying extension set emission ring signaling; At first select idle channels during the handset call outside line, on this channel, launch " handset call outside line " signaling to each base successively then, in case receive the receipt signaling of certain base then show that this base is idle and with the communication link connection of mobile phone and this outside line, at this moment, mobile phone will be opened audio frequency sending and receiving path automatically, establish a communications link; When base was called out base, the caller base was selected idle channels earlier, exchanges the sending and receiving frequency again, and emission " base calling base " signaling is then waited for the off-hook signaling that receives the other side after receiving the receipt signaling; During the base calling handset, base is selected earlier idle channels, and emission " base is exhaled mobile phone " signaling is again waited for the off-hook signaling that receives mobile phone after receiving the receipt signaling; During the handset call mobile phone, the caller mobile phone is selected earlier idle channels, exchanges the sending and receiving frequency again, and emission " handset call mobile phone " signaling is then waited for the off-hook signaling that receives the other side after receiving the receipt signaling; During the handset call base, mobile phone is selected earlier idle channels, and emission " mobile phone is exhaled base " signaling is again waited for the off-hook signaling that receives base after receiving the receipt signaling.Mobile phone or base are received machine ringing after the ring signaling, during the ring if off-hook is then sent out the off-hook signaling to the calling party, enter talking state after receiving calling party's receipt signaling, if do not receive calling party's receipt signaling in the limiting time, then think to exceed effective communication distance, therefore report to the police; In the software, base and mobile phone can be equal to as the extension set of a certain base to be treated, so the form of " base calling base " signaling, " handset call mobile phone " signaling, " base calling handset " signaling, four kinds of signalings of " handset call base " signaling is identical, just caller is different with called extension.
