Do not obtain answering if call out within the predetermined time, (line is droped) then goes offline.
Link sends the radio link continuous tone in the voiced band scope when connect going up, so whether and state the existence that system comes monitoring wireless current source road with sensing continuous tone or other continuous shows signal.This continuous tone can be separated it with a notch filter.
If radio link no longer exists, and the caller does not have on-hook (hang up), and then system keeps the connection of calling line.Simultaneously, the telephone line that is come out by cell phone is gone offline, and then goes to instruct cell phone to remove to rebuild link.Because the state of travelling carriage 1 is confirmed in advance, so link can preferentially rebulid.Rebuilding the key road is transparent (transparent) to the cell phone user.
Have only when caller's on-hook or when the scheduled time (for example 10 seconds) and just no longer get in touch this calling after requiring when still reactionless later or from the dialing that repeatedly repeats of paging channel.
For carrying out by the outside calling of travelling carriage 1, beep-pager 4 is added to a prefix (prefix) on the number of being dialled.This makes calls out by main control centre and by (be routed) along separate routes, and this control centre then maintains communication link between travelling carriage and the receiving terminal with the same way as to the calling that enters.
Another substitute mode is not to make amendment on the existing system basis removing to control cell phone with the beep-pager co-operation, but sets up a complete new system and a cell phone co-operation and strengthen the ability of base station.Base station is provided with microprocessor controller and RF receiver (as beep-pager), in order to receive the instruction from control channel.With such system, (cross-Cell) link of cross unit formula can more effectively be rebuild.
Each base station all has the identification number of himself, and stores the form that comprises adjacent base station identification number.These identification numbers can constantly be updated through beep-pager.
Between caller and the recipient get in touch foundation after, the state of travelling carriage 1 is delivered to main control centre 2 together with the identification number of base station.On control channel, broadcast the identification number of travelling carriage and base station.Other base stations that receive this transmit will contrast the form of its storage and check this identification number, in case should broadcast identification number corresponding to an adjacent base station time, receiving platform just carries out the reconstruction of a preferential cross unit link.
Transmission or transfer that paging signal or Radio Link can utilize some relay stations, cable or fluting cable (leaky cable) to pass through the area are sent signal into a main push-towing rope line, or these transfer approachs are combined are used.
In a word, the present invention relates to a kind of like this system, this system has done transformation to cordless telephone (for example CT2), makes it to combine with beep-pager, just can receive the calling that enters, and carries out the switching between the cross unit.Beep-pager connects on the telephone set, and comes this telephone set of working control according to the information from main control centre that beep-pager is received, the ans back of being fixed by control centre with automatic calling is so travelling carriage is just got in touch with through control centre and caller.
