The method according to this invention, described step 2 further comprises the steps:
The clock of a, described dominant base interrupts producing and regularly drives dominant base in order to described bus transmission Frame or empty inquiry frame, and carries the sign from the base station that each binding connects in frame in order;
B, described from the base station, only passively described bus is monitored, and behind the packet of reception that be triggered from bus, resolve the bus data bag and judge whether it is to send to oneself according to described sign, if, then packet is extracted and handle, and occupy the bus transmission route, send acknowledgement frame or other packets to bus.
On the other hand, the invention provides a kind of device of in PHS, realizing multi base station binding communication, wherein, comprise at least 2 PHS base stations, it connects with bus mode and communicates, and realizes dynamic base station binding combination by the medium access rules of principal and subordinate's control mode; The base station that is configured to dominant base by clock bus to being configured to from the identical pulse signal of other base station transmits of base station to finish slot synchronization.
According to device of the present invention, it is characterized in that the described bus that is used to communicate by letter is the RS485 bus.
According to device of the present invention, it is characterized in that, described dominant base by clock bus to described respectively from base station transmits 5ms differential clock signal.
According to device of the present invention, it is characterized in that the base station of described each binding is connected on the described bus by the receiving and transmitting signal line of its external serial ports.
According to device of the present invention, it is characterized in that, connect by multicore aviation connector between the described binding base station.
In the present invention, because each binding base station uses bus mode to communicate, thereby make in the binding base station any one or the several base station Shi Buhui that breaks down cause other base station to withdraw from the reliability that bundle status has improved binding.In addition, use bus mode to make the communication efficiency between the base station be improved, thereby can support more base station to bundle.
In the present invention, because the receiving and transmitting signal line of the external serial ports of each binding base station all is connected on the identical bus, in order to make the data transmit-receive of each binding base station on bus not bump or confusion, the present invention has adopted the configuration of each base station basis of medium access rules binding attribute separately of principal and subordinate's control mode to determine that dominant base still is from the base station on the RS485 bus mode.Its principle is: the clock of dominant base interrupts producing and regularly drives dominant base sends Frame or sky in order on bus inquiry frame, carries the sign from the base station that each binding connects in frame in order; Initiatively do not send data from the base station to bus, but do not stop bus is monitored, when on the bus transfer of data being arranged, be interrupted triggering from the base station and obtain data, resolve the bus data bag from the base station, judge according to recipient's sign whether this frame sends to oneself from bus, if send to the frame of oneself, then packet is extracted and handle, and occupy the bus transmission route, send acknowledgement frame or other packets to bus.
In addition, in order to guarantee correct slot synchronization, dominant base by clock bus to all pulse signals from base station output 5ms, from the base station with this frame clock as self.Do not export any clock pulse signal from the base station.
From as can be known above-mentioned, dominant base initiatively sends data to communication bus, and by clock bus to the pulse signal that sends 5ms from the base station; Then only monitor and Clock Extraction from the base station.
