In the present invention, the communication means of radio station network is such, and first data channel in the binary channels radio station in described first network and each sub-radio station adopt GMSK or BPSK modulation system to modulate signal, and carry out signal transmission according to time division multiplexing mode; Second data channel in the binary channels radio station in described second network and each sub-radio station adopt GMSK or BPSK modulation system to modulate signal, and carry out signal transmission according to time division multiplexing mode; Between the inner each member of first network, adopt the radio wave of the frequency range different from second network to carry out communication.In binary channels radio station, one of them data channel is in the time of transmitting data state, and another data channel is in disabled status.
Now set forth time-division multiplex communication method as an example of first network example:
First, will be divided into unit when some the time, when each, unit comprises that time synchronized time slot, sub-transceiver accesses to network application time slot, binary channels transceiver accesses to network reply time slot, binary channels radio station data slot and sub-radio station data slot;
Wherein, when time synchronized time slot is arranged in before other time slots of unit.The first data channel in synchronization slot in binary channels radio station is sent synchronizing signal, and the sub-radio station in first network is obtained synchronously by the synchronizing signal of obtaining in synchronization slot.
After sub-transceiver accesses to network application time slot is positioned at synchronization slot, in sub-transceiver accesses to network application time slot, each sub-radio station sends to the first passage in binary channels radio station the request of networking according to contention mode.So-called contention mode refers to, when same, in the sub-transceiver accesses to network application time slot of unit, can only there is a sub-radio station to send the request of networking, that is to say each sub-radio station can any one time unit sub-transceiver accesses to network application time slot in send network request, if but have many estrades radio station to send the request of networking in the sub-transceiver accesses to network application time slot in same unit for the moment, there is networking request collision, the networking request that send simultaneously in many estrades radio station is in this case invalid, and unit sends the application that networks can to wait for lower a period of time.
Binary channels transceiver accesses to network is replied after time slot is positioned at sub-transceiver accesses to network application time slot, reply in time slot at binary channels transceiver accesses to network, the first passage in binary channels radio station is made to the sub-radio station of sending the application that networks in this time unit and is replied and be that it specifies sub-radio station data slot.
In the data slot of binary channels radio station, the first passage in binary channels radio station sends data with the forms of broadcasting, and each sub-radio station in first network receives the data that bilateral passage radio station first passage sends.
Sub-radio station data slot quantity can be multiple, and a sub-radio station data slot is monopolized in the sub-radio station of each in first network.For example n n the sub-radio station data slot that sub-radio station is monopolized, n is positive integer, and n sub-radio station sends data, and first data channel in binary channels radio station receives data.
When each, in unit, can also arrange and can distribute time slot; In the time having new sub-radio station application to add first network, first data channel in binary channels radio station can be divided new sub-radio station data slot time slot and is used in reference to the sub-radio station of tasking new networking from being distributed.
In order to realize voice communication between radio station in network, time speech time slot can also be set in unit.In speech time slot, in first network, voice communication is carried out according to contention mode in binary channels radio station passage, each sub-radio station.That is to say in the speech time slot of unit when same, can only have a radio station to send voice signal, other radio station can only received speech signal, if having multiple radio station to send voice signal in the speech time slot with unit for the moment, there is conflict, cannot realize voice communication.
A specific embodiment of time slot allocation in unit while being of the present invention as the time slot splitting scheme of Fig. 3 demonstration.In one network, all radio station are all with reference to a standard time; Different sub-radio station time slot (timeslice) busy channel in accordance with regulations; Its time slot is reused by each time unit in the cycle in sub-radio station.
The splitting scheme of this time slot is to have formulated having considered channel speed, user networking quantity, multi-channel transmit blackberry lily and disturb etc. after the factor of aspect, and the better reliability of supported data transmission can meet again the demand of voice data simultaneous interpretation.When above-mentioned, in unit, the distribution of time slot is equally applicable to second network.
In Fig. 4, be binary channels radio station the first data channel and the second data channel transceiving data time slot allocation embodiment.The splitting scheme of this time slot, time synchronized time slot, sub-transceiver accesses to network application time slot, binary channels transceiver accesses to network are replied the sequencing of time slot and are determined, and binary channels radio station data slot, sub-radio station data slot, speech time slot and can distribute the order of time slot to set arbitrarily, as long as binary channels radio station data slot, sub-radio station data slot, speech time slot and can distribute time slot to be positioned at after binary channels transceiver accesses to network replys time slot in the order of Shi Yuanzhong.In actual applications, between above-mentioned each time slot of Shi Yuanzhong, can also be provided with reserved time slot, in the reserved time slot moment, the radio station in network does not send information and does not receive signal yet.Can accomplish to work as one of them passage transmitting data of binary channels radio station by arranging of reserved time slot is another passage forbidding.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
