Description
Technical field
The invention belongs to wireless communication field more particularly to TETRA special digital Group communication devices.
Background technology
TETRA is European Communication Standard association (ETSI) to meet the specialized department of European Countries to proprietary wireless communication
Demand and the wireless communication system of open standard that designs, be widely used in Europe.China will be also in the end of the year 2000
Establish one of four standards that TETRA is Chinese Digital cluster communication recommendation type.TETRA standards are mesh compared to other standards
Most careful, opening is best, technology is most advanced, participation manufacturer the is most digital cluster system of preceding formulation.
TETRA agreements have largely used for reference the concept of GSM, using 4 time slot time division multiple access (TDMA) technologies, a 25KHz band
Wide carrier wave supports 4 time-derived channels.TETRA channels are physically divided into：Main control channel and Traffic Channel, TETRA main carriers
The 1st time slot be used as Main control channel, TETRA Main control channels are the signalling paths of TETRA systems, and main carrier it is non-1st when
All channels of the channel of gap and non-main carrier are then Traffic Channels, for carrying TETRA business (including speech business sum number
According to business) data, the as media channel of TETRA, but can also be used as signalling path use.
The logic channel that TETRA standards define has:AACH、BSCH、TCH2.4、TCH/4.8、TCH/7.2、SCH/HD、
The logic channels such as BNCH, STCH, SCH/HU, SCH/F.
TETRA standards, which define physical channel, has 3 kinds of operating modes i.e.：Signaling mode, business model and unallocated pattern,
There was only one mode, i.e. signaling mode for Main control channel, and for Traffic Channel, according to different 3 kinds of patterns of type of service
It is likely to occur.
Used logic channel is what different and different logic channels used to Traffic Channel in different modes
Channel coding method is also different (see Fig. 1).If the incorrect or configuration opportunity of channelling mode configuration incorrect can influence
Arrive, reciever is correctly decoded reception to message, therefore, the operating mode of correct configuration service channel become one it is crucial
Problem.
Invention content
The technical problems to be solved by the invention are：Based on TETRA signaling models, the signaling occurred in advance is prejudged,
Traffic Channel is configured by what collocation channel automated, the signalings of traditional TETRA call control layers need by
CMCE, MLE, the LLC layer of TETRA can be only achieved UMAC layers, and TETRA call control layers are directly sent to UMAC layers in the present invention
Configuration signal may insure that configuration signal can quickly be sent to UMAC in this way, so that it is guaranteed that the height of TETRA channelling modes switching
It is fast effective, greatly improve the working performance of TETRA systems.
In order to solve the above-mentioned technical problem, the present invention is achieved through the following technical solutions, and one kind is based on TETRA signaling moulds

Rapid 5；
Step 3：Whether the signaling message for judging Main control channel according to signaling message types can generate traffic channel assignments, such as
Fruit can generate traffic channel assignments, then enter step 4, otherwise terminate flow；
Step 4：The call control layer of TETRA systems is matched by directly reaching the channel transmission of the UMAC layers of TETRA systems
Confidence enables, which is business model traffic channel configuration, then terminates flow；
Step 5：Whether can generate the switching of operating mode, if work will not be generated if judging the signaling message of Traffic Channel
The switching of pattern, then terminate flow；If the switching of operating mode can be generated, 6 are entered step；
Step 6：According to the type for the operating mode that Traffic Channel is switched to, the call control layer of TETRA systems passes through
The channel transmission configuration signal of the UMAC layers of TETRA systems is directly reached, the configuration signal is traffic channel configuration into being switched
Into operating mode, then terminate flow.
Wherein, the TETRA systems include channel device, TETRA base station controllers, switching centre, the wired scheduling of TETRA
Platform and TETRA gateways.
Wherein, the TETRA terminals include TETRA hand-held stations, TETRA Vehicle mounted stations or TETRA fixed stations.

Body is：The process of the call control layer of TETRA systems is directly sent by udp protocol to the process of the UMAC layers of TETRA systems
Configuration signal.
Wherein, configuration signal is specially into the operating mode being switched to traffic channel configuration in the step 6：If work
Operation mode is switched to business model, then traffic channel configuration into business model；If operating mode is switched to signaling mode,
Then traffic channel configuration into signaling mode；If operating mode is switched to unallocated pattern, traffic channel configuration Cheng Wei
Allocation model.
Using advantageous effect caused by above-mentioned technical proposal：
Model of the method for the present invention based on TETRA signalings, TETRA signaling models are with reference to TETRA standard documents
《ETSI EN30039202》Described signaling process.Content the present invention is based on signaling quickly can timely prejudge business
The operating mode of channel, and by the special quick configurating channel pattern of collocation channel, and TETRA logic channels can be passed through
AACH correctly indicates current channelling mode, ensures that the correct effective interaction of TETRA space interface signalings.

The method of the invention is described in further detail in transmitting voice service with reference to Fig. 3.
1. when TETRA systems receive U-SETUP (setup requests) signaling message, system response D-SETUP message (bands
Traffic channel assignments), based on TETRA signaling models, the system that can prejudge will use Traffic Channel and Traffic Channel acquiescence mould
Formula is business model, thus can by special collocation channel traffic channel configuration be business model (media channel).
2. TETRA systems receive U-TX DEMAND signalings, system response D-TX GTANTED message (award by business transmission
Power), based on TETRA signaling models, can prejudge system will use Traffic Channel, the Traffic Channel if former channel is signaling mode
Business model will be switched to from signaling mode, can by special collocation channel traffic channel configuration be business model；If
For business model, then operating mode remains unchanged (media channel) former channel.
3. TETRA systems receive U-TX CEASED signalings, system responds D-TX CEASED message (business transmission stops),
Based on TETRA signaling models, can prejudge system will use signaling channel, and Traffic Channel will be from if former channel is business model
Business model is switched to signaling mode, can by special collocation channel traffic channel configuration be signaling mode；If original letter
For signaling mode, then operating mode remains unchanged (signalling path) in road.
4. TETRA systems receive U-DISCONNECT signalings, system responds D-RELEASE message (business transmission stops),
Based on TETRA signaling models, the system that can prejudge will discharge channel, and Traffic Channel will be released and not use, therefore can be with
By special collocation channel traffic channel configuration be unallocated pattern (channel does not use).
In conclusion these are only the preferred application example of the present invention, it is not intended to limit the scope of the present invention.It is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the guarantor of the present invention
