Forwarding to after next call channel, MPTY is supervised at sliceO againListen, then select suitable slice to continue to send calling PDU, await a response.
If what receive is Commence order, then adjusts to the transmission channel that callee specifies and start communication.
If what receive is Abort order, then ends this link setup and attempt, get back to scanning mode.
Response state: when being in the website of scanning mode receives calling, it can enter response state immediately. AsThe calling PDU that fruit receives does not have mistake, and it can send it back and answer at next slot:
Accept this link setup request if be reluctant, Abort order will be sent out.
Accept this link setup request if be ready, but not yet find a suitable transmission channel, Continue lifeOrder will be sent out.
Accept this link setup request if be ready, and find a suitable transmission channel, Commence orderWill be sent out, wherein comprise the information of specified transmission channel;
Data send state: when receiving the remote interrupt of the data transmission state from HF networking control device,I.e. the 5th timeslice, data transmitting time sheet. If this timeslice is preengage by data service, then electricityAfter platform transceiver is modulated in the Traffic Channel of corresponding reservation, send or receive data service; If competingStrive this timeslice for transmission control frame, radio station transceiver is modulated in the Traffic Channel of corresponding reservationRear transmission control frame, otherwise receive data or do not do anything;
Data re-transmission state: when receiving data from HF networking control device module sends in state long-rangeWhen disconnected, i.e. the 6th timeslice, retransmits timeslice. This time slot is used for controlling the weight that needs the control frame retransmittingBiography process. If certain control frame number of retransmissions reaches maximum and is not still successfully received, by this frame from queueDelete. Otherwise, be less than maximum although be not successfully received number of retransmissions, then corresponding control frame putPut queue tail and wait for re-transmission next time.

Simultaneous call state: in receiving simultaneous call state from HF networking control device module long-rangeWhen disconnected, i.e. the 1st timeslice, simultaneous call timeslice, this stage is divided two states: exploration state andResponse state:
Exploration state: the website of preparing link setup enters exploration state and does for sending calling PDU (Call_PDU)Prepare, MPTY calculates the frequency that callee is scanned, if in the interior competition of timeslice 0 to this time slot, thenEnter the simultaneous call stage, this one of them timeslice of Stochastic choice then on calling channel with Probability pMake a call, if shaken hands in calling procedure successfully, then record corresponding Traffic Channel, then unsuccessfulDo not do anything:
If what receive is Continue order, MPTY is in the residue of 5.4 seconds residence times of this channelIn time, any action no longer will be done, forwarding to after next call channel, MPTY is supervised at slice0 againListen, then select suitable slice to continue to send calling PDU, await a response,
If what receive is Commence order, then adjusts to the transmission channel that callee specifies and start communication;
If what receive is Abort order, then ends this link setup and attempt, get back to scanning mode;
Response state: when being in the website of scanning mode receives calling, it can enter response state immediately, asThe calling PDU that fruit receives does not have mistake, and it can send it back and answer at next slot:
Accept this link setup request if be reluctant, Abort order will be sent out;
Accept this link setup request if be ready, but not yet find a suitable transmission channel, Continue lifeOrder will be sent out;
Accept this link setup request if be ready, and found a suitable transmission channel, Commence lifeOrder will be sent out, and wherein comprises the information of specified transmission channel;
Data send state: when receiving data from HF networking control device module sends in state long-rangeWhen disconnected, i.e. the 5th timeslice, data transmitting time sheet, if this timeslice is preengage by data service,After then radio station transceiver is modulated in the Traffic Channel of corresponding reservation, send or receive data service; AsFruit competition is to this timeslice for transmission control frame, and radio station transceiver is modulated to the business letter of corresponding reservationTransmission control frame after on road, otherwise receive data or do not do anything;
Data re-transmission state: when receiving data from HF networking control device module sends in state long-rangeWhen disconnected, i.e. the 6th timeslice, retransmits timeslice, and this time slot is used for controlling the weight that needs the control frame retransmittingBiography process, is not still successfully received if certain control frame number of retransmissions reaches maximum, by this frame from queueDelete, otherwise, be less than maximum although be not successfully received number of retransmissions, then corresponding control frame putPut queue tail and wait for re-transmission next time.
