Step S63, every the first preset time, determine the negotiation signal of received opposite end rate.
During rate consulation, it is continually changing for carrying out negotiation signal transmitted by the both ends of rate consulation, so the rate of primary received negotiation signal is redefined every the first preset time, to trigger the negotiation of a receiving end rate.
Step S64, determine received negotiation signal rate it is whether consistent with the set receiving velocity Rxv of intelligent terminal 108, if inconsistent, then explanation is without in negotiation, then follow the steps S66, if consistent, illustrate the rate that the intelligent port 108 supports Peer-Port to send, then follow the steps S65.
Step S65, judges whether the current receiving velocity is more than or equal to the currently transmitted rate of set intelligent port 108, if more than or be equal to, then illustrate currently negotiated rate,
The i.e. described current receiving velocity is the maximum rate that both ends are all supported, then illustrates that the intelligent port 108 on the rate consulation of opposite end, thens follow the steps S67, using the current receiving velocity as the negotiated speed of intelligent port and opposite end.If being less than, illustrate that intelligent port 108 supports the transmission rate of opposite end, still, which may not be that the maximum value for the rate that intelligent port and Peer-Port are supported jointly thens follow the steps S66 so also to continue to negotiate.
Step S66, judges whether the timing of the receiving velocity timer is greater than the second preset time.
Second preset time is the pre-set duration for carrying out receiving velocity negotiation, second preset time is related with the number of rate in the first preset time and receiving velocity list, first preset time is the second preset time multiplied by the number of the rate in receiving velocity list, it can guarantee in the second preset time in this way, all rates in the receiving velocity list were all negotiated once.When the timing of the receiving velocity timer is not more than second preset time, S68 is thened follow the steps, when the timing of the receiving velocity timer is greater than second preset time, thens follow the steps S69.
Step S68, update current receiving velocity Rxv, updated current receiving velocity is next rate Rxnext of the current receiving velocity Rxv before updating in receiving velocity list, to prepare to hold consultation to next rate Rxnext, next rate Rxnext can also be recorded as an interim receiving velocity, use when being negotiated with facilitating followed by transmission rate, then return step S63.
Step S69 sets equal with current transmission rate Txv for current receiving velocity Rxv.
Step S70 determines whether the rate of received negotiation signal is consistent with current receiving velocity Rxv, if unanimously, in the currently transmitted rate Txv negotiation for illustrating received negotiation signal rate and intelligent port 108, thening follow the steps S67；If inconsistent, S71 is thened follow the steps.
Execute step S69 and S70, will current receiving velocity Rxv be set as with after current transmission rate Txv, once negotiated with the rate of received negotiation signal again, if in negotiation, it does not need then to execute the currently transmitted rate of subsequent adjustment and continue the process negotiated, so as to quickly determine negotiated speed.
Step S71, when judging whether transmission rate timer institute timing duration is preset more than third
It is long.The third preset duration is used to control the negotiation duration of transmission rate, the third preset duration is related with the number of transmission rate in second preset duration and the transmission rate list, the i.e. described third preset duration is equal to second preset duration multiplied by the number of the transmission rate in the transmission rate list, it can guarantee within the period 3 in this way, each transmission rate in the transmission rate list was negotiated once.If transmission rate timer institute's timing duration is more than third preset duration, S72 is thened follow the steps, if transmission rate timer institute timing duration is not above third preset duration, thens follow the steps 73.
Step 72, update currently transmitted rate Txv, updated currently transmitted rate Txv is next rate Txnext of the currently transmitted rate before updating in transmission rate list, and it is the interim receiving velocity recorded in step 68 that current receiving velocity, which is arranged, then return step S63.I.e. after currently transmitted rate Txv update, a wheel negotiation is carried out again to the receiving velocity received in rate list.Set the interim receiving velocity Rxmem for current receiving velocity Rxv, can currently transmitted rate Txv update after, from the interim receiving velocity Rxmem for recording receiving velocity when receiving velocity timer terminates timing negotiate.
