In the time that described response message is the refusal access response message of described wireless access device feedback, described endEnd finishes the access process to described wireless access device.
Preferably, in step S3, specifically comprise the steps:
After terminal connects, monitor the data traffic of described terminal; According to default power consumption control planSlightly, determine the radio-frequency power that described data traffic is corresponding; By the current radio-frequency power of described terminal, be adjusted intoThe radio-frequency power that described data traffic is corresponding, to control the power consumption of described terminal; The data traffic of described terminalComprise: upstream data flow and downlink data flow; The radio-frequency power of described terminal comprises: transmitting power andReceived power. The kind of data traffic includes but not limited to: video data flow and voice data flow, numberComprise at least one in size and the speed of data traffic according to flow. The present embodiment preferably, the number of terminalBe video data flow according to flow.
Preferably, described default described power consumption control strategy, comprising: described terminal comprises multiple transmitting powersWith multiple received powers; For each transmitting power of described terminal arrange corresponding upstream data range of flow andDownlink data range of flow; For each received power of described terminal arranges corresponding upstream data range of flowWith downlink data range of flow. Concrete, can be according to the difference of data service, specified data business upperRow data range of flow and downlink data range of flow; Can also, according to the difference of data service, determine terminalWhile carrying out this data service, most suitable transmitting power and/or received power, this most suitable transmitting power and/ or received power can reduce power consumption or make not phenomenal growth of power consumption; By the upper line number of a certain data serviceAccording to the transmitting power of range of flow and corresponding this data service of downlink data range of flow, and/or by a certain dataCorresponding the connecing of this data service of the upstream data range of flow of business and downlink data range of flow penetrated power. AsFruit data service, to transmitting power or not requirement of received power, can not arrange the transmitting that this does not requireThe upstream data range of flow that power or received power are corresponding and downlink data range of flow.
For example: when terminal is idle, in the time that power consumption control strategy is set, terminal upstream data range of flow 0～5kbps, downlink data range of flow 0～5kbps, corresponding transmitting power is that 15dB, received power are17dB. And for example: terminal downloads video data, the feature of foradownloaded video data are downlink data flows much larger thanUpstream data flow, as: downlink data flow is 200k/s, and upstream data flow is 5kbps, is like thisThe power consumption of control terminal, can not increase considerably it, can keep the received power of terminal constant, reduceThe transmitting power of terminal. Terminal downlink data range of flow 150～300kbps, upstream data range of flow0～5kbps, corresponding transmitting power is that 7dB, received power are 17dB.
Preferably, determine the radio-frequency power that described data traffic is corresponding, comprising: according to default power consumption controlStrategy, determines transmitting power that described upstream data flow and downlink data flow are corresponding and described upData traffic and received power corresponding to downlink data flow; It is described by the current radio-frequency power of described terminal,Be adjusted into radio-frequency power corresponding to described data traffic, comprise: by transmitting power current described terminal and connecingReceive power, be adjusted into respectively transmitting power and reception that described upstream data flow and downlink data flow are correspondingPower.
Preferably, in step S4, by the current transmit power of terminal and received power, be adjusted into terminalTransmitting power and received power that upstream data flow and downlink data flow are corresponding. By adjusting sending out of terminalPenetrate power and received power, can reduce power consumption, or make the not obvious increase of power consumption, save the electric weight of terminal,Extend the cruising time of terminal.
By monitoring, obtain terminal downlink data range of flow 200kbps, upstream data range of flow3kbps, according to power consumption control strategy, determines downlink data range of flow 200kbps, upstreamThe transmitting power that weight range 3kbps is corresponding is that 7dB, received power are 17dB, and then terminal can be worked asIt is that 7dB, received power are 17dB that front radio-frequency power is adjusted into transmitting power. And then, launch by reductionThe mode of power, the power consumption of reduction terminal.
Certainly, if the current transmit power of terminal, received power, and determine according to power consumption control strategyTransmitting power, received power identical, without adjustment. If in power consumption control strategy, only matchedUpstream data flow and transmitting power corresponding to downlink data flow, the current received power of terminal is without tuneWhole. If in power consumption control strategy, only match upstream data flow and corresponding the connecing of downlink data flowReceive power, the current transmit power of terminal is without adjustment.
As mentioned above, although the embodiment limiting according to embodiment and accompanying drawing be illustrated, to this skillThe technical staff that art field has general knowledge can carry out various amendments and distortion from above-mentioned record.For example, carry out according to the order mutually different from illustrated method in the technology of explanation, and/or according to sayThe illustrated mutually different forms of method of inscape such as bright system, structure, device, circuit are carried out combinationOr combination, or replace or replace according to other inscapes or equipollent and also can reach suitable effect.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise,Making some being equal to substitutes or obvious modification, and performance or purposes identical, all should be considered as belonging to the present inventionProtection domain.
