According to the battery capacity value and operating mode of the target terminal received, the target terminal recorded before update Battery capacity value.For example, the battery capacity value for the target terminal that server is recorded is 75%, after having run a period of time, mesh The battery capacity value of mark terminal is changed, and after consuming electricity, has become 56%, server has received target terminal hair Battery capacity value after the variation sent, then original battery capacity value 75% is updated to 56% by server.It is worth noting that It is only enumerated herein for battery capacity value, is not to limit.
S432, the operating mode for identifying target terminal.
After the battery capacity value to target terminal is updated, identify that the operating mode of target terminal, basis of characterization are The operating mode that target terminal is sent to server.
If S4321, operating mode are Class A, judge whether the battery capacity value of target terminal is higher than the second electricity Threshold value judges whether the traffic density of target terminal is higher than the first traffic density threshold value if being higher than, if being higher than, to correspondence Target terminal send switching working mode to Class B operating mode order.
When the operating mode for determining target terminal is Class A, then illustrate that the working condition of the target terminal is low Energy consumption, low row communications status further judge mesh to guarantee that the downlink communication demand of target terminal is reasonably met Whether the battery capacity value of mark terminal is greater than the second power threshold, according to operation needs, sets the second power threshold, the second electricity Threshold value determines the minimum charge value of target terminal operation Class B operating mode, i.e., operational terminal is by operating mode Class A The minimum battery capacity value for switching to operating mode Class B, is herein not specifically limited the numerical value of the second power threshold, can It can be 50% (battery field value 63 in DevStatusAns order) with identical as the first power threshold, it can also be with First power threshold is different, is set according to the specific carrying out practically of target terminal, does not do rigid restriction herein.Such as The battery capacity value of fruit target terminal is higher than the second power threshold, then proves that target terminal has enough electricity to run energy consumption Higher, downlink communication quality better quality mode has operating mode is higher to the downstream traffic and higher work of energy consumption The condition of pattern switching, can according to demand by the operating mode of target terminal by consume energy it is minimum, downlink communication quality is minimum Class A operating mode switches to higher, the higher Class B operating mode of downlink communication quality that consumes energy, and generates switch operating Mode to Class B instruction.
Further, has operating mode is higher to downstream traffic and energy consumption more senior engineer in the battery capacity value of terminal When the condition of operation mode switching, in order to carry out the switching of operating mode according to specific requirements, can further it judge whether there is The demand switched to downstream traffic more height mode, judges traffic density.According to the pass between energy consumption and operating mode System, sets the first traffic density threshold value, and the first traffic density threshold value identifies the traffic carrying of operating mode Class B operation Value also identifies the upper limit value of the traffic of operation operating mode Class A.
The traffic density between target terminal and server this moment is obtained, if current traffic density is close higher than the first communication Threshold value is spent, then the target terminal for illustrating at this time, which has, cuts operating mode to the operating mode for having more high traffic bearing capacity The demand changed, at this point, the battery capacity of target terminal also meets operating mode is higher to downstream traffic and energy consumption more senior engineer The condition of operation mode switching, therefore target terminal can be set and switch to operating mode and have more high traffic bearing capacity Operating mode is switched to Class B by Class A by operating mode, generate the instruction of switching working mode to Class B.
If the current traffic density of target terminal is lower than the first traffic density threshold value, illustrate that target terminal is run at this time Operating mode, it is sufficient to meet current downstream traffic, without the operating mode of switching working mode to high traffic, then tie up It holds current operation mode, realizes energy-efficient purpose, i.e., when the traffic density of target terminal is lower than the first traffic density threshold value, dimension The operating mode Class A of target terminal at this time is held, so that energy consumption is minimum.
If S4322, operating mode are Class C, it is close to judge whether the traffic density of target terminal is higher than the second communication Threshold value is spent, if being higher than, sends the order of switching working mode to Class A operating mode to corresponding target terminal.
When the operating mode for determining target terminal is Class C, then illustrate that the working condition of target terminal at this time is Highest energy consumption, highest downlink traffic condition, since the powering mode of target terminal at this time is battery power supply, then in order to reduce consumption Can, the operating mode of target terminal is switched to the operating mode of relatively low energy consumption, Class B or Class A.In order to guarantee The downlink communication demand and energy consumption of target terminal are reasonably matched, at this point, the traffic density of target terminal is judged, with determination Which kind of energy consumption, which kind of downstream traffic work status mode traffic density this moment needs to switch to.
According to the relationship between energy consumption and operating mode, the second traffic density threshold value, the second traffic density threshold value mark are set The traffic bearing value for having known operating mode Class B operation also identifies the upper of the traffic of operation operating mode Class A Limit value.Second traffic density threshold value can be set as identical as the first traffic density threshold value, can also be different, it is preferable that this reality It is identical as the second traffic density threshold value to apply the selected first traffic density threshold value of example.
If the traffic density of target terminal is higher than the second traffic density threshold value, illustrate the communication of target terminal at this time Amount is in high requirements, and the operating mode of the minimum traffic bearing capacity of lowest energy consumption can make downlink quality reduce, in order to full The demand of sufficient downstream traffic, while realizing energy conservation, the operating mode of target terminal is switched into energy consumption and the traffic carries energy The medium Class B of power.Generate the instruction of switching working mode to Class B.
If the traffic density of target terminal is lower than the second traffic density threshold value, illustrate the communication of target terminal at this time Amount is in lower demand, and the operating mode of the minimum traffic bearing capacity of lowest energy consumption can be used, logical in order to meet downlink The demand of traffic, while realizing energy conservation, the operating mode of target terminal is switched into energy consumption and traffic bearing capacity is minimum Class A generates the instruction of switching working mode to Class A.
The instruction that operating mode switches is sent to target terminal, it is preferable that in the present embodiment, application layer is selected to send mesh Mark the switching command of the operating mode of terminal.
