Network, as objective network.
It is understood that the above citing simply needs to pass according to movable equipment in embodiment to illustrate the invention
Defeated data type, determines several specific embodiments of the mode for selection target network, not in order to limit the present invention.
In the embodiment of the present invention, need the data type of transmission according to movable equipment, determine the selecting party for selection target network
Formula, needs the data type of transmission for how according to movable equipment, determines selection mode for selection target network
Specific implementation, the embodiment of the present invention is not particularly limited.
Need the data type of transmission according to movable equipment, after determining the selection mode for selection target network,
The embodiment of the present invention needs the selection mode according to the selection target network determining, selects the target network for transmission data
Network.In the embodiment of the present invention, specific embodiment including but not limited to following two methods of selection target network:
The first: according to the selection mode of the selection target network determining, determine the weight coefficient of each status data；According to
The weight coefficient of each status data, obtain each candidate network weighted results, and using weighted results highest candidate network as
Objective network.
Specifically, when objective network being determined by the method, multiple network parameters of candidate network can be considered
Weight coefficient, to obtain the weighted results of each candidate network；One of network parameter of candidate network can also individually be considered
Weight coefficient, to obtain the weighted results of each candidate network.
Illustrate, if it is video class data that movable equipment needs data a of transmission, the data volume of data a is larger, right
The rate situation of candidate network is most sensitive, and then pays the utmost attention to the candidate network of unauthorized frequency range, to signal during transmission data a
Intensity less demanding.The then data type according to data a, when being transmission data a selection target network, can be with tariffs selectable
Weight coefficient is maximum, and the weight coefficient of frequency range takes second place, and the weight coefficient of signal intensity is minimum.Specifically, for example, the weighting of rate
Coefficient could be arranged to 0.7, and the weight coefficient of frequency range is set to 0.2, and the weight coefficient of signal intensity is set to 0.1, you can comprehensive
Close and consider rate, frequency range and three network parameters of signal intensity, and the weight coefficient according to above-mentioned determination, calculate each candidate network
Weighted results, using one candidate network of weighted results highest as objective network.Or it is it is also possible to data a is less quick
The weight coefficient of the frequency range of sense and signal intensity is set to 0, the weight coefficient of rate is set to 1, you can solely examine simultaneously
Consider one network parameter of rate, according to the weight coefficient determining, calculate the weighted results of each candidate network, by weighted results highest
A candidate network as objective network.
Or, and for example, if movable equipment needs the flight parameter data that data b of transmission is movable equipment, number
Data volume according to b is less, insensitive to network rate, but network condition is required higher, that is, to the signal intensity of network more
Sensitive.According to the data type of data b, when being transmission data b selection target network, can be higher the adding of signal intensity setting
Weight coefficient, and it is rate and the frequency range less weight coefficient of setting.Specifically, for example, the weight coefficient of signal intensity is 0.8,
The weight coefficient of rate and frequency range is set to each 0.1, you can consider signal intensity, rate and three network parameters of frequency range,
And the weight coefficient according to above-mentioned determination, calculate the weighted results of each candidate network, by one candidate's net of weighted results highest
Network is as objective network.Or it is also possible to the weight coefficient of rate less sensitive for data b and frequency range is set to 0, will simultaneously
The weight coefficient of signal intensity is set to 1, you can solely consider one network parameter of signal intensity, according to the weighting system determining
Number, calculates the weighted results of each candidate network, using one candidate network of weighted results highest as objective network.
It is understood that the above citing, simply to illustrate the invention in embodiment, determines the several of objective network
Specific embodiment, not in order to limit the present invention.In specific implementation process, the determination of weight coefficient, can be according to number
Selected according to the selection mode that type determines.
Second: according to the selection mode of the selection target network determining, determine the threshold value of each status data, and will meet
One of the candidate network of each threshold value candidate network is as objective network.
In the embodiment of the present invention, when objective network is determined by the method, for different selection modes, it is candidate network
Each network parameter threshold value corresponding with selection mode is set, and then detect the state parameter of each candidate network whether higher than correspondence
Threshold value, if state parameter candidate network is detected is above corresponding state parameter threshold value it is determined that this candidate network
Meet each threshold value.
Specifically, when objective network being determined by the method, multiple network parameters of candidate network can be considered
Threshold value, using one of candidate network meeting each network parameter threshold value obtaining as objective network；Can also individually examine
Consider one of threshold value specifying network parameter of candidate network, the satisfaction obtaining is specified candidate's net of network parameter threshold value
One of network is as objective network.
Specifically, if the candidate network meeting each threshold value has and only one of which, this is met the candidate network of each threshold value
As objective network；If the candidate network meeting each threshold value has at least two, in all candidate network meeting each threshold value
Select a candidate network as objective network.
It should be noted that if it is determined that the candidate network that movable equipment can access all is unsatisfactory for each threshold value, then according to need
Data type to be transmitted, can will need the data storage of transmission in movable equipment, and periodically obtain each candidate's net
The status data of network, after the candidate network meeting each threshold value is detected, this is met the candidate network of each threshold value as mesh
Mark network.Or however, it is determined that the candidate network that movable equipment can access all is unsatisfactory for each threshold value, can also be according to actual needs
With the data type needing transmission, selection target network in the candidate network being unsatisfactory for each threshold value.It is understood that this
In bright embodiment, this is not particularly limited.
Illustrate, if it is video class data that movable equipment needs data a of transmission, the data volume of data a is larger, right
The rate situation of candidate network is most sensitive, and then pays the utmost attention to the candidate network of unauthorized frequency range, to signal during transmission data a
Intensity less demanding.The then data type according to data a, when being transmission data a selection target network, can be with tariffs selectable
Threshold value is maximum, and the threshold value of frequency range is taken second place, and the threshold value of signal intensity is minimum, you can consider rate, frequency range and signal intensity three
Individual network parameter, and each threshold value according to above-mentioned determination, compare each candidate network collecting state parameter whether meet right
The state parameter threshold value answered, if the candidate network meeting each threshold value only has candidate network 1, using candidate network 1 as target network
Network；Or, if the candidate network meeting each threshold value is candidate network 1, candidate network 2 and candidate network 3, can be in candidate's net
A candidate network is selected as objective network in network 1, candidate network 2 and candidate network 3；If all of candidate network is all discontented
The each threshold value of foot, then preserve data a, until the candidate network meeting each threshold value is detected, the candidate network meeting each threshold value is made
For objective network.
It is understood that the above citing, simply to illustrate the invention in embodiment, determines the several of objective network
Specific embodiment, not in order to limit the present invention.In specific implementation process, the determination of the threshold value of each state parameter, can
Selected with the selection mode being determined according to data type.
Specifically, if the candidate network meeting each threshold value has at least two, in all candidate network meeting each threshold value
Select a candidate network as objective network, have multiple implementations, the embodiment of the present invention is not particularly limited to this.Lift
Example explanation, if candidate network 1, candidate network 2 and candidate network 3 all meet the threshold value of each status data, candidate network 1,
When selecting a candidate network as objective network in candidate network 2 and these three candidate network of candidate network 3, can select at random
Select one of network as objective network；Or, first determination can also be met the candidate network of each threshold value as mesh
Mark network；Or, can also select to meet the candidate network conduct of one of candidate network of each threshold value according to certain principle
Objective network.For example, movable equipment needs transmission data b, after first determining the selection mode of transmission data b, determines rate, frequently
Section and the threshold value of signal intensity, select to meet the candidate network of each threshold value；If candidate network 1 and candidate network 2 all meet corresponding
State parameter threshold value, can be using the candidate network of the unauthorized frequency range of prioritizing selection as objective network；If the time of unlicensed networks
The network condition of network selection network is not good, can be according to generally the least expensive principle, the candidate network conduct of the minimum mandate frequency range of tariffs selectable
Objective network.
The combined method of above two method in the embodiment of the present invention, can also be utilized, determine objective network.Illustrate
Bright, if it is video class data that movable equipment needs data a of transmission, the data volume of data a is larger, the rate to candidate network
Situation is most sensitive, and then pays the utmost attention to the candidate network of unauthorized frequency range, and during transmission data a, the requirement to signal intensity is not
High.The then data type according to data a, when being transmission data a selection target network, can be maximum with the threshold value of tariffs selectable, frequently
The threshold value of section is taken second place, and the threshold value of signal intensity is minimum, you can consider rate, frequency range and three network parameters of signal intensity,
And each threshold value according to above-mentioned determination, whether the state parameter comparing each candidate network collecting meet corresponding state parameter
Threshold value, detects candidate network 1, candidate network 2 and candidate network 3 and meets each threshold value, so needing in candidate network 1, candidate
Determine in network 2 and these three candidate network of candidate network 3 that a candidate network, can be according to data a used as objective network
Data type, determines the weight coefficient of rate, frequency range and signal intensity, and according to the weight coefficient determining, calculates candidate respectively
The weighted results of network 1, candidate network 2 and candidate network 3, if the weighted results highest of candidate network 2, by candidate network 2
As objective network.
Or, and for example, if it is video class data that movable equipment needs data a of transmission, the data volume of data a is relatively
Greatly, most sensitive to the rate situation of candidate network, and then pay the utmost attention to the candidate network of unauthorized frequency range, during transmission data a
Less demanding to signal intensity.The then data type according to data a, when being transmission data a selection target network, can basis
The data type of data a, determines the weight coefficient of rate, frequency range and signal intensity, and according to the weight coefficient determining, counts respectively
Calculate the weighted results of at least one candidate network.On this basis, rate, frequency range and signal intensity three are considered according to above-mentioned
The weighted results that individual network parameter obtains, total threshold value of setting weighted results, and then the total threshold value according to the weighted results determining,
Compare total threshold value of the weighted results of at least one candidate network, one of candidate network of the total threshold value of weighted results will be met
Candidate network, as objective network.
In the embodiment of the present invention, above-mentioned two is illustrated only for illustrating how the combined method using above two method,
Determine objective network, not in order to limit the present invention.And determine that objective network is permissible using the combined method of above two method
There is multiple combination mode, during a specific use, can be selected according to actual needs, the embodiment of the present invention pair
This is not particularly limited.
The embodiment of the present invention, can access for the data type of movable equipment needs transmission and movable equipment
The status data of candidate network, flexibly according to different selection modes, chooses a candidate network as objective network, improves
The reliability of movable equipment transmission data, stability and seriality.
