Embodiment 1
Fig. 1 shows a kind of flow diagram of SIM card signal detecting method of first embodiment of the invention offer.
The SIM card signal detecting method is applied to the SIM card of at least two operators.
In the present embodiment, according to operator of China company-information, the SIM card signal detecting method be usually applied to it is mobile,
The SIM card of three operators of connection and telecommunications, in a certain region, the communication quality to the SIM card of three operator is detected.
In the other embodiment of the present invention, which can be applied not only to mobile, connection and telecommunications three fortune
The SIM card of quotient is sought, it can also be using the SIM card of other operators of subsequent generation.
Step S110 obtains the signal parameter of the compatible different network formats of the SIM card.
In the present embodiment, the network formats include TD-LTE, FDD-LTE, TD-SCDMA, WCDMA, CDMA,
CDMA2000 and GSM.In the other embodiment of the present invention, with the further development of network communication, the network formats may be used also
To include other newborn network formats, for example, 5G network formats etc..
In current all-network standard, the compatible network formats of each operator are 3-4, as mobile network supports
GSM (2G), TD-SCDMA (3G) and TD-LTE (4G)；Connection network support GSM (2G), WCDMA (3G) and FDD-LTE (4G) or
TD-LTE(4G)；Telecommunication network supports CDMA (2G), CDMA2000 (3G) and FDD-LTE (4G).
According to the SIM card, compatible different network formats access corresponding network, and obtain the SIM card in correspondence
Signal parameter in network.
For example, if the SIM card signal detecting method is applied to mobile SIM card, connection SIM card and telecommunications SIM card, according to
Network formats access GSM network, TD-SCDMA network and the TD-LTE network that mobile SIM card is supported, and obtain the movement
Signal parameter of the SIM card in GSM network, TD-SCDMA network and TD-LTE network；The network supported according to connection SIM card
Standard accesses GSM network, WCDMA network and TD-LTE network or FDD-LTE network, and obtains the mobile SIM card in GSM net
Signal parameter in network, WCDMA network and TD-LTE network or FDD-LTE network；The network system supported according to telecommunications SIM card
Formula accesses cdma network, CDMA2000 network and FDD-LTE network, and obtain the telecommunications SIM card cdma network,
Signal parameter in CDMA2000 network and FDD-LTE network.
The signal parameter of connected SIM card is acquired every preset time interval.
For example, acquiring signal parameter of the SIM card once connected in the network of different network formats every 1min.
In the present embodiment, the time interval can be preset.In the other embodiment of the present invention, can according to user demand or
The customized setting time interval of environmental demand.
Wherein, the signal parameter includes signal strength indication, signal stabilization value and the signal candidate that the SIM card receives
Value etc..
The signal strength indication is the RSSI value of the signal, and the mode that dBm or asu can be used is described, dBm or
Asu is bigger, and signal strength is stronger.
Relationship in 2G or 3G network, between the dBm and the asu are as follows:
DBm=-113+2*asu；
It is assumed that the present signal quality that receives is -25dBm, then, corresponding asu is 44；If current signal is very poor, reach
- 100dBm has been arrived, then, it should be just 7 if rounding up that corresponding asu, which is 6.5,.So asu can under normal circumstances
Reach 10-30.Number is bigger, and corresponding signal strength is better.If the asu of received signal be greater than 35, signal quality be-
43dBm, then the whole network, which leads to around module 12, there may be base station.If the asu of received signal is less than 10, signal quality
For -93dBm, then the whole network leads to module 12 apart from base station farther out, be not suitable for being communicated.
Relationship in 4G network, between the dBm and the asu are as follows:
DBm=-140+asu
The signal stabilization value is the numerical value for quantifying signal stabilization.
The signal stabilization value can be described by variance, and variance yields is smaller, and signal stabilization is stronger, signal stabilization
It is worth bigger.The signal stabilization value can also be described by modes such as the fluctuating ranges of signal in predetermined time interval, wave
Dynamic amplitude is smaller, and signal stabilization is stronger, and signal stabilization value is bigger.
It is illustrated in figure 2 a kind of schematic diagram of signal stabilization provided in an embodiment of the present invention.
For example, the signal strength indication that SIM card 1 obtains in a certain network formats is sampled acquisition, at collected 4
The signal strength indication at quarter is respectively as follows: 28,28.5,29 and 29；The signal strength indication that SIM card 2 obtains in a certain network formats into
Line sampling acquisition, same moment collected 4 signal strength indications are respectively as follows: 19.5,14,19 and 27.
So, the signal strength indication variance of SIM card 1 are as follows:
DSIM1=[(28-28.625)2+(28.5-28.625)2+(29-28.625)2+(29-28.625)2]/4≈0.17；
The signal strength indication variance of SIM card 2 are as follows:
DSIM2=[(19.5-19.875)2+(14-19.875)2+(19-19.875)2+(27-19.875)2]/4≈21.55；
Compare DSIM1And DSIM2, due to DSIM1Less than DSIM2, it is known that, in same time interval, the corresponding signal of SIM card 1
Stability is stronger compared to the signal stabilization of SIM card 2.
For another example, within a preset time interval, the signal strength indication that SIM card 1 obtains in a certain network formats is sampled
Acquisition, the curve that the signal strength indication at collected 4 moment is formed by connecting are A, and the signal strength of the SIM card 2 of acquisition connects
Made of curve be B.In curve A, the difference of signal strength acquired in every two adjacent moment is smaller, and curve A is more flat
Surely；In curve B, the difference of signal strength acquired in every two adjacent moment is relatively large, and curve B or more fluctuates larger.
It will thus be seen that in 4min, the signal stabilization of SIM card 1 is higher than SIM card 2, and by the signal stabilization numerical value amount of progress
Change obtains the signal stabilization value of SIM card.
The candidate value can be described by the quantity of all base stations communicated with the SIM card, Huo Zhetong
The excessive base station carried out data transmission with the SIM card is broken down, and can carry out data biography with current SIM card around the base station
The quantity of other defeated base stations is described.
As Fig. 3 shows a kind of schematic diagram of signal candidate provided in an embodiment of the present invention.
For example, if the number of base stations that can be communicated with SIM card in current environment is 6 SIM card can be used as by 6
Signal candidate value.
Alternatively, being base station A if currently being communicated with SIM card, when base station A powers off suddenly or occur situations such as exception
Under, cause base station A cannot be with SIM card normal communication, at this point, can be with SIM card 1 if there are also other base stations around the A of base station
It is communicated, such as base station B, base station C, base station D, base station E and base station F, then, the candidate number of base stations of the SIM card is 5, that is, is waited
Complement value is numerical value 5.
The signal parameter of the compatible each network formats of each SIM card is carried out the first default arithmetic operation by step S120
Generate network formats evaluation parameter.
The first default operation includes:
The signal strength, signal stabilization value and signal candidate value are sought into weighted average according to predefined weight.
Corresponding network is accessed according to the compatible each network formats of each SIM card, obtains letter of the SIM card in the network
After carrying out the first default arithmetic operation after number parameter, generates network formats of the SIM card in the network of corresponding network standard and comment
Valence parameter.
For example, network formats evaluation parameter=signal strength × m%+ signal stabilization value × n%+ candidate value × p%,
In, m%+n%+p%=1.
Wherein, m, n and p can be preset, can also be according to the customized setting of transmission requirement of current environment.
For example, if current transmission environment requires signal strength preferential, then settable m > n and m > p；If current transmission
Environmental requirement signal stabilization is preferential, then settable n > m and n > p.
If presetting m=60, n=30, n=10, the signal parameter of mobile SIM card in gsm networks be 45,0.17 and
6；Signal parameter in TD-SCDMA network is 43,0.25,5；Signal parameter in TD-LTE network is 46,0.18 and 6.
Wherein, signal strength indication is described in a manner of asu.
So, movement SIM card network formats evaluation parameter=45 × 60%+ (1/0.17) in gsm networks ×
30%+6 × 10%=29.36；
Network formats evaluation parameter=43 × 60%+ (1/0.25) of the movement SIM card in TD-SCDMA network ×
30%+5 × 10%=27.5；
Network formats evaluation parameter=46 × 60%+ (1/0.18) × 30%+ of the movement SIM card in TD-LTE network
6 × 10%=29.87.
All-network standard evaluation parameter is carried out the second default arithmetic operation and generates the comprehensive of corresponding SIM card by step S130
Close parameter.
In the present embodiment, the second default operation is operation of averaging.
For example, if all network formats evaluation parameters of the mobile SIM card obtained are respectively as follows: 29.36,27.5 and
29.87 then
The comprehensive parameters of the movement SIM card=(29.36+27.5+29.87)/3=28.91；
If all network formats evaluation parameters of the SIM card of the connection obtained are respectively as follows: 27.45,25.5 and 29.91,
So,
The comprehensive parameters of the connection SIM card=(27.45+25.5+29.91)/3=27.62；
If all network formats evaluation parameters of the SIM card of the telecommunications obtained are respectively as follows: 25.33,26.75 and 29.82,
So,
The comprehensive parameters of the telecommunications SIM card=(25.33+26.75+29.82)/3=27.3.
In the other embodiment of the present invention, the second default operation can also be by the different network formats of the SIM card
Network formats evaluation parameter seek weighted average according to predefined weight.
The comprehensive parameters of all SIM cards are compared and select communication effect according to comparing result by step S140
Optimal SIM card.
The comprehensive parameters of all SIM cards of above-mentioned acquisition are compared, select communication effect best according to comparison result
SIM card, determine the best operator of communication effect.
For example, if obtain movement, connection, the SIM card of telecommunications comprehensive parameters be respectively 28.91,27.62 and 27.3,
It is learnt by comparison, mobile SIM card is the optimal SIM card of communication effect, and mobile is the optimal operator of communication effect.
In the present embodiment, SIM card signal detecting method can be applied to electric network information acquisition system.In some other implementation
In example, SIM card signal detecting method applies also for other field, such as street lamp is realized in the communication of the utilized SIM of road lamp management
Remote switch, for another example, video monitoring apparatus carries out real-time transmission of video etc. using SIM card network.

Standard；If more than there is no 4G network formats in the all-network standard of the threshold value, then, it is successively preferential with 3G network standard.
For example, if optimal SIM card is mobile SIM card, GSM, TD-SCDMA and TD-LTE's of the mobile SIM card of acquisition
Network formats evaluation parameter is respectively as follows: 29.36,27.5 and 28.87.
If a default threshold value is 28, the network formats beyond 28 are GSM and TD-LTE, in the network formats for exceeding threshold value
In, it is still preferential to choose although the network formats evaluation parameter of TD-LTE network is less than the network formats evaluation parameter of GSM network
TD-LTE network formats are the mobile optimal network formats of communication effect.For another example, it if optimal SIM card is mobile SIM card, obtains

27.87。
If a default threshold value is 28, the network formats beyond 28 are GSM and TD-SCDMA, in the network formats for exceeding threshold value
In, although the network formats evaluation parameter of TD-SCDMA network is less than the network formats evaluation parameter of GSM network, still preferential choosing
Taking TD-SCDMA network standard is the mobile optimal network formats of communication effect.
If in the network formats beyond threshold value, only GSM, then choosing GSM is the mobile optimal network of communication effect
