Example 1
Fig. 1 shows a schematic flowchart of a method for detecting a signal of a SIM card according to a first embodiment of the present invention.
The SIM card signal detection method is applied to SIM cards of at least two operators.
In this embodiment, according to the manufacturer information of the operators in China, the SIM card signal detection method is generally applied to the SIM cards of three operators, namely mobile, universal and telecommunication, and detects the communication quality of the SIM cards of the three operators in a certain area. In other embodiments of the present invention, the SIM card signal detection method may be applied not only to the SIM cards of three operators, namely mobile, universal and telecommunication operators, but also to the subsequently generated SIM cards of other operators.
Step S110, obtaining signal parameters of different network systems compatible with the SIM card.
In this embodiment, the network standards include TD-LTE, FDD-LTE, TD-SCDMA, WCDMA, CDMA2000, and GSM. In other embodiments of the present invention, with further development of network communication, the network standard may further include other newly-generated network standards, for example, a 5G network standard.
In all current network formats, each operator is compatible with 3-4 network formats, for example, a mobile network supports GSM (2G), TD-SCDMA (3G) and TD-LTE (4G); the communication network supports GSM (2G), WCDMA (3G) and FDD-LTE (4G) or TD-LTE (4G); the telecommunications network supports CDMA (2G), CDMA2000(3G) and FDD-LTE (4G).
And accessing a corresponding network according to different network systems compatible with the SIM card, and acquiring the signal parameters of the SIM card in the corresponding network.
For example, if the SIM card signal detection method is applied to a mobile SIM card, a universal SIM card and a telecommunication SIM card, accessing a GSM network, a TD-SCDMA network and a TD-LTE network according to a network format supported by the mobile SIM card, and acquiring signal parameters of the mobile SIM card in the GSM network, the TD-SCDMA network and the TD-LTE network; accessing a GSM (global system for mobile communications) network, a WCDMA (wideband code division multiple access) network and a TD-LTE (time division-long term evolution) network or an FDD-LTE network according to a network system supported by the Unicom SIM card, and acquiring signal parameters of the mobile SIM card in the GSM network, the WCDMA network, the TD-LTE network or the FDD-LTE network; and accessing a CDMA network, a CDMA2000 network and an FDD-LTE network according to a network standard supported by the telecommunication SIM card, and acquiring signal parameters of the telecommunication SIM card in the CDMA network, the CDMA2000 network and the FDD-LTE network.
And acquiring the signal parameters of the connected SIM card at preset time intervals.
For example, signal parameters of the connected SIM card in networks of different network systems are collected every 1 min.
In this embodiment, the time interval may be preset. In other embodiments of the present invention, the time interval can be set in a customized manner according to user requirements or environmental requirements.
The signal parameters comprise a signal strength value, a signal stability value, a signal candidate value and the like received by the SIM card.
The signal strength value is an RSSI value of the signal and can be described in a dBm or asu manner, and the greater the dBm or asu is, the stronger the signal strength is.
In a 2G or 3G network, the relationship between dBm and asu is:
dBm＝-113+2*asu；
assuming that the current received signal quality is-25 dBm, then the corresponding asu is 44; if the current signal is very poor, reaching-100 dBm, then the corresponding asu is 6.5, rounded to 7. Therefore, asu can normally reach 10-30. The larger the number, the better the corresponding signal strength. If the received signal asu is greater than 35 and the signal quality is-43 dBm, then there may be base stations around the full network block 12. If the received signal asu is less than 10 and the signal quality is-93 dBm, the whole network communication module 12 is far away from the base station and is not suitable for communication.
In a 4G network, the relationship between the dBm and the asu is:
dBm＝-140+asu
the signal stability value is a value that quantifies signal stability.
The signal stability value can be described by variance, and the smaller the variance value is, the stronger the signal stability is, and the larger the signal stability value is. The signal stability value can also be described by the fluctuation amplitude of the signal in a preset time interval, and the smaller the fluctuation amplitude is, the stronger the signal stability is, and the larger the signal stability value is.
Fig. 2 is a schematic diagram of signal stability according to an embodiment of the present invention.
For example, the signal strength values obtained by the SIM card 1 in a certain network system are sampled, and the signal strength values at 4 times are respectively: 28. 28.5, 29 and 29; sampling and collecting signal strength values acquired by the SIM card 2 in a certain network system, wherein 4 signal strength values acquired at the same time are respectively as follows: 19.5, 14, 19 and 27.
Then, the variance of the signal strength value of the SIM card 1 is:
DSIM1＝[(28-28.625)2+(28.5-28.625)2+(29-28.625)2+(29-28.625)2]/4≈0.17；
the variance of the signal strength value of the SIM card 2 is:
DSIM2＝[(19.5-19.875)2+(14-19.875)2+(19-19.875)2+(27-19.875)2]/4≈21.55；
comparison DSIM1And DSIM2Due to DSIM1Is less than DSIM2It can be seen that, in the same time interval, the signal stability corresponding to the SIM card 1 is stronger than that of the SIM card 2.
For another example, in a preset time interval, the SIM card 1 performs sampling collection on signal strength values obtained in a certain network system, where a curve formed by connecting the collected signal strength values at 4 moments is a, and a curve formed by connecting the obtained signal strength values of the SIM card 2 is B. In the curve A, the difference value of the signal intensity obtained at every two adjacent moments is small, and the curve A is stable; in the curve B, the difference between the signal intensities obtained at every two adjacent moments is relatively large, and the curve B fluctuates up and down greatly. Therefore, the signal stability of the SIM card 1 is higher than that of the SIM card 2 within 4min, and the signal stability is quantified by a numerical value to obtain a signal stability value of the SIM card.
The candidate value can be described by the number of all base stations communicating with the SIM card, or by the number of other base stations which can perform data transmission with the current SIM card around the base station when the base station performing data transmission with the SIM card fails.
Fig. 3 is a schematic diagram illustrating signal candidate provided by an embodiment of the present invention.
For example, if the number of base stations that can communicate with the SIM card in the current environment is 6, 6 may be used as the signal candidate value of the SIM card.
Or, if the current communication with the SIM card is the base station a, when the base station a is suddenly powered off or abnormal, the base station a cannot normally communicate with the SIM card, and at this time, if there are other base stations around the base station a that can communicate with the SIM card 1, such as the base station B, the base station C, the base station D, the base station E, and the base station F, the number of candidate base stations of the SIM card is 5, that is, the candidate value is 5.
Step S120, performing a first preset operation on the signal parameter of each network standard compatible with each SIM card to generate a network standard evaluation parameter.
The first preset operation includes:
and solving a weighted average of the signal intensity, the signal stability value and the signal candidate value according to a preset weight.
And accessing a corresponding network according to each network type compatible with each SIM card, acquiring signal parameters of the SIM card in the network, performing a first preset operation, and generating network type evaluation parameters of the SIM card in the network corresponding to the network type.
For example, the network system evaluation parameter is signal strength × m% + signal stability value × n% + candidate value × p%, where m% + n% + p% is 1.
Wherein, m, n and p can be preset, and can also be set by self-definition according to the transmission requirement of the current environment.
For example, if the current transmission environment requires signal strength first, then m > n and m > p may be set; if the current transmission environment requires signal stability priority, n > m and n > p may be set.
If m is set to 60, n is set to 30, and n is set to 10 in advance, the signal parameters of the mobile SIM card in the GSM network are 45, 0.17, and 6; the signal parameters in the TD-SCDMA network are 43, 0.25 and 5; the signal parameters in the TD-LTE network are 46, 0.18 and 6. The signal strength values are described in the form of asu.
Then, the network system evaluation parameter of the mobile SIM card in the GSM network is 45 × 60% + (1/0.17) × 30% +6 × 10% >, 29.36;
the network type evaluation parameter of the mobile SIM card in the TD-SCDMA network is 43 × 60% + (1/0.25) × 30% +5 × 10% ═ 27.5;
the network system evaluation parameter of the mobile SIM card in the TD-LTE network is 46 × 60% + (1/0.18) × 30% +6 × 10% >, which is 29.87.
And step S130, performing second preset operation on all network system evaluation parameters to generate comprehensive parameters of the corresponding SIM cards.
In this embodiment, the second predetermined operation is an averaging operation.
For example, if all the network standard evaluation parameters of the obtained mobile SIM card are: 29.36, 27.5, and 29.87, then,
the comprehensive parameter of the mobile SIM card is (29.36+27.5+29.87)/3 is 28.91;
if all the network system evaluation parameters of the connected SIM cards are obtained as follows: 27.45, 25.5, and 29.91, then,
the comprehensive parameter of the Unicom SIM card is (27.45+25.5+29.91)/3 is 27.62;
if all the network system evaluation parameters of the telecommunication SIM card are respectively: 25.33, 26.75, and 29.82, then,
the comprehensive parameter of the telecommunication SIM card is (25.33+26.75+29.82)/3 is 27.3.
In other embodiments of the present invention, the second preset operation may further be to calculate a weighted average of network system evaluation parameters of different network systems of the SIM card according to a predetermined weight.
And step S140, comparing the comprehensive parameters of all the SIM cards and selecting the SIM card with the best communication effect according to the comparison result.
And comparing the acquired comprehensive parameters of all the SIM cards, selecting the SIM card with the best communication effect according to the comparison result, and determining the operator with the best communication effect.
For example, if the obtained comprehensive parameters of the mobile, universal and telecommunication SIM cards are 28.91, 27.62 and 27.3, respectively, it is known through comparison that the mobile SIM card is the SIM card with the best communication effect, and the mobile is the operator with the best communication effect.
In this embodiment, the SIM card signal detection method may be applied to a power grid information acquisition system. In some other embodiments, the SIM card signal detection method may also be applied to other fields, such as the street lamp remote switch by communication of the SIM card used in street lamp management, and for example, a video monitoring device, real-time video transmission by using an SIM card network, and the like.
Example 2
Fig. 4 is a schematic flowchart illustrating a SIM card signal detection method according to a second embodiment of the present invention.
The SIM card signal detection method comprises the following steps:
step S210, obtaining signal parameters of different network systems compatible with the SIM card.
Step S220, performing a first preset operation on the signal parameter of each network standard compatible with each SIM card to generate a network standard evaluation parameter.
And step S230, performing second preset operation on all network system evaluation parameters to generate comprehensive parameters of the corresponding SIM cards.
And step S240, comparing the comprehensive parameters of all the SIM cards and selecting the SIM card with the best communication effect according to the comparison result.
And step S250, selecting the optimal network standard of the operator corresponding to the SIM card according to all the network standard evaluation parameters of the optimal SIM card.
After selecting the SIM card with the best communication effect according to step S240, comparing all network standard evaluation parameters of the best SIM card, and selecting the best network standard of the operator corresponding to the SIM card according to the comparison result.
For example, if the best SIM card is a mobile SIM card, the network system evaluation parameters of GSM, TD-SCDMA and TD-LTE of the obtained mobile SIM card are: 29.36, 27.5, and 29.87, comparing the evaluation parameters of all the network standards, it can be known that the network standard with the best mobile communication effect is TD-LTE.
After selecting the SIM card with the best communication effect, a threshold value can be preset, all network system evaluation parameters of the best SIM card are compared with the threshold value, and 4G is preferentially selected as the best network system in all network systems exceeding the threshold value; and if all the network systems exceeding the threshold do not have 4G network systems, sequentially giving priority to the 3G network systems.
For example, if the best SIM card is a mobile SIM card, the network system evaluation parameters of GSM, TD-SCDMA and TD-LTE of the obtained mobile SIM card are: 29.36, 27.5 and 28.87.
If a preset threshold value is 28, the network systems exceeding 28 are GSM and TD-LTE, and in the network systems exceeding the threshold value, although the network system evaluation parameter of the TD-LTE network is smaller than the network system evaluation parameter of the GSM network, the TD-LTE network system is preferably selected as the network system with the best mobile communication effect. For another example, if the best SIM card is a mobile SIM card, the network system evaluation parameters of GSM, TD-SCDMA and TD-LTE of the obtained mobile SIM card are respectively: 29.36, 28.5 and 27.87.
If the preset threshold value is 28, the network types exceeding 28 are GSM and TD-SCDMA, and in the network types exceeding the threshold value, although the network type evaluation parameter of the TD-SCDMA network is smaller than the network type evaluation parameter of the GSM network, the TD-SCDMA network type is preferably selected as the network type with the best mobile communication effect.
If only GSM is available in the network systems exceeding the threshold, the GSM is selected as the network system with the best mobile communication effect.
The scheme solves the problems of signal instability and signal quality influence caused by switching between different network systems of the same operator.
