[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] IoT communications are developing rapidly, with a wide variety of products, covering every corner of life and work. Among them, IoT communications mainly use SIM card traffic for wireless transmission. There are currently three wireless communication operators on the market, and different regions have also launched different SIMs for the IoT industry. Usually, before IoT products are launched, the compatibility of different types of SIM cards needs to be tested. Among them, the compatibility test of SIM cards refers to testing the availability of SIM cards on mobile terminals. Therefore, there is an urgent need for a SIM card testing method that can test the compatibility of different types of SIM cards.

[0050] It is understood that the terms "first", "second", etc. used in this application can be used in this article to describe various professional terms, but unless otherwise specified, these professional terms are not limited by these terms. These terms are only used to distinguish one professional term from another professional term. For example, without departing from the scope of this application, the first sorting result and the second sorting result can be the same or different.

[0051] In view of the problems existing in the above-mentioned related technologies, an embodiment of the present invention provides a SIM card testing method, which can be applied to a server, a terminal, or a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. Among them, the server can be implemented with an independent server or a server cluster composed of multiple servers. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. It should be noted that the numbers of "multiple" and the like mentioned in each embodiment of the present application all refer to the number of "at least two", for example, "multiple" refers to "at least two".

[0052] In one embodiment, Figure 1 As shown, a SIM card testing method is provided. This embodiment is illustrated by applying the method to a SIM card testing system. The system includes a testing board and m connection ports. The testing board includes m card slots. Each card slot is used to insert a SIM card, and each card slot has a corresponding unique digital label. Each connection port is used to connect a device under test, and each connection port has a corresponding unique digital label. The value range of m is 2 to 8. The method includes the following steps:

[0053] 102. When n types of SIM cards have been inserted into the test board, the n types of SIM cards occupy n card slots, and n types of devices under test have been connected to n connection ports among m connection ports, obtain the numbers corresponding to the card slots into which the SIM cards have been inserted and the numbers corresponding to the connection ports connected to the devices under test, as n target card slot numbers and n target connection port numbers, respectively; the value of n is not greater than m.

[0054] For example, the value of m is 8, and accordingly, the data numbers corresponding to the 8 card slots may be 1, 2, 3, 4, 5, 6, 7 and 8, and the data numbers corresponding to the 8 connection ports may be 1, 2, 3, 4, 5, 6, 7 and 8. It is understandable that the reason why the value of m is not greater than 8 is that the types of SIM cards of various SIM card operators are generally not greater than 8, and the test board including 8 card slots can meet the test requirements of various SIM card operators.

[0055] The connection port may adopt a DUT test interface.

[0056] 104. Combine the target card slot number among the n target card slot numbers with the target connection port number among the n target connection port numbers to obtain n combination results.

[0057] For example, the obtained four target card slot numbers are 1, 2, 3 and 4, and the obtained four target connection port numbers are 5, 6, 7 and 8. Accordingly, the target card slot numbers in the four target card slot numbers are combined with the target connection port numbers in the four target connection port numbers to obtain four combination results. The obtained four combination results can be {(1, 5), (2, 6), (3, 7), (4, 8)}, {(1, 6), (2, 7), (3, 8), (4, 5)}, {(1, 7), (2, 8), (3, 5), (4, 6)} and {(1, 8), (2, 5), (3, 6), (4, 7)}.

[0058] It should be noted that the number of obtained combination results is consistent with the number of target card slot numbers.

[0059] 106. According to each combination result, a compatibility test result of each SIM card under each combination result is obtained.

[0060] For example, a phone card, a city-specific card, b city-specific card and an Internet of Things card are inserted into card slot 1, card slot 2, card slot 3 and card slot 4 respectively, and mobile phones c, d, f and e are connected to connection port 5, connection port 6, connection port 7 and connection port 8 respectively. The four target card slots are numbered 1, 2, 3 and 4 respectively, and the four target connection ports are numbered 5, 6, 7 and 8 respectively. The combination results are {(1, 5), (2, 6), (3, 7), (4, 8)}, {(1, 6), (2, 7), (3, 8), (4, 5)}, {(1, 7), (2, 8), (3, 5), (4, 6)} and {(1, 8), (2, 5), (3, 6), (4, 7)} respectively. In the combination result {(1, 5), (2, 6), (3, 7), (4, 8)}, we can get the availability of the phone card on mobile phone c, the availability of the city a dedicated card on mobile phone d, the availability of the city b dedicated card on mobile phone f, and the availability of the Internet of Things card on mobile phone e. The compatibility test results of the phone card, the city a dedicated card, the city b dedicated card and the Internet of Things card under other combination results can be referred to in the combination result {(1, 5), (2, 6), (3, 7), (4, 8)}, which will not be repeated here.

[0061] In the above SIM card testing method, the number corresponding to the card slot in which the SIM card has been inserted and the number corresponding to the connection port connected to the device under test are obtained as n target card slot numbers and n target connection port numbers respectively; the value of n is not greater than m; the target card slot number among the n target card slot numbers and the target connection port number among the n target connection port numbers are combined to obtain n combination results; based on each combination result, the compatibility test result of each SIM card under each combination result is obtained. In the related art, when testing the availability of n types of SIM cards on n types of devices under test, the n types of SIM cards are usually inserted into a test board, the n types of SIM cards in the test board are sorted according to the identifications, and then the availability of the n types of SIM cards on one of the devices under test is tested respectively according to the sorting numbers. Specifically, for example, the n types of devices under test are respectively device under test 1 and device under test 2, and the n types of SIM cards are respectively SIM card 1 and SIM card 2. SIM card 1 and SIM card 2 are inserted into the test board, and then the availability of SIM card 1 on device under test 1 is tested first, and after obtaining the availability result of SIM card 1 on device under test 1, the availability of SIM card 2 on device under test 1 is tested, and after obtaining the availability result of SIM card 2 on device under test 1, the availability of SIM card 1 on device under test 2 is tested, and then the availability of SIM card 2 on device under test 2 is tested in sequence. That is, in the related art, the compatibility of only one SIM card can be tested at the same time, and the other SIM cards are all in an idle state, and the test efficiency is low. Compared with the related art, since each SIM card is not in an idle state in the process of obtaining the compatibility test result of each SIM card under each combination result according to each combination result, n types of SIM cards can be tested at the same time, thereby improving the test efficiency of the SIM card test. And since when it is necessary to determine the availability of n types of SIM cards on n types of tested devices, the tester only needs to perform one card insertion operation and one operation of connecting the tested device to the test port to complete the compatibility test of n types of SIM cards, thereby improving the test efficiency of the SIM card test.

[0062] In one embodiment, obtaining the number corresponding to the card slot into which the SIM card has been inserted and the number corresponding to the connection port to which the device under test has been connected includes:

[0063] Read the in-position level of each card slot and the in-position level of each connection port;

[0064] Determine whether the in-position level of each card slot is a high level. If it is a high level, determine the card slot label corresponding to the card slot with the in-position level of the high level as the target card slot label. Determine whether the in-position level of each connection port is a high level. If it is a high level, determine the port label corresponding to the connection port with the in-position level of the high level as the target connection port label.

[0065] Among them, a card slot with a high level indicates that a SIM card is inserted into the card slot, otherwise, the card slot has no SIM card inserted. A connection port with a high level indicates that the connection port is connected to a device under test, otherwise, the connection port is not connected to the device under test.

[0066] In this embodiment, by reading the in-position level of each card slot and the in-position level of each connection port; determining whether the in-position level of each card slot is a high level, if it is a high level, determining the card slot number corresponding to the card slot with the high in-position level as the target card slot number, determining whether the in-position level of each connection port is a high level, if it is a high level, determining the port number corresponding to the connection port with the high in-position level as the target connection port number.

[0067] In one embodiment, each card slot and each connection port communicate with the control unit based on a serial port; reading the presence level of each card slot and the presence level of each connection port includes:

[0068] Based on the serial port, a SIM card in-place check instruction is sent to the control unit, and a tested module in-place check instruction is sent to the control unit.

[0069] Among them, the SIM card in-place check instruction can be "at+checksim", and the tested module in-place check instruction can be "at+module", which is not specifically limited in the embodiment of the present application.

[0070] The control unit obtains the analysis result of parsing the SIM card in-place check instruction and the module under test in-place check instruction, and reads the in-place level of each card slot and the in-place level of each connection port respectively according to the analysis result.

[0071] In this embodiment, a SIM card presence check instruction is sent to the control unit based on the serial port, and a tested module presence check instruction is sent to the control unit; the analysis result of the control unit parsing the SIM card presence check instruction and the tested module presence check instruction is obtained, and the presence level of each card slot and the presence level of each connection port are read respectively according to the analysis result.

[0072] In one embodiment, the target card slot number in the n target card slot numbers is combined with the target connection port number in the n target connection port numbers to obtain n combination results, including:

[0073] The n target card slot labels are sorted from small to large to obtain a first sorting result; the n target connection port labels are sorted from small to large to obtain a second sorting result.

[0074] It should be noted that the first sorting result may also be the result obtained by sorting the n target card slot numbers from large to small, and the second sorting result may also be the result obtained by sorting the n target connection port numbers from large to small, and the embodiment of the present application does not specifically limit this. For example, n is 4, the 4 target card slot numbers are 1, 2, 3 and 4, and the 4 target connection port numbers are 5, 6, 7 and 8. The first sorting result may be 1, 2, 3, 4; the second sorting result may be 5, 6, 7 and 8. The first sorting result may also be 4, 3, 2, 1, and the second sorting result may also be 8, 7, 6, 5.

[0075] Gets the combined interval value, which ranges from 0 to (n-1).

[0076] It should be noted that the initial value of the combined interval value can be any integer from 0 to (n-1).

[0077] According to the combination interval value and the sorting number of each target card slot label in the first sorting result, the target connection port label that matches each target card slot label is determined in the second sorting result and combined to obtain a combination result, and the combination interval value is updated, and the above determination, combination and update process is repeated until n combination results are obtained.

[0078] Specifically, according to the combined interval value and the sorting number of each target card slot label in the first sorting result, determining the target connection port label that matches each target card slot label in the second sorting result may include: for the target card slot label with a sorting number i in the first sorting result, calculating the sum between i and the combined interval value, and performing a modulo operation on the sum and n; if the modulo result is not 0, using the target connection port label with a sorting number as the modulo result in the second sorting result as the target connection port label that matches the target card slot label with a sorting number i; if the modulo result is 0, using the target connection port label with a sorting number n in the second sorting result as the target connection port label that matches the target card slot label with a sorting number i.

[0079] For example, if n is 4, the first sorting result is 1, 2, 3, 4; the second sorting result is 5, 6, 7, 8, and the obtained combination interval value is 1. Correspondingly, the target slot number of the target slot number 1 in the first sorting result is 1, the target slot number 2 in the first sorting result is 2, the target slot number 3 in the first sorting result is 3, the target slot number 4 in the first sorting result is 4, the target connection port number 5 in the second sorting result is 1, the target connection port number 6 in the second sorting result is 2, the target connection port number 7 in the second sorting result is 3, the target connection port number 8 in the second sorting result is 4, the combination interval value ranges from 0 to 3, and a combination result is {(1, 6), (2, 7), (3, 8), (4, 5)}; the combination interval value is updated to 2, and a combination result is {(1, 7), (2, 8), (3, 5), (4, 6)}; Update the combination interval value to 3, and get a combination result of {(1, 8), (2, 5), (3, 6), (4, 7)}; Update the combination interval value to 0, and get a combination result of {(1, 5), (2, 6), (3, 7), (4, 8)}.

[0080] In this embodiment, the first sorting result is obtained by sorting n target card slot labels from small to large; the second sorting result is obtained by sorting n target connection port labels from small to large; the combination interval value is obtained, and the value range of the combination interval value is 0 to (n-1); according to the combination interval value and the sorting number of each target card slot label in the first sorting result, the target connection port label adapted to each target card slot label is determined in the second sorting result and combined to obtain a combination result, and the combination interval value is updated, and the above determination, combination and update process is repeated until n combination results are obtained. Since each SIM card has a corresponding device under test in each combination result, in the process of obtaining the compatibility test result of each SIM card under each combination result according to each combination result, each SIM card is not in an idle state, and n types of SIM cards can be tested at the same time, thereby improving the test efficiency of the SIM card test.

[0081] In one embodiment, according to the combined interval value and the sorting number of each target card slot number in the first sorting result, determining the target connection port number matched with each target card slot number in the second sorting result includes:

[0082] For the target card slot number with the sorting number i in the first sorting result, calculate the sum of i and the combined interval value;

[0083] If the sum is not greater than n, the target connection port number with the sorting number of the sum in the second sorting result is used as the target connection port number that matches the target card slot number with the sorting number i; if the sum is greater than n, a modulo operation is performed on the sum and n, and the target connection port number with the sorting number of the modulo result in the second sorting result is used as the target connection port number that matches the target card slot number with the sorting number i.

[0084] For example, n is 4, the first sorting result is 1, 2, 3, 4; the second sorting result is 5, 6, 7, 8, the obtained combination interval value is 2, and i is 3. Accordingly, the target card slot number with the sorting number 3 is 3, and the sum of 3 and the combination interval value 2 is calculated, and the sum is 5. 5 is greater than 4, so a modulo operation is performed on 5 and 4, and the target connection port number with the sorting number 1 in the second sorting result is used as the target connection port number adapted to the target card slot number with the sorting number 3.

[0085] In one embodiment, according to each combination result, a compatibility test result of each SIM card under each combination result is obtained, including:

[0086] For any combination result, the n target card slot labels and the n target connection port labels are paired according to the any combination result.

[0087] For example, n is 4, the four target card slots are numbered 1, 2, 3 and 4, and the four target connection ports are numbered 5, 6, 7 and 8. According to the combination result {(1, 5), (2, 6), (3, 7), (4, 8)}, the four target card slot numbers and the four target connection port numbers are paired, that is, the target card slot number 1 is paired with the target connection port number 5, the target card slot number 2 is paired with the target connection port number 6, the target card slot number 3 is paired with the target connection port number 7, and the target card slot number 4 is paired with the target connection port number 8.

[0088] Determine whether the pairing is successful. If successful, instruct each device under test to send a piece of test data to the server.

[0089] Specifically, determining whether the pairing is successful may include: judging whether the network status of the tested device corresponding to each target connection port number is normal; if they are normal, the pairing is successful; if there is a tested device with an abnormal network status, the pairing fails.

[0090] The test data may be data of any content and any format, and the test data sent by each device under test may be the same or different, which is not specifically limited in the embodiments of the present application.

[0091] Get the server's response result for each test data.

[0092] It should be noted that the response result of the server for each test data is data that is completely identical to each test data. For example, if the test data is 123, the response result is also 123.

[0093] Based on the test data and reply results corresponding to each tested device, the compatibility test result of each SIM card under any combination of results is determined.

[0094] Specifically, for any device under test, it is determined whether the test data and the reply result corresponding to any device under test are the same.
