On the basis, a qualified threshold of the success rate can be set, and under the condition that the success rate of the short message communication is greater than or equal to the qualified threshold, the performance of the terminal to be tested in the short message service is determined to accord with the expectation, otherwise, the performance of the terminal to be tested is determined to not accord with the expectation, and whether the terminal to be tested needs upgrading, overhauling, scrapping and the like can be further determined. Alternatively, the pass threshold may be 99%, 100%, etc., and the size of the pass threshold may be adaptively set by those skilled in the art according to the actual test conditions, application requirements.

Fig. 2 is a second step flow chart of a short message service testing method provided by an embodiment of the present disclosure, as shown in fig. 2, the method may include a step flow of short message unicast communication shown in steps 210 to 220, a communication control parameter in the short message unicast communication includes a test content and a broadcasting mode, the broadcasting mode includes unicast, and a terminal to be tested includes a unicast transmitting end and a unicast receiving end.

Step 210, a unicast inbound application for communication with a unicast receiving end is sent to a satellite signal simulator through a unicast sending end, and the unicast inbound application for communication is used for indicating short messages with at least two test contents.

After the inbound signal receiving and demodulating processing functions of the satellite signal simulator are started, a unicast communication inbound application can be sent to the satellite signal simulator through the unicast sending end, so that the satellite signal simulator is instructed to carry out unicast short message communication between the unicast sending end and the unicast receiving end. Optionally, unicast short message communication applications with different test contents can be sent through the unicast sending end, for example, unicast short message communication application 1 with 80 english characters, unicast short message communication application 2 with 80 chinese characters, unicast short message communication application 3 with 80 english characters, 80 chinese characters, 5 x symbols, 5 # symbols, and the like can be sent, so as to realize different kinds of short message unicast communication.

Step 220, receiving the unicast communication inbound application and the unicast short message communication application through the satellite signal simulator, and broadcasting unicast short message communication information to the unicast receiving end through the outbound signal of the satellite signal simulator according to the unicast communication inbound application and the unicast short message communication application.

In the embodiment of the disclosure, the unicast communication inbound application sent by the unicast sending end can be received through the satellite signal simulator, so that the unicast short message communication application sent by the unicast sending end is processed. According to the test content of the unicast short message communication application, unicast short message communication information can be sent to a unicast receiving end through an outbound signal of the satellite signal simulator, wherein the test content of the unicast short message communication information is consistent with the test content of the unicast short message communication application.

As shown in fig. 2, the method may also include a step flow of short message broadcast communication, where the communication control parameters in the short message broadcast include test content and a broadcasting mode, and the broadcasting mode is broadcasting, and the terminal to be tested includes an upper terminal and a lower terminal, as shown in steps 230 to 250.

Taking the communication control parameters including the test content and the broadcasting mode as an example, the terminal to be tested may include an upper terminal and a lower terminal, where the upper terminal and the lower terminal are different terminals with authority level up-down relationship, and the broadcasting refers to the communication mode that the upper terminal broadcasts a short message to the lower terminal within the authority range.

Step 230, sending, by the upper terminal, a broadcast communication inbound application and a broadcast short message communication application to the satellite signal emulator, where the broadcast communication inbound application is used to instruct communication with the lower terminal, and the broadcast short message communication application includes a short message of at least two kinds of test contents.

Optionally, the upper terminal may also send a broadcast short message communication application with different test contents, for example, may send a broadcast short message communication application 1 including 80 english characters, a broadcast short message communication application 2 including 80 chinese characters, a broadcast short message communication application 3 including 80 english characters, 80 chinese characters, 5 x symbols, 5 # symbols, and the like.

Step 240, receiving the broadcast communication inbound application and the broadcast short message communication application through the satellite signal simulator, and verifying the broadcast communication inbound application through the satellite signal simulator.

The satellite signal simulator is used for receiving a broadcast communication inbound application sent by an upper terminal, verifying the broadcast authority of the upper terminal with respect to the broadcast communication inbound application, and processing the broadcast short message communication application sent by the upper terminal after verifying that the upper terminal has the broadcast authority corresponding to a lower terminal, otherwise rejecting the broadcast short message communication application and prompting the upper terminal with no broadcast authority corresponding to the lower terminal.

Step 250, broadcasting the broadcast short message communication information to the subordinate terminal according to the broadcast communication inbound application and the broadcast short message communication application through the outbound signal of the satellite signal simulator under the condition that the verification is passed.

Under the condition that the broadcast authority of the upper terminal passes verification, according to the test content of the broadcast short message communication application, the broadcast short message communication information can be sent to the lower terminal through the outbound signal of the satellite signal simulator, wherein the test content of the broadcast short message communication information is consistent with the test content of the broadcast short message communication application.

As shown in fig. 2, the method may also include a step flow of short message multicast communication as shown in step 260, where the communication control parameters in the short message multicast communication include test content and a broadcast mode, where the broadcast mode is multicast, and the terminals to be tested are divided into at least one multicast group, and each multicast group includes at least two terminals to be tested.

The multicast is a communication service that, after grouping user terminals in a satellite system, broadcasts short message information to terminals in the same group, and takes a communication control parameter including test content and a broadcast mode as an example, where the broadcast mode is multicast, at least one multicast group can be obtained by grouping terminals to be tested, and each multicast group includes at least two terminals to be tested, for example, the number of the terminals to be tested in the multicast group can be 2, 3, 4, 5, 6, ··. The number of terminals to be tested in different multicast groups can be the same or different, the same terminal to be tested can be divided into only one multicast group, and can also belong to different multicast groups, and the division of the multicast groups is not particularly limited according to the service requirements of actual multicast communication.

Step 260, broadcasting multicast short message communication information to each terminal to be tested in the multicast group through the outbound signal of the satellite signal simulator, wherein the multicast short message communication information comprises short messages of at least two test contents.

After the satellite signal simulator outbound signal transmitting function is started, multicast short message communication information can be broadcast to all terminals to be tested in the same group in at least one multicast group through the satellite signal simulator, the multicast short message communication information can be set according to test contents, for example, multicast short message communication information 1 comprising 80 English characters can be simultaneously transmitted to 6 terminals to be tested in the same multicast group, multicast short message communication information 2 comprising 80 Chinese characters comprises 80 English characters, 80 Chinese characters, 5 symbols, multicast short message communication information 3 of 5 # symbols and the like.

As shown in fig. 2, the method may also include a step flow of short message emergency search and rescue communication shown in step 270 to step 280, where the communication control parameters in the short message emergency search and rescue communication include test contents, and the test contents also include an emergency search and rescue application message format.

The search and rescue work based on the short message service is supported in extreme and disaster scenes, and higher requirements are put forward on the high efficiency and stability of the short message service of the satellite system, so that the test of the short message emergency search and rescue communication between the terminal to be tested and the satellite system can be performed. The short message emergency search and rescue communication is a communication process that a user terminal sends an emergency search and rescue application message to a satellite system so that the satellite system can obtain relevant information of search and rescue work based on the emergency search and rescue application message. The emergency search and rescue application message is sent based on a preset emergency search and rescue application message format, so that the emergency search and rescue application message is different from other short messages.

Step 270, more than two emergency search and rescue application messages are sent to the satellite signal simulator through the terminal to be tested based on an emergency search and rescue application message format, wherein the emergency search and rescue application message format comprises at least one of identity identification, search and rescue type, inbound frequency point, inbound rate, frequency, time, position coordinates and search and rescue service.

The emergency search and rescue application message format can comprise an identity mark, a search and rescue type, an inbound frequency point, an inbound speed, a frequency, time, position coordinates, search and rescue service and the like. The identity mark is used for uniquely marking identity information of the terminal to be tested, the search and rescue type is used for indicating the type of the terminal to be tested for initiating a call for help, the inbound frequency point is used for indicating the frequency point used for signal transmission between the terminal to be tested and the satellite system, the inbound rate is used for indicating the rate of signal transmission between the terminal to be tested and the satellite system, the frequency is used for indicating the frequency of signal transmission between the terminal to be tested and the satellite system in unit time, the time is used for indicating the time of the terminal to be tested for initiating short message emergency search and rescue communication, the position coordinate is used for indicating the position of the terminal to be tested when the terminal initiates short message emergency search and rescue communication, the position can be expressed by parameters such as longitude, latitude, elevation and the like, and the search and rescue service is used for indicating search and rescue contents of specific applications. On the basis, at least one parameter of the format of the emergency search and rescue application messages among the different emergency search and rescue application messages is different, such as different position coordinates, different search and rescue services and the like.

Taking a beidou satellite navigation system (beidou system for short) as an example, the format of an emergency search and rescue application message is 12 bits "$usrsq, xxxxxxxx (identity mark), x (search and rescue type), x (inbound frequency point), x (inbound rate), x (frequency), hhmmss (time), yyyyy (longitude), c (longitude mark), llll (latitude), c (latitude mark), x.x (elevation), c-c is hh < CR > < LF > (search and rescue service)", as shown in the following table 2:

table 2 Beidou system emergency search and rescue application message format

And 280, receiving an emergency search and rescue application message through the satellite signal simulator, and analyzing the emergency search and rescue application message through the satellite signal simulator.

After receiving the emergency search and rescue application message sent by the terminal to be tested through the satellite signal simulator, the satellite signal simulator can analyze the emergency search and rescue application message based on the format of the emergency search and rescue application message so as to obtain the content of the emergency search and rescue application message. When the analysis of the format of the emergency search and rescue application message is successful and the analysis obtained emergency search and rescue application message is consistent with the transmission of the emergency search and rescue application message through the terminal to be tested, the emergency search and rescue communication of the short message can be considered to be successful.

In the embodiment of the method, in the short message emergency search and rescue communication, the environment conditions such as more interference and weak signal which possibly exist in search and rescue work can be simulated by adding interference signals, reducing signal strength, setting shields and the like, so that the accuracy and reliability of the test on the short message emergency search and rescue communication are ensured.

And 290, counting the success rate of short message communication, and determining the test result of the short message service between the satellite signal simulator and the terminal to be tested according to the success rate.

In the embodiment of the disclosure, step 290 may correspond to the related description of step 120, and is not repeated here.

Taking the unicast communication of the short message as an example, the test result of the unicast communication of the short message can be determined according to the success rate of receiving the unicast short message communication information by the unicast receiving end, wherein the success rate can be determined according to whether the unicast short message communication information received by the unicast receiving end is consistent with the test content of the unicast short message communication application, if so, the unicast communication of the short message is successful, otherwise, the unicast communication failure of the short message is determined, and in the multiple communication, the success rate is determined according to the times of the success of the unicast communication. Optionally, the time of receiving the unicast short message communication information by the unicast receiving end can be counted, and if the difference between the receiving time and the sending time of the unicast sending end is smaller than the preset time, the success of the unicast communication of the short message is determined, otherwise, the failure of the unicast communication of the short message is determined.

The terminal to be tested comprises a unicast receiving end and a unicast transmitting end, so that the performance of the unicast receiving end and the performance of the unicast receiving end can be tested simultaneously in the test of the unicast communication of the short message, when the success rate does not meet the qualification threshold value, specific problem objects can be positioned in the unicast receiving end and the unicast transmitting end according to the unicast service data of the short message, or the signal transmission of the unicast transmitting end can be tested by taking a standard auxiliary terminal as an auxiliary receiving end and the signal reception of the unicast receiving end can be tested by taking the auxiliary terminal as an auxiliary transmitting end, so that specific problem objects can be positioned in the unicast receiving end and the unicast transmitting end.

Therefore, the sensitivity threshold may be set according to the test conditions, the application requirements, and the like, and in the case where the reception sensitivity of the terminal to be tested is lower than the sensitivity threshold, it is determined that the signal reception performance of the terminal to be tested meets the expectations.
