The short message service testing method provided by the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Fig. 1 is a flowchart illustrating steps of a short message service testing method according to an embodiment of the present disclosure, and as shown in fig. 1, the method may include steps 110 to 120. As follows:

step 110, performing at least two short message communications with a terminal to be tested through a satellite signal simulator, wherein at least one communication control parameter of the different short message communications is different, the communication control parameter comprises at least one of a test content and a broadcast mode, the test content comprises at least one of a coding mode and a message length, and the broadcast mode comprises at least one of unicast, multicast and broadcast.

The satellite signal simulator is used for simulating satellite signals supporting the short message communication service, for example, the satellite signal simulator can adopt the working frequency band of the Beidou system and work in the signal frequency bands of S2C, Lf1, Lf2 and the like, so that the short message service in the Beidou system is simulated. The terminal to be tested is a user terminal supporting short message service in a satellite system, can send and receive signals in the working frequency band of the satellite system, and generally comprises terminal equipment configured with a corresponding satellite communication chip, a corresponding module and a corresponding antenna. Configuration parameters such as frequency, channel and bandwidth of the terminal to be tested can be set according to the test requirements of the short message service, for example, the uplink 1615.68MHz and the downlink 2491.75MHz of the terminal to be tested can be set to meet the test requirements of the short message service in the Beidou system. The terminal to be tested can send signals to the satellite signal simulator and receive signals from the satellite signal simulator, so that the short message communication process of the user terminal and the satellite in the satellite system is simulated, and communication testing is realized.

In the embodiment of the disclosure, the communication control parameter may be used to control a satellite signal simulator, a receiving and transmitting mode, content, and the like of a terminal to be tested, and different types of short message communication may be implemented between the signal simulator and the terminal to be tested by adjusting the communication control parameter, where at least one communication control parameter is different between different types of short message communication. It should be noted that, in the embodiment of the present disclosure, only the type of short message communication is limited, but the number of times of short message communication is not limited, for example, when two types of short message communication are performed between the satellite emulator and the terminal to be tested, 1 time of each short message communication may be 2 times, 100 times of each short message communication may be 200 times, or 100 times of one type of short message communication and 50 times of another type of short message communication may be 150 times, that is, the number of times of each short message communication may be more than 1 time, and the number of different types of short message communication may be the same or different, so that the type and number of times of short message communication may be adjusted according to actual test requirements and test conditions.

In one method embodiment of the present disclosure, the communication control parameter includes at least one of test content and broadcast mode.

In the embodiment of the present disclosure, the test content may refer to communication content between the satellite signal simulator and the terminal to be tested, for example, the test content may include a format, content, and the like of a short message transmitted in short message communication; the broadcasting mode can be a communication mode with different signal flow directions between the terminal to be tested and the satellite signal simulator, and can be one-way, two-way, forwarding and the like.

The short messages with different coding modes and different message lengths can be transmitted between the terminal to be tested and the satellite signal simulator to realize various short message communications.

In one method embodiment of the present disclosure, the broadcasting manner includes at least one of unicast, multicast, and broadcast.

In the embodiment of the present disclosure, the broadcast manner may include unicast, multicast, broadcast, and the like, where the unicast is point-to-point communication, and in a satellite system, generally refers to communication between a terminal and a terminal, and may be that a sending end sends communication information to a receiving end through the satellite system; multicasting is intra-group communication, which in satellite systems generally means dividing terminals into different groups so that communication information can be sent to a group of terminals in one communication; broadcasting is communication from an upper terminal to a lower terminal, and in a satellite system, generally means that terminals are hierarchically divided up and down according to authority, so that the upper terminal can transmit communication information to the lower terminal through the satellite system in one communication.

In a method embodiment of the present disclosure, the communication control parameter may further include a signal test.

The signal test can be realized by detecting the capability of the terminal to be tested for supporting and processing signals of S2C, Lf1 and Lf2 in the working frequency band of the satellite system and broadcasting signals of S2C, Lf1, Lf2 and the like to the terminal to be tested through a satellite signal simulator.

And step 120, 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.

The success rate of the short message communication can be counted according to the short message communication flow, for example, whether the short message is successfully sent, received, forwarded, analyzed, stored and the like can be counted, so that the test result of the short message service between the satellite signal simulator and the terminal to be tested can be determined according to the success rate, and the test result can represent the performance of the terminal to be tested in the short message service.

For example, it can be considered that the higher the success rate of short message communication, the better the performance of the terminal to be tested in the short message service. On the basis, a qualified threshold of the success rate can be set, and when 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 be in accordance with the expectation, otherwise, the performance of the terminal to be tested is determined not to be in accordance with the expectation, and whether the terminal to be tested needs to be upgraded, overhauled, scrapped and the like can be further determined. Alternatively, the qualified threshold may be 99%, 100%, etc., and one skilled in the art may adaptively set the size of the qualified threshold according to actual test conditions and application requirements.

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

Taking the example that the communication control parameters include test contents and a broadcast mode, and the broadcast mode is unicast, the terminal to be tested may include a unicast sending terminal and a unicast receiving terminal, where the unicast sending terminal and the unicast receiving terminal may be the same terminal to be tested, that is, a signal is sent by one terminal to be tested in the communication process, and the terminal to be tested receives the signal sent by the terminal to be tested; or, the unicast sending end and the unicast receiving end may also be different terminals to be tested, that is, one terminal to be tested sends a signal during the communication process, and the other terminal to be tested receives the signal sent by the other terminal to be tested.

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

After the satellite signal simulator inbound signal receiving and demodulating processing function is started, a unicast communication inbound application can be sent to the satellite signal simulator through the unicast sending terminal, and therefore the satellite signal simulator is instructed to conduct unicast short message communication between the unicast sending terminal and the unicast receiving terminal. Optionally, a unicast short message communication application with different test contents may also be sent through the unicast sending end, for example, a unicast short message communication application 1 including 80 english characters, a unicast short message communication application 2 including 80 chinese characters, a unicast short message communication application 3 including 80 english characters, 80 chinese characters, 5 symbols, 5 # symbols, and the like may be sent, thereby implementing different types of short message unicast communication.

And step 220, receiving the unicast communication inbound application and the unicast short message communication application through the satellite signal simulator, and broadcasting the unicast short message communication information to a 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 satellite signal simulator can be used for receiving the unicast communication inbound application sent by the unicast sending end, so as to process the unicast short message communication application sent by the unicast sending end. 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 as shown in step 230 to step 250, where the communication control parameters in the short message broadcast include test content and a broadcast mode, the broadcast mode is broadcast, and the terminal to be tested includes a superior terminal and a subordinate terminal.

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 having a relationship between an authority level and a lower level, and the broadcast refers to a communication mode in which the upper terminal broadcasts a short message to the lower terminal within the authority range.

Step 230, sending a broadcast communication inbound application and a broadcast short message communication application to the satellite signal simulator through the superior terminal, wherein the broadcast communication inbound application is used for indicating communication with the inferior terminal, and the broadcast short message communication application comprises short messages of at least two test contents.

After the inbound signal receiving and demodulating processing function of the satellite signal simulator is started, the superior terminal can send a broadcast communication inbound application to the satellite signal simulator, so that the satellite signal simulator is indicated to carry out broadcast communication between the superior terminal and the subordinate terminals, the superior terminal can include at least one subordinate terminal within the broadcast authority range, and when more than two subordinate terminals are included within the broadcast authority range of the superior terminal, the number of broadcast objects in each short message broadcast communication can be controlled, so that different short message broadcast communication can be distinguished, and different short message broadcast service scenes in practical application can be covered. Optionally, broadcast short message communication applications of different test contents may also be sent through the superior terminal, for example, broadcast short message communication application 1 including 80 english characters, broadcast short message communication application 2 including 80 chinese characters, broadcast short message communication application 3 including 80 english characters, 80 chinese characters, 5 × symbols, 5 # symbols, and the like may be sent.

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

The broadcast communication inbound application sent by the superior terminal can be received through the satellite signal simulator, then the broadcast authority of the superior terminal is verified according to the broadcast communication inbound application, the broadcast short message communication application sent by the superior terminal can be processed after the superior terminal is verified to have the broadcast authority of the corresponding subordinate terminal, otherwise, the broadcast short message communication application can be refused, and the superior terminal is prompted to have no broadcast authority of the subordinate terminal through the satellite signal simulator.

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

Under the condition that the broadcast authority of the upper-level terminal passes the 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-level 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 shown in step 260, where the communication control parameter in the short message multicast communication includes test content and a broadcast mode, the broadcast mode is multicast, the terminal to be tested is 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 broadcasts short message information to terminals in the same group after grouping user terminals in a satellite system, and taking communication control parameters including test content and a broadcast mode as an example, and the broadcast mode is multicast, the multicast service can group terminals to be tested to obtain at least one multicast group, where each multicast group includes at least two terminals to be tested, for example, the number of terminals to be tested in the multicast group may be 2, 3, 4, 5, 6, etc. The number of terminals to be tested in different multicast groups may be the same or different, the same terminal to be tested may be divided into only one multicast group or may belong to different multicast groups, and the division of the multicast groups is not specifically limited by the present disclosure according to the service requirements of actual multicast communication.

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

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

The short message emergency search and rescue communication test system supports search and rescue work based on short message service in extreme scenes, disasters and other scenes, and provides higher requirements for high efficiency and stability of the short message service of the satellite system, so that the short message emergency search and rescue communication test can be carried out between a terminal to be tested and the satellite system. The short message emergency search and rescue communication is a communication process in which the user terminal sends an emergency search and rescue application message to the 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.

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

The emergency search and rescue application message can be sent to the satellite signal simulator through the terminal to be tested according to the format of the emergency search and rescue application message, and the format of the emergency search and rescue application message can comprise an identity, a search and rescue type, an inbound frequency point, an inbound rate, a frequency, time, position coordinates, search and rescue services and the like. The identity mark is used for uniquely marking identity information of a terminal to be detected accessed to a satellite system, the search and rescue type is used for indicating the type of the terminal to be detected for calling for help, the inbound frequency point is used for indicating the frequency point used for signal transmission between the terminal to be detected and the satellite system, the inbound rate is used for indicating the rate of the signal transmission between the terminal to be detected and the satellite system, the frequency is used for indicating the frequency of the signal transmission between the terminal to be detected and the satellite system in unit time, the time is used for indicating the time of the terminal to be detected for initiating short message emergency search and rescue communication, the position coordinate is used for indicating the position of the terminal to be detected for initiating the short message emergency search and rescue communication, the position coordinate 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 message is different among different types of emergency search and rescue application messages, such as different position coordinates, different search and rescue services and the like.

Taking a Beidou satellite navigation system (hereinafter referred to as a Beidou system) as an example, the format of the emergency search and rescue application message is 12 bits "$ USRSQ, xxxxxxx (identity), x (search and rescue type), x (inbound frequency point), x (inbound rate), x (frequency), hhmmss (time), yyyyyy.yy (longitude), c (longitude mark), llll.ll (latitude), c (latitude mark), x.x (elevation), c-c × 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 the 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 format of the emergency search and rescue application message is successfully analyzed and the analyzed emergency search and rescue application message is consistent with that sent by the terminal to be tested, the short message emergency search and rescue communication can be considered to be successful.

In one embodiment of the method, in the short message emergency search and rescue communication, the environmental conditions such as much interference, weak signals and the like possibly existing in the search and rescue work can be simulated by adding interference signals, reducing the signal strength, setting shielding objects 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 the 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 present disclosure, step 290 may correspond to the related description of step 120, and is not repeated herein to avoid repetition.

Taking short message unicast communication as an example, the test result of short message unicast communication can be determined according to the success rate of receiving unicast short message communication information by a unicast receiving end, wherein the success rate can be counted according to whether the unicast short message communication information received by the unicast receiving end is consistent with the test content applied by unicast short message communication, the success rate of short message unicast communication is determined under the condition of consistency, otherwise, the failure of short message unicast communication is determined, and the success rate is determined according to the times of successful unicast communication in multiple communications. Optionally, the time for receiving the unicast short message communication information by the unicast receiving end may also be counted, and when the difference between the receiving time and the sending time of the unicast sending end is smaller than the preset time, it is determined that the short message unicast communication is successful, otherwise, it is determined that the short message unicast communication is failed.
