[0002] The satellite system is an infrastructure that provides all-weather, all-day, high-precision positioning, navigation and timing services to users around the world. Due to the limited channel resources of satellite system communication, the time frequency of short messages sent by terminals connected to the satellite system is limited. In the related art, the frequency of short message transmission is controlled by pre-setting different short message transmission frequency parameters in the card corresponding to the satellite system. This method of limiting the frequency of short message transmission is static. Once the frequency parameters of the card are burned in, the frequency of short message transmission is fixed and cannot be changed later.

[0003] However, in actual scenarios, the load of the satellite system is different in different time periods. Some areas have a high demand for sending short messages, while some areas have a low demand for sending short messages. At this time, it may be unreasonable to use the same short message sending frequency for each area. Areas with a high demand for sending short messages will experience communication road congestion, resulting in users in this area being unable to successfully send short messages.

[0020] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] Figure 1 is a schematic diagram of a message sending method provided in an embodiment of the present application. The method can be executed by a satellite. In other words, the method can be executed by software or hardware installed on the satellite. The method includes the following steps:

[0023] S101: Determine the load parameters of the satellite.

[0024] The satellite load parameters may include at least one of the following parameters: the number of users sending short messages, the number of short messages sent, the amount of short message received data, the response delay, the user's location information, etc. Specifically, in this step, the above parameters may be monitored within a cycle.

[0025] S102: Determine whether to restrict a terminal from sending short messages according to a load parameter of the satellite, wherein the terminal is within a coverage area of ​​the satellite.

[0026] Specifically, the coverage area of ​​the satellite includes at least one, which can determine to restrict terminals in the coverage area of ​​the satellite from sending short messages when the load parameter of the satellite is greater than a threshold value, and can determine not to restrict terminals in the coverage area of ​​the satellite from sending short messages when the load parameter of the satellite is not greater than a threshold value.

[0027] S103: When it is determined that the terminal is restricted from sending short messages, a broadcast message is sent to the terminal, where the broadcast message carries service restriction information, and the service restriction information is used to notify the terminal to restrict sending short messages.

[0028] The message sending method provided by the embodiment of the present invention determines the load parameters of the satellite; determines whether to restrict the terminal from sending short messages according to the load parameters of the satellite, wherein the terminal is within the coverage area of ​​the satellite; and in the case where it is determined that the terminal is restricted from sending short messages, sends a broadcast message to the terminal, wherein the broadcast message carries service restriction information, and the service restriction information is used to notify the terminal to restrict the sending of short messages. According to the load condition of the satellite, when the load of the satellite is too large, the terminal within the coverage area of ​​the satellite can be restricted from sending short messages, so as to avoid communication road congestion in areas with high demand for sending short messages, effectively balance the load of the satellite system, and prevent information loss due to excessive load. The frequency of the terminal sending short messages can be dynamically and real-time directionally controlled, and resources can be directed and allocated to the users or areas most in need according to different users in different areas.

[0029] In another implementation, step S102 may specifically include: determining the average load of each of the coverage areas according to the load parameters of the satellite; determining a service restriction area from the multiple coverage areas according to the average load of each of the coverage areas; and determining to restrict the terminals in the service restriction area from sending short messages. Thus, it is possible to selectively restrict the terminals in some areas of the satellite coverage area from sending short messages, so as to avoid communication road congestion in areas with high demand for sending short messages.

[0030] Specifically, optionally, the satellite may include at least one coverage area. In this step, the average load of each coverage area of ​​the satellite may be calculated, and the load distribution diagram of each coverage area may be fitted. When the average load of the coverage area served by the satellite is below the threshold, no processing is required, and there is no need to restrict the user from sending short messages. Figure 2 As shown, Figure 2 Taking the satellite coverage area as an example, when the average load of the coverage area is greater than the threshold coverage area, the coverage area can be recorded as area: A. When the average load of the coverage area is less than the threshold coverage area of ​​area A, the coverage area is recorded as area: B. Optionally, the coverage area can be a center position information, plus the radius of the center of the circle, or a focus position information, with a long axis, a short axis, etc. In the coverage areas of area A and area B, short message service restrictions need to be performed to reduce the frequency of short message sending by users in the coverage area of ​​area B, so as to allocate more limited channel resources to people in the coverage area of ​​area A.

[0031] In another implementation, step S102 may specifically include: receiving the location of a target event sent by a target server; determining a service restriction area according to the location of the target event; and determining to restrict terminals in the service restriction area from sending short messages.

[0032] Specifically, the satellite can access the server corresponding to the target event. For example, the target event is an address, and the satellite can access the server of the seismic network. The location of the target event can be, for example, the epicenter location information. When the epicenter location information transmitted by the seismic network is monitored, the location information of the target event is recorded as area: A, and the surrounding area of ​​the earthquake area is recorded as area: B. In the earthquake area, the ground mobile network facilities are often severely damaged, and people often send short messages continuously because of panic, occupying too many channel resources. At this time, it is also necessary to limit area: A to ensure that the victims in the earthquake area can send short messages for help in time. In this case, although the real-time load information is not high, it can be expected that the business volume in the area will surge soon. Then, it is necessary to immediately limit the frequency of sending short messages in area A. Therefore, the embodiment of the present application can limit the sending of short messages by terminals in the target event-related area when the load of the satellite in the target event-related area is too large, so as to avoid the phenomenon of communication road congestion in areas with high demand for sending short messages.

[0033] In one implementation, step S103 may include one of the following methods:

[0034] Mode 1: Sending broadcast messages in multiple beams of the satellite, wherein the service restriction information includes a service restriction area. Figure 2 As shown, the service restriction information includes the service restriction area A.

[0035] After receiving the broadcast message, the terminal can determine whether it is in the service restriction area based on its own location, or it can send its own location to the satellite. The satellite receives the terminal location information sent by the terminal; based on the terminal location information, it determines whether the terminal is in the service restriction area A, and sends a determination result to the terminal. The determination result is used to indicate whether the terminal is in the service restriction area. For example, a determination result of 1 indicates that the terminal is in the service restriction area A.

[0036] For example, the same broadcast message is sent in all beams of the satellite, and the broadcast message rule needs to carry the location information of the restricted area; if the location information of two areas needs to be broadcast, rule4 {traffic limit type: beidou short message; traffic limit frequency: F4; Trafficlimit time: T4; Traffic limit area: area A} is broadcast in the first broadcast cycle, and rule5 {trafficlimit type: beidou short message; traffic limit frequency: F5; Traffic limittime: T5; Traffic limit area: area B} is broadcast in the second broadcast cycle.

[0037] Mode 2: Send the broadcast message on the beam corresponding to the service restriction area. Figure 2 As shown, the broadcast message is sent on the beam corresponding to the service restriction area A. In other words, the broadcast message is not sent on the beam corresponding to the non-service restriction area B.

[0038] For example, the satellite obtains the beam information of the position information pair from the internal database. For example, area A corresponds to beam 1 and area B corresponds to beam 5. Then the service restriction information for area A is only sent on beam 1, and the sending format is as follows: rule 4 {traffic limit type: beidou short message; traffic limit frequency: F4; Traffic limit time: T4;} For the service restriction information for area B, it is only sent on beam 5 {traffic limit type: beidou short message; traffic limit frequency: F5; Traffic limit time: T5}. In this way, the broadcast information sent does not need to carry the service restriction area information, because the satellite beam is directional, and less location information can be carried, which can save limited bandwidth resources.

[0039] Optionally, the fields in the service restriction information are used to indicate at least one of the following: whether to restrict the terminal from sending short messages, service restriction type, service restriction probability, service restriction time, and service restriction area.

[0040] Optionally, in this step, the following protocol extension fields may be added to the relevant broadcast message, thereby implementing the broadcast information of the embodiment of the present application by extending the existing message. For example, as shown in Table 1:

[0041] Table 1

[0042]

[0043]

[0044] Among them, bit 0: control information (Control info), indicating whether there is service restriction information, 1 indicates that the service restriction information is carried, and 0 indicates that the service restriction information is not carried.

[0045] Bit 1 and bit 2: Traffic limit type, which can be short message or voice. 0 indicates short message; 1 indicates voice; 2 and 3 are reserved.

[0046] Bit 3, Bit 4, Bit 5, Bit 6: The service restriction probability ranges from 0 to 99. The service restriction probability can be the probability of successful message transmission. For example, 80 indicates that the probability of successful message transmission by the terminal is 80%. In other words, by limiting the probability of successful message transmission by the terminal, the terminal is restricted from sending short messages, and the frequency of short messages received by the satellite is limited.

[0047] Bit 7, bit 0, bit 1, bit 2: traffic limit time, for example, 0 means 1 minute, 1 means 5 minutes, 2 means 15 minutes, 3 means 20 minutes, etc.

[0048] Bit 3, bit 4: traffic limit area indicates a service restriction area, such as service restriction area A. The service restriction area can be periodically sent in a broadcast message according to the above coding format. If more than two service restriction information need to be broadcast simultaneously, the restriction information of area A can be sent in the first broadcast message period, and the restriction information of area B can be sent in the second broadcast message period.

[0049] Thus, the terminal receives the satellite broadcast message, parses out the protocol extension field, and if bit 0 is 0, processes it as a normal satellite broadcast message. If bit 0 is 1, parses out each field and stores it. It is assumed here that the parsed information is:

[0050] traffic limit type: beidou short message

[0051] Traffic limit frequency: 80

[0052] Traffic limit time: 10 minutes

[0053] Traffic limit area:area A

[0054] The terminal obtains its own location information, which is recorded as area: E, and calculates whether area E is within the area described by area A. If not, the message can be discarded. If it is within the area of ​​area A, if there is no location information, it is considered that the service restriction information applies to the area, and the sending of short messages is restricted.

[0055] Figure 3 is a schematic diagram of a message sending method provided in an embodiment of the present application. The method can be executed by a satellite. In other words, the method can be executed by software or hardware installed on a satellite. Figure 3 Taking Beidou satellite as an example for illustration, but the protection scope of this application is not limited to Beidou satellite, the method includes the following steps:

[0056] S301: Calculate the average load of each area of ​​the Beidou satellite according to the received data volume of the Beidou short message, the response delay, the location information of the Beidou user and other parameters, and fit the load distribution diagram of each area.

[0057] S302: Determine whether the average load of any area in a cycle exceeds a predetermined threshold.

[0058] When the average load of a certain area in a period exceeds a predetermined threshold, the area is determined as a service restriction area.

[0059] S303-S310: When the average load of an area exceeds the threshold (referred to as areaA here), determine how much the threshold is exceeded. If it exceeds 10%, enter S304 and set the corresponding short message service control information, which is called rule 1 (rule1) {traffic limit type: beidou short message; traffic limit frequency: F1; Traffic limit time: T1; Traffic limit area: area A}; If it exceeds 20% of the threshold, enter S306 and set the corresponding short message service control information, which is called rule2 {traffic limit type: beidou shortmessage; traffic limit frequency: F2; Traffic limit time: T2; Traffic limit area: area A}; Similarly, according to other corresponding values ​​exceeding the threshold, different service control information is set... By exceeding different levels of the threshold, it is possible to dynamically control the frequency of users sending short messages at different times, so as to balance the load; If it exceeds 50%, enter S309 and determine whether the surrounding neighboring areas exceed the established threshold (referred to as areaA here). B), if not, then enter S310, and limit the service control information of area A and area B at the same time, (the service control information of area A is recorded as rule 4, and the service control information of area B is recorded as rule 5, rule4{trafficlimit type: beidou short message; traffic limit frequency: F4; Traffic limittime: T4; Traffic limit area: area A}; rule5{traffic limit type: beidou shortmessage; traffic limit frequency: F5; Traffic limit time: T5; Traffic limit area: area B}. In other words, the service restriction information is determined according to the proportion of the load value of the satellite exceeding the preset load threshold, wherein the service restriction information is used to: notify the terminal to limit the sending of short messages; or notify the neighboring area of ​​the area to which the terminal belongs to limit the sending of short messages, and the service restriction information carries corresponding rules, and the rules include the limit frequency and limit time of the area.Therefore, through different rules in the service restriction information, it is possible to transfer resources from some areas of multiple areas covered by the satellite to another area, for example, transfer part of the resources of area B to area A.

[0060] S311: The Beidou system will connect to the target event server and monitor whether there are emergency events such as earthquakes and tsunamis. If so, it will immediately obtain the location information of the event and enter S310 to set the business control information of the emergency area and neighboring areas to improve the success rate of short message sending in the emergency time area.

[0061] After that, combine Figure 1 As shown, the broadcast message can be sent to the terminal, and the terminal receives the satellite broadcast message and controls the sending of the message.

[0062] Figure 4 is a schematic diagram of a message sending method provided in an embodiment of the present application. The method can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. The method includes the following steps:

[0063] S401: receiving a broadcast message carrying service restriction information, wherein the service restriction information is used to restrict a terminal from sending short messages.

[0064] Optionally, the field in the service restriction information is used to indicate at least one of the following:

[0065] Whether to restrict the terminal from sending short messages;

[0066] Type of business restriction;

[0067] Probability of business restriction;

[0068] Business restriction time;

[0069] Business restricted areas.

[0070] like Figure 5 As shown, Figure 5 The Beidou satellite is used as an example for illustration, but the protection scope of the present application is not limited to the Beidou satellite. This step may include the following steps:

[0071] S501: Receive and parse broadcast messages within a standard period.

[0072] S502, if bit 0 of the broadcast message protocol extension field is 0, process the broadcast message according to the normal Beidou satellite broadcast message. If bit 0 is 1, parse out each field according to S102.

[0073] S503: Determine whether there is a traffic limit area field in the broadcast message content, and if so, proceed to S504.

[0074] S504: Obtain the current location information of the UE and calculate whether it is within the traffic limit area parsed in S503. If not, discard the information. If yes, proceed to S505.

[0075] S505: Start the timer and set the timer to the traffic limit time.

[0076] S402: Control the frequency of sending Beidou short messages according to the service restriction information.

[0077] Optionally, if the service restriction information includes a service restriction area, determine whether the terminal is in the service restriction area corresponding to the restriction information according to the location of the terminal; if the terminal is in the service restriction area, control the frequency of sending short messages according to the restriction information; or if the service restriction information does not include a service restriction area, control the frequency of sending short messages according to the service restriction information, such as reducing the frequency of sending short messages. Optionally, a random number may be generated; if the random number is greater than a predetermined service restriction probability, stop sending the short message; if the random number is less than a predetermined service restriction probability, send the short message.

[0078] Combination Figure 6 As shown, Figure 6 The Beidou satellite is taken as an example for explanation, but the protection scope of the present application is not limited to the Beidou satellite, and this step may include the following steps.

[0079] S601: The user has a short message sending requirement

[0080] S602: Determine whether the timer (Timer) has timed out. If so, decide whether to send a Beidou short message according to the default rules; if the timer has not timed out, enter S603.

[0081] S603: The terminal generates a random number between 0 and 99. If the random number is less than the traffic limit frequency, the condition for sending the Beidou short message is met, and then the process proceeds to S604 to send the Beidou short message. If the random number is greater than the traffic limit frequency, the condition for sending the Beidou short message is not met, and then the process proceeds to S605, and the terminal does not send the Beidou short message. Thus, the embodiment of the present application can limit the sending of Beidou short messages by terminals in the coverage area of ​​the Beidou satellite according to the load of the Beidou satellite, when the load of the Beidou satellite is too large, so as to avoid the phenomenon of communication road congestion in areas with high demand for sending Beidou short messages, effectively balance the load of the Beidou system, and prevent information loss due to excessive load. The frequency of sending Beidou short messages by the terminal can be dynamically and real-time controlled, and resources can be allocated to the users or areas in most need according to different users in different areas.
