[0040] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions in the present disclosure will be described clearly and completely in the following with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some embodiments of the present disclosure, but not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present disclosure.

The terms "upper", "lower", and the like indicate the orientation or positional relationship shown in the drawings, and are used only to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. Unless otherwise expressly specified and limited, the terms "mounting", "connecting", "connecting" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected internally between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] The terms "first", "second", and the like in 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 thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" means at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0043] At present, the service needs of satellite communication users mainly include avoiding the idle state of point beams and the long-term saturated working state of point beams, and need to specify different service levels for different users in a region, while providing the corresponding commitment information rate (CIR) or maximum information rate (MIR), and specifying the service disablement of a specific user terminal in the region. Due to the frequency limitation of certain geographical areas on user terminals, high-throughput satellite communication systems can limit terminal withdrawal from the network, so that the terminal is in a dormant mode until the terminal leaves the area and accesses the network.

[0044] Currently, the service area of high-throughput satellite communication is limited in two modes: a service area mode based on authentication issued by a gateway station and a mode in which a satellite terminal locally determines a service area map. In the service area mode based on authentication issued by the gateway station, the gateway station issues the service area map to the satellite terminal through a broadcast channel, and the satellite terminal checks the service area mode of the network from the broadcast message before entering the network, and determines whether to enter the network according to the service area map. In the mode in which the satellite terminal locally determines the service area map, the satellite terminal obtains the latest service area map from the gateway station through a management channel after entering the network and saves it locally, and determines whether to enter the network according to the old version of the service area map saved locally before entering the network.

[0045] The above service area limiting mode lacks unified calibration of the service area map, and the restriction areas such as the silent area, dormant area and information rate (such as CIR and MIR) of the satellite terminal are not implemented in the same service area map. Some of the restriction areas are based on the service area mode of authentication issued by the gateway station, and some of the restriction areas are based on the mode determined locally by the satellite terminal, which causes the complexity of the configuration operation of the service area map and the inflexibility of the use of the service area map.

[0046] To solve the above technical problems, the present disclosure provides a service area limiting method, device, equipment, medium and program product. FIG. 1 is a flowchart of a service area limiting method provided by an embodiment of the present disclosure. Referring to FIG. 1, the service area limiting method provided by the embodiment of the present disclosure can include the following steps 100-300.

[0047] Step 100: Obtain the position information of each satellite terminal of any terminal type, and obtain the limiting condition corresponding to the terminal type.

[0048] Step 200: Determine the service area of the satellite terminal of the terminal type according to the position information, and calibrate the service area based on the limiting condition to generate the service area map corresponding to the terminal type.

[0049] Step 300: Limit the service area of the satellite terminal of the terminal type based on the service area map.

[0050] In the embodiment of the present disclosure, the limiting condition includes the area type, the promised information rate and the highest information rate; and the area type includes the service area, the dormant area and the silent area.

[0051] Firstly, it needs to be explained that the service area limiting method provided by the embodiments of the present disclosure is applied to a high-throughput satellite communication system, and specifically is applied to a gateway of a high-throughput satellite communication system. When limiting the service area, the position information of each satellite terminal of any terminal type is obtained, and the limiting condition corresponding to the terminal type is obtained. In the high-throughput satellite communication system, there are multiple different types of satellite terminals, and different limiting conditions exist for different types of satellite terminals. The limiting condition is used to define the service level in the service area corresponding to a specific geographic area.

[0052] According to the position information of each satellite terminal under any terminal type, the service area of the satellite terminal of the terminal type is circled / determined, and the circled service area is marked based on the limiting condition corresponding to the terminal type, to generate a service area map corresponding to the terminal type. The service area defines a geographic area that is independent of the range of a satellite beam, and according to the defined geographic area, differentiated services are provided for users. A user can have a batch of satellite terminals of the same type, and according to the limiting condition of the service area corresponding to the satellite terminal of the same type, the gateway circles the service area of the entire network through the position information such as the latitude and longitude of the terminal. The service area is composed of one or more closed areas surrounded by contour lines, and if multiple contour lines are used to define the service area, the contour lines do not have to be continuous. According to the limiting condition of the different areas to which the service area belongs corresponding to the terminal type of the satellite terminal (the limiting condition includes the area type, the committed information rate CIR, and the maximum information rate MIR, etc.), the service limiting condition of the different areas is marked, to form a service area map. The area type further includes a service area, a quiet area, and a dormant area. Superimposing the service area map and the beam map can be used to control the communication service capability of the satellite terminal in the area. The definition of the service area is independent of the range of the satellite beam, but the service area map can be superimposed with the beam map to control the communication service capability of the satellite terminal, thereby improving the use flexibility of the service area map.

[0053] According to the generated service area map, the service area of the satellite terminal of the corresponding terminal type is limited. Optionally, the service area maps corresponding to different types of satellite terminals are different, and the limiting conditions of different types of satellite terminals in the same geographic area can also be different, so that when the same geographic area is used as the service area of different types of satellite terminals, the limitation of the communication service capability of different types of satellite terminals is also different, thereby differentiated services can be provided for users in the same area. When limiting the service area of the satellite terminal, according to the position of the satellite terminal, the service area in which the satellite terminal is located in the service area map is determined, and the communication service capability of the satellite terminal is limited based on the limiting condition marked in the service area.

[0054] In the embodiment, the service area map is generated by defining the service area of the same type of satellite terminal according to the location of each satellite terminal and marking the defined condition in the service area map, and the service area of the same type of satellite terminal is defined based on the service area map. The service area of different types of satellite terminals can be flexibly defined, and the defined condition of the satellite terminal can be marked in the same service area map, which reduces the complexity of the configuration operation of the service area map and improves the flexibility of the service area map.

[0055] In some embodiments, the service area of the corresponding type of satellite terminal is defined based on the generated service area map in step 300, including steps 310-320 (not shown in the drawings).

[0056] In step 310, a version number of the service area map is generated, and a forward carrier signal is generated based on the version number.

[0057] In step 320, the forward carrier signal is sent to the satellite terminal of the terminal type through a preset broadcast channel, so that the satellite terminal of the terminal type receives the forward carrier signal, and in response to the version number in the forward carrier signal being inconsistent with the version number of the locally saved service area map, the satellite terminal of the terminal type updates the locally saved service area map.

[0058] The satellite terminal of the terminal type monitors the current terminal position and matches the current terminal position with the updated service area map to determine the service state corresponding to the current terminal position according to the matching result, and the terminal service state is used to define the service area where the current terminal position is located.

[0059] In some embodiments, the version number of the service area map can be generated based on certain rules, which is used to distinguish the service area maps generated by the same type of satellite terminal at different time periods. The forward carrier signal is generated based on the version number of the service area map, and the forward carrier signal is sent to the satellite terminal through a preset broadcast channel.

[0060] In some embodiments, the gateway station imports the generated service area map into the satellite network management system to form a service area template of the user, establishes a terminal service area strategy, and associates the service area template and the available satellite beam template. The gateway station periodically broadcasts the version number of the service area map through the forward carrier, and when the satellite terminal of the corresponding type is normally powered on, the satellite terminal receives the forward carrier sent by the gateway station before entering the network. When the version number of the service area map changes, the satellite terminal enters the network to obtain the new version of the service area map and updates the local storage. The satellite terminal monitors the geographic position information of the terminal in real time, and judges the terminal service state based on the updated service area map to realize the definition of the service area.

[0061] Specifically, after receiving the forward carrier signal, the satellite terminal compares the version number of the service area map in the forward carrier signal with the version number of the locally saved service area map, confirms whether they are consistent, and if not, the satellite terminal accesses the network to obtain the service area map corresponding to the version number in the forward carrier signal. The satellite terminal monitors the local geographic information in real time, determines the terminal position, and matches the terminal position with the service area map to determine which service area the terminal is currently in, and determines the current terminal service state according to the matching result. The terminal service state is used to limit the service area where the current terminal position is located, and the terminal service state is determined by the limiting conditions marked by the service area where the current terminal position is located.

[0062] In one embodiment, optionally, according to the matching result of the current terminal position and the service area map, if the current terminal position is in the dormant area, the terminal service state is the forbidden access state, that is, the satellite terminal is in the state of forbidden access at the current position, only listens to the forward data, and does not perform the access process; optionally, according to the matching result of the current terminal position and the service area map, if the current terminal position is in the silent area, the terminal service state is the communication state of allowed access but forbidden service, that is, the satellite terminal can normally access the network at the current position, but is forbidden to perform service communication, can establish a management channel and receive one-way downlink data, but cannot start the local uplink service; optionally, according to the matching result of the current terminal position and the service area map, if the current terminal position is in the service area, the terminal service state is the communication state of allowed access and allowed service, that is, the satellite terminal can normally access the network and can perform two-way service communication, and at the current position, the satellite terminal marks the committed information rate CIR and the maximum information rate MIR belonging to it, and can establish a management channel for two-way service communication.

[0063] Further, in step 300, limiting the service area of the satellite terminal based on the service area map can further include steps 301-302 (not shown in the drawings).

[0064] Step 301, if any target terminal of the terminal type is in the target service area in the service area map, the limiting conditions marked by the target service area are obtained.

[0065] Step 302, according to the committed information rate and the highest information rate in the limiting conditions, the target terminal is rate-limited and resource-scheduled in the target service area.

[0066] If the target terminal under any terminal type is in the target service area in the service area map, the target service area calibration limiting condition is obtained, and the target terminal is rate limited and resource scheduling allocated in the target service area according to the commitment information rate CIR and the maximum information rate MIR in the limiting condition. It is known that the satellite terminal determines the terminal service state according to the locally saved service area map. When it is determined that the current terminal position is in the service area, the management channel of the normal network access and the establishment of the two-way service communication is established. The gateway station limits the rate of the satellite terminal in the service area and allocates the resources according to the limiting condition of the service area calibration of the satellite terminal.

[0067] In one embodiment, the satellite terminal monitors the local terminal position in real time. When the satellite terminal is a mobile terminal, the real-time switching of the service area can be realized by real-time monitoring of the terminal position. Specifically, referring to FIG. 2, first, according to the limiting condition of the service area of the satellite terminal, the service area of the whole network is determined by the position information of the satellite terminal, the limiting condition of the service area is calibrated to generate a service area map. The gateway station imports the generated service area map into the network management system to form a service area template of a type of satellite terminal, and establishes a terminal service area strategy associated with the service area template and the available satellite beam template. The terminal service area strategy is used for the satellite terminal to realize the limitation and switching of the service area according to the monitored terminal position. The satellite terminal is normally powered on and receives the forward carrier. The gateway station periodically broadcasts the version number of the service area map in the forward carrier. The version number is generated when the service area map is generated. If the version number of the service area map broadcast in the forward carrier is inconsistent with the version number of the locally saved service area map, the satellite terminal obtains the latest version of the service area map and updates it to the local. The latest version of the service area map is the service area map corresponding to the version number of the forward carrier broadcast. That is, the satellite terminal obtains the latest version of the service area map to update the locally saved service area map when the version number of the service area map changes by receiving the forward carrier.

[0068] Further, the satellite terminal monitors the local terminal position in real time, and matches the terminal position with the latest version of the service area map saved locally to determine the terminal service state at the current position. According to the terminal service state, it is determined whether the current position can normally access the network, if not, it is determined that the terminal enters the dormancy area, and then through real-time position monitoring, it is determined whether the terminal position is still in the dormancy area, if the terminal position of the satellite terminal is monitored to leave the dormancy area, the current terminal position is matched with the service area map saved locally again; if the satellite terminal can normally access the network at the current position, it is determined whether the satellite terminal can normally perform business communication at the current position, if not, it is determined that the terminal enters the silence area; when the satellite terminal is in the silence area, through real-time position monitoring, it is determined whether the terminal position is still in the silence area, if the terminal position of the satellite terminal is monitored to leave the silence area, the current terminal position is matched with the service area map saved locally again; if the satellite terminal can normally perform business communication at the current terminal position, the gateway station limits the communication rate of the satellite terminal according to the commitment information rate CIR and the maximum information rate MIR of the area where the terminal position is located in the service area map; then through real-time position monitoring, it is determined whether the terminal is still located in the service area, if yes, the satellite terminal reports the current transmission power and other information to the gateway station, and the gateway station allocates resources for the satellite terminal according to the commitment information rate CIR and the maximum information rate MIR of the area where the satellite terminal is located, if the terminal is monitored to leave the service area, the current terminal position is matched with the service area map saved locally again.

[0069] In some embodiments, the satellite terminal determines whether the current position can normally access the network, if the satellite terminal is prohibited from accessing the network at the current position, it enters the dormancy area, that is, in this area, the satellite terminal only listens to the forward data, and does not perform the access process. In the dormancy area, the satellite terminal buffers the management business locally, including terminal logs, statistical information and reporting information, etc. The satellite terminal monitors the local terminal position in real time, and matches the terminal position with the service area map to determine whether to leave the dormancy area. If it leaves the dormancy area, it performs the access process, and reports the buffered information to the satellite gateway station, if it enters the silence area, the satellite terminal accesses the network and listens to the downlink data sent by the gateway station, but does not send backhaul data to the gateway station; if it enters the service area, the satellite terminal performs bidirectional communication with the gateway station according to the scheduling allocation resources.

[0070] In some embodiments, when the satellite terminal determines that the current location can normally access the network but prohibits business communication, the satellite terminal enters a silent zone, i.e., in the area, the satellite terminal can normally access the network and can establish a management channel to receive one-way downlink business data, but cannot start the local transmission of uplink business. The satellite terminal monitors the local terminal location in real time and matches it with the service area map to determine whether to leave the silent zone. If the satellite terminal enters the dormant zone, the satellite terminal logs out of the network; if the satellite terminal enters the service area, the terminal performs two-way communication with the gateway according to the resource allocation of the schedule.

[0071] In some embodiments, when the satellite terminal determines that the current location can normally access the network and can normally perform business communication, the satellite terminal enters a service area, i.e., in the area, the satellite terminal marks the committed information rate CIR and the maximum information rate MIR, and can establish a management channel to perform two-way business communication. The satellite terminal monitors the local terminal location in real time and matches it with the service area map to determine whether to leave the service area. If the satellite terminal enters the silent zone, the satellite terminal accesses the network to listen to the downlink data sent by the gateway, but does not send backhaul data to the gateway; if the satellite terminal enters the dormant zone, the satellite terminal logs out of the network.

[0072] In some embodiments, in step 100, the limiting conditions corresponding to any terminal type are obtained, including the following steps (not shown in the drawings).

[0073] In step 110, a beam map corresponding to the location information is obtained, wherein the beam map is used to determine the signal coverage capability of the satellite terminal of the terminal type at the location.

[0074] In step 120, the limiting conditions corresponding to the terminal type are determined according to the beam map.

[0075] In some embodiments, a beam map corresponding to the position information of a satellite terminal of any terminal type is acquired, the beam map being used to determine the signal coverage capability at the position where the satellite terminal of the terminal type is located, and a limitation condition corresponding to the terminal type is determined according to the beam map. The beam map is composed of a point beam EIRP (Equivalent Isotropically Radiated Power) coverage map of a high-throughput satellite. A ground contour is formed by connecting points with the same EIRP value, and the contour is generally a closed curve. The EIRP coverage map is composed of ground area coverage surfaces of contours with smaller values surrounded by contours with larger values, as shown by the dashed line in FIG. 3. The beam map is determined by satellite indicators and is a fixed parameter in the entire network, and can determine the signal coverage capability at the geographical position where the satellite terminal is located. The service area map is generated based on the beam map and the limitation of specific service conditions for terminals of the same type. The service area map composed of a closed area surrounded by one or more contours is customizable by a user. A group of related service areas is defined as a service area group (SA Group), which is imported into the system by the network management system as part of the service area map. The service areas in the service area map do not need to be adjacent, and if multiple contours are used to define the service areas, the contours do not need to be continuous. Different service areas can be defined as different service conditions (the service conditions include silence, dormancy, commitment information rate CIR, and maximum information rate MIR), as shown in FIG. 3. A service area map can include multiple service areas such as SA1 to SA6, each service area is located in a respective EIRP coverage surface, and each service area can define independent service conditions.

[0076] In some embodiments, after the service area map is generated by marking the circled service area based on the limitation condition in step 200, the following steps 201-202 (not shown in the drawings) can be further included.

[0077] In step 201, a zone group type corresponding to a service area group in the service area map is determined. The zone group type includes a private zone group, a public zone group, and a global zone group.

[0078] In some embodiments, the service area map corresponding to the private zone group is used for subscription by a single user, the service area map corresponding to the public zone group is used for subscription by multiple users, and the service area map corresponding to the global zone group is used for subscription by all users.

[0079] After generating the service area map, the service area group in the service area map can be further determined to belong to a zone group type, including a private zone group, a public zone group and a global zone group. The service area map corresponding to the private zone group is used for a single user subscription, the service area map corresponding to the public zone group is used for multiple user subscriptions, and the service area map corresponding to the global zone group is used for all user subscriptions.

[0080] In some embodiments, the service area group is a group of service areas, used to represent the geographical range area of creating service areas. Each service area group defines a service area map. The service provider can subscribe to a private service area group for a user, or define a public service area group for multiple users. If all users can subscribe to a service area group, it is called a global service area group.

[0081] For different types of satellite terminal corresponding service area map, there can be multiple service area maps covering the same geographical area, allowing the same geographical area to support multiple different service users, and different users providing services in independently defined service areas. For example, in FIG. 4, the same geographical area is represented by two service area groups (which are represented by different service area maps). On the left side of FIG. 4, the geographical area is represented by one service area, supporting a single-service-condition service area, representing the same type of satellite terminal in the geographical area with the same defined conditions. On the right side of FIG. 4, the same geographical area is divided into four service areas, each of which can independently define the service defined conditions, forming a multi-service-condition service area, representing different areas in the geographical area with different defined conditions for the same type of satellite terminal.

[0082] In this embodiment, the service area of the entire network is circled according to the position information of the satellite terminal, a service area map defines the service defined conditions of a type of satellite terminal in different areas, and the service type and service level of different geographical position areas are uniformly defined for the terminal user group on the service area map, and they are periodically issued to the satellite terminal. The satellite terminal locally determines the service state to realize the limitation of the service area of the current position, simplifies the interaction process between the satellite terminal and the gateway, saves the satellite bandwidth resources, can meet the service needs of the terminal user in different geographical areas, and at the same time provides expansion capability for subsequent special geographical scene services.

[0083] Further, the satellite terminal receives a forward carrier with a service area map version number before entering the network, and when the version number of the service area map changes, the satellite terminal enters the network to obtain a new version of the service area map and updates the saved local version. The satellite terminal matches the monitored local terminal position with the updated service area map to determine the terminal service state at the current position. This solves the error of the terminal entering the network when the service state of the position where the satellite terminal is located changes, but the terminal does not obtain the updated service area map, thereby ensuring that the satellite terminal obtains the latest service area map when powered on, and automatically performs communication service judgment, avoiding the first access service error caused by the satellite terminal needing to enter the network to obtain a new version of the service area map.

[0084] Further, the service area map can be specified as a private service area group subscribed by a user, or a public service area group subscribed by multiple users, or a global service area group that can be subscribed by all users. The service area map is in the form of a template for user subscription, which is simple and clear. At the same time, multiple service area maps can cover the same geographical area at the same time, allowing the same geographical area to support multiple different types of services, and the same geographical area can create multiple different service area maps. Multiple service area maps corresponding to the same geographical area provide services to different users within independently defined service areas, which is conducive to comprehensive coverage of user scenarios.
