DETAILED DESCRIPTION

[0024] In the present disclosure, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a alone, b alone, or c alone can mean: a alone, b alone, c alone, a and b in combination, a and c in combination, b and c in combination, or a, b, and c in combination, where a, b, and c can be single or multiple. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0025] The directions or positional relationships indicated by terms such as "center", "longitudinal", "lateral", "up", "down", "left", "right", "front", and "back" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present disclosure and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present disclosure.

[0026] The terms "connected" and "connected" should be understood in a broad sense. For example, the "connected" or "connected" of a circuit structure may refer to not only a physical connection, but also an electrical connection or a signal connection. For example, it may be a direct connection, i.e. a physical connection, or it may be an indirect connection through at least one intermediate element, as long as the circuit is connected. It may also be the internal connection of two elements. In addition to signal connection through a circuit, signal connection may also refer to signal connection through a media medium, such as radio waves. For those of ordinary skill in the art, the specific meanings of the above terms in this disclosure may be understood according to specific circumstances.

[0027] See also Figure 1 , Figure 1 A schematic diagram of the structure of a communication system provided in an embodiment of the present disclosure. The communication system provided in this embodiment includes but is not limited to: user equipment (UE), a base station, a core network and an external network, wherein: Figure 1The terminal device is exemplarily shown as UE, which is understandable that it does not constitute a limitation of the present disclosure. The terminal device is connected to the base station through a wireless interface, the base station is connected to the core network through an optical fiber, and the core network can be connected to the external network through an optical fiber. Among them, the terminal device includes but is not limited to a terminal device, a terminal, a UE, a mobile station, a mobile terminal, etc. The terminal device can specifically be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, an airplane, a ship, a robot, a robotic arm, a smart home device, etc.

[0028] Compared with wireless interfaces, optical fiber interfaces have more reliable transmission and larger transmission capacity, so the optimization of communication systems mainly focuses on wireless interfaces.

[0029] However, once a natural disaster occurs, such as an earthquake or flood, the optical fiber interface is easily damaged, forming a temporary communication island. In this case, satellite base stations come into being.

[0030] See also Figure 2 , Figure 2 The structure diagram of a satellite base station-based communication system provided in an embodiment of the present disclosure includes, but is not limited to: UE, satellite base station, satellite, core network and external network. Figure 2 The terminal device is exemplarily shown as UE, but it can be understood that it does not constitute a limitation of the present disclosure. Figure 2 The communication system is compared with Figure 1 The difference lies in the connection method between the base station and the core network, that is, the satellite base station is connected to the satellite through a wireless interface, and the satellite is connected to the core network element on the ground to realize the communication service of the UE. The satellite base station can also be called a portable satellite base station or a mobile satellite base station. The satellite base station can be a backpack base station, a drone base station, a vehicle base station, etc. Figure 2 The communication system shown is Figure 1 The communication system shown in the present disclosure will Figure 1 The communication system shown is referred to as a conventional communication system.

[0031] For temporary communication islands caused by natural disasters, satellite base stations can provide temporary communication services. When the conventional communication system is repaired and normal communication services are restored, Figure 1 The communication system shown in has resumed working state, and can provide services for terminal equipment through conventional communication system. At this time, the satellite base station can stop working, and the conventional communication network can provide services for terminal equipment.

[0032] Usually, the satellite base station is stopped from service by the user manually turning off its power supply. Figure 3 This section describes the process of stopping the satellite base station.

[0033] See also Figure 3 , Figure 3 A schematic diagram of the time when a satellite base station stops working is provided in an embodiment of the present disclosure. Figure 3 shows the relationship between the working time of the satellite base station and the first base station, Figure 3 The upper horizontal line in the figure indicates the working time of the satellite base station, and the lower horizontal line indicates the working time of the first base station. After the first base station cannot provide services for the terminal device, the satellite base station replaces the first base station and temporarily provides services for the terminal device. When the first base station resumes working at the first moment, the satellite base station stops working at the second moment. During the time period from the first moment to the second moment, the first base station and the satellite base station work simultaneously.

[0034] During the period from the first moment to the second moment, for a terminal device in an idle (IDLE) state, if the frequency priority corresponding to the cell provided by the first base station is higher than the frequency priority of the cell provided by the satellite base station, the terminal device will reselect the cell provided by the first base station through cell reselection during the period from the first moment to the second moment. If the frequency priority corresponding to the cell provided by the first base station is lower than the frequency priority of the cell provided by the satellite base station, or the priorities are the same, the terminal device will not perform the cell reselection operation during the period from the first moment to the second moment, until after the second moment, when the terminal device detects that the cell of the satellite base station has no signal, and then initiates cell reselection, at which time it can reselect the cell provided by the first base station.

[0035] During the period from the first moment to the second moment, for a terminal device in a radio resource control (RRC) connection state, its mobility is usually determined by the base station. After the terminal device detects the cell provided by the first base station, it can perform a cell reselection operation. However, the cell switching process is based on the measurement report, and it cannot guarantee that all connected terminal devices will meet the switching conditions, especially for terminal devices close to the satellite base station, which measure a strong signal from the satellite base station, and therefore will not trigger the switching process.

[0036] In a possible implementation, for a terminal device that has established an RRC connection with a satellite base station, the satellite base station can release it to an idle state. At the second moment, the satellite base station turns off its own power supply, and the terminal device can select the cell provided by the first base station through a cell reselection operation to initiate a connection. However, this will cause service interruption of the terminal device.

[0037] In another possible implementation, after the satellite base station obtains that the first base station has resumed working status, it can reduce the frequency priority of the cell provided by itself to a level lower than the frequency priority of the cell provided by the first base station, and the terminal device in the idle state can automatically perform a cell reselection operation and select the cell provided by the first base station. The satellite base station sends a switching command carrying the connection information of the first base station to the first terminal device that has established a connection with the satellite base station. The first terminal device establishes a connection with the first base station based on the connection information of the first base station, so that the first terminal device implements the cell reselection operation without causing the terminal device service to be interrupted, so that the user of the terminal device is unaware of the cell reselection process. After the conventional base station resumes working status, the satellite base station can automatically transfer the terminal device to the cell provided by the conventional base station while ensuring that the terminal device service is not interrupted, and turn off the power supply by itself, thereby reducing manual operations and improving the working efficiency of the communication system.

[0038] The technical solution provided by the present disclosure is described in detail below with specific embodiments.

[0039] See also Figure 4 , Figure 4 The interactive schematic diagram of a method for stopping a satellite base station from working provided by an embodiment of the present disclosure. Figure 4 As shown, the satellite base station in this embodiment can be the above Figure 2 The satellite base station in the embodiment shown. The terminal device in this embodiment can be the above Figure 2 The terminal device in the embodiment shown, wherein the terminal device in the connected state is referred to as the first terminal device in this embodiment, and the terminal device in the idle state is referred to as the third terminal device in this embodiment. The method provided in this embodiment may include the following steps 401-403.

[0040] Step 401: After determining that the first base station has resumed working, the satellite base station reduces the frequency priority of the cell provided by the satellite base station to the first level.

[0041] Among them, the first level is lower than the frequency priority provided by the first base station.

[0042] Further, the first level may be the lowest level of frequency priority.

[0043] Step 402: After detecting that the frequency priority of the cell of the satellite base station where the third terminal device is currently located is reduced, the third terminal device starts a cell measurement operation.

[0044] Step 403: If the third terminal device measures the cell provided by the first base station, a cell reselection operation is performed.

[0045] In this embodiment, after the first base station is unable to provide services to the terminal device due to its own failure or interruption of communication with the core network device, a satellite base station can be set near the first base station so that the satellite base station temporarily replaces the first base station to continue to provide services to the terminal device until the satellite base station determines that the first base station has resumed working state, and then the satellite base station can start the shutdown process. The shutdown process of the satellite base station refers to the processing performed by the satellite base station after determining that the first base station has resumed working state until the satellite base station turns off the power supply.

[0046] Since the third terminal device in an idle state usually selects a cell with a higher frequency priority, the satellite base station actively reduces the frequency priority of the cell provided by itself to the first level lower than the first base station after determining that the first base station has resumed working. After detecting that the frequency priority of its own cell has been reduced, the third terminal device currently in an idle state automatically starts a cell measurement operation to detect other cells. Since the first base station has resumed working, the third terminal device can detect the cell provided by the first base station at this time, and determines that the frequency priority of the cell provided by the first base station is higher than the frequency priority of its own cell, then the third terminal device performs a cell reselection operation to place itself in the cell provided by the first base station.

[0047] Step 404: After determining that the first base station has resumed working status, the satellite base station sends a switching command to the first terminal device connected to the satellite base station.

[0048] The handover command includes connection information of the first base station. The connection information of the first base station refers to relevant information required for the terminal device to connect to the first base station. The handover command is used to instruct the first terminal device to establish a connection with the first base station according to the connection information of the first base station. The establishment of a connection with the first base station mentioned in this embodiment may be an establishment of an RRC connection with the first base station.

[0049] Furthermore, the connection information of the first base station may include at least one of the following items: a physical cell identifier (PCI) of at least one cell provided by the first base station, a frequency of at least one cell provided by the first base station, and identification information (Cell ID) of at least one cell provided by the first base station.

[0050] Furthermore, the connection information of the first base station may also include: bandwidth information of at least one cell provided by the first base station.

[0051] It should be noted that there is no order in which step 401 and step 404 are executed. Step 401 may be executed first and then step 404; step 404 may be executed first and then step 401; or step 401 and step 404 may be executed simultaneously. The present disclosure does not limit the order in which step 401 and step 404 are executed.

[0052] Step 405: The first terminal device establishes a connection with the first base station based on the connection information of the first base station.

[0053] It should be noted that the execution of step 402 and step 403 is independent of the execution of step 404 and step 405, and they do not affect each other during the execution process.

[0054] In this embodiment, after the satellite base station starts the shutdown process, for the first terminal device connected to the satellite base station, that is, the terminal device in the RRC connection state in the cell provided by the satellite base station, the satellite base station sends a switching command carrying the connection information of the first base station to the first terminal device. The first terminal device responds to the switching command and searches for the cell provided by the first base station according to the connection information of the first base station carried in the switching command, and establishes a connection with the first base station. The first terminal device implements the cell reselection operation. After establishing the RRC connection with the first base station, the first terminal device is in the cell provided by the first base station. Exemplarily, after establishing the RRC connection with the first base station, the data radio bearer (DRB) is restored through the first base station, and the first terminal can provide services through the first base station, thereby achieving uninterrupted services for the first terminal.

[0055] Step 406: After determining that no terminal device is currently connected, the satellite base station turns off the power supply.

[0056] After the satellite base station determines that there is no terminal device currently connected, it can turn off its own power supply.

[0057] In this embodiment, after the satellite base station obtains that the first base station has resumed working status, it can reduce the frequency priority of the cell provided by itself to a level lower than the frequency priority of the cell provided by the first base station, and the terminal device in the idle state can automatically perform a cell reselection operation and select the cell provided by the first base station. The satellite base station sends a switching command carrying the connection information of the first base station to the first terminal device that has established a connection with the satellite base station. The first terminal device establishes a connection with the first base station based on the connection information of the first base station, so that the first terminal device implements the cell reselection operation without causing the terminal device service to be interrupted, so that the user of the terminal device is unaware of the cell reselection process. After the conventional base station resumes working status, the satellite base station can automatically transfer the terminal device to the cell provided by the conventional base station while ensuring that the terminal device service is not interrupted, and turn off the power supply by itself, thereby reducing manual operations and improving the working efficiency of the communication system.

[0058] In some scenarios, the satellite base station can determine that the first base station has resumed working status in a variety of ways. Four possible implementations are exemplarily described below.

[0059] In a possible implementation, before step 401, it can be determined through the following step 4001 whether the first base station resumes working status.

[0060] Step 4001: The satellite base station receives a first work resumption notification sent by a network management platform and determines that the first base station has resumed working.

[0061] The first resumption notification includes connection information of the first base station.

[0062] Among them, the network management platform can monitor the network status, troubleshoot, optimize performance, manage security, etc. in real time. Usually, the network management platform can manage the base stations in the communication system.

[0063] In this embodiment, if the first base station resumes working, the network management platform may send a first work resumption notification carrying connection information of the first base station to the satellite base station. The satellite base station may send a switching command carrying connection information of the first base station to the first terminal.

[0064] In another possible implementation, before step 401, it can be determined through the following step 4002 whether the first base station resumes the working state.

[0065] Step 4002: The satellite base station receives a second work resumption notification sent by the first base station, and determines that the first base station has resumed working.

[0066] The second resumption notification includes connection information of the first base station.

[0067] In this embodiment, if the first base station resumes working, the first base station may send a first work resumption notification carrying connection information of the first base station to the satellite base station. The satellite base station may send a handover command carrying connection information of the first base station to the first terminal.

[0068] In another possible implementation, before step 401, it can be determined through the following step 4003 whether the first base station resumes the working state.

[0069] Step 4003: The satellite base station receives the third resumption of work notification sent by the first terminal device and determines that the first base station has resumed working status.

[0070] The third resumption work notification includes connection information of the first base station.

[0071] The first terminal device may be any terminal device connected to a satellite base station.

[0072] In this embodiment, the satellite base station may configure one or more first terminal devices to perform a measurement operation, and after measuring the wireless signals of other cells, the satellite base station may be notified. If the first base station resumes working, and the first terminal device performing the measurement operation can measure the cell provided by the first base station, the first terminal device performing the measurement operation may send a first resumption of work notification carrying the connection information of the first base station to the satellite base station. The satellite base station may send a handover command carrying the connection information of the first base station to all first terminals connected thereto.

[0073] In another possible implementation, before step 401, it can be determined through the following step 4004 whether the first base station resumes the working state.

[0074] Step 4004: The satellite base station receives the fourth work resumption notification input by the user and determines that the first base station has resumed working status.

[0075] The fourth resumption of work notification includes connection information of the first base station.

[0076] In this embodiment, the satellite base station may include an interactive interface or an interactive module for receiving a fourth resumption of work notification. If the first base station resumes working status, the user may input a fourth resumption of work notification containing connection information of the first base station through the interactive interface or the interactive module. Exemplarily, the interactive interface may be used to connect to a peripheral such as a keyboard to receive a fourth resumption of work notification containing connection information of the first base station input by the user through the peripheral; the interactive interface may also be used to connect to a touch screen, and the touch screen may receive a fourth resumption of work notification containing connection information of the first base station input by the user, etc. The satellite base station may send a switching command carrying the connection information of the first base station to all first terminals connected thereto.

[0077] In some embodiments, see Figure 5 , Figure 5 An interactive schematic diagram of another method for stopping a satellite base station from working provided by an embodiment of the present disclosure, Figure 5 is Figure 4 On the basis of the illustrated embodiment, further, in step 406, the terminal device that is currently unconnected is determined in the following manner: After step 404, the following steps 407 and 408 may also be included.

[0078] Step 407: The satellite base station starts timing.

[0079] Step 408: If the timing duration reaches a preset duration and the satellite base station does not receive a reconnection request sent by the first terminal device, the satellite base station determines that the terminal device is not currently connected.

[0080] The preset duration is a pre-set time length. Exemplarily, the preset duration may be set according to the duration used by the terminal device for cell reselection. Usually, the preset duration may be greater than the duration used by the terminal device for cell reselection.

[0081] In one possible implementation, the satellite base station may simultaneously send a switching command to all first terminal devices and start timing. Usually, after receiving the switching command, the first terminal device attempts to establish a connection with the first base station. If the first terminal device successfully connects to the first base station, the first terminal device achieves reconnection; if the first terminal device fails to connect to the first base station, it may request to establish a connection with the satellite base station again. Therefore, when the timing duration reaches the preset duration, the satellite base station does not receive the reconnection request sent by the first terminal device, indicating that the first terminal device has established a connection with the first base station, and the satellite base station determines that it is not currently connected to the terminal device.

[0082] In another possible implementation, the satellite base station may send a switching command to all first terminal devices respectively. Since the sending time may not be exactly the same, the timing may be started each time the switching command is sent to a first terminal device. When all the timing durations reach the preset duration, the satellite base station does not receive the reconnection request sent by the first terminal device, indicating that the first terminal device has established a connection with the first base station, and the satellite base station determines that it is not currently connected to the terminal device.

[0083] In a possible implementation, the satellite base station may send a switching command to all first terminal devices respectively. Since the sending time may not be exactly the same, the timing may start after the switching command is sent to the first terminal device for the first time. When the timing duration reaches the preset duration, the satellite base station does not receive the reconnection request sent by the first terminal device, indicating that the first terminal device has established a connection with the first base station, and the satellite base station determines that it is not currently connected to the terminal device.

[0084] In this embodiment, if the satellite base station does not receive a request for reconnection from the first terminal device within a preset period of time after sending a switching command to the first terminal device, it means that the first terminal device has established a connection with the first base station, and the satellite base station determines that it is not currently connected to the terminal device. Therefore, after the conventional base station resumes working, the satellite base station automatically turns off its own power supply after ensuring that the terminal device connected to it has automatically transferred the terminal device to the cell provided by the conventional base station in a simple and easy way, and does not cause the terminal device service to be interrupted, so that the user of the terminal device is unaware of the process of cell reselection, which reduces manual operations and improves the working efficiency of the communication system.

[0085] In some scenarios, in a possible implementation of step 406, the satellite base station turns off the power after determining that the terminal device is not currently connected. In another possible implementation of step 406, after determining that the terminal device is not currently connected, the satellite base station may first broadcast the time when it is going to stop working, and then turn off the power when the time to stop working arrives. The following is a detailed description with specific embodiments.

[0086] In some embodiments, step 406 may be implemented by steps 4061 and 4062 as follows.

[0087] Step 4061: After determining that no terminal device is currently connected, the satellite base station broadcasts a stop working instruction.

[0088] The stop working instruction includes identification information of the first time or the first radio frame. It can be understood that the first time is an absolute time. The identification information of the first radio frame may include a radio frame number; or a radio frame number and a subframe number.

[0089] The stop working instruction is used to instruct the satellite base station to turn off the power at the first time or after sending the radio frame corresponding to the identification information of the first radio frame. If the stop working instruction includes the first time, the stop working instruction is used to instruct the satellite base station to turn off the power when the first time arrives.

[0090] Exemplarily, the satellite base station may broadcast the stop working instruction via system information broadcast or via application layer message broadcast.

[0091] Step 4062: When the first time arrives, or after sending the radio frame corresponding to the identification information of the first radio frame, the satellite base station turns off the power supply.

[0092] In this embodiment, after determining that no terminal device is currently connected, the satellite base station broadcasts a stop working instruction, and the terminal device that receives the stop working instruction does not need to try to establish a connection with the satellite base station. If the stop working instruction includes a first time, the stop working instruction is used to indicate that the satellite base station will turn off the power when the first time arrives. The satellite base station turns off its own power when the first time mentioned in the broadcast arrives. If the stop working instruction includes identification information of the first wireless frame, the stop working instruction is used to indicate that the satellite base station will turn off the power after sending the wireless frame corresponding to the identification information of the first wireless frame. After the terminal device receives the stop working instruction, if the identification information of the wireless frame received for the first time is consistent with the identification information of the first wireless frame, the terminal device determines that the satellite base station has stopped working.

[0093] Before the satellite base station stops working and turns off the power, the terminal devices in the system are notified, allowing the terminal devices to make better decisions on the next step, thereby improving the working efficiency of the communication system.

[0094] In some embodiments, see Figure 6 , Figure 6 An interactive schematic diagram of another method for stopping a satellite base station from working provided by an embodiment of the present disclosure, Figure 6 is Figure 4 or Figure 5 On the basis of the embodiment shown, further, the following step 409 may be included before step 404. Accordingly, this embodiment also includes step 410, and step 411 is included after step 405. It should be noted that, Figure 6 The third terminal device is not shown.

[0095] Step 409: The satellite base station sends a first message to the core network device.

[0096] Among them, the first message includes context information of a first terminal device connected to the satellite base station. The first message is used to instruct the core network device to send the context information of the first terminal device to the first base station, so that after the first base station establishes a connection with the first terminal device, it can establish a user data wireless bearer for the first terminal device based on the context information of the first terminal device.

[0097] Furthermore, in the case where the communication system is a fourth generation mobile information system (4G), the core network device may be a mobility management entity (Mobility Management Entity, ‌MME‌ for short).

[0098] Furthermore, when the communication system is the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, referred to as 5G), the core network device may be an authentication management function entity (Authentication Management Function, referred to as AMF).

[0099] Step 410: The core network device sends the context information of the first terminal device to the first base station in response to the first message.

[0100] Step 411: After establishing a connection with the first terminal device, the first base station establishes a user data radio bearer for the first terminal device based on the context information of the first terminal device.

[0101] In this embodiment, after learning that the first base station has resumed working status, the satellite base station can send context information containing the first terminal device connected to the satellite base station to the first base station through the core network device. Therefore, after the first terminal device establishes an RRC connection with the first base station, the first base station can establish a user data wireless bearer for the first terminal device based on the context information of the first terminal device, thereby ensuring that the data service of the first terminal device is not interrupted and the user of the terminal device is unaware, thereby improving the working efficiency of the communication system.

[0102] In some scenarios, after step 401, when the satellite base station needs to turn off the power supply, if there is a second terminal device trying to establish a connection with the satellite base station, the satellite base station does not establish a connection with the second terminal device, but enables the second terminal device to establish a connection with the first base station. This is described in detail with specific embodiments below.

[0103] In some embodiments, the time between step 401 and step 406 may also include the following steps 412 and 413.

[0104] Step 412: After determining that the first base station resumes working status, if the satellite base station receives a connection request sent by the second terminal device, the satellite base station sends a reselection instruction to the second terminal device.

[0105] The reselection instruction includes the connection information of the first base station. The reselection instruction is used to instruct the second terminal device to establish a connection with the first base station according to the connection information of the first base station.

[0106] It should be noted that the reselect instruction is similar to the above-mentioned switching command and will not be described in detail here.

[0107] Exemplarily, in step 412, if the satellite base station receives a connection request sent by the second terminal device, it may first determine whether the second terminal device is the first terminal device.

[0108] If the second terminal device is not the first terminal device, it means that the second terminal device is a terminal device that has not established a connection with the satellite base station before, and the satellite base station sends a reselection instruction to the second terminal device.

[0109] If the second terminal device is the first terminal device, it means that the second terminal device fails to establish a connection with the first base station, and the satellite base station may also send a reselection instruction to the second terminal device. It should be noted that in this case, the timing duration of the satellite base station needs to be restarted.

[0110] Step 413: The second terminal device establishes a connection with the first base station based on the connection information of the first base station.

[0111] In this embodiment, after the satellite base station determines that the first base station has resumed working state, and during the period from when the satellite base station automatically turns off the power supply, if the satellite base station receives a connection request from the second terminal device, since the satellite base station is about to turn off the power supply, the satellite base station does not establish a connection with the second terminal device, but sends the connection information of the first base station to the second terminal device, and the second terminal device can establish a connection with the first base station based on the connection information sent to the first base station. It is ensured that there is no connected terminal device before the satellite base station turns off the power supply, and the services of the terminal devices are not interrupted, thereby improving the working efficiency of the communication system.
