Description

Technical Field

[0001] The embodiments of the present application relate to the field of wireless mobile communication technology, and in particular, to a satellite communication method, a satellite base station, a satellite communication device and a system. Background Art

[0002] In the existing cellular communication system, the user equipment (UE) is connected to the base station through a wireless interface, and the base station is connected to the core network through optical fiber. Compared with the wireless interface, the transmission of the optical fiber interface is very reliable and has a large transmission capacity, so the optimization of the existing cellular communication system is mainly focused on the wireless interface. However, once a natural disaster occurs, such as an earthquake or flood, the optical fiber interface is easily damaged. In this case, a backpack satellite base station is very necessary. The backpack satellite base station is connected to the satellite through a wireless interface, and the satellite is connected to the core network equipment on the ground, thereby realizing the communication service of the UE.

[0003] Since the capabilities of various user equipments are different, when the UE sends a service request to the core network equipment through the base station, the base station needs to obtain the user equipment capability information and configure the wireless parameters according to the user equipment capability information to establish a service connection between the UE and the core network equipment.

[0004] In the prior art, the core network equipment usually provides user equipment capability information to the base station. This method is applicable to ground base stations because the ground base stations and the core network equipment are connected by optical fiber, and the transmission cost is low. However, for backpack satellite base stations, the core network equipment needs to provide UE capability information to the backpack satellite base station through a satellite link, and the transmission overhead is too expensive.

[0044] In order to make those skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings. It should be noted that different technical features in the present application can be combined with each other without conflict.

[0045] Figure 1 is a flow chart of a satellite communication method provided by an embodiment of the present application, such as Figure 1 As shown, the satellite communication method of the present application can be described as follows.

[0046] In step S1000, a base station establishes a radio resource control (RRC) connection with a user equipment (UE).

[0047] In this embodiment, the base station is a satellite base station, for example, a backpack satellite base station, which is a satellite base station that relies on a high-throughput satellite platform as a transmission carrier and provides communication between user equipment and a satellite. The backpack satellite base station may also be referred to as a portable satellite base station or a mobile satellite base station.

[0048] Step S1100: the base station receives a service request sent by a user equipment.

[0049] After establishing an RRC connection with the backpack satellite base station, the user equipment sends a service request to the backpack satellite base station. Correspondingly, the backpack satellite base station receives the service request sent by the user equipment.

[0050] For example, the user equipment sends a service request to the backpack satellite base station through a non-access stratum (NAS) message.

[0051] Exemplarily, the service request may be a request for any service, for example, the service request may be a voice communication request, a video communication request, or a data transmission request, etc., which is not limited in this embodiment.

[0052] Step S1200: The base station adds indication information to the service request and sends the service request carrying the indication information to the core network device.

[0053] Exemplarily, the core network device is a core network element device. For example, in a 5G communication network, the core network element device may be an access and mobility management function (AMF) device.

[0054] The indication information is used to indicate the type of the currently connected or communicating base station, for example, to indicate that the currently connected base station is a backpack satellite base station so that the core network device does not send user equipment capability information to the backpack satellite base station.

[0055] For example, after the base station receives a service request sent by the user equipment through a NAS message, since the base station does not interpret or parse the NAS message, in order to indicate to the core network device that it is a backpack satellite base station, the base station can merge the data of the NAS message and the data of the indication information to obtain a new NAS message, and send the new NAS message to the core network device. For example, the base station encapsulates the data of the NAS message sent by the user equipment and the data of the indication information to obtain a new NAS message, for example, encapsulating the data of the indication information after the data of the NAS message sent by the user equipment.

[0056] The indication information may be a byte segment, for example, a byte segment of 2 bits or 4 bits. For example, byte segment = 01 indicates that the base station is a satellite base station, for example, a backpack satellite base station; byte segment = 00 indicates that the base station is a non-satellite base station, for example, an ordinary ground base station, and vice versa. Alternatively, byte segment = 1111 indicates that the base station is a satellite base station, for example, a backpack satellite base station; byte segment = 0000 indicates that the base station is a non-satellite base station, for example, an ordinary ground base station, and vice versa.

[0057] Step S1300, the base station receives a service request response sent by the core network device based on the service request carrying indication information.

[0058] When the user equipment first registers, the core network device obtains the user equipment capability information from the user equipment and stores the user equipment capability information of the user equipment. After receiving the service request, the core network device determines that the base station is a backpack satellite base station based on the indication information carried in the service request, and determines not to send the user equipment capability information of the user equipment to the backpack satellite base station. For example, the core network device will not carry the user equipment capability information of the user equipment in the service request response.

[0059] Step S1400: the base station sends a service request response to the user equipment, and sends a user equipment capability request to the user equipment.

[0060] Correspondingly, the user equipment receives the service request response and the user equipment capability request sent by the base station.

[0061] The user equipment capability request is used to instruct the user equipment to report the user equipment capability information.

[0062] For example, the time sequence in which the backpack satellite base station sends the service request response and the user equipment capability request is not limited. For example, the backpack satellite base station can send the user equipment capability request to the user equipment at the same time, before or after sending the service request response.

[0063] Step S1500: The base station receives user equipment capability information sent by the user equipment.

[0064] After receiving the user equipment capability request sent by the backpack satellite base station, the user equipment sends the user equipment capability information to the backpack satellite base station.

[0065] Exemplarily, the user equipment capability information includes UE's physical layer parameters (Phy-parameters), radio frequency parameters (RF-parameters), packet data convergence protocol parameters (PDCP-parameters), radio link control parameters (RLC-parameters) and media access control parameters (MAC-parameters). For example, the user equipment capability information may include one or more of the bandwidth, frequency band, number of antennas, number of multiple input multiple output (MIMO) layers, maximum number of data radio bearers (DRBs), cache capacity, data transmission rate, and maximum power that the user equipment can support.

[0066] After obtaining the user equipment capability information, the backpack satellite base station can configure the carrier, frequency band, data bearer, data transmission rate, measurement reporting period, measurement reporting conditions, number of antennas for data transmission, number of MIMO layers and number of ports that can be used by the user equipment according to the specific parameter information included in the user equipment capability information, so that the UE can use the configured wireless parameters to achieve data transmission.

[0067] The user equipment and the core network gateway perform data (DATA) transmission.

[0068] In this way, the backpack satellite base station can obtain the user equipment capability information from the user equipment, avoiding the core network equipment from transmitting the user equipment capability information to the backpack satellite base station through the satellite link, thereby achieving the purpose of reducing the amount of signaling transmitted by the satellite link.

[0069] After acquiring the user equipment capability information, the backpack satellite base station configures wireless parameters for the user equipment according to the user equipment capability information, and the user equipment can use the wireless configuration to transmit data.

[0070] In an embodiment of the present application, the backpack satellite base station receives a service request from a user device and adds indication information to the service request, and then sends a service request carrying the indication information to a core network device, where the indication information is used to indicate that the currently connected base station is a backpack satellite base station, so that the core network device does not send the user device capability information to the backpack satellite base station. The backpack satellite base station forwards the service request response sent by the core network device to the user device, and requests the user device capability information from the user device. The backpack satellite base station receives the user device capability information sent by the user device.

[0071] Therefore, the satellite communication method of the present application can enable the backpack-type satellite base station to obtain the user equipment capability information from the user equipment, avoiding the transmission of the user equipment capability information through the satellite link, thereby reducing the transmission overhead of the satellite link.

[0072] like Figure 2 As shown, Figure 2 The structure diagram of a satellite communication system provided in an embodiment of the present application includes a user device 10, a base station 20 and a core network device 30.

[0078] The processing unit 202 is used to add indication information to the service request, where the indication information is used to indicate that the base station 20 is a backpack satellite base station, so that the core network device 30 does not send the user equipment capability information of the user equipment 10 to the base station 20 .

[0082] The receiving unit 2011 is further configured to receive user equipment capability information of the user equipment 10 sent by the user equipment 10 based on the user equipment capability request.

[0083] For example, the user equipment 10 sends a service request to the base station 20 via a NAS message, and the receiving unit 2011 receives the NAS message.

[0084] The processing unit 202 is used to merge the data of the NAS message and the data of the indication information, for example, encapsulate them together, to obtain a new NAS message, and send the new NAS message to the core network device 30 through the sending unit 2012.

[0085] The user equipment 10 sends the user equipment capability information to the base station 20 via an RRC message. The receiving unit 2011 receives the RRC message and obtains the user equipment capability information of the user equipment 10 from the RRC message.

[0086] The processing unit 202 is further configured to configure the wireless parameters of the user equipment 10 according to the user equipment capability information, so that the user equipment 10 transmits service data to the base station 20 based on the wireless parameters.
