[0125] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art based on the present application belong to the protection scope of the present application.

[0126] Next, the terms appearing in the embodiments of the present application will be explained.

[0127] Communication mode of the access device: The protocol for communication between the access device and the terminal. For example, the access device is set with multiple communication modes, such as OFDM (Orthogonal Frequency Division Multiplexing), TTD, and TDM (Time Division Multiplexing). Among them, in a Non-Terrestrial Network (NTN) communication system, the access device can be a non-terrestrial network device such as a satellite, a space station, or a drone; in a terrestrial network communication system, the access device can be a terrestrial network device such as a router, a switch, or a base station.

[0128] Base station access devices such as those in a terrestrial network communication system are fixedly installed on the ground, and the terminal is in a moving state. During the communication process between the terminal and the base station, the terminal has the problem of handover across cells in the same communication mode or handover across cells in two different communication modes. The cell handover process is very mature and does not involve the problem of dynamic handover of the communication mode of the base station on the terrestrial network communication system side. In a non-terrestrial network communication system, there is only the problem of handover of the terminal across beams and across satellites caused by the movement of the access device.

[0129] However, the terrestrial landing power level limits of the access network in different regions may be different. In a communication system, especially in a non-terrestrial network communication system, due to the limitation of the terrestrial landing power level, the access device needs to adopt different communication modes when operating in different regions, and there is a problem of handover of the communication mode across regions for the access device. Different from the cell handover that occurs on the terrestrial side terminal, when to perform the handover of the communication mode across regions for the access device and the handover process across regions are a brand-new topic, and there is no existing communication system for reference.

[0130] To solve the above problems and achieve the handover of the communication mode of the access device across regions, the embodiments of the present application provide a method for handover of the communication mode of the access device. This method can be applied to devices with base station functions deployed, such as access devices or other gateways communicatively connected to the access device. This gateway can be an NTN gateway, a gateway station, or a server communicatively connected to the access device, or other network devices with base station functions deployed. The terminal is connected to the access device, and the access device is connected to the gateway. The terminal can access the data network through the access device and the gateway.

[0131] The technical solution provided by the embodiments of the present application can be applied to any communication system, such as a terrestrial network communication system and a non-terrestrial network communication system, especially applied to a non-terrestrial network communication system where the movement of the access device changes greatly, and can effectively solve the problem of handover of the communication mode of the access device across regions. The following takes the non-terrestrial network communication system as an example for illustration, which is not restrictive.

[0132] In a non-terrestrial network communication system, the gateway is deployed on the ground, such as the above-mentioned gateway station. The functions of the base station can be divided into two parts. One part of the function is deployed on the access device, and the other part of the function is deployed in the gateway. For example, the functions of the base station can be divided into the functions of the Centralized Unit (CU) and the Distributed Unit (DU). The DU is deployed on the access device, and the CU is deployed in the gateway. In this case, the above method for handover of the communication mode of the access device can be applied to the gateway or the access device.

[0133] In a non-terrestrial network communication system, the functions of the base station can also be fully deployed in the access device. For example, both the CU and the DU are deployed in the access device. In this case, the above method for switching the communication mode of the access device can be applied to the access device, which realizes the function of the gateway while realizing the access function.

[0134] As Figure 1 shown, Figure 1 FIG. 1 is a first flowchart of the method for switching the communication mode of the access device provided by the embodiment of the present application. The switching method is applied to the gateway, and the method includes the following steps.

[0135] Step S11, when reaching the first time in the preset correspondence, the gateway obtains the first relevant information of the first communication mode corresponding to the first time. The preset correspondence is the correspondence between the communication mode and the time for performing the communication mode switch, and the first communication mode is the communication mode corresponding to the first time in the preset correspondence.

[0136] Step S12, the gateway sends the first relevant information to the access device.

[0137] In the technical solution provided by the embodiment of the present application, the time for switching the communication mode and the relevant information of the communication mode in different regions are configured. When the access device operates to a new region and reaches the time for switching the communication mode of the region, such as the first time, the gateway then sends the first relevant information of the first communication mode to the access device. In this way, the access device can switch to the first communication mode according to the first relevant information, realizing the cross-region switching of the communication mode of the access device.

[0138] In the above step S11, the gateway can estimate the time when the access device operates to different regions. Here, the time when the access device operates to a region can be used as the time for switching to the communication mode of the region, or the time for switching to the communication mode of the region can also be the time obtained after specifying a time in advance for the time when the access device operates to a region, and this is not limited. The specified time is the time required for the communication mode switch. In addition, multiple regional communication modes can be set in the gateway. Based on this, the correspondence between the communication mode for switching each region and the time for switching the communication mode of each region can be obtained. The correspondence can include but is not limited to the identifier of the access device, the number of beams for switching the communication mode, the identifier of the beam on the access device where the communication mode switch occurs, the time for the beam to switch the communication mode, the number of times the beam switches the communication mode, the identifier of the target switching communication mode of the beam, etc., where the target switching communication mode is the communication mode that the beam is to be switched to.

[0139] The gateway can monitor the time for executing the switching of each communication mode based on the above-mentioned preset corresponding relationship. When it monitors that the time for executing the switching of a communication mode is reached, and this communication mode is the first communication mode, at the first time for executing the switching of a communication mode, the gateway obtains the relevant information of this first communication mode, that is, the first relevant information.

[0140] In the embodiments of the present application, the relevant information of the communication mode is the information that can enable the access device to accurately switch to this communication mode. The relevant information of the communication mode may include, but is not limited to: the identifier of the access device, the identifier of the communication mode, the identifier of the beam for switching to this communication mode, etc. The relevant information of the communication mode may also include the time for the beam to switch to this communication mode, the number of beams for switching the communication mode, etc. In the same communication mode, the time for different beams to switch to this communication mode may be the same or different. The number of the determined first communication modes may be one or more, and the number of beams for switching to this communication mode may be one or more. Based on the relevant information of the communication mode, the above-mentioned first relevant information may include at least one of the following information: the identifier of the first communication mode, the identifier of the beam for switching to the first communication mode, etc.

[0141] In the embodiments of the present application, the gateway can obtain the communication modes of different regions and the time for switching to the communication modes of different regions through dynamic calculation, that is, determine the corresponding relationship between the above-mentioned communication mode and the time for executing the switching.

[0142] For example, the gateway obtains the earth position of the access device in real time, and determines the region where the current access device is located and the communication mode of the region where the current access device is located according to information such as the earth position of the access device, the beam direction pattern, the inter-beam frequency interference analysis, and the earth coverage. And when it determines that there is a cross-region situation, it determines the time (such as the above-mentioned first time) for reaching the switching of the communication mode (such as the above-mentioned first communication mode), and further obtains the first relevant information of the first communication mode.

[0143] The gateway obtains the communication modes of different regions and the time for switching to the communication modes of different regions through dynamic calculation, which is convenient for accurately controlling the switching of the communication mode of the access device.

[0144] In the embodiments of the present application, the gateway can also obtain the corresponding relationship between the relevant information of the communication mode and the time for executing the switching through static task planning. For example, the gateway can determine the corresponding relationship between the communication mode and the time for executing the switching according to information such as the operation trajectory information of the access device, the beam direction pattern, the inter-beam frequency interference analysis, and the earth coverage information, and store the obtained corresponding relationship between the communication mode and the time for executing the switching. Among them, the operation trajectory information may be ephemeris information.

[0145] In this case, the first time is the time in the preset correspondence; the first communication mode is the communication mode corresponding to the first time in the preset correspondence, and the first relevant information is the relevant information of the first communication mode.

[0146] In the embodiments of the present application, the correspondence between the communication mode and the time for performing the handover can be stored in the form of a list or in the form of a database, and this is not limited. Taking the storage of the correspondence between the communication mode and the time for performing the handover in the form of a list as an example, for ease of understanding, the list storing the correspondence between the communication mode and the time for performing the handover is hereinafter simply referred to as the cross-region mode handover list. In the embodiments of the present application, before entering a beam handover period, the gateway can design a mode handover algorithm in advance according to information such as the running trajectory information, the beam pattern, the earth coverage information, and the inter-beam frequency interference analysis, and perform static planning of the cross-region mode handover list within the beam handover period in advance to generate the cross-region mode handover list, such as Figure 2 the schematic diagram of generating the cross-region mode handover list shown. At this time, the mode handover list may include information such as the number of beams for which each access device performs mode handover, the number of times of mode handover for each beam, the time for switching the communication mode, and the switched communication mode, such as Figure 3 a schematic diagram of a cross-region mode handover list shown, including access device identifier, number of switched beams, beam identifier 0 - beam identifier N, number of mode handovers, time 1 - time M or time 1 - time N, mode 1 - mode M or mode 1 - mode N, reserved field, etc. Mode 1 - mode M or mode 1 - mode N is the switched communication mode, time 1 - time M or time 1 - time N is the time for switching the communication mode, the number of mode handovers is the number of times of mode handover for a beam, and the number of switched beams is the number of beams for which mode handover occurs. The above beam handover period can be set according to actual needs. For example, the beam handover period can be 1 hour, 1 day, 1 week, etc., and this is not limited. The number of rows of the cross-region mode handover list and the length of each row of information can be set according to actual needs.

[0147] Based on the cross-region mode handover list obtained through static planning, when the first time arrives, the gateway can quickly obtain the communication mode to be switched from the cross-region mode handover list, and then obtain the relevant information of the communication mode to be switched, without the need for the access device to perform complex beam mode handover calculations according to information such as the earth position of the access device, the beam pattern, the inter-beam frequency interference analysis, and the earth coverage, which simplifies the processing of the access device load, reduces the burden of the access device load, improves the efficiency of mode handover, and meets the communication requirements of different regions.

[0148] In the above step S12, after the gateway obtains the first relevant information, it sends the first relevant information to the access device. After receiving the first relevant information, the access device can, according to the first relevant information, switch the corresponding beam to the first communication mode, realizing the cross-region communication mode switching of the access device.

[0149] In some embodiments, the gateway can notify the access device of the first relevant information through a base station (such as gNB) parameter configuration update message of the air-ground interface, that is, notify the access device which beams carry out mode switching and the communication mode after switching. After the access device payload receives the configuration update message, it feeds back to the gateway, and then the gateway and the access device payload switch to the new communication mode to work at the same time. For example, the gateway carries the first relevant information in the first message and sends it to the access device. After the access device completes the communication mode switching, it sends a second message to the gateway; the gateway receives the second message sent by the access device, and the second message indicates that the communication mode switching is completed. Among them, the air-ground interface is the interface connecting the gateway and the access device, such as the satellite-ground interface.

[0150] Among them, the first message can be a base station configuration update message, the second message can be a base station configuration update confirmation message, and the first message and the second message can also be other base station parameter configuration update messages of the air-ground interface, which are not limited thereto.

[0151] In some embodiments, as Figure 4 shown, there is also provided a method for switching the communication mode of an access device, which can include the following steps.

[0152] Step S41, when the second time arrives, the gateway instructs the first terminal to perform radio resource control connection reconfiguration according to the first communication mode; wherein, the second time is earlier than the first time, and the difference between the second time and the first time is a preset time difference.

[0153] Step S42, when the first time in the preset correspondence arrives, the gateway obtains the first relevant information of the first communication mode corresponding to the first time. The preset correspondence is the correspondence between the communication mode and the time for performing the communication mode switching, and the first communication mode is the communication mode corresponding to the first time in the preset correspondence. It is the same as the above step S11.

[0154] Step S43, the gateway sends the first relevant information to the access device. It is the same as the above step S12.

[0155] In the technical solution provided by the embodiment of the present application, at a second time before the first time to switch the communication mode of the access device, the first terminal is instructed to perform radio resource control connection reconfiguration according to the first communication mode. In this way, when the first time arrives and the access device switches to the first communication mode, the first terminal can quickly reconnect to the access device in the first communication mode, ensuring the service continuity of the terminal in the connected state, solving the problems in the engineering application of communication systems such as non-terrestrial network communication systems, and meeting the communication requirements of communication systems such as non-terrestrial network communication systems in complex earth coverage scenarios.

[0156] In the above step S41, the first terminal can be any terminal in the connected state with the access device. The preset time difference can be set according to actual needs. The RRC connection reconfiguration information can include but is not limited to the first communication mode, public information, dedicated time-frequency resources, etc.

[0157] Before the mode switch, the gateway can notify the first terminal of the switched first communication mode through the access device, so that the first terminal performs radio resource control (RRC) connection reconfiguration according to the first communication mode and accesses the beam of the first communication mode, avoiding service interruption of the first terminal.

[0158] In some embodiments, the above step S41 can be: the gateway sends a third message to the access device, and the third message carries a fourth message; the access device sends the fourth message to the first terminal, and the fourth message carries the reconfiguration information of the RRC connection; the gateway receives a fifth message sent by the access device, and the fifth message is a response message to the third message.

[0159] In the embodiment of the present application, the gateway instructs the first terminal to perform RRC connection reconfiguration according to the first communication mode through base station parameter configuration update messages (such as the above third message, fourth message, fifth message, etc.) of the air-ground interface. Among them, the third message can be a terminal context modification request message, the fourth message can be an RRC connection reconfiguration message, and the fifth message can be a terminal context modification response message. The third message, the fourth message, and the fifth message can also be other base station parameter configuration update messages of the air-ground interface, which are not limited thereto.

[0160] In some embodiments, as Figure 5 shown, a method for switching the communication mode of an access device is further provided, which may include the following steps.

[0161] Step S51, when the second time arrives, the gateway instructs the first terminal to perform RRC connection reconfiguration according to the first communication mode; wherein, the second time is earlier than the first time, and the difference between the second time and the first time is a preset time difference. It is the same as the above step S41.

[0162] Step S52, when the first time in the preset correspondence is reached, the gateway obtains the first relevant information of the first communication mode corresponding to the first time. The preset correspondence is the correspondence between the communication mode and the time for performing communication mode switching. The first communication mode is the communication mode corresponding to the first time in the preset correspondence. This is the same as step S11 above.

[0163] Step S53, the gateway sends the first relevant information to the access device. This is the same as step S12 above.

[0164] Step S54, the gateway receives the sixth message sent by the access device. The sixth message carries the seventh message sent by the first terminal, and the seventh message indicates that the RRC connection reconfiguration is completed.

[0165] In the embodiment of the present application, the gateway indicates that the RRC connection reconfiguration is completed through the base station parameter configuration update message (such as the above-mentioned sixth message, seventh message, etc.) of the air-ground interface. The sixth message may be an RRC message transmission message, the seventh message may be an RRC connection reconfiguration completion message, and the sixth message and the seventh message may also be other base station parameter configuration update messages of the air-ground interface, which are not limited thereto.

[0166] The seventh message may be a message sent by the first terminal after the access device switches to the first communication mode. The sixth message is a message sent by the access device after receiving the seventh message.

[0167] The first terminal may configure a specified duration, and after the specified duration of receiving the fourth message, the first terminal sends the seventh message to the access device. The specified duration may be determined according to the time required for communication mode switching.

[0168] To ensure timely access to the access device after switching the communication mode and ensure service continuity, after the access device switches to the first communication mode, it may send synchronization and system broadcast messages. Both the first terminal and the gateway can receive the synchronization and system broadcast messages. After receiving the synchronization and system broadcast messages, the first terminal sends the seventh message to the access device.

[0169] In the technical solution provided by the embodiment of the present application, after the access device switches to the first communication mode, the terminal then sends the seventh message to access the access device in the switched first communication mode, completing the RRC connection reconfiguration and ensuring service continuity.

[0170] In the embodiment of the present application, for a terminal in the idle state, when the terminal needs to access the access device in the switched first communication mode and work in the first communication mode, the terminal performs a terminal mode selection process to camp on the first communication mode; in addition, the terminal starts the access and initial registration processes and works in the first communication mode.

[0171] The following combines Figure 6 with the signaling diagram of the handover process of the access device communication mode shown in the figure, and details the handover method of the access device communication mode provided by the embodiments of the present application. Figure 6 Among them, part of the functions of the base station are deployed on the access device, and another part of the functions of the base station are deployed on the gateway. The terminal (UE), access device, and gateway operate in communication mode 1. T1 is earlier than T2, and T1 - T2 is a preset time difference.

[0172] Step S61, the gateway detects whether T1 is reached; if so, step S62 is executed; if not, step S61 is continued to be executed.

[0173] Step S62, the gateway sends a terminal context modification request message to the access device, and the terminal context modification request message carries an RRC connection reconfiguration message. The RRC connection reconfiguration message includes communication mode 2, public information, and dedicated time-frequency resources.

[0174] Among them, the terminal context modification request message can be a UE Context Modification Request message, and the RRC connection reconfiguration message can be an RRC Connection Reconfiguration message.

[0175] Step S63, the access device sends an RRC connection reconfiguration message to the UE.

[0176] After the UE receives the RRC connection reconfiguration message, it configures the time-frequency resources corresponding to communication mode 2 according to the communication mode 2, public information, and dedicated time-frequency resources included in the RRC connection reconfiguration message.

[0177] Step S64, the access device sends a terminal context modification response message to the gateway.

[0178] Among them, the terminal context modification response message can be a UE Context Modification Response message.

[0179] Step S65, the gateway detects whether T2 is reached; if so, step S66 is executed; if not, step S65 is continued to be executed.

[0180] Step S66, the gateway sends a base station configuration update message to the access device.

[0181] Among them, the base station configuration update message may include information related to communication mode 2, such as the identifier of communication mode 2, the identifier of the beam switched to communication mode 2, the handover time T2, the number of times of beam handover communication mode, etc. The base station configuration update message can be a gNB Configure Update message.

[0182] Step S67, the access device sends a base station configuration update confirmation message to the gateway and switches from communication mode 1 to communication mode 2.

[0183] Among them, the base station configuration update confirmation message may carry a communication mode 2 switching completion message. The base station configuration update confirmation message may be a gNB Configure Update Ack message.

[0184] Step S68, the access device sends synchronization and system broadcast messages.

[0185] After the gateway and the UE receive the synchronization and system broadcast messages, it is confirmed that one or more beams of the access device are switched to communication mode 2.

[0186] Step S69, the connected terminal sends an RRC connection reconfiguration complete message to the access device.

[0187] Among them, the RRC connection reconfiguration complete message may be an RRC Connection ReconfigurationComplete message.

[0188] Step S610, the access device sends an RRC message transfer message to the gateway.

[0189] Among them, the RRC message transfer message carries the RRC connection reconfiguration complete message, and the RRC message transfer message may be a ULRRC Message Transfer message.

[0190] At this time, the connected terminal can work in communication mode 2 and communicate with the access device using communication mode 2.

[0191] For an idle terminal, after the access device and the gateway work in communication mode 2, the following steps are executed.

[0192] A. The idle terminal enters the terminal mode selection process and camps on communication mode 2.

[0193] The idle terminal can select the communication mode to camp on from multiple accessible communication modes. These multiple communication modes may come from different beams of the same access device or different beams of different access devices, and there is no limitation on this.

[0194] B. The idle terminal starts the initial registration process and works in communication mode 2.

[0195] In the technical solution provided by the embodiment of the present application, the time for switching the communication mode and the relevant information of the communication modes in different regions are configured. When the access device moves to a new region and reaches the time for switching the communication mode of this region, such as the first time, the gateway then sends the first relevant information of the first communication mode to the access device. In this way, the access device can switch to the first communication mode according to the first relevant information, realizing the cross-region switching of the communication mode of the access device, ensuring the service continuity of the terminal in the connected state, solving the problems in the engineering applications of communication systems such as non-terrestrial network communication systems, and meeting the communication requirements of communication systems such as non-terrestrial network communication systems in complex earth coverage scenarios.

[0196] Based on the above communication mode switching method, the embodiment of the present application further provides a switching method for the communication mode of an access device, which is applied to the access device, as Figure 7 shown. This method may include the following steps:

[0197] Step S71: When reaching the first time in the preset correspondence, the access device receives the first relevant information sent by the gateway. The preset correspondence is the correspondence between the communication mode and the time for performing the communication mode switching, and the first communication mode is the communication mode corresponding to the first time in the preset correspondence;

[0198] Step S72: The access device switches the communication mode to the first communication mode according to the first relevant information.

[0199] In the technical solution provided by the embodiment of the present application, the time for switching the communication mode and the relevant information of the communication modes in different regions are configured. When the access device moves to a new region and reaches the time for switching the communication mode of this region, such as the first time, the gateway then sends the first relevant information of the first communication mode to the access device. In this way, the access device can switch to the first communication mode according to the first relevant information, realizing the cross-region switching of the communication mode of the access device.
