Description

However, communication through the NTN system can only meet the needs of critical alarms and communication guarantees. The NTN system is difficult to carry large packets of data such as video and frequent communication interactions. At the same time, with the development of network communication technology, the ultra-long coverage network of ground communication network systems such as the fifth generation mobile communication technology (5G) in scenes such as oceans has been gradually built, but due to the limited coverage distance of the network, the NTN system is still needed to meet communication needs.

[0093] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0094] In an embodiment of the present application, a communication switching method, apparatus, device and readable storage medium are proposed to solve the technical problem of poor communication continuity when a terminal performs communication switching connection between a terrestrial communication network system and a non-terrestrial communication network system.

[0095] See also Figure 1 , Figure 1 is a flow chart of a communication switching method applied to a terminal provided in an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0096] Step 101: measure a non-terrestrial communication network and obtain first network information associated with the non-terrestrial communication network.

[0097] In a specific embodiment of the present application, the measurement of the non-terrestrial communication network may be proposed by the terminal itself (eg Figure 2 As shown), the terminal decides to measure the non-terrestrial communication network, or network equipment related to the terrestrial communication network, such as a base station, instructs the terminal to make a measurement (such as Figure 3 As shown). In this way, the terminal can autonomously propose to measure the communication information related to the non-terrestrial communication network, thereby improving the autonomy of the terminal during the communication system switching process, as well as the communication continuity and accuracy during the communication system switching process. In addition, measuring the non-terrestrial communication network in the present application can provide an indicator basis for the subsequent determination of whether the terminal is switched to the non-terrestrial communication network system, thereby improving the accuracy of the communication system switching.

[0098] Among them, the first network information obtained may be communication information between the terminal and the non-terrestrial communication network, such as the terminal's downlink reference signal, synchronization signal / physical broadcast channel signal block (or synchronization signal block) ((Synchronization Signal and PBCH block, SSB), channel state information reference signal (Channel State Information Reference Signal, CSI-RS), etc. The specific indicators used may be reference signal received power (reference signal received power, RSRP), signal-to-noise and interference ratio (signal-to-noise and interference ratio, SINR), channel quality indicator (Channel quality indicator, CQI), rank indicator (Rank indicator, RI), etc., which are used to determine the signal strength of SSB or CSI-RS, etc. In addition, the first network information may also be communication information related only to the non-terrestrial communication network, such as network coverage distance, service data transmission rate that can be carried, etc.

[0099] It is worth mentioning that the non-terrestrial communication network in this application can be a communication network system that can be applied to scenes such as the ocean, sky, and Gobi, for example, a communication system such as the Automatic Identification System (AIS) and the Very High Frequency Data Exchange System (VDES), or a non-terrestrial network (NTN) system such as a satellite and an Unmanned Aircraft System (UAS). This application does not limit the specific application system of the non-terrestrial communication network, which can be determined according to the actual application scenario.

[0100] Step 102: Based on the first network information, determine whether to switch between a terrestrial communication network and a non-terrestrial communication network.

[0101] In an embodiment of the present application, by judging the relevant parameter information in the first network information, for example, the first network information includes the RSRP of SSB, only when the RSRP of SSB does not meet the set range of the preset threshold value, it can be determined that the quality of the communication connection between the terminal and the current terrestrial communication network or the non-terrestrial communication network is poor, and the terminal can switch from the current terrestrial communication network to the non-terrestrial communication network, or from the non-terrestrial communication network to the terrestrial communication network. Alternatively, when the relevant parameter information in the first network information meets the set range of the preset threshold value, it can be determined that the quality of the communication network resident at this time is good and no switching is required. In this way, the continuity, stability and reliability of communication can be improved.

[0102] It is understandable that determining whether to switch from a terrestrial communication network to a non-terrestrial communication network, or switching from a non-terrestrial communication network to a terrestrial communication network, can be determined by the terminal itself (eg Figure 2 It can also be indicated by the terminal based on the ground communication network or the communication network system currently resident (including the ground communication network system and the non-ground communication network system) (such as Figure 3 As shown). Determining whether to switch the communication network system can be determined by the relevant parameter information in the first network information, or by combining the first network information and the communication information related to the current network where the terminal resides, or by combining the non-communication network information obtained by the terminal. By combining and judging multiple parameters, it is possible to more accurately determine whether the terminal needs to switch the communication network system, so as to improve the communication continuity of the terminal during the switching of the communication system.

[0103] Optionally, the measuring the non-terrestrial communication network includes any of the following methods:

[0104] receiving a measurement instruction for measuring the non-terrestrial communication network sent by a network device, and measuring the non-terrestrial communication network based on the measurement instruction; wherein the network device is a network device in a terrestrial communication network;

[0105] measuring the non-terrestrial communication network according to a preset period;

[0106] When a first target parameter does not meet a first target threshold value range, measuring the non-terrestrial communication network, the first target parameter being any one or more of the first target information;

[0107] The first target information includes at least one of the following:

[0108] Network information associated with the terminal and the terrestrial communication network;

[0109] Non-network information obtained by the terminal.

[0110] In a specific embodiment of the present application, the terminal's measurement of a non-terrestrial communication network may be controlled by an indication of a terrestrial communication network in which the terminal is currently located. After the terminal receives indication information from the terrestrial communication network, the terminal may measure the non-terrestrial communication network. For terminals that do not need to switch communication systems, the terrestrial communication network in which they are currently located has met the communication needs, and there is no need to switch to a non-terrestrial communication network, so there is no need to measure the relevant communication information of the non-terrestrial communication network. For terminals that need to switch communication systems, the non-terrestrial communication network may be measured according to the indication of the terrestrial communication network, or it may be measured autonomously according to a preset period, and when the relevant parameter trigger condition exists, when one or more target parameters in the first target parameter are higher or lower than the threshold value, the terminal determines that the non-terrestrial communication network needs to be measured. In this way, the above three optional methods for measuring non-terrestrial communication networks can be selected by the terminal according to actual needs, can meet the needs of various terminals, and improve communication fluency and continuity.

[0111] Furthermore, the first target information includes at least one of the network information associated with the terrestrial communication network and the non-network information acquired by the terminal. Since the first target information is the indicator information for the terminal to determine whether it is necessary to measure the non-terrestrial communication network, the network information associated with the terrestrial communication network can be the quality information of the downlink reference signal measured by the terminal, which can include SSB, CSI-RS, and its related RSRP, SINR, etc., which can be consistent with the first network information. In addition, it can also be the downlink rate of the terminal transmitting data, the estimated uplink rate, and the request (ping) packet success rate, etc.

[0112] The non-network information obtained by the above terminal may be the location information of the terminal, specifically the latitude and longitude information of the terminal, the distance from the covered base station, etc. A latitude and longitude distance table of the base station and the terminal may be drawn in advance to obtain the latitude and longitude information of the terminal or the distance from the covered base station. The non-network information may also be information such as humidity and temperature obtained by the terminal in combination with its own configured sensors, or information obtained based on terminal input, etc., which is not limited in this application.

[0113] Optionally, before the receiving a measurement instruction for measuring the non-terrestrial communication network sent by a network device, the method further includes:

[0114] Reporting a first capability to the network device; the first capability indicates that the terminal supports communication with a non-terrestrial communication network.

[0115] In a specific embodiment of the present application, the terminal needs to measure the signal quality of the non-terrestrial communication network, which requires the terminal to have a communication capability, that is, the terminal needs to have the ability to support the measurement and reporting of the non-terrestrial communication network. Therefore, if the network device in the terrestrial communication network instructs the terminal to measure the non-terrestrial communication network, it needs to determine in advance whether the terminal has the communication capability. Specifically, before the terminal receives the instruction from the network device, it can report to the network device that it has the communication capability, that is, the first capability.

[0116] Optionally, reporting the first capability to the network device includes any of the following methods:

[0117] Reporting the first capability to the terrestrial communication network based on a preconfigured first signaling;

[0118] Reporting the first capability to the terrestrial communication network based on a multiplexed reporting amount, wherein the multiplexed reporting amount is transmitted in a physical uplink control channel or a physical uplink shared channel in the terrestrial communication network;

[0119] Based on a target reporting mechanism preconfigured with the ground communication network, the first capability is reported to the ground communication network.

[0120] Specifically, there are three ways for the terminal to report the first capability to the network device in the terrestrial communication network: first, the terminal can use independent signaling for reporting, such as defining a new IE field Ultra-remote Coverage Flag in the Terminal-New Air Interface-Capability (UE-NR-Capability), and the field can carry 0 or 1 accordingly, where 0 means that the terminal supports measuring non-terrestrial communication networks and can report the first capability to the terrestrial communication network, and 1 means that the terminal does not support measuring non-terrestrial communication networks and does not need to report the first capability to the terrestrial communication network, or the terrestrial communication network can be informed that the terminal does not have the first capability.

[0121] Secondly, the terminal can use the existing reporting mechanism, such as the CSI reporting mechanism in CSI-RS, the SR reporting mechanism, etc. It can also reuse the existing reporting amount for on-line reporting, that is, the reporting amount can be transmitted in PUCCH or PUSCH. Among them, when reusing the existing reporting amount, it is not ruled out that there is a possibility that the reporting amount needs to be calculated with the existing feedback amount to form a new feedback amount value.

[0122] Finally, the terminal can report by adopting a new reporting mechanism, for example, a reporting mechanism similar to the SRS transmission along the reference signal, so that when the terminal sends the reference signal, it can report the network information and non-network information related to the terminal itself to the network device.

[0123] The network information related to the terminal itself may be information such as RSRP / SINR of the downlink reference signal SSB / CSI-RS, or information such as CQI and RI. The non-network information reported by the terminal may specifically be information such as the longitude and latitude position of the terminal. This application does not make any specific restrictions here.

[0124] Optionally, the method further comprises:

[0125] receiving a measurement configuration reference signal sent by a network device;

[0126] Based on the measurement configuration reference signal, perform measurement of the terrestrial communication network to obtain second network information;

[0127] The second network information is sent to the network device.

[0128] It can be understood that the terminal can establish a communication connection with the currently resident terrestrial communication network before measuring the non-terrestrial communication network. The terrestrial communication network can send a measurement configuration reference signal to the terminal to instruct the terminal to measure the downlink reference signal to obtain the second network information, wherein the second network information may also include SSB, CSI-RS, and its related RSRP, SINR, etc., and may also be consistent with the first network information. In addition, the terrestrial communication network can also inform the terminal that a signal needs to be sent for the uplink reference signal.

[0129] Optionally, sending the second network information to the network device includes:

[0130] The second network information and the location information of the terminal are sent to the network device.

[0131] Furthermore, when the terminal sends the second network information to the ground communication network, it can also send the terminal's own location information to the ground communication network. The location information may include the terminal's latitude and longitude information, the distance from the covered base station, etc. In this way, the ground communication network obtains the terminal's location information, and can determine whether to instruct the terminal to switch to the non-ground communication network in combination with the terminal's related communication information and its own communication information, thereby improving the accuracy and effectiveness of the terminal switching communication system.

[0132] Optionally, the determining whether to perform switching between a terrestrial communication network and a non-terrestrial communication network based on the first network information includes:

[0133] Based on the first network information and the pre-acquired first target information, determining whether to switch from the terrestrial communication network to the non-terrestrial communication network, or determining whether to switch from the non-terrestrial communication network to the terrestrial communication network;

[0134] The first target information includes at least one of the following:

[0135] Network information associated with the terminal and the terrestrial communication network;

[0136] Non-network information obtained by the terminal.

[0137] In a specific embodiment of the present application, the terminal can independently determine whether it needs to switch from a terrestrial communication network to a non-terrestrial communication network. Specifically, it can be determined by analyzing the first network information and the pre-acquired first target information, and the combined analysis of multiple parameter information can be performed.

[0138] Among them, the first target information may include the network information associated with the above-mentioned terminal and the ground communication network, which may be the quality information of the downlink reference signal measured by the terminal, which may include SSB, CSI-RS, and its related RSRP, SINR, etc., which may be consistent with the network information in the first target information. In addition, it can also be the downlink rate of the terminal transmitting data, the estimated uplink rate, and the pin packet success rate. At the same time, the non-network information obtained by the above-mentioned terminal may be the location information of the terminal, specifically the latitude and longitude information of the terminal, the distance from the covered base station, etc.

[0139] It is worth mentioning that the above-mentioned combined analysis of multiple parameter information in the first network information and the pre-acquired first target information can specifically unify the dimensions of multiple parameter information to perform linear weighted analysis and determination. Among them, the parameter information obtained in different steps can have different weights. In addition, the historical switching data of the terminal can also be introduced, and the analysis can be combined with multiple parameter information based on a certain weight of the historical switching data, which can more accurately determine whether the terminal needs to switch to a non-terrestrial communication network, thereby improving the accuracy of the switching process and the effectiveness of communication.

[0140] Optionally, the first target information includes at least one of the following:

[0141] Downlink reference signal quality information, downlink channel quality, first downlink rate, terminal location information, and historical switching data.

[0142] In a specific embodiment, the first target information may specifically be the quality information of the downlink reference signal measured by the terminal, the channel quality information on the resource element (RE) of the physical downlink control channel (PDCCH) and the physical downlink shared channel (PDSCH), including but not limited to SSB / CSI-RS RSRP, SSB / CSI-RS SINR, and PDCCH / PDSCH SINR.

[0143] Furthermore, the first target information may also include the downlink rate of the terminal, the location information of the terminal (latitude and longitude information, distance information from the network device, etc.), the perception information obtained by the terminal, etc., and may also include the historical switching data of the terminal. This application does not make any restrictions here, and the specific content of the first target information can be determined according to actual needs.

[0144] Optionally, the determining whether to perform switching between a terrestrial communication network and a non-terrestrial communication network based on the first network information includes:

[0145] Sending the first network information to a network device;

[0146] Upon receiving a switching indication sent by the network device based on the first network information, determining to switch from a terrestrial communication network to a non-terrestrial communication network, or determining whether to switch from a non-terrestrial communication network to a terrestrial communication network;

[0147] Wherein, the network device is a network device in a ground communication network.

[0148] In another embodiment of the present application, the terminal determines whether to switch from the ground communication network to the non-ground communication network by an instruction of the ground communication network. Specifically, after the terminal completes the communication configuration with the currently resident ground communication network, the terminal can send the first network information acquired by the terminal to the network device, and the first network information can be the communication information related to the non-ground communication network at this time, or it can be the information only related to the non-ground communication network.

[0149] In this way, the network device can be based on the first network information and the second target information and the second network information. The second target information at this time may include network information associated with the ground communication network and the terminal, and the second network information may be information that the terminal has acquired and reported to the ground communication network before measuring the non-ground communication network.
