[0002] With the rapid development of high-speed rail technology and the rapid deployment and opening of high-speed rail lines, more and more users are choosing to travel by high-speed rail. In order to meet the communication needs of mobile users traveling by high-speed rail and to ensure the quality of communication for them, operators have chosen to deploy high-speed rail dedicated networks to serve mobile users traveling by high-speed rail.

[0003] The dedicated network for high-speed rail is very different from ordinary public LTE networks. In the dedicated network for high-speed rail, multiple RRUs (Remote Radio Units) are cascaded together to form a cell to serve mobile users on the high-speed rail.

[0004] When users move within the high-speed rail dedicated network, they may pass through tunnels. Since the base stations in the high-speed rail dedicated network are generally located outside the tunnels, the signal coverage inside the tunnels is relatively weak, which affects the communication quality of users entering the tunnels. Summary of the Invention

[0005] In view of the above, embodiments of this disclosure provide a data request method, a request receiving method, a data request apparatus, a request receiving apparatus, a communication apparatus, and a computer-readable storage medium to solve the technical problems in the related art.

[0024] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0026] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, a first position may also be referred to as a second position without departing from the scope of embodiments of this disclosure, and similarly, a second position may also be referred to as a first position. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0028] Figure 1 This is a schematic flowchart illustrating a data request method according to an embodiment of the present disclosure. The data request method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0029] like Figure 1 As shown, the data request method may include the following steps:

[0030] In step S101, a request message is sent to the network device before the terminal enters the area where communication is affected;

[0031] The request information is used to request the network device to send the data that the terminal will use in the area to the terminal.

[0032] In one embodiment, the terminal may pass through areas where communication is affected during its movement. For example, when the terminal moves on a highway, such as when a user holding a mobile phone is driving a car on a highway, i.e., the mobile phone is moving in a public area, it may pass through areas where communication is affected, including tunnels through which the highway passes; similarly, when the terminal moves within a dedicated high-speed rail network, it may pass through areas where communication is affected, including tunnels through which the high-speed rail passes. The following embodiments mainly illustrate the technical solutions of this disclosure in the scenario of the terminal moving within a dedicated high-speed rail network.

[0033] In one embodiment, the network equipment includes network equipment in a dedicated high-speed rail network; and / or the area includes tunnels.

[0034] The terminal can determine the first time it enters the area and then send a request message to the network device before the first time; the terminal can also determine the first location it enters the area and then send a request message to the network device before the first location.

[0035] Since communication by the terminal in the area will be affected, for example, if the area includes a tunnel, the communication quality of the terminal will be reduced or even interrupted when a user on a high-speed train enters the tunnel with the terminal, which will affect the services performed by the terminal.

[0036] For example, before entering the tunnel, a user is watching an online video on their device. After entering the tunnel, due to the reduced communication quality, the data transmission rate of the video service will decrease or even be interrupted, causing the video playback to stutter or even stop, which seriously affects the user experience.

[0037] According to embodiments of this disclosure, before entering an area where communication is affected, a terminal can send a request message to a network device. This request message can be carried in RRC (Radio Resource Control) signaling and sent to the network device to request the network device to send the data that the terminal will use in the area in advance. As a result, the terminal can receive the data that it will use after entering the area before entering it, and then use the pre-received data after entering the area. This ensures the continuity of the terminal's services before and after entering the area, thereby guaranteeing a good user experience.

[0038] In one embodiment, the request information also carries at least one of the following auxiliary information:

[0039] The amount of data mentioned;

[0040] The time when the data was sent;

[0041] The duration for which the data is transmitted.

[0042] The terminal may also include auxiliary information in the request information sent to the network device for the network device's reference. It should be noted that this auxiliary information is for the network device's reference only and does not determine the network device's actions. That is, the network device may choose to send the data requested by the terminal based on the auxiliary information, or it may choose not to send the data requested by the terminal based on the auxiliary information, but instead send data to the terminal according to its own configuration or protocol agreements.

[0043] For example, the request information may also carry the amount of data that the terminal requests the network device to send in advance. Based on this, the network device can send the data amount to the terminal. Of course, the network device can also determine the amount of data to send as needed.

[0044] For example, the request information may also include the terminal's request for the network device to send data in advance, so that the network device can send the data to the terminal at the specified time. Of course, the network device may also determine the time to send the data as needed.

[0045] For example, the request information may also include the duration for which the terminal requests the network device to send data in advance. Based on this, the network device can send the specified amount of data to the terminal. Of course, the network device can also determine the amount of data to send as needed.

[0046] In one embodiment, the method further includes: determining the data volume based on at least one of the following information:

[0047] The duration of the terminal's journey through the area, for example, the duration of the journey is positively correlated with the amount of data;

[0048] The terminal's moving speed, for example, is positively correlated with the amount of data;

[0049] The business type of the data;

[0050] The quality of service of the data, for example, is positively correlated with the amount of data.

[0051] In one embodiment, the terminal can determine the transit time through the area, and then determine the amount of data to be requested based on the transit time. Since a longer transit time means more data the terminal needs in the area, and thus a larger amount of data to be requested, the transit time can be set to be positively correlated with the amount of data to ensure that the amount of requested data meets the terminal's usage needs in the area.

[0052] In one embodiment, the terminal can determine its own movement speed, such as its current movement speed or its movement speed in the area, and then determine the amount of data to be requested based on that movement speed. Since the faster the terminal moves, the lower the communication quality, to overcome this, the network device can enhance the terminal's coverage, for example, by repeatedly sending the data to the terminal. That is, the data amount in this embodiment can refer to the total amount of data transmitted multiple times; in other embodiments, the data amount can be the amount of data transmitted in a single transmission. Therefore, speed can be set to be positively correlated with data amount, and further, speed can be set to be positively correlated with the number of retransmission requests. That is, the higher the speed, the more times the network device can be requested to retransmit the data to the terminal, thereby improving the terminal's decoding success rate of the requested data and ensuring that the terminal can successfully decode the data sent by the network device during high-speed movement.

[0053] In one embodiment, the terminal can determine the service type of the data to be used in the area, and then determine the amount of data to be requested based on the service type. For example, when the service type is a video service (e.g., online video), the amount of data to be requested is relatively large; when the service type is an audio service (e.g., online music), the amount of data to be requested is relatively small. Of course, the service type is not limited to the two mentioned above, and can also include other service types, such as FTP (File Transfer Protocol) service, WWW service (a type of mobile communication service), etc.

[0054] In one embodiment, the terminal can determine the quality of service (QoS) of the data to be used in the region, and then determine the amount of data to be requested based on the QoS. Since for most services, higher QoS corresponds to a larger amount of data, the QoS can be set to be positively correlated with the data amount to ensure that the requested data amount meets the QoS requirements of the terminal in the region.

[0055] The following examples illustrate how to determine the time to send the data.

[0056] In one embodiment, the method further includes: determining the time based on at least one of the following information:

[0057] The duration of the journey through the region, for example, the longer the journey, the earlier the time;

[0058] The terminal's moving speed, for example, the greater the moving speed, the earlier the time.

[0059] In one embodiment, the time when the data is sent in the auxiliary information can be determined by the terminal. For example, the terminal can determine the path length through the area and then determine the data transmission time based on the path length. Since a longer path length requires a larger amount of data in the area, the transmission time can be set to be earlier for a longer path length. For example, when the path length is less than or equal to a duration threshold, the data transmission time is a first time; when the path length is greater than the duration threshold, the data transmission time is a second time, which is earlier than the first time. This ensures that when the terminal needs to use a larger amount of data, the network device can send the data to the terminal earlier, ensuring that the data delivery is completed when the terminal enters the area, thus meeting the terminal's usage needs.

[0060] In one embodiment, the time at which the data is sent in the auxiliary information can be determined by the terminal. For example, the terminal can determine its own movement speed and then determine the time to send the data based on that speed. As described in the previous embodiments, the higher the movement speed, the larger the amount of data requested. Therefore, the higher the movement speed, the earlier the time can be set. For example, when the movement speed is less than or equal to a speed threshold, the data is sent at a first time; when the movement speed is greater than the speed threshold, the data is sent at a second time, which is earlier than the first time. This allows the network device to send the data to the terminal earlier when a larger amount of data is needed, ensuring that the data is delivered before the terminal enters the area, thus meeting the terminal's usage needs.

[0061] Figure 2 This is a schematic flowchart illustrating another data request method according to embodiments of the present disclosure. Figure 2 As shown, sending a request message to the network device before the terminal enters the area where communication is affected includes:

[0062] In step S201, the first time and / or first location upon entering the area are determined;

[0063] In step S202, a request message is sent to the network device at a second time and / or a second location;

[0064] Wherein, the second time is before the first time and is separated from the first time by a preset time interval, and the second position is before the first position and is separated from the first position by a preset distance.

[0065] In one embodiment, the terminal can determine a first time when it enters the area, and then determine a second time before the first time. For example, it can determine the second time as the time before the first time that is a preset time apart from the first time, and send a request message to the network device at the second time.

[0066] In one embodiment, the terminal can determine a first position upon entering the area, and then determine a second position preceding the first position. For example, the second position can be determined as a position preceding the first position at a preset distance from the first position, and a request message can be sent to the network device from the second position. It should be noted that when the terminal is in the high-speed rail dedicated network, both the first and second positions can be located in the high-speed rail dedicated network, such as on the high-speed rail track. The second position preceding the first position means that the second position is closer to the terminal than the first position, that is, the terminal will pass through the second position first and then the first position.

[0067] Figure 3 This is a schematic flowchart illustrating yet another data request method according to embodiments of the present disclosure. Figure 3 As shown, determining the first time and / or first location upon entering the area includes:

[0068] In step S301, the first time is predicted based on big data of historical movement information of terminals entering the area and a model learned from artificial intelligence.

[0069] In one embodiment, big data of historical movement information of terminals entering the area can be learned based on artificial intelligence (e.g., machine learning, deep learning) to obtain a model with input including the terminal's movement information and output including the first time. Based on this model, the terminal can predict the first time of arrival at the first location.

[0070] The terminal's movement information includes, but is not limited to, the terminal's movement speed before entering the area, environmental factors (such as wind speed and weather), and the time of entry into the area. The historical movement information of each terminal when entering the area can be recorded, and a training sample set can be constructed based on the recorded information. Then, artificial intelligence is used to learn from the training sample set to obtain a model that can predict the first time of entry into the area.

[0071] The process of obtaining the model can be performed by the terminal or by a network device, and the obtained model is then sent to the terminal. The terminal can input its own mobility information into the model, and the time output by the model can be used as the first time the terminal enters the area.

[0072] It should be noted that, in addition to predicting the first time based on the above model, the terminal can also calculate the first time in real time. For example, determining the first time and / or first position upon entering the area includes: predicting the first time based on the terminal's position and speed.

[0073] That is, before entering the area, the terminal can determine its current position and speed, and then determine the distance from the current position to the first position (the length of the high-speed rail track). Then, based on the determined distance and speed, it can determine the time to travel from the current position to the first position. The first time can be obtained by adding the current time to the determined time.

[0074] Figure 4 This is a schematic flowchart illustrating a request receiving method according to an embodiment of the present disclosure. The data request method shown in this embodiment can be executed by a network device that can communicate with a terminal. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The network device includes, but is not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0075] like Figure 4 As shown, the data request method may include the following steps:

[0076] In step S401, a request message is sent by the receiving terminal before entering the area where communication is affected, wherein the request message is used to request the network device to send the data that the terminal will use in the area.

[0077] In one embodiment, the network equipment includes network equipment in a dedicated high-speed rail network; and / or the area includes tunnels.

[0078] The terminal can determine the first time it enters the area and then send a request message to the network device before the first time; the terminal can also determine the first location it enters the area and then send a request message to the network device before the first location.

[0079] Since communication by the terminal in the area will be affected, for example, if the area includes a tunnel, the communication quality of the terminal will be reduced or even interrupted when a user on a high-speed train enters the tunnel with the terminal, which will affect the services performed by the terminal.

[0080] For example, before entering the tunnel, a user is watching an online video on their device. After entering the tunnel, due to the reduced communication quality, the data transmission rate of the video service will decrease or even be interrupted, causing the video playback to stutter or even stop, which seriously affects the user experience.

[0081] According to embodiments of this disclosure, a terminal can send a request message to a network device before entering a communication-affected area. This request message can be carried in RRC signaling and sent to the network device to request the network device to send the data that the terminal will use in the area in advance. As a result, the terminal can receive the data that it will use after entering the area before entering it, and then use the pre-received data after entering the area. This ensures the continuity of the terminal's services before and after entering the area, thereby guaranteeing a good user experience.

[0082] In one embodiment, the request information also carries at least one of the following auxiliary information: the amount of data; the time of sending the data; and the duration of sending the data.

[0083] In one embodiment, the method further includes: sending the data to the terminal based on the auxiliary information.

[0084] The terminal may also include auxiliary information in the request information sent to the network device for the network device's reference. It should be noted that this auxiliary information is for the network device's reference only and does not determine the network device's actions. That is, the network device may choose to send the data requested by the terminal based on the auxiliary information, or it may choose not to send the data requested by the terminal based on the auxiliary information, but instead send data to the terminal according to its own configuration or protocol agreements.

[0085] For example, the request information may also carry the amount of data that the terminal requests the network device to send in advance. Based on this, the network device can send the data amount to the terminal. Of course, the network device can also determine the amount of data to send as needed.

[0086] For example, the request information may also include the terminal's request for the network device to send data in advance, so that the network device can send the data to the terminal at the specified time. Of course, the network device may also determine the time to send the data as needed.

[0087] For example, the request information may also include the duration for which the terminal requests the network device to send data in advance. Based on this, the network device can send the specified amount of data to the terminal. Of course, the network device can also determine the amount of data to send as needed.
