[0057] In order to make the objects, technical solutions and advantages of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions 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 a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0058] It should be noted that in the embodiments of the present application, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, motion condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0059] In the present application, the terms “comprising”, “containing” or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or system. Without more limitations, the elements defined by the statement “comprising” do not exclude the presence of other identical elements in the process, method, article or system including the elements. In addition, in the present application, if there is a description of “first”, “second”, etc., the description of “first”, “second”, etc. is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by “first”, “second” can explicitly or implicitly include at least one of the features.

[0060] In the present application, the suffix such as “module”, “component” or “unit” used to represent an element is only for the convenience of description of the present application, and has no specific meaning. Therefore, “module”, “component” or “unit” can be used mixedly. For a person of ordinary skill in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the present application.

[0061] Through analysis of the prior art, it is found that in the application scenarios of Internet of Vehicles, such as remote driving scenarios and remote information service scenarios, 5G-V2X terminals also have the needs of continuity, large bandwidth uplink and low latency downlink. Taking remote driving as an example, the uplink network index requirement is uplink latency ≤ 50 ms and uplink rate ≥ 60 Mbps.

[0062] While the current 5G network transmits data using a shared channel, resource allocation is implemented through uplink and downlink scheduling. The uplink RB resource scheduling method measures channel quality through uplink SRS (Sounding Reference Signal) and DMRS (Demodulation Reference Signal), selects appropriate MCS (Modulation and Coding Scheme), allocates corresponding PUSCH (Physical Uplink Shared Channel) resources, and finally passively schedules RB resources according to the channel quality measurement results. For 5G-V2X terminals, this method is only suitable for individual users and cannot be applied to enterprise-level V2X users under a dedicated public network. Moreover, it cannot effectively provide continuous and stable uplink bandwidth support, which makes 5G-V2X terminals unable to adapt to more vehicle networking application scenarios.

[0063] In view of the technical problem that the prior art cannot guarantee the uplink large bandwidth demand of 5G-V2X terminals, the present application provides an uplink RB resource scheduling method, the overall idea of which is as follows:

[0064] Obtain the base station coverage information and base station connection information of the target terminal; wherein the target terminal is a V2X terminal whose historical connection base station sequence matches the preset base station sequence in the trajectory model library and whose historical moving speed reaches a first preset moving speed; perform trajectory prediction according to the base station coverage information, the base station connection information and the trajectory model library to obtain a predicted switching sequence of the base station connected by the target terminal; obtain a predicted connection base station according to the predicted switching sequence; and send an RB resource priority scheduling instruction to the predicted connection base station to schedule or reserve uplink resources in advance.

[0065] Through the above technical solution, the base station coverage information and base station connection information of the target terminal are obtained, the trajectory prediction is performed in combination with the preset trajectory model library, the predicted switching sequence of the base station connected by the target terminal is obtained, and the predicted connection base station, i.e. the next base station to be connected by the target terminal, is obtained. Then, the RB resource priority scheduling instruction is sent to the predicted connection base station, which realizes the purpose of scheduling or reserving uplink resources in advance before the target terminal connects the base station, guarantees the uplink large bandwidth demand of 5G-V2X terminals, and improves the flexibility and scheduling efficiency of RB resource scheduling.

[0066] Embodiment one

[0067] Reference Figure 1The flowchart illustrates an embodiment of the uplink RB resource scheduling method of the present invention, which is applied to a terminal device.

[0068] The terminal device refers to a V2X terminal capable of achieving 5G network connectivity.

[0069] like Figure 2 The diagram shown is a schematic of the hardware structure of a terminal device. The terminal device may include: a processor 1001, such as a CPU (Central Processing Unit), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

[0070] Those skilled in the art will understand that Figure 2 The hardware structure shown does not constitute a limitation on the terminal device of the present invention. It may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0071] Specifically, the communication bus 1002 is used to realize the connection and communication between these components;

[0072] User interface 1003 is used to connect to the client and communicate data with the client. User interface 1003 may include output units, such as a display screen, and input units, such as a keyboard. Optionally, user interface 1003 may also include other input / output interfaces, such as standard wired interfaces and wireless interfaces.

[0073] The network interface 1004 is used to connect to the backend server and communicate data with the backend server. The network interface 1004 may include input / output interfaces, such as standard wired interfaces and wireless interfaces, such as Wi-Fi interfaces.

[0074] The memory 1005 is used to store various types of data, such as instructions for any application or method in the terminal device, as well as application-related data. The memory 1005 can be a high-speed RAM memory or a stable memory, such as a disk storage. Optionally, the memory 1005 can also be a storage device independent of the processor 1001.

[0075] For details, please refer to... Figure 2 The memory 1005 may include an operating system, a network communication module, a user interface module, and a computer program. The network communication module is mainly used to connect to the base station and conduct wireless data communication with the base station.

[0076] The processor 1001 is used to call the computer program stored in the memory 1005 and perform the following operations:

[0077] obtain base station connection information of the target terminal; wherein the target terminal is a V2X terminal whose historical connection base station sequence matches a preset base station sequence in a trajectory model library and whose historical moving speed reaches a first preset moving speed;

[0078] perform trajectory prediction according to the base station coverage information, the base station connection information, and the trajectory model library, to obtain a predicted switching sequence of base stations to which the target terminal connects;

[0079] obtain a predicted connection base station according to the predicted switching sequence;

[0080] send an RB resource priority scheduling instruction to the predicted connection base station, to schedule or reserve uplink resources in advance.

[0081] Based on the terminal device described above, the uplink RB resource scheduling method of the present embodiment will be described in detail below in combination with the flowchart shown in Figure 1 The method can include the following steps:

[0082] Step S100: obtain base station coverage information and base station connection information of a target terminal; wherein the target terminal is a V2X terminal whose historical connection base station sequence matches a preset base station sequence in a trajectory model library and whose historical moving speed reaches a first preset moving speed.

[0083] Specifically, before obtaining the base station coverage information and the base station connection information of the target terminal, it is necessary to determine whether the current V2X terminal is a target terminal meeting the conditions. The present embodiment will be described by taking the V2X terminal in the schematic diagram shown in Figure 3

[0084] Specifically, the method for determining the target terminal is as follows:

[0085] Step A: obtain historical connection base station information of the V2X terminal, the historical connection base station information including basic information of the historical connection base station and a time when the connection with the historical connection base station is established.

[0086] Specifically, for any V2X terminal, it is necessary to determine whether the V2X terminal is a terminal driving on a road, i.e., a target terminal. First, the basic information of the base station to which the terminal is historically connected needs to be obtained, specifically the base station number and position corresponding to the historical connection base station, and the time when the terminal respectively establishes a connection with these base stations.

[0087] In the present embodiment, as shown in Figure 3 ​The V2X terminal shown, when driving from left to right on Road A, obtains the numbers A1 and A2 of the base stations it has historically connected to, the position information (x1, y1) of A1 and the position information (x2, y2) of A2, and the time t1 of establishing a connection with base station A1 and the time t2 of establishing a connection with base station A2.

[0088] Step B: According to the historical connection base station information, the historical connection base station sequence and the historical moving speed of the V2X terminal are obtained.

[0089] Specifically, the historical moving speed is obtained according to the distance between any two base stations in the historical connection base stations, the difference between the time of connecting the first base station and the time of connecting the second base station in the two base stations. In order to further accurately calculate the historical moving speed, the average of the moving speeds between multiple groups of base stations can also be taken as the historical moving speed.

[0090] In this embodiment, the numbers of the V2X terminal's historically connected base stations are A1 and A2, so the historical connection base station sequence of the terminal is A1A2, and the historical moving speed is:

[0091]

[0092] Step C: According to the preset trajectory model library, it is judged whether the historical connection base station sequence matches the preset base station sequence and whether the historical moving speed reaches the first preset moving speed.

[0093] Specifically, before step C, there is also a step of establishing a trajectory model library, including:

[0094] The numbers of all connected base stations when the road testing terminal drives on the road are obtained, and the preset base station sequence corresponding to the road is obtained.

[0095] According to the preset base station sequence obtained by the road testing terminal on each road, a trajectory model library is constructed.

[0096] In the implementation process, according to the ATU test data of the fourth-class road, the number of connected base stations when the road test terminal drives on the road is obtained, the base station sequence corresponding to the road is obtained, and thus the preset base station sequence is obtained. For example, the road test terminal drives on road A, and the corresponding base station numbers are A1, A2, A3, A4, and A5. However, the road is bidirectional, so there are two preset base station sequences corresponding to the road: the first sequence of road A is A1A2A3A4A5A6, and the second sequence of road A is A6A5A4A3A2A1. According to the above method, all roads are tested, and the preset base station sequences corresponding to the multiple roads are obtained. Finally, according to the preset base station sequences, a database is constructed, and a trajectory model library is obtained. For example, the trajectory model library constructed in this embodiment includes:

[0097] The first sequence of road A is A1A2A3A4A5A6.

[0098] The second sequence of road A is A6A5A4A3A2A1.

[0099] The first sequence of road B is B1B2B3B4B5B6.

[0100] The second sequence of road B is B6B5B4B3B2B1.

[0101] For the above trajectory model library, it is determined whether the historical connection base station sequence A1A2 of this embodiment matches the preset base station sequence in the trajectory model library, and whether the historical moving speed v1 reaches the first preset moving speed V1.

[0102] Requiring the historical moving speed to reach the first preset moving speed can exclude the case that the terminal stops and the user actively switches the base station, which is misjudged as the terminal driving on the road, and can exclude abnormal situations such as base station switching caused by slow walking of pedestrians instead of terminal driving.

[0103] Step D: If the historical connection base station sequence matches the preset base station sequence, and the historical moving speed reaches the first preset moving speed, the V2X terminal is determined to be a target terminal.

[0104] In this embodiment, the historical connection base station sequence A1A2 matches the first sequence of road A in the trajectory model library, and the obtained historical moving speed v1 reaches the first preset moving speed V1. At this time, it can be determined that the V2X terminal is the target terminal defined above.

[0105] In this embodiment, the historical connection base station sequence A1A2 matches the first sequence of road A in the trajectory model library, and the obtained historical moving speed v1 reaches the first preset moving speed V1. At this time, it can be determined that the V2X terminal is the target terminal defined above. Figure 3For example, in a case, after determining that the current V2X terminal is a qualified target terminal, the base station coverage information and the base station connection information of the target terminal driving on road A are acquired. The base station coverage information includes a coverage area where the terminal is currently located and a base station corresponding to the coverage area. In the figure, the position of the terminal is located in the coverage area a3, and the base station corresponding to the coverage area a3 is A3. The base station connection information includes a historical connection base station sequence and a current connection base station of the target terminal. In the figure, the terminal is in the coverage area a3, and thus it can be determined that the current connection base station of the target terminal in the figure is A3, and the historical connection base station sequence is A1A2.

[0106] For example, in another case, the black dot in the figure represents a target terminal, road A intersects with road B, and it is assumed that the target terminal drives on road A from left to right and reaches the current position. At this time, the position of the target terminal is located in the coverage area a3 and the coverage area b3 at the same time, and the base stations corresponding to the coverage area a3 and the coverage area b3 are A3 and B3. When the terminal drives on road A, it will first contact the coverage area a3, and in the historical route, there is a section of the route that can only contact the coverage area a3. Therefore, the terminal will be connected with the base station A3, and the method of the embodiment is executed when the terminal is connected with A3 and before connecting the next base station. Therefore, the current connection base station of the target terminal in the figure is A3, and the historical connection base station sequence is A1A2. Figure 4

[0107] Step S200: performing trajectory prediction according to the base station coverage information, the base station connection information and the trajectory model library to obtain a predicted switching sequence of the target terminal connecting base stations.

[0108] Specifically, the base station coverage information includes a coverage base station, and the coverage base station is a base station corresponding to a coverage area where the target terminal is currently located; and the step S200 can include:

[0109] Step S210: determining whether the target terminal is at an intersection according to the number of coverage base stations.

[0110] In the specific implementation process, the actual road has many intersections, and the actual direction of the V2X terminal also corresponds to many kinds. Based on this situation, to predict the switching sequence of the target terminal connecting base stations, the current state of the target terminal needs to be acquired, including whether it is at an intersection. For example, Figure 3 Fig. 2 shows a base station coverage area diagram when the target terminal is not at an intersection; and Figure 4 Fig. 3 shows a base station coverage area diagram when the target terminal is at an intersection.

[0111] ​Step S220: When there is only one covering base station, it is determined that the target terminal is not at an intersection, trajectory prediction is performed according to the base station connection information and the trajectory model library, and a first predicted handover sequence of the target terminal connecting base stations is obtained.

[0112] This step corresponds to the case shown in FIG. 1, where the target terminal has only one covering base station A3, and it can be determined that the target terminal is not at an intersection. Therefore, a preset base station sequence in the trajectory model library can be directly called to perform trajectory prediction in combination with the current connection base station of the target terminal, and a first predicted handover sequence is obtained. Figure 3

[0113] More specifically, the base station connection information includes a historical connection base station sequence and a current connection base station of the target terminal; and the step S220 can include:

[0114] Step S221: According to the current connection base station, searching in the trajectory model library to obtain a corresponding first initial trajectory.

[0115] In this embodiment, the current connection base station of the target terminal is A3, and searching in the trajectory model library is performed. Specifically, according to the first sequence of road A and the second sequence of road A in the trajectory model library, the corresponding first initial trajectory A4A5A6, A2A1 is obtained. There are two predicted handover sequences, so it is not possible to better predict whether the next connection base station is A4 or A2. Therefore, further confirmation is needed.

[0116] Step S222: According to the historical connection base station sequence, determining the trajectory direction of the target terminal.

[0117] In this embodiment, Figure 3 the historical connection base station sequence of the target terminal is A1A2. According to the sequence, in combination with the trajectory model library, it can be known that the trajectory direction should be from A1 to A6, i.e., the direction corresponding to the first sequence of road A.

[0118] Step S223: According to the first initial trajectory and the trajectory direction, a first predicted handover sequence is obtained.

[0119] In this embodiment, according to the trajectory direction determined in step S222 and the first initial trajectory obtained in step S221, it can be predicted that the handover sequence of the target terminal is A4A5A6, i.e., a first predicted handover sequence is obtained.

[0120] Step S230: When there are two or more covering base stations, it is determined that the target terminal is at an intersection, trajectory prediction and trajectory correction are performed according to the base station coverage information, the base station connection information and the trajectory model library, and a second predicted handover sequence of the target terminal connecting base stations is obtained. ​

[0121] This step corresponds to the case shown in the figure, where the target terminal has two coverage base stations, i.e., A3 and B3, and it can be determined that the target terminal is at an intersection, so when trajectory prediction is performed, multiple cases need to be considered, multiple trajectories are predicted, including trajectories in different directions, and then trajectory correction is performed to obtain a second predicted handover sequence. Figure 4

[0122] More specifically, the base station coverage information further includes a first time and a second time, the first time being a time when the target terminal enters the coverage area, and the second time being a time when the target terminal leaves the coverage area; the step 230 can include:

[0123] Step S231: According to the coverage base station and the currently connected base station, searching in the trajectory model library to obtain a plurality of corresponding second initial trajectories and their starting base stations.

[0124] In this embodiment, the coverage base stations of the target terminal are A3 and B3, and the currently connected base station is A3, so A3 does not need to be considered when obtaining the initial trajectory. Searching in the trajectory model library, according to the first sequence of road A and the second sequence of road A, and the first sequence of road B and the second sequence of road B in the trajectory model library, a plurality of corresponding second initial trajectories are obtained, including A4A5A6, A2A1, B3B4B5, B3B2B1, and the starting base stations corresponding to the second initial trajectories are A4, A2, and B3.

[0125] Step S232: According to the distance between each of the starting base stations and the currently connected base station, a plurality of relative moving speeds of the target terminal per unit time are obtained, to determine a second preset moving speed according to the plurality of relative moving speeds.

[0126] Specifically, according to the relative moving speed, it is determined whether the actual moving trajectory of the target terminal is straight or turning. Because in the actual base station arrangement, the base station positions are in a grid form, that is, the base stations B3, A4, and A3 form a right triangle structure. Therefore, the distance between the base station B3 and the base station A3 will be greater than the distance between the base station A4 and the base station A3, and correspondingly, the speed based on these two distances, i.e., the relative moving speed of turning from A3 to B3, will also be greater than the relative moving speed of directly moving from A3 to A4.

[0127] In this embodiment, it is assumed that the position information of A4 is (x4, y4), the position information of A2 is (x2, y2), the position information of B3 is (m3, n3), and the position information of the currently connected base station A3 is (x3, y4). According to the above second initial trajectories, the reference values of the relative moving speeds of the target terminal per unit time T corresponding to different second initial trajectories are respectively:

[0128] ​The relative moving speed of the currently connected base station A3 to the starting base station A4 is:

[0129]

[0130] The relative moving speed of the currently connected base station A3 to the starting base station A2 is:

[0131]

[0132] The relative moving speed of the currently connected base station A3 to the starting base station B3 is:

[0133]

[0134] wherein, , .

[0135] According to the above relationship, a second preset moving speed can be set according to actual conditions, for example, the second preset moving speed V2 is set as

[0136] In this embodiment, the target terminal is continuously driving, and based on the position of the previous unit time and the current position, the real-time relative moving speed v2 of the target terminal can be calculated. At this time, the actual driving direction of the target terminal cannot be determined.

[0137] Step S233: judging whether the real-time relative moving speed of the target terminal reaches the second preset moving speed.

[0138] Specifically, the real-time relative moving speed v2 obtained in step S232 is compared with the second preset moving speed V2 to determine the moving track direction of the target terminal.

[0139] Step S234: if the real-time relative moving speed does not reach the second preset moving speed, it is determined that the moving track of the target terminal is straight, and the straight direction of the target terminal is determined according to the historical connection base station sequence of the target terminal.

[0140] In this embodiment, if the real-time relative moving speed v2 is less than the second preset moving speed V2, it indicates that the target terminal is moving to A4 or A2, and the moving track is a straight track. At this time, B3B4B5 and B3B2B1 in the second initial track can be removed to correct the predicted track, that is, the second initial track further includes A4A5A6 and A2A1.

[0141] Continuously, according to the historical connection base station sequence A1A2 of the target terminal, it can be known that the actual straight direction is from A1 to A6, that is, the direction corresponding to the first sequence of road A. ​

[0142] Step S235: obtaining a second predicted handover sequence according to the second initial trajectory and the straight direction.

[0143] In this embodiment, according to the straight direction determined in step S234 and the second initial trajectory, the final screening is performed. Specifically, according to the four second initial trajectories in this embodiment, the B3B4B5 and B3B2B1 corresponding to the turning trajectory are removed, and from A4A5A6 and A2A1, in combination with the straight direction determined in step S234, the handover sequence of the target terminal can be predicted as A4A5A6, that is, the second predicted handover sequence is obtained.

[0144] Step S236: if the real-time relative moving speed reaches a second preset moving speed, it is determined that the moving trajectory of the target terminal is turning, and the turning direction of the target terminal is determined according to the time difference between the first time and the second time.

[0145] Specifically, the step of determining the turning direction of the target terminal according to the time difference between the first time and the second time includes: when the time difference is greater than a preset time difference, it is determined that the turning direction of the target terminal is toward the direction of the coverage base station; and when the time difference is less than the preset time difference, it is determined that the turning direction of the target terminal is away from the direction of the coverage base station.

[0146] In this embodiment, if the real-time relative moving speed v2 is greater than or equal to the second preset moving speed V2, it indicates that the target terminal is moving toward B3, and the moving trajectory is a turning trajectory. At this time, A4A5A6 and A2A1 in the second initial trajectory can be removed to correct the predicted trajectory, that is, the second initial trajectory further includes B3B4B5 and B3B2B1. At this time, B3 is a coverage base station, not a terminal connection base station, and the coverage area is b3.

[0147] Continuing, a time difference is calculated according to the time when the target terminal enters the coverage area b3, that is, the first time, and the time when the target terminal leaves the coverage area b3, that is, the second time. Because the base station B3 is definitely on one side of the current road A, and the terminal is in a turning state, it is necessary to determine whether it is left turning or right turning. For example, Figure 4 If the terminal moves toward the base station B3, it can be determined that the turning direction of the target terminal is toward the direction of the coverage base station, that is, the left turning direction in the figure. If the terminal moves toward the base station B4, that is, away from the base station B3, it can be determined that the turning direction of the target terminal is away from the direction of the coverage base station, that is, the right turning direction in the figure. According to the above method, the actual turning direction of the target terminal is determined.

[0148] Step S237: obtaining a second predicted handover sequence according to the second initial trajectory and the turning direction.

[0149] In this embodiment, according to the turning direction determined in step S236 and the second initial trajectory, the final screening is performed. Specifically, according to the four second initial trajectories in this embodiment, the straight trajectory corresponding A4A5A6 and A2A1 are proposed from B3B4B5 and B3B2B1, in combination with the turning direction determined in step S236, such as the right turning direction, it can be predicted that the switching sequence of the target terminal is B3B4B5, that is, the second predicted switching sequence is obtained.

[0150] In the specific implementation process, the obtained second predicted switching sequence can be further corrected to obtain the final second predicted switching sequence. For example, since the target terminal only passes through the coverage area b3 of the base station B3 during the right turning process, it will not establish a connection with the base station B3, and the time spent in the coverage area b3 is short, and it will soon enter the coverage area b4 of the base station B4, therefore, the starting base station with a short contact time in the second predicted switching sequence, that is, the base station B3 here, can be deleted, so as to obtain the final second predicted switching sequence as B4B5.

[0151] The above steps obtain the actual moving direction of the target terminal in combination with the real-time moving speed and moving direction of the target terminal, eliminate and screen the initial trajectory obtained by prediction, so as to obtain the optimal and most possible predicted switching sequence.

[0152] Step S300: obtaining a predicted connection base station according to the predicted switching sequence.

[0153] In this embodiment, for the case of Figure 3 , the first predicted switching sequence is A4A5A6, and the predicted connection base stations obtained in turn are the base station A4, the base station A5, and the base station A6, that is, the Figure 3 next base station to be connected by the mobile terminal is A4; for the case of Figure 4 , the second predicted switching sequence is B4B5, and the predicted connection base stations obtained in turn are the base station B4 and the base station B5, that is, the Figure 4 next base station to be connected by the mobile terminal is B4.

[0154] Step S400: sending an RB resource priority scheduling instruction to the predicted connection base station to schedule or reserve uplink resources in advance.

[0155] Specifically, when the next connection base station is obtained according to the predicted switching sequence in step S300, the corresponding RB resource priority scheduling instruction is sent to the base station, wherein the RB resource priority scheduling instruction includes a service priority level, for example, the priority of the enterprise user is higher than that of the individual user, and the base station can process the obtained RB resource priority scheduling instruction according to the priority level to realize early scheduling or reservation of uplink resources, and effectively guarantee the uplink large bandwidth of the target terminal.

[0156] The uplink RB resource scheduling method provided by the embodiment, by obtaining the base station coverage information and the base station connection information of the target terminal, combining the preset trajectory model library, performing trajectory prediction, obtaining the predicted switching sequence of the target terminal connection base station, and obtaining the predicted connection base station, i.e. the next base station to be connected by the target terminal, and then sending the RB resource priority scheduling instruction to the predicted connection base station, the purpose of early scheduling or reserving uplink resources before the target terminal connects the base station is realized, the demand for uplink large bandwidth of the 5G-V2X terminal is guaranteed, and the flexibility and scheduling efficiency of the RB resource scheduling are improved.
