Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to a cell handover method, apparatus, equipment, medium, and product for high-speed rail terminal users. Background Technology

[0002] Currently, in the high-speed rail mobile network scenario, mobile phone users are making increasingly higher demands on the communication and perception services of high-speed rail.

[0003] In related technologies, high-speed rail cells currently experience situations where both high-speed rail (terminal) users and non-high-speed rail (terminal) users are simultaneously present. While the cell can identify low-speed and high-speed users, it cannot distinguish between high-speed rail users and those on highways. This results in non-high-speed rail (terminal) users occupying high-speed rail cell resources, while high-speed rail (terminal) users, like non-high-speed rail (terminal) users, need to constantly measure signals and switch while moving, severely impacting the continuity and smoothness of communication performance, and consequently significantly affecting the user experience.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this disclosure is to provide a cell handover method, apparatus, equipment, medium, and product for high-speed rail terminal users, which can at least to some extent overcome problems such as poor communication continuity for high-speed users due to limitations and defects in related technologies.

[0006] According to a first aspect of the present disclosure, a cell handover method for a high-speed rail terminal user is provided, comprising: predicting handover information of a high-speed rail terminal user between multiple cells based on the high-speed rail's train timetable information and attribute information of multiple cells along the high-speed rail's route; and sending the handover information to the corresponding cells so that the cells can perform cell handover for the high-speed rail terminal user based on the distance between the cells and the high-speed rail.

[0007] In one exemplary embodiment of this disclosure, predicting the handover information of a high-speed rail terminal user between multiple cells based on the high-speed rail timetable information and the attribute information of multiple cells along the high-speed rail route includes:

[0009] The distance between adjacent cells is analyzed from the attribute information of multiple cells along the high-speed rail route.

[0010] Obtain the identifiers of the terminal users reported by two specified adjacent cells;

[0011] By combining the time information, the spacing between adjacent cells, and the terminal user's identifier, the terminal user's identifier is matched with the high-speed rail.

[0012] The matching high-speed rail terminal users are identified, and the handover information of the matching high-speed rail terminal users between multiple cells is predicted in combination with the train timetable information.

[0013] In one exemplary embodiment of this disclosure, obtaining the identifiers of terminal users reported by two designated adjacent cells includes:

[0018] Parse the time information in the train timetable information;

[0019] The movement direction and speed of the high-speed rail mobile user are determined by combining the spacing between adjacent cells, the first cut-out time, and the first cut-in time.

[0020] The terminal user's identifier is matched with the high-speed rail based on the time information, the direction of movement, and the speed of movement.

[0021] In one exemplary embodiment of this disclosure, matching the identifier of the terminal user with the high-speed rail based on the time information, the direction of movement, and the speed of movement includes:

[0022] Based on the relationship between the moving speed and the preset moving speed, the identifiers for high-speed rail terminal users and slow train terminal users are determined in the identifiers of the terminal users.

[0023] The high-speed rail terminal user's identifier is matched with the high-speed rail based on the time information and the direction of movement.

[0024] In one exemplary embodiment of this disclosure, marking the matched high-speed rail terminal user and predicting the handover information of the matched high-speed rail terminal user between multiple cells in conjunction with the train timetable information includes:

[0025] The matched high-speed rail terminal users are identified, and the correspondence between the high-speed rail terminal users and the specified high-speed rail is determined.

[0026] Based on the train timetable information, determine the arrival and departure times of the designated high-speed train through any of the multiple cells.

[0027] Based on the correspondence, the arrival time, and the departure time, predict the entry and exit times of the high-speed rail terminal user in any of the cells;

[0028] The handover information corresponding to the specified high-speed rail is generated based on the identifier of the high-speed rail terminal user, the handover time of any of the cells, and the handover time.

[0029] In one exemplary embodiment of this disclosure, sending the handover information to the corresponding cells so that the cells can perform cell handover for the high-speed rail terminal user based on the distance to the high-speed rail includes:

[0030] The handover information is sent to the corresponding cells so that when the designated high-speed rail enters the cell handover zone based on the distance between the cell and the designated high-speed rail, the cell can instruct the high-speed rail terminal user to perform cell handover in a way that avoids measurement based on the handover information.

[0031] According to a second aspect of the present disclosure, a cell handover device for a high-speed rail terminal user is provided, comprising:

[0032] The prediction module is configured to predict the handover information of high-speed rail terminal users between multiple cells based on the high-speed rail timetable information and the attribute information of multiple cells in the high-speed rail route.

[0033] The sending module is configured to send the handover information to the corresponding cells respectively, so that the cells can perform cell handover for the high-speed rail terminal users based on the distance between them and the high-speed rail.

[0036] According to a fifth aspect of this disclosure, a computer program product is provided, comprising a computer program, characterized in that, when executed by a processor, the computer program implements the cell handover method for high-speed rail terminal users as described in any of the preceding claims.

[0037] In this embodiment, by using the high-speed rail timetable information and the attribute information of multiple cells along the high-speed rail route, the handover information of the high-speed rail terminal user between multiple cells is predicted, and then the handover information is sent to the corresponding cells respectively, so that the cells can perform cell handover for the high-speed rail terminal user according to the distance between them and the high-speed rail. This shortens the handover efficiency and reliability of the high-speed rail terminal user in each cell and improves the continuity and stability of the communication performance of the high-speed rail terminal user.

[0052] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete, and to fully convey the concept of the example embodiments to those skilled in the art.

In the following description, numerous specific details are provided to give a full understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, apparatus, steps, etc., can be employed. In other instances, well-known technical solutions are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0053] Furthermore, the accompanying drawings are merely illustrative of this disclosure, and the same reference numerals in the drawings denote the same or similar parts, thus repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0054] Figure 1 A schematic diagram of an exemplary system architecture for a cell handover scheme for high-speed rail terminal users that can be applied according to embodiments of the present invention is shown.

[0055] like Figure 1 As shown, system architecture 100 may include one or more of terminal devices 101, 102, and 103, a network 104, and a server 105. Network 104 serves as the medium for providing communication links between terminal devices 101, 102, and 103 and server 105. Network 104 may include various connection types, such as wired or wireless communication links or fiber optic cables, etc.

[0056] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, there can be any number of terminal devices, networks, and servers. For example, server 105 could be a server cluster composed of multiple servers.

[0057] Users can use terminal devices 101, 102, and 103 to interact with server 105 via network 104 to receive or send messages, etc. Terminal devices 101, 102, and 103 can be various electronic devices with displays, including but not limited to smartphones, tablets, laptops, and desktop computers, etc.

[0058] In some embodiments, the cell handover method for high-speed rail terminal users provided in this invention is generally executed by server 105, and correspondingly, the cell handover device for high-speed rail terminal users is generally located in terminal device 103 (or terminal device 101 or 102). In other embodiments, some terminals may have functions similar to those of the server device to execute this method.

[0059] The exemplary embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0060] Figure 2 This is a flowchart of a cell handover method for high-speed rail terminal users in an exemplary embodiment of this disclosure.

[0061] refer to Figure 2 Cell handover methods for high-speed rail terminal users may include:

[0062] Step S202: Based on the high-speed rail timetable information and the attribute information of multiple cells along the high-speed rail route, predict the handover information of the high-speed rail terminal user between multiple cells;

[0063] Step S204: The handover information is sent to the corresponding cells so that the cells can perform cell handover for the high-speed rail terminal users based on the distance between them and the high-speed rail.

[0064] In this embodiment, by using the high-speed rail timetable information and the attribute information of multiple cells along the high-speed rail route, the handover information of the high-speed rail terminal user between multiple cells is predicted, and then the handover information is sent to the corresponding cells respectively, so that the cells can perform cell handover for the high-speed rail terminal user according to the distance between them and the high-speed rail. This shortens the handover efficiency and reliability of the high-speed rail terminal user in each cell and improves the continuity and stability of the communication performance of the high-speed rail terminal user.

[0065] The following is a detailed explanation of each step in the cell handover method for high-speed rail terminal users.

[0066] In one exemplary embodiment of this disclosure, such as Figure 3 As shown, based on the high-speed rail timetable information and the attribute information of multiple cells along the high-speed rail route, the predicted handover information of high-speed rail terminal users between multiple cells includes:

[0067] Step S302: Determine the time information of the high-speed train passing through multiple communities based on the high-speed train timetable information;

[0068] Step S304: Analyze the spacing between adjacent cells included in the attribute information of multiple cells in the high-speed rail route;

[0069] Step S306: Obtain the identifiers of the terminal users reported by the two specified adjacent cells;

[0070] Step S308: Combining the time information, the spacing between adjacent cells, and the terminal user's identifier, match the terminal user's identifier with the high-speed rail;

[0071] Step S310: Mark the matched high-speed rail terminal users, and predict the handover information of the matched high-speed rail terminal users between multiple cells in combination with the train timetable information.

[0072] In the above technical solution, by parsing and determining the distance between adjacent cells and obtaining the identifiers of terminal users reported by two designated adjacent cells, the direction, speed and location of the terminal users can be determined. In addition, based on the train timetable, the direction, speed and location of the high-speed rail can be determined, thereby achieving the matching of high-speed rail terminal users with high-speed rail and determining the handover information of high-speed rail terminal users between multiple cells, so as to reduce the waiting time and delay of cell handover.

[0073] In one exemplary embodiment of this disclosure, such as Figure 4 As shown, obtaining the identifiers of terminal users reported by two specified adjacent cells includes:

[0074] Step S402: Determine the first and second cells in the high-speed rail route based on the train timetable information and the cell distribution range in the attribute information;

[0075] Step S404: Determine the time when the high-speed rail terminal user hands out of the first cell based on the identifier of the terminal user reported by the first cell, and record it as the first handout time;

[0076] Step S406: The identifier of the terminal user reported by the second cell determines the time when the high-speed rail terminal user switches to the second cell, which is recorded as the first switching time.

[0077] In the above embodiments of this disclosure, by determining the first cell and the second cell in the high-speed rail route, and respectively determining the first handover time and the first handover time, high-speed rail terminal users in multiple cells can be screened at the beginning of the high-speed rail journey. This ensures that each cell along the route can know the identifier of the high-speed rail terminal user in advance during the high-speed rail journey, reducing the number of interactions of the high-speed rail terminal user during cell handover, thereby reducing the response time of the high-speed rail terminal user during cell handover.

[0078] In one exemplary embodiment of this disclosure, such as Figure 5 As shown, combining the time information, the spacing between adjacent cells, and the terminal user's identifier, matching the terminal user's identifier with the high-speed rail includes:

[0079] Step S502: Parse the time information in the train timetable information;

[0080] Step S504: Determine the moving direction and moving speed of the high-speed rail mobile user by combining the spacing between the adjacent cells, the first cut-out time, and the first cut-in time;

[0081] Step S506: Match the terminal user's identifier with the high-speed rail based on the time information, the direction of movement, and the speed of movement.

[0082] In the above embodiments of this disclosure, the identifier of the terminal user and the high-speed rail are matched by the time information, the direction of movement and the speed of movement, thereby binding the correspondence between the identifier of the terminal user and the high-speed rail. Based on the train timetable, the arrival time of the high-speed rail terminal user in each cell is estimated, thereby preparing for the handover of the high-speed rail terminal user in advance and improving the reliability and accuracy of cell handover.

[0083] In one exemplary embodiment of this disclosure, such as Figure 6As shown, matching the terminal user's identifier with the high-speed rail based on the time information, the direction of movement, and the speed of movement includes:

[0084] Step S602: Based on the relationship between the moving speed and the preset moving speed, determine the identifier of the high-speed rail terminal user and the identifier used by the slow train terminal in the identifier of the terminal user;

[0085] Step S604: Match the identifier of the high-speed rail terminal user with the high-speed rail based on the time information and the direction of movement.

[0086] In the above embodiments of this disclosure, by determining the identifier of the high-speed rail terminal user and the identifier of the slow train terminal user in the identifier of the terminal user based on the relationship between the moving speed and the preset moving speed, it is possible not only to improve the switching efficiency and reliability of the high-speed rail terminal user, but also to filter out the slow train terminal user to avoid it occupying the cell resources dedicated to the high-speed rail terminal user.

[0087] In one exemplary embodiment of this disclosure, such as Figure 7 As shown, the process of marking the matched high-speed rail terminal users and predicting the handover information of the matched high-speed rail terminal users between multiple cells in conjunction with the train timetable information includes:

[0088] Step S702: Mark the matched high-speed rail terminal users and determine the correspondence between the high-speed rail terminal users and the designated high-speed rail.

[0089] Step S704: Determine the arrival and departure times of the designated high-speed train through any of the multiple cells by combining the train timetable information;

[0090] Step S706: Based on the correspondence, the arrival time, and the departure time, predict the handover time and handover time of the high-speed rail terminal user in any of the cells;

[0091] Step S708: Generate handover information corresponding to the specified high-speed rail based on the identifier of the high-speed rail terminal user, the handover time of any of the cells, and the handover time.

[0092] In one exemplary embodiment of this disclosure, such as Figure 8 As shown, sending the handover information to the corresponding cells so that the cells can perform cell handover for the high-speed rail terminal users based on the distance to the high-speed rail includes:

[0093] Step S802: The handover information is sent to the corresponding cells so that when the designated high-speed rail enters the cell handover zone based on the distance between the cell and the designated high-speed rail, the cell can instruct the high-speed rail terminal user to perform cell handover in a way that avoids measurement based on the handover information.

[0094] In the above embodiments of this disclosure, by sending the handover information to the corresponding cells respectively, the cells can determine when the designated high-speed rail enters the cell handover zone based on the distance between the cells and the designated high-speed rail, and instruct the high-speed rail terminal users to perform cell handover in a way that avoids measurement based on the handover information, thereby further improving the response time and reliability of high-speed rail terminal users when handing over cells.

[0095] In one exemplary embodiment of this disclosure, such as Figure 9 As shown, a high-speed rail (terminal) user intelligent identification and handover control optimization scheme is also proposed. The core module of this scheme is the high-speed rail user intelligent identification and management system 900, which is responsible for estimating the arrival time of each high-speed rail cell along the line based on the departure time information of each station along the high-speed rail train and the location of the high-speed rail cell. Then, combined with the distance between cells and the handover cell pair, it accurately identifies the high-speed rail (terminal) user and the direction of movement from all high-speed mobile users, determines the next handover cell, and notifies the target handover cell of the high-speed rail (terminal) user identifier and the handover cell identifier.

[0096] In one exemplary embodiment of this disclosure, such as Figure 9 As shown, when a high-speed rail (terminal) user passes through high-speed rail cell n-1 and high-speed rail cell n, the base station can identify high-speed and low-speed users through Doppler shift technology. By recording the previous cell (the cell with the high-speed indicator) and calculating the user's dwell time, the high-speed rail (terminal) user and the direction of the train can be determined (the dwell time of two-way trains is determined by cell handover). The specific steps include:

[0097] ① The High-speed Rail User Intelligent Identification and Management System 900 obtains departure and arrival / departure times information for each high-speed rail train from the high-speed rail website / system.

[0098] ②~④ When a high-speed rail (terminal) user passes through high-speed rail cell n-1, high-speed rail cell n-1 detects the high-speed user switching to high-speed rail cell n and reports all high-speed user identifiers and switching information to the high-speed rail user intelligent identification and management system 900. The same action is performed when the high-speed rail (terminal) user passes through high-speed rail cell n.

[0099] ⑤ The High-speed Rail User Intelligent Identification and Management System 900 combines feature matching algorithms such as cell distance, handover cell pair, and train arrival and departure timetable to accurately identify high-speed rail (terminal) users and their movement direction among all high-speed users, and determine the next handover cell as the high-speed rail cell m.

[0100] ⑥ The high-speed rail user intelligent identification and management system 900 will notify the high-speed rail cell m of the high-speed rail (terminal) user identifier and the cell identifier n.

[0101] ⑦ The high-speed rail cell m hosts high-speed rail (terminal) users, and the cell to be cut off is determined as m+1 based on the high-speed rail (terminal) user's entry into the high-speed rail cell n.

[0102] ⑧~⑨ When a high-speed rail (terminal) user enters the handover zone, the high-speed rail cell m notifies the terminal to perform a measurement-free handover to the high-speed rail cell m+1, and at the same time notifies the high-speed rail (terminal) user's identifier to the high-speed rail cell m+1, and the high-speed rail cell m+1 performs the same action.

[0103] In the above embodiments, n is a positive integer greater than or equal to 2, and m is a positive integer greater than n.

[0104] In one exemplary embodiment of this disclosure, combined with Figure 9 and Figure 10 As shown, in the cell handover architecture 1000 for high-speed rail terminal users, the high-speed rail cell supports the use of high-speed rail (terminal) user information provided by the high-speed rail user intelligent identification and management system 900, and determines the cell to be handed over based on the cell to which the high-speed rail (terminal) user is handed over. At the same time, it controls the terminal to perform measurement-free handover, thereby achieving efficient and accurate handover control for high-speed rail (terminal) users and improving the user experience of high-speed rail (terminal) users.

[0105] ① When high-speed rail cell n-1 detects a high-speed user switching to high-speed rail cell n, it reports all high-speed user identifiers and switching information to the high-speed rail user intelligent identification and management system 900.

[0106] ② The High-speed Rail User Intelligent Identification and Management System 900 combines cell distance, handover cell pair, train arrival and departure time schedules to accurately identify high-speed rail (terminal) users and their movement direction among all high-speed users, determines the next handover cell as high-speed rail cell m, and notifies high-speed rail cell m of the high-speed rail (terminal) user identifier and the handover cell identifier n.

[0107] ③ A high-speed rail (terminal) user resides in high-speed rail cell m, and the cell to be cut off is determined as m+1 based on the high-speed rail (terminal) user's entry into high-speed rail cell n.

[0108] ④ The High-speed Rail (Terminal) User Intelligent Identification and Management System 900 sends the High-speed Rail User Identifier + the High-speed Rail Cell n to the High-speed Rail Cell m.

[0109] ⑤ When a high-speed rail (terminal) user enters the handover zone, the high-speed rail cell m notifies the terminal to perform a measurement-free handover to the high-speed rail cell m+1, and at the same time notifies the high-speed rail (terminal) user's identifier to the high-speed rail cell m+1.

[0110] In combination with the above Figures 1 to 10 The embodiments shown, compared with the prior art, have at least the following aspects of inventiveness:

[0111] 1) The High-Speed ​​Rail User Intelligent Identification and Management System 900 estimates the arrival time of high-speed trains to each high-speed rail cell along the line based on the arrival and departure times of high-speed trains at each station. Combining cell distance and handover cell pairs, it accurately identifies the high-speed rail (terminal) user and its direction of movement from all high-speed mobile users, determines the next handover cell, and simultaneously notifies the target handover cell of the high-speed rail (terminal) user's identifier and the handover cell identifier.

[0112] 2) The high-speed rail cell supports the use of high-speed rail (terminal) user information provided by the high-speed rail user intelligent identification and management system 900 to determine the cell to be handed out based on the cell to which the high-speed rail (terminal) user is handed in, and controls the terminal to perform measurement-free handover.

[0113] Corresponding to the above method embodiments, this disclosure also provides a cell handover device for high-speed rail terminal users, which can be used to execute the above method embodiments.
