Description

Background Art

[0002] Currently, in the high-speed rail mobile network scenario, mobile phone users have increasingly high requirements for the communication perception service of high-speed rails.

[0003] In the related art, there is currently a situation where high-speed rail (terminal) users and non-high-speed rail (terminal) users co-reside in a high-speed rail cell. The cell can identify low-speed and high-speed users, but it cannot distinguish between high-speed users such as high-speed rail or highway users. As a result, on the one hand, non-high-speed rail (terminal) users occupy the resources of the high-speed rail cell, and on the other hand, high-speed rail (terminal) users need to continuously measure signals and switch during movement like non-high-speed rail (terminal) users, seriously affecting the coherence and fluency of communication performance, and thus seriously affecting the user experience.

In other cases, well-known technical solutions are not shown or described in detail to avoid obscuring the various aspects of the present disclosure.

[0053] In addition, the accompanying drawings are only schematic illustrations of the present disclosure, and the same reference numerals in the drawings denote the same or similar parts, so repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0054] Figure 1 It shows a schematic diagram of an exemplary system architecture of a cell handover solution for high-speed rail terminal users to which the embodiments of the present invention can be applied.

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

[0056] It should be understood that Figure 1 the numbers of terminal devices, networks, and servers in FIG. 1 are merely illustrative. According to the implementation requirements, there can be any number of terminal devices, networks, and servers. For example, the server 105 can be a server cluster composed of multiple servers, etc.

[0057] Users can use the terminal devices 101, 102, 103 to interact with the server 105 through the network 104 to receive or send messages, etc. The terminal devices 101, 102, 103 can be various electronic devices with a display screen, including but not limited to smart phones, tablet computers, portable computers, and desktop computers, etc.

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

[0059] The following will describe the exemplary embodiments of the present disclosure in detail with reference to the accompanying drawings.

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

[0061] Referring to Figure 2 FIG. 2, the cell handover method for high-speed rail terminal users may include:

[0062] Step S202, predicting the handover information of the high-speed rail terminal user between multiple cells according to the train schedule information of the high-speed rail and the attribute information of multiple cells in the high-speed rail travel route;

[0063] Step S204, sending the handover information to the corresponding cells respectively for the cells to perform cell handover on the high-speed rail terminal user according to the distance from the high-speed rail.

[0064] In the embodiments of the present disclosure, by predicting the handover information of a high-speed rail terminal user between multiple cells based on the train timetable information of the high-speed rail and the attribute information of multiple cells in the high-speed rail travel route, and then sending the handover information to the corresponding cells respectively, so that the cells perform cell handover on the high-speed rail terminal user according to the distance from the high-speed rail, the handover efficiency and reliability of the high-speed rail terminal user in each cell are shortened, and the coherence and stability of the communication performance of the high-speed rail terminal user are improved.

[0065] Next, each step of the cell handover method for the high-speed rail terminal user will be described in detail.

[0066] In an exemplary embodiment of the present disclosure, as Figure 3 shown, predicting the handover information of a high-speed rail terminal user between multiple cells based on the train timetable information of the high-speed rail and the attribute information of multiple cells in the high-speed rail travel route includes:

[0067] Step S302, determining the time information of the high-speed rail passing through multiple cells according to the train timetable information of the high-speed rail;

[0068] Step S304, analyzing the distance between adjacent cells included in the attribute information of multiple cells in the high-speed rail travel route;

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

[0070] Step S308, combining the time information, the distance between adjacent cells, and the identifier of the terminal user to match the identifier of the terminal user with the high-speed rail;

[0071] Step S310, 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 combination with the train timetable information.

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

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

[0074] Step S402: Determine the first cell and the second cell in the high-speed rail travel route according to the train schedule information and the cell distribution range in the attribute information;

[0075] Step S404: Determine the time when the high-speed rail terminal user cuts out from the first cell according to the identifier of the terminal user reported by the first cell, denoted as the first cut-out time;

[0076] Step S406: Determine the time when the high-speed rail terminal user cuts into the second cell according to the identifier of the terminal user reported by the second cell, denoted as the first cut-in time.

[0077] In the above embodiments of the present disclosure, by determining the first cell and the second cell in the high-speed rail travel route, and respectively determining the first cut-out time and the first cut-in time, high-speed rail terminal users in multiple cells can be screened out at the initial stage of the high-speed rail journey, thereby ensuring that each cell along the way can know the identifiers of high-speed rail terminal users in advance during the high-speed rail travel, reducing the number of interactions of high-speed rail terminal users during cell handover, and reducing the response time of high-speed rail terminal users when switching cells.

[0078] In an exemplary embodiment of the present disclosure, as Figure 5 shown, combining the time information, the distance between adjacent cells, and the identifier of the terminal user, matching the identifier of the terminal user with the high-speed rail includes:

[0079] Step S502: Analyze the time information in the train schedule information;

[0080] Step S504: Combine the distance between adjacent cells, the first cut-out time, and the first cut-in time to judge the moving direction and moving speed of the high-speed rail mobile user;

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

[0082] In the above embodiments of the present disclosure, the identifier of the terminal user and the high-speed rail are matched through the time information, the moving direction, and the moving speed, thereby binding the corresponding relationship between the identifier of the terminal user and the high-speed rail, estimating the time when the high-speed rail terminal user arrives at each cell based on the train schedule, and preparing in advance for the handover of the high-speed rail terminal user, improving the reliability and accuracy of cell handover.

[0083] In an exemplary embodiment of the present disclosure, as Figure 6As shown, matching the identification of the end user and the high-speed rail based on the time information, the moving direction, and the moving speed includes:

[0084] Step S602: Based on the magnitude relationship between the moving speed and a preset moving speed, determine the identification of the high-speed rail end user and the identification of the slow train end user in the identification of the end user.

[0085] Step S604: Based on the time information and the moving direction, match the identification of the high-speed rail end user and the high-speed rail.

[0086] In the above embodiments of the present disclosure, by determining the identification of the high-speed rail end user and the identification of the slow train end user in the identification of the end user based on the magnitude relationship between the moving speed and a preset moving speed, not only can the handover efficiency and reliability of the high-speed rail end user be improved, but also the slow train end users can be screened out to avoid their occupation of the cell resources dedicated to the high-speed rail end users.

[0087] In an exemplary embodiment of the present disclosure, as Figure 7 shown, marking the matched high-speed rail end user and predicting the handover information of the matched high-speed rail end user between multiple cells in combination with the train schedule information includes:

[0088] Step S702: Mark the matched high-speed rail end user and determine the corresponding relationship between the high-speed rail end user and a specified high-speed rail.

[0089] Step S704: In combination with the train schedule information, determine the arrival time and departure time of the specified high-speed rail passing through any one of the multiple cells.

[0090] Step S706: Based on the corresponding relationship, the arrival time, and the departure time, predict the handover-in time and handover-out time of the high-speed rail end user in any one of the cells.

[0091] Step S708: Generate the handover information corresponding to the specified high-speed rail according to the identification of the high-speed rail end user, the handover-in time, and the handover-out time of any one of the cells.

[0092] In an exemplary embodiment of the present disclosure, as Figure 8 shown, sending the handover information to the corresponding cells respectively for the cells to perform cell handover on the high-speed rail end user according to the distance from the high-speed rail includes:

[0093] Step S802: Send the handover information to the corresponding cell respectively, so that when the cell determines that the specified high-speed rail enters the cell handover zone according to the distance from the specified high-speed rail, the high-speed rail terminal user is instructed to perform cell handover in a non-measurement manner based on the handover information.

[0094] In the above embodiments of the present disclosure, by sending the handover information to the corresponding cell respectively, so that when the cell determines that the specified high-speed rail enters the cell handover zone according to the distance from the specified high-speed rail, the high-speed rail terminal user is instructed to perform cell handover in a non-measurement manner based on the handover information, the response time and reliability of the high-speed rail terminal user for cell handover are further improved.

[0095] In an exemplary embodiment of the present disclosure, as Figure 9 shown, an intelligent identification and handover control optimization scheme for high-speed rail (terminal) users 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 time to reach each high-speed rail cell along the line according to the departure time information of each station along the high-speed rail train and the location of the high-speed rail cell, and then combining the distance between cells and the handover cell pair to accurately identify the high-speed rail (terminal) users and their moving directions from all high-speed moving users, determine the next handover cell, and at the same time notify the target handover cell of the high-speed rail (terminal) user identifier and the handover cell identifier.

[0096] In an exemplary embodiment of the present disclosure, as Figure 9 shown, when the 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- and low-speed users through Doppler shift technology, record the previous handover cell (the handover cell with a high-speed label) and calculate the user residence time to determine the high-speed rail (terminal) user and the oncoming vehicle direction (the residence of a two-way train is judged through the handover cell pair). The specific steps are as follows:

[0097] ① The high-speed rail user intelligent identification and management system 900 obtains the arrival and departure time information of each high-speed rail departure and stop station from the high-speed rail website / system.

[0098] ② - ④ When the high-speed rail (terminal) user passes through high-speed rail cell n-1, high-speed rail cell n-1 detects that a high-speed user switches to high-speed rail cell n, and reports all high-speed user identifiers and handover information to the high-speed rail user intelligent identification and management system 900. The same operation is also 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 schedule to accurately identify the high-speed rail (terminal) users and their moving directions among all high-speed users, and determines that the next handover cell is high-speed rail cell m.

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

[0101] ⑦. The high-speed rail cell m camps the high-speed rail (terminal) user and determines the serving cell as m + 1 according to the high-speed rail (terminal) user's handover to the high-speed rail cell n.

[0102] ⑧ - ⑨. When the 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 cell m + 1 of the high-speed rail (terminal) user identifier. The high-speed rail cell m + 1 performs the same operation.

[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 an exemplary embodiment of the present disclosure, as shown in Figure 9 and Figure 10 , in the cell handover architecture 1000 of the high-speed rail terminal user, the high-speed rail cell supports the high-speed rail (terminal) user information provided by the high-speed rail user intelligent identification and management system 900, determines the serving cell according to the high-speed rail (terminal) user's handover cell, and at the same time controls the terminal to perform a measurement-free handover, so as to realize efficient and accurate handover control of the high-speed rail (terminal) user and improve the usage experience of the high-speed rail (terminal) user.

[0105] ① The high-speed rail cell n - 1 detects that a high-speed user is handing over to the high-speed rail cell n, and reports all high-speed user identifiers and handover 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 accurately identifies the high-speed rail (terminal) user and the moving direction among all high-speed users by combining the cell distance, handover cell pair, train arrival and departure schedules, determines the next handover cell as the high-speed rail cell m, and notifies the high-speed rail cell m of the high-speed rail (terminal) user identifier and the serving cell identifier n.

[0107] ③ The high-speed rail cell m camps the high-speed rail (terminal) user and determines the serving cell as m + 1 according to the high-speed rail (terminal) user's handover to the 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 served high-speed rail cell n to the high-speed rail cell m.

[0109] ⑤ When the 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 cell m + 1 of the high-speed rail (terminal) user identifier.

[0110] Combined with the aboveFigures 1 to 10 In the embodiments shown, compared with the prior art, the creativity of the embodiments of the present disclosure at least includes the following aspects:

[0111] 1) The high-speed rail user intelligent identification and management system 900 estimates the arrival time at each high-speed rail cell along the line according to the arrival and departure time tables of each station of the high-speed rail train, combines the cell distance and handover cell pairs, accurately identifies high-speed rail (terminal) users and their moving directions from all high-speed moving users, determines the next handover cell, and notifies the target handover cell of the high-speed rail (terminal) user identifier and the handover-out cell identifier at the same time.

[0112] 2) The high-speed rail cell supports determining the handover-out cell according to the high-speed rail (terminal) user information provided by the high-speed rail user intelligent identification and management system 900, and controls the terminal to perform measurement-free handover according to the handover-in cell of the high-speed rail (terminal) user.
