[0027] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.
[0028] The network standard selection method provided by the embodiments of the present disclosure is applied to the scenario of selecting the optimal network suitable for a terminal in a high-speed rail scenario. For example, when the 4th generation mobile communication technology (4G) private network interacts with the 5th generation mobile communication technology (5G) public network, and the terminal is in the environment of the high-speed rail operating network of the 4G private network, the 5G public network can be avoided by combining the terminal's status on the high-speed rail and the signal map of the high-speed rail route.
[0029] At present, in the high-speed rail scenario, an operator-specific network is used to improve the terminal communication experience. For the vast majority of high-speed rail lines, a 4G private network is still set up. With the development of technology, some areas have begun to deploy 5G public networks. Therefore, when users are in a high-speed rail environment, they are affected by the limited network layout of the public network. When the 5G public network interacts with the 4G private network, due to the network selection requirements of the 3rd Generation Partnership Project (3GPP) protocol, the 5G public network with high priority is given priority, causing the terminal to reside on the 5G public network that has drifted over, and the signal quality of the 5G public network is very poor. At the same time, when the terminal leaves the area, it will switch to the 4G private network, resulting in slow network speed, and due to the high speed of the high-speed rail, the network is frequently switched, resulting in unstable network signals. In turn, it seriously affects the user experience in the high-speed rail network environment. Figure 1 A schematic diagram showing the signal quality when a high-speed rail 4G private network and a 5G public network intersect. Figure 1 As shown in the figure, A is the 4G private network coverage area, B is the 4G private network coverage area, C is the 5G public network coverage area, H1 is the conventional public network, and H2 is the high-speed rail private network. When the train is running, there is no intersection between the 4G private network and any network in area A. At this time, the terminal signal is good, such as Figure 1 As shown in a1, the video is smooth. Area B is still covered by the 4G private network, but it intersects with the 5G public network in area C. At this time, due to the 3GPP network selection specification, the 5G public network will be selected, resulting in poor terminal signal, as shown in Figure 1 As shown in b1, the video freezes.
[0030] In the disclosed embodiments, the 3GPP network selection specification is: 5G Stand Alone (SA) idle interoperation strategy. The 5G SA idle interoperation strategy implements residency on different layers of networks based on differences in reselection priorities. To achieve 5G, terminals must reside on the 5G network as much as possible. When configuring reselection priorities, the 5G reselection priority must be higher than the 4G reselection priority. Figure 2 A schematic diagram of a 3GPP network selection specification is shown. Figure 2 As shown, 1a is a high-priority cell and 2b is a low-priority cell. When the terminal moves out of the 5G coverage area, it will reselect from the high-priority cell 5G to the low-priority cell 4G. Reselection to the low-priority cell is possible only when the high-priority cell level is below the service threshold and the target cell level is above the low-priority reselection threshold. When the terminal moves into the 5G coverage area, it will reselect from the low-priority cell to the high-priority cell. At this time, the terminal only needs to meet the target cell level above the high-priority cell reselection threshold to reselect to the high-priority cell.
[0031] In view of this, the present disclosure provides a method for selecting a network standard, which is applied to the scenario where the terminal selects the optimal network in the high-speed rail scenario. In this method, the terminal's resident network and the level of the resident network are determined. And based on the determined resident network and the level of the resident network, the network selection strategy is determined. Among them, when the level of the resident network is a low-level private network, the terminal network is forcibly downgraded to a low-level private network. This method can avoid the reselection of high-priority networks due to interference from 5G public network signals, and can achieve the terminal staying in the high-speed rail operation private network throughout the entire process.
[0032] Figure 3 FIG. 1 is a flow chart showing a method for selecting a network standard according to an exemplary embodiment. Figure 3 As shown, the network standard selection method is applied in a terminal and includes the following steps.
[0033] In step S11, in response to determining that the terminal moves on a line with a network standard private network layout, network standard private network layout information corresponding to the line is obtained, and the current network of the terminal is determined.
[0034] In the embodiment of the present disclosure, the network standard private network layout information is used to record the network standard private network corresponding to one or more location points on the line.
[0035] In an example of the present disclosure, the resident network is used to determine the network standard of the network in which the terminal currently resides. For example, the resident network can be a private network environment in which the terminal is located, a public network environment in which the terminal is located, etc.
[0036] In step S12, when the terminal moves to each of the one or more location points, the target network standard is determined based on the network standard of the current resident network and the network standard-specific network layout information.
[0037] In the embodiment of the present disclosure, when a terminal moves to one or more base station locations, the network standard of the network in which the terminal is currently residing is determined. For example, the network standard of the network in which the terminal is currently residing may be: 4G private network, 5G private network, 4G public network, 5G public network, etc.
[0038] In the embodiment of the present disclosure, the target network standard is determined according to the network standard of the network where the terminal currently resides and in combination with the network standard-specific network layout information.
[0039] The disclosed embodiments provide a method for selecting a network standard. This method determines that a terminal is on a mobile route with a dedicated network layout, obtains network standard layout information corresponding to the route, and determines the network the terminal is currently residing on. Based on the network standard of the terminal's current network, combined with the network standard layout information, network standard selection is performed. This method ensures that the user's Internet experience on routes with dedicated network layouts is not affected, and reduces power consumption and poor network stability caused by frequent switching.
[0040] The following describes the method of determining a target network standard based on the network standard of the current resident network and network standard-specific network layout information involved in the embodiment of the present disclosure.
[0041] In an embodiment of the present disclosure, if the current resident network of the terminal at the first location point is a private network of the first network standard, and based on the network standard private network layout information, it is determined that there is a second location point corresponding to a private network of the second network standard, then the terminal determines the target network standard at the second location point based on the first network standard selection strategy.
[0042] For example, in an example of the present disclosure, when the current resident network of the terminal at the first location point is a low-level private network (for example, a 4G high-speed rail private network), and combined with the network standard private network layout information, it is determined that there is a second location point corresponding to a high-level network, then the original Third Generation Partnership Project 3GPP protocol is maintained and a high-level network (for example, a 5G high-speed rail private network) is used.
[0043] In an embodiment of the present disclosure, if the current resident network of the terminal at the first location point is a private network of the first network standard, and it is determined based on the network standard private network layout information that there is no second location point corresponding to the private network of the second network standard, then the terminal determines the target network standard based on the second network standard selection strategy at the second location point.
[0044] For example, in an example of the present disclosure, when the current resident network of the terminal at the first location point is a low-level private network (4G high-speed rail private network), and combined with the network standard private network layout information, it is determined that there is no second location point corresponding to a high-level network, the original Third Generation Partnership Project 3GPP protocol is changed, and the low-level private network (4G high-speed rail private network) is forced to be used at this location point.
[0045] In an example of the present disclosure, the first location point is a location point reached earlier than the second location point when the terminal moves on the line.
[0046] In the embodiment of the present disclosure, the first network standard selection strategy is that when the first network standard private network and the second network standard private network coexist, the priority of selecting the second network standard private network as the current resident network is higher than the priority of selecting the first network standard private network as the current resident network.
[0047] In the embodiment of the present disclosure, the second network standard selection strategy is that when the first network standard private network and the second network standard private network do not coexist, the priority of selecting the first network standard private network as the current resident network is higher than the priority of selecting the second network standard private network as the current resident network.
[0048] In one example of the present disclosure, the first network standard selection strategy may be understood as a network selection strategy that complies with the 3GPP protocol definition, and the second network standard selection strategy may be understood as a network selection strategy that circumvents the 3GPP protocol definition.
[0049] In one example of this disclosure, network standard private network layout information represents the network capabilities of a line signal map. This information, in other words, reflects the distribution of private networks along a given line. For example, the entire Beijing-Zhangjiakou High-Speed Railway line operates on a 5G high-speed rail private network. The entire Beijing-Shanghai High-Speed Railway line operates on a 4G high-speed rail private network, with only certain sections equipped with 5G private networks.
[0050] In the embodiment of the present disclosure, by judging the network standard of the network to which the current terminal resides, and combining the network standard private network layout information to understand in real time the network capabilities of the line with the network standard private network layout, the optimal operating network residence can be accurately selected, and frequent public network signal interference can be reduced. It can improve the user's Internet experience in the high-speed rail network environment and reduce the power consumption loss caused by frequent switching.
[0051] In the embodiment of the present disclosure, a line with a network standard private network layout corresponds to a private network identifier and a corresponding moving speed range. For example, each high-speed rail line corresponds to a high-speed rail private network identifier and carries a moving speed.
[0052] Figure 4 FIG1 shows a flow chart of determining that a terminal moves on a route with a network standard private network layout according to an exemplary embodiment of the present disclosure. Figure 4 As shown, the following steps are included.
[0053] In step S21, it is determined that the current resident network is the network corresponding to the private network identifier.
[0054] In the disclosed embodiment, the current network is determined based on the private network identifier. For example, based on the high-speed rail identifier, it is determined that the network where the terminal currently resides belongs to the high-speed rail range, and thus the terminal is determined to be within the high-speed rail private network range. The high-speed rail identifier is a high-speed train (HST) identifier.
[0055] In the embodiment of the present disclosure, whether there is a high-speed rail identifier is determined by the network where the terminal resides. If the network where the terminal resides is a high-speed rail dedicated network, the terminal is notified by reconfiguring the radio resource control (RRC) to carry the high-speed train (HST) identifier.
[0056] In an example of the present disclosure, if it is determined through the resident network that the terminal contains a resident high-speed rail operation private network identifier, the resident high-speed rail operation private network identifier is used to perceive that the user is in a high-speed rail environment.
[0057] In an example of the present disclosure, if it is determined through the resident network that the terminal does not contain the resident high-speed rail operation private network identifier, the network selection strategy of the 3GPP protocol is restored and the high-speed rail private network is exited.
[0058] In step S22, based on the high-speed rail identification and the real-time speed measurement of the global positioning system, it is confirmed that the terminal is in the high-speed rail state.
[0059] In an embodiment of the present disclosure, if a private network identifier of a corresponding line is received and the moving speed of the terminal is within the moving speed range of the line, it is determined that the terminal is moving on a line with a network standard private network layout.
[0060] In the embodiment of the present disclosure, based on determining that the terminal contains a high-speed rail identifier, the terminal is notified via radio resource control (RRC) reconfiguration carrying the high-speed rail identifier.
[0061] In the disclosed embodiment, after receiving the HST notification, the terminal obtains the real-time position and moving speed of the terminal's Global Positioning System (GPS) to accurately determine the high-speed rail status of the terminal.
[0062] In one example of the present disclosure, determining whether a terminal is on a high-speed train is based on two determinations. The first determination is based on whether the network the terminal is currently on is a high-speed train identifier. Based on the high-speed train identifier, the terminal is confirmed to be on a high-speed train. After the terminal obtains the high-speed train identifier, the terminal is confirmed to be on a moving high-speed train based on its GPS location and speed. This double confirmation avoids the possibility that the terminal is merely within the high-speed train network and not on a moving high-speed train.
[0063] In the disclosed embodiment, the user's presence in a dedicated network environment can be detected by using the terminal's identification of the terminal's presence on the high-speed rail operator's dedicated network. A secondary confirmation using real-time GPS speed measurement can accurately determine whether the user is in a high-speed rail network environment or is merely accidentally present on the dedicated network.
[0064] Figure 5FIG. 1 shows a flow chart of determining network standard private network layout information according to an exemplary embodiment of the present disclosure. Figure 5 As shown, the following steps are included.
[0065] In step S31, a signal map of the line is generated based on regular offline test scanning.
[0066] In the disclosed embodiment, regular offline network testing is performed on a line to generate a signal map for the line. For example, regular offline network testing is performed to summarize the continuous base station locations of major high-speed rail lines and generate a signal map for the high-speed rail lines.
[0067] In an example of the present disclosure, the line is a line with a network standard private network layout.
[0068] In step S32, the communication capability of the terminal on the line is obtained.
[0069] In the embodiment of the present disclosure, the communication capability of the user terminal on the line is reported by means of dot reporting.
[0070] In an example of the present disclosure, when a user terminal passes through a base station, signal data of the user terminal is collected in the form of dot reporting, and the communication capability of the terminal on the line is updated in real time in the form of dot reporting.
[0071] In step S33, based on the signal map of the line and the communication capability of the terminal on the line, the network standard private network layout information of the line is obtained.
[0072] In the embodiment of the present disclosure, the network standard private network layout information of the line may be the network capability of the signal map of the line with the network standard private network layout, for example, the network capability of the signal map of the high-speed rail line.
[0073] In one example of this disclosure, regular offline network scanning tests are performed to aggregate the consecutive base stations on a line with a dedicated network layout to generate network layout information for that line. Subsequently, user terminals reporting communication capability events on that line are combined with the base stations to update the network layout information for that line and output the line's operational dedicated network capabilities.
[0074] For example, in one example of this disclosure, the network capabilities of the high-speed rail line's signal map are updated based on the communication capabilities of the terminal on the high-speed rail line. For example, the Beijing-Zhangjiakou High-Speed Railway operates a 5G high-speed rail private network throughout its entire route. The Beijing-Shanghai High-Speed Railway operates a 4G high-speed rail private network throughout its entire route, with only some sections equipped with 5G private network capabilities.
[0075] In the disclosed embodiment, through regular offline network scanning tests by the terminal and reporting by the user terminal, the private network capability coverage of the line with the network standard private network layout can be obtained, which facilitates the judgment of the most suitable network environment for the terminal on the line.
[0076] In the disclosed embodiment, based on determining that the terminal is currently on an active line with a dedicated network layout and that the current resident network is a first-standard dedicated network, such as a 4G dedicated network, combined with the dedicated network layout information on the line, it is determined that the line does not have a second-standard dedicated network, such as a 5G dedicated network.
[0077] Furthermore, in the disclosed embodiment, when the currently located first network standard private network intersects with the second network standard private network, the terminal's network will be forcibly downgraded to the first network standard private network. This approach can avoid the problem of slow network speed caused by the network selection priority defined by the 3GPP protocol, and can improve the user's Internet experience in the high-speed rail network environment.
[0078] In the disclosed embodiment, based on the determination that the terminal is currently on a route with an active private network layout and the current resident network is a private network of the second network standard, when the currently resident private network of the second network standard intersects with another network, the network selection priority defined by the original 3GPP protocol will be maintained.
[0079] A network standard selection method provided by an embodiment of the present disclosure accurately identifies the network environment in which a terminal is located on a line with a network standard private network layout through protocol information identification combined with GPS location and rate update. By referring to the network standard private network layout information of the line, the signal quality of the line is perceived in advance, and the optimal network suitable for the terminal is selected, thereby avoiding the problem of slow network speed caused by the network selection priority defined by the 3GPP protocol, and can improve the user's Internet experience in the high-speed rail network environment.
[0080] In the embodiments of the present disclosure, the line is a high-speed rail line. A line is a route with a network-standard private network layout, for example, a high-speed rail line: the Beijing-Zhangjiakou High-Speed Rail Line, the Beijing-Shanghai High-Speed Rail Line, etc.
[0081] In one example of the present disclosure, the high-speed rail private network is the China High-Speed Rail Network, an information service platform using the Internet as a medium, and refers to a network covering a specific area. The public network is a public communication network.
[0082] The method for selecting a network standard involved in the present disclosure is described below with reference to embodiments.
[0083] The embodiments of the present disclosure are described below using a high-speed rail line as an example, and the network standard private network includes a 4G high-speed rail private network and a 5G high-speed rail private network.
[0084] Figure 6FIG. 1 shows a flow chart of a network standard selection method according to an exemplary embodiment of the present disclosure. Figure 6 As shown, the following steps are included.
[0085] In step S40, the resident network is determined.
[0086] In an example of the present disclosure, a network in which the terminal currently resides is determined.
[0087] In step S41, it is determined whether there is a high-speed rail logo.
[0088] In the embodiment of the present disclosure, based on the message report, it is checked whether there is a high-speed rail logo.
[0089] For example, in an example of the present disclosure, if the resident network is a high-speed rail private network, the terminal is notified via RRC reconfiguration with the HST identifier. The terminal checks whether there is a high-speed rail identifier based on the message.
[0090] In an example of the present disclosure, if the resident network does not have a high-speed rail identification, the terminal is not within the range of the high-speed rail private network, and then steps S47 and S48 are executed.
[0091] In step S42, GPS high-speed rail speed is measured.
[0092] In the embodiment of the present disclosure, whether the high-speed rail is in motion is determined based on GPS high-speed rail speed measurement.
[0093] In the disclosed embodiment, if the high-speed rail is in motion, that is, the speed obtained by GPS speed measurement is within the high-speed rail speed range, step S43 is executed.
[0094] In step S43, it belongs to the high-speed rail private network state.
[0095] In the embodiment of the present disclosure, if the message is reported and it is determined that the terminal is within the high-speed rail range, and the GPS speed measurement determines that it is within the high-speed rail speed range, then it is determined that the terminal is in the high-speed rail private network state.
[0096] In step S44, whether to reside in the 4G high-speed rail private network.
[0097] In an example of the present disclosure, based on the high-speed rail identifier, it is determined whether the network where the terminal resides belongs to a 4G high-speed rail private network. If it belongs to a 4G high-speed rail private network, step S45 is executed.
[0098] In an example of the present disclosure, if the network where the terminal resides does not belong to the 4G high-speed rail private network, if it is a 5G private network, the network selection priority strategy defined by the original 3GPP network selection protocol is maintained.
[0099] In step S45, the high-speed rail signal map is checked to see whether there is a 5G high-speed rail private network.
[0100] In one example of this disclosure, regular offline network scanning tests are performed to aggregate the continuous base stations along a high-speed rail line and generate a signal map for that line. Subsequently, communication capability events reported by user terminals on the high-speed rail are combined with the base stations to update the network capabilities of the high-speed rail line signal map and output the capabilities of the 4G or 5G high-speed rail operating private network for that line.
[0101] In an example of the present disclosure, based on the private network capability of the signal map, it is checked whether there is a 5G private network. If there is a 5G private network, step S49 is executed.
[0102] In an example of the present disclosure, if there is no 5G private network, step S46 is executed.
[0103] In step S46, the 4G network standard is forced.
[0104] In the disclosed embodiment, if the current network range of the terminal is a 4G private network and there is no 5G private network on the high-speed rail line, it will be forced to downgrade to a 4G private network when intersecting with other levels of networks.
[0105] In step S47, the 5G network is restored first.
[0106] In an example of the present disclosure, when the message report does not have a high-speed rail identification, restoring the 5G network is prioritized.
[0107] In step S48, exit the high-speed rail private network.
[0108] In an example of the present disclosure, when the message report does not have a high-speed rail identification, the 5G network is restored first and the high-speed rail private network is exited.
[0109] In step S49, the 5G network is restored first.
[0110] In an example of the present disclosure, when the network range to which the resident terminal belongs is a 5G private network, restoring the 5G network takes priority.
[0111] The method for selecting a network mode provided by the embodiment of the present disclosure accurately obtains the current high-speed rail status of the terminal through high-speed rail identification and GPS speed measurement, and understands the distribution of the high-speed rail private network in real time based on the signal map determined by offline network scanning and the communication capability of the user terminal. It can accurately select the optimal high-speed rail operation private network to reside, reduce the interference of frequent high-level public network signals, and can not only improve the user's optimal Internet experience in the high-speed rail network environment, but also reduce the loss caused by frequent switching.
[0112] For example, Figure 7 FIG1 shows a schematic diagram of a scenario in which the optimal network for a terminal is determined based on a network standard selection method. Figure 7As shown in the figure, D is the 4G private network coverage area, E is the 4G private network coverage area, F is the 5G public network coverage area, G is the network standard private network layout information of the line with network standard private network layout, H1 is the conventional public network, and H2 is the high-speed rail private network. When the train is running, there is no intersection between the 4G private network and any network in area D. At this time, the terminal signal is good and the video is smooth. Figure 7 As shown in d1. Area E is still covered by the 4G private network, but it intersects with the 5G public network in area F. At this time, according to the network standard private network layout information of the line, as shown in Figure 7 As shown in the middle G, it can be seen that there is no 5G high-speed rail private network in this high-speed rail line, so the high-priority network is ignored and the terminal network is forced to be downgraded to the 4G high-speed rail private network in this area. At this time, the signal is good, the video is smooth, and there is no lag. Figure 7 As shown in e1.
[0113] Based on the same concept, an embodiment of the present disclosure also provides a device for selecting a network standard.
[0114] It is understandable that the device for selecting a network format provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.
[0115] Figure 8 FIG. 1 is a block diagram of a device for selecting a network standard according to an exemplary embodiment. Figure 8 The device 100 for selecting a network standard includes an acquiring unit 101 , a determining unit 102 and a processing unit 103 .
[0116] The acquiring unit 101 is configured to acquire network standard private network layout information of the corresponding line in response to determining that the terminal moves on a line having a network standard private network layout;
[0117] The determining unit 102 is used to determine the network in which the terminal is currently residing, and the network standard private network layout information is used to record the network standard private network corresponding to one or more location points on the line;
[0118] The processing unit 103 is configured to determine a target network standard based on the network standard of the current resident network and network standard-specific network layout information when the terminal moves to each of the one or more location points.
[0119] In the embodiment of the present disclosure, the processing unit 103 determines the target network standard based on the network standard of the current resident network and the network standard private network layout information in the following manner:
[0120] In this public card embodiment, if the current resident network of the terminal at the first location point is a private network of the first network standard, and based on the network standard private network layout information, it is determined that there is a second location point corresponding to a private network of the second network standard, then the terminal determines the target network standard based on the first network standard selection strategy at the second location point.
[0121] In an embodiment of the present disclosure, if the current resident network of the terminal at the first location point is a private network of the first network standard, and it is determined based on the network standard private network layout information that there is no second location point corresponding to the private network of the second network standard, then the terminal determines the target network standard based on the second network standard selection strategy at the second location point.
[0122] In one example of the present disclosure, the first location point is a location point reached earlier than the second location point when the terminal moves on the line;
[0123] In an example of the present disclosure, when the first network standard selection policy is that the first network standard private network and the second network standard private network coexist, the priority of selecting the second network standard private network as the current resident network is higher than the priority of selecting the first network standard private network as the current resident network;
[0124] In an example of the present disclosure, the second network standard selection strategy is that when the first network standard private network and the second network standard private network do not coexist, the priority of selecting the first network standard private network as the current resident network is higher than the priority of selecting the second network standard private network as the current resident network.
[0125] In the disclosed embodiment, the line corresponds to a private network identifier and a moving speed range.
[0126] In an example of the present disclosure, the acquisition unit also uses at least one of the following methods to determine that the terminal is moving on the line: determining that the current resident network is the network corresponding to the private network identifier; if the private network identifier of the corresponding line is received and the moving speed of the terminal is within the moving speed range of the line, it is determined that the terminal is moving on the line.
[0127] In an example of the present disclosure, the acquiring unit further determines the network standard private network layout information in the following manner: determining the network standard based on the network standard reported by the terminal moving on the line at one or more location points.
[0128] In one example of the present disclosure, the line is a high-speed rail line.
