Description

Technical Field

[0001] This disclosure relates to the field of vehicle-mounted Internet of Things (IoT) technology, and in particular to a 5G slicing self-detection system, a method for establishing an abnormal TAC pool, a method for using the abnormal TAC pool, and a control system. Background Technology

[0002] Many intelligent connected vehicles have now been upgraded to support 5G technology. Slicing management is a new feature introduced in 5G networks. 5G technology will implement different slice management configurations for different service needs, such as: human network slices, general IoT slices, and smart factory slices. According to the operators' 5G network plans, internet access services for 5G intelligent connected vehicles will be carried on general IoT slices, independent of human network and smart factory slices. This plan differs significantly from the 4G network plan where all types of users share all LTE base station channels.

[0003] 5G-enabled connected vehicles can only use services normally when using general IoT slices; they cannot use slices specific to the Internet of Things (IoT) or smart factories. If a 5G-enabled connected vehicle uses a non-general IoT slice in a 5G base station, even if the terminal has registered and completed PDU dialing, it will still be unable to use data functions in these areas. This is because existing mobile communication networks typically use timers on the terminal side as a protection measure to prevent terminals from being locked out after logging into abnormal networks. For example, when the number of times a terminal is rejected from logging into the same network reaches a certain value or the network side returns a specified network rejection code, the terminal starts the corresponding timer, and the terminal will be prohibited from logging into the corresponding network for a period of time. The duration of these timers is usually set from 12 minutes to 24 hours, which will significantly affect the customer experience.

[0004] However, triggering these protection mechanisms requires specific scenario conditions, which cannot be met in all current network scenarios. Summary of the Invention

[0005] To address the aforementioned issues, this application proposes a 5G slice self-detection system, a method for establishing an abnormal TAC pool, a method for using the abnormal TAC pool, and a control system.

[0006] This application proposes a 5G slicing self-detection system for detecting and establishing a TAC pool of abnormal 5G base stations, and confirming whether the terminal side has accessed an abnormal 5G base station by comparing TAC values ​​during the subsequent registration process. The system is characterized by comprising:

[0007] An abnormal TAC event monitoring program is set up on the terminal side to monitor abnormal 5G base stations. It establishes an abnormal TAC pool and provides a query interface for the network registration module to use. When the terminal accesses the abnormal 5G base station and the TAC value is found, the terminal is notified to reselect the network standard.

[0008] An abnormal TAC pool, built into the abnormal TAC event monitoring program, is used to collect the corresponding TAC value and report it to the abnormal TAC event monitoring program when a terminal accesses an abnormal 5G base station.

[0009] As an optional implementation of this application, it may also include:

[0010] The network registration management module is used to call the abnormal TAC event monitoring program to query abnormal TACs. When the abnormal TAC event monitoring program detects that the terminal has accessed an abnormal 5G base station, it reselects the network standard and initiates a registration request.

[0011] As an optional implementation of this application, it may also include:

[0012] The session management module is used to receive PDU session establishment requests from the host program and, after the PDU session is successfully established, to notify the abnormal TAC pool event monitoring program to start the verification mechanism.

[0013] As an optional implementation of this application, it may also include:

[0014] Timer T1 is used to refresh the abnormal TAC pool, ensuring that the data in the abnormal TAC pool is refreshed in a timely manner.

[0015] Timer T2 is used to lock the 4G network and, in the event of an abnormal 5G base station, to periodically fall back to the 4G base station.

[0016] As an optional implementation of this application, the timer T1 may optionally have the following application logic for timeout:

[0017] If the network registration management module continues to detect the abnormal TAC value before the timeout, timer T1 will be started to restart the timer.

[0018] After the timeout, the TAC value at the time of the exception will be removed from the exception TAC pool.

[0019] As an optional implementation of this application, the timer T2 may optionally have the following application logic for timeout:

[0020] Before the timeout, the terminal will no longer attempt to register in the 5G network through the network registration management module;

[0021] After the timeout, the terminal will attempt to register in the 5G network again through the network registration management module.

[0022] In another aspect, this application proposes a method for establishing an abnormal TAC pool, implemented based on the aforementioned 5G slice self-detection system, comprising the following steps:

[0023] The host program initiates a PDU session establishment request;

[0024] The session management module receives the request and notifies the abnormal TAC pool event monitoring program to start the verification mechanism to check whether the connection address is successful:

[0025] If the inspection is successful, the business will proceed normally.

[0026] If the verification fails, an abnormal TAC pool is established, the TAC value of this cell is added to the abnormal TAC pool, and a refresh timer T1 for that TAC is started.

[0027] The abnormal TAC pool event monitoring program notifies the network registration management module to re-register and re-establish the PDU connection.

[0028] In another aspect, this application also proposes a method for using an abnormal TAC pool, implemented based on the aforementioned 5G slice self-detection system, comprising the following steps:

[0029] The terminal initiates registration with the 5G network;

[0030] Registration begins by receiving 5G signal broadcasts and calling the abnormal TAC query interface of the abnormal TAC pool event monitoring program through the network registration management module to confirm the existence of the abnormal TAC pool:

[0031] If it does not exist, establish a PDU connection;

[0032] If it exists, check if the current abnormal TAC value exists in the abnormal TAC pool: if it does not exist, establish a PDU connection; if it exists, temporarily disable the terminal's 5G function.

[0033] The terminal connects to the 4G network, re-establishes the 4G network PDN session, and starts timer T2.

[0034] In another aspect, this application also proposes a control system, comprising:

[0035] processor;

[0036] Memory used to store processor-executable instructions;

[0037] The processor is configured to implement either the method for establishing an exception TAC pool or the method for using an exception TAC pool when executing the executable instructions.

[0038] Technical effects of the present invention:

[0039] This application automatically sets up an abnormal 5G base station TAC pool on the terminal side and confirms whether the terminal has accessed an abnormal 5G base station by comparing the TAC value. When a connected vehicle enters an abnormal 5G base station, the terminal's 5G capability is temporarily turned off, and the terminal function is locked to 4G. This prevents the terminal from entering a specific 5G slice, which would cause data service failure and ensure the availability of data connection.

[0040] It can be applied to scenarios where terminals are unable to use the network normally due to the influence of fake base stations. By setting up an abnormal TAC pool and a terminal-locked 4G timer, it ensures that the terminal maintains service availability.

[0049] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0050] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0051] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0052] In this embodiment, to address the technical shortcoming of 5G intelligent connected vehicles being locked out of the network after logging into an abnormal network, an abnormal 5G base station TAC pool is automatically set up on the terminal side. By comparing the TAC value, it is confirmed whether the terminal has accessed an abnormal 5G base station. When the connected vehicle enters an abnormal 5G base station, the terminal's 5G capability is temporarily disabled, and the terminal function is locked to 4G. This avoids the terminal entering a specific 5G slice, which would cause data service failure and ensure the availability of data connection.

[0053] Example 1

[0054] like Figure 1 As shown, this application proposes a 5G slice self-detection system for detecting and establishing a TAC pool of abnormal 5G base stations, and confirming whether the terminal side has accessed an abnormal 5G base station by comparing TAC values ​​during the subsequent registration process. The system is characterized by comprising:

[0055] An abnormal TAC event monitoring program is set up on the terminal side to monitor abnormal 5G base stations. It establishes an abnormal TAC pool and provides a query interface for the network registration module to use. When the terminal accesses the abnormal 5G base station and the TAC value is found, the terminal is notified to reselect the network standard.

[0056] An abnormal TAC pool, built into the abnormal TAC event monitoring program, is used to collect the corresponding TAC value and report it to the abnormal TAC event monitoring program when a terminal accesses an abnormal 5G base station.

[0057] The terminal establishes a session connection through a host program; this embodiment primarily uses PDU session communication. A network registration management module is configured for network registration, and a session management module is used to establish PDU session connections.

[0058] The key lies in automatically setting up a 5G base station abnormal TAC pool on the terminal side, and confirming whether the terminal has accessed an abnormal 5G base station by comparing the TAC values.

[0059] The configured abnormal TAC event monitoring program uses its built-in abnormal TAC pool to determine whether the terminal has accessed an abnormal 5G base station. When the connected vehicle enters an abnormal 5G base station, the terminal's 5G capability is temporarily turned off, and the terminal function is locked to the 4G network.

[0060] In this embodiment, the PDU session method and related protocols are not limited.

[0061] In this embodiment, the programming method and language for the abnormal TAC event monitoring program and the built-in abnormal TAC pool are not limited.

[0062] like Figure 2 The diagram shows the architecture of the abnormal TAC event monitoring program, which includes:

[0063] A PDU session establishment notification interface is used to send a PDU session establishment notification when the session management module receives a PDU session establishment request from the host program;

[0064] The verification program is used to check whether the connection to the address is successful.

[0065] An abnormal TAC query interface is provided to access the network registration management module, enabling it to determine whether abnormal TAC values ​​exist in the abnormal TAC pool.

[0066] The program architecture design is not limited in this embodiment.

[0067] As an optional implementation of this application, it may also include:

[0068] The network registration management module is used to call the abnormal TAC event monitoring program to query abnormal TACs. When the abnormal TAC event monitoring program detects that the terminal has accessed an abnormal 5G base station, it reselects the network standard and initiates a registration request.

[0069] As an optional implementation of this application, it may also include:

[0070] The session management module is used to receive PDU session establishment requests from the host program and, after the PDU session is successfully established, to notify the abnormal TAC pool event monitoring program to start the verification mechanism.

[0071] As an optional implementation of this application, it may also include:

[0072] Timer T1 is used to refresh the abnormal TAC pool, ensuring that the data in the abnormal TAC pool is refreshed in a timely manner.

[0073] Timer T2 is used to lock the 4G network and, in the event of an abnormal 5G base station, to periodically fall back to the 4G base station.

[0074] As an optional implementation of this application, the timer T1 may optionally have the following application logic for timeout:

[0075] If the network registration management module continues to detect the abnormal TAC value before the timeout, timer T1 will be started to restart the timer.

[0076] After the timeout, the TAC value at the time of the exception will be removed from the exception TAC pool.

[0077] As an optional implementation of this application, the timer T2 may optionally have the following application logic for timeout:

[0078] Before the timeout, the terminal will no longer attempt to register in the 5G network through the network registration management module;

[0079] After the timeout, the terminal will attempt to register in the 5G network again through the network registration management module.

[0080] This invention introduces an abnormal TAC refresh timer T1 and a terminal lock 4G timer T2 to provide network access verification services to the network registration management module and the session management module. The logic after timer T1 and timer T2 time out is as follows: Figure 3 and Figure 4 As shown, the specific implementation includes:

[0081] If the network registration management module continues to detect the abnormal TAC before timer T1 expires, the timer will restart; after timer T1 expires, the TAC will be removed from the abnormal TAC pool.

[0082] Before timer T2 expires, the terminal will no longer attempt to register in the 5G network. After timer T2 expires, the terminal will attempt to register in the 5G network again.

[0083] In this embodiment, to avoid the problem of vehicle-mounted connected terminals accidentally entering the 5G network's dedicated slice and thus being unable to use data traffic, the external interface of the PDU session manager (session management module) can be set as a non-reentrant function when implementing this invention.

[0084] When implementing this invention, the duration of connection timer T1 can be set to 2 hours, meaning that if the abnormal TAC does not re-enter the pool within 120 minutes, it will be removed from the abnormal TAC pool. The duration of timer T2 can be set to 600 seconds, meaning that after 600 seconds, the terminal will attempt to register again on the 5G network.

[0085] The abnormal TAC refresh timer T1 can keep the data in the abnormal TAC pool updated in a timely manner, preventing the terminal from being unable to access the repaired network due to the terminal not updating in time after network-side optimization and transformation; the terminal lock 4G timer T2 can allow the terminal to fall back to the 4G base station under abnormal 5G base station, ensuring the availability of data services, while also returning to the 5G network in a timely manner, preventing the terminal from staying on the 4G base station for a long time.

[0086] The functions of the session management module and the network registration management module can be combined with the appendix. Figure 1 The description of the cross-armor is not repeated in this embodiment.

[0087] The modules or steps of the present invention described above can be implemented using general-purpose computing devices. They can be centralized on a single computing device or distributed across a network of multiple computing devices. Optionally, they can be implemented using computer-executable program code, thereby storing them in a storage device for execution by a computing device, or fabricating them separately as individual integrated circuit modules, or fabricating multiple modules or steps into a single integrated circuit module. Thus, the present invention is not limited to any particular hardware and software combination.

[0088] The implementation and application process of this solution will be described in detail below.

[0089] Example 2

[0090] like Figure 3 As shown, this application, in another aspect, proposes a method for establishing an abnormal TAC pool, implemented based on the aforementioned 5G slice self-detection system, including the following steps:

[0091] The host program initiates a PDU session establishment request;

[0092] The session management module receives the request and notifies the abnormal TAC pool event monitoring program to start the verification mechanism to check whether the connection address is successful:

[0093] If the inspection is successful, the business will proceed normally.

[0094] If the verification fails, an abnormal TAC pool is established, the TAC value of this cell is added to the abnormal TAC pool, and a refresh timer T1 for that TAC is started.

[0095] The abnormal TAC pool event monitoring program notifies the network registration management module to re-register and re-establish the PDU connection.

[0096] The process for establishing the abnormal TAC pool in the abnormal TAC pool monitoring program is as follows:

[0097] 1) After a PDU session is successfully established, the session management module notifies the abnormal TAC pool monitoring program to start a verification mechanism, such as using PING or other connection detection tools to try to verify whether the application layer connection is successful.

[0098] 2) If the verification is successful, the service continues normally. If the verification fails, the TAC value of this cell is added to the abnormal TAC pool, and a refresh timer T1 for that TAC is started.

[0099] 3) When the verification in 2) fails, the TAC value of this cell is added to the abnormal TAC pool. The abnormal TAC pool monitoring program notifies the network registration management module to re-register and re-establish the PDU session.

[0100] Example 3

[0101] In another aspect, this application also proposes a method for using an abnormal TAC pool, implemented based on the aforementioned 5G slice self-detection system, comprising the following steps:

[0102] The terminal initiates registration with the 5G network;

[0103] Registration begins by receiving 5G signal broadcasts and calling the abnormal TAC query interface of the abnormal TAC pool event monitoring program through the network registration management module to confirm the existence of the abnormal TAC pool:

[0104] If it does not exist, establish a PDU connection;

[0105] If it exists, check if the current abnormal TAC value exists in the abnormal TAC pool: if it does not exist, establish a PDU connection; if it exists, temporarily disable the terminal's 5G function.

[0106] The terminal connects to the 4G network, re-establishes the 4G network PDN session, and starts timer T2.

[0107] The usage process of the abnormal TAC pool in the abnormal TAC pool monitoring program is as follows:

[0108] 1) Before the terminal initiates registration with the network, the network registration management module will first call the abnormal TAC query interface of the abnormal TAC pool monitoring program to confirm whether the abnormal TAC pool exists. If it exists, the current TAC value will be compared with it.

[0109] 2) If the connection TAC value exists in the abnormal TAC pool, the terminal's 5G function will be temporarily disabled;

[0110] 3) The terminal connects to the 4G network, re-establishes the 4G network PDN session, and starts timer T2.

[0111] Therefore, this application avoids the situation where vehicle network terminals are unable to use data services while residing under a 5G non-vehicle-to-everything (V2X) service slice. Furthermore, it allows for rapid reuse of the 5G network after the vehicle network terminal leaves a specific area, thereby improving the stability of the vehicle-to-everything (V2X) terminal connection.

[0112] This invention can also be applied to scenarios where terminals are unable to use the network normally due to the influence of fake base stations. By setting up an abnormal TAC pool and a terminal-locked 4G timer, the availability of services for the terminal can be ensured.
