Description

Technical Field

[0001] This invention relates to railway-specific communication technology, and in particular to a method and system for maintaining functional number consistency in a 5G-R and GSM-R multi-mode railway-specific terminal. Background Technology

[0002] Function addressing is a method in communication systems (such as GSM-R and 5G-R railway communication systems) that uses function numbers instead of physical addresses or MSISDN numbers to contact users. Its core principle is based on the user's functional role. For example, in a railway system, if a dispatcher wants to contact the driver of a specific train, they don't use the driver's personal mobile phone number or the locomotive's physical equipment number, but rather the driver's function number corresponding to the driver's role or the train's function number corresponding to the train number. Function numbers play a crucial role in train dispatching and command. Dispatchers can communicate quickly and accurately with train drivers through function numbers, which helps ensure the safe and efficient operation of trains and maintains railway transport order.

[0003] Function number synchronization refers to the process of aligning the function number information in GSM-R and 5G-R networks with the service information of terminal equipment in the railway operation system. Only when the function numbers are synchronized can accurate communication be ensured.

[0004] In the current construction of 5G-R railway communication systems, long-term coexistence with GSM-R communication systems is inevitable, leading to various complex situations such as overlapping and complementary coverage. To adapt to this network environment, multi-mode terminal devices supporting both GSM-R and 5G-R are required. Current technical solutions have separately developed 5G-R and GSM-R function number synchronization schemes. The network system equipment of the two communication systems is independent, lacking a unified and coordinated function synchronization processing mechanism. Existing technologies in this field have the following problems: First, multi-mode terminals process the function numbers of the 5G-R and GSM-R systems independently without discrimination, requiring the simultaneous display of both function numbers and their corresponding identity information. This results in complex information display, and operations such as function number registration, deregistration, querying, and switching are cumbersome and inefficient. Secondly, when the network status changes, multi-mode terminals simultaneously perform operations such as function number synchronization queries on two networks, resulting in significant service overhead. This is particularly noticeable in areas where 5G-R and GSM-R overlap and network status changes occur. Finally, during network handover, the function number update operation by staff may take some time, causing prolonged function addressing of service terminals and affecting the efficiency of the scheduling communication system.

[0005] It should be noted that the information disclosed in the background section above is only for understanding the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The main objective of this invention is to overcome the deficiencies in the aforementioned background technology and provide a method and system for maintaining functional number consistency in 5G-R and GSM-R multi-mode railway dedicated terminals.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A method for maintaining functional number consistency in a 5G-R and GSM-R multi-mode railway dedicated terminal includes the following steps: S1. The function number business application module receives operation instructions initiated by the user for the function number, the operation including at least one of registration, deregistration, query and switching; S2. Determine the current network status, which includes the presence of both 5G-R and GSM-R networks, the presence of only 5G-R network, or the presence of only GSM-R network; S3. Based on the network status, process the operation command: When dual networks exist, the function number service application module integrates the operation instructions and prioritizes the use of the 5G-R network for function number synchronization processing. The 5G-R network module takes the lead in synchronizing the function number operation, while the GSM-R network module performs the function number query operation when preset conditions are met. When only a 5G-R network exists, the function number service application module processes the operation according to the 5G-R single network logic. When only a GSM-R network exists, the function number service application module processes the operation according to the GSM-R single-network logic. S4. The function number business application module collects function number status information; S5. The function number display interface shows the registration status of the function number by combining a single function number with 5G-R and GSM-R network tags; S6. When a network handover is detected, a function number synchronization operation is performed based on the pre-set and stored function number information to ensure the consistency and availability of the function number before and after the handover in different network environments.

[0008] Furthermore, in step S3, when both networks exist, the priority activation of the 5G-R network for function number synchronization includes: the 5G-R network module is responsible for real-time monitoring and synchronization of function number status information to ensure the consistency of function number data and service continuity between 5G-R and GSM-R.

[0009] Furthermore, the function number query operation performed by the GSM-R network module in step S3 when the preset conditions are met includes: performing the query operation when it is necessary to update the function number status of the GSM-R network, specifically including: when the GSM-R network is initially accessed or when it resumes connection from a disconnected state; when the GSM-R network module fails to synchronously obtain the operation result after the 5G-R network module completes the function number registration, deregistration or switching operation; and when the GSM-R network module detects that its stored function number status is lost or incorrect.

[0010] Furthermore, the converged operation instruction mentioned in step S3 means that when a user performs an operation, the terminal simultaneously executes the corresponding function number operation in both the 5G-R and GSM-R networks, reducing the number of user operation steps.

[0011] Furthermore, step S4 involves collecting the function number status information, which includes collecting the function number status from the 5G-R network and the GSM-R network, and organizing and associating the information.

[0012] Furthermore, the display in step S5 includes: displaying a single function number and simultaneously displaying 5G-R and GSM-R network tags, wherein the network tags indicate the registration status of the function number in its respective network.

[0013] Furthermore, the network switching action in step S6 includes at least one of switching from a 5G-R network to a GSM-R network, switching from a GSM-R network to a 5G-R network, or switching from a dual-network to a single-network.

[0014] Furthermore, the function number synchronization operation in step S6 includes: performing synchronization based on pre-stored function number information according to the network characteristics after the switch, so as to seamlessly connect communication service requirements.

[0015] Furthermore, the function number operation is initiated by the user through the terminal interface, and the function number service application module uniformly manages the operation of 5G-R and GSM-R function numbers.

[0016] A 5G-R and GSM-R multi-mode railway dedicated terminal system includes: a function number service application module, a 5G-R network module, a GSM-R network module, and a function number display interface; The function number service application module is configured as follows: - Receive user-initiated operation instructions for a function number, the operation including at least one of registration, deregistration, query and switching; - Determine the current network status, which includes the presence of both 5G-R and GSM-R networks, the presence of only 5G-R network, or the presence of only GSM-R network; - Process the operation command based on the network status: When dual networks exist, the operation instructions are merged, and the 5G-R network module is given priority to perform function number synchronization processing. The 5G-R network module takes the lead in synchronizing the function number, while the GSM-R network module performs function number query operation when necessary. When only a 5G-R network exists, the operation is processed according to the 5G-R single-network logic. When only a GSM-R network exists, the operation is processed according to the GSM-R single-network logic. - Collect function number status information; - When a network handover is detected, a function number synchronization operation is performed based on the pre-set and stored function number information to ensure the consistency and availability of the function number before and after the handover in different network environments; The function number display interface is configured to display the registration status of the function number by combining a single function number with 5G-R and GSM-R network tags.

[0017] The present invention has the following beneficial effects: This invention provides a method and system for maintaining consistent function numbers in 5G-R and GSM-R multi-mode railway dedicated terminals. For scenarios where 5G-R and GSM-R railway communication systems coexist, an innovative function number management scheme is proposed, which effectively meets the core requirements for efficient, stable, and intelligent management of function numbers in this scenario.

[0018] In terms of human-computer interaction and information display, this invention deeply integrates the registration, deregistration, query, and switching operations of dual-network function numbers through a unified management model centered on function number applications. This allows multi-mode terminals to display only a single function number and its corresponding identity information, significantly reducing the complexity of displayed information. Simultaneously, users do not need to focus on network switching details, but only on function number-related operations, significantly simplifying the operation process and improving efficiency. Regarding network resource utilization and service continuity assurance, this invention demonstrates outstanding advantages: when both networks exist simultaneously, the 5G-R network is the primary driver, with the GSM-R network playing a secondary role in function number synchronization. This fully leverages the rich services and strong processing capabilities of the 5G-R communication system, effectively reducing the service overhead of the GSM-R network. Even if the network status changes, multi-mode terminals do not need to repeatedly perform synchronization query operations on both networks, further optimizing network efficiency. In network switching scenarios, this invention can significantly improve the efficiency of service switching during network switching: the system automatically performs synchronization operations based on the function number information pre-stored on the machine, without the need for staff to manually update the function number, which not only speeds up the switching speed of function number addressing services, but also effectively ensures the stability and reliability of the railway dispatching communication system.

[0019] Overall, the solution of this invention not only achieves unified management of 5G-R and GSM-R function numbers, but also optimizes multiple dimensions such as operation logic, resource consumption, and switching efficiency, significantly improving the efficiency and reliability of multi-mode terminal function number synchronization, providing strong support for the smooth operation of railway communication systems during the dual-network transition phase, and has significant practical value.

[0020] Other beneficial effects of the embodiments of the present invention will be further described below. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] This invention aims to address the problems of fragmented function number management, cumbersome operation, high service overhead, and service interruption during network switching caused by the differences in the dual-network architecture of 5G-R and GSM-R railway communication systems during the long-term coexistence of these two networks. It proposes a unified management scheme centered on the function number service application module. This scheme integrates dual-network function number operation, differentiated processing based on network status (dual-network / single-network) (5G-R-led synchronization and GSM-R on-demand assistance in dual-network scenarios, and automatic adaptation to corresponding logic in single-network scenarios), and automatic synchronization based on pre-stored information during network switching. This achieves consistent function number maintenance, simplifies human-computer interaction, reduces network service overhead, and ensures stable railway dispatch communication.

[0030] See Figures 1 to 4 This invention provides a method for maintaining consistent function numbers in a 5G-R and GSM-R multi-mode railway dedicated terminal, comprising the following steps: Step S1. The function number business application module receives operation instructions initiated by the user for the function number, the operation including at least one of registration, deregistration, query and switching.

[0031] Step S2. Determine the current network status, which includes the presence of both 5G-R and GSM-R networks, the presence of only 5G-R network, or the presence of only GSM-R network.

[0032] Step S3. Based on the network status, process the operation command: When both networks exist, the function number service application module integrates the operation command and prioritizes the use of the 5G-R network for function number synchronization processing, wherein the 5G-R network module dominates the function number synchronization operation, and the GSM-R network module performs the function number query operation when preset conditions are met; when only the 5G-R network exists, the function number service application module processes the operation according to the 5G-R single-network logic; when only the GSM-R network exists, the function number service application module processes the operation according to the GSM-R single-network logic.

[0033] In some embodiments, when dual networks exist in step S3, the priority activation of the 5G-R network for function number synchronization processing includes: the 5G-R network module is responsible for real-time monitoring and synchronization of function number status information to ensure the consistency of function number data and service continuity between 5G-R and GSM-R.

[0034] In some embodiments, the function number query operation performed by the GSM-R network module in step S3 when the preset conditions are met includes: performing the query operation when it is necessary to update the function number status of the GSM-R network, specifically including: when the GSM-R network is initially accessed or when it resumes connection from a disconnected state; when the GSM-R network module fails to synchronously obtain the operation result after the 5G-R network module completes the function number registration, deregistration or switching operation; and when the GSM-R network module detects that its stored function number status is lost or incorrect.

[0035] In some embodiments, the converged operation instruction in step S3 means that when a user performs an operation, the terminal simultaneously executes the corresponding function number operation in the 5G-R and GSM-R networks, reducing the number of user operation steps.

[0036] Step S4. The function number business application module collects function number status information.

[0037] In some embodiments, collecting function number status information in step S4 includes collecting the status of the function number from the 5G-R network and the GSM-R network, and organizing the associated information.

[0038] Step S5. The function number display interface displays the registration status of the function number by combining a single function number with 5G-R and GSM-R network tags.

[0039] In some embodiments, the display in step S5 includes: displaying a single function number and simultaneously displaying 5G-R and GSM-R network tags, wherein the network tags indicate the registration status of the function number in its respective network.

[0040] Step S6. When a network handover is detected, perform a function number synchronization operation based on the pre-set and stored function number information to ensure the consistency and availability of the function number before and after the handover in different network environments.

[0041] In some embodiments, the network switching action in step S6 includes at least one of switching from a 5G-R network to a GSM-R network, switching from a GSM-R network to a 5G-R network, or switching from a dual-network to a single-network.

[0042] In some embodiments, performing the function number synchronization operation in step S6 includes: performing synchronization based on pre-stored function number information according to the network characteristics after the switch, so as to seamlessly connect communication service requirements.

[0043] In some embodiments, the function number operation is initiated by the user through the terminal interface, and the function number service application module uniformly manages the operation of 5G-R and GSM-R function numbers.

[0044] This invention also provides a 5G-R and GSM-R multi-mode railway dedicated terminal system, including a function number service application module, a 5G-R network module, a GSM-R network module, and a function number display interface. The function number service application module is configured to: receive user-initiated operation commands for function numbers, the operations including at least one of registration, deregistration, query, and switching; determine the current network status, the network status including the presence of both 5G-R and GSM-R networks, the presence of only a 5G-R network, or the presence of only a GSM-R network; process the operation commands based on the network status: when both networks exist, merge the operation commands and prioritize enabling the 5G-R network module for function number synchronization processing, wherein the 5G-R network module leads the function number synchronization operation, and the GSM-R network module performs function number query operations when necessary; when only a 5G-R network exists, process the operation according to 5G-R single-network logic; when only a GSM-R network exists, process the operation according to GSM-R single-network logic; collect function number status information; when a network switching action is detected, perform function number synchronization operations based on pre-set and stored function number information to ensure the consistency and availability of function numbers before and after switching in different network environments. The function number display interface is configured to display the registration status of the function number by combining a single function number with 5G-R and GSM-R network tags.

[0045] The main technical advantages of the method and system proposed in this invention are as follows: For scenarios where 5G-R and GSM-R railway communication systems coexist, unified management of function numbers across both networks is achieved by using a function number service application module as the core. By integrating operations such as registration, deregistration, querying, and switching, multi-mode terminals only need to display a single function number, eliminating the need for users to focus on network switching and significantly simplifying human-computer interaction. In a dual-network environment, 5G-R prioritizes function number synchronization, while GSM-R performs queries on demand, fully leveraging the processing advantages of 5G-R to reduce GSM-R network service overhead. During network switching, automatic synchronization based on pre-stored function number information is achieved without manual intervention, effectively ensuring the stability and business continuity of railway dispatch communication and comprehensively improving the efficiency and reliability of function number management.

[0046] The features, implementation process, and technical advantages of specific embodiments of the present invention are further described below.

[0047] A method and system for synchronizing function numbers in a 5G-R and GSM-R multi-mode railway-specific terminal is presented. This addresses issues arising from the long-term coexistence of 5G-R and GSM-R networks, such as fragmented function number management, poor synchronization, cumbersome user operations, and service interruptions during network switching. These problems stem from the differences in dual-network architecture (GSM-R is circuit-switched, 5G-R is packet-switched). The solution constructs a comprehensive end-to-end solution encompassing unified management, state-based processing, intelligent synchronization, and intuitive display, achieving consistent maintenance of function numbers and seamless service integration across different network environments. The method uses the function number service application module as the core scheduling hub, establishing a closed-loop processing mechanism from receiving operation commands and identifying network status to synchronous execution and status presentation. This mechanism adapts to both transitional scenarios with dual-network coexistence and the deployment requirements of terminals operating independently on a single network. Within the terminal equipment system architecture, unified function number operation management is implemented, merging the registration, deregistration, query, and switching operations of 5G-R and GSM-R function numbers. Users only need to perform one operation, and the terminal will simultaneously register, deregister, query, and switch function numbers in both 5G-R and GSM-R networks based on network conditions, reducing the number of steps required for users.

[0048] Figure 1This is a schematic diagram illustrating the operation process of the 5G-R and GSM-R multi-mode railway dedicated terminal function number according to an embodiment of the present invention. The diagram shows the complete process from the user initiating a function number operation (registration, deregistration, query, switch), to the function number service application module receiving the instruction, determining the network status, and then processing the operation and collecting function number status information based on three different states: dual network existence, 5G-R network existence only, or GSM-R network existence only. Specifically, first, the user initiates a function number operation, including registration, deregistration, query, and switch, and then the function number service application module receives the operation instruction. Next, the process enters the stage of determining the current network status. At this point, three different processing branches will occur depending on the actual network conditions: If both 5G-R and GSM-R networks exist simultaneously, the function number service application module first merges and processes the operation commands. Then, the 5G-R network module takes the lead in synchronizing the function number operation, while the GSM-R network module assists in synchronizing the function number operation (and may perform queries if necessary). After the function number operations of each network are completed, the function number service application module will collect the function number status information of both networks. If only a 5G-R network exists, the function number service application module processes the user-initiated operation according to the logic of a single 5G-R network. After processing, it collects the function number status information. If only a GSM-R network exists, the function number service application module processes the relevant operations according to the logic of a single GSM-R network. After processing, it collects the function number status information. This scenario-specific processing method can adapt to different network environments, orderly advance the function number operation, and complete the collection of status information. When the environment consists of only a 5G-R network or a single GSM-R network, the system automatically adapts to and follows the inherent logic and technical specifications of the corresponding single network, independently and accurately executing the function number synchronization service. It does not require additional access to the processing resources of another network, nor does it require users to manually adjust the operation logic. This ensures the normal use and stable operation of the function number under a single network condition, effectively avoiding adverse situations such as function number management chaos or service interruption that may be caused by a single network environment.

[0049] Figure 2This is a schematic diagram illustrating the processing and display flow of function number status information for 5G-R and GSM-R multi-mode railway dedicated terminals according to an embodiment of the present invention. The diagram shows the process by which the function number service application module acquires and organizes the function number status information of the 5G-R and GSM-R networks, then transmits the associated information to the function number display interface, and finally displays the registration status in a combination of a single function number and dual network tags. Specifically, the function number service application module first acquires the function number status information of the 5G-R and GSM-R networks; then, it organizes this acquired 5G-R and GSM-R function number status information, clarifying the associated logic; then, it transmits the organized and associated information to the function number display interface; finally, the function number display interface intuitively displays the registration status of the function number under dual networks in the form of a single function number combined with 5G-R and GSM-R network tags. The function number display interface uses a combination of a single function number and a network tag to accurately and efficiently present the registration status of the function number. The two tags correspond to the 5G-R and GSM-R networks respectively, and the tag status directly indicates the registration result of the function number in the corresponding network (e.g., registered, not registered). This design not only conveys complex dual-network registration status information to users in a simple and intuitive way, but also significantly improves information delivery efficiency, reduces the time and effort cost for users to obtain key information, thereby optimizing the user experience and ensuring that users can quickly and accurately grasp the actual registration status of the function number under dual networks.

[0050] Figure 3This diagram illustrates the function number synchronization process in a 5G-R and GSM-R dual-network environment according to an embodiment of the present invention. It shows the logic of dual-network collaborative synchronization when both networks are deployed and connected simultaneously. Specifically, the system first determines whether the 5G-R network is needed to perform a query operation, thus achieving dual-network collaborative synchronization. If so, the system prioritizes the 5G-R network for function number synchronization. Next, the system determines whether the GSM-R network needs to perform a function number query operation. If so, the GSM-R network performs the query operation, and then the 5G-R network continues to lead monitoring and synchronization. If not, the 5G-R network continues to lead monitoring and synchronization. This process achieves a dual-network environment with the 5G-R network as the primary network and the GSM-R network as an on-demand auxiliary network for function number collaborative synchronization. When both 5G-R and GSM-R dual-network architectures are deployed and connected, the system prioritizes the 5G-R network for function number synchronization. This fully leverages the significant advantages of the 5G-R communication system in terms of service diversity and data processing capabilities, thereby reducing the service load on the GSM-R network and optimizing overall network resource allocation efficiency. During this process, the terminal uses the 5G-R network as the primary link, responsible for real-time monitoring and synchronization of function number status information, ensuring consistency of function number data and service continuity between 5G-R and GSM-R. The GSM-R network only performs function number query operations when necessary, ultimately achieving efficient synchronization management of function numbers in the dual-network collaborative mode.

[0051] Figure 4This is a schematic diagram illustrating the function number synchronization process during 5G-R and GSM-R multi-mode railway dedicated terminal network switching according to an embodiment of the present invention. The diagram covers the steps of detecting a network switching action, determining the switching type (5G-R to GSM-R mutual switching, dual-network to single-network conversion), and performing synchronization operations based on pre-stored function number information and corresponding network characteristics to ensure function number consistency and seamless service transition. First, the system detects a network switching action and then proceeds to determine the switching type. If the switching type is 5G-R to GSM-R, the system first obtains the pre-set stored function number information and then performs function number synchronization operations based on GSM-R network characteristics. If the switching type is GSM-R to 5G-R, the system similarly first obtains the pre-set stored function number information and then performs function number synchronization operations based on 5G-R network characteristics. If the switching type is dual-network to single-network conversion (5G-R single network or GSM-R single network), the system again first obtains the pre-set stored function number information and then performs function number synchronization operations according to single-network logic. After completing the function number synchronization operations corresponding to the different handover types mentioned above, the consistency and availability of function numbers are ensured through data transmission and processing mechanisms, ultimately achieving seamless connection of communication service requirements. Specifically, at critical nodes where network handover occurs, whether switching from 5G-R to GSM-R, from GSM-R to 5G-R, or switching between dual-network and single-network operation, the system can respond rapidly. Based on the function number information pre-set and stored locally, it quickly and accurately executes function number synchronization operations without relying on additional data interaction from external networks. Simultaneously, through efficient data transmission and processing mechanisms, it not only ensures the consistency and availability of function numbers before and after handover in different network environments but also seamlessly connects communication service requirements under various network scenarios, providing users with a stable, reliable, and uninterrupted communication service experience, further significantly improving the adaptability and robustness of the entire communication system in complex network environments.

[0052] In summary, this invention provides a method and system for maintaining function number consistency in a 5G-R and GSM-R multi-mode railway dedicated terminal, and proposes an innovative function number management scheme to meet the requirements for efficient, stable, and intelligent function number management under the coexistence of 5G-R and GSM-R railway communication systems. Compared with existing technologies, the significant advantages of this invention are as follows: 1. Simplified Display Information and Human-Computer Interaction Business Logic: Terminal devices manage function numbers uniformly, with function number applications as the main body, integrating the registration, deregistration, query, and switching operations of 5G-R and GSM-R function numbers. This way, multi-mode terminals only need to display one function number and its corresponding identity information, reducing the complexity of displayed information. Users only need to perform function number-related operations and do not need to pay attention to network switching, simplifying the operation process and improving efficiency.

[0053] 2. Reduced Service Overhead: When both 5G-R and GSM-R networks exist, this invention prioritizes 5G-R and uses GSM-R as a secondary network for function number synchronization. Leveraging the rich services and powerful processing capabilities of the 5G-R communication system, the service overhead of the GSM-R network is reduced. Thus, when network conditions change, multi-mode terminals only need to perform function number synchronization queries on the 5G-R network, reducing service overhead and improving network efficiency.

[0054] 3. Improved efficiency of service switching during network handover: When a network handover occurs, this invention performs function number synchronization based on the local function number. This eliminates the need for staff to update function numbers during network handover, improving the switching speed of function number-addressed services and ensuring the stability and reliability of the scheduling communication system.

[0055] In summary, compared with the prior art, this invention not only optimizes the human-machine operation logic, reduces service overhead, and improves the efficiency of service switching when the network state changes, but also realizes the unified management of 5G-R and GSM-R function numbers, improves the efficiency and reliability of multi-mode terminal function number synchronization, and ensures the stability and reliability of the scheduling communication system, thus having significant practical value.
