Description

Technical Field

[0001] The present invention relates to an outbound line routing system, belonging to the field of telecommunication network technology. Background Art

[0002] With the rapid development of communication technology, the telecommunication network structure has become increasingly complex, and the requirements for the line routing system have also become higher and higher. Traditional routing systems often have problems such as low resource utilization, complex management, and poor scalability. In order to adapt to this change, it is particularly important to develop an efficient, flexible, and scalable line routing system deployment solution.

[0003] In this context, the introduction of 5G technology has brought new opportunities and challenges to the telecommunication network. As an important part of the CTNet2025 network reconstruction, the 5G network incorporates the core ideas of SDN, NFV, and cloud computing in its design and has the characteristic of separation of control and bearer. The design of the 5G core network can be based on a unified NFVI resource pool and implement cloud deployment, elastic scaling, and contraction through methods such as virtual machines and containers on virtual machines. At the same time, it is conducive to providing network slicing functions conveniently and flexibly; through the sinking of the user plane function (UPF) and the virtualization of business applications, edge computing is realized.

[0004] In addition, the multi-network convergence characteristic of the 5G network requires the line routing system to be able to operate and maintain multiple different standard networks efficiently, continuously reduce operation and maintenance costs, achieve energy conservation and emission reduction, and improve competitiveness. This requires the line routing system to have a higher level of flexibility and intelligence to achieve the efficient dynamic management and coordination of multiple access networks.

[0005] At the same time, with the expansion of the network scale and the diversification of business requirements, the line routing system needs to be able to support larger-scale data processing and more complex network topologies. This not only requires the routing system to have efficient data processing capabilities but also requires the system to be able to flexibly adapt to changes in the network structure and quickly respond to new business requirements.

[0006] To achieve these goals, the line routing system may need to adopt advanced routing protocols such as BGP (Border Gateway Protocol) and IS-IS (Intermediate System to Intermediate System), which can support the routing requirements of large-scale networks, provide fast convergence times, and good scalability.

[0007] At the same time, the routing system also needs to integrate artificial intelligence and machine learning technologies to achieve more intelligent traffic management and routing optimization.

[0008] In summary, in the face of the increasingly complex telecommunications network structure, developing an efficient, flexible, and scalable line routing system is the key to meeting future communication needs. This requires the industry to continuously explore and innovate to keep pace with the development of technology. Summary of the Invention

[0044] 2.3 Dynamically allocate call tasks

[0045] Sort the lines according to the load score;

[0046] Give priority to allocating new call requests to the line with the highest load score, that is, the line with the lowest load; then allocate call tasks to each line;

[0047] 2.4 Predictive analysis and preventive measures

[0048] Use historical data to predict the load trend of each line;

[0049] If it is predicted that some lines will be overloaded, take preventive measures;

An outbound call line routing system according to claim 3, characterized in that: The specific allocation steps of the priority allocation module are as follows: 1.1 Determine the location of the called number Input: called number; Processing: the system identifies the prefix of the called number and determines its location; Output: location information of the called number; 1.2 Collecting line resource information Input: All available line resources owned by the system; Processing: Collect the following information for each line: Whether the location matches the location of the called number; call quality indicators involving voice clarity, packet loss rate, and delay; rate information based on operators, time periods, and regions; Output: detailed information list of each line; 1.3 Calculate the line priority score Processing: For each line, a priority score is calculated based on the following factors: Location matching score: If the line location matches the called number location, the score is high; Call quality score: The score is calculated based on voice clarity, packet loss rate, and latency indicators. The higher the quality, the higher the score. Cost score: The score is calculated based on the line rate. The lower the rate, the higher the score. Use the weighted sum formula to calculate the total score: Total score = w1 × location matching score + w2 × call quality score + w3 × cost score, where w1, w2, and w3 are weight coefficients, which are adjusted according to business needs; 1.4 Sort and select the highest scoring line Processing: Sort all lines according to the calculated total score; select the line with the highest score as the outbound call line; Output: selected line resources; 1.5 Execute outbound call Processing: Use the selected line resources to perform outbound call operations; Output: outbound call execution result. 1.6 Feedback and Optimization Processing: Collect feedback information on outbound call execution, including actual call quality and customer feedback; The weight coefficients w1, w2, and w3 are adjusted according to the feedback to optimize the line selection strategy.

5. An outbound call line routing system according to claim 3, characterized in that: The specific allocation steps of the load balancing module are as follows: 2.1 Real-time monitoring of line load Input: The current load of each line, including call volume, connection rate, and number of concurrent calls; Processing: Collect and update the above indicators in real time; Output: load status of each line; 2.2 Calculating Line Load Score Calculate the load score based on the current load condition of the line; The load score is calculated using the following formula: The current load is an indicator of call volume or concurrent call count. The higher the load, the lower the score; the lower the load, the higher the score. The load score of each line is then output. 2.3 Dynamically allocate call tasks Sort the lines by load score; Prioritize allocating new call requests to the line with the highest load score, i.e. the line with the lowest load; then allocate call tasks to each line; 2.4 Predictive analysis and preventive measures Use historical data to predict the load trend of each line; If overloading of certain lines is predicted, take preventive measures; 2.5 Execute outbound calls and monitor the results Use the selected line to perform outbound call operations and monitor the outbound call results in real time; then output the outbound call execution results and line load changes. 2.6 Feedback and Optimization Collect feedback information on outbound call execution, including actual call quality and line load changes; The parameters in the load score calculation formula are adjusted based on the feedback to optimize the line selection strategy.

6. An outbound call line routing system according to claim 3, characterized in that: The specific working steps of the fault switching and retry module are as follows: 3.1 Fault Detection Heartbeat detection: monitors the health status of each line by sending heartbeat signals regularly. If no response is received within the set time, the line is considered to be faulty. Resource usage monitoring: monitors the usage of system resources to identify potential failure points; Performance baseline comparison: Compare the current system performance with the baseline during normal operation to detect performance degradation or anomalies; 3.2 Quickly identify faults Real-time monitoring: Use heartbeat detection to monitor line status in real time. Once the main line is found to be faulty or the connection is unstable, it will be identified immediately. 3.3 Intelligent Switching Backup line selection: During a failover, calls are quickly transferred to backup lines based on the preset backup line list and switching rules; Fault line record: record the information of the fault line for subsequent troubleshooting and repair; 3.4 Retry after failure For failed call requests, retry according to the set retry strategies; these strategies include trying to reconnect at different time periods and adjusting call parameters to improve the connection rate; 3.5 Retry limit Maximum number of retries: Set the maximum number of retries for each task to avoid resource exhaustion caused by infinite retries; 3.6 Fault recovery process Fault isolation: Once a fault is detected, the fault recovery process is initiated, including multiple steps such as fault isolation, traffic transfer, and service restart; Automatic execution: Fault recovery is automatically executed through pre-set policies; 3.7 Data backup and recovery Regular backup: Ensure data security and consistency by automatically backing up data regularly and restoring data from a suitable recovery point when a failure occurs; 3.8 Monitoring and Testing Continuous monitoring: Provides real-time health status and performance indicators of components and issues early warnings when signs of failure occur; Regular testing: Test the failover process regularly.

7. The outbound call line routing system according to claim 3, characterized in that: The specific working steps of the compliance and anti-sealing module are as follows: 4.1 Number Pool Management Number pool construction: Build a number pool that includes different operators, different regions, and different time periods to ensure the compliance and security of outgoing calls; Number allocation strategy: Based on the needs of the call task, the system dynamically allocates numbers from the number pool to avoid the risk of frequent outgoing calls from a single number; Number recycling mechanism: For used numbers, the system will recycle them to the number pool after a preset time so that they can be used again; 4.2 Call frequency control Set frequency limit: The system sets the call frequency limit for each number according to compliance requirements; Real-time monitoring and adjustment: The system monitors the call frequency of each number in real time. Once it approaches or exceeds the limit, it automatically reduces the outgoing call speed or suspends the outgoing call task; Calculation formula: Use the Irish B formula in queuing theory to estimate the maximum number of calls that the system can handle under a given call frequency and number of numbers to ensure that it does not exceed the operator's blocking threshold; the Irish B formula is as follows: in, A is the average number of customers in the system, λ is the arrival rate, μ is the service rate, and ρ is the traffic intensity or server utilization; 4.3 User Feedback Processing Real-time monitoring: The system monitors user feedback in real time; Feedback classification: Categorize user feedback; Processing measures: Take corresponding measures for different types of feedback; User communication: For users with contact information, we will conduct return visits and communication to understand the details and provide solutions; for users who have not left contact information, we will guide them to provide feedback through official channels; 4.4 Dynamic Adjustment Strategy Data analysis: Regularly analyze number usage and user feedback data to identify potential compliance risks; Policy optimization: Based on the analysis results, dynamically adjust number allocation policies and call frequency limits to adapt to changing compliance requirements and user needs. Risk warning: Establish a risk warning mechanism to adjust strategies in a timely manner when potential compliance risks are detected to avoid account suspension or other adverse consequences.
