Description

Technical Field

[0001] The present invention relates to the field of tariff management technology, and more specifically, to a method and system for intelligent tariff management for dynamic switching of eSIMs. Background Art

[0002] Existing eSIM rate management technologies primarily rely on comparing network selection based on a single, publicly available price list or static package information from carriers. Under complex package structures, frequent cross-network switching can easily trigger the staggered implementation of multiple billing terms, leading to the overlapping of cross-carrier rates and the unpredictable activation of advanced billing models.

[0003] Existing methods are unable to accurately predict the true cost, resulting in amplified errors in tariff assessment and an inability to provide a reliable low-cost decision-making basis for users or network strategies.

[0004] In order to solve the above problems, a technical solution is now provided. Summary of the Invention

[0019] Build a timeline of tariff rules for multiple operators based on key trigger conditions;

[0020] Perform time-series analysis on the cross-operator handover behavior of eSIM terminals between multiple operators, extracting the time points and order of cross-operator handover behavior on the timeline;

[0021] Compare and analyze the inter-operator switching behavior of eSIM terminals on the timeline with the key triggering conditions in the operator's tariff rules;

[0022] Determine whether the cross-operator switching behavior of the eSIM terminal causes the tariff rules of multiple operators to overlap on the timeline, and mark the cross-operator switching path of the eSIM terminal that forms a nonlinear superposition effect.

[0023] In a preferred embodiment, S3 is specifically:

[0024] Based on the nonlinear superposition effect of the markers, the cross-operator handover path of the eSIM terminal is extracted, and the time point of each handover and the corresponding operator's tariff rules are extracted;

[0025] Calculate the charges for each inter-operator handover path of the eSIM terminal under the corresponding operator's tariff rules based on the time point of each handover and the billing trigger conditions in the corresponding operator's tariff rules;

[0026] The charges incurred for each inter-operator handover path of the eSIM terminal under the corresponding operator's tariff rules are accumulated, and the accumulated cost of the tariff for the inter-operator handover path of the eSIM terminal is output.

[0027] In a preferred embodiment, S4 is specifically:

[0028] Collect historical consumption data of eSIM terminals, including historical traffic usage records, historical fee expenditure records, and historical cross-operator switching records;

[0029] Collect the real-time traffic usage status of the eSIM terminal, including real-time traffic usage, real-time traffic usage rate and real-time network access operator information;

[0030] Match historical consumption data with real-time traffic usage status to determine the number of cascading effects of tariff rules triggered by the eSIM terminal during the current cross-operator switching process, and determine the risk level of the cascading effect of triggering tariff rules.

[0031] In a preferred embodiment, S5 is specifically:

[0039] Based on wireless signal strength, a secondary screening is performed on the eSIM terminal inter-operator handover paths selected from the sorted results, which have the lowest cumulative tariff cost and the lowest risk level of triggering the cascading effect of tariff rules;

[0040] According to the secondary screening results, the operator switching policy of the eSIM terminal is updated, and the adjusted operator switching control instruction is output.

[0049] By extracting key trigger conditions from tariff rules within a preset time window and establishing a timeline, the temporal distribution of each operator's tariff rules can be accurately depicted. By cross-analyzing eSIM terminal switching behavior and key trigger conditions, cross-operator switching paths for eSIM terminals that produce nonlinear superposition effects can be effectively identified, enabling cost assessment of cross-operator switching paths. Combining historical consumption data with real-time traffic status, the risk level of the cascading effect of tariff rules can be assessed. Based on the cumulative cost and risk level assessment results, high-order billing model paths can be screened and the operator switching strategy of the terminal can be dynamically adjusted. This significantly reduces assessment errors caused by opaque tariff structures, improves the accuracy of switching decisions, and ensures users' cost control capabilities in complex tariff environments.

[0052] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] Example 1

[0054] Figure 1 The present invention provides a method for intelligent tariff management for dynamic switching of eSIM, which includes the following steps:

[0055] S1. Collect the tariff rules of multiple operators and extract the key trigger conditions in the tariff rules based on the preset time window;

[0056] S2. Analyze the impact of eSIM terminal inter-operator handover behavior on tariff rules based on the timeline distribution characteristics of key trigger conditions, and mark the eSIM terminal inter-operator handover paths that produce nonlinear superposition effects;

[0057] S3. Evaluate the cumulative tariff cost of the inter-operator handover path of the eSIM terminal based on the inter-operator handover path of the eSIM terminal that produces the nonlinear superposition effect;

[0058] S4. Combine the historical consumption data and real-time traffic usage status of the eSIM terminal to assess the risk level of the cascading effect of tariff rules triggered by the cross-operator switching behavior of the eSIM terminal;

[0059] S5. Based on the evaluation results of the cumulative cost and the risk level, select the high-level billing model path;

[0060] S6. Based on the high-order billing mode path screening result, adjust the operator switching strategy of the eSIM terminal.

[0061] S1. Collect the tariff rules of multiple operators and extract the key trigger conditions in the tariff rules based on the preset time window, including:

[0062] Collect the tariff rules of multiple operators within a preset time window;

[0063] Specifically, the operator's tariff rule data within a specified preset time window is obtained from the official websites of different operators or the data interfaces provided by the operators through the network interface. The tariff rule data includes traffic tariff packages, traffic billing steps within traffic tariff packages, speed limit conditions after traffic exceeds the quota of traffic tariff packages, additional traffic billing rules after exceeding the quota, rules for preferential or free traffic for specific applications, tariff change rules after traffic usage reaches a specified threshold, and time information for the effectiveness and termination of the corresponding billing rules. The collection operation is implemented through data interface access, and a request is sent using a unified data request format to obtain the returned tariff rule data.

[0064] Segment the tariff rules according to the preset time window, and extract the effective start and end time and billing trigger conditions of each operator's tariff rules within each preset time window;

[0065] Specifically, the tariff rule data obtained from multiple operators are segmented and analyzed and processed according to preset time windows. A complete billing cycle is divided into several continuous time segments, which are preset time windows. Each time window corresponds to a fixed time length. For example, twenty-four hours is the length of a time window. The effective time and expiration time of each specific rule specified in the tariff rules provided by each operator are matched and compared with each of the above preset time windows. If the effective time and expiration time of a specific tariff rule fall completely or partially within a preset time window, it is determined that the tariff rule belongs to the preset time window, and the specific start and end time points of the tariff rule are recorded in the preset time window; for tariff rules that span multiple time windows, the start and end time applicable to the tariff rule in each preset time window are recorded separately.

[0066] Within each preset time window, each billing rule in all operator tariff rules belonging to the preset time window is analyzed and processed one by one to clarify the billing trigger conditions of these billing rules. Billing trigger conditions refer to events or traffic usage thresholds that cause tariff rules to change or activate. For example, when an operator's tariff rules stipulate that the tariff level or traffic billing unit price changes after a certain number of hours of continuous network stay or a specified amount of traffic usage is reached, then the continuous network stay reaching the specified number of hours or the traffic usage reaching the specified amount is the billing trigger condition. Parsing and extraction are performed by combining manual rule setting with automatic parsing, that is, first manually define the basic rules of the tariff trigger conditions, for example, a tariff change occurs when a specified amount of traffic is used, and then use the automatic parsing program to traverse the text or data description of each tariff rule, and automatically identify and extract the specific description information of the tariff rules that meet the manually defined billing trigger conditions.

[0067] Summarize the effective start and end time of each operator's tariff rules and billing trigger conditions within each preset time window, and output the key trigger conditions;

[0068] Specifically, the specific time information of the effective start and end of each operator's tariff rule and the charging trigger condition in each preset time window are summarized, and are uniquely identified by the tariff rule identification information to obtain the key trigger condition.

[0069] S2. Analyze the impact of eSIM terminal inter-operator handover behavior on tariff rules based on the timeline distribution characteristics of key trigger conditions, and mark the eSIM terminal inter-operator handover paths that produce nonlinear superposition effects, including:

[0070] Build a timeline of tariff rules for multiple operators based on key trigger conditions;

[0071] Specifically, using a timeline construction method, the start and end times of each operator's tariff rules within a specified preset time window are sorted in chronological order and represented using a unified timeline scale to form a timeline for the tariff rules. For example, the duration range from the start to the end of each tariff rule on the timeline is used as a separate segment on the timeline, representing the effective period of each tariff rule.

[0072] Perform time-series analysis on the cross-operator handover behavior of eSIM terminals between multiple operators, extracting the time points and order of cross-operator handover behavior on the timeline;

[0073] Specifically, an eSIM (embedded subscriber identity module) refers to a programmable communication identity module embedded in a mobile terminal device. It is used to load and manage network access profiles of multiple operators in the mobile terminal device through remote configuration without replacing the physical SIM card. Detailed records of cross-operator handovers of the eSIM terminal are collected, including the time of each cross-operator handover, the operator network name before the handover, and the operator network name after the handover. These detailed records of cross-operator handovers are analyzed and processed using a time series analysis method. Specifically, each cross-operator handover is sorted one by one according to the chronological order of each cross-operator handover to form a time series of cross-operator handovers. This method obtains the consecutive time points and order of cross-operator handovers on the timeline. For example, within a certain historical record period, if an eSIM terminal switches from operator A to operator B at some point in the morning of a certain day, and then switches from operator B to operator C at some point in the afternoon, the above method is used to record and mark the exact time and order of each cross-operator handover.

[0074] Compare and analyze the inter-operator switching behavior of eSIM terminals on the timeline with the key triggering conditions in the operator's tariff rules;

[0075] Specifically, the comparative analysis method is as follows: using each specific handover occurrence time point in the cross-operator handover behavior time series as a benchmark, the key trigger conditions of each operator's tariff rules on the same timeline are compared and retrieved, and each handover occurrence time point is analyzed to see whether it falls within the time period when a key trigger condition is in effect. For example, if a cross-operator handover occurs within a time period when a trigger condition for a tariff rule of operator A and a trigger condition for a tariff rule of operator B are both in effect, then the time point of the handover is determined to meet the overlap of key trigger conditions for multiple operator tariff rules.

[0076] Determine whether the cross-operator switching behavior of the eSIM terminal causes the tariff rules of multiple operators to overlap on the timeline, and mark the cross-operator switching paths of the eSIM terminal that form a nonlinear superposition effect;

[0077] Specifically, according to the results of the comparison and analysis, for each cross-operator switching behavior of the eSIM terminal, if the time point at which the cross-operator switching behavior occurs satisfies the key trigger conditions of the tariff rules of two or more operators at the same time, it is determined that the tariff rules overlap on the time axis, and the cross-operator switching path is a path that produces a nonlinear superposition effect. For example, when the eSIM terminal switches from operator A to operator B at a certain time in the morning of a specific day, and satisfies the excess traffic trigger condition in the tariff rules of operator A and the network time trigger condition in the tariff rules of operator B at the same time, the cross-operator switching path is marked as a path that produces a nonlinear superposition effect. If the cross-operator switching behavior does not satisfy the simultaneous establishment of the key trigger conditions of the tariff rules of two or more operators, it is not marked as a path that produces a nonlinear superposition effect. All cross-operator switching paths marked as producing nonlinear superposition effects are recorded uniformly to form a nonlinear superposition path set.

[0078] The nonlinear superposition effect refers to when the eSIM terminal performs cross-operator network switching operations, the key trigger conditions of at least two operators' tariff rules are met at the same time within the same time window, so that the actual billing result is no longer equal to the simple arithmetic addition of the individual billing results of each operator, but manifests as additional cost increments or step jumps caused by threshold chain triggering, step interval crossing or preferential expiration.

[0079] S3. Evaluate the cumulative tariff cost of the inter-operator handover path of the eSIM terminal based on the inter-operator handover path that produces the nonlinear superposition effect, including:

[0080] Based on the nonlinear superposition effect of the markers, the cross-operator handover path of the eSIM terminal is extracted, and the time point of each handover and the corresponding operator's tariff rules are extracted;

[0081] Specifically, based on the eSIM terminal inter-operator switching path that forms a nonlinear superposition effect, all specific switching events in each eSIM terminal inter-operator switching path are identified. For each specific switching event, the time point information of the specific switching event is extracted, and at the same time, the target operator's tariff rules that are cut in when the specific switching event occurs are determined. For example, by analyzing the two operator names that appear consecutively in the eSIM terminal inter-operator switching path, the specific time point of switching from the previous operator's network to the next operator's network is determined, and at the same time, the tariff rules applicable to the next operator when the specific switching event occurs are recorded, including the start and end time of the operator's tariff rules, and the billing trigger conditions contained in the tariff rules.

[0082] Calculate the charges for each inter-operator handover path of the eSIM terminal under the corresponding operator's tariff rules based on the time point of each handover and the billing trigger conditions in the corresponding operator's tariff rules;

[0083] Specifically, a segmented billing calculation method is used, that is, the specific fee calculation method and fee calculation value are determined based on the tariff rules of the operator corresponding to each switching event. Specifically: based on the degree of match between the time point of each switching event and the billing trigger conditions of the corresponding operator's tariff rules, determine whether the billing trigger conditions are met. Specifically: compare the time point of each switching event with the start time and end time of the billing trigger conditions recorded in the tariff rules of the corresponding operator; through the comparison method of the time range inclusion relationship, determine whether the time point of the specific switching event completely falls within the effective time interval range of the above billing trigger conditions (that is, between the start time and the end time); if the time point of the switching event is within the effective start time of the billing trigger conditions If the time interval between the effective end time and the effective end time is within the time interval, the billing trigger condition is judged to be met; otherwise, the billing trigger condition is judged to be not met; if the billing trigger condition is met, then according to the provisions of the corresponding operator's tariff rules, the billing unit traffic price or billing unit time price given by the operator is multiplied by the specific traffic usage or network duration of the eSIM terminal during the period of stationing on the operator's network to obtain the tariff generated by the single switching event; if the billing trigger condition of the tariff rule is not met, the tariff generated by the switching event is calculated according to the basic price when the billing trigger condition is not met in the operator's tariff rule.

[0084] Accumulate the charges incurred by each inter-operator handover path of the eSIM terminal under the corresponding operator's tariff rules, and output the cumulative cost of the tariff for the inter-operator handover path of the eSIM terminal;

[0085] Specifically, the charges generated by each switching event within the inter-operator switching path of each eSIM terminal are accumulated, and the charges generated by each single switching event are added up in sequence to obtain the total charge cost required to pay for the inter-operator switching path, which is defined as the accumulated charge cost.

[0086] S4. Combine the historical consumption data and real-time traffic usage of eSIM terminals to assess the risk level of the cascading effect of tariff rules triggered by cross-operator switching of eSIM terminals, including:

[0087] Collect historical consumption data of eSIM terminals, including historical traffic usage records, historical fee expenditure records, and historical cross-operator switching records;

[0088] Specifically, historical consumption data clearly includes historical traffic usage records, historical fee expenditure records, and historical cross-operator switching records. The above historical data are read and recorded separately from the historical database of the terminal management platform. The historical traffic usage records clearly record the specific traffic usage amount and traffic usage type of the eSIM terminal during each network residence in the historical period; the historical fee expenditure records clearly record the specific fee values ​​paid by the eSIM terminal for each cross-operator switching behavior in the historical period; the historical cross-operator switching records include the specific time of each cross-operator switching behavior, the operator name before and after the switch, and the corresponding network configuration information. All historical data is stored uniformly in a structured manner.

[0089] Collect the real-time traffic usage status of the eSIM terminal, including real-time traffic usage, real-time traffic usage rate and real-time network access operator information;

[0090] Specifically, real-time traffic usage refers to the total amount of network traffic actually generated by the eSIM terminal in the time window before and after the current cross-operator switching behavior is executed, including the sum of downlink data and uplink data traffic, expressed in bits or integer multiples thereof; real-time traffic usage rate refers to the data transmission rate generated by the eSIM terminal per unit time, recording the real-time downlink rate and uplink rate respectively. Real-time network access operator information refers to the operator identity bound to the network configuration file used by the current eSIM terminal in the activated state, including but not limited to the operator number, mobile country code and network code, network type identifier (such as 4G, 5G), etc.

[0091] Match historical consumption data with real-time traffic usage status to determine the number of cascading effects of tariff rules triggered by the eSIM terminal during the current cross-operator handover process, and determine the risk level of the cascading effect of triggering tariff rules;

[0092] Specifically, the matching analysis method involves comparing the real-time data usage, real-time data usage rate, and real-time network access operator information of the eSIM terminal with historical cross-operator switching records and historical data usage records in the historical consumption data. Using a similarity analysis method, the degree of similarity between the current real-time cross-operator switching behavior and the historical cross-operator switching behavior that triggered the cascading of tariff rules is determined. The specific similarity analysis method involves calculating the difference between the values ​​of the same attributes of the real-time data usage rate, real-time data usage, and real-time network access operator information and those of the historical cross-operator switching events that triggered the cascading effect, and comparing the current cross-operator switching order with the historical cross-operator switching order to determine whether they are consistent. If the difference in data usage and data usage rate compared above does not exceed a preset allowable range, and the current cross-operator switching order is consistent with the historical cross-operator switching order, the current cross-operator switching behavior is determined to be identical to the historical cross-operator switching behavior that triggered the cascading effect, and the current cross-operator switching behavior is determined to be capable of triggering the cascading effect of the tariff rules. The cascading effect of tariff rules refers to the phenomenon that during the cross-operator switching process of eSIM terminals, the switching behavior triggers the continuous linkage of billing rules or preferential mechanisms of multiple operators, causing multiple tariff rules to be activated in sequence, cumulatively executed, or intertwined with each other, resulting in the eSIM terminal being continuously billed or losing its original discounts in a short period of time, resulting in a nonlinear increase in actual tariff expenditure.

[0093] Statistics are counted for each inter-operator switching behavior that is determined to be capable of triggering a cascading effect, and the number of cascades that trigger the cascade effect of tariff rules in the current inter-operator switching path of the eSIM terminal is obtained; three risk intervals are preset. When the number of cascades is in the first risk interval (zero to one), the risk level of the cascade effect of tariff rules caused by the inter-operator switching behavior of the eSIM terminal is low risk; when the number of cascades is in the second interval (two to three times), the risk level of the cascade effect of tariff rules caused by the inter-operator switching behavior of the eSIM terminal is medium risk; when the number of cascades exceeds the third interval (more than three times), the risk level of the cascade effect of tariff rules caused by the inter-operator switching behavior of the eSIM terminal is high risk.

[0094] S5. Based on the cumulative cost assessment results and the risk level assessment results, select high-level billing model paths, including:

[0095] Determine a threshold for the cumulative cost of each inter-operator handover path for the eSIM terminal based on the cumulative cost of the inter-operator handover path for the eSIM terminal;

[0096] Specifically, based on the historical statistical analysis method, the historical cumulative cost of all tariffs for the historical inter-operator switching path of the eSIM terminal is obtained, and the historical cumulative cost of all tariffs is statistically calculated to obtain the average value of the historical cumulative cost of all tariffs and the standard deviation of the historical cumulative cost of all tariffs; the average value plus several times the standard deviation is used as the standard for determining the tariff cumulative cost threshold, and the tariff cumulative cost threshold for each eSIM terminal inter-operator switching path is determined.

[0097] Determine the risk threshold for each eSIM terminal inter-operator handover path based on the risk level of the cascading effect of tariff rules triggered by the inter-operator handover behavior of the eSIM terminal;

[0098] Specifically, based on the risk level of the cascading effect of tariff rules triggered by cross-operator eSIM terminal switching behavior, different risk thresholds are assigned to low, medium, and high risk levels. For example, high risk level corresponds to the highest risk threshold, medium risk level corresponds to a moderate risk threshold, and low risk level corresponds to the lowest risk threshold.

[0099] Compare the cumulative tariff cost of each eSIM terminal inter-operator handover path and the risk level of the cascading effect of triggering tariff rules with the corresponding thresholds;

[0100] Screen the eSIM terminal inter-operator handover paths whose cumulative tariff costs and risk levels exceed both the cumulative tariff cost threshold and the risk threshold, and use them as high-order billing mode paths;

[0101] Specifically, the tariff cumulative cost and risk level of all eSIM terminal inter-operator switching paths are judged, and it is recorded whether each switching path satisfies both the tariff cumulative cost threshold and the risk threshold; if it is determined that the tariff cumulative cost and risk level of the eSIM terminal inter-operator switching path exceed both the tariff cumulative cost threshold and the risk threshold, the eSIM terminal inter-operator switching path is defined as a high-order billing mode path.

[0102] S6. Based on the high-order billing model path screening results, adjust the operator switching strategy of the eSIM terminal, including:

[0103] Based on the set of cross-operator handover paths currently available for eSIM terminals, remove the high-order billing mode path;

[0104] Specifically, the explicit identification information of each path in the current optional inter-operator switching path set is compared with the path identification information of the high-order billing mode path; when it is found that the path identification information of a certain inter-operator switching path is consistent with the path identification information of the high-order billing mode path, this inter-operator switching path is removed from the current optional inter-operator switching path set.

[0105] In the set of removed inter-operator handover paths, sort them according to the cumulative tariff cost of each eSIM terminal inter-operator handover path and the risk level of the cascading effect of triggering tariff rules;

[0106] Specifically, the tariff cumulative costs of each inter-operator switching path in the removed inter-operator switching path set are compared one by one, and sorted from low to high according to the comparison results; for multiple inter-operator switching paths with the same tariff cumulative cost, a second sorting is performed according to the cascading effect risk level of the triggering tariff rules of each inter-operator switching path, and the risk level sorting method is clearly that the inter-operator switching paths with low risk levels are ranked first and the inter-operator switching paths with high risk levels are ranked last, so as to obtain the inter-operator switching path sorting results.

[0107] Based on wireless signal strength, a secondary screening is performed on the eSIM terminal inter-operator handover paths selected from the sorted results, which have the lowest cumulative tariff cost and the lowest risk level of triggering the cascading effect of tariff rules;

[0108] After a comprehensive cost and risk assessment, the eSIM terminal inter-operator switching path with the lowest cumulative tariff cost and the lowest risk level of triggering the cascading effect of tariff rules is obtained. However, the actual network communication quality is directly affected by the wireless signal strength. Too low signal strength can lead to unstable communication connections, data transmission interruptions, or frequent disconnections. Therefore, through only a secondary screening of real-time signal strength, it can ensure that the selected path can achieve economic cost optimization while also meeting the technical requirements of actual network communication quality, effectively avoiding the problem of reduced network usage experience caused by low-quality network connections. Specifically, the inter-operator switching path that ranks first in the inter-operator switching path sorting results is selected, that is, the inter-operator switching path with the lowest cumulative tariff cost and the lowest risk level of triggering the cascading effect of tariff rules.

[0109] Wireless signal strength testing is performed on the inter-operator handover path with the lowest risk level of cascading effects of the lowest cumulative tariff cost and the lowest triggering tariff rule to ensure that the actual communication quality meets the minimum wireless communication quality standard. The testing method is as follows: while selecting the inter-operator handover path with the lowest risk level of cascading effects of the lowest cumulative tariff cost and the lowest triggering tariff rule, the wireless signal strength of the target operator network involved in the currently selected inter-operator handover path is monitored in real time by a wireless signal strength testing module built into the embedded user identification module terminal. During the monitoring process, the signal strength value of the target operator network is measured and recorded in real time and compared with a preset minimum allowable threshold for wireless signal strength. If the real-time measured wireless signal strength is greater than or equal to the preset minimum allowable threshold, the currently selected inter-operator handover path is confirmed to meet the technical requirements for wireless signal strength. If the real-time measured wireless signal strength is lower than the preset minimum allowable threshold, the currently selected inter-operator handover path is explicitly discarded and the next inter-operator handover path in the sorted results is selected. The above wireless signal strength testing steps are repeated until an inter-operator handover path that meets the minimum allowable threshold for wireless signal strength is obtained. The eSIM terminal inter-operator handover path obtained through secondary screening, which has the highest wireless signal strength, the lowest cumulative tariff cost, and the lowest risk level of triggering the cascade effect of tariff rules, is used as the optimal inter-operator handover path.

[0110] According to the secondary screening results, the operator switching policy of the eSIM terminal is updated, and the adjusted operator switching control instruction is output.

[0111] Specifically, an operator switching control instruction is generated based on the operator switching order, network configuration information and network duration information of the optimal inter-operator switching path; the operator switching control instruction includes each step of the operation required to implement the inter-operator switching path, including the starting operator network, target operator network, specific time point of switching execution and network configuration information, etc.; the operator switching control instruction is transmitted to the switching control module of the eSIM terminal through the communication interface for executing the actual network switching operation.
