It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.
[0052] The VPLMN network determination method provided by the embodiments of the present application can be applied to an application environment as shown in Figure 1 . The HPLMN network 102 communicates with the VPLMN network 104 through a network. A data storage system can store data required to be processed by the HPLMN network 102. The data storage system can be integrated on the HPLMN network 102, or placed on a cloud or other network server. The HPLMN network receives network performance parameters of at least one candidate visited public land mobile network (VPLMN) network at a current time, determines network priorities of the candidate VPLMN networks according to the network performance parameters of the candidate VPLMN networks and service requirements corresponding to a target terminal, and then sends the network priorities of the candidate VPLMN networks to the target terminal, so that the target terminal selects a target VPLMN network from the candidate VPLMN networks according to the network priorities of the candidate VPLMN networks.
[0053] In one embodiment, as shown in Figure 2 , a VPLMN network determination method is provided. Taking the HPLMN network 102 in Figure 1 as an example, the method comprises the following steps:
[0054] S201, receiving network performance parameters of at least one candidate visited public land mobile network (VPLMN) network at a current time.
[0055] It should be noted that when it is required to receive network performance parameters of at least one candidate VPLMN network at a current time, the following content can be included: receiving network performance parameters transmitted by a VPLMN network through a network element Nnwdaf interface at a current time.
[0056] The network performance parameters include at least one of network layer parameters, service layer parameters and device layer parameters.
[0057] As an example, the network layer parameters can include but are not limited to cell load rate, radio resource utilization rate, etc.; the service layer parameters can include but are not limited to end-to-end delay, packet loss rate, etc.; and the device layer parameters can include but are not limited to base station available transmission bandwidth, core network element processing delay, etc.
[0058] It is further illustrated that the VPLMN network can collect the network performance parameters of the VPLMN network through a pre-deployed NWDAF collection module; the NWDAF collection module can collect the VPLMN network according to a pre-set collection frequency, and the specific value of the collection frequency can be set or adjusted according to the historical experience and actual situation of the operation and maintenance personnel, and the collection frequency is not limited herein.
[0059] In an embodiment of the present application, the VPLMN network collects the network performance parameters of the VPLMN network through a pre-deployed NWDAF collection module with a pre-set collection frequency, and transmits the collected network performance parameters to the HPLMN network through an Nnwdaf interface.
[0060] S202, determining the network priority of each candidate VPLMN network according to the network performance parameters of each candidate VPLMN network and the service demand corresponding to the target terminal.
[0061] It should be noted that when the network priority of each candidate VPLMN network is determined according to the network performance parameters of each candidate VPLMN network and the service demand corresponding to the target terminal, the following content can be included: determining the service adaptation degree score between each candidate VPLMN network and the service demand; determining the performance parameter score of each candidate VPLMN network according to the network performance parameters of each candidate VPLMN network; and determining the network priority of the corresponding candidate VPLMN network according to the performance parameter score of each candidate VPLMN network and the service adaptation degree score corresponding to the corresponding candidate VPLMN network.
[0062] S203, sending the network priority of each candidate VPLMN network to the target terminal, so that the target terminal selects a target VPLMN network from each candidate VPLMN network according to the network priority of each candidate VPLMN network.
[0063] It should be noted that the HPLMN network can generate a SoR instruction according to the network priority of each candidate VPLMN network, and then push the SoR instruction to the target terminal in real time through a control plane interface (an interface between the AMF network element of the HPLMN network and the target terminal).
[0064] In an embodiment of the present application, the HPLMN network generates a SoR instruction according to the network priority of each candidate VPLMN network, sends the SoR instruction to the target terminal, and the target terminal displays the network priority of each candidate VPLMN network on the touch display screen of the target terminal. The target user selects a target VPLMN network from the candidate VPLMN network by touching the touch display screen, so that the target terminal switches to the target VPLMN network.
[0065] The VPLMN network determination method determines the network priority of each candidate VPLMN network according to the network performance parameters of the candidate VPLMN networks and the service demand corresponding to the target terminal, and then sends the network priority of each candidate VPLMN network to the target terminal, so that the target terminal selects a target VPLMN network from the candidate VPLMN networks according to the network priority of each candidate VPLMN network. According to the above content, it can be known that the network performance parameters of each candidate VPLMN network are obtained in advance in the process of determining the VPLMN network, and then the network performance of each candidate VPLMN network is represented according to the network performance parameters. In combination with the service demand corresponding to the target terminal, the network priority of each candidate VPLMN network is accurately obtained, so that the network priority of each candidate VPLMN network can meet the network performance and actual service demand of each candidate VPLMN network, ensuring the accuracy of the target terminal in selecting the target VPLMN network, ensuring the optimality of the target VPLMN network, and preventing the service experience of the target user from being affected.
[0066] In an embodiment, as shown in Figure 3 When it is necessary to determine the network priority of each candidate VPLMN network according to the network performance parameters of the candidate VPLMN networks and the service demand corresponding to the target terminal, the following content can be included:
[0067] S301, determining a service adaptation degree score between each candidate VPLMN network and the service demand.
[0068] It should be noted that the service adaptation degree score between each candidate VPLMN network and the service demand is determined by a pre-trained scoring model. Specifically, the network parameters of a certain candidate VPLMN network and the service demand are input into the scoring model, and the output result of the scoring model is obtained. The output result is the service adaptation degree score between the candidate VPLMN network and the service demand.
[0069] The network parameters can be network performance parameters corresponding to the candidate VPLMN network when performing different service demands.
[0070] Further, the training process of the scoring model includes: obtaining sample parameters of at least one sample network and sample demands corresponding to the corresponding sample network, determining sample scores corresponding to each sample parameter and each sample demand by manual labeling or the like, and training an initial model according to each sample parameter and each sample demand labeled with a sample score to obtain a trained scoring model.
[0071] S302, determine the performance parameter score of each candidate VPLMN network according to the network performance parameter of each candidate VPLMN network.
[0072] It should be noted that when it is necessary to determine the performance parameter score of each candidate VPLMN network according to the network performance parameter of each candidate VPLMN network, the performance parameter interval corresponding to different candidate parameter scores can be determined in advance, the candidate parameter score to which the network performance parameter belongs is determined according to the performance parameter interval to which the network performance parameter belongs, and the candidate parameter score to which the network performance parameter belongs is taken as the performance parameter score of the network performance parameter.
[0073] S303, determine the network priority of the corresponding candidate VPLMN network according to the performance parameter score of each candidate VPLMN network and the service adaptation degree score corresponding to the corresponding candidate VPLMN network.
[0074] It should be noted that when it is necessary to determine the network priority of the corresponding candidate VPLMN network according to the performance parameter score of each candidate VPLMN network and the service adaptation degree score corresponding to the corresponding candidate VPLMN network, the following content can be included: determining the parameter influence weight corresponding to the performance parameter score and the adaptation degree influence weight corresponding to the service adaptation degree score; performing weighted operation on the performance parameter score and the service adaptation degree score corresponding to each candidate VPLMN network according to the parameter influence weight and the adaptation degree influence weight to obtain the comprehensive score corresponding to each candidate VPLMN network respectively; and determining the network priority of each candidate VPLMN network according to the comprehensive score corresponding to each candidate VPLMN network respectively.
[0075] The parameter influence weight corresponding to the performance parameter score and the adaptation degree influence weight corresponding to the service adaptation degree score can be set or adjusted according to actual conditions and historical experience of operation and maintenance personnel, and the specific weight value of the parameter influence weight and the adaptation degree influence weight is not limited herein.
[0076] In an embodiment of the present application, when it is necessary to determine the comprehensive score corresponding to each candidate VPLMN network respectively, the following operations can be performed for each candidate VPLMN network: obtaining the performance parameter score and the service adaptation degree score corresponding to the candidate VPLMN network, performing weighted operation on the performance parameter score corresponding to the candidate VPLMN network through the parameter influence weight to obtain a first operation result, performing weighted operation on the service adaptation degree score corresponding to the candidate VPLMN network through the adaptation degree influence weight to obtain a second operation result, and taking the sum of the first operation result and the second operation result as the comprehensive score corresponding to the candidate VPLMN network respectively.
[0077] The VPLMN network determination method determines the network priority of each candidate VPLMN network by determining the service adaptation score and the performance parameter score of each candidate VPLMN network, and thus accurately obtains the network priority of each candidate VPLMN network, so that the network priority of each candidate VPLMN network can meet the network performance and actual service demand of each candidate VPLMN network.
[0078] In one embodiment, as shown in Figure 4 When it is necessary to determine the network priority of each candidate VPLMN network according to the network performance parameter of each candidate VPLMN network and the service demand corresponding to the target terminal, the following operations can be included:
[0079] S401, for each candidate VPLMN network, difference operation is performed on the network performance parameter of the candidate VPLMN network at the current time and the historical network performance parameter of the candidate VPLMN network corresponding to the previous historical time at the current time, to obtain a performance parameter variable.
[0080] S402, if the performance parameter variable is greater than a preset variable threshold, the network priority of each candidate VPLMN network is determined according to the network performance parameter of each candidate VPLMN network and the service demand corresponding to the target terminal.
[0081] The variable threshold can be set or adjusted according to actual conditions, and the value range of the variable threshold is not limited herein.
[0082] In one embodiment of the present application, before determining the network priority of each candidate VPLMN network, the following operations can be further included: verifying whether each VPLMN network meets any of the following trigger conditions, and if so, performing the operation of determining the network priority of each candidate VPLMN network according to the network performance parameter of each candidate VPLMN network and the service demand corresponding to the target terminal.
[0083] The trigger conditions can include but are not limited to: load rate trigger: the target cell load rate of a certain VPLMN network continuously exceeds 80% for 3 times; delay trigger: the end-to-end delay of a certain VPLMN network increases by 20% or more than the average value of the previous 5 minutes; packet loss rate trigger: the service packet loss rate of a certain VPLMN network exceeds 5% (the threshold value can be dynamically configured according to the service type).
[0084] The VPLMN network determination method determines the network priority of each candidate VPLMN network when the performance parameter variable is greater than the preset variable threshold, ensures that the network priority of each candidate VPLMN network can be determined in time in the case of network fluctuation, and facilitates the target terminal to select a network.
[0085] In one embodiment, as shown in Figure 5 The application can also include the following content:
[0086] S501, in the case that the target VPLMN network is not the candidate VPLMN network with the highest network priority, the target terminal is controlled to switch to the target VPLMN network, and a timer is started.
[0087] In one embodiment of the application, when the target terminal displays the network priority of each candidate VPLMN network, the target user can manually select a candidate VPLMN network with a network priority that is not the highest as the target VPLMN network; the target terminal reports the selection instruction (including the user identifier, the target VPLMN network, and the selection time) to the exemption management module of the HPLMN network through the user interaction module. After verifying the legality of the user selection, the exemption management module generates an exemption record, marks the exemption duration of the user, controls the target terminal to switch to the target VPLMN network, starts a timer, and suspends the SoR instruction update for the user.
[0088] S502, in the case that the counting duration of the timer reaches the preset exemption duration, the target terminal is controlled to switch from the target VPLMN network to the candidate VPLMN network with the highest network priority.
[0089] In one embodiment of the application, in the case that the counting duration of the timer reaches the preset exemption duration, the exemption management module automatically triggers a recovery instruction, the priority adjustment module generates the network priority of each candidate VPLMN network for the target user again, and the normal guidance logic is restored.
[0090] The exemption duration can be set or adjusted according to actual conditions and requirements, and the minimum value of the exemption duration is zero, and the maximum value is infinite.
[0091] The VPLMN network determination method, in the case that the target VPLMN network is not the candidate VPLMN network with the highest network priority, controls the target terminal to switch to the target VPLMN network and starts a timer, thereby realizing the autonomous network selection for the target user.
[0092] In an embodiment, as shown in Figure 6 When it is needed to send the network priority of each candidate VPLMN network to the target terminal, the following can be included:
[0093] S601, receiving network performance parameters of at least one candidate visited public land mobile network (VPLMN) network at a current time.
[0094] S602, determining a service adaptation degree score between each candidate VPLMN network and service demand.
[0095] S603, determining a performance parameter score of each candidate VPLMN network according to the network performance parameters of each candidate VPLMN network.
[0096] S604, determining a parameter influence weight corresponding to the performance parameter score and an adaptation degree influence weight corresponding to the service adaptation degree score.
[0097] S605, performing weighted operation on the performance parameter score and the service adaptation degree score corresponding to each candidate VPLMN network according to the parameter influence weight and the adaptation degree influence weight, to obtain a comprehensive score corresponding to each candidate VPLMN network respectively.

[0101] S609, in a case where a timing duration of the timer reaches a preset exemption duration, controlling the target terminal to switch from the target VPLMN network to the candidate VPLMN network with the highest network priority.
[0102] The VPLMN network determination method determines the network priority of each candidate VPLMN network according to the network performance parameters of the candidate VPLMN networks and the service demand corresponding to the target terminal, and then sends the network priority of each candidate VPLMN network to the target terminal, so that the target terminal selects a target VPLMN network from the candidate VPLMN networks according to the network priority of each candidate VPLMN network. According to the above content, it can be known that the network performance parameters of each candidate VPLMN network are obtained in advance in the process of determining the VPLMN network, and then the network performance of each candidate VPLMN network is represented according to the network performance parameters. In combination with the service demand corresponding to the target terminal, the network priority of each candidate VPLMN network is accurately obtained, so that the network priority of each candidate VPLMN network can meet the network performance and actual service demand of each candidate VPLMN network, ensuring the accuracy of the target terminal in selecting the target VPLMN network, ensuring the optimality of the target VPLMN network, and preventing the service experience of the target user from being affected.
