Detailed Description
In order to better understand the technical solution of the present invention, a method, a system and a network device for customizing a service according to the present invention are described in further detail below with reference to the accompanying drawings and embodiments.
Example 1:
as shown in fig. 1, the present embodiment provides a method for customizing a service, which is applied to a network device, and is particularly applicable to a network device of a 5G network, where the method includes:
and step 101, receiving a slice customization request sent by a user.
In this embodiment, the slice customization request includes a subscriber identity, e.g., the subscriber identity includes an IMSI (International Mobile Subscriber Identity ). The user browses and selects the sliced product through the login client software (such as app or website), or the login client software sends a slice customization request to the network device. For example, a user logs in to a game app, sends a slice customization request to a network device, the slice customization request including a user identification (IMSI), expects to subscribe to the network device to a network slice for a premium gaming service experience. It should be noted that, the user may log in the client software of multiple services at the same time, where the client software of multiple services sends a slice customization request to the network device, and the slice customization request includes the user identifier.
And 102, acquiring the service requirement of the user according to the slice customization request.
Specifically, the acquiring the service requirement of the user according to the slice customization request includes the following steps:
step 1021, obtaining the corresponding historical service data and behavior feature data of the user from the user service feature database according to the user identification of the slice customization request.
In this embodiment, the subscriber service feature database stores a mapping relationship among a subscriber identity (IMSI), subscriber history service data, subscriber behavior feature data, and the three. The user service feature database is located in a DPI (Deep Packet Inspection ) system, which is deployed in a mobile network, and obtains data through a preset configuration policy, for example, various data can be obtained from network element equipment, and the user service feature database is updated periodically. After the consumer is authenticated by the DPI system, the DPI system may provide data in a user traffic characteristics database to the consumer. In general, by analyzing the historical service data and behavior characteristic data of the user, the characteristics and preferences of the user are summarized, and the potential service demands of the user are deduced, so that the popularization of related services can be carried out by combining the historical data of the user when the services are developed.
Step 1022, obtaining the service requirement of the user according to the historical service data and the behavior characteristic data of the user, wherein the service requirement comprises the parameters of the sliced product capable of meeting the service requirement of the user.
In this embodiment, since the historical service data and the behavior feature data of the user are analyzed, the potential service requirement of the user can be deduced, and therefore, in this embodiment, a slicing requirement model is provided, in which the historical service data and the behavior feature data of the user are input, the slicing requirement model outputs parameters of slicing products required by the potential service requirement. For example, when a user is a game fan, and the user service feature database obtains the user identifier to perform a game service in a preset time period (for example, the preset time period is set to 30 days) or a fixed time period every day, the relevant data of the network flow is used, the relevant data such as the service type, the time data and the network flow data are input into the slicing requirement model, and the slicing requirement model outputs parameters of slicing products which can meet the requirements of the user when performing the game service, namely, obtains the specific game service requirement of the user, so that the service customization of the network slicing is performed according to the service requirement. For example, the business requirements include parameters of the slice product such as the required size of the slice, the slice type, the network rate, the slice validation time, the slice failure time, etc. In this embodiment, the historical service data and the behavior feature data of the user are automatically obtained according to the user identifier of the slice customization request, and the service requirement (i.e., the parameter requirement of the specific slice product) is automatically obtained according to the historical service data and the behavior feature data. The parameters of the required sliced products are automatically obtained through analyzing the historical service characteristics of the terminal, so that the degree of coincidence between the follow-up selected or customized sliced products and the service requirements of the user is higher, and the service experience of the user is improved.
Step 103, judging whether the existing sliced product can meet the service requirement of the user.
Specifically, judging whether the existing sliced product can meet the service requirement of the user includes two ways, one way is to judge whether the QoS (Quality of Service ) of the existing sliced product in the sliced mall can meet the service requirement of the user, for example, judging whether the existing sliced product can meet the game service requirement of the user in terms of time delay, packet loss rate, bit error rate, bandwidth, guaranteed rate and the like.
Another way is: matching the parameters of the existing sliced products with the parameters of the sliced products which can meet the business requirements of users; when the parameters of the existing sliced products are successfully matched with the parameters of the sliced products which can meet the service requirements of the users, judging that the existing sliced products can meet the service requirements of the users; when the parameter matching of the existing sliced product fails to meet the parameter matching of the sliced product meeting the service requirement, the judgment result is that the existing sliced product cannot meet the service requirement.
In this embodiment, the number of existing sliced products may be one or more, and the number of parameters of the sliced products may be one or more. The parameters of the existing sliced product and the parameters of the sliced product capable of meeting the service requirements of the user (namely, the parameters of the sliced product output by the sliced requirement model) are matched, for example, the parameters of the sliced product comprise the sliced type and the network rate, the sliced type of the existing sliced product is the same as the sliced type of the sliced product capable of meeting the service requirements, and when the network rate of the existing sliced product is higher than the network rate of the sliced product capable of meeting the service requirements, the judgment result is that the existing sliced product can meet the service requirements of the user. When the current sliced product does not meet the service requirement, step 104 is executed.
And 104, if the judgment result is negative, customizing a corresponding network slice according to the service requirement of the user.
In this embodiment, customizing the corresponding network slice according to the service requirement of the user includes: selecting a preset slicing template, and setting parameters of sliced products capable of meeting business requirements of users in the slicing template; setting a service level agreement (Service Level Agreement, SLA) required by slicing according to parameters of sliced products capable of meeting business requirements of users, wherein the SLA comprises a plurality of parameters such as user number, qoS (Quality ofService ), bandwidth and the like, and different SLAs are used for defining different communication service types; then converting the slice template into a template of the network service; selecting a proper slice according to a template of the network service, applying for slice resources, and managing the life cycle of the slice to generate a slice description file; and performing slice deployment according to the slice description file to generate a network slice capable of meeting the service requirements of the user and performing slice activation to provide network slice service for the user. It should be noted that, when the network device completes slice deployment, a response is returned to the client software (or the user terminal), and the returned response includes a success response of the user to subscribe to the slice, a slice type, a slice effective time, a slice dead time, and the like. In addition, when the user logs in the client software of a plurality of services at the same time and sends a slice customizing request, the service customizing method in the embodiment is adopted, and finally, the network slice automatically deployed and activated by the network equipment can meet a plurality of service demands of the user.
In the method for customizing the service provided in this embodiment, the service requirement of the user is obtained according to the slice customizing request sent by the user, then whether the existing slice product can meet the service requirement of the user is judged, if the judgment result is no, the corresponding network slice is customized according to the service requirement of the user. Therefore, the user can acquire the service requirement of the user when ordering the slicing service, and the existing slicing products can be automatically selected or parameters of the customized slicing can be determined according to the service requirement of the user. In addition, the historical service data and the behavior characteristic data of the user are automatically obtained according to the user identification of the slicing customization request, and the service requirement (namely the parameters of a specific slicing product) is automatically obtained according to the historical service data and the behavior characteristic data, so that the slicing product is customized, the degree of coincidence between the customized slicing product and the user service requirement is higher, and the network equipment can provide differentiated network slicing service for the user, so that the user service experience is improved. And for the network equipment, the network resources can be customized according to the business requirements of one or more users, so that the network resources are dynamically and reasonably allocated outside the differentiated business requirements of the users, and the management and use efficiency of the slices are optimized.
