and sending the service description information to the modem through the data routing channel.
The network slicing service determining method receives a network slicing service request sent by an application program; the network slice service request carries identity information of an application program; matching the identity information with subscription information stored in a database, and determining service description information corresponding to the application program in the target subscription information; and sending the service description information to the modem so that the modem determines the network slice service corresponding to the application program according to a preset user equipment routing strategy and the service description information. Therefore, the method can acquire and match the slice service description (TD) information at the terminal side, and can greatly reduce the modification amount and the maintenance cost of the application program.
The following describes the above with a specific scenario embodiment.
In the embodiment, the terminal acquires and matches the slice service description (TD) information by presetting the network slice request management module in the terminal and combining the intelligent terminal capability configuration platform, so that the modification amount and the maintenance cost of the application program can be greatly reduced. The slice request management module and the terminal capability configuration platform are both provided and controlled by an operator, so that the authenticity of TD information can be guaranteed to a certain extent, and the risk of falsely using slice resources is reduced.
In the embodiment, a network slicing request management module is added at a terminal side and is matched with an intelligent terminal capability configuration platform, so that when an application program initiates a slicing service request, the terminal acquires and matches slicing service description (TD) information. The system architecture is shown in fig. 2, wherein the introduced main modules include a network slice request management module and an intelligent terminal capability configuration platform.
A network slice request management module: the module is preset in the terminal and is developed by a terminal manufacturer, provided by a network operator or developed by a third party. The main functions are as follows: (1) storing and updating service description (TD) information of an application subscribed to a network slicing service; (2) matching TD information corresponding to the application program when the terminal requests to establish the slice; (3) and initiating the establishment of a slice dedicated data channel and transmitting the TD information to the Modem.
The intelligent terminal capability configuration platform comprises: the platform is governed by the operator. The main function of the system is to input the signing information (package name, signature and service description information TD of application) of all application programs of the network slicing service, and transmit the signing information to the network slicing request management module of the terminal.
As shown in fig. 2, the flow of the network slicing service determining method mainly includes (i) to (ii).
Firstly, recording the contract signing information of the APP slicing service. And inputting the APP section service subscription information in the APP section subscription information database into an intelligent terminal capacity configuration platform.
And step two, configuring subscription information. And the intelligent terminal capability configuration platform configures the subscription information to the network slicing request management module.
Initiating a slicing service request by the APP and calling the slicing service management module.
And matching the TD information corresponding to the request slice APP.
Initiating the establishment of special data bearer of the slice, and transmitting TD information to the Modem.
Sixthly, matching the TD information transmitted by the APP with the TD in the URSP rule, and selecting a corresponding slice identifier to send to the network.
As shown in fig. 3, step 1: and an APP section signing database is input into a terminal capability configuration platform. The application programs subscribe the slicing service of the operator, and the operator inputs the subscription information (the package name, the signature and the service description information TD) of the application into the intelligent terminal capability configuration platform. The intelligent terminal capability configuration platform maintains a slicing service subscription database of all application manufacturers, and the database needs to be updated in real time along with the change of the slicing subscription condition of the application program (the application using the slices is added or deleted, and the subscription information is changed).
Step 2 a: and requesting subscription information data.
And step 2 b: and the capability configuration platform issues the subscription information data.
A network slice request management module preset in the terminal initiates a request for acquiring slice subscription information data (triggering time comprises starting up, inserting an SIM card, receiving a push message informing slice subscription information change by the terminal, overtime of a timer and the like), and the capability configuration platform sends the slice subscription information data to the network slice request management module of the terminal.
And step 3: the APP calls a network slice request management module. The application program initiates a slicing service request and calls a network slicing request management module. The application program interface does not need to carry TD information in the step.
And 4, step 4: and matching the TD information corresponding to the request slice APP. And the network slicing request management module matches the package name and the signature of the application program with the subscription information stored in the database, and retrieves the service description information TD corresponding to the application program. The TD information is remotely configured by an intelligent terminal capability configuration platform of an operator, so that the TD information can be prevented from being falsely used by illegal application to a certain extent.
Step 5 a: and transmitting TD information corresponding to the APP.
And step 5 b: TD information is transferred.
The network slice request management module initiates special data bearer establishment for the application program of the signed slice by calling the operating system interface, establishes a slice-specific data routing channel so as to route the application program data to the slice-specific channel and transmits the TD information to Modom.
Step 6: and (5) carrying out URSP regulation matching. The Modem receives the service description information TD transmitted by the operating system, matches with TD information in a URSP rule configured for the terminal by a core network, triggers PDU Session establishment, and maps the application onto a corresponding slice.
At present, an application program does not carry service description information TD, and if an application manufacturer modifies an application program interface to increase TD information, the development cost and the maintenance cost which need to be invested are higher. In the embodiment, the acquisition and matching of the TD information are realized by the slice request management module preset in the terminal, and the modification amount of an application manufacturer is greatly reduced.
The intelligent terminal capability configuration platform uniformly configures the TD information of the application program for the terminal, so that illegal application can be prevented from falsely using the TD information of legal application to a certain extent, and higher slicing service safety guarantee is provided.
