DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
A user device may utilize a particular traffic category (e.g., particular quality of service (QoS), a particular traffic download data limit, a particular upload data limit, and/or the like) when accessing features of an application from a network. The user device may also utilize a particular network slice (referred to herein as a “slice”) of the network when accessing the features of the application from the network. However, the user device may not be authorized to utilize the particular traffic category and/or the particular network slice. Such network applications are abusing traffic categories and/or network slices since the user device utilizing such network applications fail to be authorized to utilize the particular traffic category and/or network slice. Thus, current mechanisms for handling traffic categories and/or network slices for network applications consume computing resources (e.g., processing resources, memory resources, communication resources, and/or the like), networking resources, and/or other resources associated with failing to provide traffic categories and/or network slices to user devices authorized to utilize the traffic categories and/or network slices, erroneously providing the traffic categories and/or network slices to user devices unauthorized to utilize the traffic categories and/or network slices, handling customer complaints from customers associated with the devices authorized to utilize the traffic categories and/or network slices, and/or the like.
Some implementations described herein provide a user device that prevents abuse of traffic categories and network slices by applications. For example, the user device receives a traffic category and/or slice usage policy, and may provide a request for an application. The user device may receive, based on the request, the application with a traffic category and/or slice usage requirement, and may install the application on the user device. The user device may subscribe, by a settings application of the user device, to traffic categories and/or slices, and may receive, by the settings application, approval to utilize the traffic categories and/or slices. The user device may provide, by the application and to an operating system of the user device, a connection request for a particular traffic category and/or slice, and may determine whether the application is approved for the particular traffic category and/or slice based on the approval to utilize the traffic categories and/or slices and based on the traffic category and/or slice usage policy. The user device may provide, by the operating system and to a modem of the user device, the connection request and traffic descriptors for the particular traffic category and/or slice based on the application being approved for the particular traffic category and/or slice, and may establish a protocol data unit session, for the application, utilizing the particular traffic category and/or slice.
In this way, the user device prevents abuse of traffic categories and network slices by applications. For example, the user device may prevent abuse of traffic categories and/or slices, by applications utilized by the user device, based on authorizing the applications to access the traffic categories and/or slices. An operating system provider of the user device may approve an application as being qualified to utilize traffic categories and/or slices, and a user of the user device may provide permission for the application to utilize the traffic categories and/or slices. The user device may subscribe to the traffic categories and/or slices, and may ensure that application data traffic utilizing the traffic categories and/or slices stay within a traffic profile set by a network. Thus, the user device may conserve computing resources, networking resources, and/or other resources that would otherwise have been consumed by failing to provide traffic categories and/or network slices to user devices authorized to utilize the traffic categories and/or network slices, erroneously providing the traffic categories and/or network slices to user devices unauthorized to utilize the traffic categories and/or network slices, handling customer complaints from customers associated with the user devices authorized to utilize the traffic categories and/or network slices, and/or the like.
FIGS. 1A-1E are diagrams of an example 100 associated with preventing abuse of traffic categories and network slices by applications. As shown in FIG. 1A, the example 100 may include a user device 102, a radio access network (RAN) 104, a core network 106, and an application server 108. Further details of the user device 102, the RAN 104, the core network 106, and the application server 108 are provided elsewhere herein.
As shown in FIG. 1A, and by reference number 110, the user device 102 may receive a traffic category and/or slice usage policy. For example, the core network 106 may define the traffic category and/or slice usage policy for the user device 102 based on a subscription of the user device 102 to services provided by the core network 106. The traffic category and/or slice usage policy may include a policy that defines one or more traffic categories and/or network slices that the user device 102 may utilize to access one or more services (e.g., applications provided by the application server 108), via the RAN 104 and the core network 106. In some implementations, the traffic category and/or slice usage policy may define a quality of service to be utilized by the user device 102 for application traffic, a download data limit of the user device 102 for application traffic, an upload data limit of the user device 102 for application traffic, and/or the like. In some implementations, the core network 106 may provide, via the RAN 104, the traffic category and/or slice usage policy to the user device 102, and the user device 102 may receive the traffic category and/or slice usage policy. Alternatively, the user device 102 may provide, to the core network 106, a request for traffic category and/or slice usage policy, and the core network 106 may provide the traffic category and/or slice usage policy to the user device 102 based on the request.
As further shown in FIG. 1A, and by reference number 112, the application server 108 may receive applications with traffic category and/or slice usage requirements. For example, a vendor of an operating system of the user device 102 may provide developer guidelines for using traffic categories and/or slices to developers of applications. The developer guidelines may include a mapping between traffic descriptors (e.g., a connection capabilities traffic descriptor) and the traffic categories and/or slices, and may include associated application programming interfaces (APIs) to be utilized by the developers. The developers may create, based on the developer guidelines, applications with traffic category and/or slice usage requirements of the applications. The developers may submit the applications to an application store that publishes applications for the user device 102. The application store support team may verify whether the applications satisfy the traffic category and/or slice usage requirements. If the applications satisfy the traffic category and/or slice usage requirements, the application store support team may approve the applications and may provide the applications to the application server 108. The application server 108 may receive the applications with traffic category and/or slice usage requirements from the application store support team, and may store the applications in a data structure (e.g., a database, a table, a list, and/or the like) associated with the application server 108.
As further shown in FIG. 1A, and by reference number 114, the user device 102 may provide a request for an application. For example, a user may utilize the user device 102 to browse the applications provided by the application server 108. The user may cause the user device 102 to generate a request for an application (e.g., of the applications), and to provide the request to the application server 108.
As further shown in FIG. 1A, and by reference number 116, the user device 102 may receive, based on the request, the application with a traffic category and/or slice usage requirement. For example, the application server 108 may receive the request for the application from the user device 102, and may provide (e.g., via a download) the application to the user device 102 based on the request for the application. The user device 102 may receive (e.g., download) the application from the application server 108, and may store the application in a data structure associated with the user device 102. The application may be associated with a traffic category and/or slice usage.
As shown in FIG. 1B, and by reference number 118, the user device 102 may install the application. For example, the user may cause the user device 102 to install the application with the traffic category and/or slice usage. In some implementations, the application server 108 and/or the application store may recommend to the user of the user device 102 the traffic categories and/or slices required for best performance of the application. In some implementations, after installing the application, the user device 102 may inform the user that the application requires access to particular traffic categories and/or slices for optimal performance, and may provide a link (e.g., a uniform resource locator (URL)) to subscribe to the particular traffic categories and/or slices.
As further shown in FIG. 1B, and by reference number 120, a settings application of the user device 102 may subscribe to traffic categories and/or slices. For example, the user device 102 may include a settings application that enables the user device 102 to interact with a portal provided by a provider of the core network 106, and to subscribe to traffic categories and/or slices desired by the user. In some implementations, the user device 102 may provide a link to the portal in a user interface of the user device 102 for user convenience. The user device 102 may provide, to the core network 106, a subscription request for the traffic categories and/or slices.
As further shown in FIG. 1B, and by reference number 122, the settings application of the user device 102 may receive approval to utilize the traffic categories and/or slices. For example, the core network 106 may receive, from the user device 102, the subscription request for the traffic categories and/or slices, and may determine whether the user device 102 is approved to utilize the traffic categories and/or slices based on the subscription request and a subscription plan associated with the user of the user device 102. If the core network 106 approves the utilization of the traffic categories and/or slices, the core network 106 may provide approval to utilize the traffic categories and/or slices to the user device 102, and the user device 102 may receive the approval to utilize the traffic categories and/or slices. The approval to utilize the traffic categories and/or slices may include appropriate UE route selection policy (URSP) rules for the user device 102 to utilize the traffic categories and/or slices. In some implementations, the user of the user device 102 may permit the application to use any or all of the traffic categories and/or slices, irrespective of whether the user device 102 has subscribed to the traffic categories and/or slices.
As further shown in FIG. 1B, and by reference number 124, the application of the user device 102 may provide, to an operating system of the user device 102, a connection request for a particular traffic category and/or slice. For example, the user may cause the user device 102 to execute the application (e.g., based on selection of the application from a user interface). When executed, the application may generate the connection request for the particular traffic category and/or slice (e.g., for provisions of the application to the user device 102). The application may provide, to the operating system, the connection request for the particular traffic category and/or slice. In some implementations, the connection request may include appropriate traffic descriptors associated with the particular traffic category and/or slice.
As further shown in FIG. 1B, and by reference number 126, the operating system of the user device 102 may determine that the application is approved for the particular traffic category and/or slice. For example, the operating system may receive the connection request and may determine whether the application is approved for the particular traffic category and/or slice. In some implementations, the operating system may determine whether the application is approved for the particular traffic category and/or slice based on whether the application store support team verified that the application satisfies the traffic category and/or slice usage requirements, and based on whether the user of the user device 102 permitted the application to use the particular traffic category and/or slice. In some implementations, the operating system may determine that the application is approved for the particular traffic category and/or slice based on the application store support team verifying the application, and based on the user of the user device 102 permitting the application to use the particular traffic category and/or slice.
As further shown in FIG. 1B, and by reference number 128, the operating system of the user device 102 may provide, to a modem of the user device 102, the connection request and traffic descriptors (e.g., the URSP rules) for the particular traffic category and/or slice based on the application being approved for the particular traffic category and/or slice. For example, if the operating system determines that the application is approved for the particular traffic category and/or slice, the operating system may provide, to the modem, the connection request and the traffic descriptors for the particular traffic category and/or slice. The modem may receive the connection request and the traffic descriptors for the particular traffic category and/or slice.
As shown in FIG. 1C, and by reference number 130, the modem of the user device 102 may establish or reuse a protocol data unit (PDU) session, for the application, utilizing the particular traffic category and/or slice. For example, based on the connection request, the modem may establish a new PDU session or reuse an existing PDU session between the user device 102 and the core network 106. The modem may utilize the traffic descriptors (e.g., the URSP rules) for the particular traffic category and/or slice for the PDU session so that the application may utilize the particular traffic category and/or slice.
As further shown in FIG. 1C, and by reference number 132, the modem of the user device 102 may notify the operating system that a connection is granted utilizing the particular traffic category and/or slice. For example, when the PDU session is established and the modem is communicating with the application server 108, via the core network 106, the modem may generate a notification indicating that the connection is granted utilizing the particular traffic category and/or slice. The modem may provide, to the operating system, the notification indicating that the connection is granted utilizing the particular traffic category and/or slice. The operating system may receive the notification indicating that the connection is granted utilizing the particular traffic category and/or slice.
As further shown in FIG. 1C, and by reference number 134, the operating system of the user device 102 may notify the application that the connection is granted utilizing the particular traffic category and/or slice. For example, when the operating system receives the notification indicating that the connection is granted utilizing the particular traffic category and/or slice, and the operating system may provide, to the application, the notification indicating that the connection is granted utilizing the particular traffic category and/or slice.
As further shown in FIG. 1C, and by reference number 136, the operating system of the user device 102 may enforce a usage policy of the particular traffic category and/or slice for the application. For example, the operating system may utilize the traffic category and/or slice usage policy, previously received from the core network 106, to enforce a usage policy for the particular traffic category and/or slice for the application. This may ensure that the application is utilizing a particular traffic category and/or slice that is approved by the core network 106 for the user device 102.
As shown in FIG. 1D, and by reference number 138, alternatively, the operating system of the user device 102 may determine that the application is not approved for the particular traffic category and/or slice. For example, the operating system may determine that the application is not approved for the particular traffic category and/or slice based on the application store support team not verifying that the application satisfies the traffic category and/or slice usage requirements, based on the user of the user device 102 not permitting the application to use the particular traffic category and/or slice, or based on the user device 102 not subscribing to the particular traffic category and/or slice. In such instances, the operating system may determine that the application is to utilize a default traffic category and/or slice.
As further shown in FIG. 1D, and by reference number 140, the operating system of the user device 102 may provide, to the modem, the connection request and traffic descriptors for a default traffic category and/or slice based on the application not being approved for the particular traffic category and/or slice. For example, if the operating system determines that the application is not approved for the particular traffic category and/or slice, the operating system may provide, to the modem, the connection request and the traffic descriptors for the default traffic category and/or slice. The modem may receive the connection request and the traffic descriptors for the default traffic category and/or slice.
As shown in FIG. 1E, and by reference number 142, the modem of the user device 102 may establish or reuse a PDU session, for the application, utilizing the default traffic category and/or slice. For example, based on the connection request, the modem may establish a new PDU session or reuse an existing PDU session between the user device 102 and the core network 106. The modem may utilize the traffic descriptors (e.g., the URSP rules) for the default traffic category and/or slice for the PDU session so that the application may utilize the default traffic category and/or slice.
As further shown in FIG. 1E, and by reference number 144, the modem of the user device 102 may notify the operating system that a connection is granted utilizing the default traffic category and/or slice. For example, when the PDU session is established and the modem is communicating with the application server 108, via the core network 106, the modem may generate a notification indicating that the connection is granted utilizing the default traffic category and/or slice. The modem may provide, to the operating system, the notification indicating that the connection is granted utilizing the default traffic category and/or slice. The operating system may receive the notification indicating that the connection is granted utilizing the default traffic category and/or slice.
As further shown in FIG. 1E, and by reference number 146, the operating system of the user device 102 may notify the application that the connection is granted utilizing the default traffic category and/or slice. For example, when the operating system receives the notification indicating that the connection is granted utilizing the default traffic category and/or slice, the operating system may provide, to the application, the notification indicating that the connection is granted utilizing the default traffic category and/or slice.
As further shown in FIG. 1E, and by reference number 148, the operating system of the user device 102 may enforce a usage policy of the default traffic category and/or slice for the application. For example, the operating system may utilize the traffic category and/or slice usage policy, previously received from the core network 106, to enforce a usage policy for the default traffic category and/or slice for the application. This may ensure that the application is utilizing a default traffic category and/or slice that is approved by the core network 106 for the user device 102.
In this way, the user device 102 prevents abuse of traffic categories and network slices by applications. For example, the user device 102 may prevent abuse of traffic categories and/or slices, by applications utilized by the user device 102, based authorizing the applications to access the traffic categories and/or slices. An operating system provider of the user device 102 may approve an application as being qualified to utilize traffic categories and/or slices, and a user of the user device 102 may provide permission for the application to utilize the traffic categories and/or slices. The user device 102 may subscribe to the traffic categories and/or slices, and may ensure that application data traffic utilizing the traffic categories and/or slices satisfies a traffic profile set by a network. Thus, the user device 102 may conserve computing resources, networking resources, and/or other resources that would otherwise have been consumed by failing to provide traffic categories and/or network slices to user devices 102 authorized to utilize the traffic categories and/or network slices, erroneously providing the traffic categories and/or network slices to user devices 102 unauthorized to utilize the traffic categories and/or network slices, handling customer complaints from customers associated with the user devices 102 authorized to utilize the traffic categories and/or network slices, and/or the like.

The RAN 104 may transfer traffic between the user device 102 (e.g., using a cellular RAT), one or more base stations (e.g., using a wireless interface or a backhaul interface, such as a wired backhaul interface), and/or the core network 106. The RAN 104 may provide one or more cells that cover geographic areas.
In some implementations, the RAN 104 may perform scheduling and/or resource management for the user device 102 covered by the RAN 104 (e.g., the user device 102 covered by a cell provided by the RAN 104).

The network controller may communicate with the RAN 104 via a wireless or wireline backhaul. In some implementations, the RAN 104 may include a network controller, a self-organizing network (SON) module or component, or a similar module or component. In other words, the RAN 104 may perform network control, scheduling, and/or network management functions (e.g., for uplink, downlink, and/or sidelink communications of the user device 102 covered by the RAN 104).

The functional elements may be communicatively connected via a message bus 245. Each of the functional elements shown in FIG. 3 is implemented on one or more devices associated with a wireless telecommunications system. In some implementations, one or more of the functional elements may be implemented on physical devices, such as an access point, a base station, and/or a gateway. In some implementations, one or more of the functional elements may be implemented on a computing device of a cloud computing environment.

The memory 330 may include internal memory (e.g., RAM, ROM, or a hard disk drive) and/or removable memory (e.g., removable via a universal serial bus connection). The memory 330 may be a non-transitory computer-readable medium. Memory 330 stores information, instructions, and/or software (e.g., one or more software applications) related to the operation of the device 300.
