[0020] Figure 1 1 is a schematic diagram of an environment 100 in which the methods, apparatuses, and systems described herein may be implemented, according to an embodiment. Figure 1 As shown, environment 100 may include user device 110, platform 120, and network 130. The devices of environment 100 may be interconnected via wired connections, wireless connections, or a combination of wired and wireless connections.

[0021] The user device 110 includes one or more devices that can receive, generate, store, process, and / or provide information related to the platform 120. For example, the user device 110 may include a computing device (e.g., a desktop computer, a laptop computer, a tablet computer, a handheld computer, a smart speaker, a server, etc.), a mobile phone (e.g., a smart phone, a wireless phone, etc.), a wearable device (e.g., smart glasses or a smart watch), or a similar device. In some embodiments, the user device 110 can receive information from the platform 120 and / or send information to the platform 120.

[0022] The platform 120 includes one or more devices as described elsewhere herein. In some embodiments, the platform 120 may include a cloud server or a cloud server group. In some embodiments, the platform 120 may be designed to be modular so that software components can be swapped in or out according to specific needs. In this way, the platform 120 can be easily and / or quickly reconfigured to have different uses.

[0023] In some embodiments, as shown, the platform 120 may be hosted in a cloud computing environment 122. It is worth noting that although the embodiments described herein describe the platform 120 as being hosted in a cloud computing environment 122, in some embodiments, the platform 120 is not cloud-based (i.e., may be implemented outside of a cloud computing environment) or may be partially cloud-based.

[0024] Cloud computing environment 122 includes an environment hosting platform 120. Cloud computing environment 122 can provide computing, software, data access, storage, and other services that do not require end users (e.g., user devices 110) to be aware of the physical location and configuration of the systems and / or devices hosting platform 120. As shown, cloud computing environment 122 can include a set of computing resources 124 (collectively, “Computing Resources 124” and individually, “Computing Resource 124”).

[0025] The computing resources 124 include one or more personal computers, workstation computers, server devices, or other types of computing and / or communication devices. In some embodiments, the computing resources 124 can host the platform 120. Cloud resources can include computing instances executed in the computing resources 124, storage devices provided in the computing resources 124, data transmission devices provided by the computing resources 124, etc. In some embodiments, the computing resources 124 can communicate with other computing resources 124 via wired connections, wireless connections, or a combination of wired and wireless connections.

[0026] Further Figure 1 As shown, the computing resources 124 include a set of cloud resources, such as one or more application programs ("APP") 124-1, one or more virtual machines ("VM") 124-2, virtualized storage ("VS") 124-3, one or more hypervisors ("HYP") 124-4, etc.

[0027] The applications 124-1 include one or more software applications that can be provided to or accessed by the user device 110 and / or the platform 120. The applications 124-1 do not require the software applications to be installed and executed on the user device 110. For example, the applications 124-1 may include software associated with the platform 120, and / or any other software that can be provided through the cloud computing environment 122. In some embodiments, one application 124-1 can send / receive information to or from one or more other applications 124-1 through the virtual machine 124-2.

[0028] Virtual machine 124-2 includes a software implementation of a machine (e.g., a computer) that executes programs, similar to a physical machine. Virtual machine 124-2 can be a system virtual machine or a process virtual machine, depending on the use and correspondence of virtual machine 124-2 to any real machine. System virtual machines can provide a complete system platform that supports the execution of a complete operating system ("OS"). Process virtual machines can execute a single program and can support a single process. In some embodiments, virtual machine 124-2 can execute on behalf of a user (e.g., user device 110) and can manage the infrastructure of cloud computing environment 122, such as data management, synchronization, or long-term data transfer.

[0029] Virtualized storage 124-3 includes one or more storage systems and / or one or more devices that use virtualization technology within the storage system or device of the computing resource 124. In some embodiments, within the context of the storage system, the types of virtualization may include block virtualization and file virtualization. Block virtualization may refer to the abstraction (or separation) of logical storage from physical storage so that the storage system can be accessed without considering the physical storage or heterogeneous structure. Separation may allow administrators of the storage system to flexibly manage the storage of end users. File virtualization may eliminate the dependency between data accessed at the file level and the location of the physical storage file. This may optimize the performance of storage usage, server consolidation, and / or non-disruptive file migration.

[0030] Hypervisor 124-4 may provide hardware virtualization technology that allows multiple operating systems (e.g., "guest operating systems") to execute simultaneously on a host computer such as computing resource 124. Hypervisor 124-4 may provide a virtual operating platform to the guest operating systems and may manage the execution of the guest operating systems. Multiple instances of various operating systems may share virtualized hardware resources.

[0031] The network 130 includes one or more wired and / or wireless networks. For example, the network 130 may include a cellular network (e.g., a fifth generation (5G) network, a long-term evolution (LTE) network, a third generation (3G) network, a code division multiple access (CDMA) network, etc.), a public land mobile network (PLMN), a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), a telephone network (e.g., a public switched telephone network (PSTN)), a private network, an ad hoc network, an intranet, the Internet, a fiber-based network, etc., and / or a combination of these or other types of networks.

[0036] Input components 250 include components that allow device 200 to receive information, such as through user input, such as a touch screen display, a keyboard, a keypad, a mouse, buttons, switches, and / or a microphone. Additionally or alternatively, input components 250 may include sensors for sensing information (e.g., global positioning system (GPS) components, accelerometers, gyroscopes, and / or actuators). Output components 260 include components that provide output information from device 200, such as a display, a speaker, and / or one or more light emitting diodes (LEDs).

[0037] The communication interface 270 includes a transceiver-like component (e.g., a transceiver and / or a separate receiver and transmitter) that enables the device 200 to communicate with other devices, for example, via a wired connection, a wireless connection, or a combination of wired and wireless connections. The communication interface 270 can allow the device 200 to receive information from another device and / or provide information to another device. For example, the communication interface 270 can include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a radio frequency (RF) interface, a universal serial bus (USB) interface, a Wi-Fi interface, a cellular network interface, etc.

[0038] Device 200 can perform one or more processes described herein. Device 200 can perform these processes in response to processor 220 executing software instructions stored by non-volatile computer-readable media (e.g., memory 230 and / or storage component 240).

[0041] The 5G Media Streaming (5GMS) system may be an assembly of application functions, application servers and interfaces from the 5G Media Streaming architecture that supports downlink media streaming services, or supports uplink media streaming services, or supports both. A 5GMS application provider may include a party that interacts with the functions of the 5GMS system and provides a 5GMS-aware application that interacts with the functions of the 5GMS system. A 5GMS-aware application may refer to an application in a user equipment (UE) provided by a 5GMS application provider, which contains the service logic of the 5GMS application service and interacts with other 5GMS clients and network functions via interfaces and application programming interfaces (APIs) defined in the 5GMS architecture. A 5GMS client may refer to a UE function, which may be either a 5GMS downlink (5GMSd) client or a 5GMS uplink (5GMS uplink, 5GMSu) client, or both.

[0042] 5GMSd Client may refer to a UE function that includes at least a 5G media streaming player and a Media Session Handler for downlink streaming, and can be accessed through a well-defined interface / API. 5GMSu Client may refer to the initiator of a 5GMSu service that can be accessed through a well-defined interface / API. 5GMSu Media Streamer may refer to a UE function that enables uplink streaming media content to the Application Server (AS) function of the 5GMS Application Provider, and interacts with a 5GMSu aware application for media capture and subsequent streaming, and a Media Session Handler for media session control.

[0043] Dynamic policy may refer to dynamic policy and charging control (PCC) rules for uplink or downlink application flows (Application Flow) during a media session. An Egest Session may refer to an uplink media streaming session (Uplink Media Streaming Session) from a 5GMS AS to a 5GMSu application provider. An Ingest Session may refer to a session for uploading media content to a 5GMSd AS. A Policy Template may refer to a collection of (semi-static) policy or control function (PCF) / network exposure function (NEF) API parameters that are specific to 5GMS application providers and the resulting PCC rules. A Policy Template ID may identify the desired policy template, which is used by the 5GMSd Application Function (AF) to select the appropriate PCF / NEF API for the 5G system so that the PCF can compile the desired PCC rules. A Media Player Entry may refer to a document or a pointer to a document that defines a Media Presentation (e.g., a Media Presentation Description (MPD) of DASH or a Uniform Resource Locator (URL) of a Video Clip File). A Media Streamer Entry may refer to a pointer (e.g., in the form of a URL) that defines an entry point for an uplink media streaming session. A Presentation Entry may refer to a document or a pointer to a document that defines an Application Presentation (e.g., an HTML5 document).

[0044] A Provisioning Session may refer to a data structure provided at an interface (M1d) by a 5GMSd Application Provider that configures 5GMSd features associated with a set of 5GMSd-aware applications. A 5GMSd Media Player may refer to a UE function that enables playback and rendering of a Media Presentation based on a Media Play Entry and exposes some basic controls, such as play, pause, search, stop, to 5GMSd-aware applications. Server Access Information may refer to a set of parameters and addresses (including 5GMSd AF and 5GMSd AS addresses) required to activate a receive streaming session. Service and Content Discovery may refer to functions and procedures provided by a 5GMSd Application Provider to a 5GMS-aware application that enables an end user to discover available streaming services and content offerings and select specific services or content items for access. Service Announcement may refer to a procedure executed between a 5GMS-aware application and a 5GMS application provider, so that the 5GMS-aware application can obtain 5GMS service access information directly or by referencing the information.

[0045] A third-party player may refer to a portion of an application that uses the API to exercise selected 5GMSd functions to play back media content. A third-party uplink streamer may refer to a portion of an application that uses the API to exercise selected 5GMSd functions to capture and stream media content.

[0046] Figure 3 300 is a diagram of a media architecture for media streaming according to an embodiment. A 5GMS application provider 301 may use 5GMS for uplink streaming services. In one or more examples, the streaming service may be a live video streaming session using a social media platform. The 5GMS application provider 301 may be implemented as a server. The 5GMS application provider 301 may provide a 5GMS-aware application 302 on a UE 303 to utilize a 5GMS client 304 and network functions using interfaces and APIs defined in 5GMS. A 5GMS application server (AS) 305 may be an AS dedicated to 5G media uplink streaming. The 5GMS client 304 may be an internal function of a UE 303 dedicated to 5G media streaming.

[0047] 5GMS Application Function (AF) 306 and 5GMS AS 305 may be data network (DN) 307 functions. 5GMS AF 306 may be implemented as a server. Functions in a trusted DN may be trusted by the operator network. Thus, the AF in a trusted DN may communicate directly with some or all 5G core functions. Functions in an external DN may communicate with the 5G core functions via a network exposure function (NEF) 308 using only link 320. NEF 308 facilitates secure access to public network services and capabilities of the 5G network.

[0048] The media architecture 300 can connect the UE 303 internal functions and related network functions for 5G media streaming. Therefore, the media architecture 300 can include multiple functions. For example, the 5GMS client 304 on the UE 303 can be the initiator of the 5GMS service that can be accessed through the interface / API. The 5GMS client 304 can include two sub-functions, a media session handler 309 and a media streamer 310. The media session handler 309 can communicate with the 5GMS AF 306 to establish, control and support the distribution of media sessions. The media session handler 309 can expose an API that can be used by the 5GMS-aware application 302. The media streamer 310 can communicate with the 5GMS AS 305 to stream media content and provide services to the 5GMS-aware application 302 for media capture and streaming, and provide services to the media session handler 309 for media session control. The 5GMS-aware application 302 can control the 5GMS client 304 by implementing external application or content service provider specific logic and enabling the establishment of media sessions. For example, the 5GMS AS 305 can host the 5G media functions and can be implemented as a content delivery network (CDN). The 5GMS application provider 301 can be an external application or content-specific media functions (e.g., media storage, consumption, transcoding, and redistribution) that streams media from the 5GMS-aware application 302 using 5GMS. The 5GMS AF 306 can provide various control functions to the media session handler 309 on the UE 303 and / or the 5GMS application provider 301. The 5GMS AF 306 can relay or initiate requests for different policy control functions (PCFs) 311 processing or interact with other network functions.

[0049] The media architecture 300 may include multiple different interfaces. For example, link 321 may involve M1, which may be a 5GMS provisioning API exposed by 5GMS AF 306 to supply the use of the media architecture 300 and obtain feedback. Link 322 may involve M2, which may be a 5GMS publishing API exposed by 5GMS AS 305 and used when selecting a 5GMS AS 305 in a trusted DN such as DN 307 to receive content for streaming services. Link 323 may involve M3, which may be an internal API for exchanging information for content hosted on 5GMS AS 305 within a trusted DN such as DN 307. Link 324 may involve M4, which may be a media streaming API exposed by 5GMS AS 305 to media streamer 310 for streaming media content. Link 325 may involve M5, which may be a media session handling API exposed by the 5GMS AF 305 to the media session handler for media session handling, control and assistance, which may also include appropriate security mechanisms (e.g., authorization and authentication). Link 326 may involve M6, which may be a UE 303 media session handling API exposed by the media session handler 309 to the 5GMS-aware application 302 to utilize 5GMS functions. Link 327 may involve M7, which may be a UE media streamer API exposed by the media streamer 310 to the 5GMS-aware application 302 and the media session handler 309 to utilize the media streamer 310. Link 328 may involve M8, which may be an application API for information exchange between the 5GMS-aware application 302 and the 5GMS application provider 301, such as providing service access information to the 5GMS-aware application 302. The UE 303 may also be implemented in a standalone manner such that interfaces M6 326 and M7 327 are not exposed.

[0050] Figure 3 The illustrated architecture defines how a client can stream content from a 5GMS application provider using a streaming format through the 5GMS architecture. The architecture provides an entry point for the format through service access information provided via M8 or M5. An entry point is a document or a pointer to a document that defines a streaming format. Recently, 3GPP has considered adding multiple entry points for the same service using one or more formats. In this case, the service operation information includes information about these entry points. The client selects a format and uses the corresponding entry point to start streaming content.

[0051] Embodiments of the present disclosure enable each media portal to implement a variety of service points. Since not all media portals can support the same service points, embodiments of the present disclosure provide a flexible solution that accommodates the following use cases: (1) one set of service points for all media portals; (2) one service point per media portal, with multiple media portals being provided; and (3) one set of service points per media portal, with multiple media portals being provided.

[0052] Table 1 provides example streaming access parameters as part of the service access information. Table 1: Streaming access parameters

[0053] The media entries are included in the hierarchical data structure. If the service operation point is outside the media entry, the service operation point may apply to all media entries. For example, the service operation point outside the media entry may be a global service operation point that applies to all media entries. In one or more examples, the service operation point outside the media entry may apply to a subset of the media entries. If the service operation point is included in a single media entry, the service operation point is applied to the media entry. For example, the service operation point within the media entry may be a local service operation point that applies only to the media entry.

[0054] Figure 4 An example data structure 400 defining service operation points and media entry points is illustrated. As shown in data structure 400, there are service operation points 00 to 01 that can be global and apply to all media entry points. n-1 In one or more examples, the service operation point 00 to 0 n-1 A subset of media entry points that may be applicable. In one or more examples, each media entry point may include an entry point document or a pointer to an entry point document. In one or more examples, each media entry point may include one or more service operation points that apply to that particular media entry point. For example, media entry 1 includes service operation points 10 to 11 that apply only to media entry 1. k1-1 In one or more examples, the media portal does not include any service operation points. In one or more examples, the data structure 400 may not include any service operation points outside of the media portal.

[0055] Figure 4 Each media entry shown may correspond to a different streaming format. The streaming format may vary based on the type of distribution of the media content and the type of device (e.g., TV, mobile phone, tablet) to which the media content is streamed.

[0056] Figure 5An example process 500 for signaling service operation points and media entry points in multiple formats is illustrated. The process 500 may be performed by the UE 303.

[0057] The process may begin at operation S502, where a data structure defining one or more service operation points and one or more media entry points is received. In one or more examples, the received data structure may correspond to data structure 400 ( Figure 4 ). In one or more examples, the data structure 400 may be received via a service announcement through an M8 or M5 interface. For example, the data structure 400 may be included in service announcement information provided by the 5GMS application provider 301 to the 5GMS-aware application 302.

[0058] The process proceeds to operation S504, where a media entry point is selected from one or more media entry points. For example, if UE 303 is a mobile phone, UE 303 may select a media entry point in data structure 400 that is most suitable for a mobile phone.

[0059] The process proceeds to operation S506, where a media distribution session is started based on the selected media entry point. For example, if UE 303 selects media entry 1 in operation S504, UE 303 can start a media distribution session using the entry point specified in the entry point document or a point pointing to the entry point document of media entry 1.
