[0017] Detailed embodiments of the claimed structures and methods are disclosed herein; however, it will be understood that the disclosed embodiments are merely illustrative of the claimed structures and methods, which may be implemented in various forms. However, these structures and methods may be implemented in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete and fully convey the scope to those skilled in the art. In the description, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments.

[0018] Embodiments generally relate to the field of data processing, and more specifically to 5G networks. The exemplary embodiments described below provide a system, method, and computer program for, among other things, preparing content for 5G networks. Accordingly, some embodiments can improve the field of computing by allowing the definition of reverse address mapping for content preparation processes for 5G networks.

[0019] As previously described, 3GPP TS26.512 defines the concept of content preparation templates to set up the processing of media streams before hosting the streamed content. 3GPP TS26.512 also defines content hosting configurations for content distribution. The current 5G media streaming architecture defined in 3GPP TS26.501 only defines a common architecture for uplink and downlink media streaming. 3GPP TS26.512 defines the concept of content preparation templates (CPTs) to prepare received content for downlink streaming. However, 3GPP TS26.512 does not define a process for content loss with content preparation. Therefore, it may be advantageous to use reverse address mapping in the content preparation process.

[0020] The 5G Media Streaming (5GMS) system may be a collection of application functions, application servers, and interfaces from the 5G Media Streaming architecture, supporting downlink media streaming services, or uplink media streaming services, or downlink media streaming services and uplink media streaming services. A 5GMS application provider may include a party that interacts with the functions of the 5GMS system and provides 5GMS-aware applications that interact 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 through interfaces and application programming interfaces (APIs) defined in the 5GMS architecture. A 5GMS client may refer to a UE function that is a 5GMS downlink (5GMSd) client, or a 5GMS uplink (5GMSu) client, or a 5GMSd client and a 5GMSu client.

[0021] 5GMSd Client may refer to a UE function that includes at least a 5G Media Streamer and a Media Session Handler for downlink streaming and is accessible via a well-defined interface / API. 5GMSu Client may refer to an initiator of a 5GMSu service and is accessible via a well-defined interface / API. 5GMSu Media Streamer may refer to a UE function that enables uplink streaming of streaming media content to an Application Server (AS) function of a 5GMS Application Provider and interacts with 5GMSu-aware applications for media capture and subsequent streaming and a Media Session Handler for media session control.

[0022] Dynamic policy may refer to dynamic policy and charging control (PCC) rules for uplink or downlink application flows during a media session. An egest session may refer to an uplink media streaming session from a 5GMS AS to a 5GMSu application provider. An ingest session may refer to a session in which media content is uploaded to a 5GMSd AS. A policy template may refer to a set of (semi-static) policy or control function (PCF) / network exposure function (NEF) API parameters specific to a 5GMS application provider, 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 that defines a media presentation or a pointer to a document (e.g., a media presentation description (MPD) for DASH or a uniform resource locator (URL) pointing to a video clip file). A media streamer entry may refer to a pointer (eg, 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, such as an HTML5 document.

[0023] A provisioned session may refer to a data structure provided by a 5GMSd application provider at an interface (M1d) that configures 5GMSd features associated with a set of 5GMSd-aware applications. A 5GMSd media player may refer to a UE function that is capable of playing and rendering media representations based on media playback entries and exposing some basic controls such as play, pause, seek, stop to 5GMSd-aware applications. Server access information may refer to a set of parameters and addresses (including 5GMSd AF address and 5GMSd AS address) required to activate the reception of a streaming session. Service and content discovery may refer to functions and procedures provided by a 5GMSd application provider to 5GMS-aware applications that enable end users to discover available streaming services and content products and select specific services or content items for access. Service announcement may refer to a procedure conducted between a 5GMS-aware application and a 5GMS application provider that enables the 5GMS-aware application to obtain 5GMS service access information directly or in the form of a reference to the 5GMS service access information.

[0024] A third-party player may refer to a portion of an application that uses the API to perform selected 5G MSd functions to play media content. A third-party uplink streamer may refer to a portion of an application that uses the API to perform selected 5G MSd functions to capture and stream media content.

[0025] In this document, various aspects are described with reference to flowcharts and / or block diagrams of methods, devices (systems), and computer-readable media according to various embodiments. It should be understood that each block of the flowcharts and / or block diagrams, and combinations of blocks in the flowcharts and / or block diagrams, can be implemented by computer-readable program instructions.

[0026] Now refer to Figure 1 , shows a functional block diagram of a networked computer environment, in which a content preparation system 100 (hereinafter referred to as "system") for content preparation for 5G networks is shown. It should be understood that Figure 1 This is merely an illustration of one implementation and does not imply any limitations with respect to the environments in which different embodiments may be implemented. Many modifications to the depicted environments may be made based on design and implementation requirements.

[0027] System 100 may include a computer 102 and a server computer 114. Computer 102 may communicate with server computer 114 via a communication network 110 (hereinafter referred to as "network"). Computer 102 may include a processor 104 and a software program 108 stored on a data storage device 106, and the computer may interface with a user and communicate with server computer 114. Figure 4 As discussed, computer 102 may include internal components 800A and external components 900A, respectively, and server computer 114 may include internal components 800B and external components 900B, respectively. For example, computer 102 may be a mobile device, a phone, a personal digital assistant, a netbook, a laptop, a tablet computer, a desktop computer, or any other type of computing device capable of running programs, accessing a network, and accessing a database.

[0028] The server computer 114 may also operate in a cloud computing service model such as Software as a Service (SaaS), Platform as a Service (PaaS), or Infrastructure as a Service (IaaS), as described below with respect to Figure 5 and Figure 6 The server computer 114 may also be located in a cloud computing deployment model, such as a private cloud, a community cloud, a public cloud, or a hybrid cloud.

[0029] The server computer 114 can be used for content preparation of the 5G network and can run a content preparation program 116 (hereinafter referred to as "program") that can interact with the database 112. Figure 3The content preparation program method is explained in more detail. In one embodiment, computer 102 may operate as an input device including a user interface, while program 116 may primarily run on server computer 114. In an alternative embodiment, program 116 may primarily run on one or more computers 102, while server computer 114 may be used to process and store data used by program 116. It should be noted that program 116 may be a stand-alone program or may be integrated into a larger content preparation program.

[0030] However, it should be noted that in some instances, processing of program 116 may be shared in any ratio between computer 102 and server computer 114. In another embodiment, program 116 may operate on more than one computer, server computer, or some combination of computers and server computers, such as, for example, multiple computers 102 communicating with a single server computer 114 via network 110. In another embodiment, program 116 may operate on multiple server computers 114 communicating with multiple client computers via network 110. Alternatively, the program may operate on a network server that communicates with both the server and multiple client computers via the network.

[0031] The network 110 may include a wired connection, a wireless connection, a fiber optic connection, or some combination thereof. In general, the network 110 may be any combination of connections and protocols that will support communication between the computer 102 and the server computer 114. The network 110 may include various types of networks, such as a local area network (LAN), a wide area network (WAN) such as the Internet, a telecommunications network such as the public switched telephone network (PSTN), a wireless network, a public switched network, a satellite network, 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 metropolitan area network (MAN), a private network, an ad hoc network, an intranet, a fiber-optic-based network, etc., and / or combinations of these or other types of networks.

[0032] Figure 1 The number and arrangement of devices and networks shown are provided as examples. In practice, there may be more than Figure 1 The devices and / or networks shown may be more devices and / or networks, fewer devices and / or networks, different devices and / or networks, or devices and / or networks that are different from the devices and / or networks shown. Figure 1 The devices and / or networks shown may be arranged differently. Figure 1 Two or more of the devices shown may be implemented in a single device, or Figure 1The single device shown may be implemented as multiple distributed devices. Additionally or alternatively, one set of devices (eg, one or more devices) of system 100 may perform one or more functions described as being performed by another set of devices of system 100.

[0033] Now refer to Figure 2A , depicting Figure 200A of content preparation prior to downlink streaming. In the collaborative use case, the 5GMSd application provider requests content preparation for its stream and then distributes it. In the use case of downloading without content preparation, the content is provided by the application provider through M2d. M2d refers to the 5GMSd ingest API. The 5GMSd ingest API is an optional external API exposed by the 5GMSd AS and is used when a 5GMSd AS in a trusted data network is selected to host the content for the streaming service. One option is to obtain the content from the application provider using the HTTP pull-based ingest protocol defined in 3GPP TS26.512. If the content is ready for distribution, it is distributed based on the content hosting configuration template (HCT) set by the application provider. In this use case, when content is requested by the client, if the content is available on the 5GMSd AS, the content is transmitted to the client. However, if the content is not available or lost, the corresponding original content is requested from the application provider. 3GPP TS 26.512 defines a simple rewriting process for a client to construct the address of the original content based on the requested content address. This rewriting process generates a URL address.

[0034] In the use case of download with content preparation, the content is provided by the application provider via M2d. One option is to pull the content from the application provider using an ingestion protocol based on HTTP pull. The content is then prepared for distribution as defined in the Content Preparation Template (CPT) set by the application provider and finally distributed based on the Content Hosting Configuration Template (HCT) set by the application provider. In this use case, when content is requested by the client, if the content is available on the 5GMSdAS, the content is transmitted to the client. However, if the content is not available or is lost, the corresponding original content required for content preparation must be requested from the application provider. If there is a simple mapping rule between the requested content and the original content, the path rewriting rules of 3GPP TS26.512 can be used. However, if the content creation is more complex, for example, the creation of the content uses multiple original contents, then path rewriting may not be able to solve the generation of the required multiple fragments of the original content.

[0035] Now refer to Figure 2B, depicting Figure 200B which uses a content preparation map to address missing content. Using a reverse address map as part of the content preparation template can provide a more comprehensive solution for computing the required content pull in the event that a client requests missing content. In this approach, content is requested by the client. A content selector requests the content from the cache and / or memory. If the content is available, the content is transferred to the client via the M4d interface. However, if the content is missing, the content selector requests a content preparation process (CPP). The CPP has two parts: a content generation process (CGP), which processes the input content and provides output to the cache / memory; and a reverse address map (RAM), which maps the client URL request to one or more URLs and requests them via M2d.

[0036] Now refer to Figure 2C , depicting a call flow diagram 200C when content is not available or missing from memory. The call flow can define a process when content requested by a client is missing from cache and / or memory. In this design, reverse address mapping is part of the content preparation process and can therefore be defined by the content preparation template in its format. Since content preparation templates can have different formats, reverse address mapping is also defined in the corresponding format. If a content preparation template defines multiple inputs, then using a content preparation template with multiple inputs can allow address mapping to be performed for each input.

[0037] If content preparation templates are cascaded, using the cascaded content preparation templates allows address mapping to be performed in a set of serial operations. In this case, if content preparation processes 1, 2, ..., N are cascaded one after another, reverse address mapping can be performed in a cascaded manner by applying the reverse address mapping of content preparation templates N, N-1, ..., 1 in that order.

[0038] When using a workflow of content preparation templates in a more complex setting, when some of the multiple content preparation templates (CPTs) have multiple inputs, multiple CPTs can be used to build the workflow. In this case, address mapping can be performed by backpropagation of the reverse address mapping, which starts from the last CPT and calculates backwards in the order of the input addresses.

[0039] Now refer to Figure 3 , depicts an operational flow diagram illustrating the steps of a method 300 performed by a program for content preparation in a 5G network.

[0040] At 302, method 300 can include identifying a reverse address mapping process associated with a content preparation process.

[0041] At 304, method 300 may include calculating a media content address based on the identified reverse address mapping process.

[0042] At 306 , method 300 may include generating a workflow of a content preparation process based on the calculated media content addresses.

[0043] I understand. Figure 3 This is merely an illustration of one implementation and does not imply any limitation on how different embodiments may be implemented. Many modifications may be made to the depicted environments based on design and implementation requirements.

[0044] Figure 4 According to the illustrative embodiment Figure 1 A block diagram 400 of the internal and external components of a computer is depicted. It should be understood that Figure 4 This is merely an illustration of one implementation and does not imply any limitations with respect to the environments in which different embodiments may be implemented. Many modifications to the depicted environments may be made based on design and implementation requirements.

[0045] Computer 102 ( Figure 1 ) and server computer 114 ( Figure 1 ) may include Figure 4 Respective groups of internal components 800A, 800B and external components 900A, 900B are shown, with each group of internal components 800 including one or more processors 820 on one or more buses 826, one or more computer-readable RAMs 822 and one or more computer-readable ROMs 824, one or more operating systems 828, and one or more computer-readable tangible storage devices 830.

[0051] It should be understood in advance that although the present disclosure includes a detailed description of cloud computing, the implementation of the teachings described herein is not limited to a cloud computing environment. Instead, some embodiments can be implemented in conjunction with any other type of computing environment now known or later developed.

[0052] Cloud computing is a service delivery model that enables convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage devices, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with the service provider. The cloud model can include at least five characteristics, at least three service models, and at least four deployment models.

[0053] Features are as follows:

[0054] On-demand self-service: Cloud consumers can automatically and unilaterally provision computing capabilities, such as server time and network storage, as needed without requiring manual interaction with the service provider.

[0055] Broad network access: Capabilities are available over the network and accessed through standard mechanisms that facilitate the use of heterogeneous thin or thick client platforms (such as mobile phones, laptops and PDAs).

[0056] Resource pooling: A provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, where different physical and virtual resources are dynamically allocated and reallocated based on demand. This is location-independent in the sense that consumers typically do not control or know the precise location of the provided resources, but are able to specify the location at a higher level of abstraction (e.g., country, state, or data center).

[0057] Rapid elasticity: Capacity can be provisioned quickly and elastically, in some cases automatically, to quickly scale out and quickly released to quickly scale in. To the consumer, the capacity available for provisioning often appears unlimited and can be purchased at any time and in any quantity.

[0058] Measured services: Cloud systems automatically control and optimize resource usage by leveraging metering capabilities at a level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency to both providers and consumers of the services being used.

[0059] The service model is as follows:

[0060] Software as a Service (SaaS): The capabilities provided to consumers are to use the provider's applications running on cloud infrastructure. The applications are accessible from a variety of client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure, including the network, servers, operating systems, storage, or even individual application capabilities, except perhaps for limited user-specific application configuration settings.

[0061] Platform as a Service (PaaS): Capabilities provided to consumers are deployed on applications created or acquired by the cloud infrastructure consumer using programming languages ​​and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure, including networks, servers, operating systems, or storage, but does control the deployed applications and the configuration of the hosting environment.

[0062] Infrastructure as a Service (IaaS): The capabilities provided to consumers include processing, storage, networking, and other basic computing resources on which consumers can deploy and run arbitrary software, including operating systems and applications. Consumers do not manage or control the underlying cloud infrastructure, but do have control over the operating system, storage, deployed applications, and possibly limited control over select networking components (e.g., host firewalls).

[0063] The deployment model is as follows:

[0064] Private cloud: Cloud infrastructure is operated solely for an organization. The cloud infrastructure can be managed by the organization or a third party and can exist on-premises or off-premises.

[0065] Community cloud: Cloud infrastructure is shared by several organizations and supports a specific community with shared concerns (such as mission, security requirements, policy, and compliance considerations). The cloud infrastructure can be managed by the organization or a third party and can exist as an internal or external deployment.

[0066] Public cloud: Cloud infrastructure available to the general public or large industrial groups and owned by an organization that sells cloud services.

[0067] Hybrid cloud: A cloud infrastructure consisting of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technologies that enable data and application portability (e.g., cloud bursting for load balancing between clouds).

[0068] Cloud computing environments are service-oriented, focusing on statelessness, low coupling, modularity, and semantic interoperability. The core of cloud computing is the infrastructure consisting of a network of interconnected nodes.

[0069] refer to Figure 5 , depicts an illustrative cloud computing environment 500. As shown, the cloud computing environment 500 includes one or more cloud computing nodes 10, and local computing devices used by cloud consumers can communicate with the cloud computing nodes 10, such as personal digital assistants (PDAs) or cellular phones 54A, desktop computers 54B, laptop computers 54C and / or automobile computer systems 54N. The cloud computing nodes 10 are communicative with each other. The cloud computing nodes 10 can be physically or virtually grouped (not shown) into one or more networks, such as the private clouds, community clouds, public clouds, or hybrid clouds described above, or a combination thereof. This allows the cloud computing environment 500 to provide infrastructure, platforms, and / or software as services without the cloud consumer needing to maintain resources on local computing devices. It should be understood that Figure 5 The types of computing devices 54A-N shown are intended to be illustrative only, and cloud computing node 10 and cloud computing environment 500 may communicate with any type of computerized device over any type of network and / or network-addressable connection (e.g., using a web browser).

[0070] refer to Figure 6 , showing a cloud computing environment 500 ( Figure 5 ) provides a set of functional abstraction layers 600. It should be understood in advance that Figure 6 The components, layers, and functions shown are intended to be illustrative only, and the embodiments are not limited thereto. As depicted, the following layers and corresponding functions are provided:

[0071] The hardware and software layer 60 includes hardware and software components. Examples of hardware components include: host 61; server 62 based on RISC (Reduced Instruction Set Computer) architecture; server 63; blade server 64; storage device 65; and network and networking components 66. In some embodiments, software components include network application server software 67 and database software 68.

[0072] Virtualization layer 70 provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers 71 ; virtual storage 72 ; virtual networks 73 , including virtual private networks; virtual applications and operating systems 74 ; and virtual clients 75 .

[0073] In one example, the management layer 80 may provide the functionality described below. Resource provisioning 81 provides dynamic acquisition of computing and other resources for performing tasks within a cloud computing environment.
