    Abstract: Systems, methods, and devices of the various embodiments enable evolved Multimedia Broadcast Multicast Service (“eMBMS”) network sharing, content sharing, and roaming. The various embodiments may enable Multimedia Broadcast Multicast Service (“MBMS”) service continuity across different public land mobile networks (“PLMNs”) by associating the same MBMS services providing identical content in different PLMNs with each other. In an embodiment, service discovery may be provisioned to a receiver device when or after the receiver device is attached to a PLMN. In an embodiment, content sharing across different PLMNs may be supported by a user service description indicating the different temporary mobile group identifiers (“TMGIs”) of the same service across different PLMNs. In another embodiment, content sharing across different PLMNs may be supported by a user service description indicating the same TMGI for the same service across different PLMNs. In an embodiment, MBMS keys may be shared across PLMNs.

    Abstract translation: 各种实施例的系统，方法和设备实现了演进的多媒体广播多播服务（“eMBMS”）网络共享，内容共享和漫游。 各种实施例可以通过将在不同PLMN中提供相同内容的相同MBMS服务彼此相关联来实现跨越不同公共陆地移动网络（“PLMN”）的多媒体广播多播服务（“MBMS”）服务连续性。 在实施例中，服务发现可以在接收机设备附接到PLMN时或之后被提供给接收机设备。 在一个实施例中，跨不同PLMN的内容共享可以由指示跨越不同PLMN的相同服务的不同临时移动组标识符（“TMGI”）的用户服务描述来支持。 在另一个实施例中，跨越不同PLMN的相同服务的用户服务描述可以支持跨不同PLMN的内容共享，指示相同服务的相同TMGI。 在一个实施例中，可以在PLMN之间共享MBMS密钥。

    Abstract: Methods, devices and systems for delivering broadcast data to client devices that do not support receiving broadcast transmissions. In an embodiment, a gateway device may be configured to receive a manifest file and related data segments via a first type of network protocol, such as LTE broadcasts. The manifest file may include data defining network addresses for one or more network resources, and may be modified to include a network address of a proxy server for the network resources. The proxy server may be configured to accept requests for data segments from client devices conforming to a second type of network protocol different from the first protocol, such as unicast. In an embodiment, the gateway device may transmit broadcast data for storage in a cache or alternatively a separate storage location accessible to the proxy server. The proxy server may be included in the gateway device or client devices.

    Abstract translation: 将广播数据传送到不支持接收广播传输的客户端设备的方法，设备和系统。 在一个实施例中，网关设备可以被配置为经由诸如LTE广播的第一类型的网络协议来接收清单文件和相关数据段。 清单文件可以包括定义一个或多个网络资源的网络地址的数据，并且可以被修改为包括网络资源的代理服务器的网络地址。 代理服务器可以被配置为接受来自符合不同于第一协议的第二类型的网络协议的客户端设备的数据段的请求，诸如单播。 在一个实施例中，网关设备可以发送用于存储在高速缓存中的广播数据，或者替代地代理服务器可访问的单独的存储位置。 代理服务器可以包括在网关设备或客户端设备中。

    Abstract: The systems, methods, and devices of the various embodiments enable a receiver device to adjust timing of requests for segments based on the actual times when the segments will be available on the receiver device. In various embodiments, a receiver device may be enabled to modify a segment availability timeline in which the availability times of the segments are adjusted to provide the actual times when segments will be available on the receiver device. In various embodiments, segment availability time adjustments may be made at a service layer of the receiver device. In various embodiments, segment availability time adjustments may be made by a client application on the receiver device. In the various embodiments, a network delay jitter estimate may be provided. In an embodiment, a network delay jitter estimate may be provided in a segment availability timeline.

    Abstract: A method, an apparatus, and a computer program product are provided in connection with facilitating hybrid unicast/broadcast service distribution. In one example, a communications device is equipped to provide a parity portion of titles in a channel of a service to a plurality of UEs at a first time, receive, from a UE at a second time, a request to access a title of the one or more titles, and provide an enablement item, to the requesting UE, which is a portion of the requested title that, when processed with the provided parity portion of the requested title, is sufficient to allow the requesting UE to decode and access to the requested title. In an aspect, the parity portion may be a parity portion of a fountain code encoded title, and the enablement item may be repair symbols of the fountain code encoded title.
