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:
Embodiments enable HTTP servers to pass incomplete and/or corrupted files in response to file requests from clients. In the various embodiments, HTTP servers may be enabled to generate status codes identifying that an incomplete version of a file is being returned in response to a file request. In an embodiment, an HTTP server may be enabled to determine the ability of a client to handle incomplete versions of files.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an eMBMS middleware. The apparatus receives a request to activate reception of an eMBMS service. The apparatus receives a request for a segment associated with the eMBMS service. The apparatus determines whether the segment of the eMBMS service is available at the eMBMS middleware. The apparatus fetches the segment from the unicast server if the segment is not available at the eMBMS middleware.
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:
The systems, methods, and devices of the various embodiments enable elastic response times to file requests by a server. In this manner, the server may account for unpredictable delay in object/segment availability and reduce the frequency that error messages (e.g., 404 error messages) are returned in response to file requests when file unavailability is temporary and due to network delays.
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.
