Multicast broadcast multimedia service-assisted content distribution

摘要

Embodiments provide methods, systems, and apparatuses for multicast broadcast multimedia service (MBMS)-assisted content distribution in a wireless communication network. A proxy terminal may include an MBMS access client configured to receive and cache an MBMS transmission including media data and metadata. The proxy terminal may further include a hypertext transfer protocol (HTTP) server module configured to transmit at least a portion of the media data to a user equipment (UE) of the wireless communication network via an HTTP transmission. The media data and metadata may be in a dynamic adaptive streaming over HTTP (DASH) format. The proxy terminal may be included in an evolved Node B (eNB), the UE, or another UE of the wireless communication network.

主权项

1. A method to be performed by a proxy terminal, the method comprising:
activating multicast broadcast multimedia service (MBMS) with a broadcast multicast service center (BMSC); receiving media presentation description (MPD) metadata from the BMSC via user service discovery (USD) signaling, the MPD metadata associated with media data; receiving at least a portion of the media data associated with the MPD metadata from the BMSC via an MBMS transmission, the MBMS transmission being a broadcast transmission; caching the received media data and metadata; receiving a hypertext transfer protocol (HTTP) request from a HTTP access client hosted in a user equipment (UE) to receive at least a portion of the cached media data and metadata; and transmitting, in response to the HTTP request, the at least a portion of the cached media data and metadata to the UE via unicast HTTP signaling.
