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 employed by a proxy terminal, the method comprising:
activating, by the proxy terminal, multicast broadcast multimedia service (MBMS) with a broadcast multicast service center (BMSC); receiving media presentation description (MPD) information from the BMSC via user service discovery (USD) signaling, the MPD information associated with dynamic adaptive streaming over hypertext transfer protocol (DASH) media segments; receiving at least some of the DASH media segments associated with the MPD information from the BMSC via MBMS broadcast transmission; caching the received DASH media segments and MPD information; receiving a hypertext transfer protocol (HTTP) request from a DASH client hosted in a user equipment (UE) to request a first DASH media segment of the cached DASH media segments; and sending, in response to the HTTP request, the first DASH media segment to the DASH client via unicast HTTP signaling.
