## Abstract

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.

## Claims

### Claim 1

A user equipment (UE) comprising:
a multimedia broadcast and multicast service (MBMS) access client to:
receive a media presentation description (MPD) including information associated with a plurality of dynamic adaptive streaming over hypertext transfer protocol (DASH) media segments that are available for MBMS transmission; and
receive a first DASH media segment, of the plurality of DASH media segments, via a MBMS broadcast transmission from a broadcast multicast service center (BMSC) via user service discovery (USD) signaling;
a proxy terminal having an HTTP server circuitry to:
modify the MPD to include information associated with a subset or superset of the plurality of DASH media segments received via the MBMS broadcast transmission, wherein the subset or superset corresponds to DASH media segments that are available for hypertext transfer protocol (HTTP) transmission to a DASH client of the UE; and
provide the modified MPD to the DASH client; and
the DASH client to:
send a HTTP request to the HTTP server circuitry to request the first DASH media segment; and
receive, in response to the HTTP request, the first DASH media segment from the HTTP server circuitry via a unicast HTTP message, the first DASH media segment to be displayed by the UE.

### Claim 2 (depends on 1)

The UE of claim 1, further comprising:
a cache coupled to the MBMS access client to store the received first DASH media segment, wherein the DASH client is to receive the first DASH media segment via the cache.

### Claim 3 (depends on 1)

The apparatus of claim 7, further comprising means for caching the received first DASH media segment prior to sending the first DASH media segment to the DASH client.

### Claim 11

One or more non-transitory computer-readable media having instructions, stored thereon, that, when executed cause a user equipment (UE) to:
receive a media presentation description (MPD) including information associated with a plurality of dynamic adaptive streaming over hypertext transfer protocol (DASH) media segments that are available for multimedia broadcast and multicast service (MBMS) transmission;
receive a MBMS broadcast transmission including a first DASH media segment of the plurality of DASH media segments, wherein the MBMS broadcast transmission is received from a broadcast multicast service center (BMSC) via user service discovery (USD) signaling;

receive a HTTP request from the DASH client of the UE to request the first DASH media segment; and
send, in response to the HTTP request, the first DASH media segment to the DASH client via a unicast HTTP message.

### Claim 12 (depends on 11)
