Abstract: A user equipment transmits a request to configure a first network to transmit complementary content associated with multicast or broadcast content received at the user equipment from a second network. In some cases, the request is transmitted in response to the user equipment detecting that a quality of a signal received from the second network is below a threshold. In response to receiving the request, the first network is configured to transmit the complementary content. The complementary content is transmitted from the first network concurrently with transmitting the multicast or broadcast content from the second network. The user equipment combines the complementary content received from the first network with the multicast or broadcast content received from the second network.

Abstract: A network gateway provides first content in a first service flow associated with a user equipment. The network gateway also accesses a user context for the user equipment. The user context is generated based on user-specific information included in packets received from the user equipment. The network gateway transmits the second content to the user equipment in a second service flow via a transmission mode that is selected from one of a broadcast mode, a multicast mode, or unicast mode. The broadcast mode, multicast mode, or unicast mode is selected based on a user context for the user equipment. The user equipment receives the first content in the first service flow and the second content in the second service flow that is selectively broadcast, multicast, or unicast based on the user context. The user equipment combines the first content and the second content for display.

Abstract: A user equipment (UE) provides service continuity when the UE is about to move out of coverage of a Multimedia Broadcast Multicast Service (MBMS). The UE: receives MBMS data via an MBMS bearer; detects that the UE is suffering from a bad MBMS bearer condition; informs a server of the bad MBMS conditions to initiate switching to unicast; wherein, if there is downlink data to deliver during switching, the UE begins to receive the downlink data via unicast and to continues to receive downlink data via the MBMS bearer until the switching to the unicast bearer is complete. The UE is configured to determine a quality of the MBMS bearer relative to a threshold, which is dependent on service type, for indicating that the MBMS bearer quality is not acceptable. When the threshold is reached, the UE sends a message to the server.
