A network entity controls delivery of information to user devices over bearer paths including unicast channels and multicast channels. The network entity may interoperate in any of a number of network architectures, including 3GPP Internet Protocol Multimedia Subsystem (IMS) and 3GPP2 Multimedia Domain (MMD). The network entity may provide functionality of a modified 3GPP2 Broadcast and Multicast Service (BCMCS) controller component configured to enable BCMCS signaling protocol transactions to occur over 3GPP IMS interfaces and/or 3GPP2 MMD interfaces. A network entity configured to interoperate in a 3GPP IMS and/or 3GPP2 MMD network architecture may provide network-mobile multimedia services to user devices. Content associated with the multimedia services may be stored in storage devices in the network. A common interface through which a network operator defines service-specific parameters of a number of unicast and multicast multimedia services deployed in a distribution network may be provided.

Unicasting and multicasting multimedia services

In a radio access network, techniques for multicasting information from a radio network controller to radio nodes. The techniques further include broadcasting the information from the radio nodes to mobile access terminals. The information can include content to be delivered to the access terminals.

Broadcasting in wireless systems

In addition to other aspects disclosed, in response to an attempt by an access terminal in a sector of a wireless network to provide push-to-media content to another access terminal, the push-to-media session content is transmitted from the first access terminal over a multicast flow to the other access terminal.

Multicasting push-to-media content

In addition to other aspects disclosed, in response to being informed by a controller of a flow for transmission to at least one access terminal in a wireless network, a master base station router assigns the flow to one of a plurality of slave base station routers to process the flow for transmission to the access terminal.
