Method and apparatus for broadcasting/multicasting content from mobile user equipment over an MBMS network

摘要

A communication system is provided for implementing a wireless packet broadcast or multicast service. The system includes at least one Radio Access Network (RAN) for communicating with a first UE over a first wireless interface and a General Packet Radio Service (GPRS) Support Node (SGSN) for communicating with the RAN over a second wireless packet interface. A gateway GPRS support node (GGSN) is provided for communicating with the SGSN over a third wireless packet interface and for communicating with external packet-switched networks. A UE Broadcast/Multicast (UEBM) session manager is also provided, which is configured to provision a wireless packet broadcast or multicast service initiated by the first UE.

1. A communication system for implementing a wireless packet broadcast or multicast service, comprising:
at least one Radio Access Network (RAN) for communicating with a first UE over a first wireless interface; a UE Broadcast/Multicast (UEBM) session manager configured to provision a wireless packet broadcast or multicast service initiated by the first UE, to deliver content from the first UE to a list of recipient UEs, to query the recipient UEs as to whether they will be joining the wireless packet broadcast or multicast service initiated by the first UE, and to report to the first UE as to whether the recipient UEs will be joining the wireless packet broadcast or multicast service, wherein at least one of a start time of the wireless packet broadcast or multicast service and a list of recipient UE's is identified to the UEBM by the first UE, wherein the UEBM informs the first UE at the start time that transmission may begin, and wherein the content is received by the UEBM from the first UE after the start time and streamed to the list of recipient UE's by the UEBM over an MBMS bearer service plane after the start time; and a radio service support node for: communicating with the RAN over a second wireless packet interface; and a gateway support node for communicating with the radio service support node over a third wireless packet interface and for communicating with external packet-switched networks, and wherein the UEBM session manager is incorporated in the RAN, the radio service support node or the gateway support node.
