  • Patent number: 9510160
    Abstract: A method between a controlling server and a participating server, a network, and a server include enhanced signaling via a Multicast-Broadcast Single Frequency Network (MBSFN) report allowing User Equipment (UE) to communicate MBSFN areas to a controlling server. Thus, the enhanced controlling server's Multimedia Broadcast Multicast Services (MBMS) decisions can count all visiting devices in addition to its own in its MBSFN areas. The method, network, and server include new signaling and additional info to provide a participating server with MBSFN areas that will have MBMS activated for a group session. This enhances the participating server's determination of which its visiting devices need unicast bearers. The participating server can add information related to the current MBSFN area of its UE to a message to the controlling server indicating joining the UE to a group.

  • Patent number: 9450991
    Abstract: A system and methods for increasing the granularity of privacy control in a group communication session are presented. A privacy rule is established for a participant in the session. The privacy rule specifies for different identity sharing triggers whether the participant identity is to be shared with other participants in the session. The privacy of the participant is able to be different dependent on the particular identity sharing trigger. The privacy rule is set by participant initiating the session, a separate server, or the participant. In the last case, the participant is able to specify privacy for a media or data stream when requesting the floor to transmit the stream. The identity of the participant is automatically modified dependent on session context information.

  • Patent number: 9392576
    Abstract: An infrastructure device in a 3GPP compliant system performs a method transporting a plurality of media streams over a shared MBMS bearer. The 3GPP compliant system includes a RAN partitioned into a plurality MBMS services areas, wherein each MBMS service area has at least one already existing shared MBMS bearers for transporting the media streams. The infrastructure device: receives a first request to transmit a first media stream to a first communication group; identifies a shared MBMS bearer in a first 3GPP MBMS service area that is already transporting a second media stream to a second communication group; and determines whether the shared MBMS bearer has sufficient capacity to transport both the first media stream and the second media stream simultaneously. When the shared MBMS bearer has sufficient capacity, the infrastructure device simultaneously sends both the first media stream and the second media stream on the shared MBMS bearer.
