Abstract: Various aspects and embodiments may provide seamless and resource efficient roaming for group call services on broadcast/multicast networks. In particular, upon a user equipment (UE) roaming or detecting an imminent move from a current Public Land Mobile Network (PLMN) to a Visited PLMN (VPLMN), an application server in a Home PLMN associated with the UE may determine whether to establish a multicast bearer in the VPLMN if the UE has pre-registered for group call services in the VPLMN and provide the UE with information about bearers that will support the group call services in the VPLMN. For example, the multicast bearer may be established in the VPLMN if a number of users actively participating in the VPLMN exceeds a threshold, or the group call services may alternatively be supported over unicast service only if the number of actively participating users in the VPLMN is below the threshold.

Abstract: Methods, systems, and devices for wireless communication are described that provide for scheduling different types of traffic within a data flow, and providing a different coverage enhancement (CE) levels for the different types of traffic. Lower priority traffic within the IP flow may be scheduled with a lower CE level and higher priority traffic within the data flow may be scheduled with a higher CE level. In some cases, the CE levels may be selected to allow for a delay budget that supports real-time communications, such as a voice over LTE (VoLTE) real-time voice communications for bandwidth limited devices or devices that are bandwidth unrestricted but having poor channel conditions.

Abstract: The disclosure is related to group communications over multicast services. A user equipment (UE) sends a registration request to a server, the registration request indicating communications group(s) in which the UE is interested, receives a message indicating a set of the communications groups that have been assigned pre-established multicast resources, receives call identifiers, the call identifiers mapped to group identifiers of each communications group in the set of the communications groups, stores a mapping of the call identifiers to the group identifiers, and maintains group call sessions for the set of the communications groups. The server receives the registration request, determines that the UE is provisioned for pre-established group calls, retrieves group identifiers for the communications groups, maps call identifiers to the group identifiers, notifies the UE of the set of the communications groups and the mapped call identifiers, and assigns multiple group calls onto pre-established multicast resources.

Abstract: In an embodiment, a communication device (e.g., a current floor arbitrator of the session, a proxy device, etc.) records a floor arbitration history that tracks one or more floor grants and one or more floor denials that occur while a first device is performing a floor arbitration function for the communication session with the communication group, and transmits some or all of the floor arbitration history to a second device during the communication session. The second device (e.g., a new floor arbitrator for the session, a late or re-joining participant to the communication session, etc.) participates in the communication session based at least in part upon the received floor arbitration history (e.g., by factoring the received floor arbitration history into future floor-related decisions, by selectively requesting particular missed portions of the communication session, etc.).

Abstract: In an embodiment, a P2P device discovers other P2P devices that belong to a P2P group. The P2P device calculates a reachability vector that indicates each discovered P2P device within a threshold number of P2P hops. The P2P device receives reachability vector(s) for each proximate P2P device in a set of proximate P2P devices discovered via the P2P discovery procedure. The P2P device ranks the P2P device and each proximate P2P device in the set of proximate P2P devices based on the calculated and received reachability vectors. The P2P device identifies a leader (e.g., the P2P device itself and/or one or more of the other P2P devices) that is responsible for performing a floor arbitration function for a P2P session from the ranked P2P devices based on the rankings, and participates in the P2P session by exchanging media in accordance with the floor arbitration function performed by the leader.
