Abstract: Computer implemented methods, systems, and computer program products include program code executing on a processor(s) that obtains location data from a client (an encrypted and a timestamp comprising). The processor(s) stores, in a graphing database, a vertex representing the user in a graph. The processor(s) determines, based on comparing the encrypted geohash and the timestamp of the vertex to values in one or more vertices in the graph, that at least one additional user intersected with the user in physical space proximate to a given time. The processor(s) generates or updates, between the vertex of the user and the at least one vertex representing the at least one additional user, an edge in the graph to represents a direct contact between. The processor(s) applies, to the graph, a breath first search algorithm to the graph to identify one or more indirect contacts between users.

The data in the file service is synchronized by the userspace process to the kernel module.

Abstract: Systems and methods for multicast data traffic service continuity under multicast-broadcast services (MBS) operation during a radio resource control (RRC) state or mode transition are described. In some embodiments, a user equipment (UE) receives, from a network, while in an RRC connected mode, an RRC release message comprising an RRC inactive mode point to multipoint (PTM) configuration that uses an MBS session to receive multicast data traffic while the UE is in an RRC inactive mode; enters the RRC inactive mode from the RRC connected mode in response to the RRC release message; and uses the RRC inactive mode PTM configuration to receive, from the network, the multicast data traffic of the MBS session while the UE is in the RRC inactive mode. Cases where a UE instead re-uses an RRC connected mode PTM configuration after transitioning to the RRC inactive mode are also described. Analogous network behaviors are described.
