A method includes identifying a first user device potentially associated with a biohazard and identifying a geographic area associated with the biohazard based on previous location information of the first user device. The method further includes identifying a another user device potentially associated with the biohazard based on the geographic area associated with the biohazard and previous location information of the other user device. The method further includes issuing a safety notification to the other user device, where the safety notification includes one or more of the geographic area associated with the biohazard, a safety status request, a safety status level of the first user device, a subset of the previous location information of the first user device, and a subset of the previous location information of the other user device.

A wireless local area network (WLAN) communication method and apparatus using multiple transmission speed partitioning and cooperative transmission are disclosed. The WLAN communication method includes transmitting, by access point to the nodes, transmission time slots, partitions and internal transmission priorities using transmission time slot information, partition information and internal transmission priority information, receiving uplink packet from one node, determining whether downlink data to be transmitted to the high speed or the low speed node is present, or not in the download queue, transmitting, if present, the downlink packet to the nodes, removing downlink data from the download queue for ACK, and transmitting, if not present, transmitting ACK to the nodes.

Systems, methods, and instrumentalities are disclosed for priority handling for ProSe Communications. A relay wireless transmit/receive unit (WTRU) may act as a relay between the network and the remote WTRU. The relay WTRU may receive a temporary mobile group identity (TMGI) request message from a remote WTRU. The TMGI request message may include a TMGI, a ProSe per packet priority level associated with the TMGI, etc. The relay WTRU may receive an evolved multimedia broadcast multicast service (eMBMS) data packet from a network. The eMBMS may be associated with the TMGI. The relay WTRU may apply the received ProSe per packet priority level associated with the TMGI to the received eMBMS data packet. The relay WTRU may relay the eMBMS data packet to the remote WTRU based on the ProSe per packet priority level. The relay WTRU may forward the eMBMS data packet to the remote WTRU via a PC5 interface.

A method, system and apparatus for group management for vehicle-to-anything (V2X) and Proximity Based Services (ProSe) groupcast. According to one aspect, a method in a wireless device (WD) includes discovering wireless devices (WDs) that are members of a group, and sending to the WDs that are members of the group a group discovery complete message. According to another aspect, a method in a WD includes listening for a group discovery signal indicating a group to which the WD belongs or seeks to join, and sending a group discovery response indicating that the WD seeks to join or remain in the indicated group.

An event subscription management method and an apparatus are provided. The method includes: receiving an indication message includes identification information of an event subscription, identification information of a user, and indication information, the identification information of the event subscription indicates a first event subscription of a user group to the user belongs, and the indication information indicates to cancel event detection of the user in the first event subscription; determining information about the first event subscription based on the indication message, where the information about the first event subscription includes group member information of the user group or information about a quantity of event reporting times of the user; and sending a delete message to a second network element, to indicate the second network element to delete the first event subscription.

An online signup method and an apparatus, the method including identifying, by a first core network element, that a terminal device needs to perform online signup, triggering, by the first core network element, online signup authentication of the terminal device, and sending, by the first core network element, in response to the online signup authentication of the terminal device succeeding, a first message to a second core network element, where the first message includes a first identifier of the terminal device, and requests that the second core network element generate or update a network subscription of the terminal device.

Disclosed is a method for a management of a subscriber identity module related data, the data at least defining a mode of the subscriber identity module, the method, performed by an apparatus, including: receiving data indicative of a behavior of a device; detecting a deviation in the behavior of the device provided with the subscriber identity module compared to the mode set for the subscriber identity module; generating, in response to the detection of the deviation, a control signal to reset the mode of the subscriber identity module to correspond to the behavior of the device. Also disclosed is an apparatus, to a communication system, and to a computer program.

Systems, methods, apparatuses, and computer program products for ad hoc group based services to support 5G system (5GS) scenarios such as, but not limited to, edge computing and time synchronization, are provided.

Techniques for notification handling based on identity and physical presence are described and may be implemented to determine whether to route a notification from a first device (e.g., a mobile device) to a second device (e.g., a display device) for output at the second device. Generally, the described implementations utilize sensor data captured at a physical location to detect and/or identify persons present at the physical location and to determine whether to route notifications between devices based on the detected persons/identities.

The present invention introduces a system, which comprises a telecommunication network structure, which can be called as an intelligent combination of Push-To-Talk (i.e. Direct Mode Operation, DMO) communication technique and cellular network application. The DMO can be set as a preferred choice if it is available. The subscriber devices retransmit (i.e. forward) the data message further until the message reaches the called subscriber terminal. The total cumulative hop between subscriber terminals may comprise both DMO-based hops and cellular connections. ID means are provided, and telemetric information can be sent from the terminals. The invention allows emergency information submissions from the terminals, and forced broadcast information from an administrator to the terminals as well. Dynamic Talk Groups (DTG) can be defined based on geographic locations on each registered user.
