Samsung patents 5G method for identifying senders in critical data groups
Samsung describes a way for 5G devices to send short data messages to groups while including a specific user ID in the message. This allows the receiving devices to decode the ID and know exactly which sender sent the data. The system combines 5G communication with Internet of Things technology to manage these critical data sessions.
In the filing’s own words
The disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -Generation (4G) system with a technology for Internet of Things (IoT). A method is provided. The method includes transmitting by at least one sender, respective MCData User Identifier (ID) to at least one receiver User Equipment (UE), receiving, by the at least one receiver UE, the MCData User ID of the at least one sender UE, and decoding, by the at least one receiver UE, the received sender MCData User ID to identify the at least one sender UE, wherein the sender MCData User ID is included in one of a signaling payload message content and a MCData notification message sent by the at least one sender UE to the at least one receiver UE.
What exactly they claim (claim 1)
1. A method performed by a sender User Equipment (UE) for managing a mission critical data (MCData) session, the method comprising: initiating a transmission of short data service (SDS) group data; generating an SDS signaling payload message including a sender MCData user identifier (ID) and an extended application ID; and transmitting, to at least one receiver UE, the SDS signaling payload message including the sender MCData user ID and the extended application ID.
