MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202647125173 A) filed by Telefonaktiebolaget Lm Ericsson Publ on October 21, 2026, for Network Control Of User Equipment Security Key Updates For Mobility.
Inventors include Wager, Stefan; Orsino, Antonino; Norrman, Karl; Wallentin, Pontus; and Da Silva, Icaro Leonardo.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: Embodiments include methods for user equipment (UE) configured for mobility between cells of a radio access network (RAN). Such methods include receiving, from a first RAN node via a serving cell, a mobility configuration comprising candidate configuration(s) for respective mobility candidate cell(s). Each candidate configuration includes a security cell set identifier for the mobility candidate cell. Such methods include receiving from the first RAN node a mobility command for execution of a mobility procedure to one of the mobility candidate cells as a target cell. Such methods include, during execution of the mobility procedure according to the mobility command, selectively updating access stratum (AS) security keys based on security cell set identifiers for the target cell and for the serving cell. Such methods include transmitting, to a second RAN node, a message indicating that the mobility procedure is complete. The message is secured using the selectively updated AS security keys.
