Patent number: 12382294Abstract: Aspects relate to user equipment (UE) to user equipment (UE-to-UE) relaying in a communication system. At least two remote UEs and a UE-to-UE relay receive provisioned security information from the wireless communication network, where the security information includes discovery parameters and relay security information. The security information provisioned by the wireless communication network is used to establish a connection between the two UEs and the UE-to-UE relay device including discovery of the UE-to-UE relay by the remote UEs. Furthermore, the provisioned security information is used to establish a secure connection between the two remote UEs via the UE-to-UE relay device.Type: GrantFiled: September 30, 2021Date of Patent: August 5, 2025Assignee: QUALCOMM IncorporatedInventors: Soo Bum Lee, Adrian Edward Escott, Anand Palanigounder

Publication number: 20250047479Abstract: Disclosed are wireless communications systems and techniques. For example, a wireless communication device (e.g., a user equipment (UE)) compares a first key identifier (generated from a key stored in a first storage unit, such as a universal subscriber identity module) to a second key identifier (stored in a second storage unit, such as non-volatile memory) to identify a mismatch between the key identifiers. Based on the mismatch, the device replaces, in the second storage unit, the second key identifier. In some examples, the device verifies integrity of a message using the key, replaces the second key identifier with the first key identifier, and updates a counter based on the message. In a second illustrative example, the device replaces the key with a replacement key, replaces the second key identifier with the third key identifier based on the replacement key, and resets a counter.Type: ApplicationFiled: July 22, 2024Publication date: February 6, 2025Inventors: Anand PALANIGOUNDER, Adrian Edward ESCOTT

Patent number: 12108486Abstract: Aspects directed towards steering of roaming (SoR) are disclosed. In one example, a communication from a public land mobile network (PLMN) is received by a user equipment (UE) in which the communication indicates an acceptance of a UE registration with the PLMN. This example further includes performing a determination of whether an SoR indicator associated with a home PLMN (HPLMN) is embedded within the communication. The UE then manages PLMN selection according to the determination. In another example, a UE is configured to operate according to an SoR configuration in which the UE is configured to ascertain whether an SoR indicator is embedded within a communication from a PLMN. An SoR indicator associated with an HPLMN is then generated and subsequently transmitted from the HPLMN to the UE via the PLMN.Type: GrantFiled: January 28, 2022Date of Patent: October 1, 2024Assignee: QUALCOMM IncorporatedInventors: Anand Palanigounder, Adrian Edward Escott, Lenaig Genevieve Chaponniere
