  • Group addressed frame wireless transmission for constrained multi-link operation
    Patent number: 12225519
    Abstract: Multi-link operations can provide higher network throughput and improved network flexibility compared to traditional techniques for wireless communication. Embodiments of the present invention provide a method of frame transmission that prevents constrained MLDs from transmitting and receiving frames on multiple links simultaneously using a novel and reliable group addressed frame transmission schedule for constrained MLDs. Group addressed frames are frames that are transmitted to several devices (e.g., broadcast) listening on a wireless link. It is important to carefully schedule group addressed frames for reception by MLDs to prevent IDC interference. According to some embodiments, group addressed frames are only transmitted when all MLDs listening on a wireless link are not transmitting data to prevent IDC interference.

  • Authentication reject handling for SNPN-enabled UE
    Patent number: 12225375
    Abstract: A method of handling authentication reject upon accessing an SNPN using credentials from a credential holder is proposed. A UE is configured with a “list of subscriber data”. The UE selects an SNPN using the configured list of subscriber data, e.g., based on the SNPN selection parameters contained in a selected entry of the list of subscriber data. Based on the selected entry, the UE selects an SNPN, and then tries to access the selected SNPN using credentials supplied by a subscribed SNPN. When UE receives an authentication reject message from the network, UE considers that the selected entry of the list of subscriber data is invalid. However, other entries related to the current selected SNPN are still valid. UE is still able to access the current selected SNPN, using credentials supplied in another entry of the list of subscriber data.

  • Method to avoid bad user experience by using rapid initial IMS registration
    Patent number: 12225423
    Abstract: A method of improving user experience for initial IP Multimedia Subsystem (IMS) registration is proposed. When a UE boots up or leaves flight mode, the processor of the UE determines a period Tn of time for IMS PDN initial setup on a single Access-Stratum Network, starting from sending IMS PDN setup request. Upon expiration of Tn, the UE aborts the IMS PDN set up request, and performs IMS PDN set up on another Access-Stratum Network. As a result, it allows the UE to rapidly use IMS service when boots up or leaves flight mode.
