  • Publication number: 20230276337
    Abstract: Systems and methods for providing dynamic network slicing resource reselection for wireless communication are described. User equipments (UEs) may determine that network slicing resources utilized with respect to one or more applications are to be changed in run time, such as for more efficient operation in light of a change in power mode, throughput mode, latency mode, etc. A message indicating a cause for reselection of a current packet data unit (PDU) session association with an application may be provided to a UE route selection policy (URSP) manager. The URSP manager may reevaluate a current PDU session association with the application to determine if it is a best match with the cause. If no, a switch to a new PDU session association with the application may be made. If yes, the current PDU session association with the application may be maintained Other aspects and features are also claimed and described.

  • Publication number: 20230224806
    Abstract: Techniques to recover from authentication failure are disclosed. During authentication of a user equipment (UE) with a public land mobile network (PLMN), the UE may receive an AUTHENTICATION REJECT with an extensible authentication protocol (EAP)-failure message. When this occurs, instead of invalidating the universal subscriber identity module (USIM) of the UE, the UE can search for other PLMNs that can potentially pass the authentication challenge. If one is found, the UE can register with the found PLMN.

  • Publication number: 20230180309
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that it is operating in a dual-subscription mode that includes a first subscription and a second subscription. In some cases, the UE may include an application that is requesting to establish a data connection in accordance with an access preference rule for the application. The UE may determine that the access preference rule lacks a match among policies of a first route selection policy associated with the first subscription (e.g., a default subscription). The UE may then evaluate a second route selection policy associated with the second subscription for a policy that matches the access preference rule based on determining the lack of the match among policies of the first route selection policy. The UE may establish the data connection after evaluating the second route selection policy for the matching policy.
