Abstract
Wireless communication methods, devices, and systems to reduce latency when network access (e.g., cellular network access) is barred are described. A method includes receiving, by a user equipment (UE) from an application, a request for at least one of establishment of a packet data unit (PDU) session or uplink (UL) data transfer via a previously established PDU session. The method additionally includes evaluating that access to a first network (e.g., a 3rd Generation Partnership Project (3GPP) network) is barred. The method also includes determining that the access barring time exceeds a threshold, and checking, in response to the determining, that configured policies permit the PDU session to be on a second network (e.g., a non-3GPP network). The method further includes transferring data of the PDU session in accordance with the configured policies. Other aspects and features are also claimed and described.
