Non-access stratum congestion indication

Aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may receive a procedure rejection message for non-cellular access from a network at a non-access stratum (NAS) layer, and provide a first congestion indication for non-cellular access from the NAS layer to a lower layer based at least in part on receiving the procedure rejection message. The UE may refrain from initiating establishment of the signaling connection at the lower layer based at least in part on the first congestion indication. Numerous other aspects are provided. 本公开内容的各个方面通常涉及无线通信。在一些方面中，用户设备(UE)可以在非接入层(NAS)层处从网络接收针对非蜂窝接入的过程拒绝消息，以及至少部分地基于接收过程拒绝消息来从NAS层向较低层提供针对非蜂窝接入的第一拥塞指示。UE可以至少部分地基于第一拥塞指示来在较低层处避免发起对信令连接的建立。提供大量其它方面。
