请教下各位，华为Mate20X 5G手机，总是不发起PDU session establishment request是什么原因。
PS：手机的APN跟核心网保持一致，数据开关已打开，网络模式设置成PS Only

请问下是什么原因导致手机不会发起PDU session建立请求？

23502协议上描述：
A PDU Session establishment may correspond to:
- a UE initiated PDU Session Establishment procedure.
- a UE initiated PDU Session handover between 3GPP and non-3GPP.
- a UE initiated PDU Session handover from EPS to 5GS.
- a Network triggered PDU Session Establishment procedure. In this case the network sends the device trigger message to application(s) on the UE side. The payload included in Device Trigger Request message contains information on which application on the UE side is expected to trigger the PDU Session establishment request. Based on that information, the application(s) on the UE side trigger the PDU Session Establishment procedure. For more detail refer to clause 4.13.2.

正常的随机接入和注册过程，应该是UE发起的，如果UE没有发起，是UE的行为？
