RM500U-CN 如何建立 Ethernet PDU Session?

Zhiyong · 2023 年11 月 29 日 03:34

在测试能够成功建立IP Session的情况下, 我使用 AT+QICSGP = 1,4,“default”,"","",0. 将PDP Type改为了 Ethernet.
从5G核心网看, Ethernet PDU Session 已经成功建立. 但UE模组始终报错, 且没有将接口 ifconfig up起来.

以下是拨号log.

Hi @Zhiyong
请问如果用普通的IP Type，不用Ethernet模式拨号会报错吗？

Zhiyong · 2023 年12 月 13 日 17:03

感谢您的回复。请求IP Type, 一旦UE上报状态表明Session建立成功, 就不会继续拨号. 并随后up接口获取IP.

而在我提供的log中, [11-29_02:08:35:852] AT< +QNETDEVSTATUS: 1,1, “Ethernet”,0.这表明以太网会话已成功建立，但 Quectel-CM拨号程序没有识别到以太网Session成功建立了，会继续拨号。我使用的 Quectel-CM 版本是Quectel_QConnectManager_Linux_V1.6.4, 简单查看了部分源代码, 确实没有对Ethernet Type Session的处理的相关内容。我还没有找到能解决这个问题的更新的版本. 如果有的话这将对我帮助很大.

此外，我在测试过程中还遇到了另一个令人头疼的问题。当以太网会话断开，我试图重新建立会话时，会收到这样的状态报告：at+qnetdevstatus: 1,0, “ipv4”,3331. 其中IPV4理应是 Ethernet 才对, 只有多次断电重启模块才能解决问题。也就是说，一旦以太网会话断开，模块随后请求的类型就会错误地从我设定的 Ethernet 变成 IPV4。
