标题: PDN Connectivity Req with handover type [打印本页] 作者: wenliu 时间: 2013-3-21 16:05:24 标题: PDN Connectivity Req with handover type
今天查看现场的包，发现有个有趣的组合， PDN Connectivity Req 消息中request type =handover。奇怪了半天。因为同一个MME没看到有切换场景。
后来翻了24301 部分：
“The UE shall set the request type to "handover" when the connectivity to a PDN is established upon handover from a non-3GPP access network and the UE was connected to that PDN before the handover to the 3GPP access network.”
