现有技术中 ，移动台 (Mobile Station, MS)和 GPRS服务支持节点 (Serving GPRS Support Node, SGSN)都包含非确认信息 (Unconfirmed Information, UI)帧发 送状态变量 V(U) ,用于记录下一个待发送的 UI帧的序号， V(U)的范围为 0 ~ 511 ,每发送完一个 UI帧后， V(U)加 1。 每个 UI帧中携带帧序号 N(U) , N(U) 的值等于发送该 UI帧时 V(U)的值。
移动台和 SGSN还都包含 UI帧接收状态变量 V(UR)，用于表示下一个期望 收到的 UI帧中的 N(U) ， V(UR)的范围是 0 ~ 511 ,每接收一个 UI帧后， V(UR) 加 1。 移动台或者 SGSN在收到 UI帧时 ，判断 N(U)是否合法，如果接收方的 V(UR)与接收到的 UI帧的 N(U) 满足（ V(UR) - 32 ) < N(U) < V(UR)，则认为 N(U) 非法，丢弃该 UI帧。
然而，在 MOCN网络中 ， 当移动台向第一 SGSN发送的附着请求 (Attach Request)被拒绝后，基站控制器 (Base Station Controller, BSC)将移动台向第一 SGSN发送的附着请求转发到第二 SGSN。 在基站控制器转发移动台发送的附着 请求消息给第二 SGSN前，移动台已经和第一 SGSN有过信令交互，此时移动 台的 VOJR)已经不是初始值 Cb当第二 SGSN向移动台发送附着接受消息 (Attach Accept)时，消息中携带的 NOJ) 可能因为会在（ V(UR) - 32 ) < N(U) < V(UR:>范围 内而被移动台丢弃，使得移动台无法附着到第二 SGSN ,导致重路由的失败。
