跟蹤小區(qū)Uu口信令發(fā)現(xiàn)，Activate PDP Context Reject主要原因均為：protocol configuration options，而對應Rab Assignment Response-Failure原因為：TimeOut。經查, protocol configuration options對應解釋為：

The PDP primary context activation failed, the PDP context is not activated. One reason for failure is that the network rejected the activation attempt, which means the ACTIVATE PDP CONTEXT REJECT message was received. Another reason is e.g. that it was not possible to establish the needed LLC link in the GSM case.

從協(xié)議可以發(fā)現(xiàn)，原因有兩個方面，一個是網(wǎng)絡拒絕，另一個是無法建立LLC鏈路。

問題來了，有多少人遇見過此類問題，最終解決方案是核心網(wǎng)側還是RNC側，是通過什么手段解決的？
