[判断题]只有当一个PDP地址所对应的位于SGSN和GGSN中的PDP上下文都处于激活状态时,才可能对相应的PDP PDUs进行路由和转发。
The corresponding PDP PDUs can be routed and forwarded (under the PTP circumstance) only when the PDP contexts, both in GGSN and SGSN corresponding to a PDP address are activated.
A.正确
B.错误
[多选题]下面哪些情况,SGSN可以发起PDP上下文修改流程?()
Under the following situations, SGSN will initiate the PDP update flow: ( ).
A.RAB重建,发生QoS改变
During RAB recreation, the QoS changes.
B.PDP上下文处于激活状态下,SGSN之间的路由区更新
When the PDP context is in activated state, the routing area between SGSNs will be updated.
C.当HLR向SGSN插入用户数据且PDP上下文处于激活状态
When the PDP context is in activated state, the HLR inserts user data to the SGSN.
D.PDP上下文处于激活状态下,SGSN内的路由区更新
When the PDP context is in activated state, the routing area inside the SGSN is updated.

A.正确
B.错误
[多选题]SGSN对接GGSN,发送create pdp上下文,GGSN没响应可能的原因是()。
When the SGSN interconnects with the GGSN, after the SGSN sends a "create pdp context" message, if the GGSN does not make any response, what are the possible reasons? ( )
A.SGSN网管没设置GN vrfid,导致消息没发送出去
Gn vrfid is not configured on the SGSN OMM, so the message can not be sent out.
B.GN口路由不通,GGSN收不到消息
The route on the Gn interface fails, so the GGSN can not receive the message.
C.GGSN系统内部处理错误丢弃响应消息
The GGSN system discards the response message due to an internal processing error.
D.GGSN的GPTC地址被地址池引用
The GTPC address of the GGSN is used in the IP pool.
E.
F.1234
