摘要：
新SGSN从自旧SGSN的管理区域移动到新SGSN的管理区域的终端（1）接收位置更新消息，接收到位置更新消息的新SGSN向旧SGSN发送用于交接应对GTPv2的通信路径信息的GTPv2信号。旧SGSN在接收GTPv2信号时，作为用于所述终端（1）的已确立的逻辑性的通信路径保持了GTPv1的通信路径信息的情况下，对新SGSN响应附加有设定了根据GTPv1的通信路径信息的追加参数（24）的GTPv2信号。
摘要（英）：

The present invention is designed such that a new SGSN receives a location update message from a terminal (1) having moved from the management area of an old SGSN to the management area of the new SGSN, and the new SGSN having received the location update message sends a GTPv2 signal for getting communication path information corresponding to GTPv2, to the old SGSN. The old SGSN, upon receiving the GTPv2 signal, if holding communication path information of GTPv1 as a logical communication path established for the terminal (1), sends, as a response, a GTPv2 signal in which the communication path information by GTPv1 is set in an additional parameter 24, to the new SGSN.
