摘　　要：阐述了一种基于附着流程中S1U接口TEID的用户标识关联回填方法,其中用户标识包括了IMSI、MSISDN和IMEI。其特征在于,通过SGW或eNodeB分配的S1U接口的TEID将S1-MME接口的信令和S11接口的信令关联起来。由于S11接口信令中携带IMSI、MSISIDN和IMEI等信息,因此可以回填到S1-MME接口的消息中,从而提高S1-MME接口消息的IMSI、MSISIDN和IMEI回填率,保证S1-MME接口TDR话单的完整性和准确性。A backfill user identity method of S1U interface based on TEID interface is described. The user identity includes IMSI,MSISDN and IMEI. Its characteristic lies in,using SGW or e Node B assigned S1U interface TEID to associate the signaling of the S1-MME interface with the S11 interface signaling. As the S11 interface signaling carrier information such as IMEI,MSISIDN,and IMSI,can be filled to the S1-MME interface message,thus improving the S1-MME interface message MSISIDN,IMSI and IMEI backfill rate,to ensure the integrity and accuracy of the S1-MME interface TDR.
