Embodiment 1
[0085] This embodiment illustrates the specific implementation process that the source access network node sends the TRACE parameter to the target access network node by carrying the TRACE parameter in the Handover Request message.
[0086] like Figure 4 In the shown LTE handover process, the TRACE parameter is carried in the HandoverRequest message sent from the Source eNB to the Target eNB. These parameters include the reference identifier of the trace, which uniquely marks this trace session, and the system judges which trace this trace is based on this identifier; including parameters such as trace depth, which are used to describe the network node trace message Level of detail; such as: the interface type of the trace, the record identifier of the trace result of the trace command, the trace result will be put into the record body marked with the record identifier, and other information. After receiving the TRACE parameter, the Target eNB can track the user according to...
Embodiment 2
[0106] This embodiment illustrates that the source access network node uses the X2 message interface to add a new X2_Invoke_Trace message to transmit the TRACE parameter.
[0107] During the handover process, the Source eNB can send the X2_Invoke_Trace message to the Target eNB. In this embodiment, the message can be sent after the Source eNB receives the Handover Request acknowledge message from the Target NB in the LTE handover process. that is Figure 4 Implementation after step 406 in .
[0108] Table 12 is the X2_Invoke_Trace message sent by Source eNB to Target eNB: Direction; Source eNB→Target eNB

Embodiment 3
[0113] This embodiment illustrates the implementation of the CN node initiating a trace setting command to the target eNB after the handover is completed.
[0114] In implementation, it may not be necessary to forward the tracking control and configuration parameters from the source eNB to the target eNB during the handover request or handover process. Instead, it can be sent after the switch is complete, specifically at the Figure 4 Sent in step 411 in , and bring the trace reference to the CN node. Implementation can be done in Figure 4 The handover request (HO request) in step 404 brings the trace reference to the target eNB. In this way, after the CN node receives the HO complete message, it sends the trace control and configuration parameters to the target eNB according to the trace reference, and this process can also use the CN INVOKE TRACE message.
[0115] There is also a handover process in the LTE system, Figure 6 It is a schematic diagram of another switchin...
