Embodiment Construction

[0044] The core idea of ​​the present invention is that the CN actively participates in the signaling tracking process, so as to ensure that the RNC can also perform accurate IMSI-based signaling tracking on the UE when the corresponding relationship between the TMSI and the IMSI changes.

[0045] In order to make the present invention clearer, the signaling tracking process implemented by querying the TMSI is first introduced in detail.

[0046] see figure 1 , is a schematic diagram of realizing signaling tracking of the UE based on the IMSI by querying the TMSI mechanism. The process of signaling tracking includes:

[0047] 1) RNC creates a tracking task after receiving a tracking request from OMC to track an IMSI;

[0048] 2) The RNC searches for the IMSI in the UE in the connected state, and if it finds it, it immediately performs signaling tracking on the UE; if it does not find it, it executes the subsequent process;

[0049] 3) RNC sends a TMSI request message with I...

Abstract

The invention discloses a signaling track method, which comprises: monitoring a temporary mobile station identifier TMSI corresponding to an identifier IMSI of a tracked international mobile user, updating a corresponding relationship of the IMSI and TMSI; performing signaling-track on a user equipment UE by using the updated corresponding relationship of the IMSI and TMSI. The invention solves the problem that wrong corresponding relationship of the IMSI and TMSI is saved due to the changes of the IMSI, ensures that the recorded corresponding relationship of the IMSI and TMSI is updated timely, and ensures the accuracy and integrality of the signaling track on the UE based on the IMSI. With the method, the invention also provides a signaling track device and a signaling track system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication signaling tracking, in particular to an IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) signaling tracking method, device and system. Background technique [0002] Signaling tracking is an effective means for data recording and error checking in mobile communication systems. Due to the movement of the user equipment (User Equipment, UE), the location is not fixed, but no matter how it moves, its IMSI will not change. Therefore, when the radio network controller (Radio Network Controller, RNC) needs to track a certain UE or locate a certain When there is a problem with the UE, IMSI-based signaling tracking can be used. [0003] Currently, the implementation process based on IMSI signaling tracking includes the following steps: [0004] 1. After the RNC receives a tracking request from the Operation Maintenance Center (OMC) to track an...
