Embodiment Construction

[0044] The existing signaling tracking methods have the following problems:

[0045] The eNB cannot know the IMSI of the UE, so it can only identify the UE through the S-TMSI of the UE and then perform signaling tracking, and the S-TMSI of the UE will only be delivered to the eNB after the UE accesses the core network, so the UE completes The air interface signaling interaction before access, that is, the Initial UE Message and the previous air interface signaling cannot be tracked; and when the S1 connection is interrupted, the eNB stops tracking, resulting in subsequent connection re-establishment requests sent by the eNB to the UE and RRC (wireless Resource control protocol) signaling such as the connection release request message cannot be tracked, thus, the signaling tracking information obtained by tracking the UE signaling is incomplete.

[0046] In order to solve the above problems, an embodiment of the present invention provides a signaling tracking method. Using this...

Abstract

The present invention provides a method, a device and a system for signaling tracking which relates to the field of mobile communication and solves the problem that the signaling tracking information obtained by signaling tracking is not integrated. The method includes: the evolved Node B (eNB) receives the tracking task parameters transmitted by the integrated network management, the tracking task parameters include the corresponding relationship between International Mobile Subscriber Identity (IMSI) and the Serving Temporary Mobile Subscriber Identity (S-TMSI) of the specified User Equipment (UE) to be tracked; the eNB identifies the UE according to the corresponding relationship between IMSI and S-TMSI, and tracks the related signaling of the UE. The signaling includes air-interface signaling. The technical solutions provided by the present invention adapts to the Evolved Universal Mobile Telecommunications System(UMTS)Terrestrial Radio Access Network (eUTRAN) network.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a signaling tracking method, device and system for implementing IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) air interface signaling in eUTRAN (Evolved UTRAN). Background technique [0002] Signaling tracking refers to the tracking of the signaling generated by the interaction between the mobile phone and the network side (including base station and core network) control messages during the business process, which is an effective means for data recording and error checking in the mobile communication system. Due to the movement of UE (User Equipment), its location is not fixed, but no matter how it moves, its IMSI identity will not change. The LTE system adopts a single-layer structure composed of eNB (evolved base station). Compared with the traditional 3G access network, LTE reduces the number of RNC (Radio Network Contr...
