Problems solved by technology

[0009] Neither the UE nor the MME will transmit the IMSI and IMEI information through the eNodeB network element. As long as the UE detects that there is a legal S-TMSI (S-Temporary Mobile Subscriber Identity, Temporary Mobile Subscriber Identity) stored locally, it will not report the IMSI and IMEI. Therefore, eNodeB cannot filter and report signaling to EMS according to IMSI and IMEI
[0010] The inventor found that the implementation in the prior art has the following problems: the MME or other core network equipment cannot provide the eNodeB or the EMS that manages the eNodeB with the IMSI or the S-TMSI corresponding to the IMEI, so that the eNodeB cannot perform S-TMSI based on the IMSI or IMEI. TMSI Single User Tracking

Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The unique identifier of UE in the LTE network is S-TMSI, and the allocation method of S-TMSI is as follows:

[0034] When the UE attaches to the MME, the MME will assign a GUTI (Globally Unique Temporary Identity) to the UE, such as figure 1 As shown, GUTI is composed of GUMMEI (Globally Unique MME Identifier, MME global unique identifier) ​​and M-TMSI (-Temporary Mobile Subscriber Identity, temporary identification of mobile users in MME); GUMMEI is composed of MCC (Mobile Country Code, country code of mobile subscribers) ), MNC (Mobile Network code, mobile network number) and MMEI (MME Identifier, MME identification); MMEI is composed of MMEGI (MME Group ID, MME group ID) and MMEC (MME Code, MME code). And S-TMSI is com...

Abstract

The embodiment of the invention discloses a single user tracking method, system and equipment. The method includes: obtaining the air interface link corresponding to the temporary mobile subscriber identity S-TMSI of the user terminal UE, the identifier of the dedicated S1 link corresponding to the S-TMSI of the UE, and the identifier of the dedicated S1 link of the UE. The corresponding International Mobile Subscriber Identity IMSI or International Mobile Station Equipment Identity IMEI; according to the obtained content, obtain the mapping relationship between the UE's IMSI or IMEI and the UE's S-TMSI; according to the UE's IMSI or IMEI into the tracking task list Query whether the UE is a UE to be tracked, and if so, report the signaling on the air interface link and dedicated S1 link corresponding to the S-TMSI of the UE. In the embodiment of the present invention, by obtaining the mapping relationship between the S-TMSI of the UE and the IMSI or IMEI, and then obtaining the IMSI or IMEI of the UE, the single user tracking function based on the IMSI or IMEI is realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a single user tracking method, system and equipment. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is an evolution technology of 3G, which has the characteristics of scalable bandwidth, low latency, high speed, support for interoperability with existing networks, high coverage, support for high-speed mobile, and reduced network construction costs. . An eNodeB (evolved NodeB, evolved base station) in an LTE network includes functions of an RNC (Radio Network Controller, radio network controller) and a NodeB network element in a 3G network. [0003] eNodeB single user tracking means that EMS (Element Management System, network element management system) initiates a designated IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) or IMEI (International Mobile Station Equipment Identity, International ...
