LTE terminal control method based on signaling procedure

Abstract

The present invention discloses an LTE terminal control method based on a signaling procedure. The method comprises the steps of: analyzing a system message block (SIB) broadcasted by a current serving cell base station, analyzing downlink signal sending frequencies and cell reselection priority of the serving cell and adjacent cells; sending LTE induction signals on the frequency having the maximum cell reselection priority in the adjacent cells and the serving cell; inducting an FDD-LTE terminal to initiate a tracking area updating (TAU) signaling procedure, sending a TAU rejection signalingto a terminal, and allowing the LTE terminal to initiate an Attach flow; extracting an IMSI ((International Mobile Subscriber Identity) carried by an Attach Request, and establishing a control whitelist and a control black list; sending an Attach rejection signaling of the EMM (EPS Mobile Management)cause being 8' LTE and non LTE services not allowed' to target users of the IMSI in the black list; and sending an Attach rejection signaling of the EMM cause being 12' Tracking area not allowed' to non-target users of the IMSI in the white list. The method can achieve identity identification ofthe target users, can complete communication blocking of the target users and can communication support for the non-target users. The method cannot influence the normal communication of the base station, cannot influence other systems of mobile communication networks, and is low in cost of required devices and low in transmitting power.

Description

technical field [0001] The invention relates to an LTE terminal management and control method based on signaling flow. Background technique [0002] While mobile phones bring convenience to people's communications, the problems of stealing and leaking secrets around them are becoming more and more serious. Therefore, the national secrecy work department has issued a series of regulations to restrict the use of mobile phones in secret-related places. To make these provisions effective implementation, must be supplemented by certain technical protection measures. [0003] In this case, the management and control equipment for LTE mobile phones will come into play. Mobile phone management and control equipment is a third-party device that is not attached to users and operators, and can be used independently to effectively control mobile phone communications. This kind of control is mainly reflected in the interference to the communication of some mobile phone users, so that ...

Problems solved by technology

Its shortcomings are also very obvious. During the working process of the blocker, the interference signal must be continuously transmitted; for the LTE system, the bandwidth of the interference signal cannot be dynamically adjusted according to the system bandwidth set by the operator within the current working range, and only 20M bandwidth can be used. Construct an interference signal; due to the large bandwidth of the interference signal, the power of the actual transmitted interference signal is also extremely high, and the interference is also unscreened, and the communication of all users in the interference area will be blocked
