Embodiment Construction

[0021] figure 1 The system hardware consists of three parts: core network equipment EPC, small base station Femtocell and antenna. Among them, EPC is used for communication between Femtocell and the Internet; Femtocell is used for baseband and RF signal processing; antenna is used for directional aggregation of RF sending and receiving signals, which is convenient for the base station to accurately detect nearby mobile phone signals.

[0022] EPC includes MME, S-GW, S4-SGSN, HSS, P-GW, and PCRF. The main function of MME is to support NAS signaling and its security, management of TrackingArea list, P-GW and S-GW Selection, MME selection during cross-MME handover, SGSN selection during handover to 2G / 3G access system, user authentication, roaming control and bearer management, and communication between core network nodes of different 3GPP access networks Mobility management (terminated at S3 node), and UE reachability management in ECM-IDLE state (including control and executio...

Abstract

The mobile communication signal detection method based on micro-cell technology, the mobile communication signal detection process is to capture the IMSI number of the mobile phone: when the mobile phone initiates registration after reaching the reselection or handover condition, it will send two signalings to the target base station, of which One is Attach request, and the other is Tracking area update request. After receiving the above signaling, the base station stores it first, and then sends a signaling to the mobile terminal, which contains a message requesting IMSI. The mobile terminal receives the base station After the request signaling is sent out, a signaling with IMSI information will be sent back to the base station, and the base station will analyze the received signaling to obtain the device identification number in it, so as to achieve the detection signal.

Description

technical field [0001] The invention relates to the fields of wireless communication and mobile payment, in particular to a method and system for detecting mobile communication signals. Background technique [0002] Most of the current short-distance wireless signal detection systems are based on contactless radio frequency identification (RFID) technology or NFC technology evolved from RFID, and technologies such as integrated dedicated SIM cards to detect wireless signals, requiring the terminal under test to support The corresponding function or the replacement of the existing SIM card has certain limitations. [0003] Femtocell base station (Femtocell) uses the IP protocol, and is connected through the user's existing ADSL, LAN and other broadband circuits, and the remote end is connected from the IP network to the mobile network by a dedicated gateway. Its size is similar to that of an ADSL modem, and it is easy to install , automatic configuration, automatic network p...
