The embodiment of the invention discloses and the recognition methods of a kind of pseudo-base station, device and terminal are provided, communication terminal can be realized Access Network is authenticated, that is to say the described communication terminal authentication to base station, be conducive to ensureing the safety of end message (such as userspersonal information, personal property information etc.).It is described in detail individually below.
In order to be best understood from the recognition methods of a kind of pseudo-base station, device and the terminal that the embodiment of the present invention provides, the network architecture first embodiment of the present invention being suitable for below is described.Refer to the structural representation that Fig. 1, Fig. 1 are a kind of network architectures that the embodiment of the present invention openly provides.As it is shown in figure 1, this network architecture schematic diagram can include network side, base station side and user side.Wherein, described network side represents Access Network/core net；Described base station side includes at least one base station, and the various communication terminals for user side provide wireless coverage, it is achieved the transmission of wireless signals between communication network and communication terminal, in general base station correspondence/be equivalent to a community；Described user side includes at least one communication terminal；For a communication terminal, the Serving cell that described communication terminal is currently connected to is referred to as persistent district, described communication terminal can also detect the signal of other Serving cells, other Serving cells described are referred to as candidate cell, if having between other Serving cells described (that is to say described candidate cell) and described persistent district common factor (coverage intersect, coverage is against tangent etc.) referred to as described in the neighbor cell of persistent district.Wherein, described communication terminal can include but not limited to the subscriber equipmenies such as mobile unit, mobile phone, removable computer, panel computer, personal digital assistant (PersonalDigitalAssistant, PDA), media player, intelligent television, intelligent watch, intelligent glasses, Intelligent bracelet.
Operation principle about pseudo-base station and feature are described below, refer to Fig. 2, be the structural representation of a kind of pseudo-base station work.As shown in Figure 2, this structural representation includes pseudo-base station system (Fakebasestationsystem) and communication terminal (Terminal), described pseudo-base station system includes base station unit and (that is to say base station, Basestationunit), analog core network entity function MSC (MobileSwitchingCenterfunctionalsimulator), operating platform (that is to say Artificial Control platform, Manipulationplatform).Wherein, described base station unit is equivalent to pseudo-base station transmission unit and controller, complies fully with network communication protocol (such as GSM) specification, provides to communication terminal and eats dishes without rice or wine to access；The function such as described analog core network entity function MSC realizes channel distribution, location updating, refuse messages issue, completes the acquisition of end message (such as userspersonal information), and whole operating process also complies with network communication protocol specification；Described operating platform is equivalent to the background control system of pseudo-base station, can complete power adjustment, cell parameter is revised, write note, false network address issues, it is lawless person's platform that communication terminal is launched a offensive, is generally made up of the notebook computer being mounted with control software design.Current pseudo-base station is generally and is made up of a set of RF transceiver, MSC circuit devcie, notebook computer etc., and volume is little, it is possible to is placed in luggage case or knapsack and is transported near user residence, it is achieved the attack to communication terminal.
Understandable, pseudo-base station system is generally operational in one GSM frequency of GSM900 frequency range (because multiple frequencies need to increase RF transceiver, increase cost and volume, weight etc.), the carrier frequency information of current goal origin base station can be scouted, the frequency of self is changed to existing network frequency, simultaneously the transmitting power of adjustable self.Communication terminal detects periphery neighboring area signal in an idle state always, when neighbor received signal intensity is more than current Serving cell with regard to gravity treatment to this adjacent area.During pseudo-base station work, by strengthening transmitting power, adjust and be conducive to the parameter toward adjacent area (pseudo-base station community) gravity treatment, can make rapidly the communication terminal gravity treatment of periphery idle condition in pseudo-base station community；Then pseudo-base station is set up with communication terminal to be connected and is carried out Signalling exchange, obtain the IMSI (InternationalMobileSubscriberIdentity of each terminal, international mobile subscriber identity), TMSI (TemporaryMobileSubscriberIdentity, Temporary Mobile Subscriber Identity) etc. information, carry out refuse messages, false network address issues, and gains the information such as user's account No. password by cheating；Last pseudo-base station release communication terminal, described communication terminal launch position updates and again resides in real network.
